Punch forming device and punch forming process of square paper box component

Abstract

The invention relates to a punch forming device of a square paper box component. The punch forming device comprises an outer mold and an inner mold. The inner mold and the outer mold can relatively and vertically move, the inner mold is in a cuboid shape, and a cavity where the inner mold is downwards embedded is formed in the outer mold. The inner mold and the outer mold are both made of metal. The punch forming device is characterized in that the bottom of the cavity of the outer mold is hollowed; the cavity of the outer mold is divided into an upper section and a lower section; the portion, corresponding to the periphery of the upper section of the cavity of the outer mold, on a mold body is an upper section of the mold body of the outer mold, and the portion, corresponding to the periphery of the lower section of the cavity of the outer mold, on the mold body is a lower section of the mold body of the outer mold; the upper section of the mold body of the outer mold is provided with a heating component, and the lower section of the mold body of the outer mold is provided with a cooling flowing way; the depth of the upper section of the cavity of the outer mold is more than two times larger than the maximum embedding depth of the inner mold; the depth of the lower section of the cavity of the outer mold is also more than two times larger than the maximum embedding depth of the inner mold. The square paper box component manufactured by the punch forming device is square, clear and sharp in parison corner angle, each paper board top is smooth, upright and straight, and the production speed is high. The invention further provides a punch forming process of the square paper box component.

Description

[0001] technical field [0002] 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 [0003] 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...

Problems solved by technology

[0005] 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
