Description

Metal mold with cooling function

Technical Field

The utility model relates to a mould manufacturing technical field specifically is a metal mold with cooling function.

Background

The mould is various moulds and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to shape an article, the tool being made up of various parts, and different molds being made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material.

In the die-casting production process, the high-temperature metal solution is pressed into a die cavity, the die cavity is cooled and formed through heat exchange with the die, and the die-casting die absorbs heat brought by the high-temperature metal solution and dissipates heat through the space and a die-casting machine. In general, the amount of heat absorbed is larger than the natural amount of heat dissipated, and thus, as the die casting process proceeds, the die temperature gradually increases. If the temperature of the mold is too high, the quality of the casting and the service life of the mold are affected. In order to perform normal die casting production, it is necessary to maintain the die temperature substantially constant, and therefore we propose a metal die having a cooling function.
