摘要

采用数值模拟方法

模拟了缸体件的充型及凝固过程

得到了速度场、温度场的分布和变化规律。结果表明

浇注温度为620℃

模具预热温度为180℃

压射速度为4m/s时

生产的铸件品质较好。通过试验验证

模拟结果与实际生产基本一致。

Abstract

Filling and solidification of die casting cylinder were simulated by numerical simulation

and the distribution and change of temperature field and velocity field were visualized.The desirable cylinder quality can be obtained with pouring at 620 ℃ and pre-heated mould at 180 ℃ as well as filling at 4 m/s.The experimental results are well in agreement with simulated ones.
