。DETAILED DESCRIPTION OF THE INVENTION (a) Technical field to which the invention pertains The present invention relates to a method for inserting a shoe sole material into a space formed by a last mold, a side mold, and a bottom mold, which are formed by fixing a sealing member to the bottom surface. The present invention relates to a method of molding injection-molded shoes, which are formed by injection filling and integrally molding the shoes.
（ロ）従来の技術

（５）に射出して形成されている。(B) Conventional technology Conventionally, injection molded shoes with two-color soles formed by sliding the sole mold up and down are first coated with the sole material of the first color, as shown in FIGS. 3 and 4. The first bottom material is formed by injecting into the space (4) formed by the mold assembly of the last mold (1) fitted with the side mold (21, (21) and the bottom mold (3), and then the second The colored bottom material is formed by lowering the bottom mold (3) and injecting it into the formed space (5).
ところが、この方法により形成される２層底は１色底の
場合よりも重くなる場合が多い。従って、軽量にする為
に２色目の底をスポンジ底にしようとしても、１色目の
底が第３図に示す如く胛被の底面にも形成されているの
で、その厚みだけ薄くなり２色目のスポンジ底の発泡が
制約されてスポンジ層になり難く、余り効果が出ないと
いう欠点を有していた。However, the two-layer sole formed by this method is often heavier than the one-color sole. Therefore, even if you try to make the bottom of the second color a sponge bottom to make it lighter, the bottom of the first color is also formed on the bottom of the cover as shown in Figure 3, so the thickness will be thinner and the bottom of the second color will be thinner. The problem was that foaming at the bottom of the sponge was restricted and it was difficult to form a sponge layer, making it less effective.
又、ボトムモールドの意匠面がラストモールドの底面に
密接すれば、−色目の底の厚みは小さくなるが、胛被の
底面を損傷して底材が中底面に洩れる等の害があり、２
色目のスポンジ底の発泡効果を充分に発揮することはで
きなかった。In addition, if the design surface of the bottom mold is brought into close contact with the bottom surface of the last mold, the thickness of the bottom of the color pattern will be reduced, but there will be harm such as damaging the bottom surface of the cover and allowing the bottom material to leak into the inner bottom surface.
It was not possible to fully demonstrate the foaming effect of the colored sponge bottom.

底を有する射出成形方法を提供することを目的とする。(c) Problems to be Solved by the Invention The present invention is a shoe sole injection molding method in which the sole can be formed by assembling a bottom mold that is located between a last mold and a side mold and can move up and down. A sealing member is fixed to the bottom of the mold, and the side peripheral edge of the sole is formed by mating this sealing member with the sole design engraved on the top of the bottom mold, and then the last mold is lowered. To provide an injection molding method that has a lightweight two-color sole that is comfortable to wear and is integrally molded with a shoelace by injecting a main sole material into a space formed by the sole.

In a method for molding injection molded shoes, a sealing member that matches at least a convex design surrounding the outer periphery of the bottom design engraved on the top surface of the bottom mold is fixed to the bottom surface of the last mold. When the bottom mold is in close contact with the
This is a method of molding injection molded shoes, characterized in that the sole material is injected and filled, and then the second sole material is injected into the space formed by the lowering of the bottom mold and integrally foam-molded.
