だれた外観を呈する欠点があつた。 However, in this method, a part of the ground-contacting sole molding material enters between the intermediate sole and the side mold when forming the ground-contacting sole, and the intermediate sole and the ground-contacting sole form at the boundary between the intermediate sole and the ground-contacting sole of the completed shoe sole. The grounding soles were interwoven with each other, giving a sloppy appearance, and the boundary between the intermediate sole and the grounding sole was unclear, significantly degrading the appearance. In order to eliminate such drawbacks, Japanese Patent Application Laid-Open No. 53-59559 discloses that the ground bottom forming gap and the upper outer periphery of the ground bottom forming gap are After forming a continuous protruding part molding gap and injecting a grounding bottom molding material into the grounding bottom forming gap and molding a protruding part (flat) around the grounding sole and the upper outer periphery of the grounding sole integrally therewith, Open the left and right side molds, raise the upper mold to release it from the side molds, then lower the last with the shoe cover suspended, close the left and right side molds, and remove the shoe last from the left and right sides. The intermediate sole molding material is injected into the intermediate sole molding gap formed by the side mold and the ground sole, and after the intermediate sole is attached and molded to the lower surface of the cover and the upper surface of the ground sole, the protruding portion is A method has been proposed for manufacturing shoes with two-color soles that eliminates . However, according to this method, after forming the ground sole, and before forming the intermediate sole forming gap, there are steps of opening the left and right side molds, raising the upper mold, lowering the last, and closing the side molds. This, combined with the fact that the grounding sole is held solely by the grounding-bottom recess, means that during these steps,
The grounding sole is separated from the concave part of the grounding sole mold, and as a result, there is a drawback that the protruding part integrally molded around the upper outer periphery of the grounding sole is tucked into the intermediate sole molding gap, and as a result, the intermediate sole molding When molding an intermediate sole by injecting the intermediate sole molding material into the gap, a part of the intermediate sole molding material is between the ground sole and the ground bottom mold in the part where the protruding part is tucked into the intermediate sole molding cavity. As in the case of Japanese Patent Publication No. 44-6023 mentioned above, in the completed shoe sole, the intermediate sole and the grounding sole intersect with each other at the boundary between the intermediate sole and the grounding sole, giving a sagging appearance. There were flaws.
