【正文】 plastic speed and screw back pressure, but plastic time must shorter than cure :冷卻時間的長短直接影響到成型的周期,Back冷卻時間越長,成型時間就越長,造成產能就越低,故我們在設定高壓冷卻時間時,只要能保證到產品成型順利,不頂退包括兩個過程與頂落的過程基本一致,頂退的會直接影響到變形等問題, time: Cure time affects molding The same as knocking out, ejector back includes 2cure time, longer molding cycle, lower production protect the ejector oil jar, it should make a 13mmSo it sets cure time short on condition that product molding distance in the ending point of ejector and can’t deformation..,單次頂及頂針停留,我們的頂出時間一的選擇,機械手取產品,脫模順利的情況都采取多項,為了般是與機械手配合為宜,全自動使用機械手時頂出停留頂針油缸 壽命的延長,多次頂就以不超過三次為宜,頂針,半自動生產,如因頂針退回會導致停留一般用在頂針帶著產品退回有可能對增品產生損傷產品掉落或卡緊,而取不下產品,停留時間則應保持5秒的模具,同時為配合機械手使用,有時也需要較短的頂針 PCE pany, 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 product by keeps second when using manipulator fullmanipulator or take product easy, it should select knocking manipulator, knocking out delay keeps about 5 second out longer the work time of ejector oiljar, times of when using manipulator semimanipulator and product will knocking out lower 3 delay used when fall or can’t be taken off if ejector will be damaged if ejector back or suit ,模具安全起很成型時間的設定大作用,配合好模具低壓位置和低壓壓力的調整,低壓保護的時間應取13秒,保護時間越短,可能造成的危害則Molding time setting protect is very important for safety and protect mold, Mold protect time should adjust within 13 second suit low pressure and position of mold protect, shorter protect time, make damaged.第三篇：注塑技術員考試文檔一位合格的注塑工作者應具備哪些專業(yè)知識？（7分）。第一篇：注塑技術員用英語全攻略注塑專業(yè)英語全攻略!成型工藝流程及條件介紹Molding technique procedure and parameter introduction 第一節(jié) 成型工藝Section 1 molding Sorts of molding

time lant timeKnocking out and delay time Mold protect time technique parameter setting differs depending on type of product 第二節(jié)成型條件設定Section 2 Molding parameter Setting 按成型步驟:可分為開鎖模,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,當用到一般快速時,速度設到5575%,完全平面?？稍O定到8090%,如果用到特快就只能設定在4555%,壓力則可設定于5075%,位置段視產品的深淺(或長短)不同,一般是開模寬度的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 ,在快速段結束后即轉換成中速,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,具體長度應視模板板間隔,速度一般設置在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%.,低速設定一般是在模板接觸的一瞬間,具體位置就設在機臺顯示屏顯示的一瞬間的數(shù)字為準,這個數(shù)字一般是以這點為標準，即于此點則起不了高壓,高于此點則大, 的速度一般是15%25%,視乎不同機種而定,壓力一般設定于12%,有些機則可設于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 ,按一般機臺而言,高壓位置機臺在出廠時都已作了設定,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,甚至于設在55%即可,如果是滑塊較多,原來生產時毛邊也較多,甚至于可設在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%.加熱工藝條件設定Heating technique parameter setting ,但卻必須遵循一個這樣的規(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 ,一般出于對機臺油路中的油封保護需要,油溫最好能控制在40度60度,以免油封長期高壓而變化,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 molding (加料)工藝條件設定Injection and plastic Techn
