[0002] The mold for rubber vulcanization processing is used to put rubber into the mold for stamping and heating to make rubber products. The mold for rubber vulcanization processing consists of a base, a processing groove, a cylinder, a top plate, and a pressure plate. When using the mold for rubber vulcanization processing, roll the rubber belt together and put it into the top plate in the processing groove on the base, and then put the pressure plate into the base. Then use the stamping cylinder to squeeze the top plate to apply pressure to the rubber belt, and then heat the mold through a heating device to make the rubber belt vulcanize and fuse together. After cooling, open the top plate, and start the cylinder to push the top plate to take out the rubber product.

[0003] The inventors found in their daily work that when the mold for rubber vulcanization processing is in use, the product made after vulcanization of the rubber is easy to adhere to the processing groove on the mold, making it easy to damage the product when forcibly lifting it with a cylinder.
