Technological Parameters Optimization of Die Casting of Aluminum Alloy Projectile Base Rotor Based on the AnyCasting

结合铸造生产实际,合理设计了铸件的结构。采用AnyCasting数值模拟软件,用正交试验方法分析了铝合金弹底转座压铸工艺过程中浇注温度、充型速度以及模具预热温度对铸件质量的影响规律。结果表明,模具预热温度对铸件质量的影响最大,浇注温度次之,充型速度最小,最优的工艺参数是浇注温度为650℃、充型速度为0.25 m/s和模具预热温度为180℃。同时,在最优工艺参数的基础上,结合实物验证了模拟的可靠性,并观察了铸造铝合金的微观组织。

According to the practice of casting production, the casting structure was designed reasonably. By using AnyCasting numerical simulation software, the influence of casting temperature, filling speed and preheating temperature on casting quality was analyzed by orthogonal test. The results show that the preheating temperature of the mold have the greatest influence on the casting quality, followed by the pouring temperature, and the filling speed is the smallest. The optimal process parameters are the pouring temperature of 650 ℃, the filling speed of 0.25 m/s and the preheating temperature of the mold of 180 ℃. At the same time, on the basis of the optimal process parameters, the reliability of the simulation is verified by combining with the real object, and the microstructure of the cast aluminum alloy is observed.
