Core-pulling and demolding sequential structure for lateral sliding block insert

Abstract

The invention provides a core-pulling and demolding sequential structure for a lateral sliding block insert. The structure enables one-step molding of a product having an irregular torus with a hole groove structure, improves the product processing precision, and enhances the product production efficiency. The structure comprises a front mold insert, a rear mold insert, a board A, a board B, and two side sliding blocks. The front mold insert and the rear mold insert combine to form a cavity inner surface. The two side sliding blocks piece together to form a cavity outer surface. The inside of the cavity is the product, the outer torus of which is provided with a hole groove structure. A stripper plate supports the board A, and the two side sliding blocks support the board B. The structure is characterized in that: the outer side faces of the side sliding blocks are inclined planes flaring outward from top to bottom, the inclined planes of the side sliding blocks are clamped on the inner inclined planes of corresponding inclined pulling blocks through a T-shaped guide rail structure, the outer inclined planes of the inclined pulling blocks clings to the inner inclined plane of the board A, the upper ends of the two inclined pulling blocks are respectively located in the central installation cavity of the board A, and the lower part of the stripper plate is in fastening connection with the upper end of drawing blocks, the inner hooks of which are embedded in corresponding grooves of the inclined pulling blocks.

Description

technical field [0001] The invention relates to the structural technical field of product molds, in particular to a core-pulling and then demoulding structure of a side slider insert. Background technique [0002] The existing irregular torus products generally form the annular surface cavity by combining two slider inserts, and then demould through the inclined guide column structure, but for the irregular torus with holes In the prior art, holes and grooves are generally formed on the surface through secondary processing. Since the secondary processing requires secondary positioning, the processing accuracy of the product is low, and the secondary processing makes the production efficiency of the product low. Contents of the invention [0003] The invention provides a core-pulling and then demoulding structure of a side slider insert, which enables the product with a hole-groove structure on the irregular circular ...
