Problems solved by technology

Although the existing technology can achieve the purpose of weight reduction through double-density injection, but because the foam layer between the rubber sole and the inner bottom is likely to have the disadvantage of not being firmly combined with the upper, the corresponding density of the foam layer can only be It is controlled within the density range that can be combined with the upper, so it cannot achieve the ultimate in weight reduction

Embodiment 1

[0020] A process for effectively reducing the weight of shoes and boots. The sole structure is from the outside to the inside in order of dense rubber layer outer layer, inner bottom, foam layer, insole, grooves are set on the inner bottom, and then the shoe is molded or injected The surface and the sole are combined, and the specific process steps are as follows:

[0021] Insole filling: Put the main heel and toe cap into the predetermined position of the front and back, then put the filling material into the groove of the insole, use hot melt glue to dispense glue on the front tip, inner and outer ankles, and heel, and then stick to the last;

[0022] Glue brushing: brush white latex on the back and inner side, oven temperature 60-75°C, 3-7 minutes;

[0023] Stretch shoes: the mouth and ear fans are stretched straight, the upper is stretched, the chassis is glued flat and firmly, and the stubble is pressed against the feet;

[0024] Drying: Send the qualified stretch last ...

Abstract

The invention relates to a process for effectively reducing weight of boots and shoes. A sole structure sequentially consists of a tight rubber outer layer, an insole, a foaming layer and a shoe pad, wherein grooves are formed on the insole, then a vamp and the sole are combined through a die pressing or injection process, and technical processes such as insole filling, gluing, shoe stretching, drying and the like are adopted. The insole is changed to a position which is 15mm to 20mm away from the edge, the middle part of the insole is protruded for 8mm to 10mm towards the rubber sole, so that the depth and the space of the rubber sole can be effectively reduced, the groove facing a shoe cavity can be used for storing EVA or other light-weight materials after the shoe is formed so as to achieve a weight reduction purpose, the material arranged in the groove can be set as the shoe pad, and the weight reduction can be optimized.

Description

technical field [0001] The invention belongs to the field of shoemaking technology, in particular to a technology for effectively reducing the weight of shoes and boots. Background technique [0002] Generally, the soles of molded shoes or injection shoes are bonded to the upper by vulcanization of rubber, and the gap between the sole and the upper needs to be filled with rubber to realize the combination of the upper. In order to reduce the weight of shoes and boots, the thickness of the rubber layer is generally reduced by increasing the midsole and reducing the space between the insole and the sole to achieve the requirement of weight reduction. Although the existing technology can achieve the purpose of weight reduction through double-density injection, but because the foam layer between the rubber sole and the inner bottom is likely to have the disadvantage of not being firmly combined with the upper, the corresponding density of the foam layer can only be It is contro...
