Embodiment 3

[0037] according to Figure 1-Figure 5As shown, a water pump 32 is fixedly connected to one side of the cooling box 3, a water intake pipe 34 is fixedly connected to one side of the water pump 32, a U-shaped tube 33 is fixedly connected to the top of the water pump 32, one end of the U-shaped tube 33 passes through the side wall of the cooling box 3, and one end of the U-shaped tube 33 is fixedly connected to a spray plate 38, one side of the spray plate 38 is fixedly connected to the inner wall of the cooling box 3, one side of the spray plate 38 is fixedly connected to a nozzle, an evaporator 36 is fixedly connected to the top of the base 4, a drain pipe 35 is fixedly connected to the bottom of the evaporator 36, one end of the drain pipe 35 passes through the side wall of the cooling box 3, a connecting pipe 37 is fixedly connected to the top of the evaporator 36, one end of the connecting pipe 37 is fixedly connected to a water pump 2 39, and one side of the water pump 2 39 is fixedly connected to the cooling box 3.

[0038] In this embodiment, the water pump 1 32 can be used to achieve the connection between the U-shaped tube 33 and the water intake pipe 34, so that the water inside the cooling box 3 can be pumped out through the water intake pipe 34 and sent to the water pump 1 32, and then sent to the spray plate 38 through the U-shaped tube 33 to achieve water recycling. The workpiece is sprayed with a nozzle on one side of the spray plate 38 to improve the cooling effect on the workpiece. The base 4 can be used to support and reinforce the bottom of the evaporator 36. The water pump 2 39 can be used to accelerate the flow of water in the cooling box 3 into the connecting pipe 37, and then enter the evaporator 36 for treatment after being guided by the connecting pipe 37. The drain pipe 35 can send the treated water inside the evaporator 36 into the cooling box 3. The water temperature entering the evaporator 36 is relatively high. After being treated by the evaporator 36, it will be lower than the water inlet temperature. Therefore, the water can be cooled to keep the water at a low temperature, thereby ensuring the cooling effect of the water on the workpiece inside the cooling box 3.

[0039] The use method and working principle of the device: First, the water level height inside the cooling box 3 can be monitored by the water level sensor 311. When the water level height inside the cooling box 3 is lower than the preset value, the water level sensor 311 sends a signal to the electric control box 31. After the PLC controller inside the electric control box 31 receives the signal, it alarms through the buzzer installed inside the electric control box 31 to remind the staff to replenish water in time;

[0040] When the whole device is in use, the workpiece obtained by casting the magnesium-aluminum alloy is placed on the limit plate 62, the limit rod 622 overlaps the outer ring surface of the workpiece, the workpiece is initially limited, the L-shaped block 621 is engaged in the engaging groove, the workpiece is secondarily limited, and the workpiece is fixed on the limit plate 62, and then the hydraulic push rod installed between the support rod 24 and the support rod 1 23 drives the support rod 1 23 and the support rod 2 24 to move, adjust the use height of the lifting platform 1, and move the lifting platform 1 downward. At this time, the limit plate 62 and the workpiece are immersed in the cooling water in the cooling box 3, and the water pump 1 32 is used to send the water inside the cooling box 3 into the cavity of the spray plate 38 through the U-shaped tube 33, and then spray it out through the nozzle installed on one side of the spray plate 38. After the soaking is completed, the hydraulic push rod drives the support rod 1 23 The lifting platform 1 is moved in the opposite direction to the support rod 24, and the lifting platform 1 is moved upward. During the upward movement of the lifting platform 1, the servo motor 63 is used to drive the bevel gear 2 65 to rotate, and the bevel gear 2 65 is used to drive the bevel gear 1 6 to rotate, so as to realize the inclination of the limit plate 62 and the workpiece, and drain the excess water. After the drainage is completed, the limit plate 62 returns to a horizontal state, and the electric push rod 56 is used to drive the cleaning bar 53 to move downward until the bottom of the cleaning bar 53 overlaps with the limit plate 62, and the dual-axis motor 55 is used to drive the two threaded rods 511 to rotate, and the guide member 512 moves along the guide frame 51, and the cleaning bar 53 moves on the top of the limit plate 62 to wipe off the residual water on the surface of the limit plate 62. At this time, the fan 52 accelerates the flow of air above the limit plate 62, thereby accelerating the drying of the water on the surface of the workpiece;

[0041] When the workpiece is immersed and cooled in the cooling box 3, the water in the cooling box 3 is pumped out by the water pump 39 and sent to the evaporator 36 through the connecting pipe 37. After evaporation treatment in the evaporator 36, the water is collected in the drain pipe 35. By opening the one-way valve on the drain pipe 35, the water in the drain pipe 35 can be sent to the cooling box 3 to achieve cooling treatment of the water.
