[0037] The tightening assembly 3 further comprises a hydraulic accumulator 3.2; the hydraulic accumulator 3.2 is connected to the tightening cylinder 3.1 through an oil circuit, so as to timely replenish the pressure of the tightening cylinder 3.1 when the tightening cylinder 3.1 is depressurized.

[0038] The vulcanization mechanism also includes a support arm 4, a second connecting flange and a second connecting piece (specifically a bolt); the support arm 4 is arranged on an end of the second sleeve 2.2 away from the first sleeve 2.1, and is connected to the second sleeve 2.2 through the second connecting flange and the second connecting piece; the hydraulic accumulator 3.2 is arranged on the support arm 4.

[0042] If the tensioning cylinder 3.1 is depressurized during the vulcanization operation, the hydraulic accumulator 3.2 will replenish the pressure of the tensioning cylinder 3.1 in time;

[0043] Step S3: when the vulcanization operation is finished, the tensioning cylinder 3.1 is depressurized by remote control, and the first sleeve 2.1 is linked to drive the hot melt mold to retract.

[0044] If it is necessary to complete the vulcanization operation at the next target operation point, the steps S1 to S3 can be performed in sequence.
