When vulcanization with the tire mold Ma is completed,
The fluid pressure cylinder 44 operates to move the mold driving end block 41 below the tire mold Ma.
Moves in reverse, and the tire mold Ma and the transfer device 32a are connected. When the connection between the tire mold Ma and the transfer device 32a is completed, the fluid pressure cylinder 44 operates in the opposite direction to transfer the tire mold Ma to the center P2a of the carriage device 3a, and then the tire mold Ma. The trolley device 3a on which is loaded moves to the opening / closing position P1 of the mold opening / closing device 6a.

When the carriage device 3a reaches the mold opening / closing position P1 and stops, the cylinder 26 operates and the tire mold Ma is pushed up via the tire mold pushing rod 29.
The dolly 19 via the positioning rod 30 and the block 31.
Float from the first tracks 4a and 4b, and the tire mold Ma floats from the second tracks 12a and 12b, and the tire mold Ma is moved by the positioning rods 27 and 30 and the carriage 19.
Is positioned on the mold opening / closing device 6a.

Then, the vulcanized tire is taken out by a known procedure, then the unvulcanized tire is carried in and shaped, and when the tire mold is closed, the heating and pressurizing medium for vulcanization is introduced inside the tire. The next vulcanization process is started. Thus, the tire mold that has entered the vulcanization process is transported to a predetermined position in the vulcanization station in the reverse order of the above procedure, and the vulcanization process is continued, and the carriage device 3a then finishes the vulcanization process. Move to transport the tire mold.

When exchanging money dies, bladders, etc., the tire dies are temporarily closed without carrying in unvulcanized tires and transferred to the die exchange station 11 by the trolley device 3a for die exchange, etc. After that, the unvulcanized tire to be vulcanized is carried into the mold opening / closing station and then vulcanized.
