摘要
通过利用数值模拟软件对压铸机活塞铸件的铸造过程进行模拟,根据模拟结果分析了活塞铸件的充型温度场和速度场、凝固过程、凝固温度场、缩孔缺陷及应变情况,从而对其铸造工艺方案进行了优化,并通过模拟结果对比分析得到了最佳铸造工艺参数。
The casting process of piston castings for die-casting machine was simulated by using numerical simulation software.According to the simulation results,the temperature field and speed field of the mold filling,solidification process,solidification temperature field,shrinkage defects and strain situation of piston castings were analyzed,so that the casting process scheme was optimized,and the best casting process parameters were obtained by comparing the simulation results.
