High-efficiency injection mold production cooling device

Abstract

The invention discloses a high-efficiency injection mold production cooling device in the technical field of injection mold production. The device comprises a base, an injection molding lower mold andan injection molding upper mold, top plates are arranged at the tops of supporting plates located on the left side and the right side, two sets of cooling cavities are located on the outer sides of the injection molding lower mold and the injection molding upper mold, a plurality of sets of heat conducting columns are uniformly arranged on the inner walls of one opposite sides of the cooling cavities on the left side and the right side, and cooling circulation pipes are wound on the outer walls of the plurality of sets of heat conduction columns on the left side and the right side. When the cooling cavities on the left side and the right side are attached to each other, the heat conduction rubber is in contact with the injection molding lower mold and the injection molding upper mold, cooling water in a cooling water tank is injected into telescopic water injection hoses on the left side and the right side through a water pump during cooling, heat generated by an injection mold is exported outward through the heat conduction rubber, a water cooling block and the heat conduction columns, so that heat cannot be gathered, the circulating flow of cooling water in the cooling circulation pipe and the water cooling block is matched, so that the high-efficiency water cooling is achieved, moreover, the cooling uniformity is high, and damage to the injection mold is avoided.

Description

technical field [0001] The invention relates to the technical field of injection mold production, in particular to a high-efficiency injection mold production cooling device. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is to add a hot-melt plastic material into a closed mold cavity with a desired shape in the lower injection mold, and mold the upper and lower molds of the injection mold to synthesize the desired product shape and structure, and wait until the plastic material cools. After curing, open the injection mold to eject the plastic part to obtain the desired product. [0003] Since the injection mold has been kept at a high temperature during the production process, most of the existing ones are cooled automatically. This method is not only time-consuming, but also poses a certain safety threat to the staff. At pr...

[0003] Since the injection mold keeps a high temperature during the production process, most of the existing ones make it automatically cool down. This method not only takes a long time, but also poses a certain safety threat to the staff. Currently, it is used to assist the cooling device of the injection mold There is a common problem of slow cooling, which affects work efficiency. Therefore, we propose a high-efficiency cooling device for injection mold production
