摘要
采用铸造模拟软件ProCAST对腔深、壁薄的A356合金的"筒壳"铸件进行模拟分析。通过对其压铸过程中的温度场进行数值模拟、分析,预测缩孔缩松所在的位置及大小。优化出最佳工艺参数:浇注温度为590℃,压射速度为5 m/s,模具温度为220℃。在此工艺条件下A356半固态浆料充型平稳,温度场分布均匀,无飞溅卷气和浇注不足等缺陷,在实际生产中获得了质量完好的铸件,验证了该工艺参数。
The die cast ＂barrel shell＂ casting with deep cavity and thin wall was simulated by casting simulation software ProCAST. By making casting simulation on casting process and temperature field, the location and sizes of shrinkage and dispersed shrinkage were forecasted. The optimized parameters are： pouring temperature 590 ℃, injection speed 5 m/s, mold temperature 220 ℃. Under this process, semi-solid slurry mold filling is stable, temperature field is uniform and there were no casting defects such as splash air entrapments and misnm. The process parameters were proved by obtaining perfect part quality in actual production.
