Problems solved by technology

[0002] Existing shoe soles generally include a wear-resistant sheet and a foam structure. The traditional manufacturing method of this type of shoe sole is post-lamination combination, that is, the formed wear-resistant sheet is bonded with the stretchable film and the formed foam structure. At the same time, the traditional production method has a large number of workers, is easy to be messy, has a long process, is not fixed in the production cycle, and has low work efficiency. stable, difficult to control

Embodiment 1

[0029] After cleaning the 3mm thick TPU wear-resistant parts, put glue into the mold, put 0.2mm thick TPU thermal adhesive film into the mold to cover the bottom of the mold, close the frame film, and then heat the mold at 35°C for 20-40min. Pump the air in the mold for 10-25 seconds, pour PU foam material, and close the mold to form.

Embodiment 2

[0031] After cleaning the 6mm thick rubber wear-resistant parts, put the glue into the mold, put the 0.2mm thick stretchable film into the mold to cover the bottom of the mold, close the frame film, and then heat the mold at 45°C for 20-40min. Pump the air in the mold for 10-25 seconds, pour the foam material, and close the mold to form.

Embodiment 3

[0033] After cleaning the 10mm thick rubber wear-resistant parts, put the glue into the mold, put the 0.2mm thick TPU thermal adhesive film into the mold to cover the bottom of the mold, close the frame film, and then heat the mold at 55°C for 20-40min. Pump the air in the mold for 10-25 seconds, pour the foam material, and close the mold.

Abstract

The invention discloses a novel manufacturing process for shoe soles, which comprises the steps of: cleaning the wear-resistant accessories; brushing glue on the surface of the wear-resistant accessories to be bonded, and placing the treated wear-resistant accessories with the surfaces to be bonded upwards in a mold ; Place the stretchable film in the mold to cover the wear-resistant parts and the bottom of the mold, fix the stretchable film in the frame closing mold, and heat the mold; vacuumize the inside of the mold to make the stretchable film and the bottom of the mold fit smoothly and tightly, and then Fill the foam material into the mold and close the mold to form it. In the present invention, the wear-resistant sheet and the stretchable film are integrally formed into an integral sole structure when the foam is formed, the process flow is short, the production cycle is short, it can be produced in an assembly line, and the work efficiency is high. The sole made by the present invention is not easy to crack, and the wear-resistant sheet The material and the foaming material are firmly bonded. The sole has no bubbles during the production process, no exposed rubber layer, no bubbles, smooth surface, beautiful appearance, uniform color, stable product properties, and easy to control.

Description

【Technical field】 [0001] The invention relates to a novel shoe sole manufacturing process, which belongs to the technical field of shoe sole processing. 【Background technique】 [0002] Existing shoe soles generally include a wear-resistant sheet and a foam structure. The traditional manufacturing method of this type of shoe sole is post-lamination combination, that is, the formed wear-resistant sheet is bonded with the stretchable film and the formed foam structure. At the same time, the traditional production method has a large number of workers, is easy to be messy, has a long process, is not fixed in the production cycle, and has low work efficiency. Stable and difficult to control. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the traditional manufacturing method and provide a novel sole manufacturing process of integral molding. The process of the invention has high manufacturing effici...
