AI Technical Summary
After the rubber is molded inside the mold, it is difficult to demold, especially the rubber located at the bottom of the mold groove, which is prone to sticking to the inner wall.
An easy-to-demold vulcanizing mold was designed. A lifting plate is slidably connected between the inner walls of the molding groove, and the outer surfaces of the four sides of the lifting plate are attached to the inner walls of the molding groove. The lifting plate moves up and down by means of a limit frame and a spring, which facilitates demolding after rubber molding. At the same time, the design of the guide rod and the cut ensures the sliding stability of the pressure plate and prevents sticking.
This makes it easy to remove the rubber from the mold after molding, avoiding demolding difficulties, improving the efficiency of mold use and the integrity of the molded product.
