Plastic Injection Mold is a kind of mold and is a good helper for mass production of plastic products. There are many types of plastic molds, such as blow molds, casting molds, and thermoforming molds with simple structures. Compression molds, injection molds, and transfer molds are more complicated in structure, and there are more parts that make up such molds.
Here we introduce what are the basic parts of general plastic molds, we summarize them into the following five types:
①Molding parts, including concave molds, convex molds, and various molding cores, are parts of the inner and outer surfaces or upper and lower end faces, side holes, undercuts and threads of the molded product.
②Support fixed parts, including mold base plate, fixed plate, support plate, cushion block, etc., to fix the mold or support pressure.
③Guiding parts, including guide posts and guide sleeves, are used to determine the relative position of the movement of the mold or ejection mechanism.
④The core-pulling parts, including diagonal pins, sliders, etc., are used to pull out the movable core when the mold is opened to demold the product.
⑤Push out parts, including push rod, push tube, push block, push plate, push ring, push rod fixing plate, push plate, etc., to demold the product. Standard mold bases are commonly used for injection molds. This mold base is a complete set of basic parts that have been standardized and serialized in structure, form and size. The mold cavity can be processed according to the shape of the product. The use of standard mold bases is beneficial to shorten the molding cycle.
