Description

Cutting die Technical Field The utility model relates to the technical field of dies, in particular to a cutting die. Background In the field of precision machining of materials such as metal plates and plastic products, a punching and cutting die is core machining equipment. The traditional cutting die mainly adopts a vertical opposite punching structure, and the upper die punch and the lower die knife edge are directly opposite-pressed to complete cutting. The structure has three remarkable defects that (1) waste is easy to accumulate in a die cavity to cause die clamping and frequent shutdown and cleaning are needed, (2) burrs are easy to occur on the edges of materials generated by vertical cutting, the cost is increased by secondary polishing, and (3) the requirement of cutting with angles cannot be met, so that the application scene is limited. In order to solve the problem of waste discharge, the prior art proposes to add a spring ejector rod structure on the lower die, but the ejector rod is easy to wear and can only realize vertical ejection, and still has residues on viscous materials (such as rubber). In addition, the spiral chip groove design is adopted, but the strength of the cutter head is reduced. In the aspect of inclined plane cutting, step-by-step processing (vertical cutting and bending) is adopted at present, so that the working procedure is complex and the precision is lost. The foregoing background is only for the purpose of providing an understanding of the principles and concepts of the utility model and is not necessarily related to the prior art or is not necessarily taught by the present application and is not intended to be used for the purposes of assessing the novelty and creativity of the present utility model without express evidence that such is already disclosed prior to the filing date of this patent application. Disclosure of utility model In order to solve the technical problems that high-efficiency waste discharge and angular cutting cannot be synchronously realized in single stamping, the utility model provides a cutting die, and the high-efficiency waste discharge and the angular cutting are synchronously realized in single stamping by innovatively designing a cooperative structure of an inclined cutter head and a central waste discharge piece, so that the processing efficiency and the quality of a finished product are remarkably improved.
