Description

Technical Field

[0001] The utility model relates to the technical field of shoe-making machines, in particular to a hot mold mechanism of a toe shaping machine. Background Art

[0002] In the shoemaking process, shaping the toe area is one of the most critical steps, directly impacting the aesthetics of the shoe. A common shoe shaping machine is used in this process. These machines primarily include cold and hot molds. The hot mold heats the shoe material, while the cold mold presses down to shape it.

[0003] The hot mold mechanism mainly includes a cylinder and an upper mold and a lower mold arranged above and below. The cylinder is usually arranged above the upper mold to drive the upper mold to close and open the mold. However, since the applicant adjusted the positions of the cold mold mechanism and the hot mold mechanism, changing them to a front-to-back adjacent manner, the staff can directly place the shoe materials from the hot mold mechanism on the material level of the cold mold mechanism without moving. However, since the cylinder is arranged above the upper mold, it occupies the space above the upper mold, reducing the range of movement of the staff's arms above the upper mold, hindering the staff's work process of placing the heated shoe materials on the material level of the cold mold mechanism, affecting production efficiency. Therefore, the applicant believes that improvements should be made to the relevant structures to avoid the above-mentioned obstruction problems. Utility Model Content
