Description of the Invention: [Technical Field] The present invention relates to a method of manufacturing an insole, and more particularly to a method of manufacturing a foamed insole. [Prior Art] Referring to Fig. 1, a conventional method for manufacturing a foamed insole having a cloth layer comprises the following steps: As shown in Fig. 2, in step 1〇1, a large area of foam is prepared in advance. Primitive 1 (). The foam precursor 1G is a hop (ethylene-vinyl acetate copolymer) as a main component. In this example, the thickness D of the foam initial embryo is 47ππτι. As shown in FIG. 2 and FIG. 3, in step 1〇2, a top surface 101, a bottom surface 1〇2, and a surrounding surface 1〇3 of the foam initial embryo are cut to obtain a foam. Semi-finished product 11. In this example, the thickness D1 of the foamed semi-finished product i i was 42 mm. As shown in Fig. 3 and Fig. 4, in the step 〇3, the foamed semi-finished product 11 is cut into a predetermined number of foamed finished products 12 of equal thickness. In this example, the foamed semi-finished product 11 is cut into three pieces of the foamed product 12 having a thickness D2 of 14 mm. As shown in Fig. 5, in step 1〇4, the two fabrics 2 are attached to the top and bottom surfaces of the finished foam product 12, respectively. As shown in Fig. 6, in step 1 〇5, the foam finished product 12 (see Fig. 5) that has been attached to the two fabrics 2 is cut into a plurality of square insole initials 13 〇 200810915 with Figure 7 As shown in Fig. 8, in step 1〇6, the insole 13 of each insole is cut to obtain two equal volumes of the foam section 14. In this example, the thickness D3 of one side of the foam chip was 5 dirty, and the thickness D4 of the opposite side was 9 nm. In step 107, the foam section is heated. As shown in Fig. 8 and Fig. 9, in step 1〇8, the softened foam section 14 is placed in the semi-finished molding die 3. In step 109, the foam section 14 is subjected to mold cooling in the semi-finished molding die 3, and the insole half 15 is obtained after the molding. In step 110, the flash of the insole semifinished product 15 is cut to produce a finished insole (not shown). Although the existing manufacturing method shown in FIG. 1 can produce an insole, the practical disadvantages are still urgent to be improved: The above manufacturing method is quite complicated and has the disadvantages of high working hours and, importantly, As shown in Figures 8 and 9, the foamed section 14 of the square shape is first placed in the semi-finished molding die 3 to be cold-pressed into the insole semi-finished product 15' as shown in Fig. In this way, the amount of flash required for cutting will be quite large, which will not only increase working hours, but also have the disadvantage of wasting foaming materials and fabrics. In today's environmental awareness and limited resources, it will be serious and urgent to solve. The problem. Second, the manufacturing method is to prepare a large-sized foam primordial 1 () as shown in Fig. 2 in advance, and then cut the top surface (8) and the bottom surface of the foam initial embryo 1G! 〇 2, and around the surface called odor, can get a shortcoming of the 200810915 bubble semi-finished product 1 1 foam material as shown in Figure 3. Not only does it increase the manufacturing process and working hours, but it also has a waste of hair, such as @6不的鞋塾初胚13 ‘经 =咖的泡沫片片14 (see Figure 7). However, in practice, the J-bubble section has been shaped and presented—from a high-end “type structure. If it is required for different use requirements, it is intended to be in a specific part of the force A 'in the (4) position to find a position to fit a high foam (Figure not Show), but this will greatly increase the manufacturing steps, man-hours and costs, and the disadvantages of poor compatibility. Fourth, in addition, if you want to use the above manufacturing method as a benchmark - with high elastic strength sheet (not shown) In the case of an insole, or a shoe last having a suspension reinforcement (not shown), in practice, the hair (four) W 14 must be directly formed into a shoe that is not attached to the fabric without being attached to the fabric 2 The primordial embryo (the figure is not shown and the hole is in the forefoot part of the boot of the shoe that has not yet been attached to the fabric, or the heel of the shoe is dug for inserting a high elastic reinforcing piece or a shock absorbing piece, and then The fabric is applied in sequence, and the finished shoe last can be obtained by the above steps lG6~nG. However, such a complicated manufacturing process will improve the working hours and costs, and the boring action has the disadvantage of wasting foaming material. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a A method for manufacturing a foamed insole that is simple and saves material. Thus, the method for manufacturing a foamed insole of the present invention comprises the following steps, preparing a pre-twisted thickness, and forming a phase interval and symmetrical with respect to 200810915 a shoe-shaped foam having a top surface and a bottom surface; 2. cutting the shoe-shaped foam body to obtain at least two equal-volume shoe-shaped foam slices; 3. attaching a cloth to the shoe One of the foamed slices is coated on the leather surface, and the heating of the shoe-shaped foam is sliced; 5. The shoe-shaped foam is sliced into a semi-finished molding die; 6. The mold cooling is performed, and the molding is performed. Thereafter, a foamed insole semi-finished product is obtained, and 7. the foamed shoe last semi-finished product is cut to obtain a foamed insole product. The manufacturing method of the invention not only makes the manufacturing process simple, time-saving, but also directly forms The shoe-shaped foam with a 敎 shape can effectively reduce the processing time of the curing process in the subsequent processing and cutting, and can improve the process efficiency, and can greatly reduce the wave of the foam material and the cloth, and has a deep green color. Environmental advantages [Embodiment] The foregoing and other technical contents, features, and advantages of the present invention will be described in the following detailed description of the preferred embodiments of the drawings. In the following description, similar 7L members are denoted by the same reference numerals. It is preferred to refer to Fig. 10, which is an embodiment of the method for manufacturing the foamed insole of the present invention, comprising the following steps: matching with Fig. 12 and Fig. 13 In step 2〇1, a shoe type foam 4 having a top surface w-=42 is formed with a wetness of 200810915 a, and formed with a spacing and symmetrical arrangement. In this example, The shoe-shaped foam* has a side dimension di of 18 mm and a thickness of 12 sides on the opposite side. ... In terms of handling, the pre-designed foam molding die 5 4, (10) is used to form the shoe type. Bubble 4. For example, by combining the designed foam into the in-mold space 51' of the cookware 5, the shoe-shaped foam 4 having different thicknesses formed at a specific position as shown in FIG. 12 can be obtained, or alternatively, The figure 1 is used to calculate the different types of the in-mold space 5 丨, and a shoe-shaped foam 4 which is highly tapered from the south end side to the lower end side is obtained. Thereby, the present invention can directly produce the leather 5LU body 4' having different thicknesses at the limb position as shown in FIG. 12 by using the mold 5 having the in-mold space 特定 of a specific shape, which is different from the existing manufacturing method, and is intended to be in a specific part. Increasing the thickness b" at this specific position to additionally fit - high foam, can achieve the effect of increasing the thickness. Furthermore, as shown in S1 15, the present invention can provide at least a shock-absorbing reinforcing sheet 6 or at least one high-strength reinforcing sheet (not shown) into the bubble forming cooker 5 in practice. Directly molded into a shoe-type foam (not shown) with a high-elastic reinforcing sheet, or a shoe-shaped foam 4 with a suspension-reinforcing sheet 6, or even a shock-reducing sheet and high elasticity a shoe-shaped foam (not shown) of the reinforcing sheet.

The adhesive and treatment agent used are described in detail. The paste prior art is therefore no longer in step 204, but is to heat the shoe-shaped foam chip 40 to which the fabric 10 200810915 7 has been attached as shown in Fig. 14. In the preferred embodiment, the shoe-shaped foam section 4 is heated by a baking machine (not shown). As shown in Figs. 14 and 17, in step 2〇5, the softened shoe-shaped foam chip 40 is placed in a cavity 81 of the semi-finished molding die 8. In practice, a plurality of limit pins 811 arranged at intervals may be disposed in the cavity 81 of the semi-finished molding die 8 so that the shoe-shaped foam segments 4 are less likely to be offset and can be accurately accommodated. The cavity 81 is in the cavity. In the preferred embodiment, the three limit pins 811 are spaced apart from each other to form a front side of the body and the two side edges of the shoe, so as to form a triangle=set relationship and securely wrap the limit. The shoe type foam was cut into 4 pieces. Since the limit pin 811 is provided in the semi-finished molding die 8 as a prior art, the detailed structure and composition thereof will not be described herein. In step 2, 6, mold cooling is performed, and after finalizing, a foamed insole semi-finished product 400 as shown in Fig. 18 is obtained. In step 207, the overflow of the foamed insole semi-finished product is cut to produce a foamed insole product (not shown). In summary, the step 201 is mainly to form the shoe-shaped foam 4 having different thicknesses at a specific position as shown in FIG. 12 by the in-mold space 51 of the foam molding die 5, or As shown in Fig. 11, a shoe-shaped foam 4 which is highly tapered from the high-end side to the lower end side is shown. The main difference between the shoe-shaped foam 4 and the shoe-shaped foam 4 is that the two 4 and 4 are different in thickness depending on the design difference of the in-mold space 51 of the foam molding die 5, However, the shoe-shaped foam 4 can also be processed in the same manner through the above steps 2〇2 to 2〇3 to obtain a shoe-shaped foam section 4〇 as shown in FIG.卜200810915 Material 7 is attached to the foam section 4〇, and then through step 2〇4~2〇6, the foamed shoe last semi-finished product as shown in Fig. 18 can be obtained, as compared with the figure The manufacturing method of the foamed shoe last of the present invention is simpler than the existing manufacturing method.
