Concealed combined shoe, manufacturing method and forming mold thereof

The present invention relates to a combined shoe, a method for manufacturing the same, and a molding die, and more particularly, to a hidden combined shoe, a method for manufacturing the same, and a molding die. Background technique

For common shoes, the upper and the shoe body are usually fixed together. In this way, when any part of the shoe is damaged, the entire shoe is thrown away. In addition, fixed shoes are not in line with modern people's pursuit of beauty.

In order to solve the above problems, the industry has designed and manufactured a combination shoe with replaceable uppers. Referring to FIG. 1 and FIG. 2, the shoe 100 includes uppers 5 and 6 provided with a plurality of male buckle bodies 4 and a plurality of corresponding female buckle bodies 2. The shoe body 1 is inserted and assembled. The plurality of female buckle bodies 2 are embedded in the periphery of the shoe body 1, and each female buckle body 2 is provided with a jack 3 exposed on the surface of the shoe body 1 for insertion into the male buckle body 4, and a circular passage is provided on the outer wall surface. The hole 9 is provided with an elastic tooth piece 8 inside to abut the clamping teeth under the male buckle body 4, so that the male buckle body 4 and the female buckle body 2 are fitted to fix the upper 5 and 6 on the shoe body 1; In order to make the uppers 5 and 6 detachable, the outer periphery of the shoe body 1 is also provided with a perforation 7 at a position corresponding to the through hole 9 of the female button body 2 for the button 91 to pass through and abutting on the female button body 2 When the button 91 is pressed, the elastic tooth plate 8 moves inward to disengage the teeth under the male buckle body 4, so that the male buckle body 4 is separated from the female buckle body 2 to replace the uppers 5 and 6.

However, the manufacturing method of the shoe 100 is very complicated. First, because a perforation 7 is provided on the outer side of the shoe body 1, and the perforation 7 must be in common with the through hole 9 of the female buckle body 2, it is difficult to align the two. In addition, to prevent the button 91 from coming out after being assembled in the through hole 7 of the female button body 2, a snap edge 92 will be added at the end of the button 91, and in order to provide the operator with a push, the outer end of the button 91 needs to be set again. For a soft cap head 93, because a button edge 92 exists at the end of the button 91, the cap head 93 cannot be formed integrally with the button 91, otherwise it cannot be pulled out. Furthermore, since 93 soft caps are exposed on the outer surface of the shoe body 1, the overall appearance of the shoe 100 is seriously affected. Summary of the invention
