Description

Manufacturing method of a shoes bottom plate

The present invention relates to a method of making an insole formed or inserted into a shoe sole plate.

In general, men's shoes and other footwear shoe insole is formed integrally with the shoe or manufactured separately and comes in a replaceable structure.

These shoe insoles come in a variety of forms, but conventional ones do not give a sufficient cushioning feeling and are simple and not refined.

The present invention provides a method for producing a shoe insole that can give a sufficient cushioning feeling to such a shoe insole and provide an excellent insole.

The present invention also provides a method of manufacturing a new shoe insole, but to provide a high quality shoe insole

The main constitution of the manufacturing method of a shoe insole according to the present invention comprises the steps of: forming a shape portion 4 including an uneven portion 2 in a sheet 1 of thermoplastic material; The cover plate 5 made of a thermoplastic material having the thickness part 7 which protrudes the shape corresponding to the shape part 4 on the sheet | seat 1, and the injection hole 8 connected to the thickness part 7 is integrally integrated, Forming an attachment surface 9; When the cover plate 5 is coalesced as described above, any one of urethane gel or silicon is injected into the inner space formed by the thickness portion 7 through the injection hole 8 and then sealing the injection hole by high frequency finishing. ; Cutting out the outer circumference of the attachment surface 9 in an iron form; Coating an adhesive on the attachment surface (9) remaining after being cut out into the iron mold; Bonding the attachment plate 10 by placing the attachment plate 10 having the through hole 11 formed on the attachment surface 9 on which the adhesive is applied, and allowing the thickness portion 7 to protrude out of the through hole 11; Fixing the sheet 1 and the cover plate 5 to which the attachment plate 10 is attached to the upper mold 21 of the mold; Injecting a urethane foaming liquid into the lower groove 25 formed in the lower mold of the mold 20; Closing the upper mold 21 so that the urethane foam liquid and the attachment plate 10 are integrally attached to each other; And cutting out the attachment plate 10 according to the shape of the cut 30 cured by the urethane foam, wherein the shape portion 4 further includes a trademark portion 3 representing a trademark. Characterized in that, the fixing plate 15 is formed in the attachment plate 10, characterized in that to fix the attachment plate 10 to the fixing pin 13 protruding to the upper mold (21), The sheet 1 and the cover plate 5 are characterized in that they are made of a thermoplastic urethane (TPU) thermoplastic material.

According to the present invention, it provides a sufficient cushioning that could not be provided in the conventional shoe insole, the appearance is also very excellent to provide a high quality shoe insole.

According to the present invention, it is excellent in feeling and can reduce fatigue even when walking for a long time.

FIG. 1 is a view for explaining integrating the sheet 1 and the cover plate 5 integrally.
FIG. 2 illustrates the covering of the attachment plate 10 on top of the attached cover plate 5 of FIG. 1.
3 is a view illustrating molding by adding a urethane foam material in a mold;
4 and 5 illustrate a shoe insole manufactured according to the present invention.

Hereinafter, the present invention will be described in detail with the accompanying drawings.

As shown in FIG. 1, the sheet | seat 1 is pressurized or vacuum-formed the shape part 4 which has the uneven part 2 and the trademark part 3 in which a trademark is inscribed as needed. The cover plate 5 is placed thereon and integrated with the sheet 1 integrally. In this case, the cover plate 5 is made of a transparent or translucent material.

The cover plate 5 has a shape corresponding to the shape portion 4, has a thickness portion 7 made of a constant height, and incorporates a previously formed structure having an injection hole 8 at the tip.

The sheet 1 and the cover plate 5 are made of a thermoplastic urethane (TPU: thermoplastic urethane) material which is a thermoplastic material. The use of this material provides good adhesion to the floor and prevents slippage when worn, so the selection of this material is also important for the function of the present invention.

When the sheet 1 and the cover plate 5 shown in FIG. 1 are combined and integrally attached, the sheet 1 and the cover plate 5 are integrally formed, and the sheet 1 and the cover plate 5 are united in a shape in which the thick portion 7 rises, as shown in FIG. The surface 9 is constituted and united integrally. The coalescing method attaches by pressing against the attachment surface 9 part.

When the cover plate 5 is coalesced as described above, silicon is injected into the inner space formed by the thickness portion 7 through the injection hole 8, and the injection hole is sealed by high frequency finishing. (9) Remove the circumference of the outer edge

In addition to the silicon, a material of another material that can give a cushion may be injected into the internal space formed by the thickness portion 7. For example, by injecting the double cell, urethane gel and the like so that the inside of the cushion is composed of a good elastic body.

And put the mounting plate 10 on it. A through hole 11 is formed in the attachment plate 10, and the through hole 11 is a through hole that can accommodate the entire circular thickness part 7.

Attachment plate 10 is made of a material such as leather or synthetic leather or cloth and the fixing hole 15 is formed in the four corners.

In this manner, the sheet 1 and the cover plate 5 are integrally formed, and the adhesive plate is applied to the attaching surface 9 thereon, and the attaching plate 10 is attached to the mold 20 shown in FIG. 3. Take the groove (17) formed in the upper mold (21) to fix the fixing hole (15) by inserting the fixing pin (13) protruding on the outer circumference. And urethane foam liquid is put into the lower groove part 25 formed in the lower mold 22, and the upper mold 21 is closed. The lower groove 25 has a heel insole shape formed behind the insole of the shoe. However, the shape of the lower groove 25 can be made in various shapes. For example, the shape of the insole may be made as shown in FIG. 5.

With respect to the urethane foam liquid filled in the lower groove 25, the urethane foam liquid is cured after a certain time by covering the upper mold 21 provided with the attachment plate 10. Then, the upper mold 21 is opened to take out the cured urethane foam.

This results in a shape as shown in FIG.

That is, the urethane foam liquid filled in the lower groove portion 25 of the lower die 22 is hardened by being integrally attached with the attachment plate 10 attached to the upper die 21, so that in this state, The attachment plate 10 is cut along the cured shape of the urethane foam liquid formed in the lower groove 25.

Then, the shape of the insole 30 is formed, a part of the cover plate 5 protruding by the thickness portion 7 is exposed in the portion corresponding to the hoof, and the inside of the state is filled with nymphs such as silicon as described above Becomes

Therefore, since the inside is exposed by the cover plate 5 made of a transparent plate and urethane gel or silicone filling liquid filled therein, it is possible to recognize the trademark portion 3 from the outside while providing sufficient cushioning for the hooves. That provides very comfortable shoes

5 is another embodiment of FIG. 4, wherein the insole 30 is formed long in accordance with the shape of the bottom surface of the shoe. In this case, it is a matter of course that the shape of the lower groove 25 formed in the mold 20 must also be modified to match the shape of the insole 30.
