Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a cooling mechanism for a plastic injection mold. Background Art

[0002] Moulds are various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. Moulds are tools used to make molded objects. This tool is composed of various parts. Different moulds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material.

[0003] After searching, the application with patent number CN214324002U discloses a cooling mechanism for a plastic injection mold, including a lower mold and a cooling device. The surface of the lower mold is provided with a cooling device, and the cooling device includes two second placement plates. The top ends of the two second placement plates are slidably connected to the lower mold, and the two side walls of the second placement plates are slidably connected to the first placement plates. By placing the lower mold into the water tank, the lower mold can be quickly cooled, which facilitates the movement of the mold.

[0004] However, due to the setting of the clamp block and the net, the lower mold falls onto the net by sliding the clamp block, thereby ensuring that the lower mold is in contact with water for cooling. The cooling speed is slow, and the water in the water tank will steadily increase with the cooling of the mold, thereby affecting the next cooling efficiency. At the same time, due to the setting of the lower mold and the upper mold, the bottom surface of the lower mold is in contact with water, and only the bottom surface of the finished product in the injection cavity can be cooled, and the cooling effect is poor.

[0005] Therefore, we propose a cooling mechanism for a plastic injection mold. Utility Model Content
