Abstract: This project belongs to electrical components as shown in three-dimensional modeling data, the product is the main component parts. Part is the use of plastic molding, the appearance of high surface quality requirements, the shape does not allow leaving obvious traces of graduation integrated practice, you can learn a special part of the release structure, the subject meet graduation requirements. Focus on solving the mold structure design is reasonable, the exhaust of the better, as far as possible to achieve the accuracy required after molding requirements, to consider the deformation of the molding process. Production program is: Nissan 200-800 pieces belong to the production, requiring a mold one. After completion of the project according to business requirements and design cold runner mold, as an important reference for technological transformation of enterprises technical information. According to the design assignments requiring students to collect plastic material molding process parameters as well as relevant information, apply their knowledge and skills to solve the production of molded plastic material aspects of the practical problems.
Complete plastic molding process design and mold design and manufacturing processes, etc.: learning through graduate design can UG simple three-dimensional modeling, preparation of working parts of the machine mold processing technology is to understand the mold machining processes, processing technology, learn to analyze OK gating system and parting surface, mold flow analysis to determine the best casting system. Complete set of two-dimensional, three-dimensional mold parts diagram, assembly diagrams, complete instructions, and finally through graduation reply.
