摘要

利用ProCAST有限元分析软件并采用带压室的流态分析对压铸铝合金变速箱体压铸参数进行可视化调节，更能接近实际生产环境。在软件中进行不同参数试验，得出最佳低压速度为0.2 m/s、高速切换点为630 mm、高压速度为5 m/s。将这些参数在32 000 kN布勒压铸机进行试验验证，发现压铸出的变速箱体铸件外观品质良好，没有冷隔、气孔等缺陷，用X射线进行探伤，铸件内部没有观察到缩松、缩孔等缺陷。

Abstract

ProCAST software with pressure chamber flow analysis was used to visually adjust the die casting parameters

which was closer to the actual production environment. Experiments with different parameters in the software was carried out. The results show that the optimized processing parameters are presented as follows: low-pressure speed of 0.2 m/s

the high-speed switching point of 630 mm

and the high-pressure speed of 5 m/s. The parameters was verified by a 32 000 kN Buhler die-casting machine

and results reveal that the die-cast gear box presents the satisfeid appearance

and absence of defects such as cold shut and pores can be observed. X-ray detection shows that absence of shrinkage holes and other defects can be observed inside the castings.
