摘要

采用PROCAST软件

对铝合金压铸成形工艺进行数值模拟

得到压铸过程中模具的温度场、应力场及模具的热疲劳分布云图。选取实际生产中容易出现热疲劳的两个工艺特征区进行了模拟结果分析

对比研究了"T"型浇注系统和"梳"型浇注系统

得出"梳"型浇注系统为该铸件较佳的浇注系统

验证了该优化设计对减少模具的热疲劳、提高模具使用寿命的可行性。

Abstract

Temperature field

thermal stress field and thermal fatigue distribution of the mould were visualized by the Procast software simulating forming process of aluminum alloy dome of coffee machine.Two typical processing feature regions in which thermal fatigue easily appeared were selected to simulate.The T-shape gating system and comb-shape gating system were analyzed comparatively.The results show that comb-shape gating system exhibits more desirable.The experimental results verify the feasibility of the optimized design for decreasing thermal fatigue and improving service life of the mould.
