Abstract

The invention relates to the field of shoe preparation, in particular to a preparation process for integrally formed shoes, which mainly solves the problem of poor connection firmness between the upper of the shoe and the sole in the prior art, and comprises the following steps: preparing the mold base of the shoe sole by injection molding; preparing the upper of the shoe ; set the upper of the shoe in the matching shoe last; prepare a secondary molding mold, which includes an upper mold, a middle mold, a lower mold and a fixing ring, put the shoe sole mold base into the lower mold, and fix the shoe last on the On the upper mold, set the fixing ring on the outside of the upper, and attach the fabric on the outer ring surface of the fixing ring, and finally push the upper mold to move downward and insert it into the through hole; through the secondary molding machine, the secondary The forming mold is vulcanized and heated, so that the sole mold base is foamed and formed; the upper part of the fabric and the connecting piece are welded by ultrasonic welding to form an integrated shoe.

Description

technical field [0001] The invention relates to the field of shoe preparation, in particular to a preparation process of integrally formed shoes. Background technique [0002] Existing sports shoes generally include a shoe upper and a shoe sole. The shoe upper is usually prepared by sewing cut and sliced ​​fabrics and then doing subsequent processing. The preparation process is long and auxiliary. It also increases, and the upper hardness of the cut and stitched sports shoes is relatively high, which cannot be completely fitted with the feet, and it is easy to squeeze and rub the feet and cause discomfort. Therefore, more and more shoe-making Manufacturers use flying weaving technology to integrally form shoe uppers, such as an integrated 3D flying weaving upper and its preparation method disclosed on January 27, 2016 and application number 201610054151.4, which discloses in detail how to integrally form shoe uppers through flying weaving technology. technology, making the ...
