technique parameter setting differs depending on type of product 第二節(jié)成型條件設(shè)定Section 2 Molding parameter Setting 按成型步驟:可分為開(kāi)鎖模,加熱,射出, steps: mold opening/closing, heating injection and knocking : 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(zhǎng)短)不同,一般是開(kāi)模寬度的1/ highspeed section, Mold closing speed depends on type of 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 ,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(zhǎng)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% midspeed section: Mold closing speed changes into midspeed after highspeed section 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(tái)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, 的速度一般是15%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%, section: Mold closing sets lowpressure when plates position is set to the data of machine screen on this point is the gage of the lower the point there is no higher the point there is highpressure set speed within 1525% and pressure within 12% depending on type within 12% depending on type of injection molding ,按一般機(jī)臺(tái)而言,高壓位置機(jī)臺(tái)在出廠時(shí)都已作了設(shè)定,相對(duì)來(lái)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(lái)生產(chǎn)時(shí)毛邊也較多,甚至于可設(shè)在90% section: To normal injection molding machine, highpressure position had been set before they were sent to can not be example highpressure position of CHENHSONG machine is speed of highpressure section is about 3035% and higher than that of 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, 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 from nozzle to feeding resin material ,則射口筒溫度應(yīng)降低, temperature setting should low if product resin material such as PS, PA, cool very soon , Nozzle temperature should higher more than the second cylinder ,一般出于對(duì)機(jī)臺(tái)油路中的油封保護(hù)需要,油溫最好能控制在40度60度,以免油封長(zhǎng)期高壓而變化,縮短使用壽命, turning on temperature is different depending on type of injection molding protect oil seal of machine it set oil temperature within , If oil seal work on condition that high pressure and damaged It’s work time will be shorter, itcan cause

Temperature(‘c)干燥溫度℃Resin dry temperature(‘c)注射是把塑料原料經(jīng)加熱后射進(jìn)模腔的過(guò)程,它一般可分為第一級(jí),第二級(jí),第三級(jí),第四級(jí)及保壓幾段: Injection is a step which inject melt resin material into consists of stepl,step2 ,step3,step4 and holding pressure step: ,當(dāng)然也可以依據(jù)公式來(lái)計(jì)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/ L:注射行程。Si:注射行程。L: injection stroke Si: injection stroke Vi:理論注射容積。Ds:螺桿直徑。Vi: injection volume of theoretical Ds: diameter of screw :是Ω/: value ofΩ/,如果我們?cè)诔尚蜁r(shí)每設(shè)定一個(gè)參數(shù)都要計(jì)算一次, it cost a lot of time to produce one product if every time molding parameter is setting by ,當(dāng)然,根據(jù)產(chǎn)品特殊需要,也允許成型不到2/3階段,比如避免結(jié)合線問(wèn)題,這一階段的成型速度及壓力一般是整個(gè)成型段的最大值段,如果排的產(chǎn)品與機(jī)臺(tái)基本,排氣良好,這一段的壓力一般也不會(huì)超過(guò)80%.速度側(cè)視產(chǎn)品需變,可能大到95%也可,自然一般都是在55%80% 2 inject 2/3 of can lower 2/3 of product according to requirement of example to prevent weld speed and pressure on this step is the maximum of whole molding 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 5580% but it may setting 95% for especial ,其速度和壓力根據(jù)產(chǎn)品的需要,一般是小于第二段, inject remain 1/3 of to product molding speed and pressure lower than that of step2 To prevent flash speed and pressure should decrease but it can’t shot :一般有機(jī)臺(tái)還有第五,第六段,這段的成型速度和壓力相同前, section: Some injection machines have step5,step6 which are same as former molding speed and pressure this step should diminish and inject once :不論成型什么產(chǎn)品,正常情況下,較厚的部
