摘要

对某油底壳压铸成形过程中铝合金液流动充型及铸件缺陷分布状态进行了数值模拟

分析了试模与试生产阶段各种缺陷产生的原因

通过对浇注系统与排气系统等进行了改进

提高了压铸件的品质

减少了模具的开发周期。结果表明

合理的浇注、排气系统与适当的加工余量是获得高品质压铸件的关键。

Abstract

Filling and defects distribution in the die casting aluminum alloy sump were predicted

and origination of the defects generation during trial mould and trial production process was described.The gating and exhausting system was modified based on result analysis

so the sump quality was improved with decrease of mould developing cycles.The results reveal that they are the key factors

such as rational pouring parameters and exhausting system as well allowance

for obtaining high quality aluminum alloy sump.
