Vulcanizing equipment

A vulcanizing equipment, comprising:

• a vulcanizing mold configured to be able to open and close, in which a vulcanizing cavity is formed;
• a vulcanizing bladder suitable for being placed in the vulcanizing cavity;
• a supporting assembly comprising a center rod and a clamping device provided on the center rod, the clamping device being suitable for installing the vulcanizing bladder in the cavity in a sealed manner;
• a heating assembly and a gas circulation assembly provided in the vulcanizing bladder in a stacked manner in an axial direction of the center rod, the gas circulation assembly being suitable for circulating a heating medium gas in the vulcanizing bladder;
• and
• a driving assembly comprising a rotating shaft sleeve provided outside the center rod and connected to the gas circulation assembly,
• wherein the center rod can be raised to contract the vulcanizing bladder, and
• wherein the heating assembly comprises a heater forming a ventilation portion in a vertical direction, a sleeve is provided outside the heater, a height of the sleeve is set to be higher than the heater, which facilitates in guiding the heating medium gas to be collected above the heater and enter the heater, thereby improving a smoothness of the heating medium gas circulation.
