Abstract

To form a fine slit having a width of 0.1 mm or less in each piece of a piece type tire mold, a plate-line shim member having a width of 0.1 mm or less is inserted into a rubber mold when a piece is to be produced, a molten metal such as aluminum is injected into a plaster mold to which the shim member has been transferred and solidified to cast the piece, and the shim member has been transferred to form a slit having a width of 0.1 mm or less in the piece.

After the casting, the shim member 44 is pulled out from the aluminum die 40, whereby a groove width as shown in Fig. 9D can be formed in the vicinity of the die dividing surface 41 of the above-mentioned die 40. Below lmm or 〇. 〇 5_ is a slit 42 with a fine width. Since the slit 42' in this manner is fine in width, the exhaust gas does not intrude into the rubber, so that unevenness on the surface of the tire after vulcanization can be suppressed. The slit 42 is, for example, shown in the area A of the first drawing, and is distinguished by the projection 45 of the shape-reading pattern or the blade 46, and is extended from the portion corresponding to the land portion of the upper tire to the die. The face 41 is divided, and the side is the slit 42A or the slit 42β to be in contact with the die dividing face 41. A slit such as the slit 42A or the slit 42B is particularly preferably: the projection 45 of the tire pattern or the vicinity of the scraper 46 is preferably provided in the shape of the refreshing projection 45 and the scraper 46: : The slits 42A, 42B and the like as described above are provided on the stencil sheet 4. In the above, it is preferable that the slit of the die-dividing surface 41 which is in contact with the above-mentioned die-divided surface 41 is preferably at least 1 mm apart from the die-divided surface 41. If the area B of the <10 map is arranged, it is in the vicinity of the blade 46 and the mold. : As in the near, more ventilated part, it is preferable not to provide a slit.
