Mold design and manufacture are closely related to plastic processing. The success or failure of plastic processing mainly depends on the effect of mold design and the quality of mold manufacturing. Plastic Mold design is based on correct plastic Product Design. The structural factors that need to be considered in the design of plastic molds are as follows: 1. Parting surface, that is, the contact surface where the mold and stamping form cooperate with each other when the mold is closed. The location and shape are selected according to factors such as product shape and shape, wall thickness, molding method, post-processing process, mold type and structure, peeling method, molding machine structure, etc. Frame, that is, the sliding block, inclined top, straight top block, etc. of complex molds. The design of structural parts is related to the life of the mold, processing cycle, cost, product quality, etc., and is very important. Therefore, designing a complex mold core structure requires a high degree of comprehensive ability of the designer. Pursue the design that is as simple, durable and economical as possible. Mold accuracy, namely pickup, positioning, guide post, positioning pin, etc. The positioning system selects different positioning methods according to the appearance quality of the product, the quality and life of the mold, and the structure of the mold. The positioning accuracy control mainly relies on processing, and the internal mold positioning is mainly considered by the designer, and a more reasonable and easier to adjust positioning method is designed. 2. The main channel system, that is, the feeding channel from the machine nozzle to the cavity, including the main channel, the runner, the gate and the cold material hole. In particular, the choice of gate location should help the molten plastic to fill the cavity with good flow, and the solid runner and gate cold material attached to the WIP can be easily ejected and removed from the mold ( Except for hot runner molds). Various factors that affect the dimensional accuracy of products, such as plastic shrinkage, mold manufacturing and assembly errors, and mold wear. In addition, when designing the compression mold and injection mold, the matching of the process and structural parameters of the molding machine should also be considered. Computer-aided design technology has been widely used in plastic mold design. The structure of Blow Molding, casting mold and thermoforming mold is relatively simple. Compression molds, injection molds and mold conveying structures are more complex, and there are more parts that make up these molds. The basic parts are as follows: Forming parts, including punching die, stamping forming, and various forming cores, are the inner, outer or upper, lower, side, side hole, undercut and threaded parts of the formed product. Support fixed parts, including formwork plate, fixed plate, support plate, backing plate, etc., to fix the mold or support the pressure. Guide parts, including guide columns and guide sleeves, to determine the relative position of the mold or mechanism movement. Core pulling components including 4-shot needles, sliders, etc. are used to extract the movable core when the mold is opened to release the product. Push out parts, including push rod, push tube, push block, push plate, push ring, push rod fixing plate, push plate, etc., to demould the product. Injection molds widely use standard mold bases, which are composed of a group of basic parts with standardized and serialized structure, form and size. The mold base can be processed by itself according to the shape of the product. Using a standard mold base can help shorten mold cycle times.
