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 低压高压速度添加剂英文 High-speedmid-speed Low pressure high pressure speed 锁模条件设定: Mold closing parameter tting 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 ction, Mold closing speed depends on type of mold. For two –plate mold it can t quick and even especially quick usually, it t speed within 55-75%. For full-plate mold it t speed within80-90% while using especially
high speed it t speed within 45-55% and pressure within 50-75% position distance tting differs depending on the volume of product and usually it can be t 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%污染英文间. In mid-speed ction: Mold closing speed changes into mid-speed after high-speed ction 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 ction: Mold closing ts low-pressure when plates meeting. This position is t 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 t 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made in korea,比如完全平面之新模,模具排气良好,字母歌甚至于设在pointless55%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 ction: To normal injection molding machine, high-pressure position had been t before they were nt to customer. It can not be modified. For example high-pressure position of CHENHSONG machine is 50P.The speed of high-pressure ction is about 30-35% and higher than that of low-pressure. The pressure is up to mold, it can t within 55-85% For full-plate mold, it’s eject air well, it can t pressure 55% .If mold has a lot of slides and flash rate high in production, pressure can t 90%. 加热工艺条件设定 Heating technique parameter tting 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 tting differs depending on type of resin material, but it must be abide by a rule that temperature tting should diminish in step 10.C from nozzle to feeding resin ma
terial 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 tting should low if product line. If resin material such as PPS, PA, cool very soon , Nozzle temperature should higher more 10.C than the cond cylinder temperature. 3.出国出国留学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 al of machine it t oil temperature within 40.C-60.C, If oil al work on condition that high pressure and damaged It’s work time will be shorter, it can cau molding stable
