Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to an injection molding circulating cooling device. Background Technology

[0002] Injection molding is a molding process that uses plastic molds to process thermoplastic or thermosetting plastic materials into products with specific shapes and sizes. Specifically, the plastic raw material is first added to the barrel of an injection molding machine. Through heating and screw rotation, it is plasticized into a uniform melt. Then, driven by the plunger or screw of the injection molding machine, the melt is injected into a closed mold cavity at high pressure and high speed. After holding the pressure, cooling, and solidification, the mold is opened, and the molded product is removed from the mold using an ejector device.

[0003] Circulating cooling water may contain impurities and microorganisms. After prolonged use, impurities will settle in the pipes, and microorganisms will grow and form mucus, causing pipe blockage, reducing the efficiency of cooling water transport, and also affecting heat exchange and cooling performance. Therefore, it is necessary to propose an injection-molded circulating cooling device. Utility Model Content
