In order to solve the problem that a central mechanism of a vulcanizing machine in the prior art is complex in structure, the application provides a central mechanism of a tire shaping vulcanizing machine.

As shown in fig. 1 and 2, the central mechanism of the tire shaping vulcanizer in the present application includes a bladder tube 10, a compound cylinder 20, a ring seat cylinder 30, and a tire supporting cylinder 40. The compound oil cylinder 20 comprises a first cylinder body 21, a second cylinder body 22, a ring rod 23 and a cylinder locking assembly 24, wherein the first cylinder body 21 is provided with a first accommodating cavity, one end of the first cylinder body 21 is movably connected with the bag barrel 10, at least one part of the second cylinder body 22 is movably arranged in the first accommodating cavity, at least another part of the second cylinder body 22 is movably arranged in the bag barrel 10, the second cylinder body 22 is provided with a second accommodating cavity, at least one part of the ring rod 23 is movably arranged in the second accommodating cavity, the cylinder locking assembly 24 is arranged on the circumferential side wall of the first cylinder body 21, the outer side wall of the second cylinder body 22 is provided with a locking groove 221, and at least one part of the cylinder locking assembly 24 can enter or exit the first accommodating cavity to lock the second cylinder body 22; the ring seat cylinder 30 is connected with one end of the second cylinder body 22 in the bag cylinder 10, and the ring rod 23 passes through the ring seat cylinder 30 and extends out of one end of the bag cylinder 10 far away from the first cylinder body 21; the tire support cylinder 40 is drivingly connected to the bag cartridge 10 to move the bag cartridge 10 in its axial direction.

When the central mechanism of the tire shaping vulcanizer in the present application is used, because the central mechanism of the tire shaping vulcanizer has the composite oil cylinder 20, it is possible to replace one upper ring and two lower ring cylinders of the conventional center mechanism by the compound cylinder 20, and the second cylinder 22 is a part of the compound cylinder 20, and can play a role of supporting and connecting, and drives the ring seat cylinder 30 to move up and down repeatedly, the second cylinder 22 can be extended and contracted with respect to the first cylinder 21, and when the second cylinder 22 is extended outward with respect to the first cylinder 21, the locking groove 221 of the second cylinder block 22 can be moved to a position of the first cylinder block 21 corresponding to the cylinder locking assembly 24, and after the second cylinder 22 is moved to the position, the locking of the second cylinder 22 is achieved by controlling the cylinder locking assembly 24 to extend into the interior of the first cylinder 21 and into the interior of the locking groove 221 of the second cylinder 22. Therefore, at this time, since the second cylinder 22 is locked by the cylinder locking assembly 24, the second cylinder 22 can no longer move relative to the first cylinder 21, and only the ring rod 23 can move telescopically relative to the first cylinder 21 or the second cylinder 22, so that the tire can be attached and detached to and from the vulcanizer. Also, the cylinder assembly 24 of the present application replaces the conventional locking structure. Therefore, the central mechanism of the tire shaping vulcanizing machine effectively solves the problem that the central mechanism of the vulcanizing machine in the prior art is complex in structure.

In one embodiment of the present application, the first cylinder 21 and the tire support cylinder 40 are both located at the same end of the bladder cartridge 10.

With this arrangement, when the second cylinder 22 moves relative to the first cylinder 21 and the locking groove 221 of the second cylinder 22 moves to the corresponding position of the lock cylinder assembly 24, the lock pin can be controlled to protrude out of the lock cylinder body and the protruding portion of the lock pin can enter the locking groove 221, thereby achieving locking of the second cylinder 22. When the second cylinder 22 needs to be unlocked, the lock pin needs to be controlled to move in the reverse direction, so that the part of the lock pin extending out of the lock cylinder is retracted into the lock cylinder, or withdrawn from the lock groove 221, and the second cylinder 22 is unlocked.

Also, in the present application, one end of the lock pin capable of protruding into the locking groove 221 is a first end, and the other end is a second end, that is, in the present application, the second end of the lock pin is always located inside the lock cylinder body, and the second end of the lock pin has a partition to divide the inner space of the lock cylinder body into two parts of variable volume.
