The present invention relates to a sector-type vulcanization mold for a pneumatic tire, which prevents a rubber leakage through a gap between sector-type molds when a green tire is vulcanized by being pressed between the sector-type molds in a vulcanizing process for a pneumatic tire. To this end, a sector-type vulcanization mold for a pneumatic tire, in which a plurality of pieces of sector molds (2) installed on segments (1) are moved to vulcanize a green tire (100) by pressing and releasing the green tire (100), has a structure in which pads (4) are installed on each of the sector molds (2) of the vulcanization mold between contact slope surfaces (2a) of the sector molds (2) to close gaps (3) between the adjacent sector molds (2); the pad (4) is connected to a link lever (8) that is operated by upper and lower hinge shafts (7a, 7b) around a stationary shaft (6) of a rotation lever (5) installed in the segment (1); and the link lever (8) is connected to a push bar (9) that is moved back and forth through the rotation lever (5) according to the back and forth movement of the corresponding segment (1). |
