Straightly-jacking and obliquely-drawing device for injection mould

Abstract

The invention discloses a straightly-jacking and obliquely-drawing device for an injection mould. The device comprises an obliquely-drawing core block (1), an obliquely pulling block (2), a straightly-jacking core block (3), a limiting rod (4) and a spring (5). The obliquely-drawing core block is provided with a buckle head A and a buckle groove A; the obliquely pulling block is provided with a buckle head B and a buckle groove B; an oblique slideway is formed in a straightly-jacking mould core of the straightly-jacking core block; the obliquely-drawing core block slides into the oblique slideway , and the obliquely pulling block is positioned right below the obliquely-drawing core block and is connected with the buckle groove B by the buckle head A in a sliding and buckling manner and with the buckle groove A by the buckle head B in a sliding and buckling manner; the obliquely-drawing core block, the obliquely pulling block and the straightly-jacking core block are positioned in a mounting groove hole of a movable mould core, the obliquely pulling block and the movable mould core are fixedly connected, and the straightly-jacking core block and the movable mould core are connected in a sliding manner; when the core is drawn, the straightly-jacking core block directly jacks upwards a product to demould, and at the same time, under the action of the buckle head A, the buckle groove A, the buckle head B and the buckle groove B, the obliquely-drawing core block is rightwards, downwards and obliquely drawn from the product, and the obliquely-drawing core block is released from the obliquely pulling block; after the obliquely-drawing core block stops, the straightly-jacking core block continuously jacks and pushes the product to be released from the movable mould core; through the adoption of the technical schemes of straightly-jacking and obliquely-drawing, the injection mould required to be obliquely drawn achieves the purposes of body shrinkage and cost reduction.

Description

technical field [0001] The invention relates to an oblique drawing and demoulding device for an injection mold, in particular to an injection mold straight-top oblique device for demoulding an oblique core-pulling block embedded in a product oblique hole, oblique rib or undercut structure. pumping device. Background technique [0002] The injection mold is provided with an oblique core-pulling block at the oblique hole, oblique rib or undercut structure of the molded injection molded product. The core-pulling of the oblique core-pulling block is demoulded. Top core-pulling or cable-pull core-pulling demoulding, whether it is a slanted top or a slanted pull device, needs to occupy a large internal space of the mold, resulting in an increase in the shape of the mold and an increase in cost. Large, high-cost problems and deficiencies. Contents of the invention [0003] Aiming at the problems and deficiencies in the above-mentioned prior art, the present invention adopts a d...

[0002] The injection mold is provided with an oblique core-pulling block at the oblique hole, oblique rib or undercut structure of the molded injection molded product. The core-pulling of the oblique core-pulling block is demoulded. Top core-pulling or cable-pull core-pulling demoulding, whether it is a slanted top or a slanted pull device, needs to occupy a large internal space of the mold, resulting in an increase in the shape of the mold and an increase in cost.
