Description of the invention (Printed by the Consumer Cooperative of the Central Approval Bureau of the Ministry of Economic Affairs. This invention is an EVA two-color dual-hardness combined shoe sole foaming method. It relates to the field of shoe manufacturing technology, especially the method of shoe sole manufacturing. . In the manufacturing design of the soles of sports shoes, in order to meet more ergonomic needs', currently, as shown in the fifth figure, a shoe block (30) is installed on the side of the shoe (40), and the shoe edge The function of the block (3 Q) is made of a material harder than the sole (40), which can maintain the shape of the shoe and make walking more comfortable, while reducing the possibility of injury, but the shoe block (30) is combined with the sole (40) The method of making the system: first make the sole (40)-dig out the side of the sole (40) relative to the preset shoe block (30) to form the interface (41), and then make a harder material The shoe block (30), and the shoe block (30) can be of different colors-the position of the interface (41) of the shoe sole (40) and the opposite side of the shoe block (3Q) are coated with resin and other adhesives … Adhesive the shoe block (30) to the sole (40) to fill the position of the interface (41) to form a complete sole 40), and has two colors, different hardness, the shoe block (30) is exposed on the sole (4〇). However, this method has its disadvantages in manufacturing: 1. The manufacturing process is cumbersome and complicated. The sole needs to be manufactured first (4 0) Dig out 2 (4 1) again. The finished shoe block (3 Q) fills the glue, the process is complicated, and there needs to be time for drying after the glue, and it needs to be carefully positioned to prevent the glue from moving. Therefore, the quantization efficiency is poor .... 2 'Increase the cost. In addition to the manufacturing process and the increased cost, the large amount of adhesive also increases the cost, and for the sake of preservation, the adhesive has better properties, which can be expected to increase. Cost is an inevitable result.

Description of the invention (>-) 3 The bonding effect is not durable. If the resin bonding method is not good in the bonding technology process, it is easy to cause a poor gap between the shoe block (30) and the sole (40), and it must be painstakingly bonded. At the same time, the shoes are worn and worn over the years, and they are more easy to wear. The material is aging due to exposure to sunlight and rain, which causes the defect of poor gluing and instability problems that easily fall off. 4 _Shoe block (30) and sole (40), sometimes set to two colors according to market needs, however The seam block (30) and sole (40) will be prone to seams, and the beauty of the two-color design will be lost. If you spray paint directly on the shoe block (30), it will easily fade and expose the bottom color. The reason is that the inventor studied the spirit of the invention, started research and development, based on many years of professional experience and knowledge, carefully tested and innovated, and then proposed the present invention, in order to improve the lack of knowledge. The main purpose of the present invention is to provide an EVA two-color dual-hardness combined shoe sole injection foaming method, which is mainly composed of a shoe sole block that is formed by plastic covering the sole, the shoe block is made of a harder material, and the shoe sole is made of a softer material. When the shoe sole block is first produced, “cooperating with the plastic injection of the shoe sole into the overmolding, the shoe sole block different in color and hardness from the shoe sole is firmly and integrally integrated with the shoe sole, so that the wear is durable and does not fall off”. In order to allow your reviewers to further understand the features of the present invention, the manufacturing process and the breakthrough effect achieved, the preferred embodiments described below are described in detail with the drawings as follows: (1) Schematic part: The first figure It is a component flow chart of the present invention. _____ 4 This paper size is in accordance with Chinese National Standard (CNS) A4 (210X297 mm) (please read the notes on the back before filling in this page). Explanation (>) The second figure is a perspective view of a shoe sole block of the present invention. The third figure is a perspective view of a shoe sole cover block of the present invention. The fourth figure is a sectional view of a shoe sole cover block of the present invention. The fifth picture is a conventional three-dimensional exploded view of the combination of the shoe sole block and the sole. (II) Figure number part: (10) The shoe sole block (11) the inlay hole (20) and the plastic sole (30) shoe sole block ( 40) Shoe sole (41) interface The present invention relates to an EVA two-color dual-hardness combined shoe injection foaming method. Please refer to the first to third drawings. The process of the present invention is as follows: a: making shoe block: a harder one e VA Plastic [Chinese: Ethyl Acetate Acrylic Copolymer] produces an outer contour of the shoe block (10), and the shoe block (10) also forms two or more end surfaces at the same time in the direction opposite to the shoe. The shape of the embedded hole (1 1) * the shape of the embedded hole (1 1) is not limited; b: insert into the mold Place the shoe block (10) into the preset position of the shoe cavity in the foaming mold; c: prepare the sole plastic: prepare the softer EVA as the sole plastic (2 0); " d: injection coating : As shown in the fourth figure, the sole plastic (20) is injected into the foaming mold, and the temperature is controlled to 160 to 18 CTC, and the time is controlled to be within 5 to 10 minutes, so that the sole plastic (2 0) flows into The mold block covers the shoe sole block (1 0), because the shoe sole block (10) forms an embedded hole (ii), so the fluid of the sole plastic (2 0) forms a "grabbing" effect, and the shoe __ 5 Guan Jiapi (0 ^ 7A (2 丨 0X297mm) —---- I -------- / Yu--1T ------ 1 (please first Read the notes on the back and fill in this page) Printed by the Central Standards Bureau of the Ministry of Economic Affairs, Shellfish Consumer Cooperative, 442 37 1 A7 B7 V. Description of the invention (< / :) The edge block (1 0) is firmly embedded; e: Mold opening: Open the mold to take out the finished product; f. · Finished product: Put the finished product in the tunnel oven to shape it to form the appearance of the third figure. The features of the present invention can be briefly described as follows to understand that the manufacturing method of the present invention has been fully solved. Common disadvantages: 1. Manufacturing Speed, the quantization efficiency is effectively improved. As long as the harder shoe block (10) is made first, and the plastic (20) of the sole is shot and covered, the two-color, double-hard sole is completed, which is more cumbersome than conventional digging. The method of designing and bonding, the present invention has greatly broken through the known shortcomings, shortened the operating process, and naturally, the production is fast and stable, and the industrial efficiency is improved. 2. The combination effect is solid and reliable and durable. Because the shoe edge block (100) is attached to The sole plastic (20) is combined in a semi-fluid state, and the flowing state of the plastic covers the embedded holes (1 1) 'densely contacts the peripheral surface of the shoe block (100), so the binding effect is quite reliable' Durable, wind and rain The shower will not cause the problem of joints falling off, ensuring long-term use. 3. The combination of two colors and two hardnesses is quite natural and not easy to fade. Because the shoe block (10) is pre-formed, it can be made of colored plastic independently, so there is no need to cover it with a spray paint effect. The effect is naturally natural, and it is extremely difficult to overcolor, even if there is a slight defect, you only need to touch up the paint. Easy to maintain two-color aesthetics. 4. Reduce costs. The invention eliminates the manufacturing method of using a large amount of adhesive, and improves the substantial profit by reducing the time cost and adhesive cost of the adhesive process. In summary, the present invention is indeed a groundbreaking invention, due to the novel two-color dual-hardness injection foaming method and ingenious space composition _ 6 The paper size is applicable to China National Standard (CNS) A4 specifications ( 21〇χ297 公 楚) '------- I -------- / ------ Order ------ (t (#Read the notes on the back before filling in this (Page) 442371 5.
