Technical Field

[0001] The utility model relates to the technical field of presses, in particular to a quick die-loading mechanism for a trimming press. Background Art

[0002] The working principle of the press is to use die cutting knives, steel knives, hardware molds, steel wires, and apply a certain pressure through the stamping plate to roll and cut the blank into a certain shape. The mold is used in industrial production for injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods to obtain various molds and tools for the required products. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. The mold is an important component of the press.
