摘要

主体壁厚为3mm的铝合金壳体铸件

成形比较困难。因此

设计两种方案

利用3D打印砂型进行低压铸造浇注验证。结果表明

选择合适的浇注位置并设计合理的浇注系统

有利于薄壁铸件的成形

并利用CAE软件模拟优选出合理的铸造工艺方案。

Abstract

It is difficult to manufacture wall thickness of 3 mm and complex shape aluminum alloy.castings 3DP sand mould combined with low-pressure casting was adopted to produce the aluminum alloy housing with two design schemes.The results reveal that it is beneficial for forming thin-walled aluminum alloy housing through selecting rational pouring position and designing proper gating system.Meanwhile

the optimized process was determined based on the CAE analysis.
