Technology for making shoe body with hidden exchangeable upper

Abstract

A technology for making shoe with exchangeable upper includes preparing an upper mould, arranging the sealing part under the upper mould, linking a femal fastener under the sealing part, wrapping theconcave neck of said femal fastener by an elastic membrane, loading the foaming material in lower mould, assembling upper and lower moulds, foaming, demoulding to obtain shoe, assembling upper and heal to the sole, and putting a pad on the sole.

Description

Technical field: [0001] The invention relates to a method for manufacturing shoes, in particular to a method for manufacturing shoes made of plastic. Background technique: [0002] Know the shoe manufacturing method that can replace the upper and heel strap, refer to Figure 1, figure 2 , Its shoe outsole 1 manufacturing method is to first install a predetermined number of female button bodies 2 in the upper mold, and the lower mold cavity is equipped with foam, and the upper and lower molds are used to buckle the foam or the upper and lower molds After being shot together, a shoe outsole 1 can be formed, and the predetermined number of female button bodies 2 can be buried and distributed at appropriate places on the periphery of the outsole 1. A socket 3 is provided on the surface of the female button body, and the socket 3 can be exposed The top surface of the outsole 1 is for a male buckle 4 to be inserted downward. The male buckle 4 is connected to the lifting ears on both si...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned manufacturing method is very complicated, especially a perforation 9 must be drilled on the outside of the outsole 1 of the shoe, and the perforation 9 must be in common with the through hole 7 of the female button body 2, so it is not easy to align. Another disadvantage is that the button After 91 is assembled in the through hole 7 of the female button body 2, in order to prevent it from coming out, a card edge 92 will be added at the end of the button 91, and it will abut against the peripheral wall of the end face of the through hole 7 to obtain positioning. The button 91 must be exposed outside the perforation 9 of the outsole 1 to provide the operator's fingers to press, so the outer end of the button 91 must be inserted into a soft cap 93. It is important that the cap 93 cannot be in contact with the button 91. It is made in one piece, mainly because there is a card edge 92 at the end of the button 91. If it is formed in one piece, it may not be possible to pull the mold. From this we can see that the usual manufacturing process is quite troublesome and the cost is relatively high, and the finished product is not beautiful.
