摘要
采用铸造模拟软件Procast对铝合金汽缸盖的消失模铸造进行了充型和凝固过程的模拟。分别从负压度、模样密度和浇注温度3个主要影响因素方面分析其规律,以充型过程平稳、凝固时间较短为目标,依据仿真结果分析铸造缺陷产生的原因,优化浇注系统和铸造工艺。
Using Pro CAST software to simulate and optimizate filling and solidification process of lost foam casting for aluminum cylinder head,the three main factors were analyzed in the aspects of the bubble shape density,pouring temperature and negative pressure taking smooth filling process and shorter solidification time as the goal.According to the simulation results,the mold filling process is stable and the solidification time is short.
