Abstract
Provided are a bisected mold for tire molding that enables manufacturing of high-performance tires and that at a mold clamping, avoids a tire from being pinched to thereby attain a yield enhancement; and a process for manufacturing a tire. Inside a container bisected into upper and lower parts in the state of mold opening, there are disposed a mold for tire molding and, along upper and lower side plates, an unvulcanized tire. After performing vulcanization molding of the unvulcanized tire while changing from this state to a state of mold clamping of sectors and segments split into a plurality of pieces in a circumferential direction of the unvulcanized tire through a driving device and a slide unit means, only the sectors are subjected to mold opening by use of a driving means while maintaining the state of mold clamping of the mold for tire molding and the segments by the driving device and the slide unit means, and subsequently taking the vulcanization-molded tire.
