Abstract
The utility model discloses a hemming device of a thermoforming machine, which comprises an upper die and a lower die, the upper die and the lower die are arranged in a mutually vertical lifting manner, a transferring device transversely penetrates through a plastic box is arranged between the upper die and the lower die, a plurality of forming angle pressing strips are arranged on the lower surface of the upper die, and a heating device is arranged in the upper die. The heating device heats the forming angle pressing strips, a mold table is arranged on the lower mold, a plurality of pressing grooves are formed in the mold table, chamfering convex edges are arranged on the inner walls of the peripheries of the pressing grooves, the forming angle pressing strips and the chamfering convex edges ascend and descend to clamp burrs of a plastic box and extrude the edge of a product so that the product can be chamfered and formed, and ejection assemblies are arranged at the bottoms of the grooves. The forming angle pressing strip in the mold is used for forming the side edge of a product, the side edge of the product is formed into a curled edge through the forming structure, and the phenomenon that a hand is scratched by convex points and burrs of a side plate is avoided; a hot runner is arranged in the upper die and heats a forming angle pressing strip of the upper die, forming is convenient, and the hemming efficiency is improved.
