In the domestic market, plastic mold injection mold greatest demand, which is focused on the development of plastic mold. Injection molding is an important method of plastic molding, it is mainly suitable for thermoplastic molding, forming a complex shape can be precision plastic parts. The subject is flowers covered plastic molding process and mold design, injection mold knowledge as the basis to explain the plastic injection mold design process. (1) through the use of plastic mold design guidelines, mechanical drawing, interchangeability and measuring technology 673A mechanical principle and parts, mold materials and heat treatment, mold manufacturing process, the plastic molding process and die design and other aspects of the necessary basic knowledge and expertise, plastic mold design analysis and solve problems, to further consolidate and deepen the knowledge learned to open up (2) The design of injection mold design flowers cover plugs, the use of UG software was solid modeling plastic parts, plastic parts for the structure analysis process. Clear design ideas, determine the injection molding process and the various specific parts of a detailed calculation and verification. Such a structure designed to ensure reliable use of mold work to ensure coordination with other components. Finally, draw a mold assembly drawings and parts drawing with autoCAD (3) by calculating, mapping and the use of technical standards, specifications, design manual and other relevant design sheets, plastic design comprehensive basic skills training, and lay a good foundation for the practice of graduation design. (4) This paper cup through the juicer barrel injection mold design, to consolidate and deepen the knowledge, and achieved satisfactory results, to achieve the desired design intent.
