Injection molding insole, method for manufacturing injection molding insole and injection mold of injection molding insole

Abstract

The invention discloses an injection molding insole. The injection molding insole comprises a front sole part and a heel part; the insole further comprises an upper surface layer and a lower surface layer; the upper surface layer and lower surface layer of the heel part are separated from each other; at least one part of the upper surface layer and one part of the lower surface layer of the front sole part are mutually bonded; and a plastic layer is arranged between the upper surface layer and the lower surface layer in an injection molding manner. The invention further provides a method for manufacturing the injection molding insole and an injection mold of the injection molding insole. According to the injection molding insole disclosed by the invention, a procedure of brushing glue to bond a paperboard layer is saved so that the manufacturing process of the whole insole is simple, rapid and convenient; the standardization of the mold and the standardization of a manufacturing process can be realized; particularly, the setting position of a steel hook center is fixed and unified; the influence on the quality of the insole by manual operation is reduced to the greatest extent so that the specification of the molded insole is uniform and the quality of the molded insole is stable; a worker can easily grasp an operation method and the requirements on the worker is reduced; and more importantly, the pollution is reduced and the body damages on the worker are avoided.

Description

Technical field: [0001] The invention relates to an injection molding midsole. The present invention also relates to an injection mold for the above-mentioned injection midsole. The invention also relates to a method of manufacturing an injection molded midsole. Background technique: [0002] The traditional midsole generally includes an upper surface layer, a plastic layer and a lower surface layer. The plastic layer is provided with a steel hook core. The upper surface layer and the lower surface layer are separate sheets, which need to be glued to the plastic layer manually, so it is expensive It is labor-intensive, inefficient, and the specifications are not uniform, so the quality cannot be guaranteed. What is more serious is that the glue used for gluing is often highly toxic, which is extremely harmful to the human body and easily pollutes the environment. In addition, the setting of the steel shank in the plastic layer is often not accurate enough, resulting in a d...

[0002] The traditional midsole generally includes an upper surface layer, a plastic layer and a lower surface layer. The plastic layer is provided with a steel hook core. The upper surface layer and the lower surface layer are separate sheets, which need to be glued to the plastic layer manually, so it is expensive More labor, low efficiency, and inconsistent specifications, the quality cannot be guaranteed, more seriously, the glue used for gluing is often highly toxic, which is extremely harmful to the human body and easily pollutes the environment

In addition, the setting of the steel shank in the plastic layer is often not accurate enough, resulting in a decrease in the quality of the midsole
