Composition of the plastic mold and mold base components common action
Blow molding, cast molding and thermoforming mold structure is relatively simple.
Compression molding, injection molding and transfer molding structure is more complex, parts constituting such mold is greater.
The basic components are:
① molded parts, including die, punch, various molding core, are forming within the article, the outer surface or the upper and lower end faces, side hole, undercut and threaded parts.
② support fixing parts, including mold base plate, fixing plate, bearing plate, pads, etc., to support the fixed mold or pressure.
③ guide parts, including guide post and guide to determine the relative positions of the mold or launch mechanism movement.
④ Pulling parts, including oblique pins, sliders, etc., for extracting the active core when the mold is opened, releasing the article.
⑤ Release parts, including putting, push tube, push blocks, push pieces of board, pushing member ring, putting the fixed plate, push plate, etc., to make the product release. Promote the use of injection molding multi-standard mold, this mold is already standardized by the structure, form and dimensions and basic part series sets a combination of its own cavity can be processed in accordance with article shape. Use of standard mold will help shorten the molding cycle.
2, the role of common mold base parts
Fixed mold base plate (panel): the front mold fixed on the injection molding machine.
Manifold (nozzle plate): When mold removal waste handle it automatically off (three plate mold).
Fixed mold fixing plate (A plate): molding products before the mold portion.
Movable mold fixing plate (B board): the molded product after mold portion.
Pad: mold foot, its role is to make the roof there is enough space.
Push Plate: Release of parts when the mold by ejector, the top block, lifter and other products out of the mold.
The movable mold base plate (bottom): fixing the mold after the injection molding machine.
Guide post and guide sleeve: the role played oriented positioning, the auxiliary mold around the mold, and the mold with the basic position.
Support column (hold head): Increase the intensity B board, effectively prevent long-term production led to B plate deformation.
Roof pillar (in torr Division):-oriented positioning of the push plate to ensure smooth ejection.
