5、开锁模条件：Mold opening parameter:快速段中速度低压高压速度High-speedmid-speedLow pressure high pressure speed锁模条件设定：Mold closing parameter setting1锁模一般分:快速f中速f低压f高压Mold closing: high-speed -low-speed flow pressure-*high pressure2 .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

6、就只能设定在45-55%小力则可设定于50-75机位置 段视产品的深浅（或长短）不同，一般是开模宽度的1/3.speed depends on type and even especially full-plate mold it set speed it set speedIn high-speed section, Mold closing of mold. For two - plate mold it can set quick quick usually, it set speed within 55-75%. For speed within80-90% while using e

7、specially high 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%|,h,压力则是 20%-45%间.In mid-speed section: Mo

8、ld closing speed changes into midspeed 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

9、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5T5%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. Dat

10、a 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

11、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 ma

12、chine 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

13、set 90%.加热工艺条件设定Heating technique parameter setting1.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 nozzl

14、e 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笫二节法兰温度高10度.比如PPS. 尼龙等.Nozzle temperature setting should low if product line. If resin material such asPPS, PA, cool very soon , Nozzle temperature should higher more 10. C than the second cylinder temperature.3.

15、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 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 damag

16、ed 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 Temperaturec)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

17、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 1 injects usually tunnel material, Injection Volume can be estimate

18、d according to the weight of course it can be calculated by formula:L=Si=Vi/0. 785Ds2L:注射行程；Si:注射行程；L: injection stroke Si: injection strokeVi:理论注射容积；Ds:螺杆直径；Vi: injection volume of theoretical Ds: diameter of screw0.785:是 Q/4 的值.0. 785: value ofQ/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

19、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7/12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.

20、 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 shou

21、ld lower 80%. Molding speed setting within 55-80% but it may setting 95% for especial product.3 .笫三段是注射余下的1/3段,其速度和压力根据产品的需要,一般 是小于笫二段,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 preven

22、t 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

23、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 p

24、revent 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Plastic Technique1 .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

25、原料产生分解的可能性则会越大，故一般熔胶会采川中速为宜,如45375%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,背出太大,则会产生流涎,所以背压的使用乂应考虑到其它原因.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 pres

26、sure. 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

27、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

28、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%fR, 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

29、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 ope

30、ning 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,笫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l-2cm 即可.Knocking out includes two steps, Ste

31、pl section setting mid-speed, knocks product out partly step2 section setting midpressure 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 l-2cm than the vertical thickness of product.二退针Back顶退包括两个

32、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

33、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

34、 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,周期时间乂包括如 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 , hol

35、ding pressure time, plastic time, cure time, knocking out time and mold protecttime. 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欢!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 tim

36、e 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 q
