[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] Please refer to the following: Figure 1-4 A multi-die stamping mechanism with quick die changing includes a worktable 1. A groove 2 is provided on the upper surface of the worktable 1. A positioning post 3 is movably fitted to the inner wall of the groove 2. A lower die 4 is fixedly installed on the upper surface of the positioning post 3. A first side plate 5 is fixedly installed on the outer surface of the lower die 4. A fixing post 6 is movably installed in the middle of the first side plate 5. A second side plate 7 is movably installed on the outer surface of the fixing post 6. An upper die 8 is fixedly installed on the inner wall of the second side plate 7. Baffles 9 are fixedly installed on both the upper and lower surfaces of the fixing post 6. An installation plate 10 is fixedly installed on the upper surface of the worktable 1. A telescopic rod 11 is fixedly installed on the lower surface of the installation plate 10. An installation frame 12 is fixedly installed at the lower end of the telescopic rod 11. An installation groove 13 is provided on the lower surface of the installation frame 12. A positive and negative lead screw 14 is movably installed on the inner wall of the installation groove 13. A servo motor 15 is fixedly installed on the right surface of the installation frame 12. A limit block 16 is hinged to the outer surface of the positive and negative lead screw 14. A limit frame 17 is fixedly installed on the upper surface of the upper die 8.

[0022] Specifically: When the mold needs to be replaced during the use of this utility model, the servo motor 15 is started first, which drives the positive and negative lead screws 14 to rotate. The rotation of the positive and negative lead screws 14 drives the limiting block 16 to move away from each other. When the limiting block 16 moves, it gradually moves away from the inner wall of the limiting frame 17. When the limiting block 16 is completely away from the inner wall of the limiting frame 17, the telescopic rod 11 retracts, which drives the mounting frame 12 to move upward as a whole. After the movement is completed, the upper mold 8 and the lower mold 4 can be taken out upward as a whole. When it is necessary to install them, the positioning pin 3 is placed inside the groove 2, and the principle is reversed to install the upper mold 8 and the lower mold 4 as a whole.

[0023] In this implementation scheme: a controller 21 is fixedly installed on the front surface of the workbench 1.

[0024] Specifically: the device is started and closed via controller 21.

[0025] In this implementation scheme: the output end of the servo motor 15 is fixedly connected to the right end of the positive and negative lead screw 14, and the outer surface of the limiting block 16 is movably connected to the inner wall of the mounting groove 13.

[0026] Specifically: the servo motor 15 drives the forward and reverse lead screws 14 to rotate, thereby causing the limit block 16 to move.

[0027] In this implementation scheme: the controller 21 is electrically connected to the servo motor 15 and the telescopic rod 11.

[0028] Working principle: This utility model uses a servo motor 15 to drive the forward and reverse lead screws 14 to rotate, thereby moving the limit block 16 to limit and install the upper mold 8 and the lower mold 4 as a whole. The telescopic rod 11 drives the mounting frame 12 to move as a whole. Compared with related technologies, the multi-mold stamping mechanism with quick mold changing provided by this utility model has the following beneficial effects: This design can achieve the effect of convenient disassembly and installation of the upper mold 8 and the lower mold 4 as a whole. The replacement is simple, and the upper mold 8 and the lower mold 4 can be disassembled and installed at the same time, which improves efficiency.

[0029] Example 2:

[0030] Please refer to the following: Figure 1-4 A sleeve 18 is fixedly installed on the front surface of the lower mold 4, a column 19 is movably installed on the inner wall of the sleeve 18, and a spring 20 is fixedly installed on the lower surface of the column 19.

[0031] Specifically: In the process of using this utility model, when the mold is stamped after installation, the telescopic rod 11 extends, thereby pushing the mounting frame 12 and the upper mold 8 to move downward. When the upper mold 8 moves downward, the sleeve 18 moves downward toward the inside of the column 19, thereby compressing the spring 20. The compressed spring 20 rebounds against the column 19, thereby rebounding against the upper mold 8, thus achieving the effect of buffering the upper mold 8.

[0032] In this embodiment: the lower end of the spring 20 is fixedly connected to the lower inner wall of the sleeve 18, and the rear surface of the tube column 19 is fixedly connected to the front surface of the upper mold 8.

[0033] Specifically: When installing and disassembling the upper mold 8 and the lower mold 4, the pipe column 19 and the pipe sleeve 18 are also installed and disassembled in the same way.

[0034] Working principle: This utility model uses the downward movement of the tube column 19 to compress the spring 20. The compressed spring 20, under the action of elasticity, pushes the tube column 19 upward, thereby buffering the upper mold 8. Compared with related technologies, the multi-mold stamping mechanism with quick mold changing provided by this utility model has the following beneficial effects: This design can achieve the effect of buffering the contact between the upper mold 8 and the lower mold 4, thereby avoiding the situation where the mold is damaged due to excessive contact and collision force, thus avoiding unnecessary economic losses.

[0035] The controller 21 is an existing structure, and the control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the field. It is only used and not modified. Therefore, the control method and circuit connection will not be described in detail.

[0036] The selection of various devices varies depending on the specific circumstances, and should be based on the actual needs and various parameters, taking into account the function and desired effect of the equipment.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
