The sequence and temperature field of aluminum alloy gearbox shell during filling and solidification were simulated and analyzed by CAE simulation software,and the defects such as gas trapping and dispersed shrinkage were observed,and the reasons were analyzed.According to the results of simulation analysis,the related improvement of die casting process was proposed,that is,by increasing the number of diverting channels in the pouring system and optimizing the design of the overflow system.Finally,through actual production and X-ray detection,the defects were improved,which verified the feasibility of the scheme and provided a reference for casting qualified castings.
