[0002] At present, the known vulcanization steam chamber is a closed space composed of an upper vulcanization chamber and a lower vulcanization chamber. Tire manufacturers use their own vulcanization process to pass steam or other media such as nitrogen to keep the closed vulcanization chamber under pressure and heat to meet the conditions for tire vulcanization. During vulcanization, a capsule is set inside the tire blank, and high-pressure steam is injected into the capsule. The expansion pressure of the capsule is used to fill the mold with the outer tire blank. The outer tire vulcanization adopts a gradual temperature increase and low-temperature long-term vulcanization method to allow the rubber to fully flow and transfer heat to ensure the quality of vulcanization.
