肥皂盒的注塑模具设计 摘要 这次设计题目是肥皂盒注塑模具设计，用游标卡尺测绘这几何特征是弧和直线等简单的几何特征构成，初步确定了模具结构，型腔数目为1模2件，浇注系统是侧浇口等关键结构。设计难点是浇注系统的设计如何避免产品出现空洞；怎样确定合适的脱模斜度使模具容易取出，还有如何设计顶出系统而不破坏塑件等问题。我在图书馆和网上搜索，找到了分型面相关资料和浇注系统的概念和模具设计的原则，在老师的指导下通过使用二维软件和三维软件对分型面和浇注系统进行了设计并设计了顶出系统，调用了标准模架，最终确定了模具结构的排布。利用CAD，UG进行建模，总体方案设计；计算确定肥皂盒模具各个尺寸，最终画出了零件图和装配图完成了整个设计。 关键词:树脂制品；模具；推出机构；工艺计算 Abstract The graduatio
