Description of the invention: [Technical field of invention] The present invention relates to a method for manufacturing a double hard foamed sole, in particular A manufacturing method capable of ensuring that the sole portion of the sole is extended along a predetermined straight line or curve. [Prior Art] According to the soles of sports shoes, the most popular consumer-loving users, the first one has a leg soft foam sole with good softness and elasticity. The manufacturing technology of the bile foam sole: 'After many years of experience Continuous research and development, its technology has been very successful and in the process of continuous research and development and improvement, the research and development direction of the foam sole can be summarized as follows: As a result, only the one disclosed in the domestic patent No. 87120582 . Secondly, only the pattern and color of the upper are changed. It is already inconsistent with the market. The patent can be achieved at the same time. Several kinds of materials are used at the same time. _% Ren is the same as the thermoplastic material of the factory. In the meantime, there are different colors in the adjacent parts of the ground, and the adjacent parts are fixed at the same position, but each of the Hi-like soles has the same multi-color block. In the exact same position, shape 5 1270452 (corrected in the specification of the nickname No. 093丨2丨427) 1 is asymmetry in the left and right feet and mixed colors. Second, in terms of function, the soles disclosed in the No. 9 Coffee No. 337 patent in China, the two injection materials are simultaneously produced in the mold, and the hardness of the two materials is different. The patent axis claims that it can rely on the soles of different hard f in different parts and gradually change its hardness in the soft and hard abutment. In fact, it is manufactured because both materials are The glare is melted, and each of the high-pressure methods is in the same mode, so the soft and hard adjacent parts in each of the finished products cannot be accurately located at the same position. Moreover, since the two soft and hard different materials 'foamed at the same time each have different expansion materials, the shape of the sole is deformed or bent. Third, in order to solve the shortcomings of the two patents mentioned above, the applicant's research and development _ has developed a new technology that can make two-color double-hardness soles, such as the two-color double hardness combination disclosed in the domestic patent No. 87113457. The sole is shot by a foaming method. _ This manufacturer firstly makes a block material with a special color and hardness, and then coats the outer surface of the EVA material with another color and hardness by injection. This can not only stabilize the sole. The location of the last two color blocks, but also has the function of providing better comfort and bonding strength. In addition, another patent No. 91107119 discloses another method for manufacturing an EVA sole having different wear-resistant regions, but the manufacturing method is fundamentally unsuitable for use in the production of 6 1270452 (the amendment to the specification of the patent No. 093121427) There are many different kinds of 葙 夕 〜 〜 接 接 接 接 A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A Revealing the technology, although it has been confirmed, "can (4) her coffee machine; the edge of the singularity of the object (four) 进 进 ( ( ( ( ( ( ( 91 91 91 91 91 91 91 91 91 91 91 91 91 91 91 91 91 91 91 91 91 91 91 91 Therefore, how to improve its process to make it more cost-effective to personnel costs has become an important issue. In addition, the patent case is prepared by pre-forming a piece of test material to prevent the molten material from infiltrating into the edge. However, since the two kinds of bile materials of the dazzling shape are also The diligent side is in the mold, so 'more or less will still make the bond line at the adjacent part of the two different color areas slightly distorted, __ hold as - smooth scale, let alone maintain it in a straight line status. SUMMARY OF THE INVENTION The main object of the present invention is to provide a method for manufacturing a double-hardness (four) foamed sole which has an effect of improving production efficiency and product yield. The second aspect of the present invention is to provide a double hardness EVA foam sole garment method 4 which has the effect of accurately combining the two parts of different colors and hardness. In order to achieve the foregoing object, the invention discloses a double-hardness EVA foam sole 7 1270452 (corrected in the specification of the patent No. 9312 M27). The manufacturing method comprises the following steps: pre-taking EVA as a main component The right amount of material, made of one that has not been cross-linked, foamed but is in the form of a block at room temperature, the first embryo # and - the first money - the second embryo has different color and hardness and the same hair The expansion ratio of the bubble; placing each of the first and second blanks into a mold, and connecting the upper portion (four), so that the first and the first pieces and the adjacent portions thereof are visible from the bottom surface And jointly forming a small finger base shape before foam molding; transferring the temperature to the appropriate jade, and each first first piece is cross-linked and foamed inside; and then opening the mold It is achieved that the first blank is integrated with the second blank and expanded into a predetermined shape and conforms to one of the actual size required for use. DETAILED DESCRIPTION OF THE INVENTION A number of preferred embodiments of the present invention will be described in detail with reference to the drawings. [Embodiment] Please refer to the first figure. The method for manufacturing the double-hardness EVA foam sole of the present invention mainly includes the following steps: · A pre-boiled material (1): Take EVA as the main component The right amount of material is made into a first piece (1〇) which has not been cross-linked, packaged, and is in the form of a solid block at room temperature, and is cut into a predetermined shape; b·Precast blank ( 2): Take the appropriate amount of material with EVA as the main component, and make it into the uncrosslinked, 8 1270452 (corrected in the specification of the patent No. 093丨21427) 'foaming, and at room temperature One of the solid pieces is a second piece (10) and is cut into a predetermined shape, and can be combined with the first piece (10) to form a sole shape before foaming. The second green sheet (10) has a hardness higher than that of the first-thickness sheet (10) but has the same expansion ratio of expansion, and a coloring material different from the first green sheet (10) is previously incorporated in the raw material; c ·Prepare the mold; D-Dry (10), the county first set a cavity with a shape of the sole before foaming (32); d·feed ·· each of the first-mesh (1G) and the second The embryo sheet (10) is placed in the cavity (32) so that its predetermined portion is adjacent to each other, and the first embryo (10) and the second embryo #(10) and their adjacent joints are visible from the bottom surface of the sole. And a total of small-sized sole shape before foaming, · e·foaming: the first and second pieces (1〇) (2〇) plus /JKL of the inside of the mold (30) Pressurizing to a suitable working temperature and pressure, and triggering the first embryo (10) to pass through and foaming in the interior of the first embryo (10) for a suitable period of time; Obtaining the finished product: Opening the mold (30), the first blank piece (10) and the second green piece (20) are integrated into one body and expanded into a predetermined shape and the actual use ruler 1270452 (the case number) Dijon 9 Correction of the specification of Patent No. 3121427) Inch leather bottom (40) finished product 'and the sole (40) has a soft region (41) corresponding to the foot portion and having a lower hardness, and corresponds to the arch portion and has a hardness One of the high elastic areas (42). In each of the foregoing operation steps, since each of the first green sheet (1〇) and the second green sheet (20) are placed in the solid mold before being placed in the mold (30), and are crosslinked and foamed. During the process, it maintains an ambient temperature between 130 and 180 degrees Celsius without completely transforming the two into a molten state. Therefore, each of the first and first embryos can be made (10). (2〇) In the process of foaming and joining together, the finding of the adjacent portion (10) of the two is always maintained, and the phenomenon that the adjacent portion (43) is distorted occurs. Moreover, since the adjacent portion (43) between the soft region (41) and the elastic region (42) is extremely accurate and does not cause distortion or flashing, the sole (40) manufactured by the method has an appearance. , which can be designed in advance to have different colors, and the adjacent portions (43) of the two colors extend along a smooth curve with a change (as shown in the second figure), or even the adjacent portion ( 43) Designed to extend along a straight straight line (as shown in the third figure), so that the sole (10) has a different appearance from the conventional one, and after the foaming is completed, there is no need to perform an additional trimming of the scrap waste. action. Another creative focus of the uranium case is that the first and second pieces (10) (10) are adjusted to have the same expansion ratio so that the two are Before and after the process of jointing, foaming and mass expansion, the adjacent part 10 1270452 (corrected in the specification of the patent No. 93112227) can be maintained, and the joint portion (43) is flat, in particular, the adjacent portion (43) is located At the side of the sole (10), and the difference in size between the first and second pieces (10) and the second piece (10) before foaming is quite different. In order to achieve the above, each of the soft region (41) and the elastic region (42) have different hardnesses but have the same expansion ratio, and the sole (10) is prevented from being deformed after the sole (10) is formed. Therefore, the first and second The embryo sheet (10) (10) can be set to contain the main components listed in Table 1 below. Table I··

The second embryo (10), or, the shoe sole (10) is subjected to a further step of molding, which is to produce the finished product of the county sole (10), and then insert another mold having a specific cavity shape (not shown) In the middle, and after a molding process of heating and pressurization again, take it out. It should be emphasized here that the 'this-molding step is not for removing the waste, but for the existing shape of the sole (10), and then the _-finishing procedure is used for the sole 1270452 (the specification of the patent No. 093121427) Correction) (40) The peripheral edge of the perimeter 'molds the finer surface of the surface to make it look more special. After considering the subsequent molding process, the overall hardness of the sole (40) is much higher than that before the molding material. Therefore, it is necessary to adjust the first and second in the manufacturing process. The components of the green sheet (10) (20) are increased in expansion ratio, for example, the hardness after foam molding is reduced to 40, respectively. With 55. , 俾 so that even after the subsequent molding step, each of the soft region (41) and the elastic region (42) can be maintained at 55, respectively. With 65.
