Description

Technical Field

[0001] The utility model relates to the technical field of injection-molded shoes, in particular to an injection-molded shoe with an integrally formed upper. Background Art

[0002] Injection-molded shoes are shoes that are made using the injection molding process. The upper and the sole are molded together by injection molding. However, the soles of existing injection-molded shoes are basically made of a single-density injection molding material.

[0003] After searching, the application with patent number 201821853496.7 discloses an injection-molded shoe, in which the sole is formed by injection molding and wrapped around the iron core, so that most of the iron core can be immersed in the sole. At the same time, during the injection molding process, the sole is integrally connected with the upper and midsole by injection molding, so that the sole is firmly connected with the upper and midsole. The gluing process will be affected by factors such as the amount of glue, bonding pressure, pressurization time, and the time interval from gluing to gluing, making it difficult to ensure the connection strength between the glued upper and the sole. Therefore, compared with the injection-molded shoes connected by traditional glue, the connection strength between the upper, midsole and sole in the utility model is higher and not easy to crack. The heel is detachably connected to the sole, so that a new heel can be replaced after the heel is damaged, and the style of the heel can be flexibly selected according to needs without damaging the entire sole;

[0004] The above application document achieves replaceable operations through the setting of injection-molded heels, which is highly practical. However, the injection is still unified injection molding, that is, direct injection molding is carried out using the same material. The bottom of the sole needs to be relatively hard to increase the service life, and the inside needs to be relatively soft to increase comfort. It is difficult for a unified material to meet this requirement.

[0005] Therefore, we propose an injection-molded shoe with an integral upper. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides an injection-molded shoe with an integrally formed upper, which solves the problem that the existing integral injection-molded sole can only be made of one material, has poor injection molding effect and low practicality.

[0007] To achieve the above purpose, the utility model is implemented through the following technical solutions: an integrally formed injection-molded shoe with an upper, comprising a sole structure and an upper inclined surface mounted thereon, wherein the sole structure comprises an upper sole and a lower sole;

[0008] The bottom side of the upper sole is injection molded with a lower sole;

[0009] The bottom of the upper sole is integrally injection-molded with a receiving layer, the upper sole and the receiving layer are injection-molded from a super-elastic foamed low-density PU material, and a nail column of the same material as the receiving layer is arranged at the bottom of the receiving layer;

[0010] The top of the lower sole is provided with a nail groove matched with the position specification of the nail column, and the lower sole is made of CPU material by injection molding.

[0011] Preferably, a nail groove is extruded on the top of the lower sole through a template, and the template specifications are the same as the nail column;

[0012] Among them, the setting of the template is convenient for squeezing the nail groove from the top side, and combined with the setting of the upper nail column, it can increase the contact area between the upper sole and the lower sole during injection molding, thereby ensuring the firmness of the one-piece injection molding.

[0013] Preferably, the bottom of the lower sole is provided with a bottom groove in a cross shape, and the bottom groove is a table-shaped groove recessed in the box;

[0014] Among them, through the setting of the bottom groove, the contact area between it and the ground during use can be increased, the stability and protection effect can be increased, and the texture is simple and easy to be injected into one piece.

[0015] Preferably, a sewing groove located on the inner side of the edge is formed on the top of the upper sole, a sewing hole connected to the sewing groove is formed in the upper sole, and the upper is sewn into the sewing groove through the sewing hole;

[0016] The arrangement of the sewing holes facilitates sewing the sole and the upper slope through the thread body from one side of the periphery.

[0017] Preferably, the lower sole is pre-injected in the mold groove, the template shapes the top surface of the lower sole from the top side, and then the receiving layer and the upper sole are injection-molded above the lower sole in the mold groove to achieve integrated injection molding of different materials.

[0018] The utility model provides an injection-molded shoe with an integral upper, which has the following beneficial effects:

[0019] The one-piece injection-molded shoe with an upper can perform one-piece injection molding of different materials on the sole by step-by-step injection molding through the arrangement of the upper sole and the lower sole on the bottom side, so as to meet the different requirements of the top side and the bottom side, increase practicality while ensuring one-piece efficient injection molding, and solve the problem that the existing one-piece injection-molded sole can only use one material, with poor injection effect and low practicality.
