Welt shoe and injection mold thereof

Abstract

The invention provides a welt shoe and an injection mold thereof, and belongs to the technical field of shoes. The welt shoe and the injection mold thereof solve the technical problems that a welt ofthe welt shoe, a shoe sole and a shoe body are connected unfirmly and fall off easily and the like. The welt shoe comprises a shoe upper and the shoe sole, the welt comprises a main body and a plurality of protrusions, the protrusions are evenly arranged at intervals along the inner side of the main body, the inner side faces of the protrusions are all connected with the outer side of the shoe upper, a passageway enclosed by the main body, protrusions, and the shoe upper is internally filled with a connecting part made from plastic cement, the upper end face of each protrusion and connecting part fixedly is provided with a bar-shaped locking strip, and the shoe sole, the connecting part and the locking strip are integrated; the injection mold can be used for producing the welt shoe with the locking strip. According to the welt shoe and the injection mold thereof, the integrated design of the protrusions of the inner side of the welt, shoe sole, connecting part and locking strip is notonly conductive to improving the aesthetic degree of the welt shoe, but also enhances the firmness of the connection among the welt, the shoe upper and the shoe sole.

Description

technical field [0001] The invention belongs to the technical field of shoes, in particular to a welt injection shoe and an injection mold thereof. Background technique [0002] Shoes are an item worn on the feet to prevent foot injury. The earliest shoes were mostly straw and cloth shoes. Later, with the development of technology, materials such as plastics were also applied to the production of shoes. In the existing shoe-making process, the sole of the injection-molded shoe is generally injection-molded first, and then a cold-bonding process is used to bond the sole and the shoe body. For shoes with welts, after the sole and the shoe body are glued, the welts are glued on the outside of the connection between the sole and the shoe body, which is not only complicated in the process, low work efficiency, but also unsatisfactory in the connection effect. The body is easy to be degummed and separated, and the connection between the welt and the sole and the shoe body is not ...

AI Technical Summary

Problems solved by technology

For shoes with welts, after the sole and the shoe are glued, the welt is glued on the outside of the connection between the sole and the shoe body. Not only is the process complicated, the work efficiency is low, and the connection effect is not ideal. The body is easy to be degummed and separated, and the connection between the welt, the sole and the shoe body is not very firm, and it is easy to fall off. At the same time, there are problems such as unevenness after the welt is pasted, and it does not fit with the shoe body, which affects the quality of the shoe.
