介绍塑料模具注射成型设计过程注意事项,分析塑件工艺性,塑件工艺分析以塑件制作要求和生产要求、塑件品种结构特点、塑件尺寸精度分析、塑件表面质量分析、塑件结构工艺性分析、塑件使用性能,然后选择参数符合的注塑机,确定注塑机,进行模具注射结构设计,确定分型面,确定型腔数目及型腔排列及浇注部位安排、成型结构设计、抽芯机设计、推出机设计、排气设计、冷却设计、标准模架定位,最后对成型工件数据计算,订制工艺参数,注射成型是最重要的塑料成型方法之一,如何提高注射成型技术水平,生产出高精度的塑料制品,除应考虑一般模具设计事项外,还要特别考虑成型收缩率误差、成型变形、脱模变形。
Plastic injection mold design process considerations, analysis of plastic parts technology, plastic parts process analysis to plastic parts production requirements and production requirements, plastic parts structure characteristics, plastic parts dimensional accuracy analysis, plastic parts surface quality analysis, plastic parts structure Process analysis, the use of plastic parts, and then select the parameters of the injection molding machine to determine the injection molding machine, mold injection structure design, to determine the parting surface, determine the number of cavities and cavity arrangement and pouring site arrangements, design of the structure, pumping Core machine design, the introduction of machine design, exhaust design, cooling design, the standard mold positioning, the final calculation of the molding workpiece data, custom process parameters, injection molding is one of the most important plastic molding methods, how to improve the level of injection molding technology , To produce high-precision plastic products, in addition to considering the general mold design issues, but also special considerations molding shrinkage error, forming deformation, demoulding deformation.
