1、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塑件。圆珠笔是我们日常不可或缺的文具之一，圆珠笔笔套作为保护笔尖的部件同样有着重要的作用和实际的意义。本课题设计了一副圆珠笔笔套的注塑模，模具采用一模八穴非平衡式布排，浇注系统采用侧浇口，笔套外形复杂，采用斜导柱侧向分型，并用autoCAD绘制了一套模具装配图和零件图。关键词：注塑模；一模八穴；非平衡式；侧浇口；斜导柱；侧向分型目录摘要································································

8、0％。现在，这3个省份的不少企业已意识到塑模业的无限商机，正积极组织模具产品的开发制造。塑料制品在汽车、机电、仪表、航天航空等国家支柱产业及与人民日常生活相关的各个领域中得到了广泛的应用。塑料制品成形的方法虽然很多，但最主要的方法是注塑成形，世界塑料模具市场中塑料成形模具产量
