内容简介：

盒盖注塑成型工艺与模具设计摘要：塑料注射的设计过程，其中的设计内容有零件的工艺性编制：塑件的工艺性分析、塑件的体积和质量计算及注射机参数的确定；结构设计：分型面选择、型腔数确定、型腔的排列方式、浇口设计、侧向分型抽芯机构设计、推出及复位机构方式确定；型芯、型腔尺寸计算；模具加热和冷却系统计算；模具闭合高度确定；注射机有关参数的校核。如此设计出的结构可确保模具工作运用可靠。最后对模具结构与注射机的匹配进行了校核。并绘制了一套模具装配图和零件图。关键词：模具注射机注射Lifted the lid of injection molding process and mold designAbstract: the design of plastic injection process, the manufacturability of the parts design content: the volume of the manufacturability analysis of plastic parts, plastic parts and confirmed the parameters calculation and injection machine quality; Structure design, selection of parting surface, cavity number, cavity arrangement, the gate design, side parting core-pulling mechanism design, launch and reset institutions to determine; Core and cavity size calculation; Calculating mould heating and cooling system; Die closed height determine; Injection machine related parameters of checking.
