摘要

为了实现某铝合金零件的整体熔模铸造并获得高质量的铸件

运用ProCAST软件对其铸造过程进行数值模拟。通过对充型、凝固过程的分析

预测出缩孔、缩松形成区域。经过优化设计

在铸件底部进行增加水冷床装置

使原铸件缺陷位置发生改变

提高了产品的品质和合格率。

Abstract

In order to produce aluminium alloy castings with high quality by investment casting

the casting process was simulated by the ProCAST software.The shrinkage porosities（holes）were predicted by visualizing filling and solidification.Through the optimized design

with adding a water cooling bed at the bottom of the casting

the defect position in the initial castings was transferred

and the quality and yield rate of the castings were improved.
