[0033] As described in the background technology, forging is a combination of forging and stamping. It is a forming method that uses the hammer, anvil, punch of a forging machine or a die to apply pressure to the blank to cause it to undergo plastic deformation, thereby obtaining a part of the desired shape and size. During the use of the forging die, since the product is bent and formed after heating, the forging head will continue to heat up due to multiple contacts with the part to be formed. The existing technology often manually applies coolant to the forging head repeatedly to cool and lubricate it. However, this method of manually applying coolant has low production efficiency and is likely to affect the service life of the die and the stability of the product forming size.

[0034] Based on this, please refer to Figure 1The present invention provides a forging die cooling device 100 that effectively addresses the aforementioned technical issues. Specifically, it rapidly cools and lubricates the forging head 13, ensuring that the molded part 200 remains lubricated and at a constant temperature. This improves the mold's service life, stabilizes the product's molded dimensions, and enhances production efficiency. The forging die cooling device 100 is described in detail below.

[0035] Please refer to Figure 1 , Figure 1 The schematic diagram of the structure of the forging die cooling device 100 provided in this embodiment is shown in FIG. Figure 1 The forging die cooling device 100 includes a die body 10 and a cooling device 20. The die body 10 includes an upper die 11, a lower die 12 and a forging head 13. The upper die 11 and the lower die 12 are spaced apart, and the forging head 13 is arranged on the side of the upper die 11 close to the lower die 12; the cooling device 20 includes a coolant supply element 21, a solenoid valve 22 and a coolant injection pipe 23. The coolant supply element 21 is connected to the solenoid valve 22, the solenoid valve 22 is arranged on the upper die 11, and the coolant injection pipe 23 is connected to the solenoid valve 22 for spraying coolant toward the forging head 13.

[0036] That is to say, the coolant supply element 21 is used to transport coolant, and under the control of the solenoid valve 22, the coolant injection pipe 23 automatically injects coolant to the forging head 13; through the setting of the solenoid valve 22, when forging the formed part 200, the time for automatic coolant injection can be set according to the forging frequency, thereby achieving the effect of quickly cooling and lubricating the forging head 13, so that the formed part 200 is always kept lubricated and at room temperature, thereby improving the service life of the mold and the stability of the product molding size, and compared with the manual application of coolant, it also significantly improves production efficiency.

[0037] In this embodiment, the coolant supply element 21 is spaced apart and disposed on the same side of the lower die 12 and the upper die 11. The cooling device 20 also includes a coolant connection pipe 24, which is in communication with both the coolant supply element 21 and the solenoid valve 22. As will be readily appreciated, by locating the coolant supply element 21 on one side of the die body 10, the coolant connection pipe 24 can be conveniently connected to the solenoid valve 22, thereby facilitating coolant delivery without affecting the normal forging operation of the die body 10.

[0038] In order to further improve the cooling effect of the forging head 13, the number of solenoid valves 22 and coolant injection pipes 23 is multiple, and multiple solenoid valves 22 are arranged at intervals on the upper mold 11, and each solenoid valve 22 is provided with at least one coolant injection pipe 23; the coolant supply element 21 is connected to multiple solenoid valves 22 at the same time.

[0039] It should be noted that the specific number and location of the multiple solenoid valves 22 can be adjusted according to the specific shape, structure and location of the forging head 13 .

[0040] Specifically, in this embodiment, there are two solenoid valves 22, which are disposed on opposite sides of the upper die 11; there are four coolant injection pipes 23, and each solenoid valve 22 is provided with two coolant injection pipes 23. It can be understood that by arranging the two solenoid valves 22 opposite each other and each solenoid valve 22 being connected to two coolant injection pipes 23, the working area of ​​the forging head 13 can be effectively covered. By adjusting the injection angle of the coolant injection pipes 23, the cooling area of ​​the forging head 13 can be increased, thereby improving the cooling and lubrication effects.

[0041] Correspondingly, in this embodiment, the number of the coolant connecting pipes 24 is also two, and the two coolant connecting pipes 24 are respectively connected to the two solenoid valves 22.

[0042] Of course, in other embodiments, a solenoid valve 22 may be provided on each side of the upper die 11, that is, four solenoid valves 22 are provided. Accordingly, four coolant connecting pipes 24 are provided, and the coolant supply element 21 is connected to the four solenoid valves 22 via the four coolant connecting pipes 24. In this case, the number of coolant injection pipes 23 connected to each solenoid valve 22 may be one or more. This arrangement further increases the cooling coverage area of ​​the forging head 13, thereby further improving the cooling and lubrication effects.

[0043] Please continue to combine Figure 1 In this embodiment, one end of each coolant injection pipe 23 is connected to the side of the solenoid valve 22 away from the upper die 11, and each coolant injection pipe 23 is bent toward the forging head 13. This bending arrangement can better adjust the angle of the coolant injection pipe 23 toward the forging head 13, shorten the coolant injection path, improve the injection efficiency, and further improve production efficiency.

[0044] During the forging process, in order to improve the stability of the formed part 200 during the movement of the upper die 11 toward the lower die 12, in this embodiment, the die body 10 also includes a plurality of guide columns 14, and the plurality of guide columns 14 are arranged at intervals on the side of the upper die 11 close to the lower die 12; the lower die 12 is provided with a plurality of guide holes 121, and the plurality of guide holes 121 are used to cooperate with the plurality of guide columns 14.

[0045] It should be noted that, in this embodiment, the number of the guide posts 14 and the number of the guide holes 121 are both four, and the four guide posts 14 are respectively distributed at the four corners of the upper mold 11. Figure 1As shown, the coolant injection pipes 23 provided on the two solenoid valves 22 are respectively located between the two guide columns 14. In this way, the guide columns 14 can play a certain protective role on the coolant injection pipes 23 to prevent other components or the external environment from affecting the coolant injection pipes 23 during operation.

[0046] After the forging process is completed, the molded part 200 is conveniently removed from the mold. In this embodiment, the forging die cooling device 100 further includes a side pusher 30, which is disposed on the lower die 12 and is used to push the molded part 200 out of the lower die 12. In other words, after forging is completed, the side pusher 30 pushes the molded part 200 out from one side of the lower die 12, thereby improving work efficiency.

[0047] In order to prevent the side thrust device 30 from interfering with parts of the die body 10 during the forging process, the forging die cooling device 100 further includes a support block 40. The support block 40 is disposed on one side of the lower die 12, and the side thrust device 30 is disposed on the support block 40. As will be readily understood, the support block 40 can also support the side thrust device 30, thereby improving stability during the side thrust process and facilitating disassembly and maintenance of the side thrust device 30.

[0048] Specifically, the side thrust device 30 includes a side thruster 31 and a side thrust plate 32. The side thruster 31 is disposed on the lower mold 12, and the side thrust plate 32 is connected to the side thruster 31. It should be noted that in this embodiment, the side thruster 31 is specifically a cylinder. Of course, in other embodiments, the side thruster 31 can also be other driving structures such as a hydraulic cylinder or an electric push rod.

[0049] Furthermore, to facilitate the unloading process after the molded part 200 is lifted, the forging die cooling device 100 further includes a lifting device 50, which is disposed on the lower die 12 and is used to lift the molded part 200 on the lower die 12. In this embodiment, it is easy to understand that the molded part 200 can be first lifted by the lifting device 50, and then the molded part 200 can be pushed sideways by the side pushing device 30, thereby further improving production efficiency.

[0050] Specifically in this embodiment, the jacking device 50 can include a jacking device and a jacking plate. The jacking device is arranged on the base of the lower mold 12 and is connected to the jacking plate. The jacking plate is arranged on the forging platform of the lower mold 12, and the jacking plate can be used to support the formed part 200.

[0051] It should also be noted that, in this embodiment, the jacking device is specifically a cylinder. Of course, in other embodiments, the jacking device may also be other driving structures such as a hydraulic cylinder or an electric push rod.

[0052] To sum up, an embodiment of the present invention provides a forging die cooling device 100, which includes a die body 10 and a cooling device 20. The die body 10 includes an upper die 11, a lower die 12 and a forging head 13. The upper die 11 and the lower die 12 are spaced apart, and the forging head 13 is arranged on the side of the upper die 11 close to the lower die 12; the cooling device 20 includes a coolant supply element 21, a solenoid valve 22 and a coolant injection pipe 23. The coolant supply element 21 is connected to the solenoid valve 22, the solenoid valve 22 is arranged on the upper die 11, and the coolant injection pipe 23 is connected to the solenoid valve 22 for spraying coolant toward the forging head 13. That is to say, the coolant supply element 21 is used to transport coolant, and under the control of the solenoid valve 22, the coolant injection pipe 23 automatically injects coolant to the forging head 13; through the setting of the solenoid valve 22, when forging the formed part 200, the time for automatic coolant injection can be set according to the forging frequency, thereby achieving the effect of quickly cooling and lubricating the forging head 13, so that the formed part 200 is always kept lubricated and at room temperature, thereby improving the service life of the mold and the stability of the product molding size, and compared with the manual application of coolant, it also significantly improves production efficiency.

[0053] The above description is merely a specific embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations.
