[0002] With the rapid development of the plastics industry and the continuous improvement of the strength of general and engineering plastics, the application scope of plastic products is also expanding, and the amount of plastic products is also increasing. Injection molds, also known as plastic molds, are tools for producing plastic products. They are composed of several groups of parts, and there is a molding cavity in this combination. During injection molding, the mold is clamped on the injection molding machine, and the molten plastic is injected into the molding cavity, where it is cooled and shaped. Then the upper and lower molds are separated, and the product is ejected from the mold cavity by the ejection system. Finally, the mold is closed for the next injection molding. The entire injection molding process is carried out in a cycle.

[0003] After searching, in the prior art, Chinese patent publication number: CN218803673U discloses an injection mold that is easy to dissipate heat. The utility model includes a workbench, a mold shell 1 is fixedly installed in the middle of the top of the workbench, and the top of the mold shell 1 is movably connected to the mold shell 2, and the middle of the top of the left and right sides of the mold shell 2 are both provided with slots. The utility model is provided with a fan, a metal sleeve, a heat-conducting block, a metal block and a metal plate. When the fan is running, gas will be extracted through the air inlet pipe, and then discharged into the inside of the mold shell 2 through the exhaust pipe, so that the metal plate can be cooled. The heat absorbed by the metal sleeve will be transferred to the metal block through the heat-conducting block. As the water flows through the inside of the slot, the metal block can be cooled. The metal sleeve and the metal plate can have a good cooling effect on the injection molded object inside the mold shell 1, and when one of the heat dissipation is not working, the other can also have a cooling effect.

Mold shell two is fixedly installed with cooling components such as a fan. Replacing the mold as a whole will increase the cost of use. In addition, mold shell one and mold shell two of the device are not easy to disassemble, which increases the difficulty of replacement and maintenance work for operators. The device does not solve this problem. Utility Model Content
