Distance of knocking out longer 12cm than the vertical thickness of Back 頂退包括兩個(gè)過(guò)程與頂落的過(guò)程基本一致,頂退的終點(diǎn)應(yīng)預(yù)留13cm的空間, same as knocking out, ejector back includes 2 protect the ejector oil jar, it should make a 13mm distance in the ending point of ejector ,單次頂及頂針停留的選擇,機(jī)械手取產(chǎn)品,脫模順利的情況都采取多項(xiàng),為了頂針油缸 壽命的延長(zhǎng),多次頂就以不超過(guò)三次為宜,頂針停留一般用在頂針帶著產(chǎn)品退回有可能對(duì)增品產(chǎn)生損傷的模具,同時(shí)為配合機(jī)械手使用, way of knocking out includes knocking out once, Knocking out repeat and ejector product by manipulator or take product easy, it should select knocking out longer the work time of ejector oiljar, times of knocking out lower 3 delay used when product will be damaged if ejector back or suit Molding time setting 在保證產(chǎn)品質(zhì)量的前提下,周期時(shí)間是越短越好,周期時(shí)間又包括如下幾項(xiàng):射膠時(shí)間,保壓時(shí)間,熔膠時(shí)間,冷卻時(shí)間,頂出時(shí)間,鎖模低壓時(shí)間,甚至乎關(guān)系到時(shí)間因素的還有還開(kāi)模與鎖模, time should shorter on condition that product quality time includes: injection time , holding pressure time, plastic time, cure time, knocking out time and mold protect mold opening closing sopeed and knocking out speed affect ,一般看起來(lái),射膠時(shí)間越長(zhǎng),產(chǎn)品越飽和,但我們?cè)谥v求質(zhì)量時(shí),同時(shí)也須考慮產(chǎn)能,更何況,射膠時(shí)間過(guò)長(zhǎng),有可能會(huì)造成產(chǎn)品過(guò)于飽滿而尋致粘模頂?shù)淖冃螀沾缙蟮纫幌盗袉?wèn)題,故我們?cè)谠O(shè)置射膠時(shí)間時(shí)應(yīng)綜合考慮, time consists holding pressure injection time, fuller product, we should consider production quantity when we suit for injection time too long, it may cause a series of defects suck as flash all sorts of factors should be considered, injection time should be shout if quality suit for ,背壓設(shè)定的大小,但有一點(diǎn), time depends on plastic speed and screw back pressure, but plastic time must shorter than cure :冷卻時(shí)間的長(zhǎng)短直接影響到成型的周期,冷卻時(shí)間越長(zhǎng),成型時(shí)間就越長(zhǎng),造成產(chǎn)能就越低,故我們?cè)谠O(shè)定高壓冷卻時(shí)間時(shí),只要能保證到產(chǎn)品成型順利,不會(huì)直接影響到變形等問(wèn)題, time: Cure time affects molding cure time, longer molding cycle, lower production it sets cure time short on condition that product molding succed and can’t deformation..,我們的頂出時(shí)間一般是與機(jī)械手配合為宜,半自動(dòng)生產(chǎn),如因頂針退回會(huì)導(dǎo)致產(chǎn)品掉落或卡緊,而取不下產(chǎn)品, PCE pany, for using manipulator in abundence , knocking out time suitsmanipulator, Knocking out delay keeps second when using manipulator fullmanipulator, knocking out delay keeps about 5 second when using manipulator semimanipulator and product will fall or can’t be taken off if ejector ,模具安全起很大作用,配合好模具低壓位置和低壓壓力的調(diào)整,低壓保護(hù)的時(shí)間應(yīng)取13秒,保護(hù)時(shí)間越短, protect is very important for safety and protect mold, Mold protect time should adjust within 13 second suit low

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HighspeedmidspeedLow pressure high pressure speed鎖模條件設(shè)定:Mold closing parameter setting1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/,但卻必須遵循一個(gè)這樣的規(guī)則,即由射口筒到In
