摘要 本课题主要是针对影响防尘罩的模具设计,通过对塑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,同时并简单的编制了模具的加工工艺。通过整个设计过程表明该模具能够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音响注塑模具的设计。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。针对音响盒盖的具体结构,该模具是点浇口的双分型面注射模具。由于塑件内侧有四个小凸台,无法设置斜导柱,固采用活动镶件的结构形式。其优点在于简化机构,使模具外形缩小,大

大降低了模具的制造成本。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。
