Metal mold with top heating function

Abstract

The invention relates to the field of molding of industrial products, in particular to a metal mold with top heating. The present invention is achieved through the following technical solutions: a metal mold that includes a top temperature rise, including a mold body and a heating device for heating the mold body, the hinge plate is provided with a top plate temperature regulating member, the The top plate thermostat includes an operating rod, a heating contact block connected to the end of the operating rod, a lower pressure block fixedly sleeved on the operating rod, a heat insulating member located above the An elastic ring between the heating element and the lower pressing block, the heating contact block is located on the lower surface of the hinge plate one. The purpose of the present invention is to provide a metal mold with top heating, which adopts a new design in heating, which can not only realize the heating effect of constant temperature of the package, but also realize the heating of the local position, which is convenient to adjust and set the top position of the mold. There is a special regulation structure.

Description

technical field [0001] The invention relates to the field of molding of industrial products, in particular to a metal mold with top heating. 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 specific contou...

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
