Tire vulcanizing system and mold opening/closing and vulcanizing station therefor

The present invention relates to a tire vulcanizing system in which tire vulcanization, mold change, bladder change, mold preheating, green tire supply, and vulcanized tire discharge are performed, and a mold opening/closing and vulcanizing station therefor. A tire vulcanizing system has a mold assembly M for vulcanizing a tire, which has a bladder assembly Mwhich is supplied with a heating/pressurizing medium, a heating chamber Cat the outer peripheral portion of a tire mold C, and upper and lower heating plates MA and MA of the tire mold, and is configured movably and so as to be capable of overcoming a force to open the mold by means of the pressure in a bladder BL; a plurality of mold opening/closing and vulcanizing stations each of which receives the mold assembly M and opens and closes the same, and has a vulcanized tire unloader a green tire loader and a bladder operating/driving device a changing/preheating station which performs the change and preheating of the tire mold C incorporated in the mold assembly M and a bladder assembly and mold transportation apparatus which reciprocates between these two stations and to transport the mold assembly M. Also, the mold opening/closing and vulcanizing station comprises a base frame a pillar for elevation and guidance, which is erected on the base frame an upper movable plate which can freely be moved vertically by being guided by the pillar and connecting/disconnecting device for connecting and disconnecting the upper movable plate to and from the tire mold assembly M.
