肥皂盒上盖的注塑模设计 摘要 注射成型是热塑性塑料成型的主要方法之一，可以一次成型形状复杂的精密塑件。塑料模具的发展是随着塑料工业的发展而发展的。近年来，人们对各种设备和用品轻量化要求越来越高，这就为塑料制品提供了更为广阔的市常 本课题主要针对肥皂盒上盖的模具设计，所用的塑料为ABS,是常见的日用品。通过对塑料制件进行工艺的分析和比较，最终设计出一副注塑模。该课题从产品结构工艺性，具体模具结构出发，对模具的浇注系统、模具成型部分的结构、顶出系统、冷却系统、注塑机的选择及有关参数的校核都有详细的设计，同时并简单地编制模具的加工工艺。通过整个设计过程说明该模具能达到此塑件所要求的加工工艺。根据题目设计的主要任务是肥皂盒上盖注塑模具的设计，也就是设计一副注塑模具来生产塑件产品，以实现自动化提高产量。针对塑件的具体结构，该模具是侧浇口的单分型面注射模具。通过模具设计表明该模具能达到盒盖的质量和加工工艺要求。 设计中参考了以往注射模具的设计经验，并结合制件性能，根据产品外形简化设计机构，并且运用AutoCAD、Solidworks等软件进行二维和三维的绘图，缩短了生产周期，获得良好的经济性能。 关键词：注塑模具；塑料；冷却 Abstract The i
