Automobile die

Abstract

The invention discloses an automobile die. The automobile die comprises an upper die body and a lower die body, wherein a closed forming cavity is formed between the upper die body and the lower die body when the upper die body and the lower die body are clamped, an injection molding channel and an air channel are formed in the upper die body, the injection molding channel communicates with the forming cavity, a heat conduction channel is formed in the upper die body and wraps the forming cavity, the air channel communicates with the heat conduction channel, symmetrical openings are formed inthe inner wall of the air channel, symmetrical adjusting sliding grooves are formed in the two sides of the outer wall of the air channel, symmetrical through openings are formed in the two sides of the side wall of each adjusting sliding groove, the bottoms of the adjusting sliding grooves abut against the heat conduction channel, air bags are arranged in the adjusting sliding grooves, sliding blocks are arranged on the air bags, inclined openings are formed in the middles of the two sliding blocks, and two high-pressure cavities and air pipes connected with the output ends of the high-pressure cavities respectively are arranged on the upper die body. According to the scheme, the cooling time is short, the efficiency is high, water can be saved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of auto parts equipment, and in particular relates to an auto mould. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products are usually injection molded with rubber or plastic. Injection molding can also be divided into injection molding molding method and die casting method. [0003] The vast majority of auto parts are molded by injection molding. Generally, injection molding machines, namely injection machines and injection molding machines, are used. Injection molding machines make thermoplastic or thermosetting plastics into various shapes of plastic auto parts using plastic molding molds. , so the injection molding of auto parts is achieved through injection molding machines and injection molds. [0004] The existing injection mold includes a die and a lower die. The die is a die and the die is a punch. When the die and the die are engaged, a...

Problems solved by technology

This heat dissipation method is to dissipate heat from the outside, and the heat transfer speed of the plastic melt is slow, which will reduce the efficiency of plastic melt molding, and at the same time waste a lot of water, resulting in increased manufacturing costs
