Description

Technical Field

[0001] The present application relates to the technical field of stamping die, and more specifically, to an oblique waste die for processing sealing gaskets. Background Art

[0002] With the development of today's industrial society, various shapes of gaskets are used in all walks of life. For some thin and soft gaskets with a hole diameter less than ￠7mm, a more economical solution is to use a knife die for stamping. However, ordinary knife dies need to be manually cleaned with a pin after stamping, which is time-consuming. In addition, ordinary rear-discharge waste knife dies are used. Due to the small hole diameter, it is easy to block or burst the hole diameter, and shrinkage cavity phenomenon will be caused, resulting in a high product defective rate. If hardware molds are used for stamping, the mold fee is high and the comprehensive material operation efficiency is low. Utility Model Content

[0003] In order to solve the above problems, the present application provides an oblique waste cutter die for gasket processing.

[0007] The above technical solution facilitates the guidance of waste materials inside the cutter head to the waste discharge inclined hole.

[0008] Furthermore, a limit slot is provided on the top of the oblique hole cutter head, and a limit protrusion matching the limit slot is provided on the inner top of each punching slot.

[0009] The above technical solution can effectively prevent the inclined hole cutter head from rotating in the punching slot.

[0010] Furthermore, the waste discharge inclined holes are all triangular bevel cuts, and the bevel cutting depth is not greater than the radius of the inclined hole cutter head.

[0011] Through the above technical solution, waste can be discharged smoothly from the waste discharge inclined hole while ensuring the necessary structural strength of the inclined hole cutter head.

[0012] Furthermore, the top of the waste discharge channel is a slope.

[0013] The above technical solution facilitates waste discharge.

[0014] Furthermore, a plurality of punching slots may share the same waste discharge slot and waste storage cavity.

[0015] The above technical solution can reduce the number of slots on the base plate and the bottom plate, saving production costs.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] (1) This application provides a punching slot and an inclined hole cutter head at the tiny punching hole of the product. The waste discharge inclined hole on the side of the inclined hole cutter head is connected to the waste discharge slot and the waste storage cavity, thereby reducing the storage volume of waste in the cutter head, further shortening the waste discharge path, and avoiding the problem of hole explosion or inability to discharge waste due to the increasing waste discharge pressure in the aperture cavity;
