[0002] After the injection molded parts are formed in the mold, they need to be cooled and shaped before they can be removed from the mold. The cooling time generally accounts for 80% of the molding cycle. Since the time used for each mold to form a plastic part during injection molding is short, the heat lost through radiation and conduction of the mold is less than 10%. Therefore, more than 90% of the heat of the plastic melt must be taken away by cooling water. Therefore, to improve the production efficiency of molding, sufficient cooling measures must be taken. If the hot water is cooled directly by purchasing a cooling tower, although the cooling effect is good, the cost is too high. Therefore, in order to reduce the cost of hot water cooling, improve the cooling efficiency of hot water, and meet the hot water cooling requirements of small and medium-sized enterprises, it is necessary to design a mold hot water cooling circulation device.
