When the mold closing and vulcanizing are needed, a system controls a cylinder/oil cylinder (other power mechanisms can be dragged by electricity) to drive the staggered tooth ring to rotate for a certain angle along the axis of the vulcanizing machine base, so that the second meshing tooth of the upper beam is locked with the first meshing tooth of the staggered tooth ring, the mold closing is completed, then the force application cylinder is used for feeding oil into the rodless cavity, the piston rod extends out and applies a certain mold closing force to the mold, and the vulcanization can be started after the mold closing force reaches a set value.

2. When adjusting the mould, the height of mould is uncertain:

when a tire mold is installed or replaced on a vulcanizing machine and the height of the mold is uncertain, a piston rod of a stressing cylinder retracts to the minimum, an upper cross beam drives an upper heat insulation plate and an upper hot plate to ascend, the tire mold is fixed on a lower hot plate of a vulcanizing chamber, the upper cross beam drives the upper heat insulation plate and the upper hot plate to descend to be attached to the upper mold and the lower mold, then a rodless cavity of the stressing cylinder is filled with oil, a rod of the stressing cylinder drives the lower hot plate to ascend through a supporting plate and the lower heat insulation plate, finally the mold and the upper cross beam are driven to ascend, when teeth on the upper cross beam fall at positions between staggered tooth ring teeth (between a tooth 7-1 and a tooth 7-2, between the tooth 7-2 and a tooth 7-3 or below the tooth 7-3), detection signals (a sensor 11, a sensor 12 and a sensor 13) are received, the stressing cylinder stops moving, and mold adjustment is completed.

When the mold closing and vulcanizing are needed, a system controls a cylinder/oil cylinder (other power mechanisms can be dragged by electricity) to drive the staggered tooth ring to rotate for a certain angle along the axis of the vulcanizing machine base, so that the teeth of the upper beam and the teeth of the staggered tooth ring are locked, the mold closing is completed, then the rodless cavity of the stressing cylinder is used for feeding oil, the piston rod extends out and applies a certain mold closing force to the mold, and the vulcanization can be started when the mold closing force reaches a set value.

Finally, it is also noted that relational terms such as first and second, and the like, may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
