One end of the exhaust passage 210 of the side plate 200 is connected to the exhaust gap 110 through the first exhaust groove 310, and the other end of the exhaust passage 210 penetrates to the outer surface of the side plate 200 away from the cavity panel 100. A passage for exhaust gas is formed from the inner wall surface of the cavity panel 100 to the outer surface of the side plate 200. Because the inner wall surface of the cavity panel 100 is used for exhausting air and is an exhaust gap 110, the distance between the exhaust gaps 110 is small, and the air between the side plate and the green tire can be exhausted from the exhaust gap quickly; but also can solve the problem that the rubber enters the air holes to form a plurality of rubber burrs on the side surface of the tire.
Further, compare with current segmented mold curb plate: (1) the vulcanized tire has no rubber hair and scars on the surface, and the appearance of the tire is tidier and more beautiful; (2) the problem of exhaust hole blockage is avoided, and the vulcanization efficiency of the tire is improved; (3) for a tire factory needing to remove rubber at the tire side part, the tire side part of the vulcanized side plate with the new structure has no rubber, the rubber does not need to be removed independently, and the production cost of the tire is reduced.
