CRH380A箱盖低压金属型铸造工艺研究

Study on Low Pressure Die Casting Process of the Top of CRH380A Gear Box

基于Magma模拟软件和工艺试制结果,优化了CRH380A箱盖低压金属型铸造工艺,分析了模具温度、充型速度和浇铸温度对铸件凝固过程的影响,得到了可行的CRH380A箱盖低压铸造工艺并获得了合格样件。本文也为其他铝合金铸件低压金属型铸造工艺研究提供了有益的参考。

In this paper, based on the cast simulation soft Magma and the results of producing process, the low pressure die casting prneess of the top of CRH380A gear box was optimized. The effeels of the die temperature, filling velocity and easting temperature on the solidification process were analyzed. The feasible low pressure die casting process as well the qualified top of CRH380A gear box was obtained. It provides the valuable reference for the research of low pressure die casting proeess of other Aluminum cast.
