TW515753B - Method of injection-molding polyethylene shoe sole having bi-hardness - Google Patents

Abstract

This invention provides a method of injection-molding a polyethylene shoe sole having bi-hardness, comprising the steps of: (1) injection-molding a dual-color, dual-density shoe edge bock by a dual-color injection-molding machine; (2) placing the block into a mold; (3) injecting and enclosing the block with a single color, single density material; and (4) opening the mold. Adoption of the above four stops solve the problem of color overflowing found in former shoe soles made by injection-molding of shoe edge blocks having different colors. Hence, this invention truly is a very practical method of injection-molding a polyethylene shoe sole having bi-hardness.

Description

丄 J V. Description of the invention (1) The present invention provides a method for injection of a double-hardness polyethylene sole; specifically, refers to a method of using (1) · two-color injection machine to shoot two-color dual-density shoe soles Shunji: 丨 (2) Steps of inserting the mold; (3) · Same color and same density material injection package = two 4, (4) · core-opening step · 'four manufacturing steps to solve the overflowing color generated when soles shot different color shoe blocks in the past Problem person. $, As the level of modern technology combined with plastic injection molding technology continues to increase, plastic injection molding technology has become one of the most important high-tech industrial technologies at present, and the footwear products generally seen today are even more sublime rubber technology. The main industry in China, however, because footwear plastic injection V and production methods are different, so the shoe plastic injection technology is the result of Xing Yi ^ ^ has become the most important issue for adopters; therefore, mIZ hair has a better The effective injection molding technology has already become a problem that clothing manufacturers want to overcome, and the mouth presented in the above content is also the motivation of the inventor of this case to develop this case. The most common injection molding method for footwear polyethylene plastics in general is generally based on 2 (1) · injection molding of shoe block; (2) · step of inserting molds; (3) · different colors and different densities Material injection step; (4) · moulding step; through the above four steps, a finished shoe sole with a harder shoe block can be produced. 'This custom footwear polyethylene plastic injection molding method has been sold on the market and used for a long time. 'But because of the following problems, it will cause problems that need to be improved by the inventors, here one-analysis and explanation are as follows: First,' because the conventional shoe sole block must use harder polyethylene

515753 V. Description of the invention (2) Only the plastic material can achieve the effect of protecting the sole and increasing the service life. Therefore, the density of the polyethylene plastic material of the general shoe block is different from that of other sole materials. Polyethylene plastic materials of different densities are not easy to blend ^ It often causes the problem of easy separation and fall off of polyethylene soles and shoe soles, which also indirectly reduces the quality and service life of the product. Second, manufacturers of custom shoe soles usually use The shoe soles are made of different-colored polyethylene plastic materials to achieve the overall design sense and dazzling appearance. However, because the shoe soles and other soles are shot separately from the front and rear, so-when other shoe materials are shot After molding and foaming, the periphery of the shoe block will be mixed with Xin to form an overflow material of another material (usually referred to as "overflow" in the industry), which not only affects the overall exquisite feeling of the finished shoe, but also two different colors of polyethylene plastic material The chaotic overflow of colors is the main reason for reducing product quality; therefore, in view of the above defects, we are seeking ideals, practicality and progress. , To be very honest to strive for a goal of improvement. -In view of this, the inventor of this case has carefully considered and accumulated many years of experience in the sales, research and development of various types of footwear plastic injection molding institutions and related footwear injection products. A dual-hardness polyethylene sole injection method that solves the problem of color overflow caused by the injection of shoe blocks of different colors in the past. The primary object of the present invention is to provide a dual-hardness polyethylene sole that can solve the problem of color overflow caused by shoe soles of different colors in the past.

Page 5 515753 V. Description of the invention (3) Injection method, the present invention mainly uses (1) • two-color injection machine to inject two-color dual-density shoe blocks, (3) • same color and same density material In the injection coating step, the above two steps can make the injection result of the shoe block not affected by the double-hardness polyethylene plastic material, and can indeed achieve the purpose of solving the problem of past color overflow. A secondary object of the present invention is to provide a dual-hardness polyethylene sole injection method that can enhance the material combination effect. The present invention uses a shoe block with double density to combine with a polyethylene plastic material of the same density, thereby achieving a combination Those who perform better. First, please refer to the first figure. According to the present invention, a dual-hardness polyethylene shoe injection method includes the following manufacturing steps as its characteristics: (1) • A two-color injection machine emits a two-color dual-density shoe block. Steps: Use a two-color injection machine to shoot shoe blocks with two colors and two densities; (2) • Place in the mold step: Place shoe blocks in the mold; (3) • Injection coating with the same color and density material: Those who inject a polyethylene plastic with the same color and density as the outer layer of the shoe block in the mold; (4) • Mold opening step: Take out the finished product after opening the mold. Regarding the detailed methods and other effects adopted by the invention of this case to achieve the above-mentioned objects, technologies, a preferred embodiment can be listed and illustrated in detail with the drawings. I believe that the purpose, characteristics and other advantages of this invention will be
