塑料盆注塑模具设计
摘要
模具是工业生产中的重要工艺装备,模具工业是国民经济各部门发展的重要基础之一。随着机械工业,电子工业,航空工业,仪器仪表工业和日常用品工业的发展,塑料成型制件的需求量越来越多,质量要求也越来越高,就要求成型塑件模具的开发,设计与制造的水平也必须越来越高。
本设计详细的论述了塑料盆注射模具设计及其工艺分析。首先对塑料盆的制件结构,所用塑料的材质特点及其成型工业进行了充分分析,对塑料盆的整个成型过程有充分了解,为下一步的模具设计提供参考依据,保证模具结构设计的合理性。然后确定注射机的型号,模具的分型面和型腔的数量,针对塑件所设计的型芯与型腔,确定其合理的浇注系统与排溢系统,再后就是设计温度调节系统,合模导向机构,推出机构。完成以上设计,选取合理的模架,对模具主要零件的制作进行工艺分析,最后完成整个模具设计。
本设计使用UG三维软件对塑件进行三维建模,模具分型及其所有机构的设计,通过UG的制图模块导出CAD文件,同时使用AutoCAD进行必要的二维修改,制图,最终完成整个模具设计。
