山東模具製造廠家在分型麵的選擇上的（de）選擇會影響開模後注塑件是留在動模腔內還是在定模（mó）腔內，進而影響注塑件能否成型（xíng）。那（nà）麽在選擇注塑模具分型麵時要注意什麽要點？

　　Shandong mold manufacturers in the selection of parting surface choice will affect the injection parts after opening the mold is left in the moving mold cavity or in the fixed mold cavity, and then affect the injection parts can be formed. So in the choice of injection mold parting surface should pay attention to what points?

　　脫模成功影響模具型腔的可加工性，分型麵是否會（huì）出現“飛（fēi）邊”或分（fèn）型麵的痕跡是否會影響注（zhù）塑件的尺（chǐ）寸、形狀、壁厚、模具結（jié）構、模具排氣（qì）和薄膜模具。因此，在選擇分型麵時，要綜合考（kǎo）慮各種影（yǐng）響因素、條件和要求，合理選擇分型麵。

　　The success of demoulding affects the machinability of the mold cavity, whether the parting surface will appear “flying edge” or the mark of the parting surface will affect the size, shape, wall thickness, mold structure, mold exhaust and film mold of the injection parts. Therefore, in the selection of parting surface, it is necessary to consider all kinds of influencing factors, conditions and requirements, reasonable selection of parting surface.

　　一般情況下，注塑件應留（liú）在動模腔（qiāng）內，這樣更便（biàn）於注塑件的脫（tuō）模；應避免“障礙體”的阻礙，避免運動幹擾，以利於注塑件的脫模和模腔的加工（gōng）；應設置在不顯眼且易於去除飛邊、毛刺和易於加工的位（wèi）置；應設置在圓（yuán）弧R的切點以（yǐ）外的位置，無凹陷和（hé）圓弧。

　　In general, the injection parts should be left in the moving mold cavity, so that it is more convenient for the demoulding of injection parts; Should avoid the obstruction of “obstacle body”, avoid movement interference, in order to facilitate the demoulding of injection parts and mold cavity processing; Should be set in unobtrusive and easy to remove flaking, burr and easy to process position; It should be set outside the tangent point of arc R, without sag and arc.

　　應考慮（lǜ）澆口位置及其形狀（zhuàng）的設置；有利於澆注（zhù）係統和排氣係統（tǒng）的布置；不影響注塑件的尺寸和精度；應（yīng）考（kǎo）慮塑料的性能和填（tián）充條件；應考慮成型的（de）加工性和效（xiào）率；模具結構簡單，使用方（fāng）便，可靠。

　　The locations and shape of the gate should be considered; Conducive to the layout of gating system and exhaust system; Does not affect the size and precision of injection parts; The properties and filling conditions of plastics should be considered; The processability and efficiency of molding should be considered; The mold structure is simple, easy to use, reliable.

　　由於分型麵（miàn）受塑件在模具中的（de）成型位置、澆注係統的設計、塑件的結構可（kě）製造性和精度、鑲件的位置和形狀以及成型方法等多種因素的影響。頂（dǐng）出、模具的製（zhì）造、排氣、操作工藝等因素，因此在選（xuǎn）擇分型麵時，應進行綜合（hé）分析比（bǐ）較，從幾種方案中（zhōng）選擇更合理的方案。

　　Because the parting surface is affected by the molding position of the plastic parts in the mold, the design of the pouring system, the manufacturability and precision of the structure of the plastic parts, the position and shape of the insert and the molding method and other factors. Ejecting, mold manufacturing, exhaust, operation process and other factors, so in the selection of parting surface, should be a comprehensive analysis and comparison, from several programs to choose a more reasonable program.
