[0002] A rubber sealing ring is a circular rubber product, generally used for leak prevention. It is made of rubber and is used to be installed on various mechanical equipment. It plays a sealing role in a static or moving state under specified temperature, pressure, and different liquids and gases. Rubber sealing rings are processed and produced through molds. A mold is a tool used in industrial production to obtain the required products by methods such as injection molding, blow molding, extrusion, die casting, or forging, smelting, stamping, stretching, etc. There are many types of sealing ring molds. Usually, a cavity is formed by an upper template and a lower template for processing the sealing ring. In existing sealing ring molds, the mold is generally composed of an upper press mold and a lower press mold. When discharging the material, two steps of separating and closing the press film are required. The separation and closing require manual removal of the formed rubber sealing ring, which is not convenient to use.
