摘要： An annular mold having a molding surface for forming a tread pattern of a tire is divided, at least in the peripheral direction, into plural pieces. The plural pieces are disposed adjacent to one another via adjacent surfaces, which are peripheral direction division surfaces, so as to form the annular mold. Substantially an entire molding-surface-side side edge portion of each adjacent surface of the piece is cut-out at a narrow width such that a gap for air venting is formed. Thus, at a low cost, a mold for molding a tire is provided in which there is no spewing, and air can always be reliably vented without a need for applying a vacuum.

摘要： An annular metal mold portion forming a tire tread is constructed by assembling a plurality of sector metal molds 2 severed in the circumferential direction, and all or some of the sector metal molds 2 are constructed of a plurality of smaller parts 3 severed in the axial direction as well as in the circumferential direction. Joining surfaces between the sector metal molds themselves each consisting of a plurality of smaller parts are formed of contour surfaces in arbitrary shape of the smaller parts. These contour surfaces are such curved surfaces that at every location a radius of curvature is 5 mm or larger and an inclination angle of a tangential plane with respect to a tire axis is 80 degrees or less.
