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 novel sole making process. The process comprises following steps: cleaning an abrasion resistant attachment; gluing a to-be-bonded surface of an abrasion resistant attachment and upwardly putting the processed to-be-bonded surface of the abrasion resistant attachment to a die; putting a telescopic film to the die to cover abrasion resistant attachment and a sole, wherein a frame-combining die is used for fixing the telescopic film and heating the die; carrying out vacuum processing in the die such that the telescopic film and a film bottom are closely and smoothly attached, and pouring foaming material to the die and finishing die-combining. The novel sole making process has following beneficial effects: abrasion resistant sheet material and the telescopic film are integrated into an overall sole structure when foams form; operation flow is short; a production cycle is short; flow line production is achieved; working efficiency is high; the sole is not easy to crack; the abrasion resistant sheet material and foaming material are firmly bonded; during the process of making the sole, no foams appear and a glue layer is not exposed without foams; the surface is smooth and attractive in external appearance and uniform in color; a physical property of a product is stable and easy control is achieved.

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...
