DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides a technical solution, a die holder locking device for a hot forging press. Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , including:

[0025] A frame body 1, with a support table 2 provided at the upper end of the frame body 1, a mold 5 provided at the upper end of the support table 2, a bottom table 6 provided at the lower end of the mold 5, and two groups of locking structures are provided on the periphery of the upper end of the frame body 1. The locking structure includes a side block 9;

[0026] An inner cavity 10, arranged inside the side block 9. A push plate 18 is arranged inside the inner cavity 10. A return spring 20 is installed outside the push plate 18. A telescopic rod 19 is arranged inside the return spring 20. A limit side hook 13 is arranged at one end outside the return spring 20. Iron blocks 12 are arranged on the upper and lower sides outside the limit side hook 13. Electromagnets 11 are arranged on the upper and lower sides outside the side block 9.

[0027] Please refer to Figure 1 and Figure 4 , an adjusting screw rod 14 is arranged inside the side block 9, and the adjusting screw rod 14 is in threaded connection with the side block 9. The adjusting screw rod 14 is rotatably connected to the push plate 18, and the push plate 18 is used to compress the return spring 20.

[0028] Please refer to Figure 1 and Figure 4 , a control rod 15 is arranged at one end outside the adjusting screw rod 14. A crank 16 is arranged on one side outside the control rod 15, and the crank 16 is rotatably connected to the control rod 15. The crank 16 is used to drive the control rod 15 to rotate.

[0029] Please refer to Figure 4 , an anti-slip ring 17 is arranged outside the crank 16, and the anti-slip ring 17 is connected to the crank 16. The anti-slip ring 17 improves the anti-slip property of the crank 16.

[0030] Please refer to Figure 1 、 Figure 2 and Figure 3 , an inner table 3 is arranged at the upper end of the support table 2, and four limit posts 4 are uniformly distributed along the ring at the upper end of the inner table 3.

[0031] Please refer to Figure 1 、Figure 2 and Figure 3 Inside the lower end of the mold 5, an inner groove 7 is provided, and the inner groove 7 is adapted to the inner table 3. Inside the inner groove 7, four limiting holes 8 are evenly distributed along a ring, and the limiting posts 4 are adapted to the limiting holes 8. The combination of the limiting posts 4 and the limiting holes 8 improves the fixing stability of the mold 5.

[0032] In this solution: Place the mold 5 on the upper end of the frame body 1. The bottom table 6 is close to the supporting table 2. The limiting posts 4 are inserted into the limiting holes 8, and the inner table 3 is combined with the inner groove 7. At this time, the supporting table 2 presses down on multiple limiting side hooks 13 to push them outwards, and the return spring 20 is compressed and deformed under force. When the bottom table 6 is completely attached to the supporting table 2, the return spring 20 resets and pushes the limiting side hooks 13 to clamp and limit the bottom table 6. Then rotate the crank 16 to make the control rod 15 rotate, and further make the adjusting screw 14 push the push plate 18 to squeeze the return spring 20, and further squeeze the limiting side hooks 13, improving the clamping force of the limiting side hooks 13 on the mold 5 and the bottom table 6 and enhancing the stability. When it is necessary to cancel the clamping, loosen the adjusting screw 14 and turn on the electromagnet 11. Under the magnetic force, the iron block 12 drives the limiting side hooks 13 to move towards the electromagnet 11, thereby canceling the clamping and limiting of the bottom table 6 and the mold 5.
