    摘要: A mold for tire vulcanization comprises a plurality of segments (2) forming respectively a part of a circular interior complementary to land portions and groove portions of the tread portion of a tire product and being separable from each other in the tire circumferential direction, and each of the segments (2) comprising a plurality of pieces (4) forming the said circular interior part and a block (3) supporting the pieces (4), characterized in that each of the pieces (4) comprises a combination of a matrix metal and a core (6) made of a different kind of material which is preferably fitted to a through hole of the matrix metal and has a lower coefficient of thermal expansion than that of the matrix metal. In a method of manufacturing the mold, upon casting the matrix metal, the matrix metal is cast around the core with a higher fusion point than that of the matrix metal. The invention provides a mold for tire vulcanization by which a tire having excellent appearance can be obtained and production of defective tires upon vulcanization can be decreased, and a manufacturing method thereof, without increase of cost.

    摘要: An annular metal mould for forming a tyre tread is constructed by assembling a plurality of metal sector moulds (2) to be separable in the circumferential direction, and all or some of the metal sector moulds (2) are constructed of a plurality of subsidiary parts (3) separable in the axial direction as well as in the circumferential direction. Joining surfaces (14, 15) between the metal sector moulds (2) themselves each consisting of a plurality of the subsidiary parts (3) are formed of contour surfaces having the arbitrary shape of the subsidiary parts.
