Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to an injection molding mold with a preheating structure for processing. Background Art

[0002] Injection molding is a processing method used in the mass production of certain parts with complex shapes. Specifically, it refers to the high-pressure injection of heated and molten plastic into the mold cavity by an injection molding machine. After cooling and solidification, a molded product is obtained. The product usually uses rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. Injection molds are a tool for producing plastic products. Many workpieces with complex internal structures that are difficult to process can be prepared through injection molds. However, many injection molded workpieces are often easily damaged during vertical demolding, so an injection mold that is easy to demold is needed.

[0003] Based on the above, the existing injection molds used for processing and molding have simple structures, low production efficiency, poor injection molding effect, high demoulding damage rate and other disadvantages. When in use, the existing injection molds need to be manually disassembled for each injection, which is very troublesome to operate, resulting in slow production speed. When high-temperature raw materials are injected into the injection mold, there is a possibility of shrinkage and deformation of the injection mold, and bubbles will appear inside, resulting in poor product quality. It is not easy to take out during demoulding, causing product damage. For this reason, the utility model improves the injection mold with a preheating structure and can be used quickly without manual disassembly and installation. Utility Model Content
