DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The molding die A of the present invention is shown in the following with reference to the drawings. That is, the molding die A of the present invention is a so-called vertical type (as shown in FIG. 1) in which each component moves vertically and is assembled or disassembled, and a so-called horizontal type in which each component is horizontally moved to assemble or disassemble (as shown in FIG. 1). 2 (shown in FIG. 2) can be applied for injection molding of a non-slip shoe sole. As shown in FIGS. 3 to 6, the mold A of the present invention is mainly composed of an upper mold a and a concave mold b, and the convex mold a is mainly the upper surface of the shoe sole E to be molded. , And a convex portion 2, 2 for pressing and supporting the bottom surface of a base portion 31 of a plurality of fixed type spikes D, D, ... Which are to be fixed in a predetermined portion of the inner surface 1 such as a cavity. · Forming Similarly, the concave mold b is fixed in the concave portion 3 that mainly forms the bottom surface side and the circumferential side of the shoe sole E and a portion corresponding to each convex portion 2 of the convex mold A in the concave portion 3, in other words, fixed in the cavity. The non-permeable holes 4, 4, ... Are drilled in the portions corresponding to the tip side 32 of each fixed spike D. Each of the impermeable holes 4 is fitted with an elastic cushioning member 9 having a recess 8 on the side corresponding to the cavity. Further, each of the impermeable holes 4
Alternatively, channels 6, 6, ... That reach the protruding plate e of the mold A are formed on the bottom surface of each buffer member 9, and the ejector for pressing the bottom surface of each buffer member 9 is formed in each channel 6. 7 is inserted. Each impermeable hole 4 may be a through hole. Therefore, in the cavity of the shoe sole E formed by the convex shape a and the concave shape b, the bottom surface and the tip side 32 of the base 31 of each fixed type spike D are convex a.
Of the cushioning members 9 fitted and supported by the recesses 8 of the cushioning members 9 in the impermeable holes 4 of the recessed mold b and inserted through the channels 6 of the recessed mold b. The upper end or, in the case of the horizontal type shown in FIG. 6, is formed so as to project so that the right end thereof is somewhat exposed in the concave portion 3 of the concave mold b. Then, when the bottom material for molding the shoe sole E is injected into the cavity formed by the convex mold a and the concave part b, the sole material is exposed to some extent in the concave part 3 of the concave mold b due to the injection pressure. The upper end portion of the cushioning member 9 or the right end portion in the case of the horizontal type shown in FIG. 6 is compressed and pushed into each of the impermeable holes 4 of the concave die b. For this reason, the molded sole E retains the shape of the cavity, and the base 31 of each fixed spike D is embedded and fixed at each predetermined portion, and a part of each tip end side 32 thereof is located on the ground contact side of the sole E. The exposed, protruding, non-skid sole can be provided. At this time, each of the buffer members 9 has elasticity enough to be compressed and pushed into each of the impermeable holes 4 by the bottom material, and is formed of a thermoplastic resin different from that of each bottom material. After the bottom material has been injected in this way, the closed convex mold a and concave mold b are opened, and the molded anti-slip shoe sole has the tip side of each fixed spike D as shown in FIG. Although 32 is covered with each cushioning member 9, since each fixed spike D and each cushioning member 9 are not completely combined, they can be easily removed from the tip side of each fixed spike D. . As shown in FIG. 9, the cushioning members 9 cannot be used as they are because they are compressed, but they are melted and molded into a shape that fits into each of the impermeable holes 4 of the convex mold b of the present invention. Can be reused.
