The subject is about the design of Aluminum shell mold and process analysis. This paper has introduced the current situation of the modern mould manufacturing technology and developing direction, have proved especially that the aluminum alloy chassis parts die casting design process of the mould . It mainly since products craft of chassis analysis (mainly including drawing of patterns slope, wall thick, hole, size precision and surface roughness , shrinking rate ,etc.), sureness of the shaping scheme, exertion and fixing of the injecting machine, Non-ferrous metal casting molds of several big analysis and design of system (pour system , shaping spare part , cooling system , exhaust system , guidance system ,etc.) of mould, the respects , such as check of different technical data ,etc. set out, the detailed introduction injects several questions in the design
