摘要

以某型铝合金发动机缸盖为对象

对其快速砂型铸造工艺进行分析。根据铸件特点设计了顶注式与底注式两种浇注方案

通过UG NX进行三维建模后

运用ProCAST软件

对两种方案进行仿真对比

以对工艺方案进行优化。模拟结果表明

采用单侧底注式开设内浇道的浇注方案

在浇注温度为690℃

浇注速率为0.22m/s的条件下

生产出合格铸件。

Abstract

The rapid sand casting aluminum alloy cylinder head of the engine was conducted.According to the characteristics of cylinder head

the top pouring and bottom pouring gating were taken into account.Through the UG NX 3D modeling

two kinds of gating systems were simulated by the ProCAST software to optimize the pouring parameters.The results reveal that through designing the gating system with single side-bottom pouring at 690 ℃ and 0.22m/s

the satisfied aluminum alloy cylinder head can be produced

meeting the requirements.
