The technical realization elements of the long-life engraving round die

Technical realization elements:

4. The purpose of the present utility model is to provide a long-life engraving round knife die to solve the problems raised in the background art.

5. In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a long-life engraving round knife mold, including a cylinder, the inner wall of the cylinder is fixedly connected with a circular plate, and the upper surface of the circular plate is fixed A drive motor is installed, the output end of the drive motor is fixedly connected with a screw rod, the outer surface of the screw rod is threadedly connected with a threaded sleeve, the bottom end of the threaded sleeve is fixedly connected with a lifting plate, the lifting plate A knife mold is fixedly installed on the lower surface of the knife mold, a groove is provided on the inside of the knife mold, an opening is opened on the lower surface of the groove, and a moving block is movably inserted into the lower surface of the groove through the opening. A cutter is fixedly connected to the lower surface of the cylinder, two side walls of the cylinder are provided with sliding grooves, and a bottom plate is fixedly connected between the two sliding grooves.

6. Preferably, a sealing sleeve is fixedly inserted through the outer surface of the circular plate, and the bottom end of the screw rod extends to the inside of the cylinder through the sealing sleeve.

7. Preferably, the lifting plate is arranged in a circular shape, the outer surface of the lifting plate is fixedly connected with a sealing ring, the inner wall of the cylinder is fixedly connected with a sealing ring, and the outer surface of the lifting plate is connected with the sealing ring through the sealing ring. The sealing rings are in close contact.

8. Preferably, a plurality of sleeves are fixedly connected to the lower surface of the circular plate, and a moving rod is movably inserted through the inside of the sleeve, and the moving rod is fixedly connected to the lifting plate.

9. Preferably, an air pipe is communicated with the upper surface of the knife mold and the circular plate, and a one-way valve is provided inside the air pipe.

10. Preferably, a pull-back spring is fixedly connected between the groove and the moving block.

11. Preferably, the bottom walls of the two sliding grooves are fixedly connected with a buffer block, and the buffer block is made of high-quality rubber material, and the buffer block is fixedly connected to the bottom plate.

12. Preferably, a plurality of bases are fixedly connected to the lower surface of the cylinder, a hinge base is fixedly connected to the opposite side of the base and the bottom plate, and a telescopic rod is hinged between the two symmetric hinge bases, A buffer spring is sheathed on the outer surface of the telescopic rod.

13. Compared with the prior art, the beneficial effects of this utility model are:

14.1. The utility model has a simple structure. By adjusting the pressure inside the cylinder, the cutter can automatically move down after the stamping is completed, so that the residual material under the cutter die can automatically fall down, reducing the later product scrap Rate;

15.2. The utility model uses the buffer block and the buffer spring to gradually weaken the pressure, which can greatly protect the knife mold, prevent the cutter under the knife mold from being damaged, and thereby prolong the service life of the knife mold.
