Therefore, the mold industry has bee the foundation of the national economy work, called the mother of industry. Mould manufacturing technology, has bee a national product manufacturing technology of the important symbol. The plastic molding process and mould technology not only with the polymer materials synthesis technology improvement and innovation of molding machinery molding equipment, molding process of practice and progress, and along with the puter technology, the numerical simulation technology in the field of plastic forming and development peration. This article mainly described the design of injection mould helmet. Contents include the choice of materials and products of material properties of analysis, injection machine selection, gating system, forming zero A, cooling system and the design of corepulling mechanism etc. In addition, also including the mold CAD/CAM, and use the advanced software will its processing parts Delivery to the NC files. The paper emphasizes using modern puter aided design manufacture technology, using CAXA Pro/E, domestic and international famous software etc. both Ensure the quality of products, but also greatly improve the manufacturing productivity, shorten the cycle of product update. Through the graduation design, for me in the university learning stage of mould design aspects of knowledge is a good summary and consolidate, the peacetime learning is scattered knowledge achieved systematic application. Also found himself in some aspect of knowledge within a short, do owe the good review and understanding of mechanical manufacturing, processing technology is a systematic and prehensive understanding, reached the purpose of learning.
