Technical Field

[0001] The utility model relates to the technical field of mold cooling, in particular to a molding mold provided with a circulating cooling cavity. Background Art

[0002] Injection molds are tools for producing plastic products, and they are also tools that give plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to the process of injecting heated and melted plastic into the mold cavity under high pressure by an injection molding machine, and then cooling and solidifying to obtain a molded product. However, the existing molding molds have poor cooling performance during use, which makes the molding efficiency of the mold low and the quality of the molded product poor. Therefore, a molding mold with a circulating cooling cavity is urgently needed to solve the above problems. Utility Model Content

[0005] Preferably, the circulating cooling device includes a discharge hose, a delivery hose, a cooling fixed ring and a spiral cooling ring, the spiral cooling ring is fixedly installed inside the cooling fixed ring, and the delivery hose and the discharge hose are fixedly connected at both ends of the spiral cooling ring.

[0006] Preferably, the discharge hose and the delivery hose are located outside both ends of the cooling fixed ring.

[0007] Preferably, the two cooling fixing rings are respectively arranged to fit the exterior of the upper mold and the lower mold.

[0008] Preferably, the spiral cooling ring is arranged in a spiral shape, and the spiral cooling ring is evenly distributed inside the cooling fixed ring.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] The utility model can fix the lower mold by a fixed mounting plate, and can connect the upper mold with an external driving device by a fixed connecting threaded pipe, so that the upper mold can be raised and lowered, and the material body can be transported between the upper mold and the lower mold through the injection pipe. During the injection molding process, the coolant is transported to the two spiral cooling rings through the conveying hoses in the two circulating cooling devices, so that the coolant can be transported in the spiral cooling ring and discharged from the discharge hose to form a circulating cooling body, so that the coolant transported in the spiral cooling ring can fully cool the cooling fixing ring. Since the material of the cooling fixing ring is a material that can quickly conduct heat, the interior of the upper mold and the lower mold can be quickly, fully and continuously cooled through heat exchange, so that the injection molded products in the upper mold and the lower mold have good quality.
