Injection mould for base of wine bottle packing box

Abstract

The invention relates to the field of an injection mould and discloses an injection mould for the base of a wine bottle packing box. The injection mould comprises a rack, and an upper mould is connected on the rack in a sliding mode. A lower mould is arranged on the rack and is positioned below the upper mould, a driving groove is fixedly formed in the rack, and the lower mould is connected in thedriving groove in the sliding mode. A piston cylinder is fixedly arranged on the rack and communicates with the driving groove, and a piston is connected in the piston cylinder in the sliding mode and is fixedly connected with the upper mould. A first wedge rod is fixedly arranged on the upper mould, a second wedge rod is connected on the rack in the sliding mode, and the first wedge rod butts against the second wedge rod. A vacuum pipe is fixedly arranged on the rack, and a sliding rod is fixedly arranged on the upper mould and is connected in the vacuum pipe in the sliding mode. Compared with the prior art, according to the scheme, after the upper mould moves, the lower mould is linked to move together, and therefore the efficiency of mould closing is improved; by the arrangement of thevacuum pipe, after mould closing is finished, the upper mould can continue to move for a distance to the direction close to the lower mould, so that the upper mould and the lower mould are more tighter, and therefore the purpose of saving raw materials is achieved.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to an injection mold for the base of a wine bottle packaging box. Background technique [0002] In the production and packaging of liquor, in order to look beautiful and promote sales, producers usually add a plastic packaging box outside the wine bottle. Since the base and bottle body of the one-time formed liquor plastic packaging box have an integrated structure, and the material and structure are the same, it is easy to As a result, the base of the plastic packaging box is not strong enough and the bottle body is too thick to waste raw materials. [0003] In order to solve the above problems, the invention patent with the Chinese patent application number 201620153947.0 discloses an injection mold for the base of a wine bottle packaging box, including a base, a fixed mold and a moving mold. The fixed mold is fixed on the base, and the moving mold is set on the upper end of the fix...

AI Technical Summary

Problems solved by technology

[0004] The above scheme solves the problem of the integrated structure of the base and bottle body of the liquor plastic packaging box existing in the prior art center by making the base separately with the fixed mold and the movable mold, but the above scheme still has the following problems: during injection molding, only the movable mold can Movement, on the one hand, the efficiency of mold clamping is low; on the other hand, the contact between the fixed mold and the movable mold is not close enough, which may cause the mold to be not tightly closed, and there will be a gap between the fixed mold and the movable mold, and there will be some The raw material enters the gap, so that the side wall of the injection molded product will have more molding waste, resulting in waste of raw materials
