V. Description of the Invention α) According to the shoe body generally made of EVA foam material, the structure of the shoe body is formed by integrating the midsole of the midsole with the sole of the bottom sole, and in the shoe The bottom edge is framed and glued with a decorative slat, and the EVA foam material layer of the shoe body has better elasticity and toughness. Its main material composition is a predetermined proportion of EVA (ethylene vinyl acetate resin) and foaming agent. Materials such as and bridging agent are mixed and stirred, and heated and foamed into a layer of elastic foaming material, which is used as the material of the foaming shoe body to provide the comfort of foot wear and increase the elastic shock absorption effect; and the present invention A person had previously filed a patent application for the "Method for Making EVA Foam Shoe Midsole and Its Peripheral Contour" with the Bureau, and was approved and announced by the Bureau (Patent Gazette Bulletin No. 287081), and the patent case was related to a development The manufacturing method of the midsole of the foam shoes, however, the peripheral edge of the foamed shoe sole needs to be framed and glued separately. For the conventional manufacturing method of the trim strip, refer to the application filed by the inventor of the present case. By the Bureau The "Padging Method for the Foaming Shoe Midsole Peripheral Contour Lath" patent case (Patent Gazette Bulletin No. 31 8810), and the patent case has been approved by the United States Patent (US Patent No. 5, 843, 352 No.), and the patent case reveals a reduced proportion of the original slab plaque made of foamed mixed material, and put it into a reduced or equal proportion of hot-press molding or embossing set mold '俾 can be made into finished slat products with embossed roads; however, in practice, the foamed shoe midsole and decorative slat in the conventional patent case method are separately foamed and molded before being planted. Glue synthesizers "there is not only the high cost of the machine mold required for the conventional method of manufacturing foamed shoe bodies", but also its process is more complicated, and it is necessary to study and improve it. Furthermore, the foamed shoes of the conventional manufacturing law The bottom and trim strips are attached to each

The foam is fused into one body, so the slat with embossed pattern will still fall off and not be tightly glued at the gluing position during vigorous exercise, so how to strengthen the overall structural strength of the foamed shoe body, and At the same time, the disadvantages of improving the conventional shoe system law should be further studied and improved by shoe manufacturers. In view of this, the inventor of this case, with his many years of experience in research and development and manufacturing of foamed shoes, devoted himself to research and improvement to improve the above-mentioned shortcomings. After several trials and tests of samples, it was confirmed that the present invention can indeed achieve the expected efficacy. The present invention is finally completed; and the main purpose of the present invention is to provide a method for manufacturing a foamed shoe body, which is prepared by mixing a predetermined proportion of E v A (ethylene vinyl acetate resin) 'foaming agent and bridging agent and other materials Stir, and then expand the foamed mixture to form a long flat foam with heating and expansion ^ 'and cut it into a plurality of equal proportions of the midsole primordial shoe structure, and then use heating equipment to heat these Proportional midsole embryos that are in a high temperature state, or the foamed mixture can be shot or rolled together to form a quantitatively reduced proportion of midsole primary embryos, which is then heated by a high-temperature molding mold and opened. After the mold, the whole body was completely foamed and expanded into an equal proportion of the mid-sole primordial & Constructor '. Then, the equal proportion of the high-temperature mole-like mid-sole primordial and an outsole coated with viscose And one Shoe body elements such as uppers set on the shoe last of shoe presses are 'set together in a molding mold of equal proportions, a set of cementation and compression cooling molding' can be used for instant localization Heating, and the proportioning mold is a mold for integrally pressing the upper, the equal proportion of foamed shoe midsole, and the shoe outsole.

Description of the invention (3) Through the cooling and press-fitting of the spleen foam shoes, the peripheral edge of the midsole is cleverly made into a embossed layer with a embossed pattern, and a decorative layer is formed on the periphery of the shoe. The shoe last of the machine, the bottom mold seat and the two side mold seats of the same shoe 1 bottom-and the miscellaneous rattan-were high-temperature foaming shoe midsole and a foaming shoe midsole. The high-temperature state has a dust sheet layer, and it is made ^ 1 Μ⑽. As for the foamed shoe body of the present invention, it is made of a pair of mold bases which are clamped on the shoe last and are oppositely clamped. : Two ί: The parting line structure of the bottom edge of the set of mold holders corresponds to the structure of the top edge parting line of two = mold bases. Therefore, when the mold is closed, the two-side mold edge dividing line system and the set of molds The bottom edge parting line of the seat clamp is tightly bonded and pressed into a shape structure with an embossed pattern. Then, the mold is pressed and shaped through the two steps of the mold, and then the mold is opened to take out the finished product of the foamed shoe body. Therefore, the manufacturing method of the present invention can improve the shortcomings of the conventional foamed shoe midsole and its peripheral trim strips that need to be manufactured separately and then glued together, and the foamed shoe body made by the present invention can indeed strengthen the shoe body structure. Strength, moreover, the invention can adjust the manufacturing equipment and process according to the quality and fineness requirements of the foamed shoe body to be manufactured, which can greatly save manufacturing costs and man-hours. Therefore, the invention has industrial applications Value and progressive inventions.
