DETAILED DESCRIPTION

[0034] The embodiments of the present application will be described in detail below with the accompanying drawings and examples, so that the realization process of how to apply technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

[0035] As Figures 1-4As shown, an automatic cooling device for forging dies includes a lower die 1 and an automatic water spraying mechanism disposed on one side of the lower die 1. The automatic water spraying mechanism can cool the die after use for future use. The automatic water spraying mechanism includes a water tank 5, a liquid storage ring 4 fixedly disposed at one end of the lower die 1, a liquid delivery pipe 9 for connecting the liquid storage ring 4 and the water tank 5, and a photoelectric switch 8. An upper die 3 for die stamping is disposed at one end of the lower die 1, and the photoelectric switch 8 is used for height detection of the upper die 3.

[0036] A water pump is fixedly installed inside the water tank 5. The water pump is electrically connected to the photoelectric switch 8. The water tank 5 is connected to the liquid storage ring 4 through the liquid delivery pipe 9, so that the water tank 5 can use its internal water pump to deliver coolant for mold cooling to the inside of the liquid storage ring 4. This allows the liquid storage ring 4 to spray coolant outward, thereby achieving the effect of cooling the mold. The photoelectric switch 8 is set to detect the upper mold 3. When the upper mold 3 is pressed down to the position, the upper mold 3 automatically returns and triggers the photoelectric switch 8, which then opens the solenoid valve 10 and the water pump connected to it by the electrical signal. Then, the coolant can be quickly delivered to the inside of the liquid storage ring 4 through the liquid delivery pipe 9. Conversely, when the upper mold 3 continues to press down, the photoelectric switch 8 will not trigger the water pump and the solenoid valve 10 will close, thus preventing the liquid storage ring 4 from spraying coolant.

[0037] Furthermore, such as Figure 1 As shown, the lower mold 1 is connected to the upper mold 3 via multiple hydraulic drive rods 2. The two ends of the hydraulic drive rods 2 are fixedly connected to the lower mold 1 and the upper mold 3 respectively. The hydraulic drive rods 2 are used to drive the upper mold 3. The arrangement of multiple hydraulic drive rods 2 can drive the upper mold 3 to move vertically, so that the upper mold 3 can be used to process the material inside the lower mold 1. At the same time, the extension and retraction of the hydraulic drive rods 2 can be restricted so that the upper mold 3 will not contact the upper surface of the lower mold 1 after it falls, thereby avoiding the impact of the upper mold 3 falling on the liquid storage ring 4 and the equipment on it.

[0038] Furthermore, such as Figure 2As shown, the bottom of the water storage tank 5 is fixedly provided with a moving base 6 for position adjustment, one side of the moving base 6 is fixedly installed with a support rod 7, the photoelectric switch 8 is fixedly arranged at the end of the support rod 7 away from the moving base 6, and the time relay 11 is fixedly installed at the middle of the support rod 7. The photoelectric switch 8 is electrically connected with the time relay 11 through a power line, the time relay 11 is electrically connected with the electromagnetic valve 10 through a connecting line 12, the electromagnetic valve 10 is fixedly connected with the infusion tube 9, and the electromagnetic valve 10 is used for opening and closing the infusion tube 9. The setting of the support rod 7 can fix the positions of the photoelectric switch 8 and the time relay 11, so that the photoelectric switch 8 can detect the upper mold 3 at a certain height, and the photoelectric switch 8 can be electrically connected with the electromagnetic valve 10 through the time relay 11, so that the signal transmission is more stable. The moving base 6 can not only fix the support rod 7, but also can be directly pushed when the staff needs to move the position of the water storage tank 5.

[0039] Further, as shown in the drawings, Figures 3-4 As shown, the side of the liquid storage ring 4 is rotatably connected with a plurality of spray heads 401, the spray heads 401 are communicated with the inside of the liquid storage ring 4 for spraying the cooling liquid, and the lower mold 1 and the inside of the liquid storage ring 4 are respectively provided with an extrusion cavity 13 for product stamping and a retention cavity 14 for retaining the cooling liquid. The retention cavity 14 is left in the inside of the liquid storage ring 4, so that the cooling liquid can be retained for a period of time after flowing into the inside of the liquid storage ring 4 through the infusion tube 9, and then sprayed outward by the spray heads 401 under the action of pressure. Meanwhile, the angle of the spray heads 401 can be adjusted to meet different cooling requirements.

[0040] In this embodiment, as shown in the drawings, Figures 1-4 The principle of the device for automatically cooling the forging mold provided by the embodiment is as follows:

[0041] The water storage tank 5 is communicated with the liquid storage ring 4 through the infusion tube 9, so that the water pump in the water storage tank 5 can deliver the cooling liquid for cooling the mold to the inside of the liquid storage ring 4, so that the liquid storage ring 4 can spray the cooling liquid outward to achieve the effect of cooling the mold. The setting of the photoelectric switch 8 can detect the upper mold 3, and when the upper mold 3 is pressed to a position, the automatic return of the upper mold 3 can trigger the photoelectric switch 8, so that the photoelectric switch 8 can open the electromagnetic valve 10 and the water pump electrically connected with the electromagnetic valve 10, and then the cooling liquid can quickly flow into the inside of the liquid storage ring 4 through the infusion tube 9.
