Abstract: the product is a part of automobile handle. Products with high accuracy requirements of molding to meet the functional requirements of products, ask students to use the basic theory, methods and skills of the professional knowledge and related professional, comprehensive use, according to the structure of the product and the combination of product quality requirements, designed in line with the actual production levels, mould structure with advanced, reasonable process, high economic performance, manufacturing process and formulate the main parts, to solve specific problems of material forming process. Master the basic process of the plastic mold design, improve the computer aided design and consulting relevant literature, the basic skills of design data, standards and norms, completed the graduation design calculation and manual tasks. The product is made of plastic molding, the appearance of high surface quality requirements, the shape is not allowed to stay clear traces, students in the process of comprehensive graduation practice, demoulding structure can learn the special parts, this paper meet the graduation design requirements. To solve the die structure design is reasonable, the exhaust is better, as far as possible to achieve the requirements after the molding accuracy requirements, to consider the deformation in the process of forming.
Key words: mechanical design; injection mould; CCC cover.
