Problems solved by technology
When the product has a bad cut, it is necessary to adjust the overall closing height of the equipment, or thicken the sponge pad, which is very inconvenient for debugging and installation, resulting in a waste of time and manpower, and increasing the production cost
In addition, the punching force during punching is not easy to control. Excessive force will easily accelerate the damage of the knife edge, resulting in reduced life of the knife die and frequent tool changes.

The invention discloses a die-cutting die structure which comprises a fixed die, a movable die, a bulb block, a rectangular spring and a set screw. A fixed die edge is mounted on a metal fixed plate, a movable die cushion block is mounted on the movable die, the bulb block is mounted at the back of the movable die cushion block, the rectangular spring is mounted at the back of the bulb block of the movable die, and the set screw is mounted at the back of the rectangular spring of the movable die. The die-cutting die structure is applicable to die-cutting of sheets with different thicknesses, the bulb block mounted at the back of the movable die cushion block is used for balancing the extrusion force of all positions of the edge, moderate die-cutting extrusion force is ensured, product cutting quality is ensured, and the service life of a cutting die is prolonged.
Description
technical field [0001] The invention relates to the field of molds, in particular to a high-life knife mold suitable for punching various sheet thicknesses. Background technique [0002] At present, the knife edge of the fixed mold of the knife mold structure is fixed with a wooden board, and a layer of backing plate is placed on the corresponding movable mold, and a layer of sponge pad is added behind the backing plate to ensure that the backing plate has a certain degree of elasticity. When the product has a bad cut, it is necessary to adjust the overall closing height of the equipment, or thicken the sponge pad, which is very inconvenient for debugging and installation, resulting in a waste of time and manpower, and increases the production cost. Moreover, the punching force during punching is not easy to control. Too much force will easily accelerate the damage of the knife edge, resulting in reduced life of the knife die and frequent tool changes. Contents of the inve...
