成型工艺参数的设定须根据产品的不同设置.Molding technique parameter setting differs depending on type of product 第二节成型条件设定

Section 2 Molding parameter Setting

按成型步骤:可分为开锁模,加热,射出,顶出四个过程.Molding steps: mold opening/closing, heating ※※※※ction and knocking out.开锁模条件:

Mold opening parameter:

快速段中速度

低压高压速度

High-speedmid-speed

Low pressure high pressure speed

锁模条件设定:

Mold closing parameter setting

1锁模一般分:快速→中速→低压→高压

Mold closing: high-speed →low-speed →low pressure→high pressure

2.快锁模一般按模具情况分,如果是平面二板模具,快速锁模段可用较快速度,甚至于用到特快,当用到一般快速时,速度设到55-75%,完全平面模可设定到80-90%,如果用到特快就只能设定在45-55%,压力则可设定于50-75%,位置段视产品的深浅(或长短)不同,一般是开模宽度的1/3.In high-speed section, Mold closing speed depends on type of mold.For two –plate mold it can set quick and even especially quick usually, it set speed within 55-75%.For full-plate mold it set speed within80-90% while using especially high speed it set speed within 45-55% and pressure within 50-75% position distance setting differs depending on the volume of product and usually it can be set 1/3 of mold opening position.3.中速段,在快速段结束后即转换成中速,中速的位置一般是到模板(包括三板模,二板模)合在一块为止,具体长度应视模板板间隔,速度一般设置在30%-50%间,压力则是20%-45%间.In mid-speed section: Mold closing speed changes into mid-speed after high-speed section finish.Mid-speed start position is where two plates meet(include three-plate mold and two-plate mold)Distance of mid-speed is up to distance of two plates plate it speed within 30-50% and pressure 20-45%.4.低压设定,低速设定一般是在模板接触的一瞬间,具体位置就设在机台显示屏显示的一瞬间的数字为准,这个数字一般是以这点为标准,即于此点则起不了高压,高于此点则大,轻易起高压.设定的速度一般是15%-25%,视乎不同机种而定,压力一般设定于1-2%,有些机则可设于5-15%,也是视乎不同机种不同.Low-pressure section: Mold closing sets low-pressure when plates meeting.This position is set to the data of machine screen on this time.This point is the gage of the data.Data lower the point there is no high-pressure.Data higher the point there is high-pressure easily.It set speed within 15-25% and pressure within 1-2% depending on type within 1-2% depending on type of ※※※※ction molding machine.5.高压设定,按一般机台而言,高压位置机台在出厂时都已作了设定,相对来讲,是不可以随便更改的,比如震雄机在50P.速度相对低压略高,大约在30-35%左右,而压力则视乎模具而定,可在55-85%中取,比如完全平面之新模,模具排气良好,甚至于设在55%即可,如果是滑块较多,原来生产时毛边也较多,甚至于可设在90%还略显不足.High-pressure section: To normal ※※※※ction molding machine, high-pressure position had been set before they were sent to customer.It can not be modified.For example high-pressure position of CHENHSONG machine is 50P.The speed of high-pressure section is about 30-35% and higher than that of low-pressure.The pressure is up to mold, it can set within 55-85% For full-plate mold, it’s eject air well, it can set pressure 55%.If mold has a lot of slides and flash rate high in production, pressure can set 90%.加热工艺条件设定

Heating technique parameter setting

1.加热段温度设定必须按照产品所使用的原料的不同而不同,但却必须遵循一个这样的规则,即由射口筒到进科段温度是逐步递减的.且递减温度是以10.度为单位.The proper temperature setting differs depending on type of resin material, but it must be abide by a rule that temperature setting should diminish in step 10.C from nozzle to feeding resin material position.2特殊情况下.如料头抽丝,则射口筒温度应降低,如果是比较特殊的原料冷凝比较快的.则射口筒温度则不止比第二节法兰温度高10度.比如PPS.尼龙等.Nozzle temperature setting should low if product line.If resin material such as

PPS, PA, cool very soon , Nozzle temperature should higher more 10.C than the second cylinder temperature.3.机台马达启动温度视乎机台不同而不同,一般出于对机台油路中的油封保护需要,油温最好能控制在40度-60度,以免油封长期高压而变化,缩短使用寿命,造成成型不稳定.Pump turning on temperature is different depending on type of ※※※※ction molding machine.To protect oil seal of machine it set oil temperature within 40.C-60.C, If oil seal work on condition that high pressure and damaged It’s work time will be shorter, it can cause molding stable.第三节注射及熔胶(加料)工艺条件设定

※※※※ction and plastic Technique parameter setting

一.注射

Resin dry temperature(‘c)

注射是把塑料原料经加热后射进模腔的过程,它一般可分为第一级,第二级,第三级,第四级及保压几段:

※※※※ction is a step which ※※※※ct melt resin material into mold.It consists of stepl,step2 ,step3,step4 and holding pressure step:

1.第一级注射一般是注射料头段.具注射量一般可根据料头的轻重来估计其行程,当然也可以依据公式来计算,如公式:

Step l ※※※※cts usually tunnel material, ※※※※ction Volume can be estimated according to the weight of course it can be calculated by formula:

L=Si=Vi/0.785Ds2

L:注射行程;Si:注射行程;

L: ※※※※ction stroke Si: ※※※※ction stroke

Vi:理论注射容积;Ds:螺杆直径;

Vi: ※※※※ction volume of theoretical Ds: diameter of screw

0.785:是Ω/4的值.0.785: value ofΩ/4.当然,如果我们在成型时每设定一个参数都要计算一次,要成型出一个产品就要几个小时才能完成了.But it cost a lot of time to produce one product if every time molding parameter is setting by calculation.2.第二级是注塑产品约2/3的阶段,当然,根据产品特殊需要,也允许成型不到2/3阶段,比如避免结合线问题,这一阶段的成型速度及压力一般是整个成型段的最大值段,如果排的产品与机台基本是相吻合的.模具结构合理,排气良好,这一段的压力一般也不会超过80%.速度侧视产品需变,可能大到95%也可,自然一般都是在55%-80%间.Step 2 ※※※※ct 2/3 of product.It can lower 2/3 of product according to requirement of product.For example to prevent weld line.Molding speed and pressure on this step is the maximum of whole molding section.If Mold suit the ※※※※ction molding machine and mold structure reasonable and eject air well, pressure of this step should lower 80%.Molding speed setting within 55-80% but it may setting 95% for especial product.3.第三段是注射余下的1/3段,其速度和压力根据产品的需要,一般是小于第二段,速度和压力存在于一个往下降的过程.主要是为了防止产品毛边的产生,但同时又必须把产品充填饱满.Step3 ※※※※ct remain 1/3 of product.According to product molding speed and pressure lower than that of step2 To prevent flash speed and pressure should decrease but it can’t shot short.4.第四段:一般有机台还有第五,第六段,这段的成型速度和压力相同前,都存在两段一个递减过程.其作用都是起到一个再次充满的作用.Step4 section: Some ※※※※ction machines have step5,step6 which are same as former molding speed and pressure this step should diminish and ※※※※ct once more.5.保压段:不论成型什么产品,都存在一个保压过程.任何产品都不同程度的存在一个厚薄不一的问题,正常情况下,较厚的部分都可能存在一个收缩凹陷的现象,为了解决这种现象,就应应用到保压,保压一般来讲都应用较慢的射速,而压力的设置则应看缩水的情况如何,小到25%,大到80%都有可能.Holding pressure step: No matter what product there is a holding pressure step.Any product can’t molding a same thickness.Usually the deeper section may sink mark.To prevent this defect it should set holding pressure, The ※※※※ction speed of holding pressure step is slow but holding pressure setting within 25-80% depending on sink mark.二.熔胶段工艺

Plastic Technique

1.再复杂的熔胶旋转过程最多不会超过三段,因为熔胶本身就是存在于把胶熔进料筒的过程,如果原料粘度大,熔胶压力则大,但速度则应取决于原料的分解温度,熔胶速度越快,原料中的剪切力则会越大,料管温度则越高,局部原料产生分解的可能性则会越大,故一般熔胶会采用中速为宜,如45%-75%,熔胶同时会碰到一个比较重要的环节,那就是背压的使用,产品精度要求越大,背压的使用则更大,背压可使原料分子间结构更紧密,成型出的产品则尺寸更稳定,外观越好.当然,背压太大,则会产生流涎,所以背压的使用又应考虙到其它原因.Plastic should lower 3 steps, because plastic is a step to add melt resin material to cyclinder , Higher stick of resin material ,higher screw back pressure.Screw speed differs depending on decomposing temperature of resin material ,Higher screw speed ,Higher trim force of resin, higher cyclinder temperature.Some resin material may decomposes so it set screw speed in mid-speed such as 45-75%, In plastic step setting screw back pressure is very important, Higher screw back pressure ,higher quality of product screw back pressure make resin structure order, Molding product is beautiful and volume stable.But ,it maybe flow if screw back pressure too high.So all factors should be considered when using screw back pressure.2.熔胶过程还有一个比较重要的环节,那就是松退,松退分前松退和后松退,其作用一般是为了防止流涎和抽丝,设定值速度和压力都在20%-50%间,设定的行程一般在2-5cm间,太长的行程可能会使料筒里面贮存空气,导致下一模出现不期望的气泡.In plastic step sucking back is very important too.Sucking back include front sucking back and back sucking back It setting sucking back to prevent flow and line.It sets sucking back speed and pressure within 20-50% and distance within 2-5cm.TOO long distance make cyclinder reserve air and cause bubble at next molding.顶出的工艺设定

knocking out technique setting

产品经冷却定型后则有一个开模的过程,开模基本上是合模的反过程.开模的未段则有一个慢速设置,开模完成后,产品必须顶出的过程.There is a mold opening step after product cooling taking shape.Mold opening is a reverse step of mold closing.The last step of mold opening speed set slow.Product should be knocked out after mold opened.一.顶前:

Knocking out

顶前最好分两个阶级,第一阶可分为中压慢速,即是把产品轻轻顶出一部分,然后是中压中速顶,中压中速一般指的是35%-55%,而低速则有可能低到5%,这需视产品不同而言,顶出行程设定是顶出长度稍比产品垂直深度大1-2cm即可.Knocking out includes two steps, Step1 section setting mid-speed, knocks product out partly step2 section setting mid-pressure and mid-speed.Depending on different product, mid-pressure and mid-speed sets within 35-55% but low-speed can set 5%.Distance of knocking out longer 1-2cm than the vertical thickness of product.第四节常见塑料原料的有关温度值.原料

第二篇:英语诗歌对比评析

Dingyu Wang(5***)Vy100 Professor Thorpe 11.22.2015

I Prefer Poets: Poets Can Do More than Barking In November 2011, Notch officially completed work on Minecraft 1.0, “an open world game that has no specific goals for the player to accomplish”(Gallegos), which turned out to be a huge success(McCarthy).McCarthy first regards its success as a mystery since it’s only an indie game without any advertising but he finally points out that the success is just because players“have free rein to build, build, build”(par.18).People do enjoythe freedom to think and create.In effect, the situation is analogical when people encounter poems.“Who Is a Poet” and “Another Reason I Don’t Keep a Gun in the House” are two poems that both take advantages of audience’s imagination in order to convey its message.However, “Who Is a Poet” provides more freedom for audience to understand and to imagine, thus giving a more effective argument, while “Another Reason I Don’t Keep a Gun in the House” restricts audience’s imagination in the author’s world by giving a detailed imaginary scene.The detailed reasons why “Who Is a Poet” is better than “Another Reason I Don’t Keep a Gun in the House” will be gradually revealed by analyzing the logos, ethos, and pathos in those poems.Billy Collinswrites “Another Reason I Don’t Keep a Gun in the House” in an imaginarily narrative way, encouraging people to seek joy amidst sorrow.In the poem, the neighbors’ dog keeps barking which almost drives the speaker craze.Then he falls into his imaginary world where the annoying dog becomes a soloist.The story that the speaker uses imagination to make an irritating dog so funny tells people not to be stuck by little annoyance and try to make life happier.Wang2

Alternatively, Tadeusz Różewicz writes “Who Is a Poet” to answer the question who is a poet.His argument is that poets are hard to define-anyone can be a poet under certain circumstances.Therefore, he actually gives a “vacant” definition of poets, and leaves the work to the audience who are guided to define their own poets.This kind of argument seems ridiculous but actually is a more effective way to argue such ill-defined items-it has no complete argument in the poem itself, but it has a unique argument once a reader start to read it.It’s the reader who completes the other half of the argument.Although the story in “Another Reason I Don’t Keep a Gun in the House” is quite interesting, it can only offer a very limited extent.“Who Is a Poet” does a much better job in offering chances for audience to think deeply.As a result, the latter one is superior to the former one in the interaction between poets and audience, which makes it a better argument.The logos,or the width of a poem’s context may wellconstrain the width of audience’s thoughts, thus playing an important role in an argument.The objects are very limited in “Another Reason I Don’t Keep a Gun in the House”-just the neighbors’ barking dog and the fictional dog soloist.Although that“dog” is likely to be a represent of all the annoyance, which provides a little more extent, the poem is far more restricted in comparison with “Who Is a Poet”.In “Who Is a Poet”,Różewicz covers both abstract and figurative parts about poets.Thanks to its complex context, readers are able to think over it in severallevels, thus obtaining profound understanding that comes from thinking deeply.Generally, the width of poems’ contexts provides objective condition for readers to think freely.The ethos,or the reading process of a poem, does matter a lot with respect to the effect of the argument.Collins’s story starts from a narrative of the actual barking dog and then turns into a narrative of a fictional dog soloist using a transitional sentence “and now I can see him sitting

Wang3

in the orchestra”(Collins).The transitional sentence is a signal and it’s so clear and obvious that people jump into that particular scene without any other thoughts.However, the literal meaning of “Who Is a Poet” is somehow contradictory-Różewicz states a poet can be both one who writes verses and one who doesn’t write verse(Różewicz).The literal contradiction can lead audience into deeper thoughts, thus being capable of sending more messages which are not on the surface of the poem.This kind of sentence-pairs also appears in the beginning of the novel Tale of Two Cities-“It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness …”(Dickens 8), which are a recognized extraordinary opening that constructs a solemn atmosphere.Such atmosphere helps people think deeply.The pathos isthe choice ofperson in poems.“Another Reason I Don’t Keep a Gun in the House” uses the first person which constrains the thoughts of readers, while “Who Is a Poet” is in the third person so that it can free the readers’ thoughts.Using the first person is known to be a good method to tell stories, though;it’s not a good idea to apply the first person in an argument.The use of “I” will absorb readers into the story and trap them within the story.Notice that although poems using the first person can take advantages of audience’s imagination,this kind of imagination is limitedwithin the author’s imagination.That is to say, the audience could at most imagine in the way the author imagines, being not able to go out of the author’s imagination.“Another Reason I Don’t Keep a Gun in the House” is actually an interesting poem with wild imagination, but after reading it, people only get the interesting idea of the barking dog and then little thing else.Alternatively, “Who Is a Poet” keeps in the third person and provides an insight of poets by offering a distance between readers and the characters in the poem.As a result, “Who Is a Poet” is also superior to “Another Reason I Don’t Keep a Gun in the House” according to the pathos.Wang4

“The message of the poem was defined as the interpretation of the poem, often linked to theme but encompassing more than that.It involves analyzing of unfolding what that would mean to the reader”(Patel).That’s true.Therefore, in order to “have something to be unfolded”, poems need some extra space that is left to readers, as opposed to proses, which are designed to instill the text into readers’ brain thus providing no extra space for readers.People prefer play games rather than watch television, for the former activity provides the freedom to think and create and Minecraft made a huge impact just by providing freedom for players.Not surprised, the poem “Who Is a Poet” which possessesan expansive width, a guidance of in-depth reading process, and the solemn use of the third person is superior to “Another Reason I Don’t Keep a Gun in the House”, for the former one has a higher degree of freedom provided for audience.According to the history of human beings’ exploration, in which humanbeings try again and again to free themselves from the limit of nature, human beings do pursue freedom, and do enjoy freedom, even when they are reading a poem.Wang5

2.快锁模一般按模具情况分,如果是平面二板模具,快速锁模段可用较快速度,甚至于用到特快,当用到一般快速时,速度设到55-75%,完全平面模可设定到80-90%,如果用到特快就只能设定在45-55%,压力则可设定于50-75%,位置段视产品的深浅(或长短)不同,一般是开模宽度的1/3.In high-speed section, Mold closing speed depends on type of mold.For two –plate mold it can set quick and even especially quick usually, it set speed within 55-75%.For full-plate mold it set speed within80-90% while using especially high speed it set speed within 45-55% and pressure within 50-75% position distance setting differs depending on the volume of product and usually it can be set 1/3 of mold opening position.3.中速段,在快速段结束后即转换成中速,中速的位置一般是到模板(包括三板模,二板模)合在一块为止,具体长度应视模板板间隔,速度一般设置在30%-50%间,压力则是20%-45%间.In mid-speed section: Mold closing speed changes into mid-speed after high-speed section finish.Mid-speed start position is where two plates meet(include three-plate mold and two-plate mold)Distance of mid-speed is up to distance of two plates plate it speed within 30-50% and pressure 20-45%.4.低压设定,低速设定一般是在模板接触的一瞬间,具体位置就设在机台显示屏显示的一瞬间的数字为准,这个数字一般是以这点为标准,即于此点则起不了高压,高于此点则大,轻易起高压.设定 的速度一般是15%-25%,视乎不同机种而定,压力一般设定于1-2%,有些机则可设于5-15%,也是视乎不同机种不同.Low-pressure section: Mold closing sets low-pressure when plates meeting.This position is set to the data of machine screen on this time.This point is the gage of the data.Data lower the point there is no high-pressure.Data higher the point there is high-pressure easily.It set speed within 15-25% and pressure within 1-2% depending on type within 1-2% depending on type of injection molding machine.5.高压设定,按一般机台而言,高压位置机台在出厂时都已作了设定,相对来讲,是不可以随便更改的,比如震雄机在50P.速度相对低压略高,大约在30-35%左右,而压力则视乎模具而定,可在55-85%中取,比如完全平面之新模,模具排气良好,甚至于设在55%即可,如果是滑块较多,原来生产时毛边也较多,甚至于可设在90%还略显不足.High-pressure section: To normal injection molding machine, high-pressure position had been set before they were sent to customer.It can not be modified.For example high-pressure position of CHENHSONG machine is 50P.The speed of high-pressure section is about 30-35% and higher than that of low-pressure.The pressure is up to mold, it can set within 55-85% For full-plate mold, it’s eject air well, it can set pressure 55%.If mold has a lot of slides and flash rate high in production, pressure can set 90%.加热工艺条件设定

Heating technique parameter setting 1.加热段温度设定必须按照产品所使用的原料的不同而不同,但却必须遵循一个这样的规则,即由射口筒到进科段温度是逐步递减的.且递减温度是以10.度为单位.The proper temperature setting differs depending on type of resin material, but it must be abide by a rule that temperature setting should diminish in step 10.C from nozzle to feeding resin material position.2特殊情况下.如料头抽丝,则射口筒温度应降低,如果是比较特殊的原料冷凝比较快的.则射口筒温度则不止比第二节法兰温度高10度.比如PPS.尼龙等.Nozzle temperature setting should low if product line.If resin material such as PS, PA, cool very soon , Nozzle temperature should higher more 10.C than the second cylinder temperature.3.机台马达启动温度视乎机台不同而不同,一般出于对机台油路中的油封保护需要,油温最好能控制在40度-60度,以免油封长期高压而变化,缩短使用寿命,造成成型不稳定.ump turning on temperature is different depending on type of injection molding machine.To protect oil seal of machine it set oil temperature within 40.C-60.C, If oil seal work on condition that high pressure and damaged It’s work time will be shorter, it

can cause molding stable.第三节注射及熔胶(加料)工艺条件设定

Injection and plastic Technique parameter setting 一.注射 Injection 第四节常见塑料原料的有关温度值.原料 Resin名称 Name熔点℃

Melt’s成型温度℃

Molding Temperature(’c)分解温度℃

Decomposing Temperature(‘C)模具温度℃

Mold Temperature(‘c)干燥温度℃

Resin dry temperature(‘c)

注射是把塑料原料经加热后射进模腔的过程,它一般可分为第一级,第二级,第三级,第四级及保压几段: Injection is a step which inject melt resin material into mold.It consists of stepl,step2 ,step3,step4 and holding pressure step: 1.第一级注射一般是注射料头段.具注射量一般可根据料头的轻重来估计其行程,当然也可以依据公式来计算,如公式: Step l injects usually tunnel material, Injection Volume can be estimated according to the weight of course it can be calculated by formula: L=Si=Vi/0.785Ds2 L:注射行程;Si:注射行程;L: injection stroke Si: injection stroke Vi:理论注射容积;Ds:螺杆直径;Vi: injection volume of theoretical Ds: diameter of screw 0.785:是Ω/4的值.0.785: value ofΩ/4.当然,如果我们在成型时每设定一个参数都要计算一次,要成型出一个产品就要几个小时才能完成了.But it cost a lot of time to produce one product if every time molding parameter is setting by calculation.2.第二级是注塑产品约2/3的阶段,当然,根据产品特殊需要,也允许成型不到2/3阶段,比如避免结合线问题,这一阶段的成型速度及压力一般是整个成型段的最大值段,如果排的产品与机台基本

是相吻合的.模具结构合理,排气良好,这一段的压力一般也不会超过80%.速度侧视产品需变,可能大到95%也可,自然一般都是在55%-80%间.Step 2 inject 2/3 of product.It can lower 2/3 of product according to requirement of product.For example to prevent weld line.Molding speed and pressure on this step is the maximum of whole molding section.If Mold suit the injection molding machine and mold structure reasonable and eject air well, pressure of this step should lower 80%.Molding speed setting within 55-80% but it may setting 95% for especial product.3.第三段是注射余下的1/3段,其速度和压力根据产品的需要,一般是小于第二段,速度和压力存在于一个往下降的过程.主要是为了防止产品毛边的产生,但同时又必须把产品充填饱满.Step3 inject remain 1/3 of product.According to product molding speed and pressure lower than that of step2 To prevent flash speed and pressure should decrease but it can’t shot short.4.第四段:一般有机台还有第五,第六段,这段的成型速度和压力相同前,都存在两段一个递减过程.其作用都是起到一个再次充满的作用.Step4 section: Some injection machines have step5,step6 which are same as former molding speed and pressure this step should diminish and inject once more.5.保压段:不论成型什么产品,都存在一个保压过程.任何产品都不同程度的存在一个厚薄不一的问题,正常情况下,较厚的部分都可能存在一个收缩凹陷的现象,为了解决这种现象,就应应用到保压,保压一般来讲都应用较慢的射速,而压力的设置则应看缩水的情况如何,小到25%,大到80%都有可能.Holding pressure step: No matter what product there is a holding pressure step.Any product can’t molding a same thickness.Usually the deeper section may sink mark.To prevent this defect it should set holding pressure, The injection speed of holding pressure step is slow but holding pressure setting within 25-80% depending on sink mark.二.熔胶段工艺 lastic Technique 1.再复杂的熔胶旋转过程最多不会超过三段,因为熔胶本身就是存在于把胶熔进料筒的过程,如果原料粘度大,熔胶压力则大,但速度则应取决于原料的分解温度,熔胶速度越快,原料中的剪切力则会越大,料管温度则越高,局部原料产生分解的可能性则会越大,故一般熔胶会采用中速为宜,如45%-75%,熔胶同时会碰到一个比较重要的环节,那就是背压的使用,产品精度要求越大,背压的使用则更大,背压可使原料分子间结构更紧密,成型出的产品则尺寸更稳定,外观越好.当然,背压太大,则会产生流涎,所以背压的使用又应考虙到其它原因.lastic should lower 3 steps, because plastic is a step to add melt resin material to cyclinder , Higher stick of resin material ,higher screw back pressure.Screw speed differs depending on decomposing temperature of resin material ,Higher screw speed ,Higher

trim force of resin, higher cyclinder temperature.Some resin material may decomposes so it set screw speed in mid-speed such as 45-75%, In plastic step setting screw back pressure is very important, Higher screw back pressure ,higher quality of product screw back pressure make resin structure order, Molding product is beautiful and volume stable.But ,it maybe flow if screw back pressure too high.So all factors should be considered when using screw back pressure.2.熔胶过程还有一个比较重要的环节,那就是松退,松退分前松退和后松退,其作用一般是为了防止流涎和抽丝,设定值速度和压力都在20%-50%间,设定的行程一般在2-5cm间,太长的行程可能会使料筒里面贮存空气,导致下一模出现不期望的气泡.In plastic step sucking back is very important too.Sucking back include front sucking back and back sucking back It setting sucking back to prevent flow and line.It sets sucking back speed and pressure within 20-50% and distance within 2-5cm.TOO long distance make cyclinder reserve air and cause bubble at next molding.顶出的工艺设定

knocking out technique setting 产品经冷却定型后则有一个开模的过程,开模基本上是合模的反过程.开模的未段则有一个慢速设置,开模完成后,产品必须顶出的过程.There is a mold opening step after product cooling taking shape.Mold opening is a reverse step of mold closing.The last step of mold opening speed set slow.Product should be knocked out after mold opened.一.顶前: Knocking out 顶前最好分两个阶级,第一阶可分为中压慢速,即是把产品轻轻顶出一部分,然后是中压中速顶,中压中速一般指的是35%-55%,而低速则有可能低到5%,这需视产品不同而言,顶出行程设定是顶出长度稍比产品垂直深度大1-2cm即可.Knocking out includes two steps, Step1 section setting mid-speed, knocks product out partly step2 section setting mid-pressure and mid-speed.Depending on different product, mid-pressure and mid-speed sets within 35-55% but low-speed can set 5%.Distance of knocking out longer 1-2cm than the vertical thickness of product.二.退针 Back 顶退包括两个过程与顶落的过程基本一致,顶退的终点应预留1-3cm的空间,以保护顶针油管不被顶坏.The same as knocking out, ejector back includes 2 steps.To protect the ejector oil jar, it should make a 1-3mm distance in the ending point of ejector back.三.顶针方式还包括一个多次顶,单次顶及顶针停留的选择,机械手取产品,脱模顺利的情况都采

取多项,为了顶针油缸 寿命的延长,多次顶就以不超过三次为宜,顶针停留一般用在顶针带着产品退回有可能对增品产生损伤的模具,同时为配合机械手使用,有时也需要较短的顶针停留.The way of knocking out includes knocking out once, Knocking out repeat and ejector delay.Take product by manipulator or take product easy, it should select knocking out once.To longer the work time of ejector oiljar, times of knocking out lower 3 times.Ejector delay used when product will be damaged if ejector back or suit manipulator.成型时间的设定 Molding time setting 在保证产品质量的前提下,周期时间是越短越好,周期时间又包括如下几项:射胶时间,保压时间,熔胶时间,冷却时间,顶出时间,锁模低压时间,甚至乎关系到时间因素的还有还开模与锁模,及顶出的快慢.Cycle time should shorter on condition that product quality well.Cycle time includes: injection time , holding pressure time, plastic time, cure time, knocking out time and mold protect time.Even mold opening closing sopeed and knocking out speed affect cycle.1.射胶时间包含保压时间,一般看起来,射胶时间越长,产品越饱和,但我们在讲求质量时,同时也须考虑产能,更何况,射胶时间过长,有可能会造成产品过于饱满而寻致粘模顶的变形呎寸偏大等一系列问题,故我们在设置射胶时间时应综合考虑,尽量在合乎质量要求时缩短射胶时间.Injection time consists holding pressure time.Longer injection time, fuller product, we should consider production quantity when we suit for quality.If injection time too long, it may cause a series of defects suck as flash strain.So all sorts of factors should be considered, injection time should be shout if quality suit for requirement.2.熔胶时间的长短取决于熔胶速度设定的快慢,背压设定的大小,但有一点,熔胶时间控制的长短一定要比冷却时间短.lastic time depends on plastic speed and screw back pressure, but plastic time must shorter than cure time.3.冷却时间:冷却时间的长短直接影响到成型的周期,冷却时间越长,成型时间就越长,造成产能就越低,故我们在设定高压冷却时间时,只要能保证到产品成型顺利,不会直接影响到变形等问题,设定的时间也是越短越好.Cure time: Cure time affects molding cycle.Longer cure time, longer molding cycle, lower production quantity.So it sets cure time short on condition that product molding succed and can’t deformation..4.在大量使用机械手的塑胶公司,我们的顶出时间一般是与机械手配合为宜,全自动使用机械手时顶出停留时间一般保持1.5-2秒,半自动生产,如因顶针退回会导致产品掉落或卡紧,而取不下产品,停留时间则应保持5秒左右.In PCE company, for using manipulator in abundence , knocking out time suits

manipulator, Knocking out delay keeps 1.5-2 second when using manipulator full-manipulator, knocking out delay keeps about 5 second when using manipulator semi-manipulator and product will fall or can’t be taken off if ejector back.5.低压保护时间对保护我们人身安全,模具安全起很大作用,配合好模具低压位置和低压压力的调整,低压保护的时间应取1-3秒,保护时间越短,可能造成的危害则越小.Low-pressure protect is very important for safety and protect mold, Mold protect time should adjust within 1-3 second suit low pressure and position of mold protect, shorter protect time, make damaged.Surface Appearance 外观 Glossiness/gloss finish 光洁度 Matt finish/matt surface 毛面

Mold closing: high-speed →low-speed →low pressure→high pressure

2.快锁模一般按模具情况分,如果是平面二板模具,快速锁模段可用较快速度,甚至于用到特快,当用到一般快速时,速度设到55-75%,完全平面模可设定到80-90%,如果用到特快就只能设定在45-55%,压力则可设定于50-75%,位置段视产品的深浅(或长短)不同,一般是开模宽度的1/3.同而不同,但却必须遵循一个这样的规则,即由射口筒到

In high-speed section, Mold closing speed depends on 进科段温度是逐步递减的.且递减温度是以10.度为单位.type of mold.For two –plate mold it can set quick and even

especially quick usually, it set speed within 55-75%.For

The proper temperature setting differs depending on full-plate mold it set speed within80-90% while using type of resin material, but it must be abide by a rule that especially high speed it set speed within 45-55% and temperature setting should diminish in step 10.C from pressure within 50-75% position distance setting differs nozzle to feeding resin material position.depending on the volume of product and usually it can be set 1/3 of mold opening position.2特殊情况下.如料头抽丝,则射口筒温度应降低,如

3.机台马达启动温度视乎机台不同而不同,一般出于distance of two plates plate it speed within 30-50% and 对机台油路中的油封保护需要,油温最好能控制在40度-pressure 20-45%.60度,以免油封长期高压而变化,缩短使用寿命,造成成型

不稳定.4.低压设定,低速设定一般是在模板接触的一瞬间,具体位置就设在机台显示屏显示的一瞬间的数字为准,Pump turning on temperature is different depending on 这个数字一般是以这点为标准,即于此点则起不了高压,type of injection molding machine.To protect oil seal of 高于此点则大,轻易起高压.设定的速度一般是15%-25%,machine it set oil temperature within 40.C-60.C, If oil seal 视乎不同机种而定,压力一般设定于1-2%,有些机则可设work on condition that high pressure and damaged It’s

work time will be shorter, it can cause molding stable.于5-15%,也是视乎不同机种不同.Low-pressure section: Mold closing sets low-pressure 第三节注射及熔胶(加料)工艺条件设定 when plates meeting.This position is set to the data of

Resin dry temperature(‘c)90%.注射是把塑料原料经加热后射进模腔的过程,它一

加热工艺条件设定

般可分为第一级,第二级,第三级,第四级及保压几段:

Heating technique parameter setting

Injection is a step which inject melt resin material into

mold.It consists of stepl,step2 ,step3,step4 and holding

1.加热段温度设定必须按照产品所使用的原料的不pressure step: 是起到一个再次充满的作用.1.第一级注射一般是注射料头段.具注射量一般可根

Step4 section: Some injection machines have 据料头的轻重来估计其行程,当然也可以依据公式来计step5,step6 which are same as former molding speed and

pressure this step should diminish and inject once more.算,如公式:

5.保压段:不论成型什么产品,都存在一个保压过程.Step l injects usually tunnel material, Injection Volume can be estimated according to the weight of course 任何产品都不同程度的存在一个厚薄不一的问题,正常it can be calculated by formula: 情况下,较厚的部分都可能存在一个收缩凹陷的现象,为 了解决这种现象,就应应用到保压,保压一般来讲都应用

L=Si=Vi/0.785Ds2 较慢的射速,而压力的设置则应看缩水的情况如何,小到

25%,大到80%都有可能.L:注射行程;Si:注射行程;

Holding pressure step: No matter what product there is

L: injection stroke Si: injection stroke a holding pressure step.Any product can’t molding a same thickness.Usually the deeper section may sink mark.To

Vi:理论注射容积;Ds:螺杆直径;prevent this defect it should set holding pressure, The injection speed of holding pressure step is slow but holding

Vi: injection volume of theoretical Ds: diameter of pressure setting within 25-80% depending on sink mark.screw

二.熔胶段工艺

0.785:是Ω/4的值.Plastic Technique

0.785: value ofΩ/4.1.再复杂的熔胶旋转过程最多不会超过三段,因为熔

当然,如果我们在成型时每设定一个参数都要计算胶本身就是存在于把胶熔进料筒的过程,如果原料粘度一次,要成型出一个产品就要几个小时才能完成了.大,熔胶压力则大,但速度则应取决于原料的分解温度,熔

胶速度越快,原料中的剪切力则会越大,料管温度则越高,But it cost a lot of time to produce one product if every

局部原料产生分解的可能性则会越大,故一般熔胶会采time molding parameter is setting by calculation.用中速为宜,如45%-75%,熔胶同时会碰到一个比较重要

2.第二级是注塑产品约2/3的阶段,当然,根据产品特的环节,那就是背压的使用,产品精度要求越大,背压的使殊需要,也允许成型不到2/3阶段,比如避免结合线问题,用则更大,背压可使原料分子间结构更紧密,成型出的产这一阶段的成型速度及压力一般是整个成型段的最大值品则尺寸更稳定,外观越好.当然,背压太大,则会产生流涎,段,如果排的产品与机台基本是相吻合的.模具结构合理,所以背压的使用又应考虙到其它原因.排气良好,这一段的压力一般也不会超过80%.速度侧视

Plastic should lower 3 steps, because plastic is a step 产品需变,可能大到95%也可,自然一般都是在55%-80%

to add melt resin material to cyclinder , Higher stick of 间.resin material ,higher screw back pressure.Screw speed differs depending on decomposing temperature of resin

Step 2 inject 2/3 of product.It can lower 2/3 of material ,Higher screw speed ,Higher trim force of resin, product according to requirement of product.For example higher cyclinder temperature.Some resin material may to prevent weld line.Molding speed and pressure on this decomposes so it set screw speed in mid-speed such as 45-step is the maximum of whole molding section.If Mold suit 75%, In plastic step setting screw back pressure is very the injection molding machine and mold structure important, Higher screw back pressure ,higher quality of reasonable and eject air well, pressure of this step should product screw back pressure make resin structure order, lower 80%.Molding speed setting within 55-80% but it Molding product is beautiful and volume stable.But ,it may setting 95% for especial product.maybe flow if screw back pressure too high.So all factors should be considered when using screw back pressure.3.第三段是注射余下的1/3段,其速度和压力根据产

品的需要,一般是小于第二段,速度和压力存在于一个往

2.熔胶过程还有一个比较重要的环节,那就是松退,下降的过程.主要是为了防止产品毛边的产生,但同时又松退分前松退和后松退,其作用一般是为了防止流涎和必须把产品充填饱满.抽丝,设定值速度和压力都在20%-50%间,设定的行程一 般在2-5cm间,太长的行程可能会使料筒里面贮存空气,Step3 inject remain 1/3 of product.According to

导致下一模出现不期望的气泡.product molding speed and pressure lower than that of

step2 To prevent flash speed and pressure should decrease

In plastic step sucking back is very important too.but it can’t shot short.Sucking back include front sucking back and back sucking

back It setting sucking back to prevent flow and line.It sets

4.第四段:一般有机台还有第五,第六段,这段的成型sucking back speed and pressure within 20-50% and 速度和压力相同前,都存在两段一个递减过程.其作用都distance within 2-5cm.TOO long distance make cyclinder reserve air and cause bubble at next molding.在保证产品质量的前提下,周期时间是越短越好,周顶出的工艺设定 期时间又包括如下几项:射胶时间,保压时间,熔胶时间,冷 却时间,顶出时间,锁模低压时间,甚至乎关系到时间因素

knocking out technique setting 的还有还开模与锁模,及顶出的快慢.产品经冷却定型后则有一个开模的过程,开模基本

Cycle time should shorter on condition that product 上是合模的反过程.开模的未段则有一个慢速设置,开模quality well.Cycle time includes: injection time , holding 完成后,产品必须顶出的过程.pressure time, plastic time, cure time, knocking out time and mold protect time.Even mold opening closing sopeed

There is a mold opening step after product cooling and knocking out speed affect cycle.taking shape.Mold opening is a reverse step of mold closing.The last step of mold opening speed set slow.1.射胶时间包含保压时间,一般看起来,射胶时间越Product should be knocked out after mold opened.长,产品越饱和,但我们在讲求质量时,同时也须考虑产能, 更何况,射胶时间过长,有可能会造成产品过于饱满而寻

一.顶前: 致粘模顶的变形呎寸偏大等一系列问题,故我们在设置

射胶时间时应综合考虑,尽量在合乎质量要求时缩短射

Knocking out

胶时间.顶前最好分两个阶级,第一阶可分为中压慢速,即是

第五篇:英语培训机构对比

英语培训机构特点整理

一、李阳疯狂英语——让三亿中国人讲一口流利的英语,让中国之声响彻全世界!李阳疯狂英语是在中国本土土生土长的实用高效的英语学习方法,在广大校园有很大的影响力。李阳文化教育发展有限公司由“疯狂英语”创始人李阳老师于一九九五年九月创建,是一家从事语言文化教育事业推广的企业;其前身是李阳•克立兹国际英语推广工作室。公司的中心品牌为“李阳疯狂英语”及“疯狂汉语”。李阳疯狂英语学校以一流的专业口语培训为龙头,在教学中坚持使用 “李阳疯狂英语快速突破法”和“李阳疯狂英语Emax 课文快速背诵法”为教学两大法宝,开设了三大类王牌课程,1.世界公认的一流的口语培训;

2.李阳疯狂英语Crazy Baby少儿英语专业培训;

3.李阳疯狂英语口语强化集训营。

在一个相对封闭的环境中, 要求学生在衣食住行的过程中只能使用英语,在短时间内形成英语思维习惯,适合学生参加。多以训练营、夏令营等短期全封闭培训为主,作为一种交新朋友、集体生活的体验对于学生来说,参加一次这样的英语培训也很不错。

总结:中国人喜欢的方法,注重口语的练习;已经做了20多年,说明其方法还是很有效果的,算是一大竞争对手。

美联的“体验式学习”具备以下一些特征:

Output: 在沙龙课,会话课上,以及美联创造的真实的语言使用环境中,学员要使用英文来完成各种真实的任务,比如采访新学员,获取外教信息等.是真正的task-based学习.语言变成了完成任务的工具,回归其社会属性。

个性化跟踪辅导: SA的跟踪辅导是美联英语最富特色和竞争力的教学服务内容和方式,充分体现了美联英语以学员为中心的核心理念。是指SA作为学习指导,对学员学习情况的跟踪及指导。SA从学员进校开始,就应该重点关注他们的学习方法,吸收的程度,及学习进度,督促和鼓励学员经常来校上机和上课, 帮助学员最大限度地利用教学资源,在学习期内成功完成学习。
