Then, lower the left-handed ring (13), upper bolster (9), upper hot plate (lO), and upper mold (11), and lower the upper mold (11).
1) is placed on the lower mold (7), and then the fluid pressure cylinder (26) is operated in the extension direction, and the movement is transferred to the bottle (25).
is transmitted to the pressure receiving plate (24) through the pressure receiving plate (24), and the pressure receiving plate (24) is moved to the position shown in Fig. 3 with the rod (17) as the center, that is, it cannot pass vertically between the upper beams (2a) (2a). Then, the fluid pressure cylinder (3) is operated in the extension direction, and the lower bolster (5), lower hot plate (6), and lower mold (7) are rotated to the desired position.
The lower mold (7) is brought into close contact with the upper mold (11) under pressure, thereby vulcanizing the green tire.

できる効果がある。(Effects of the Invention) The tire vulcanizer of the present invention operates the rotation drive means of the pressurizing force holding means as described above, rotates the pressure receiving plate to a position where it can pass between the upper beams, and then drives the upper mold up and down. The means is activated to raise the pressure plate, upper bolster, and upper mold, separate the upper mold from the lower mold, and take out the vulcanized tire from the lower mold. 9 Next, the upper mold lifting drive means is operated to lower the pressure receiving plate, the upper bolster, and the upper mold, and the upper mold is placed on the lower mold. activating the rotation drive means to rotate the pressure receiving plate to a position where it cannot pass between the upper beams; first, activating the pressure means to raise the lower bolster and the lower mold;
Since the green tire is vulcanized by bringing the lower mold into close contact with the upper mold under a pressure of 11 pressure, the upper ring and lower ring (upper mold and lower mold This eliminates the need for the upper ring and lower ring (surrounding the upper and lower rings), and has the effect of allowing the condition of the green tire to be visually observed until just before the upper and lower molds come into close contact with each other.
