Metal die capable of being rapidly heated and cooled

Abstract

The invention relates to the field of industrial product molding, in particular to a metal mold for rapid heating and cooling. A metal mold for rapid heating and cooling, further comprising a local cooling box slidingly connected with the heating device, the local cooling box includes a box body, a positioning disk arranged on the box body, and a positioning disk installed on the positioning disk The cooling single piece, the positioning disk includes a plurality of positioning grids, the cooling single piece is installed on the positioning grid, the cooling single piece includes cooling pipes, cooling channels and devices arranged in the inner cavity of the positioning single block A plurality of cold air outlet holes on the lower surface of the positioning block and connected to the cooling channel. The purpose of the present invention is to provide a metal mold with rapid heating and cooling, which adopts a brand new design in heating, and also adds a local cooling device, which can effectively cool down the molding area of ​​the mold quickly and in a small range, with a high speed and no damage to the mold. Small.

Description

technical field [0001] The invention relates to the field of industrial product molding, in particular to a metal mold for rapid heating and cooling. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. 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 through the change of the physical state of the formed material. Under the action of external force, the blank becomes a tool with a specific shape and size. Widely used in blanking, 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 specif...

Problems solved by technology

This makes the heating of the mold require the advantages of intelligence, convenient control, and convenient adjustment. However, the heating devices in the prior art are often unable to flexibly adjust the heating temperature in terms of time and space.

[0005] In addition, heat transfer media are often used for heating molds, such as high-temperature liquid or high-temperature gas. When the flow rate of high-temperature liquid or high-temperature gas is too fast, on the one hand, the heat is discharged without sufficient interaction in time, and the heat transfer is not good. In place, serious loss and waste

On the other hand, too fast flow rate may cause the temperature to rise too fast in a short time, exceeding the specified temperature, causing inconvenience to heat control

[0006] 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.
