Manufacturing technology and equipment of shoe outsole

Abstract

The invention discloses a manufacturing technology of a shoe outsole. The technology comprises the steps that a, a base of the outsole is produced; b, an upper mold and a lower mold of the shoe outsole are prepared; c, a thin film is prepared, and the base or the thin film is coated with a binding agent; d, a base is placed at the bottom of the lower mold; e, the thin film is laid on the lower mold; f, a plastic uptake technology is adopted to enable the thin film on the lower mold to be adsorbed in a cavity of the lower mold; g, heated shoe outsole materials are shot on the thin film in the lower mold; and h, the upper mold and the lower mold are assembled, after cooling, boundary materials are cut off, and a finished shoe outsole product is prepared. Through the technical scheme, compared with the prior art, the manufacturing technology has the beneficial effects that due to the fact that the thin film can be conveniently manufactured into various colors and various patterns can be sprayed on the thin film quite conveniently, the appearance of the shoe outsole is rich and colorful, appearance defects due to foaming are overcome, and the problem that in the vulcanization molding process, rubber and polyurethane are difficultly vulcanized and composited.

Description

Technical field: [0001] The invention relates to a manufacturing process and equipment for shoe outsoles. Background technique: [0002] At present, the outsoles of shoes produced by composite technology are more popular in the market. Generally, rubber and polyurethane are used for composite production. Rubber has a high friction coefficient and good anti-skid performance. Polyurethane is light and breathable. The weight of the bottom is produced by the foaming process, but whether it is rubber foaming or polyurethane foaming, the product will produce a large number of cells, which seriously affects the aesthetics of the shoe outsole. At the same time, the market is more popular. The outer side wall of the sole produces various colors or patterns, and the traditional composite process is to add a spraying process after the whole shoe outsole is made, and spray the required color or pattern on the outer side wall of the shoe outsole. This process will not only pollute the e...

[0002] At present, the outsoles of shoes produced by composite technology are more popular in the market. Generally, rubber and polyurethane are used for composite production. Rubber has a high friction coefficient and good anti-skid performance. Polyurethane is light and breathable. The weight of the bottom is produced by the foaming process, but whether it is rubber foaming or polyurethane foaming, the product will produce a large number of cells, which seriously affects the aesthetics of the shoe outsole. At the same time, the market is more popular. The outer side wall of the sole produces various colors or patterns, and the traditional composite process is to add a spraying process after the whole shoe outsole is made, and spray the required color or pattern on the outer side wall of the shoe outsole. This process will not only pollute the environment, but also because the outer side wall of the shoe outsole is not flat, the spraying effect is very poor, the spraying is uneven, the boundary line of the spraying is not clear, and it is easy to spray to other parts of the shoe outsole

In the traditional compounding process, rubber and polyurethane are difficult to vulcanize and compound, resulting in low product yield
