Integral molded packaging box, molding die and molding method for molding the packaging box

Abstract

The invention discloses an integrally formed packing box and a forming mould and method for forming the packing box. The packing box comprises a bottom plate, a left side plate, a left cover plate, a front side plate, a front cover plate, a right side plate, a right cover plate, a rear side plate and a top cover; the packing box is formed by a piece of paper though bending and fastening; the paper comprises a first folding sheet, a second folding sheet, a fourth folding sheet, a fourth folding sheet and a fifth folding sheet, which are integrally connected; an insertion tongue is arranged at the free end of the fourth folding sheet and a socket which is matched with the insertion tongue is arranged on the second folding sheet; the first folding sheet is bent to form the left side plate and the left cover plate; the second folding sheet is bent to form the front side plate and the front cover plate; the third folding sheet is bent to form the right side plate and the right cover plate; the fourth folding sheet is bent to form the rear side plate and the top cover; the left side plate, the front side plate, the right side plate and the rear side plate are connected to form the bottom plate; and the fifth folding sheet is bent to be clamped between the bottom plate and the top cover. The whole packing box is simple in structure, convenient to process, safe, environment-friendly and low in cost.

Description

technical field [0001] The invention relates to the field of packaging, in particular to an integrally formed packaging box, a forming mold for forming the packaging box and a forming method thereof. Background technique [0002] Packaging is inseparable from the process of goods from the factory to the final consumer. The packaging box bears the important responsibility of containing, protecting the product and being beautiful. Among them, paper packaging boxes are more and more widely used in product packaging because of their light weight, foldability, easy transportation, recyclability, and environmental protection. At present, the existing paper packaging boxes are generally first crimped on the paper sheet to form creases on the paper sheet, and then form the required packaging box along the creases, and in the process of forming the packaging box, The connecting surface or sealing part of the packaging box is generally connected or sealed by nailing, gluing or stick...

AI Technical Summary

Problems solved by technology

At present, the existing paper packaging boxes are generally first crimped on the paper sheet to form creases on the paper sheet, and then form the required packaging box along the creases, and in the process of forming the packaging box, The connecting surface or sealing part of the packaging box is generally connected or sealed by nailing, gluing or sticking tape. The forming process of the entire packaging box is cumbersome and not environmentally friendly, resulting in waste of resources and high processing costs.

Further, the existing packaging box sometimes cannot protect the products contained in the packaging box due to insufficient support, and adding auxiliary structures such as supporting linings further increases the processing steps and manufacturing costs.
