Description

Technical Field

[0001] The utility model belongs to the technical field of mold accessories, and in particular relates to a mold water cooling device. Background Art

[0002] The mold mainly realizes the processing of the shape of the object by changing the physical state of the molded material. The mold is mainly used to manufacture the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, the mold is a tool used to make molded objects, which is composed of various parts, and different molds are composed of different parts.

[0003] During the use of the mold, high temperature will be generated. When the mold works at high temperature, it may be deformed due to thermal stress, resulting in defects in the produced product. Therefore, cooling the mold is particularly necessary. By cooling the mold, the mold surface can be quickly cooled, thereby shortening the equilibrium time of the mold and improving the production efficiency of the mold processing. In addition, the temperature of the mold can be reduced, thermal stress can be reduced, thereby reducing the defect rate of the product and improving product quality. Water cooling is one of the main means of cooling the mold. However, the water cooling device currently used for the mold generally adopts the method of circulating the cooling medium to cool the mold. Although it can achieve efficient cooling of the mold, the cooling medium has a certain temperature after cooling the mold. If it is directly refrigerated again for cooling the mold, on the one hand, it will cause the loss of waste heat, and on the other hand, it will consume more energy for cooling, thereby increasing energy consumption and cooling costs. For this reason, the present application proposes a mold water cooling device. Utility Model Content
