Multi-process composite forming mold for food tank body

Abstract

The invention belongs to the technical field of food tank production dies, and particularly relates to a multi-process composite forming mold for a food tank body. The mold comprises a lower mold assembly and an upper mold assembly, wherein the lower mold assembly comprises a lower mold plate, a forming outer mold frame, a rib wire expansion core mold, a wedge block, an edge folding outer mold frame and an edge folding expansion core mold, a tank body cavity is formed between the rib wire expansion core mold and the forming outer mold frame, the outer side wall of the rib wire expansion coremold and the inner side wall of the forming outer mold frame are respectively provided with a rib line convex strip and a rib wire groove corresponding to the positions, the top of the rib expanding core die is provided with a core punching cavity, the upper die assembly comprises an upper die plate, an upper die and an upper punching core, inclined wedges which are vertically arranged are arranged on the periphery of the upper mold plate, the upper mold is arranged at the bottom of the upper mold plate and located above the rib wire expansion core mold, and the bottom of the upper template isalso provided with a rolling groove which is used for abutting against the upper opening part of the tank body so as to enable the upper opening part to be rolled into a circle. According to the multi-process composite forming mold of the food tank body disclosed, and a rib line, a folded edge and a rolled circle can be processed on the tank body of the food tank at a time.

Description

technical field [0001] The invention belongs to the technical field of molds for food can production, in particular to a multi-process compound molding mold for food can bodies. Background technique [0002] Such as figure 1 As shown, in the production and molding process of the can body of the existing metal food can, the mouth of the can body needs to be rounded, the can body near the mouth needs to be ribbed, and the bottom of the can needs to be folded. Among them, the mouth of the can body is made smooth by rolling, the can lid is closed and pressed on the can body by pressing the ribs, and the bottom of the can is used for the bottom sealing of the subsequent can body by the hemming of the bottom of the can. In the prior art, for the forming of the three parts of the can body of the food can, at least three processes are required for processing, and each process requires a set of forming molds, so more forming molds are required for production. The increase in the ...
