[0035] The upper die 2 lower part is fixedly connected with a male die 23, and the upper die 2 front and back surfaces are respectively provided with guiding sliding grooves 21;

[0036] The upper die base 3 is slidingly connected with the upper die 2, and the upper die base 3 is respectively provided with slot holes 31 on both sides, and the slot holes 31 are fixedly connected with guiding sliding grooves 311 on the inner walls away from the upper die 2, and the guiding sliding grooves 311 are slidingly connected with telescopic strips 51, and the telescopic strips 51 are provided with strip-shaped teeth 511;

[0037] The baffle assembly comprises a fixed block 22, a fixed block 32, a connecting rod 221, a connecting rod 321, and a baffle 4.

[0038] One end of the fixed block 22 is fixedly connected to the surface of the upper die 2, one end of the fixed block 32 is fixedly connected to the upper die base 3, one end of the connecting rod 221 is movably connected with the fixed block 22, the other end is movably connected with the connecting rod 321, one end of the connecting rod 321 is movably connected with the fixed block 32, and the baffle 4 is movably connected to the lower part of the connecting rod 321.

[0039] The pressing assembly comprises telescopic strips 51, a gear 52, and a strip-shaped plate 53.

[0040] The strip-shaped plate 53 is fixedly connected to the opposite sides of the upper die 2, the strip-shaped plate 53 is provided with strip-shaped teeth 531 at the lower end, the gear 52 is in the gap between the telescopic strips 51 and the strip-shaped plate 53 and is respectively engaged with the strip-shaped teeth 511 and the strip-shaped teeth 531, the gear 52 is movably connected to a rotating shaft 521, and both ends of the rotating shaft 521 are fixedly connected to the inner walls of the slot holes 31; the pressing assembly is formed by rotating and cooperating, so that the lower end of the telescopic strip 512 can reach the lowest position of the watering can 14 after the telescopic strip 512 is pressed by the upper die 2.

[0041] When the punch dies are not working, the two sets of shielding plates 4 form a clamping structure, blocking between the punch 23 and the die 13. When the upper die base 3 moves up and down, the connecting rod one 221 in the baffle assembly rotates around the fixed block one 22, driving the connecting rod two 321 to rotate around the fixed block two 32, and then the shielding plate 4 moves away from the punch 23. When the punch 23 moves to the lowest end, the projection of the shielding plate 4 in the vertical direction is in the groove 11, and at the same time, the upper die base 3 drives the strip-shaped plate 53 to move downward, and the gear engaged with it drives the telescopic plate to move upward, and the watering can is in a non-working state.

[0042] In the working state of the mold, the shielding plate limits the movement of the person, so that the working area during the punching is in a state that cannot be approached, thereby protecting the personal safety of the worker. The shielding plate is in front of the worker, blocking the flying debris generated during the stamping process from hitting the worker. At the same time, the debris is blocked by the shielding plate and falls into the groove under the action of gravity, facilitating cleaning and cleaning after each punching work. The upper die automatically presses the watering can to spray lubricating oil to lubricate the mold, reducing wear and deformation, protecting the stamping mold, reducing the mold failure rate, and improving the lubricating efficiency. When the mold does not need to be lubricated, the idle placing groove can be used, and the operation is convenient.

When the debris splashes, it is better to block it in the groove 11, so as not to hit the side of the shielding plate away from the punch, providing better protection for the worker.

[0044] Preferably, when the upper end of the upper die 2 reaches the highest position, the projection of the shielding plate 4 in the vertical direction is close to the center position of the die 13, ensuring that the worker cannot directly contact between the punch 23 and the die 13 during demolding, better protecting the worker's hands and reducing injury.

[0045] Preferably, the upper surface of the die 13 is lower than the upper surface of the lower die 1, which better blocks the debris in the groove 11 when it splashes.

[0046] Preferably, the top of the spray pot 14 is higher than the upper surface of the concave die 13 after the spray pot 14 is placed in the placing groove 12, so that the lubricating liquid in the spray pot can better cover the surface of the concave die when sprayed.

[0047] Preferably, the pressing head 512 at the bottom of the telescopic strip 51 is made of rubber, and the projection of the pressing head in the vertical direction is greater than the projection of the spray pot 14 in the vertical direction, so that the spray head can be pressed more accurately and effectively.

[0048] Preferably, the shielding plate 4 has two groups and is in a fine mesh structure, so that when the worker faces the die, the front is protected by the shielding plate and the shielding plate is transparent, and the working process of the die can be observed at any time.

[0049] In summary, according to the above technical scheme of the utility model, when the stamping die is not working, the two groups of shielding plates 4 form a clamping structure and block between the convex die 23 and the concave die 13, when the stamping die moves downward, the connecting rod one 221 in the baffle assembly makes circular motion around the fixed block one 22, drives the connecting rod two 321 to make circular motion around the fixed block two 32, and then the shielding plate 4 moves away from the convex die 23, at this time, the shielding plate 4 blocks the approach of the personnel and shields the flying of the scraps in the pressing process, and the shielding plate 4 falls into the groove 11 under the action of gravity, so that the worker can clean up conveniently, when the convex die 23 moves to the lowest end, the projection of the shielding plate 4 in the vertical direction is in the groove 11, and the upper die base 3 drives the strip-shaped plate 53 to move downward, the gear engaged with the strip-shaped plate 53 drives the telescopic plate to move upward, and the spray pot is in a non-working state, when the stamping die moves upward after completing the stamping, the connecting rod one 221 in the baffle assembly drives the connecting rod two 321 and then the shielding plate 4 moves towards the convex die 23, and blocks between the convex die 23 and the concave die 13, at this time, the worker performs the demolding operation, at this time, the upper die base 3 drives the strip-shaped plate 53 to move upward, the gear engaged with the strip-shaped plate 53 drives the telescopic plate to move downward, so that the pressing head 512 reaches the lowest position to press the spray pot 14, and then the lubricating oil in the spray pot 14 is sprayed on the upper surface of the concave die 13 to play a lubricating role, during the working process of the die, since the shielding plate 4 is made of transparent material, the worker can observe the working state of the die at any time, and monitor the accuracy and safety of the working process of the die.
