Structural parts Plastic mold factory:
The structure of blow molds, casting molds and thermoforming molds is relatively simple.
Compression molds, injection molds, and transfer molds are more complicated in structure, and there are more parts that make up this type of mold.
The basic parts are:
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.
④ 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 by itself according to the shape of the product. The use of standard mold bases is beneficial to shorten the molding cycle.
2. The role of common mold base parts
Fixed mold base plate (panel): Fix the front mold on the injection molding machine.
Runner plate (nozzle plate): Remove the waste handle when opening the mold to make it fall off automatically (three-plate mold).
Fixed mold plate (A plate): the front mold part of the molded product.
Movable mold fixing plate (B board): the back mold part of the molded product.
Cushion: Mould foot, its function is to make the top plate have enough space for movement.
Pushing plate: When opening the mold, the product is pushed out of the mold by pushing out parts such as ejector pins, top blocks, and inclined tops.
Movable mold base plate (bottom plate): Fix the back mold on the injection molding machine.
Guide post and guide sleeve: play the role of guiding and positioning, assisting the opening of the front and rear molds, and the basic positioning of the mold.
Support column (support head): Improve the strength of the B board, effectively avoiding the deformation of the B board due to long-term production.
Top plate guide column (Zhong Tuo Division): guide and position the push plate to ensure smooth ejection.
