Description

Technical Field

[0001] The utility model relates to the field of die-cutting machine equipment, in particular to a blanking die convenient for waste cleaning. Background Art

[0002] During the die-cutting process of butyl gaskets, when using a traditional waste cleaning die, manual cleaning of waste materials is required, and the waste materials easily block the blanking groove, resulting in the product not being cut off during die-cutting and the waste materials not being discharged in time, leading to material loss. After the waste materials are blocked, the die needs to be disassembled, cleaned, and then reinstalled and debugged, wasting production time. The utility model patent with the publication number CN201268016Y discloses a bottom waste cleaning engraving die. The device includes an engraving die, two lower cushion dies, four lower cushion die fixing screws, four lower cushion die fixing screw holes, four template fixing screws, and four template fixing screw holes. First, a cutting edge protruding from the engraving die plane is carved on the engraving die, and the part with a small gap between the cutting edges is cut into a tapered through hole. Four lower cushion die fixing screw holes are provided on the outer frame of the engraving die, and four template fixing screw holes are provided outside the four lower cushion die fixing screw holes. The two lower cushion dies are respectively provided with corresponding four lower cushion die fixing screw holes and four template fixing screw holes on their frames. The lower cushion die is fixed below the engraving die through the four lower cushion die fixing screws, and a blanking groove with a certain gap is left in the middle part of the lower cushion die. Although this device can automatically concentrate the waste materials in the waste material groove, it does not realize the function of automatically cleaning the waste material groove and still requires manual cleaning of the waste material groove at regular intervals. This not only has the risk of blocking the waste material groove but also affects production efficiency. How to solve the above problems has become an urgent technical problem to be solved.
