Technical Field

[0001] The utility model relates to the technical field of automobile mold demoulding cooling, in particular to a rapid cooling mechanism for automobile mold demoulding. Background Art

[0002] The most important component of automobile molds is the cover mold, which is mainly a cold stamping mold. In a broad sense, "automotive molds" are the general term for molds for manufacturing all parts of automobiles, such as stamping molds, injection molds, forging molds, casting wax molds, glass molds, etc. In the prior art, when the automobile mold is demolded, the process requires that the mold needs to be cooled quickly. However, the existing automobile mold structure is complex and demolding is inconvenient. In addition, when in use, the demolding cooling efficiency is low, which makes it easy for the mold and the product to stick together, and causes product defects after demolding or even incomplete demolding.

[0007] Furthermore, corresponding cooling chambers are provided on the upper mold and the lower mold, and the cooling chambers are fixedly connected to the water inlet pipe and the drain pipe so that cooling water can enter the cooling chamber from the water inlet pipe in time, so that the cooling water can cool the automobile molds on the upper mold and the lower mold.
