摘要

对铝合金发动机后端盖进行了压铸充型凝固过程数值模拟，对可能产生缩孔、缩松的部位进行预测。分析了充型、凝固过程，对冷却水道进行优化，采用正交试验优化了压铸工艺参数：浇注温度为680 ℃，压射速度为4 m/s，模具预热温度为220 ℃。用优化后的方案进行压铸生产和检测，结果表明压铸件品质得到显著提高。

Abstract

The numerical simulation of die casting mold filling and solidification process of the rear end cover of an aluminum alloy engine was carried out， and the possible shrinkage cavity and porosity were predicted. The filling and solidification were analyzed， and the cooling channel was optimized. The optimal process parameters were determined by orthogonal test： pouring temperature of 680 ℃， injection velocity of 4 m/s， preheating temperature of 220 ℃.The optimized scheme was used for die casting production and inspection.The test results reveal that the quality of die casting is significantly improved.
