Plastic midsole for shoes for women and processing method for plastic midsole

Abstract

The invention discloses a plastic midsole for shoes for women and a processing method for the plastic midsole. The midsole consists of a forefoot part and a heel part, wherein the forefoot part and the heel part are integrated into the midsole of which the shape is similar to that of a foot; the forefoot part is formed by laminating multiple layers of paperboards, and a cotton web formed by staggering cotton threads is attached to the lower surface of the forefoot part. The plastic midsole for shoes for women is strong in structural strength, and compared with the conventional midsole for shoes for women, the plastic midsole has the advantages that the lateral surface of the injection-molded midsole is smooth, and during injection molding, required preformed shoe lace openings can be synchronously processed without performing grinding polishing and causing the appearance problem of damage to the lateral surface of the midsole; moreover, the positions of the preformed openings can be corrected at any time by regulating the positions of plastic square blocks, so that modification requirements in a designing and manufacturing process of modern shoes for women can be well met.

Description

technical field [0001] The invention relates to the field of shoemaking, in particular to a plastic midsole for women's shoes and a processing method thereof. Background technique [0002] Women's shoes generally include vamps, soles, and many women's shoes also include shoelaces and other decorations. The sole of women's shoes generally includes three layers, from the bottom to the top are the outsole, the midsole and the insole. [0003] For women's shoes with shoelaces, during processing, it is necessary to fix the bottom of the shoelaces between the midsole and the outsole of the shoe. In order to realize the above-mentioned processing, the existing method is to first cut out the cardboard with the shoelace reserved opening, and then carry out alignment and bonding of the cardboard and the midsole of the shoe manually. After the above-mentioned alignment and bonding process is completed, because There are errors in manual alignment, and it is necessary to grind the sid...

Problems solved by technology

In order to realize the above-mentioned processing, the existing method is to first cut out the cardboard with the shoelace reserved opening, and then carry out alignment and bonding of the cardboard and the midsole of the shoe manually. After the above-mentioned alignment and bonding process is completed, because There are errors in manual alignment, and it is necessary to grind the sides of the fitted shoe midsole to make the sides of the shoe midsole smooth and consistent. However, such edging operations can easily damage the sides of the shoe midsole, causing the shoe The appearance of the midsole

[0004] The existing shoe midsole is a simple flat package, which is generally made of cardboard laminated layer by layer. It is mostly glued to the cardboard with the shoelace reserved opening, and the structural stability is poor. The shoelace reserved opening needs to be processed in advance, and in the actual design and finalization process of women's shoes, it often needs to be revised many times. Due to structural limitations, it is necessary to modify the corresponding molds used in the cutting equipment for processing shoe midsoles. This will not only increase the modification time, but also increase the modification cost, which cannot meet the actual needs of the rapid development of modern enterprises.
