Abstract：In view of the structural characteristics and performance requirements of large aviation thin wall aluminum alloy castings,the principle and advantages of low pressure casting process were utilized to solve the casting process problem of large aviation aluminum alloy castings by means of casting simulation software.Through the analysis of casting structure and casting principle,the design of low pressure casting mold was carried out.The results show that the casting mold design and casting process are verified by using casting simulation software and process test,and the production process and process parameters of low-pressure casting are determined.
