Description

Technical Field

[0001] This utility model relates to the field of shoemaking equipment technology, specifically to a combined injection molding shoe pressing device. Background Technology

[0002] Injection-molded shoes are footwear made through an injection molding process. Their soles are typically made of plastic. Injection-molded shoes consist of a sole and an upper, which can be glued together.

[0003] A search revealed that patent application number 202122434859.1 discloses a shoe-making pressing device to prevent shoe soles from sticking together, relating to the field of shoe-making equipment technology: it includes a workbench, the top of which is provided with a shoe sole groove for placing shoe soles, a downward-facing cylinder is mounted on the workbench above the shoe sole groove via a mounting frame, a shoe stretcher for supporting the shoe upper is mounted at the bottom of the cylinder, a washing tank is provided on the top surface of the workbench, and a cleaning mechanism that rotates back and forth between the shoe sole groove and the washing tank is provided between the two.

[0004] Although the shoe-making pressing device for preventing sole adhesion uses an electric push rod to drive the cleaning head to dip into the cleaning solvent in the rinsing tank and rotate it into the sole groove for cleaning, preventing the sole groove from sticking due to adhesive overflow and affecting the removal of the shoes, this shoe-making pressing device for preventing sole adhesion cannot perform the bonding work between the sole and the upper when cleaning the sole groove, resulting in low work efficiency. In addition, the cleaning head cannot move along the inside of the sole groove, and cannot perform a thorough cleaning of the sole groove, resulting in poor cleaning effect.

[0005] Therefore, we propose a combined injection molding device for shoes. Utility Model Content
