Description

Technical Field

[0001] The invention relates to the technical field of injection molds, and in particular to an injection mold with a high-efficiency temperature reduction function. Background Art

[0002] An injection mold is a tool specifically used to manufacture plastic products. The structure and size of the mold are designed according to the shape and size of the required product to ensure that the product can meet the expected quality and performance requirements. The cooling principle of the injection mold is mainly based on two methods: heat conduction and convection. During the injection molding process, the plastic material is injected into the mold cavity at a high temperature. As the material cools and solidifies, a large amount of heat is generated inside the mold. In order to ensure product quality and shorten the production cycle, this heat needs to be effectively removed from the mold; in the injection mold, the cooling system usually includes cooling waterways or cooling channels, which are in close contact with the wall of the mold. When the plastic material cools in the mold, the heat generated is transferred to the cooling waterway through the mold wall, and then carried away by water or other cooling media.

[0003] After searching, a Chinese patent with publication number CN210501271U discloses an injection mold with efficient cooling function, including a mold body and a base. An electric valve is also installed on the water outlet pipe, and a water storage plate is horizontally installed at the lower end of the water outlet pipe. A plurality of nozzles penetrating the water storage plate are installed at the lower end of the water storage plate. A square groove is provided on one side of the upper end of the base, and a water outlet groove penetrating the base is provided on one side of the inner lower end of the square groove. A connecting pipe is connected to the other end of the water outlet groove, and a slow-speed motor is fixed to one side of the upper end of the base. A straight plate is provided at the lower end of the mold body, and a transmission mechanism is provided between the straight plate and the output shaft of the slow-speed motor. A plurality of limit mechanisms are also provided between the lower end of the straight plate and the upper end of the base.

[0004] Based on the above search and the prior art, it is found that: currently, the cooling of injection molds mostly utilizes a water cooling system to achieve cooling of the injection molds and products; however, in order to meet the injection molding efficiency, the cooling process is generally terminated after the temperature drops to a certain temperature; at this time, the injection molds and products still have a certain temperature, which is generally 60°C-80°C. In this case, there is a certain risk of scalding when the operator operates, and during the transportation process, the product has a certain risk of damage due to not being completely cooled and formed.
