We make the plastic parts in the structure design, plastic molding process analysis, plastic mold, plastic mold parts of the digital design and material selection, heat treatment, plastic mold manufacturing, comprehensive training and information retrieval, English translation and so on, in order to shorten the work period to lay a solid foundation for the design of the main content is as follows: (1) to clear plastic parts design requirements: read the product parts, products from plastic, plastic parts shape, size precision, considering the feasibility and economy of the injection molding process of all aspects of the surface roughness when necessary, to explore the possibility of modifying the material type and structure of plastic parts and products the designer. (2) using UG and CAD software to complete the mold design: parting surface should be in shape to meet the requirements of maximum contour, the appearance quality of plastic parts. (3) die structure design: molding position and parting surface selection; determine the mold cavity number, cavity arrangement and runner layout and gate location design; structure design of die parts; ejection mechanism design; exhaust system design. (4) to determine the overall size of the mold and the selection of mold: mold has been gradually standardized, the selected frame, complete structure design based on the above preliminary draw mold parts mold. (5) drawing die assembly drawing and parts drawing: drawing die drawing must comply with the national standard of mechanical drawing, mold assembly drawings should include the necessary dimensions, such as the closed mold size, shape size, feature size, assembly size, limit the size and technical conditions, preparation of parts list etc..
