摘要
利用ProCAST数值模拟软件对充型和凝固过程进行模拟,并预测铸件缩孔缩松缺陷,对于研究铸造工艺对金属型铝镁合金铸件质量影响具有重要的指导意义。本文就拉伸试样铸件设计了侧式正弦浇道和竖式直浇道两种不同浇注工艺,并且在充型温度场、凝固时间以及缩孔缩松缺陷预测等方面进行了数值模拟分析和结果对比,最后选用了竖式直浇道工艺进行模具设计制造和铸造。铸造表明,模拟结果合理,竖式直浇道工艺可以进一步改进。
The filling and solidification process of specimen castings were simulated using numerical simulation software ProCAST, and the shrinkage defects of the castings were predicted. It has very important guiding significance on studying the effects of metal mold casting technology on the casting quality of aluminum magnesium alloy. Two kinds of different casting technology for tensile specimens were designed, and the numerical simulation analysis and result comparison of filling temperature field, solidification time and shrinkage defect prediction were conducted. Finally, the vertical straight runner casting technology was adopted to conduct the mold designing, manufacturing and casting. The results show that the simulation result is reasonable and the vertical straight runner technology can be further improved.
