摘要

用Solid Edge软件对铝合金梯级及浇注系统进行三维建模

选取9组工艺参数

用ProCAST软件对梯级的三维模型进行网格划分

然后对梯级的充型和凝固过程进行模拟

并对梯级可能存在的缺陷进行预测和分析

最终确定最优工艺参数。当模具预热温度为190℃

铝合金浇注温度为620℃

压射速度为5m/s时效果最好。

Abstract

3 D model of the aluminum alloy stair with gating system was established by Solid Edge software.Through selecting nine sets of parameters and applying the ProCAST software to enmesh grids of the 3 D model of the stair

the filling and solidification process of the stair were simulated

and the defects in the stair were predicted and analyzed.Finally

the appropriate processing parameters were determined as follows:preheating mould at 190℃and pouring liquid alloy at 620℃ with injecting velocity of5 m/s.
