[0002] Injection mold is a tool for producing plastic products; it is also a tool that gives plastic products a complete structure and precise size. Injection mold is also a processing method used in mass production of parts, mainly used in the industrial field. The injection mold process is to inject the heated and melted material into the mold cavity by high pressure, and after cooling and solidification, a molded product is obtained; according to the molding characteristics, it is divided into thermosetting plastic mold and thermoplastic plastic mold.

[0003] In the prior art, an injection molding mold is often required in the production and processing of lampshades. After the aluminum inner shell is placed on the lower mold, the lower mold is moved to the bottom of the upper mold in the injection molding machine through the base. After the upper mold moves downward through the top seat and is connected to the lower mold, the raw material is injected into the mold and wrapped around the outside of the aluminum inner shell for post-molding. However, in actual use, the existing injection molding mold is usually fixed to the mold base by bolts, etc., which makes it inconvenient to disassemble and replace the upper mold and the lower mold, so that the injection molding mold can only produce lampshade products of a single specification.
