ABSTRACT:
This invention concerns a metal mold for the manufacture of a vulcanized reinforced hose by the compression and vulcanization of an unvulcanized hose in the cavity of the metal mold. This metal mold comprises a movable piece, a stationary piece, and a pair of inner pieces disposed between the movable piece and the stationary piece. The movable piece, the stationary piece, and the pair of inner pieces are severally provided at the inner sides thereof with depressions corresponding to the four equal parts into which the inner surface of the cavity of the metal mold is radially divided so that when the metal mold is closed, the pair of inner pieces are synchronously moved with the movable piece and the stationary piece in the direction of compressing the unvulcanized hose.
