Description

Technical Field

[0001] The utility model relates to the technical field of shoemaking tools, in particular to a shoe last which helps to combine a midsole and a heel. Background Art

[0002] Shoe last is a traditional Chinese shoemaking tool. The shoe last is the mother of the shoe and the molding mold of the shoe. The shoe last not only determines the shape and style of the shoe, but also determines whether the shoe fits the foot and whether it can protect the foot. Therefore, the design of the shoe last must be based on the foot shape, but it cannot be the same as the foot shape, because the foot changes in shape, size and stress when it is static and in motion. In addition, the variety, style, processing technology, raw and auxiliary material properties, wearing environment and conditions of the shoe are also different. The shape and size of each part of the shoe last cannot be exactly the same as the foot shape. Therefore, modern shoe last design involves multiple disciplines and requires very high manual skills and experience.

[0003] With the rapid development of shoe shapes, the production of some complex shoe shapes requires not only shoe lasts but also other accessories to be installed on the shoes. For example, high heels also require heels to be installed on the shoes. The shoes and heels are separate. First, they are brushed with glue, and then the heels are glued to the shoes. Finally, the shoe lasts are removed and the heels are locked.

[0004] The existing heel locking methods either use a heel locking machine to nail the heel to the shoe with a threaded nail, or manually install the heel on the shoe by screwing a screw. However, both methods have many disadvantages, such as causing the heel to be installed crookedly or inconsistent in front and back positions, the heel is not locked tightly or the nail is crooked, which will make the shoe and the heel uneven and affect wearing. The heel may also be cracked when tightening the screw, and the shoe is easily deformed if the shoe is taken off the last before the heel is locked. Utility Model Content

[0023] The beneficial effects of such a setting are as follows: the utility model positions and fixes the shoe and the heel through the positioning component on the shoe last and the fixing component on the heel, thus eliminating the tedious process of traditional heel installation, which requires people to apply glue, install the heel, and then use the machine to nail and lock the heel, and there will be no quality problems such as crooked heels, cracked heels, crooked screws, etc., which affect wearing. The shoe last of this structure can help the shoe to be installed and fixed more quickly and accurately, greatly improving the efficiency of shoe production. The traditional shoe last made by machine is changed to a shoe last molded by a mold injection molding machine, and the various positioning positions and installation positions required for the shoe are reflected on the shoe last on the mold.

[0024] It is further configured that a plurality of positioning piles 5 are provided on one end surface of the shoe last body 1 close to the midsole 2, and a plurality of positioning holes 6 matched with the positioning piles 5 are provided on the midsole 2, and the shoe last body 1 is plugged and matched with the positioning holes 6 of the midsole 2 through the positioning piles 5.

[0025] The beneficial effect of such a configuration is as follows: the shoe last is positioned with the midsole through the insertion and cooperation of the positioning piles and the positioning holes, thereby ensuring that the positions of the positioning components and the fixed through holes can accurately correspond.

[0026] It is further configured that the number of the positioning piles 5 and the positioning holes 6 are both three and are distributed on both sides of the fixing through hole 4, one of the positioning holes 6 is distributed at one end of the midsole 2 close to the heel 3, and the other two positioning holes 6 are distributed at one end of the midsole 2 away from the heel 3.

[0027] The beneficial effects of such a setting are as follows: the three-point fixation has a more stable fixing effect.

[0028] It is further configured that the fixing component includes at least one blooming rivet 7, and the blooming rivet 7 is integrally formed with the heel 3. The positioning component includes an impact hammer 8, and the impact hammer 8 passes through the shoe last body 1. The impact hammer 8 is provided with at least one impact head 9 at one end close to the midsole 2. The impact hammer 8 drives the impact head 9 to move. The blooming rivet 7 passes through the fixed through hole 4, and the blooming rivet 7 is deformed by the impact of the impact head 9 and then locked with the fixed through hole 4.

[0029] The beneficial effects of such a configuration are as follows: the flower rivet adopts a deformable rivet, and the end of the flower rivet can be folded in all directions under the action of external forces such as knocking, forming the effect of a baffle with a larger radius. In this embodiment, the flower rivet first passes through the fixed through hole and then forms a fixed connection with the fixed through hole through deformation, so that the heel can be firmly fixed on the midsole. The end of the impact head is spherical in shape and matches the hollow structure of the flower rivet. When the impact head hits the center of the flower rivet, the end of the flower rivet can be folded in all directions. The impact hammer is used to provide potential energy to the impact head, and the impact hammer can be connected to automatic equipment to realize automatic hammering, thereby realizing automated production and processing. This way of installing the heel has the advantages of firm connection and simple structure.

[0031] The beneficial effects of this arrangement are as follows: the flowering mold and the impact hammer are split structures, and the flowering mold is limited in the impact cavity to ensure that the impact head can accurately impact the flowering rivet. The impact hammer needs a larger stroke to give the flowering mold a certain impact potential energy.

[0032] like Figure 2 As shown, it is a second embodiment of the utility model, the fixing component includes at least one fixing column 12, the fixing column 12 is integrally formed with the heel 3, the positioning component includes a heating plate 13, the heating plate 13 is connected to the shoe last body 1 through a fixing screw 14, the fixing column 12 passes through the fixing through hole 4, and the fixing column 12 is integrated with the fixing through hole 4 after the heating plate 13 melts.

[0033] The beneficial effects of such a setting are as follows: the fixing column is also fixed on the heel, and the fixing column is made of a material that can melt at high temperature and solidify at low temperature. In this embodiment, the fixing column first passes through the fixing through hole and then heats the fixing column through the heating sheet on the shoe last body to melt the fixing column. After solidification, the fixing column is firmly fixed to the fixing through hole. This way of installing the heel can make the connection between the heel and the midsole more firmly and will not become loose.

[0034] It is further configured that the positioning assembly also includes an electric soldering iron 15, a spring 18 and a pressure rod 16, and the electric soldering iron 15, the spring 18 and the pressure rod 16 simultaneously penetrate the shoe last body 1, one end of the spring 18 abuts against the pressure rod 16 and the other end abuts against the electric soldering iron 15, and the electric soldering iron 15 is tightly abutted against the heating plate 13 by the pressure of the spring 18 and the pressure rod 16, and the positioning assembly is also covered with a heat insulation protective cover 17 that penetrates the shoe last body 1.
