となって付着することがなく外観が良好である。In the present invention, the bottom mold 1 is provided with a concave portion 11 for forming a ground bottom at the bottom thereof, and the bottom surface thereof has an uneven design 11 for forming a non-slip design on the ground surface of the ground bottom.
0 is engraved. If the concave and convex designs 110, 110 ... Are formed in an undercut shape, the non-slip design of the ground contact bottom can be embedded in the concave and convex design 110, so when the dummy last 2 and the last 3 are replaced and set after molding the ground contact bottom. In addition, the grounding bottom A does not rise from the molding recess 11 of the bottom mold 1 during grounding bottom molding, and the edge tape molding material sticks out to the outer surface of the grounding bottom and forms a burr when molding the edge tape B. There is no appearance and the appearance is good.

できるので便利である。In the present invention, when the dummy last 2 and the last 3 are replaced to form the secondary molding cavity 02, the midsole molding cavity 03 is formed on the upper surface of the grounding bottom A continuously with the secondary molding cavity 02. Since the edge tape B and the midsole C can be molded at the same time, it is convenient.
In this case, if the shoe cover D is attached to the last 3 in advance,
When molding the edge tape B and the midsole C, the edge tape B
This is convenient because the midsole C and the midsole C can be attached to the shoe cover D at the same time.

テープ部を有する多色靴底が得られる。(Effects of the Invention) The present invention is configured as described above, and when forming the ground bottom A, the forming recess 11 of the bottom mold 1 is used without using a side mold that can be freely opened and closed as in the conventional case. Therefore, burrs are not formed on the sliding surfaces of the side mold and the bottom mold. Moreover, the edge tape B portion contacting the grounded bottom A is the concave portion 1 of the bottom mold.
Since it is formed in the secondary molding cavity 02 which is formed adjacent to the side surface of the grounding bottom 1, the burr is not formed again at the boundary with the grounding bottom A when molding the edge tape B portion unlike the conventional case. . Therefore, the shoe sole obtained according to the present invention is a multicolor shoe sole having a different-colored tape portion in which the boundary between the grounding sole and the edge tape is clear and which has a good appearance.
