<P>PROBLEM TO BE SOLVED: To provide a method for producing a tire vulcanizing mold which can form an exhaust mechanism which can secure enough exhaust by reduced working processes. <P>SOLUTION: The mold in which the surface 11a of a gypsum mold 11 is transferred is produced by the process in which a cylindrical body 7, which has a slit 8 making a cavity inside 7a communicate with the outside and is formed from a metal the same as a molten metal M, is arranged to make the slit 8 contact the surface 11a of the gypsum mold 11 while an easily disintegrable refractory material P remains packed in the cavity inside 7a, and then the molten metal M is cast on the surface 11a of the gypsum mold 11 and solidified, so that the cylindrical body 7 is embedded in the mold to be produced, the slit 8 is exposed to the tire molding surface of the mold, and the easily disintegrable refractory material P is removed after the solidification of the molten metal M. <P>COPYRIGHT: (C)2012,JPO&INPIT |
