Stamping equipment and stamping process for square carton components

Abstract

A stamping forming equipment for a square carton member, comprising an outer mold and an inner mold, the inner mold and the outer mold can move vertically relative to each other, the inner mold is in the shape of a cuboid, and the outer mold is formed with a cavity for the inner mold to embed downward; Both the inner mold and the outer mold are made of metal; it is characterized in that the bottom of the outer mold cavity is hollowed out; the outer mold cavity is divided into upper and lower sections; the corresponding mold body around the upper section of the outer mold cavity is an outer The upper part of the mold body, the corresponding mold body around the lower part of the outer mold cavity is the lower part of the outer mold body; the upper part of the outer mold body is provided with a heating member, and the lower part of the outer mold body is provided with a cooling channel; the depth of the upper part of the outer mold cavity It is more than twice the maximum embedding depth of the inner mold; the depth of the lower part of the cavity of the outer mold is also more than twice the maximum embedding depth of the inner mold. The square carton component parison produced by the invention has square, clear and sharp edges and corners, each cardboard surface is flat and straight, and the production speed is fast. The invention also provides a stamping forming process of the square carton component.

Description

technical field [0001] The invention belongs to the technical field of producing packaging cartons, and in particular relates to a stamping forming equipment and a stamping forming process of a square carton component. Background technique [0002] Square cartons are generally provided with a square box body and a square cover. Wherein, the square box body includes a box bottom and four side walls, and the box bottom is vertically connected with the four side walls; the square cover body includes a cover surface and four cover edges, and the cover surface and the four cover edges are also vertically connected. Therefore, from a structural point of view, there are similarities between the square box body and the square lid body, wherein the bottom of the box is similar to the lid surface, and the four sides of the lid are similar to the four sides of the side walls. Because there are similarities in the structures of the two, in this application document, the square box or t...

Problems solved by technology

[0004] The disadvantages of the existing above-mentioned stamping and forming equipment are: 1. After the cardboard is bent, the edges and corners of the square carton member are not square enough, not clear enough, and not sharp enough, and the cardboards on each side of the carton member parison are not straight enough; 2. The process of taking out the carton component from the outer mold is cumbersome, and the force of the taking-out action cannot evenly act on the periphery of the carton component, but can only act on one or two local points, which will affect the shape of the newly formed square. The squareness of the carton component parison; 3. The production speed is slow
