れた凹凸マークは鮮明さを欠いていた。(B) Conventional technology Conventionally, after blow-molding sole material such as secondary foaming EVA or RB sponge is cut out following the outline of the sole, it is placed in the space formed by the secondary mold and the upper mold. Since shoe soles were obtained by simply pushing the shoe into the shoe, compressing it, heating it, cooling it to room temperature, and then molding it out, the primary molded sole material inserted into the secondary molding mold was simply pressed entirely by the upper mold. Therefore, the bottom material of the part for the concave and convex marks engraved or protruded on the space surface of the secondary mold is not particularly pressed, and the concave and convex marks formed on the outer surface of the bottom after demolding are clear. It was lacking.

目的とする。(C) Problems to be Solved by the Invention The present invention is a method for forming a secondary molded shoe sole by assembling a secondary mold and an upper mold, and at the same time exposing uneven marks. When pressing, simply by providing a protrusion on the lower surface of the upper mold, the protrusion allows the uneven mark portion provided on the space surface of the secondary mold to be attached to the primary molded bottom near the uneven mark portion. To provide a method that can clearly display uneven marks on the outer surface of a shoe sole by strongly pressing only the material.
