[0002] The vulcanizing machine, also known as a flat vulcanizing machine, a foam plate vulcanizing machine, a rubber vulcanizing machine, or an electric heating type rubber belt vulcanizing machine, works on the principle of vulcanization reaction. The vulcanizing agent and rubber are chemically reacted through heating and pressurization, so as to vulcanize the rubber products. The heating system transfers heat to the vulcanizing chamber of the vulcanizing machine through a heating medium (such as steam or heat-conducting oil), so as to increase the temperature of the rubber and the vulcanizing agent and promote the vulcanization reaction. The main components of the vulcanizing machine include a hydraulic cylinder, a plunger, a sealing ring, a hot plate, a heating element, an electric control box, etc. The vulcanizing machine generally includes a lower die, a middle die, and an upper die. During production, the rubber material is put into the middle die, and then the middle die is moved into the vulcanizing machine. The middle die cooperates with the lower die and the upper die. The vulcanizing machine heats and the hydraulic cylinder works to apply pressure to vulcanize the rubber material. After vulcanization is completed, the middle die is removed, and then the operator takes out the vulcanized product and then puts in the rubber material for production. However, in the process of taking out the product and putting in the rubber material, the vulcanizing machine is idle, which results in low production efficiency. SUMMARY
