(Prior art) Conventionally, hard or soft acupressure protrusions with many small protrusions integrally formed on the surface have been provided protruding from the surface of the insole, corresponding to the spring area on the sole of the foot. At this time, the acupressure projections are used to stimulate the spring area of the sole of the foot (i.e., the sole of the foot located directly below the central part of the second metatarsal bone and the central part of the third metatarsal bone, and this part In Oriental medicine, the acupuncture points are called acupuncture points, which function as conduction control systems for various stimuli. No. 52-163130. However, the acupressure protrusions and the insole must be molded separately, and the acupressure protrusions must be attached to the insole, which has the disadvantage of a complicated manufacturing process and high costs.Moreover, the impact pressure during walking or running, etc. As a result, the acupressure projections fell off from the main body of the insole, resulting in a lack of durability.

(Means for solving problems, embodiments) The present invention will be explained below with reference to the drawings.
This invention includes an insole main body 1 made of a cushiony plate-like thermoplastic foam in which soft compounded uncrosslinked rubber layers 21, 21... are laminated on the parts corresponding to the acupuncture points of the sole, and the uncrosslinked rubber layers 21, 21... The uncrosslinked rubber layers 21, 21... are shaped into the shape of the recesses 41, 41... of the mold by compressing them under pressure at room temperature using a mold 4 having recesses 41, 41... on the molding surface corresponding to the shapes. After the insole main body 1 is further heated under pressure, the uncrosslinked rubber laminated parts 11, 11... of the insole main body 1 are plastically deformed along the recesses 41, 41... of the mold. The acupressure protrusions 2, 2... whose surfaces are covered with rubber layers 21', 21'... are projected onto the surface of the insole main body 1, and at the same time, the rubber layers 21', 21'... on the surfaces of the acupressure protrusions are cross-linked. The gist of the invention is a method for manufacturing a shoe insole, which is characterized in that the remaining part 12 of the insole main body 1 other than the rubber layer laminated part is compressed and the foam structure 121 of this part 12 is densified. . In this invention, the constituent material of the insole main body 1 may be a crosslinked or non-crosslinked material as long as it is softened by heating and can be plastically deformed along the shape of the molding surface of the molding die 4 under pressure and compression. Either is fine, and polyethylene, EVA,
Thermoplastic synthetic resin foams such as polypropylene and vinyl chloride, foams formed by adding a small amount of rubber to these synthetic resins, thermoplastic rubber foams such as styrene-butadiene block copolymers, and 1,2-polybutadiene. Examples include the body. In this invention, the uncrosslinked rubber layers 21, 21... can be plastically deformed along the shape of the molding surface of the mold 4 under pressure at room temperature or during initial heating, and are crosslinked. Constructed of materials that can easily increase rebound resilience and mechanical strength. Examples of these constituent materials include general-purpose rubbers such as NR, SBR, IR, BR, and CR, polyurethane rubber, and the like. These rubbers are laminated on the insole main body 1 by adhering a sheet of rubber to the surface of the insole main body 1 or by applying a liquid rubber compound to the insole main body 1 surface. And its thickness is 0.5~3mm
The degree is appropriate; if it is more than that, the acupressure effect of the protrusions 2 will be reduced in the finished product, and if it is more than that, the uncrosslinked rubber layers 21, 2 will be damaged when pressed at room temperature.
1 tends to deteriorate the plastic deformability. The uncrosslinked rubber layers 21, 21 may be of a solid compound, but if a foam compound is used and foamed at the same time during crosslinking, the completed shoe insole will have a foam structure. The foot contact of the acupressure projections 2, 2, . . . becomes even better.

The insole main body 1 prepared as described above is placed between the mold 4 and the opposing mold 5, and is first compressed under pressure at room temperature, so that the uncrosslinked rubber layers 21, 21, . . . 41, 41..., and if the insole main body 1 is further heated in this state (under pressure compression), the insole main body 1 is softened and the uncrosslinked rubber layer laminated portion 11 of the insole main body 1 is , 11... are plastically deformed along the recesses 41, 41... of the mold, and the surfaces are covered with rubber layers 21', 21'...
are projected and molded onto the surface of the insole main body 1, and at the same time, the rubber layers 21', 21', . . . on the surfaces of the acupressure protrusions are crosslinked. At the same time, the remaining portion 12 of the insole main body 1 other than the rubber layer laminated portion is a molded portion 42 other than the concave portion of the mold 4.
In the compressed state, the foamed structure 121 in this portion is partially collapsed and densified by heating. Specifically, the pressure and heating of the insole main body 1 is as follows:
If the insole main body 1 is made of cross-linked EVA, heat at 120℃ to 140℃ for 4 to 5 minutes for 8 to 12 minutes.
Kg/cm 2 is sufficient. The insole main body 1 has rubber layer laminated parts 11, 11 when heated and pressurized by the mold 4.
In ..., the compressed volume is smaller due to the recesses 41, 41... of the molding die than the molded part 42 other than the recesses, so compared to the remaining part 12 of the insole main body 1 other than the rubber layer laminated part. The foamed structure 122 is rough and has good cushioning properties, and this portion constitutes the core portions 2, 2, . . . of the acupressure projections.

(Effect of the invention) As described above, the present invention provides the uncrosslinked rubber layers 21 and 2.
Molding of the shoe insole is extremely simple since the plate-shaped thermoplastic insole main body 1, which is partially laminated with the insole materials 1, is simply pressurized and heated with the mold 4. Furthermore, the core part 22 of the acupressure protrusion protruding from the shoe insole completed according to the present invention has a rough foam structure 122 and maintains cushioning properties. The rubber layers 21', 21'... are covered with rubber layers 21', 21'..., and the rebound resilience of the acupressure projections 2 is strengthened by the rubber layers 21', 21'.... Good acupressure effect on acupuncture points on the soles of the feet. In addition, the acupressure protrusions 2, 2... are integrally molded with the insole main body 1, and the foam structure 121 of the insole main body 1 is denser in areas other than the molded parts of the insole main body 1. Good durability and shape retention.
