Disclosed is a supporting-plate-free, self-adaptively mold-adjusting, hydraulic type tire vulcanizing machine, comprising a rack, a transverse beam mechanism, a pull rod mechanism and a mold mechanism. The pull rod mechanism comprises multiple groups of pull rods, and mold locking mechanisms and hydraulic oil cylinders the number of which is the same as that of the pull rods; each pull rod comprises an upper pull rod and a lower pull rod which are detachably connected, the upper pull rod is fixedly connected to an upper transverse beam, and the lower pull rod penetrates through a lower transverse beam and a hydraulic oil cylinder; the mold locking mechanisms are connected to the lower pull rods, and each mold locking mechanism comprises a driving apparatus, a swinging rod, multiple connecting parts and at least one ball pin seat, with the driving apparatus, the swinging rod, the connecting parts and the ball pin seat being connected to one another; and the upper and lower pull rods connect to a position detection apparatus, which comprises a collision block and a limit switch, with the collision block being arranged on the upper pull rod, and the limit switch being arranged on the lower pull rod and electrically connected to an external control system. The present apparatus can reduce the weight and manufacturing cost of the entire machine, improve the reliability of unlocking and locking actions between upper pull rods and lower pull rods, and realize self-adaptive mold adjustment. |
