Description

Technical Field

[0001] The utility model relates to the technical field of tire production, in particular to a tire bead molding device. Background Art

[0002] The tire bead refers to the part of the tire installed on the rim, which is composed of the bead core and the bead cover. It can withstand the tensile force generated by the internal pressure, and can also overcome the lateral force of the tire during turning, so that the outer tire will not fall off the rim. Therefore, it must have a high strength, the structure should be tight and strong, and not easy to deform. The tire bead needs to be formed by a molding device during the production process. The existing publication number CN209365415U discloses a tire bead molding device, in which a reduction motor is fixed to the right side of the vertical plate through a fixed frame, and the reduction motor drives the first mold and the second mold to rotate through a transmission rod.
