【正文】 。 開鎖模條件: Mold opening parameter: 快速段中速度 低壓高壓速度 Highspeedmidspeed Low pressure high pressure speed 鎖模條件設(shè)定: Mold closing parameter setting 1鎖模一般分:快速→中速→低壓→高壓 Mold closing: highspeed →lowspeed →low pressure→high pressure ,如果是平面二板模具,快速鎖模段可用較快速度,甚至于用到特快,當(dāng)用到一般快速時(shí),速度設(shè)到5575%,完全平面模可設(shè)定到8090%,如果用到特快就只能設(shè)定在4555%,壓力則可設(shè)定于5075%,位置段視產(chǎn)品的深淺(或長短)不同,一般是開模寬度的1/3. In highspeed 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 5575%. For fullplate mold it set speed within8090% while using especially high speed it set speed within 4555% and pressure within 5075% position distance setting differs depending on the volume of product and usually it can be set 1/3 of mold opening position. ,在快速段結(jié)束后即轉(zhuǎn)換成中速,中速的位置一般是到模板(包括三板模,二板模)合在一塊為止,具體長度應(yīng)視模板板間隔,速度一般設(shè)置在30%50%間,壓力則是20%45%間. In midspeed section: Mold closing speed changes into midspeed after highspeed section finish. Midspeed start position is where two plates meet (include threeplate mold and twoplate mold ) Distance of midspeed is up to distance of two plates plate it speed within 3050% and pressure 2045%. ,低速設(shè)定一般是在模板接觸的一瞬間,具體位置就設(shè)在機(jī)臺顯示屏顯示的一瞬間的數(shù)字為準(zhǔn),這個(gè)數(shù)字一般是以這點(diǎn)為標(biāo)準(zhǔn),即于此點(diǎn)則起不了高壓,高于此點(diǎn)則大,%25%,視乎不同機(jī)種而定,壓力一般設(shè)定于12%,有些機(jī)則可設(shè)于515%,也是視乎不同機(jī)種不同. Lowpressure section: Mold closing sets lowpressure 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 highpressure. Data higher the point there is highpressure easily. It set speed within 1525% and pressure within 12% depending on type within 12% depending on type of injection molding machine. ,按一般機(jī)臺而言,高壓位置機(jī)臺在出廠時(shí)都已作了設(shè)定,相對來講,是不可以隨便更改的,大約在3035%左右,而壓力則視乎模具而定,可在5585%中取,比如完全平面之新模,模具排氣良好,甚至于設(shè)在55%即可,如果是滑塊較多,原來生產(chǎn)時(shí)毛邊也較多,甚至于可設(shè)在90%還略顯不足. Highpressure section: To normal injection molding machine, highpressure position had been set before they were sent to customer. It can not be modified. For example highpressure position of CHENHSONG machine is speed of highpressure section is about 3035% and higher than that of lowpressure. The pressure is up to mold, it can set within 5585% For fullplate 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%. 加熱工藝條件設(shè)定 Heating technique parameter setting ,但卻必須遵循一個(gè)這樣的規(guī)則,. 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
