[0018] 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.

[0019] Example 1: Reference Figure 1 and Figure 2 An embodiment of this utility model is provided: a mold for precision forging of a drive shaft, including a base 1, mounting rods 3 are provided at the four corners of the upper surface of the base 1, and a top plate 4 is installed on the upper end of the four sets of mounting rods 3. Two sets of cylinders 5 are provided on the lower surface of the top plate 4. Mounting frames 6 are provided on the lower end of the two sets of cylinders 5 and the upper surface of the base 1. A mold groove 7 is provided on the side of the two sets of mounting frames 6 that are close to each other. Fixing components 8 are provided on the front and rear sides of the two sets of mounting frames 6. Specifically, by setting the base 1 in a suitable position, then setting the mold groove 7 in two sets of mounting frames 6, and fixing the mold groove 7 in the mounting frames 6 by the fixing component 8, then opening two sets of cylinders 5, and pushing the upper mounting frames 6 and the mold groove 7 to move by the cylinders 5, so that the two sets of mounting frames 6 fit together, thereby forming the mold groove 7.

[0020] Reference Figure 4 All four sets of fixing components 8 include locking bolts 801. The locking bolts 801 are installed on the front side of the mounting frame 6 through a threaded structure, and the mold groove 7 has matching threaded holes 802 on both the front and rear sides. Specifically, the threaded connection facilitates quick disassembly and replacement of mold slot 7, improving assembly and maintenance efficiency while reducing the structural complexity and maintenance inconvenience caused by traditional welding fixing methods.

[0021] Reference Figure 1 Stabilizing seats 2 are provided at the four corners of the lower surface of the base 1; Specifically, the stabilizer 2 can act as a shock absorber and buffer, reducing the impact force on the base 1 and internal components, effectively extending the service life of the device, and improving the reliability and precision of the molding process.

[0022] Reference Figure 3 The upper mounting frame 6 has mounting pieces 9 at each of its four corners, and each of the four mounting pieces 9 has a guide rod 10 on its lower surface. The lower mounting frame 6 has positioning pieces 11 at each of its four corners, and each of the four positioning pieces 11 has a slot in the middle that matches the guide rod 10. The lower ends of the four guide rods 10 are all tapered. Specifically, through the cooperation of the slots opened in the guide rod 10 and the positioning plate 11, when the upper mounting frame 6 moves, it can be ensured that the upper mounting frame 6 will be restricted by the guide rod 10, ensuring the stability of the movement of the mounting frame 6 and ensuring the sealing effect of the mold groove 7. Through the tapered structure set on the lower side of the guide rod 10, it can still be inserted into the slot of the positioning plate 11 when the guide rod 10 is offset, and then the movement of the guide rod 10 is restricted.

[0023] Reference Figure 1 The two sets of mounting frames 6 are equipped with heat sinks 12 on both the left and right sides, and cooling fans 13 are installed on the side of the two sets of heat sinks 12 that are far apart from each other. All four sets of heat sinks 12 are made of copper. Specifically, the copper heat sink 12 can enhance the heat conduction effect. By increasing the heat dissipation area, the heat sink 12 can quickly conduct the heat generated by the mold groove 7 during operation. Combined with the forced convection of the cooling fan 13, it can further improve the cooling efficiency and accelerate the molding speed of the material.

[0024] Example 2: Reference Figure 5 Each of the four sets of fixing components 8 includes two sets of insert rods 803. The two sets of insert rods 803 are movably inserted into the front side of the two sets of mounting frames 6. A connecting piece 804 is installed on the front side of the two sets of insert rods 803, and a handle 805 is installed on the front side of the connecting piece 804. Slots matching the insert rods 803 are provided on both the front and rear sides of the two sets of mold grooves 7. Two sets of return springs 806 are provided between the connecting piece 804 and the mounting frame 6. Specifically, after the mold slot 7 is set in the mounting frame 6, the reset spring 806 drives the insertion rod 803 to be inserted into the slot opened in the mold slot 7 to fix the mold slot 7. When it is necessary to remove the mold slot 7, pull the handle 805, and the connecting piece 804 drives the two sets of insertion rods 803 to move, thereby releasing the fixation of the mold slot 7 and making it convenient to replace different mold slots 7.

[0025] Working principle: The base 1 is set in a suitable position, and then two sets of matching mold slots 7 are installed in two sets of mounting frames 6. The mold slots 7 are fixed by the fixing components 8. Then, the material is placed in the two sets of mold slots 7. By opening the cylinder 5, the upper mounting frame 6 is moved. Then, the mounting frame 6 is moved stably by the guide rod 10 and the positioning plate 11, so that the two sets of mounting frames 6 and mold slots 7 fit tightly together, ensuring the molding effect of the material in the mold slots 7. Then, the cooling fan 13 is turned on, and the heat in the mold slots 7 is absorbed by the heat sink 12 and then dissipated by the cooling fan 13, ensuring that the material in the mold slots 7 cools down and is molded quickly.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
