摘　　要：为优化汽车发动机缸盖金属型重力铸造工艺参数,数值模拟了不同浇注温度、时间以及模具温度条件下铸造的汽车铝合金发动机缸盖产品的合格率。采取顶注方式可以降低缩松倾向,随浇注温度和模具温度的提高,缩松缺陷面积逐渐减少。采用优化工艺方案生产的铝合金缸盖成品率达到98%以上。To optimize the casting process parameters for automobile engine cylinder in metal gravity, the pass rate of automotive engine cylinder head products of aluminum alloy was simulated under the conditions of different pouring temperature, time and mold temperature. The results show that the top injection mode can reduce the tendency of shrinkage porosity, with the increase of pouring temperature and mold temperature, shrinkage defect area is gradually reduced. Using optimized process, the pass rate of the produced aluminum alloy cylinder head castings can be more than 98%.
