Meanwhile to modelled the formed craft and the mold takes shape the structure to model a quality the influence to carry on the analysis. In the design process, first to models to carry on the craft analysis, understood models a material, the shape, the size and the precision request, the reference craft feasibility, the craft plan which the choice answers the purpose. Then I to compose according to the design request cast the mold to take shape the spare part, pour the system, the guidance organization, the drawing of patterns structure, lateral dividing with pull out the core organization, heat up with the cooling system, the exchaust gas system and other spare parts carry on the design. In mold design process many considerations mold structure adjustment, easy replacement and mold cost. Embarks from the control workpiece size precision, molded each main dimension to the computer pressed key note to carry on the theoretical calculation, by determined each work components the size. After the mold components design finished, has carried on the examination to the important work structure and the components. After the examination had finished to mold installment and debugging. Designs from the mold to the spare part processing craft as well as the assembly craft and so on carries on the detailed elaboration, and carries on various components using CAD the design.Key word: Craft analysis; Models to take shape; Pours the system; Mold structure; Examination
