Design of die security 86 panel process and injection
Abstract: This topic belongs to the electrical parts of three-dimensional modeling data as shown in the figure, the product is a main part of accessories, is the use 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, can learn the demoulding structure of special parts, this subject with graduation the 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. Programme for the production of 200800: Nissan, mass production to a mold, a. After the completion of the project according to the design requirements of the cold runner mould, as an important reference data of the technical transformation of enterprises. According to the design task assignment, molding process parameters require students to collect plastic materials and relevant materials, the application of knowledge and skills to solve practical problems in production of plastic material forming .
Complete the plastic molding process and mould design and manufacturing process: through graduation design learning, can UG three-dimensional modeling simple, mechanical processing work parts for mould is, understand the process, the mold machining process, learn to analyze and determine the gating system and the parting surface, the mold flow analysis, to determine the optimal gating system. The complete two-dimensional, three-dimensional mold parts diagram, assembly drawing, complete specifications, the graduation reply.
