Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically a combined water-cooled mold. Background Technology

[0002] Injection molds are tools used to produce plastic products. They give plastic products precise dimensions and complete structures. The design and manufacture of injection molds have a direct impact on the quality of the final product and production efficiency.

[0003] During the use of injection molds, friction, extrusion, and other factors can cause the mold to overheat. Cooling the plastic is necessary during injection to ensure proper molding. Existing technology (Chinese patent application CN202421161970.5, filed on 2024-05-27) describes a water-cooling structure for injection molds. During use, it includes a lower mold: a circulating chiller interface is fixedly provided on one side of the lower mold; an injection cavity is opened inside the lower mold; a water flow dispersion device is provided inside the lower mold to disperse the water flow; the water flow dispersion device includes a water inlet pipe, one end of which is fixedly connected to one end of the circulating chiller interface, and the other end of which is fixedly provided with a distributor; a hot water extraction device is provided on one side of the lower mold; an upper mold is movably mounted above the lower mold, and two hydraulic cylinder output columns are fixedly mounted on the upper end of the upper mold. An injection pipe penetrates the inner side of the upper mold. The water flow dispersion device helps to disperse the flow direction of the cooling water, enabling uniform cooling of the lower mold; the hot water extraction device facilitates the extraction and circulation of hot water.

[0004] Although existing technology can effectively cool the lower mold, the cooling effect on the upper mold is insufficient during operation, and the cooling of the upper mold, lower mold and cavity is uneven.
