山东模具制造厂家在分型面的选择上的选择会影响开模后注塑件是留在动模腔内还是在定模腔内，进而影响注塑件能否成型。那么在选择注塑模具分型面时要注意什么要点？
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?
脱模成功影响模具型腔的可加工性，分型面是否会出现“飞边”或分型面的痕迹是否会影响注塑件的尺寸、形状、壁厚、模具结构、模具排气和薄膜模具。因此，在选择分型面时，要综合考虑各种影响因素、条件和要求，合理选择分型面。
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.
一般情况下，注塑件应留在动模腔内，这样更便于注塑件的脱模；应避免“障碍体”的阻碍，避免运动干扰，以利于注塑件的脱模和模腔的加工；应设置在不显眼且易于去除飞边、毛刺和易于加工的位置；应设置在圆弧R的切点以外的位置，无凹陷和圆弧。
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.
应考虑浇口位置及其形状的设置；有利于浇注系统和排气系统的布置；不影响注塑件的尺寸和精度；应考虑塑料的性能和填充条件；应考虑成型的加工性和效率；模具结构简单，使用方便，可靠。
The location 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.
由于分型面受塑件在模具中的成型位置、浇注系统的设计、塑件的结构可制造性和精度、镶件的位置和形状以及成型方法等多种因素的影响。顶出、模具的制造、排气、操作工艺等因素，因此在选择分型面时，应进行综合分析比较，从几种方案中选择更合理的方案。
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.
