Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a shoe heel mold.

[0002]

[Prior art]

 As shown in FIG. 1, a conventional high heel shoe sole is provided with a metal piece 11 in order to increase the strength of the shoe sole 10. A tubular trunk 12 is provided on the heel of the sole 10, and the metal piece 11 and the trunk 12 are fixedly connected to each other. The shoe sole 10 is formed by placing a metal piece and a base in a mold and injecting plastic so as to cover the metal piece and the base.

[0003]

[Problems to be solved by the invention]

 However, since the heel and the rear pillar 13 of the sole 10 of the high heel have a structure in which the middle end is narrow and gradually increases toward the end, the rear pillar 13 of the conventional heel has at least More than two pieces need type separation (at least). Separation lines 14 are recognized on the sole 10 and the pillar 13 formed by the mold separation. This affects the intuition of the product. In addition, the complexity of the mold structure increases the cost of manufacturing the mold. Accordingly, an object of the present invention is to provide a shoe heel mold that does not increase the structure, does not leave a mark on the rear pillar of the shoe sole after molding, and reduces the cost of the mold.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned object, the heel of a shoe according to the claims comprises a shoe sole having an increased strength, a tube having a spiral hole therein and fixed to the heel of the shoe sole, It consists of a mold part composed of a mold and a female mold. The female has a concave structure for receiving the sole and the tube, and the male has a protruding helical plug. The sole is molded by covering the outside of the sole and the tube with soft plastic. Thereafter, the screw plug and the screw hole provided in the tube are screwed together. The male and female dies can be moved relative to each other, and the shoe sole can be smoothly removed from the dies using the flexibility of soft plastic. This forms a sole with no traces of the mold.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 3 and 4, the heel and the mold of the shoe according to the embodiment of the present invention include a sole 20, a tube 30, and a mold 40. The sole 20 can be made of a piece of metal or hard plastic to increase the strength of the structure of the sole 60.

The tube portion 30 has a spiral hole 31 inside, and the end portion of the tube portion 30 is fixedly bonded (adhesively fixed) to the heel of the shoe sole 20 so that the tube portion 30 and the shoe sole 20 are integrally formed. Become . The mold 40 includes a male mold 41 and a female mold 42. The female mold 42 has a concave shape 421 installed therein. The concave shape is a form corresponding to the shape of the sole. The male mold 41 has a projecting spiral plug 411. The helical plug 411 and the helical hole 31 of the tube 30 are threaded. The sole 20 and the tube 30 are placed in the recess 421, and the outside of the sole 20 and the tube 30 is covered with soft plastic to form a sole. Further, the male mold 41 and the female mold 42 are relatively moved, and the shoe sole 50 is pulled out of the mold and molded.

As shown in FIG. 4, the heel and the mold of the shoe according to the embodiment of the present invention constitute the inner structure of the rear pillar of the shoe sole 50 by the tube portion 30 having the spiral hole 31 therein. The shoe sole 50 is molded by covering with soft plastic. Furthermore, the spiral plug 411 of the male mold 41 and the tube part 30 are connected to each other, and the male mold 41 and the female mold 42 are relatively moved, so that the shoe sole 50 can be smoothly molded by utilizing the flexibility of the soft plastic. Can be extracted from

In the mold 40 according to the embodiment of the present invention, since only the female mold 42 has the concave shape 421 in the form of a single concave shape, there is a mark left on the heel 51 after molding. It does not affect the appearance. The structure of the present invention does not reduce the cost of the mold or increase the material cost. The reason is that the tube section 30 of the present invention can directly replace the main part of the conventional high-heel.

It should be noted that the connection between the male mold 41 and the tube portion 30 according to the embodiment of the present invention is completed by being screwed by the structure of the spiral plug 411 and the spiral hole, and thus the pulling by removing the mold is performed. It is possible to withstand the forces. After the mold is removed and completed, the operation of separating the spiral plug 411 and the spiral hole 31 is easy (just turn the spiral plug off) and, on the other hand, if it is actually implemented, the spiral plug of the male mold 41 of the present invention is realized. 411 has the advantage of practical development in production, as it is possible to carry out the process of automatic coupling and separation from the mold according to the pneumatic equipment (for example, cylinder).

[0010] As described above, the structure according to the embodiment of the present invention is configured such that, when performing the operation, the male mold having the screw stopper and the tube having the screw hole are connected and further covered with a soft plastic. To mold the sole, and then move the male and female molds relative to each other, to smoothly remove the sole from the mold through the flexibility of the soft plastic, and to form a sole with no trace of the mold coming off. In addition, the appearance is improved, and the cost can be reduced.
