(Please read the precautions on the back before filling out this page.) Yu Yan, the method of forming the multilayer EVA foam sole of the present invention is to first make an EVA material in advance, which has not been cross-linked, foamed and is often stringent. The state of the outsole primordial embryo and an insole primordial embryo that has not been cross-linked, foamed, and is semi-solid. The outsole primordial embryo has a bottom wall, a peripheral wall extending upwardly from the periphery of the bottom wall, and a A flange extending outward from the top edge of the peripheral wall. Then prepare a hot-pressing foaming mold to maintain the reaction temperature. The hot-pressing foaming mold has a lower mold and an upper mold which can be closed with the lower mold. The lower mold has a top surface and a cavity recessed toward the inside. The upper mold has a bottom surface, a module which is free from the bottom surface and corresponding to the mold cavity, and a material-containing ring groove which is arranged on the periphery of the module. Next, the outsole embryo is placed in the cavity of the hot-pressed foaming mold, and the flange is brought into contact with the top surface of the lower mold. And before the outsole primordial embryo has not begun to undergo a crosslinking and foaming reaction, the insole primordial embryo can be placed on the bottom wall of the outsole primordial embryo. Continue to close the upper mold and the lower mold. The insole primordial embryo will be combined with the outsole primordial embryo and squeezed into the material ring groove by the module extrusion. At the same time, the outsole primordial embryo and the insole primordial embryo will be heated and pressed. The reaction temperature maintained by the foam mold can trigger the crosslinking and foaming reactions. After the cross-linking and foaming reaction is completed, the hot-pressed foaming mold is opened instantly 'to obtain a multilayer Eva foamed shoe semi-finished product. Finally, the semi-finished product of the sole is cooled and shrunk, shaped and trimmed to obtain a finished product of the sole. Therefore, the above-mentioned continuous process can be used to achieve the purpose of forming a multilayer EVA foam sole.

Description of the invention (4 Step 2: Prepare a hot-pressing foaming mold 200 that keeps the reaction temperature between 150 ° C and 180 ° C. The hot-pressing foaming mold 200 has a lower mold 2 1〇 And an upper mold 220 that can be closed with the lower mold 210. The lower mold 210 has a top surface 2U, a cavity 2 1 2 recessed toward the inside, and a ring 212 provided on the top surface 211 and ring-shaped outside the cavity 212 The groove 213 of the upper mold 220 has a bottom surface 221, a module 2 2 2 provided on the bottom surface 2 21 and corresponding to the mold cavity 2 1 2 and a material receiving ring groove 223 provided on the periphery of the module 2 2 2. The material ring groove 223 corresponds to the periphery of the mold cavity 21 2. Step 3: Place the outsole preform 10 into the mold cavity 212 of the hot-pressed foaming mold 2 and place the flange 13 on the lower mold. The top surface 211 of 210 corresponds to the groove 21 3. Step 4: Before the outsole primordial embryo 10 has not started the cross-linking and foaming reaction, 'the insole primordial embryo 20 can be placed in the On the bottom wall of the outsole primordial embryo 10, there is a gap I between the outer circumferential surface of the insole primordial embryo 20 and the peripheral wall 12—the inner annular surface. The top of the insole primordial embryo 20 is high above the flange 1 3 The top surface. Five: Refer to the fifth figure for cooperation. When the upper mold 220 and the lower mold 210 are closed and in a first stage state, that is, when the bottom surface 2 2 1 is just pressed against the flange 1 3 —top surface, use The setting of the flange 13 can make a close effect between the upper mold 220 and the lower mold 210, and the insole primary embryo 20 has been slightly squeezed by the module 222, and the gap disappears. As shown in the sixth figure, When the upper die 22 and the lower die 2 1 0 continue to be relatively close to each other and are in a state of a later stage, the flange J 3 is sinked into the groove 213 by the pressing action of the bottom surface 221 and is in a molten state. 'The extrusion of the insole primordial 20 by the module 2 2 2 will produce a combination effect with the outsole primordial 10, and a part of the insole primordial 20 will squeeze into the material ring groove 223.

Description of the invention (5) The reaction temperature can be touched. Step 6: After the cross-linking and foaming reactions are completed, the thermal foaming mold 200 is instantly opened to obtain the “multi-layer m foamed shoe semi-finished product 1” 00. As shown in the seventh figure, the sole semi-finished product 100 has an outsole no and an insole 120 'and 4 outsole 110-the outer peripheral surface still has _ an edge strip 130 formed by the flange ^ 3 〇y Step 7 As shown in the eighth figure, the sole semi-finished product 100 is subjected to cooling shrinkage, cooling and shaping, and the edge strip is trimmed to obtain a sole product 100, which is manufactured by applying the manufacturing method of the present invention. The finished sole 100 has an outsole U0 'and an insole 120' ', and the outsole 110 is firmly integrated with the insole 120. When the outsole 110 and the insole 120 adopt different colors of EVA When the raw materials are used, the finished shoe sole 100 has a multi-level visual effect. To sum up, the method for molding the multilayer EVA foamed sole of the present invention has a foamed sole that can be made into multiple layers and multi-color effects, so it can indeed achieve the purpose of the invention. However, the above are only the preferred embodiments of the present invention.
