TW382589B - Method of integrally producing multi-color midsole - Google Patents

Abstract

A method of integrally molding a multi-color midsole essentially comprises preparing an injection agent having more than two colors by mixing a SBS resin with dyes, simultaneously and separately injecting the injection agents of different color to a mold by injection machines, thereby forming an integral midsole having various colors.

Description

V. Description of the Invention (1) &lt; Technical Field &gt; The present invention relates to a method for manufacturing shoes, and can be made into multicolors in one piece without manual processing. <Background of the Invention> Conventional soles and midsoles are manufactured separately as shown in the first figure), and the adhesive (and the contact surface of the midsole) must be manually adhered to each other using a pressurized machine bottom and midsole. The excess adhesive (super glue) flowing out is scraped off and glued) to exert the adhesive effect, and then the shoes are finished as shown in the second picture). However, since the product has to be pressurized, ejected, and then removed and waited to complete the product, its manufacturing process is so annoying that it takes six to seven to reduce its cost with larger production. Informed person As shown in the third picture, the sole material is first injected into the mold and the midsole material is injected so that they form the sole and each other (shown in the fourth figure) ', and the sole and the midsole can be purchased by consumers. Of course, ‘if the midsole can also be re-created as a new market, the technical problem that is currently the biggest issue ca n’t be shot. Fitting, the above-mentioned shortcomings are also repeated, because after opening the mold, the raw materials can not be closed again, so it is impossible to shoot two factors 0, especially the shoe bottom mold. Powerful Glue) apply gravity soles and wait for the soles and midsoles to be flattened, (such as the second program talents and then will 'shoot the midsole as a different color and multi-color, one, but the color of the color is divided into Completely, or if you want to expand the color of the above two individuals (such as applying to the sole-pressurize, make the contact surface mixture of the sole (powerful processing (such as applying glue, shown in the picture)), and complete the mold design as shown The molding machine will shape the body (such as' in order to increase the consumption and can also be used in the downturn due to technical bonding agent (strongly divided into two shots, so that the original

V. Description of the invention (2) &lt; Brief description &gt; The main purpose of the present invention is to provide shoes with a midsole that can be made into multiple colors at one time without manual processing, so as to increase the chance of shoes to recreate vitality in the depressed market. &lt; Explanation of drawings &gt; The first drawing is a conventional exploded perspective view.

Description of the invention (3) Middle layer (32) Left layer (33) Right layer (34) &lt; Detailed description &gt; 'Mainly includes: An injection molding machine (10): a rotary table (11) and first, second and third injection machines (12), (1 3), (1 4) (as shown in the sixth figure) 'The rotary table (11) has a plurality of upper and lower molds (1 5), (1 6) (as shown in the seventh figure, the sole and the midsole are integrated), and the upper mold (15) There are two entrances (17), (18). The manufacturing process of the present invention is as follows: Mixing (20): The main material is first formulated. The system is TPE (Styrene Butadi -ene Styrene Triblock Copolymer). The basic formula is PHR TPE (SBS) 100 PS 0-20 softened oil 1-50 white. Tobacco 0-20 Stearic acid 0.1-Carbohydrate 0-50 (softening point 6 0-- 1 5 0 ° C), and different color powders to form different color injection agents. Injection (3 0): first pour the main materials (preset three colors) into the first, second and third injection machines (12), (13), (14) respectively, and then the first

J: \ PATENT \ 7264. Ptd Page 6 V. Description of the invention (4) The injection machine (12) injects the injection agent (50%) of the first color into the mold to form a layer of shoe sole (31) 'and Before the sole layer (31) is not cooled, it is turned to the second and third injection machines (13) (14) by the rotary table (11) of the injection molding machine (10) and passed through the upper mold (15). The injection entrance (17) (18) simultaneously injected two colors of injection agent (20%) (30%) to form the left and right layers (3 3) of the upper sole layer (31) above the sole layer (31) 3 4) (The change of the injection ratio of the two different colors of the injection-agent 'makes the boundary formed by the left and right layers (3 3) (3 4) above the middle bottom layer (3 2) can be shifted left and right), In this way, the injection agent is respectively formed in the mold to have a midsole with two different colors as shown in the fourth figure, and can be integrally formed with the sole. Therefore, the present invention has the following advantages as follows: 1. The present invention forms a product only after mixing and injection (as shown in the fourth figure). The overall procedure is completely processed by the machine, without manual processing, which can increase the production volume and reduce the market price. , And improve market competitiveness. 2. Because the midsole is integrally formed, there is no need to go through the processes of flattening, gluing, pressing, adhering, scraping, etc. to shorten the process time, so it can be produced in a larger amount and reduce its cost. 2. The present invention does not need to manually apply the adhesive (strong glue) = the contact surface of the midsole, and it is not harmful to the human body, so it does not worry about the problem that the worker is not easy to find. In addition, the present invention can shoot the middle and lower layers (54) in two or more different colors in the manner described above, so as to increase the appearance and stimulate consumers to buy. &gt; In summary, a multi-color midsole integrated manufacturing method of the present invention can clearly make another breakthrough innovation to the traditional manufacturing method of bottom soles, which is progressive and practical, and is in line with the application for invention patents. I would appreciate your review
