Forced demoulding mechanism

Abstract

The invention provides a forced demoulding mechanism which comprises an ejecting plate, an inclined bolt mechanism, a forced demoulding insert fixing plate, a forced demoulding insert, a returning column and a thimble, wherein the ejecting plate is arranged between a male mould bearing plate and a lower fixing plate in the mould; the inclined bolt mechanism is arranged on the ejecting plate; the forced demoulding insert fixing plate is arranged in the male mould plate; the forced demoulding insert is arranged on the forced insert fixing plate; according to the requirements of product shapes, forced demoulding inserts with different shapes are replaced on the forced demoulding insert fixing plate, and the quantity of the forced demoulding inserts is increased or decreased; the returning column is fixed between the ejecting plate and the forced demoulding insert fixing plate; and the thimble is arranged on the ejecting plate. When the products are forcibly demoulded by the forced demoulding mechanism, the inclined bolt mechanism has no damage to the products.

Description

【Technical field】 [0001] The invention relates to a forced demoulding mechanism, in particular to a forced demoulding mechanism with oblique pins. 【Background technique】 [0002] The existing forced demoulding mechanism, especially when the formed product requires a slanted pin mechanism, often causes the slanted pin and the product to move in the opposite direction due to the multiple openings of the mold during forced demoulding, causing the slanted pin to strain the product, for example :Such as figure 1 As shown in the schematic diagram of the clamping structure of the forced demoulding mechanism in the prior art, an ejector plate 10 is arranged between the male mold carrier plate 1 and the lower fixing plate 3, and the ejector plate 10 can be placed on the male mold Carrying plate 1 and said lower fixed plate 3 do radial reciprocating movement, and an oblique pin mechanism 101 is arranged on said ejector plate 10, and said oblique pin mechanism 101 follows said ejector...

AI Technical Summary

Problems solved by technology

[0003] like figure 2 As shown in the schematic diagram of the mold opening structure of the forced demoulding mechanism in the prior art, the male mold carrier plate 1 is separated from the male template 2 by a certain distance, and the insert 102 moves in the same direction and at the same distance with the male mold carrier plate 1, so The part of the product corresponding to the inlet 102 obtains a certain elastic space, so that the product is easier to break away from the mold, and the ejector plate 10 moves in the opposite direction and at the same distance relative to the male mold carrier plate 1. Because the male template 2 remains stationary, therefore, when the mold is opened, due to the movement of the male mold support plate 1 relative to the male template 2 and the ejector plate 10 remaining stationary and ejected relative to the male template 2 The movement of the plate 10 relative to the male mold support plate 1 causes the oblique pin mechanism 10 to generate a certain pulling force relative to the part corresponding to the oblique pin mechanism 10 on the product, and this tension often damages the part corresponding to the oblique pin mechanism 10 on the product. part, and the entry 102 is fixed on the male mold support plate 1, so the entry 102 is relatively long, and it is easy to be broken during demoulding, which causes great trouble during production
