吊扇后罩注塑模具设计
摘要
本文主要介绍的是吊扇后罩注塑模具的设计方法。首先分析了吊扇后罩制件的工艺特点,包括材料性能、成型特性与条件、结构工艺性等,并选择了成型设备。接着介绍了吊扇后罩注塑模的分型面的选择、型腔数目的确定及布置,重点介绍了浇注系统、成型零件、合模导向机构、脱模机构、定距分型机构以及冷却系统的设计。然后选择标准模架和模具材料,并对注射机的工艺参数进行相关校核。最后对模具的工作原理进行阐述,以及在安装调试过程中可能出现的问题进行总结、分析,并给出了相应的解决方法。
本文论述的吊扇后罩注塑模具采用三板式结构,即浇注系统凝料和制件在不同的分型面脱出,采用一模两腔的型腔布置,最后利用推板将制件推出。
