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 injection 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 preure high preure 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 preure→high preure
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 preure 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
果是比较特殊的原料冷凝比较快的.则射口筒温度则不
3.中速段,在快速段结束后即转换成中速,中速的位
止比第二节法兰温度高10度.比如PPS.尼龙等.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
Nozzle temperature setting should low if product line.力则是20%-45%间.If resin material such as
In mid-speed section: Mold closing speed changes into
PPS, PA, cool very soon , Nozzle temperature should mid-speed after high-speed section finish.Mid-speed start higher more 10.C than the second cylinder temperature.position is where two plates meet(include three-plate mold and two-plate mold)Distance of mid-speed is up to
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-preure 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 preure 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-preure section: Mold closing sets low-preure 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
machine screen on this time.This point is the gage of the
Injection and plastic Technique parameter setting data.Data lower the point there is no high-preure.Data
higher the point there is high-preure easily.It set speed
一.注射 within 15-25% and preure within 1-2% depending on
type within 1-2% depending on type of injection molding
Injection machine.第四节常见塑料原料的有关温度值.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
原料 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
Resin名称 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.Name熔点℃
High-preure section: To normal injection molding
Melt’s成型温度℃machine, high-preure position had been set before they
were sent to customer.It can not be modified.For example
Molding Temperature(’c)分解温度℃ high-preure position of CHENHSONG machine is
50P.The speed of high-preure section is about 30-35%
Decomposing Temperature(‘C)模具温度℃ and higher than that of low-preure.The preure is up to mold, it can set within 55-85% For full-plate mold, it’s
Mold Temperature(‘c)干燥温度℃ eject air well, it can set preure 55%.If mold has a lot of slides and flash rate high in production, preure can set
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preure 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
preure 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 preure step: No matter what product there is
L: injection stroke Si: injection stroke a holding preure step.Any product can’t molding a same thickne.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 preure, The injection speed of holding preure step is slow but holding
Vi: injection volume of theoretical Ds: diameter of preure 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 preure.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 preure 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 preure is very the injection molding machine and mold structure important, Higher screw back preure ,higher quality of reasonable and eject air well, preure of this step should product screw back preure 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 preure too high.So all factors should be considered when using screw back preure.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 preure lower than that of
step2 To prevent flash speed and preure 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 preure 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.preure 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
Injection time consists holding preure time.Longer 把产品轻轻顶出一部分,然后是中压中速顶,中压中速一injection time, fuller product, we should consider 般指的是35%-55%,而低速则有可能低到5%,这需视产production quantity when we suit for quality.If injection 品不同而言,顶出行程设定是顶出长度稍比产品垂直深time too long, it may cause a series of defects suck as flash 度大1-2cm即可.strain.So all sorts of factors should be considered, injection time should be shout if quality suit for requirement.Knocking out includes two steps, Step1 section setting
mid-speed, knocks product out partly step2 section setting
2.熔胶时间的长短取决于熔胶速度设定的快慢,背压mid-preure and mid-speed.Depending on different 设定的大小,但有一点,熔胶时间控制的长短一定要比冷product, mid-preure and mid-speed sets within 35-55% 却时间短.but low-speed can set 5%.Distance of knocking out longer 1-2cm than the vertical thickne of product.Plastic time depends on plastic speed and screw back preure, but plastic time must shorter than cure time.二.退针
3.冷却时间:冷却时间的长短直接影响到成型的周期,Back
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
顶退包括两个过程与顶落的过程基本一致,顶退的会直接影响到变形等问题,设定的时间也是越短越好.终点应预留1-3cm的空间,以保护顶针油管不被顶坏.Cure time: Cure time affects molding cycle.Longer
The same as knocking out, ejector back includes 2
cure time, longer molding cycle, lower production quantity.steps.To protect the ejector oil jar, it should make a 1-3mm
So it sets cure time short on condition that product molding distance in the ending point of ejector back.succed and can’t deformation..三.顶针方式还包括一个多次顶,单次顶及顶针停留
4.在大量使用机械手的塑胶公司,我们的顶出时间一的选择,机械手取产品,脱模顺利的情况都采取多项,为了
般是与机械手配合为宜,全自动使用机械手时顶出停留顶针油缸 寿命的延长,多次顶就以不超过三次为宜,顶针
时间一般保持1.5-2秒,半自动生产,如因顶针退回会导致停留一般用在顶针带着产品退回有可能对增品产生损伤
产品掉落或卡紧,而取不下产品,停留时间则应保持5秒的模具,同时为配合机械手使用,有时也需要较短的顶针
左右.停留.In PCE company, for using manipulator in abundence ,The way of knocking out includes knocking out once, knocking out time suits manipulator, Knocking out delay Knocking out repeat and ejector delay.Take product by keeps 1.5-2 second when using manipulator full-manipulator or take product easy, it should select knocking manipulator, knocking out delay keeps about 5 second out once.To longer the work time of ejector oiljar, times of when using manipulator semi-manipulator and product will knocking out lower 3 times.Ejector delay used when fall or can’t be taken off if ejector back.product will be damaged if ejector back or suit manipulator.5.低压保护时间对保护我们人身安全,模具安全起很
成型时间的设定
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
Molding time setting
越小.Low-preure protect is very important for safety and protect mold, Mold protect time should adjust within 1-3 second suit low preure and position of mold protect, shorter protect time, make damaged.
