Plastic mold design and manufacturing are closely related to plastic processing. The success or failure of plastic mold processing depends largely on the mold design effect and mold manufacturing quality, and the plastic mold design is based on the correct plastic product design.

　　 The structural elements to be considered in the design of plastic molds are:

Parting surface, that is, the contact surface where the concave mold and the convex mold cooperate with each other when the mold is closed. The selection of its location and form is affected by factors such as product shape and appearance, wall thickness, molding method, post-processing technology, mold type and structure, demolding method, and molding machine structure.

　　Structural parts, that is, sliders, inclined tops, straight top blocks, etc. of complex molds. The design of structural parts is very critical, related to the life of the mold, processing cycle, cost, product quality, etc. Therefore, designing the core structure of a complex mold requires a designer to have a higher comprehensive ability, and strive to be simpler, more durable, and more economical. Design.

　　The precision of the mold, that is, avoiding jams, precise positioning, guide posts, positioning pins, etc. The positioning system is related to the appearance quality of the product, mold quality and life. According to the different mold structure, different positioning methods are selected. The positioning accuracy control mainly depends on processing. The inner mold positioning is mainly considered by the designer to design a more reasonable and easy-to-adjustable positioning the way.
