ている。2. Description of the Related Art Conventionally, as a method of injection-molding shoes having different colors, Japanese Patent Publication No. 53-21348 discloses that a seal wall is annularly formed on the last and side molds and the outer peripheral portion in which a cover is suspended. The protruding bottom mold forms an edge tape forming cavity in the lower peripheral portion of the cover, and the edge tape forming material is injected into the edge tape forming cavity to inject the lower peripheral portion of the cover. After molding the edge tape on the bottom, lower the bottom mold, and use the last that suspends the cover and the side mold that holds the edge tape, the bottom mold, and the sole body molding mold. A shoe sole body molding cavity is formed, and a shoe sole body molding material having a different color from the edge tape is injected into the shoe sole body molding cavity, and the shoe sole body is integrated with the sole and the edge tape. An injection molding method for shoes having a different color tape to be molded has been proposed.

性が著しく阻害されていた。However, according to this method, an annular groove is formed at the boundary between the edge tape and the sole body by the annular seal wall integrally provided on the bottom mold, and the sole is formed by this groove. There is a drawback that the durability of the shoe sole is markedly deteriorated due to cracks and tears, and the sealability due to the seal wall is insufficient, and the edge tape molding material penetrates inside the annular projection. However, the adhesion between the shoe sole and the cover was significantly impaired when the shoe sole was molded.
