[0025] 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.

[0026] Example 1

[0027] Please see Figure 1-4 As shown, a ring forging die includes a support platform 1, and a U-shaped frame 2 is fixedly connected to the top of the support platform 1.

[0028] A lower mold 3 is fixedly installed at the top center of the support platform 1, and an upper mold 4 is installed on the lower mold 3. A hydraulic cylinder 7 is fixedly installed at the top of the U-shaped frame 2, and a connecting rod 5 is fixedly connected to the output end of the hydraulic cylinder 7. The bottom end of the connecting rod 5 passes through the upper part of the interior of the U-shaped frame 2, and the bottom end of the connecting rod 5 is fixedly connected to the top center of the upper mold 4. A guide assembly is provided between the connecting rod 5 and the U-shaped frame 2. A demolding assembly is provided between the U-shaped frame 2, the support platform 1, and the lower mold 3. The demolding assembly is installed with the guide assembly. During operation, the bottom of the support platform 1 is first placed on a flat ground to stabilize the mold. After stabilization, the heated mold is then placed on the ground. The raw material to be forged is placed inside the lower mold 3. Then, the hydraulic cylinder 7 drives the connecting rod 5 and the upper mold 4 to move. After the raw material is added into the lower mold 3, forging is carried out by the movement of the upper mold 4, so that the raw material is forged into a ring-shaped forging inside the lower mold 3. The movement of the upper mold 4 can be guided by the guide component, making the movement of the upper mold 4 more stable. At the same time, after forging, the demolding component and the guide component can cooperate to assist the demolding of the forging inside the lower mold 3 by moving the upper mold 4 downward, making the mold easy to demold after forging, thereby speeding up the demolding efficiency of the workers and improving production efficiency.

[0029] The guiding assembly includes two slide grooves 10 respectively opened on the left and right sides inside the U-shaped frame 2. A connecting plate 6 is slidably connected inside the slide groove 10. The connecting plate 6 is fixedly connected to the connecting rod 5. The connecting plate 6 is T-shaped and has a threaded hole on one side. During operation, the movement of the connecting rod 5 can be guided by the connecting plate 6 through the connection between the T-shaped connecting plate 6 and the connecting rod 5. Since one side of the connecting plate 6 is placed inside the slide groove 10, the movement of the connecting rod 5 is guided by the sliding connection between the connecting plate 6 and the slide groove 10, and the movement of the upper mold 4 is more stable.

[0030] The demolding assembly includes a through-type limiting groove 9 formed on one side inside the slide groove 10. A limiting block 11 is slidably connected inside the limiting groove 9. One side of the limiting block 11 extends into the slide groove 10, and one side of the limiting block 11 is in contact with one side of the connecting plate 6. An installation bolt 8 passes through the limiting block 11, and the installation bolt 8 is adapted to a threaded hole. During operation, the threaded connection between the installation bolt 8 and the threaded hole allows the connecting plate 6 and the limiting block 11 to be connected and fixed. After the connecting plate 6 and the limiting block 11 are installed and fixed, the movement of the connecting plate 6 can drive the limiting block 11 to slide in the limiting groove 9.

[0031] The lower surface of the slide groove 10 is provided with a through groove 13. A piston 14 is slidably connected inside the through groove 13. A pressing rod 15 is fixedly connected to the top of the piston 14. The top of the pressing rod 15 is fixedly connected to the bottom of the limiting block 11. During operation, the sliding of the limiting block 11 drives the pressing rod 15 to move, and after the pressing rod 15 moves, it drives the piston 14 to slide and compress the gas inside the through groove 13.

[0032] An air vent 17 is provided at the center of the support platform 1. Multiple through-holes and T-shaped air vents 21 are provided on the upper surface of the air vent 17. A piston 22 is slidably connected inside the air vent 21. A demolding rod 20 is fixedly connected to the top of the piston 22. A demolding template 19 is fixedly connected to the top of the demolding rod 20. The demolding template 19 is adapted to the air vent 21. During operation, the compressed gas inside the air vent 17 enters the air vent 21 and compresses the piston 22. After being compressed, the piston 22 slides inside the air vent 21. The sliding of the piston 22 drives the demolding rod 20 and the demolding template 19 to move and move the forged part inside the lower mold 3 to assist in demolding. This makes the demolding speed of the mold faster and facilitates the demolding of the mold.

[0033] U-shaped connecting pipes 12 are fixedly installed on both the left and right sides of the bottom of the support platform 1. The connecting pipes 12 are connected to the through groove 13 through the ventilation groove 16, and the connecting pipes 12 are connected to the air outlet groove 17 through the through hole 18. During operation, the gas squeezed inside the through groove 13 can be transferred to the air outlet groove 17 through the U-shaped connecting pipes 12, the ventilation groove 16 and the through hole 18 to assist in demolding.

[0034] The lower mold 3 has an annular forging cavity inside, and the upper surface of the forging cavity extends to the outside of the lower mold 3. The upper mold 4 is inserted into the forging cavity and is slidably connected to the lower mold 3. During operation, the annular forging cavity facilitates the forging of annular forgings, and the upper mold 4 can move inside the lower mold 3 for forging.

[0035] Example 2

[0036] Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, a spiral cooling pipe 23 is fixedly installed on the outer surface of the lower mold 3. Both the upper and lower ends of the spiral cooling pipe 23 are threaded with pipe caps. During operation, coolant is injected into the spiral cooling pipe 23 so that the spiral cooling pipe 23 can cool the forging inside the lower mold 3 after forging, and can accelerate the cooling and demolding process of the forging after forging, and make the mold more effective. At the same time, by rotating the pipe cap of the spiral cooling pipe 23, the coolant inside the spiral cooling pipe 23 can be easily drained, replaced and injected, making it convenient to use.
