摘要

运用ProCAST软件对铝合金化油器中体压铸件进行压铸模拟仿真。通过分析压铸过程中金属流体的流动场、温度场以及预测缺陷的分布和含量

优化了压铸工艺参数:压射速度为2.5m/s

模具预热温度为210℃

浇注温度为620℃

内浇口厚度为2.5mm。通过压铸试验

得到了合格的化油器中体压铸件。通过金相观察

证实了模拟结果的准确性。

Abstract

Filling process of die casting aluminum alloy carburetor midbody was simulated by the ProCAST software.By analyzing temperature field and flow field in die-casting process of aluminum carburetor and observing distribution and volume of predicated flaws

the optimized parameters of die-casting process were presented as follows:the injection speed of 2.5m/s

mold preheating temperature of 210℃

pouring temperature of 620℃and ingate thickness of 2.5mm.Through adopting the optimized parameters

the qualified carburetor midbody was produced successfully.Microstructural observation reveal

that the simulated defects are well in agreement with the practical ones.
