Description of the Invention (Γ ~) " " [Field of the Invention] The present invention relates to a method for forming a sole, and particularly to an EVA foam sole with a low-expansion-rate wear-resistant component. Molding method. [Description of Knowing Skills] It is generally used to make sole materials, such as rubber, eva ... Among them, the rubber material has abrasion resistance and is hardly foamed. Eva can expand and expand, and has the characteristics of light weight and elasticity. If the sole needs to take into account the characteristics of wear resistance and light weight, it must be combined with EVA and rubber. Existing technologies can only use gluing or bonding, or combine EVA that has undergone cross-linking and foaming reactions (that is, it will not foam and expand after being heated) and rubber into the mold to heat. This is related to the difference in the expansion ratios of EVA and rubber that belong to different physical properties after heating. With the existing manufacturing technology, EVA and rubber that have not been crosslinked and foamed can not be directly combined in the mold. [Summary of the Invention] Therefore, an object of the present invention is to provide a method for molding an EVA foamed shoe sole with a low-expansion-rate abrasion-resistant material that can combine EVA and rubber with different physical properties in a mold. Therefore, the EVA foam sole molding method incorporating a low-expansion-rate wear-resistant component of the present invention firstly prepares a low-expansion-rate and wear-resistant embryo material. At the same time, a hot-pressing foaming mold that maintains the reaction temperature and a middle plate that can be removed from the hot-pressing foaming mold are prepared. The hot-pressing foaming mold has a mold and an upper mold that can be closed with the lower mold. The mold has a top surface and a cavity recessed toward the inside. The cavity corresponds to one of the top surfaces and at least a convex ring is formed on the bottom surface of the mold. The color separation ridge can surround all the flower areas. The contour range is less than (CNS) (210 ^ 2 ^ 7 ^ ¾)-

Description of the invention (6) The closing of the outsole embryo 2 0 can be completely filled in the cavity 2 1 2 by the pushing of the module 2 2 2 and the outsole embryo 2 The bottom of 0 is attached to the top of each pillar 111 of the wear-resistant part 11. When the outsole preform 20 is heated and pressurized by the foaming mold 2 00, the reaction temperature maintained can trigger the crosslinking and foaming reaction, and the outsole The primary embryo 20 can be combined with the top of the granule column 111. Step 8: After the cross-linking and foaming reaction is completed, the hot-pressed foaming mold 200 is instantly opened, and a semi-finished EVA foamed shoe sole with a low-expansion-rate wear-resistant component 11 is obtained from the cavity 212. Step 9: As shown in the seventh figure, the semi-finished product of the sole is cooled, contracted, shaped and trimmed to obtain a finished product. And each of the pillars 111 of the wear-resistant part 11 is stretched by the foamed EVA material, which will make the area of one top larger than the bottom and the cross-section of the trapezoidal. The sole made by applying the above steps is a EVA material-based foam sole combined with a grind grinder 11 which has a grind effect, and the wear part 11 has been divided into a plurality of independent parts during the manufacturing process. Particle column 111, and when the wear-resistant part 11 is made of high-density EVA material, the expansion ratio of the particle column i 丨 丨 is almost equal, and the expansion rate of the large-base primordial embryo 20 after heating can reach about 1 5 〇〇 / 〇. Therefore, when the primordial primordial embryo 20 swells, the top of the independent particle column 111 combined with the primordial primordial embryo 20 will be easily pulled, but the bottom of the primordial column u 丨 still maintains the original size, only the distance between them. Becomes larger, causing the particle column u 丨 to have an inverted trapezoidal shape. In addition, the use of the arrangement of the grain columns 111 has a friction effect in addition to generating unique patterns.

After going through the steps as shown in the first figure, the green material 10 ′ and the connecting layer 30 can also produce a large number of granules lu, and a foamed shoe sole product 100 is made as shown in the ninth figure. By using the material of the connecting layer 30, the raw material can be used as a medium for the connection between the embryo material 10 'and the outsole embryo, and the outsole embryo and the attachment layer 30 have the same physical properties. After cross-linking and foaming reaction, they can be fused into one body. The expansion rate of the joint layer 30 can be US%, which is between the embryo material with an expansion ratio of about 10 and the large bottom embryo with an expansion ratio of about 15%. Lu, the middle section of the embryo material 10, is subject to the expansion layer 30 of the connecting layer 30 and the degree of expansion and stretching is small, while the connecting layer 30 corresponding to the top of the grain column 111 is also subject to the high expansion rate of the outsole embryo. It is stretched so that the granules 111 are inverted trapezoidal.
