The motor 504 is fixedly connected to the top of the placement frame 503, and its output end is fixedly connected to the double-ended screw 502. The two movable blocks 505 are threadedly connected to the two sides of the surface of the double-ended screw 502. The two bases 506 are respectively fixedly connected to the top of the two movable blocks 505.

[0025] Specifically, the movable structure 5 can be used to flexibly adjust the size of the mold, thereby clamping the mold through the clamping and positioning structure 6.

[0026] Furthermore, once the mold is placed on the placement platform 3, the motor 504 can be started. The motor 504 can drive the double-headed screw 502 to rotate. When the double-headed screw 502 rotates, it can drive the two threaded moving blocks 505 to move. Then, the base platform 506 can be moved by the movement of the moving blocks 505.

[0027] Example 3 In the third embodiment of the present invention, the clamping and positioning structure 6 includes an electric cylinder 601, two through holes 602, a connecting plate 603, a push rod 604, and two guide rods 605.

The connecting plate 603 is fixedly connected to the output end of the electric cylinder 601. The push rod 604 is snapped into the bottom of the connecting plate 603. The two guide rods 605 are snapped into the surface of the push rod 604 and extend through and out of the through holes 602. A contact pad 7 is fixedly connected to one side of the guide rod 605 extending through and out of the base 506. A locking block 8 is fixedly connected to the bottom of the connecting plate 603.

The connecting seat 14 is slidably connected to the sliding grooves 4 on the front and rear sides. A frustum 15 is rotatably connected to the bottom of the connecting seat 14, and the frustum 15 is also slidably connected to the sliding grooves 4 on the front and rear sides.

[0028] Specifically, the clamping and positioning structure 6 can be activated to clamp the placed mold, thereby improving the stability of the mold during stamping and preventing it from moving.

[0029] Furthermore, once the base 506 has moved to the appropriate position, the electric cylinder 601 can be activated. The electric cylinder 601 can drive the connecting plate 603 to move. After the connecting plate 603 moves, it can drive the push rod 604 to move. After the push rod 604 moves, it can drive the guide rod 605 to move. After the guide rod 605 moves, it can drive the contact pad 7 to move, thereby making contact with the mold surface through the contact pad 7, thus improving the stability of the mold on the placement platform 3.

[0030] refer to Figures 1 to 6 The usage method includes the following steps: Step 1: Place the horn mesh mold to be stamped on top of the placement table 3; Step 2: Then, the moving structure 5 can be activated according to the size of the mold, and the clamping and positioning structure 6 can be moved by the moving structure 5. Step 3: Once the clamping and positioning structure 6 has moved to the appropriate position, it can be started to improve the stability of the mold on the placement table 3 by clamping it. Step 4: The die can be stamped using the stamping machine body 2.

[0031] Working principle of the invention: After the mold is placed on the placement platform 3, the motor 504 can be started. The motor 504 can drive the double-headed screw 502 to rotate. After the double-headed screw 502 rotates, it can drive the two threaded moving blocks 505 to move. Then, the movement of the moving blocks 505 can drive the base 506 to move. After the base 506 moves to the appropriate position, the electric cylinder 601 can be started. The electric cylinder 601 can drive the connecting plate 603 to move. After the connecting plate 603 moves, it can drive the push rod 604 to move. After the push rod 604 moves, it can drive the smooth rod 605 to move. After the smooth rod 605 moves, it can drive the contact pad 7 to move. In this way, the contact pad 7 contacts the mold surface, thereby improving the stability of the mold on the placement platform 3.
