Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold with a cooling function. Background Art

[0002] A car rearview mirror is a device used by car drivers to observe the rear of the car. It is usually installed on the door of the car or hung on the internal rearview mirror. Car rearview mirrors can be classified into two categories: external rearview mirrors and internal rearview mirrors. The main material of car rearview mirrors is plastic. When making such materials, injection molds need to be made in advance. Injection molds, also known as injection molding molds, are one of the molds used to produce plastic products. The production process of injection molds requires the use of advanced CNC processing technology to ensure the accuracy and quality of the molds. Injection molds are indispensable tools in the injection molding process. Their main function is to inject molten plastic into the mold for cooling and molding. The design and manufacture of injection molds can be customized according to the shape, size, material and other requirements of the product to ensure the production of qualified products.

[0003] For example, the Chinese patent with application number 202022807740.X, authorization publication number CN213733145U, and invention name "A kind of injection mold for automobile rearview mirror cover" discloses an injection mold for automobile rearview mirror cover, which belongs to the field of automobile parts processing technology, and includes a lower module, an upper module and an injection molding device. The upper module is located between the lower module and the injection molding device, and the lower module has a first molding groove on the end face of the side close to the upper module, and the upper module has a second molding groove on the end face of the side close to the lower module. The upper module has an injection molding hole on the end face of the side away from the lower module, and the injection molding device includes a connecting part and an electric heating pipe, and the connecting part is installed on the end face of the upper module away from the lower module, and the connecting part has a connecting channel, and the electric heating pipe is arranged inside the connecting part and around the connecting channel.

[0004] The injection mold can locally heat the connection channel connected to the injection hole to prevent the residual molten plastic from solidifying due to the cooling of the inner wall of the injection hole, thereby reducing the frequency of cleaning and maintenance of the injection mold. However, it is known that during the injection molding process, in order to improve the quality of the workpiece, it is usually necessary to wait for the workpiece to cool down before taking the workpiece out of the mold to reduce damage to the workpiece. However, the injection mold in the prior art has a poor cooling effect on the workpiece, resulting in a long cooling time, which ultimately affects the overall work efficiency. Utility Model Content
