镁合金电机端盖压铸模具设计CAD CAE——毕业论文.docVIP

山东科技大学学士学位论文

摘要

本文从国内镁合金压铸模CAD/CAE技术与国际先进技术水平的差距和急需解决的问题着手，提出了镁合金压铸模集成CAD/CAE的思想，并结合实际压铸模具设计的范例，实现了镁合金压铸件电机端盖体压铸模CAD/CAE的集成。

从压铸过程的数学物理模型出发，阐述Anycasting软件进行压铸过程数值模拟的实现方法，并利用Anycasting对镁合金电机端盖体零件进行压铸过程流场、温度场数值模拟，分析铸件在压铸过程中可能出现的缺陷，以此来指导压铸模具浇注排溢系统的优化设计。基于Anycasting模拟得到的结果，进行压铸模具的整体结构设计，借助三维建模软件Pro/E进行总装图及主要零部件图的设计。电机端盖压铸模具设计主要包括分型面、浇注系统、排溢系统、成形零件、辅助零件、结构零件等的设计，及成形零件工作尺寸等的计算。
