Abstract

 At present, the design of molds, particularly the design of die-casting molds, plays an increasingly important role in modern manufacturing industry. Die-casting is an effective, efficient and promising method of casting. Under the impetus of high-tech , die-casting will further expand its scope of application, in national economic development , it will play an increasing role. Compared with other methods, it has a high dimensional accuracy, high strength, smooth roughness and high productivity.
Based mainly on parts of the design integrity of the structure and size, it scheme out the required spare parts. Design elements include: design of gating system, forming part design, core-pulling mechanism design, the ejector design and the mold body structure design. According to the shape of features , parts size and accuracy, the author selected the appropriate die casting machine, through the exactly calculate and consult design handbooks, confirm the size and accuracy of the forming part and mold body structure, it also makes particular instruction on the material selection and the requirements of the heat treatment, with theoretical basis, plotting out pictorial drawing and casting drawing of the parts by using computer software to ensure the manufacture of die-casting die.
