[0002] As people's requirements for automobile performance continue to increase, the requirements for automobile appearance and interior decoration are also getting higher and higher. Automobile lampshades are mainly plastic parts, so the quality of injection molds is an important factor affecting automobile lampshades.

[0003] When applying for the present invention, the applicant found through search that a Chinese patent disclosed a "A kind of automobile lamp cover injection mold", and its application number is "202223577830.X". The patent mainly includes a mounting plate, the upper surface of which is fixedly mounted with a lower mold, the side surface of the upper end of the lower mold is threadedly connected with a limiting ring, the upper surface of the lower mold is provided with a plug-in groove, the inner wall of the plug-in groove is slidably connected with a sliding column, the inner bottom wall of the plug-in groove is provided with a sliding groove, the inner wall of the sliding groove is slidably connected with a sliding plate, the lower end of the sliding column is fixedly connected to the upper surface of the sliding plate, and the upper surface of the sliding plate is fixedly mounted with an upper top column. In the automobile lampshade injection mold, when the upper mold is moved upward after stamping, the limit ring can remove the lampshade mold adhering to the surface of the upper mold from the surface of the upper mold and retain it on the inner wall of the lower mold. After the limit ring rotates and moves upward, the sliding column releases the downward pressure effect of the limit ring, and the compression spring can push the sliding plate upward, and the pushing block then pushes the lampshade mold retained on the inner wall of the lower mold out of the inner wall of the lower mold, thereby providing convenience for workers to take the mold. However, the injection mold has the characteristic of being easily adhered to the fixed mold plate during the process of ejecting the plastic parts. When the mold is opened, the plastic parts stick to the upper mold plate, which causes the ejection mechanism to fail to work normally. Utility Model Content
