多色靴底の成形法が提案されている。(Prior art) Conventionally, as shown in Japanese Patent Publication No. 57-13281, there has been a bottom mold that can move up and down to form the ground contact surface of the sole, and a sight mold that can be opened and closed with a concave edge tape molded around the inner circumferential surface. After injecting the grounding bottom molding material into the grounding bottom molding cavity formed by the dummy last and forming the grounding bottom, close the side mold, replace and set the dummy last and last, and mold the edge tape on the top surface of the grounding bottom. A multi-colored shoe sole is formed by forming a continuous midsole molding cavity with the four parts, injecting a unique midsole molding material from the ground sole into this cavity, and laminating the midsole integrated with the edge tape on the ground sole. A law is proposed.

く低下される欠点があった。However, when this molding method is used, a pad is formed protruding from the sliding surface of the side mold and bottom mold during the ground-contact bottom molding. When injection molding the midsole, a different color is formed again on the contact surface of the side mold and bottom mold, and the appearance is significantly deteriorated at the boundary between the contact surface of the sole and the edge tape. There were drawbacks.

である。In this invention, a recess 11 for forming a grounding sole is formed at the bottom of the bottom mold 1, and an uneven design 1 is formed on the bottom surface of the bottom mold 1 to form a non-slip design on the grounding surface of the grounding sole.
10 is engraved. This uneven design 110.110・
By forming ... into an undercut shape, the anti-slip design of the grounding sole can be formed by cutting into the uneven design 110, so when replacing and setting the dummy last 2 and last 3 after forming the grounding sole, or when forming the grounding sole. At this time, the grounding sole A does not rise from the molding recess 11 of the bottom mold 1,
When forming the edge tape B, the edge tape molding material does not protrude onto the outer surface of the grounded sole and stick to it, giving it a good appearance.
