1. the heat preservation sleeve adopts a non-adjustable and fixed structure, and when moulds with different specifications or heights are exchanged, the middle of the mould can not be preserved with heat (the middle is separated);

2. due to the structural design defect of the heat-insulating sleeve, the temperature outside the heat-insulating sleeve is far higher than 40 ℃, and the heat-insulating effect is poor;

3. the existing heat-insulating sleeve only plays a role in heat insulation when the mold is closed and vulcanized, but does not play a role in heat insulation when the mold is opened (or a vulcanization capsule is straightened), and does not enclose and suck vulcanization smoke (harmful and hot waste gas); the existing tire vulcanizing plants have a large number of tire vulcanizing machines which are all directly discharged into the whole vulcanizing plant, so that the room temperature in the whole tire vulcanizing plant is very high, the smoke concentration greatly exceeds the standard, and the production and operation environments of the vulcanizing plant are extremely poor.
