In this paper,the optimization of key parameters of the extrusion casting process of aluminum alloy auto parts and its influence on the performance of the parts are studied.Through the orthogonal experimental design,the influence of process parameters such as extrusion speed,mold temperature and liquid metal temperature on the mechanical properties,internal defects and surface quality of parts was studied.The results show that by appropriately increasing the extrusion speed and liquid metal temperature,and reducing the mold temperature,good surface quality can be obtained.,while ensuring the mechanical properties of the parts,and internal defects can be minimized.This study can provide theoretical guidance and data support for the optimization of the extrusion casting process of aluminum alloy auto parts.
