Local cooling metal mold with stable side edge

Abstract

The invention relates to the field of industrial product molding, in particular to a locally cooled metal mold with stable sides. A side-stabilized local cooling metal mold, comprising a mold body and a heating device for heating the mold body, the heating device is equipped with a tool that can slide in the horizontal direction and is used to insert into the side of the mold body Side fixing device, the side fixing device includes an operating shaft for operation, a heat insulating block for heat insulation, and a protruding part at the end of the operating shaft for inserting into the mold body, the protruding The part includes an intrusion cone and an anti-locking piece arranged on the intrusion cone. The purpose of the present invention is to provide a metal mold with stable side and local cooling, which includes a side fixing device, which locks the mold from the side, increases the positioning stability of the mold in a high temperature environment, and also adds a local cooling device, which can effectively shape the mold The temperature of the area is quickly and slightly lowered, the speed is fast, and the damage to the mold is small.

Description

Technical field [0001] The invention relates to the field of industrial product molding, in particular to a local cooling metal mold with stable sides. Background technique [0002] Molds, various molds and tools used in industrial production to obtain desired products by injection molding, blow molding, extrusion, die-casting or forging molding, smelting, and stamping. A mold is a tool used to shape objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article by changing the physical state of the formed material. Under the action of external force, the blank becomes a tool with a specific shape and size. It is widely used in punching, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or inner cavity...

Problems solved by technology

[0007] There is still a problem when the mold is heated. The high-temperature heating medium such as high-temperature liquid or high-temperature gas will produce certain vibrations. These vibrations will cause bumps to the mold and affect the molding effect. Defective products, therefore, increasing the positioning stability of the mold under high temperature environment is also the research direction of mold design

[0008] In the actual production process, in addition to the need to heat the mold in advance, it is also necessary to cool the mold in the subsequent process. The existing cooling treatment often uses water cooling to cool the entire mold, but there are three cooling methods: Disadvantages: First, it needs to consume a lot of water resources, and the non-environmental protection also increases the production and operation costs of the enterprise; secondly, the mold needs to be heated up rapidly after cooling down, and a large-scale overall cooling of the entire mold often leads to excessive cooling. , so that the subsequent re-heating has an adverse effect; finally, for the overall cooling of the mold, the mold is frequently heated and cooled multiple times within a day, which is easy to cause damage and deformation to the mold body.
