Description

500602 A7 V. Description of the invention (The present invention is a method for integrally forming a shoe table. The present invention is mainly and has the advantages of significantly shortening the manufacturing process to save processing time and cost, and has the advantages of beauty and durability. ^ Press, "Shoe table "It is one of the indispensable elements on shoes, and" shoe table "has a midsole and an outsole. The outsole can be in contact with the ground or floor, and the midsole can be in contact with people's feet to make shoes The platform is for people to easily walk or run, so the shoe platform is one of the most important items in people's daily life. / Based on the traditional traditional shoe platform manufacturing method (as shown in Figure 5) (Shown) ,,, it is made of the EVA foam board midsole and the EVA foam board outsole separately, after processing, and then plasticized separately, the respective manufacturing process is as follows: (1) · EVA midsole Process: Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs

The first step is EVA compound / colorant (medium bottom formula drug) _The first step is to use a kneader to mix into an EVA midsole formula (mix eva rubber particles with drugs and colorant) —the first The third step is to cool with an oil hydraulic machine (to be heated and foamed into an EVA midsole foamed board)-the fourth step is to use a skinning machine to peel the EVA midsole foamed board to the required thickness-the fifth step Cut the cut EVA midsole foam into the desired shape for the cutting machine—the sixth step is to use a heating box to heat and soften the cut EVA midsole foam—the seventh step is to use a compression mold The softened EVA midsole is die-formed for cooling and molding-in the eighth step, the die-cut EVA midsole is cut and punched by a cutting machine. ⑵ · EVA outsole manufacturing process: (as shown in Figure 6) This paper size applies to China National Standard (CNS) A4 (210 X 297 public love)

V. Description of the invention (2) The EVA outsole formula drug and EVA pellets / colorants are printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs according to the first to fifth steps of the EVA midsole process. After the die cuts the EVA midsole, it is then glue-composited. The conventional manufacturing process requires 13 steps, so it has the disadvantages of more and more complicated processes. The present inventor has developed a method for making existing soles, which is not perfect in design, but has actively researched and improved it. 'After continuous trials and tests, the invention has finally been developed with practical utility. The main purpose of the present invention is to provide a method for forming a shoe table in a single piece. The system uses EVA rubber particles and color materials to be mixed into a midsole formula, and at the same time, EVA rubber particles and Color Division are mixed into For the outsole formula, the midsole formula is stacked on the outsole formula, and then foamed by the hydraulic press and the mold of the hydraulic press into the upper middle sole and the lower bottom iEVA foam board. The foamed EVA foam sheet is cooled and formed into a mold, and at the same time, it can be finished by trimming. The manufacturing method of the present invention is to use the thermoplasticity of the EVA foam sheet to foam the oil press, and then directly cool the mold with the foaming temperature. 'The invention has the advantages of significantly shortening the manufacturing process and being integrally formed to save processing time and cost, and also has the advantages of being more beautiful and durable.

ϋ n ϋ t— n I As shown in the first figure of the printed agricultural product of the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the present invention is a method for manufacturing a shoe table, which includes the following steps: Step HEVA rubber particles and pigment ( 1〇) (Midsole with f music) is mixed into the midsole formula (i) by the kneader in the second step, which is kneaded and heated to a simmer state (will be -A rubber particle drug color- The materials are mixed together); Gu Congdi, step: the EVA rubber particles and the coloring material (20) (the four-step mixing machine of the outsole music product) are mixed into the outsole formula (2 1) 'It is Kneading and heating into a molten state (the eva rubber particles 5 DUU0U2

Description of the invention (4 Mixing together); Putting the midsole formula (11) on top of the big bottom formula (21) (as shown in the first and second figures); The fifth step is through the hydraulic press and the hydraulic press mold. EVA foamed board with warming and foaming as the middle layer of the upper layer (12) and the bottom layer of the upper layer (22) The time required for cooling molding is about 3 minutes, and the temperature is about i 4 5 C to 1 65. (Between, the pressure is K50 Kg / cm2; the application of the present invention focuses on: the sixth step is to use a compression molding machine to complete the foamed Seoul foam board_cooling molding (as shown in Figures ―3) (Shown) and trimmed at the same time can become the finished product (30) (as shown in Figures-4). The aforementioned EVA is solid at room temperature and has a melting point of about 8 5 to 9 (TC, so it needs to be at high temperature, high temperature The foam bridge is directly foamed. The size of JL foam depends on its foaming factor and mold size. (For example: mold ^: 100 cm x 50 cm x 2 cm 'and foaming factor is 2 times the board size W 〇〇cmX10〇cmX4cm, so the manufacturing method in the present invention is to use the plasticity of EVA foam board after the oil is repeatedly foamed at the temperature at which the foaming is completed (about U = without cooling, .Using its temperature directly to make a finished shoe platform after trimming the house.
