ABSTRACT:
A metal mold for tire vulcanization comprising a tread pattern mold obtained by piling up and fixing a plurality of laminas in order; the laminas have molding portions corresponding to sectional shapes of a tread portion or an outer surface of a tire, the sectional shapes are obtained by slicing a tire in lamina-shape parallel to an equator plane of the tire.
The metal mold of the present invention can be manufactured efficiently since the provision of working data and the working become easy. Furthermore, the mending of the metal mold resulting from partial defects and the partial change of the metal mold are easy since the metal mold of the present invention is not an integral but laminate construction.
