Abstract：Aluminum alloy motor shell is complicated in structure and difficult to cast.This paper introduces the structural characteristics of the motor shell and identifies the common casting defects of the motor shell.On this basis,the typical sand casting process scheme of motor shell is discussed.This paper analyzes the feasibility of gravity casting,low pressure sand casting,low pressure casting with over flow,and tilt casting,and focuses on the gate design and riser design of low pressure sand casting.The research shows that the above four casting methods can be used in the production of motor shell,the specific process selection depends on the characteristics of product structure,and the feasibility of the process is evaluated by computer simulation.This paper also discusses the application of computer simulation technology in the development of casting process of motor shell.
