Description

Technical Field

[0001] The utility model relates to the technical field of shoemaking, in particular to a fast-detachable cold mold shaping device for a toe shaping machine and the toe shaping machine. Background Art

[0002] As people's living standards continue to improve, people's pursuit of wearing shoes is becoming more and more fashionable. In order to meet market demand, shoe manufacturers have designed a variety of shoe types with different shapes. However, in the process of shoemaking, whether it is men's shoes, women's shoes, pointed shoes, square shoes or round shoes: the toe of the shoe still needs to be completed by the toe shaping machine. During operation, the leather or cloth of the shoe needs to be loaded onto the inner support table, and then the outer support table is driven to move relative to one side of the inner support table. First, the outer support table is allowed to rest against the middle plate fixture to clamp the cloth, and then continue to move toward the inner support table, so that the cloth is tightened on the inner support table and the shaping operation of the front of the shoe is completed. Subsequently, the front of the shoe that has been shaped is bonded to the sole.

[0003] The inventor discovered during actual production operations that the inner support platform devices used in existing toe molding machines are all fixed by screw fastening. Once an inner support platform of a different specification needs to be replaced, the screws need to be loosened and tightened, and then the inner support platform is removed from the toe molding machine and replaced with an inner support platform of other specifications. After the position of the inner support platform is debugged, it is fixed to the toe molding machine with screws. This replacement method is time-consuming and labor-intensive, and disassembly, assembly and debugging are very inconvenient.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content
