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.

Abstract: A green tire (G) is formed by stacking a tire component such as a carcass layer (13) on a film (12) which is made of a thermoplastic resin or a thermoplastic elastomer composition and which is disposed on the entire outer circumferential surface of a cylindrical rigid inner die (1) formed of split parts (2). The green tire (G) is placed in a vulcanizing mold together with the rigid inner die (1) and then heated to a given temperature. The film (12) is pressurized from the inner circumferential side and inflated, and the green tire (G) is vulcanized. Thus, unvulcanized rubber of the tire components is pressed toward the inner circumferential surface of the vulcanizing mold and flows in circumferential directions. As a result, volume unevenness of the tire components is corrected. The film (12) which functions as a bladder is tightly bonded to the inner circumferential surface of the tire to become an inner layer of the tire.

Abstract: A dome cover (6) is manufactured by injection molding by steps of: forming a cavity (14) having the shape of the dome cover (6) between an upper mold (12) and a lower mold (13) for an injection molding die (11), providing a gate port (16) for injecting melt resin at a position (of the upper mold (12)) corresponding to the zenithal portion (15) of the dome cover (6), and injecting the melt resin into the cavity (14) through the gate port (16). The resin injected from the center portion (the portion corresponding to the zenithal portion (15) of the dome cover (6)) of the cavity (14) flows uniformly toward the circumference of the cavity (14). Therefore, variations in pressure and temperature of the resin in the cavity (14) are restrained and, consequently, molding irregularity of the manufactured dome cover (6) is restrained. According to the method of manufacturing the dome cover as described above, generation of the partial molding irregularity on the manufactured dome cover is restrained.
