AI Technical Summary

Problems solved by technology

Due to the different materials of the upper and sole adhesive surfaces, the types and properties of the adhesives used are also different, such as neoprene adhesives, polyurethane adhesives, SBS adhesives, etc., which will cause pollution problems when using glue bonding, such as The glue has a strong smell, harmful substances will cause harm to the workers and wearers, and it is not conducive to environmental protection
The seam connection process is quite time-consuming and laborious, and wastes resources
In addition, for shoes connected by the above method, the upper and the sole will be separated from each other after a period of use, such as degumming, etc.

Embodiment 1

[0031] The production process of integrated shoes:

[0032] First, open the mold, spray the release agent, dry the release agent, and control the mold temperature at 55°C, then put the wear-resistant negative film RB / TPU into the mold, cover the middle mold, place the TPU hot-melt film, and check the TPU hot-melt film Whether it is placed properly; again, turn on the vacuuming machine, adjust the position of the hot-melt film, hang it on the mold, and heat the hot-melt film to 35°C; again, place the upper with the last, close the middle frame and clamp the mold , filled with PU material; finally, combined with the upper mold containing the upper of the last, and molded for 7 minutes to open the mold and take out the finished shoe.

Embodiment 2

[0034] The production process of integrated shoes:

[0035] First, open the mold, spray the release agent, dry the release agent, and control the mold temperature at 60°C, then put the wear-resistant negative film RB / TPU into the mold, cover the middle mold, place the TPU hot-melt film, and check the TPU hot-melt film Whether it is placed properly; again, turn on the vacuuming machine, adjust the position of the hot-melt film, hang it on the mold, and heat the hot-melt film to 35°C; again, place the upper with the last, close the middle frame and clamp the mold , filled with PU material; finally, combined with the upper mold containing the upper of the last, and molded for 7 minutes to open the mold and take out the finished shoe.

Embodiment 3

[0037] The production process of integrated shoes:

[0038] First, open the mold, spray the release agent, dry the release agent, and control the mold temperature at 60°C, then put the wear-resistant negative film RB / TPU into the mold, cover the middle mold, place the TPU hot-melt film, and check the TPU hot-melt film Whether it is placed properly; again, turn on the vacuuming machine, adjust the position of the hot-melt film, hang it on the mold, and heat the hot-melt film to 40°C; again, place the upper with the last, close the middle frame and clamp the mold , filled with PU material; finally, combined with the upper mold containing the upper of the last, and molded for 6 minutes to open the mold and take out the finished shoe.

Abstract

The invention belongs to the field of shoe manufacturing, and in particular, relates to a manufacturing process of integrally molded shoes. The manufacturing process of the integrally molded shoes issimple in process, rigid and durable. The manufacturing process of the integrally molded shoes comprises treatment of wear resisting pieces (RB / TPU), TPU protective films, vamps containing shoe treesfor molding uppers, and PU raw materials; and the process comprises the following specific steps: firstly, mold opening is performed; a demolding agent is sprayed, and is dried by blowing; the mold temperature is controlled within 55-60 DEG C; secondly, wear resisting bottom pieces RB / PTU are put in molds and cover middle molds; TPU hot melting films are placed; and placement of the PTU hot melting films is checked; then, a vacuumizing machine is started; for the vacuumizing effect, the positions of the hot melting films are adjusted; the hot melting films are hung on the molds, and are heatedto 35-40 DEG C; then, the vamps containing the shoe trees are placed; middle frame clamping molds are closed; and PU materials are filled; and finally, upper molds of the vamps containing the shoe trees are molded by 6-7 minutes, and are opened to take out finished shoes.

Description

technical field [0001] The invention belongs to the field of shoe manufacturing, and in particular relates to a manufacturing process of integrally formed shoes. Background technique [0002] In existing shoes, especially casual shoes, the upper and the sole are generally connected by a specific method (such as glue, sewing or other methods). Among them, adhesive shoes are made by sticking the outsole to the upper, which needs to be completed by bonding the outsole and the upper. Adhesive shoes process is also called cold bonding process, which is a process method that uses adhesives to connect the upper, inner sole and outer sole together. Due to the different materials of the upper and sole adhesive surfaces, the types and properties of the adhesives used are also different, such as neoprene adhesives, polyurethane adhesives, SBS adhesives, etc., which will cause pollution problems when using glue bonding, such as The glue has a strong smell, and harmful substances will ...
