[0023] As Figures 1-4 shown, the stamping die provided in this embodiment that can prevent the sticking material from returning includes the upper support base 1 and the lower support base 2. The lower surface of the upper support base 1 is installed with the upper stamping die 3, and the upper surface of the lower support base 2 is installed with the lower stamping die 4. The lower surface of the upper support base 1 is provided with an automatic peeling structure 5 around the periphery of the upper stamping die 3. The automatic peeling structure 5 includes two electric telescopic rods 6, a jet-assisted demolding pipe 7 arranged between the two electric telescopic rods 6, and a peeling block 8 arranged at the telescopic end of the electric telescopic rod 6. The upper surface of the upper support base 1 is provided with a compressed air storage tank 9. The upper support base 1 and the lower support base 2 are fixedly connected by a hydraulic rod 20. The upper support base 1 is convenient for supporting and fixing the upper stamping die 3 and the compressed air storage tank 9, and the lower support base 2 is convenient for supporting and fixing the lower stamping die 4 and the hydraulic rod 20. The upper stamping die 3 and the lower stamping die 4 can be tightly clamped together to stamp the stamping raw material plate into a specified shape. The automatic peeling structure 5 is convenient for automatically peeling the stamping finished product clamped on the upper stamping die 3 after stamping. The two electric telescopic rods 6 are convenient for fixedly connecting the peeling block 8 and controlling the sliding of the peeling block 8 through their own telescoping, so as to peel the stamping finished product clamped on the upper stamping die 3. The jet-assisted demolding pipe 7 is convenient for jetting air at the gap when the peeling block 8 peels the stamping finished product, so as to better make the stamping finished product clamped on the upper stamping die 3 fall off quickly and prevent the stamping finished product from deforming during peeling. The peeling block 8 is convenient for peeling the stamping finished product clamped on the upper stamping die 3. The compressed air storage tank 9 is convenient for storing compressed gas. The hydraulic rod 20 is convenient for connecting the upper support base 1 and the lower support base 2, and at the same time is convenient for making the upper stamping die 3 and the lower stamping die 4 clamp or move away from each other through its own telescoping.

[0024] Furthermore, as Figure 2 with Figure 3As shown, the jet-assisted demolding tube 7 includes a metal tube 10, an electrically controlled valve 11 connected to the lower port of the metal tube 10, a connecting tube 12 connected to the lower part of the electrically controlled valve 11, and a flat nozzle 13 connected to the lower port of the connecting tube 12. The metal tube 10 facilitates the support and fixation of the jet-assisted demolding tube 7, and at the same time connects and fixes the electrically controlled valve 11. The electrically controlled valve 11 can cut off the compressed gas entering the connecting tube 12 and the flat nozzle 13 or control the input amount of the compressed gas entering the connecting tube 12 and the flat nozzle 13. The connecting tube 12 facilitates the fixed connection of the flat nozzle 13 to the connecting tube 12. The flat nozzle 13 facilitates spraying the compressed gas into the gap between the stamping upper die 3 and the stamping finished product, facilitating the peeling of the stamping finished product stuck on the stamping upper die 3.

[0025] Further, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the end of the electric telescopic rod 6 is fixedly connected to the lower surface of the upper support base 1 to prevent the electric telescopic rod 6 from shaking. The metal tube 10 passes through the upper support base 1 and is connected to the compressed gas storage tank 9, facilitating the flow of the gas in the compressed gas storage tank 9 into the jet-assisted demolding tube 7.

[0026] Further, as Figure 3 and Figure 4 shown, a first connection and fixing block 14 is provided on the upper surface of the lower support base 2. The stamping lower die 4 is fixedly connected to the upper surface of the first connection and fixing block 14 by bolts, facilitating the replacement of different stamping lower dies 4. The first connection and fixing block 14 facilitates the fixed connection of the stamping lower die 4.

[0027] Further, as Figure 3 and Figure 4 shown, a second connection and fixing block 15 is provided on the lower surface of the upper support base 1. The stamping upper die 3 is fixedly connected to the lower surface of the second connection and fixing block 15 by bolts, facilitating the replacement of different stamping upper dies 3. The second connection and fixing block 15 facilitates the fixed connection of the stamping upper die 3.

[0028] Further, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the stamping upper die 3 and the stamping lower die 4 are mutually engaged and matched, facilitating the stamping upper die 3 and the stamping lower die 4 to be engaged together and perform fitting stamping on the stamping raw material. A sliding slot 16 adapted to the peeling block 8 is penetrated and opened at the four peripheral edges of the lower surface of the stamping upper die 3. The sliding slot 16 facilitates the up and down sliding of the peeling block 8.

[0029] Further, as Figure 3 and Figure 4As shown, a storage groove 17 adapted to the automatic peeling structure 5 is formed on the outer wall around the second connection and fixing block 15. The storage groove 17 facilitates the storage of the automatic peeling structure 5.

[0030] Furthermore, as Figure 1 shown, support legs 18 are provided at the end corners of the lower surface of the lower support base 2. Anti-slip grooves 19 are formed on the lower bottom surface of the support legs 18. The support legs 18 facilitate the support of the device, and the anti-slip grooves 19 can prevent the device from sliding at a slippery working site.

[0031] As Figures 1-4 shown, the principle of the stamping die that can prevent the return of sticky materials provided in this embodiment is as follows: When the device is in use, the appropriate upper stamping die 3 and lower stamping die 4 should be selected according to requirements first, and then the upper stamping die 3 is fixed on the second connection and fixing block 15 through bolts. After that, the lower stamping die 4 is fixed on the first connection and fixing block 14 through bolts. At this time, the electric control valve 11 is in the closed state, and then the electric telescopic rod 6 is in the extended state. At the same time, it is necessary to ensure that the lower surface of the peeling block 8 is on the same plane as the lower surface of the upper stamping die 3.

[0032] At this time, the stamping raw material can be placed in the lower stamping die 4, and then the hydraulic rod 20 will contract to make the upper stamping die 3 move downward until the upper stamping die 3 is engaged with the lower stamping die 4. At the same time, when the upper stamping die 3 is slowly pressed down, the stamping raw material placed on the lower stamping die 4 will be stamped.

[0033] When the upper stamping die 3 finishes stamping the stamping raw material, the hydraulic rod 20 will extend, which makes the upper stamping die 3 engaged with the lower stamping die 4 move upward. At this time, the stamping finished product may be engaged with the upper stamping die 3, and then the electric telescopic rod 6 will extend rapidly, so that the peeling block 8 at the end of the electric telescopic rod 6 will push the edge of the stamping finished product for peeling. At the same time, when there is a gap between the edge of the stamping finished product and the upper stamping die 3, the electric control valve 11 will open rapidly, and then the compressed gas will flow out of the compressed gas storage tank 9 quickly, flow along the metal pipe 10, through the connecting pipe 12 and be sprayed out from the flat nozzle 13. At this time, the sprayed compressed air flow will quickly fill the gap between the edge of the stamping finished product and the upper stamping die 3, and the inflation and extrusion will make the gap larger, which will quickly peel off the stamping finished product engaged with the upper stamping die 3, and at the same time, it will not cause deformation damage to the stamping finished product during peeling. At this time, the electric telescopic rod returns to the initial position, the electric control valve 11 will close rapidly, and then the operator can take out the stamping finished product, and then the next stamping of the stamping raw material can be carried out.
