The lifting height of the rotating block 14 is less than the sliding distance of the limit rod 12 in the embedding groove 13. The bonding block 16 forms a lifting structure with the inside of the punching table 1 through the winding groove 17, and the top of the knocking rod 15 is set with elastic rubber.

[0026] First, when it is convenient to demould the material adhered to the inside of the punching table 1, the connecting sleeve 7 threadedly connected to the top outer side of the rotating screw 6 is moved by rotating the rotating screw 6, so that the connecting sleeve 7 can drive the moving frame 8 to move its position inside the punching table 1, and then the moving frame 8 can slide inside the punching table 1 through the guide rod 9. At this time, the movement of the moving frame 8 can adjust the movement of the position of the driving motor 10, so that the fan blade 11 fixed to the output end of the driving motor 10 can drive the limiting rod 12 to be embedded in the embedding groove 13. The rotation of the limiting rod 12 makes the rotating block 14 drive the knocking rod 15 and the bonding block 16 to rotate, and then the bonding block 16 can be set through the winding groove 17, so that the rotating block 14 can move back and forth on the outside of the limiting rod 12, and then the knocking rod 15 can knock and vibrate the inside of the punching table 1, and overcome the adhesion between the molded part and the punch 3 by vibration, which is convenient for subsequent demoulding.

[0028] When the molded parts are cooled, the head first transports coolant to the inside of the water pipe 5, and the coolant enters through one end of the water pipe 5. The coolant is arranged in a winding manner inside the stamping table 1, and the internal molded parts of the punch 3 and the die 4 are initially cooled by the coolant. The drive motor 10 can be started so that the output end of the drive motor 10 drives the fan blades 11 to rotate, and it is necessary to ensure that the top position of the limit rod 12 is below the rotating block 14. The fan blades 11 are rotated for air cooling again. The wind force of the fan blades 11 is combined with the coolant transported by the water pipe 5 to achieve a more efficient cooling process.
