Description

Technical Field

[0001] This utility model belongs to the field of precision casting technology, and specifically relates to a cooling device for precision casting. Background Technology

[0002] Precision casting is a process in which metal is melted into a liquid that meets certain requirements and poured into a mold. After cooling and solidification, and cleaning, a casting with a predetermined shape, size and performance is obtained. Because the casting blank is almost formed, it can achieve the purpose of eliminating or minimizing machining, which reduces costs and reduces production time to a certain extent. After casting is completed, the casting needs to be cooled.

[0003] Existing cooling devices involve immersing the workpiece in water and cooling it through water cooling. However, the cooling characteristics of water are very sensitive to changes in water temperature. Changes in water temperature will cause changes in the cooling rate, resulting in local overheating or overcooling of the workpiece, which will cause deformation and distortion of the workpiece. Therefore, we provide a cooling device for precision casting. Utility Model Content

[0004] The purpose of this invention is to provide a cooling device for precision casting to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for precision casting, comprising a cooling pool, a I-beam frame fixedly connected to the cooling pool, electric telescopic rods fixedly connected to both sides of the top of the I-beam frame, a placement frame fixedly connected to the bottom of the electric telescopic rods, water inlet holes provided on the surface and bottom of the placement frame, a motor fixedly installed at the bottom of the right side of the cooling pool, a stirring rod fixedly connected to the output end of the motor, and stirring blades fixedly connected to the surface of the stirring rod.

[0006] By adopting the above scheme, the stirring rod is driven by the motor to rotate, and the stirring blade is driven by the stirring rod to rotate. The stirring blade stirs the water, thereby accelerating the water flow rate, breaking the vapor film formed on the surface of the workpiece during the cooling process, allowing the water to come into direct contact with the surface of the workpiece, breaking the temperature gradient inside the water, making the heat distribution more uniform, preventing local overheating or overcooling, and greatly improving the cooling efficiency.

[0007] In a preferred embodiment of a cooling device for precision casting, a heat-conducting plate is fixedly connected to the back of the cooling pool, and a set of heat dissipation fins are provided on the surface of the heat-conducting plate.

[0008] Using the above solution, the heat energy in the water is transferred to the heat dissipation fins through the heat conduction plate. Since the heat dissipation fins can form a larger heat dissipation surface, the heat can be transferred to the air more quickly, preventing the water temperature inside the cooling pool from getting too high and thus reducing the cooling effect.

[0009] In a preferred embodiment of a cooling device for precision casting, slides are fixedly connected to both sides of the inner cavity of the cooling pool, and a fine filter screen is slidably connected between the two slides.

[0010] By adopting the above scheme and setting up a fine filter screen, impurities in the water are filtered during the water discharge process, thereby improving the water utilization rate.

[0011] In a preferred embodiment of a cooling device for precision casting, one end of the stirring rod is movably connected to a bearing, and one side of the bearing is fixedly connected to one side of the inner cavity of the cooling pool.

[0012] By adopting the above solution, the bearing is used to limit one end of the stirring rod, preventing one end of the stirring rod from being suspended in the air and thus causing vibration.

[0013] In a preferred embodiment of a cooling device for precision casting, a water outlet pipe is connected to the bottom of the left side of the cooling pool, and a control valve is provided on the surface of the water outlet pipe.

[0014] By using the above method, the water inside the cooling pool can be quickly drained by controlling the valve settings and the speed of water flow output.

[0015] In a preferred embodiment of a cooling device for precision casting, a PLC controller is fixedly connected to the front end of the right side of the cooling pool, and the PLC controller is electrically connected to the electrical equipment via a connecting line.

[0016] By adopting the above solution, the PLC controller can be set to start and stop the electrical equipment in real time, making it convenient for users to operate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses a motor to drive a stirring rod to rotate, which in turn drives the stirring blades to rotate. The stirring blades stir the water, thereby accelerating the water flow rate and breaking the vapor film formed on the surface of the workpiece during the cooling process. This allows the water to come into direct contact with the surface of the workpiece, breaking the temperature gradient inside the water and making the heat distribution more uniform. This prevents local overheating or overcooling and greatly improves the cooling efficiency.

[0019] 2. This utility model uses a heat-conducting plate to transfer heat energy from the water to the heat dissipation fins. Because the heat dissipation fins can form a larger heat dissipation surface, the heat can be transferred to the air more quickly, preventing the water temperature inside the cooling pool from getting too high and thus reducing the cooling effect.

[0024] Please see Figure 1-3 A cooling device for precision casting includes a cooling tank 1, see Figure 2 As shown, a heat-conducting plate 11 is fixedly connected to the back of the cooling pool 1. A set of heat dissipation fins 12 are provided on the surface of the heat-conducting plate 11. The heat energy in the water is conducted to the heat dissipation fins 12 through the heat-conducting plate 11. Because the heat dissipation fins 12 can form a larger heat dissipation surface, the heat can be transferred to the air more quickly, preventing the water temperature inside the cooling pool 1 from becoming too high, thereby reducing the cooling effect. A frame 2 is fixedly connected to the cooling pool 1. Electric telescopic rods 3 are fixedly connected to both sides of the top of the frame 2. A placement frame 4 is fixedly connected to the bottom of the electric telescopic rod 3. Water inlet holes are opened on the surface and bottom of the placement frame 4. A motor 8 is fixedly installed at the bottom right side of the cooling pool 1. A stirring rod 9 is fixedly connected to the output end of the motor 8. A stirring blade 10 is fixedly connected to the surface of the stirring rod 9. See Figure 3 As shown, slide rails 6 are fixedly connected to both sides of the inner cavity of the cooling pool 1, and a fine filter screen 7 is slidably connected between the two slide rails 6. Through the setting of the fine filter screen 7, impurities in the water are filtered during the water discharge process, improving the water utilization rate. The motor 8 drives the stirring rod 9 to rotate, and the stirring rod 9 drives the stirring blade 10 to rotate. The stirring blade 10 stirs the water, thereby accelerating the water flow rate, breaking the vapor film formed on the surface of the workpiece during the cooling process, so that the water and the surface of the workpiece come into direct contact, breaking the temperature gradient inside the water, making the heat distribution more uniform, preventing local overheating or overcooling, and greatly improving the cooling efficiency.

[0025] See Figure 3As shown, a bearing is movably connected to one end of the stirring rod 9, and one side of the bearing is fixedly connected to one side of the inner cavity of the cooling tank 1. The bearing limits the movement of one end of the stirring rod 9, preventing it from being suspended and thus causing vibration. Figure 1 As shown, a water outlet pipe 5 is connected to the bottom of the left side of the cooling pool 1. A control valve is installed on the surface of the water outlet pipe 5. By controlling the water flow rate through the valve, the water inside the cooling pool 1 can be quickly drained. Figure 2 As shown, a PLC controller 13 is fixedly connected to the front end of the right side of the cooling pool 1. The PLC controller 13 is electrically connected to the electrical equipment through a connecting line. The PLC controller 13 can be set to start and stop the electrical equipment in real time, which is convenient for users to operate.

[0026] In use, the workpiece to be cooled is first placed inside the placement frame 4. After placement, the electric telescopic rod 3 is activated, which moves the placement frame 4 downwards, and the placement frame 4 moves the workpiece downwards until the workpiece inside the placement frame 4 is completely submerged in water. The movement then stops (the electric telescopic rod 3 is used to move the placement frame 4 up and down, making it easy to pick up and place the workpiece). Then, during the workpiece cooling process, the motor 8 is activated, which converts electrical energy into mechanical energy and drives the stirring rod 9 to rotate. The stirring rod 9 drives the stirring blade 10 to rotate, which stirs the water and accelerates the water flow. This breaks the vapor film formed on the surface of the workpiece during the cooling process, allowing the water to come into direct contact with the surface of the workpiece. This breaks the temperature gradient inside the water, making the heat distribution more uniform and preventing local overheating or overcooling, greatly improving the cooling efficiency. Finally, the heat energy in the water is conducted to the heat dissipation fins 12 through the heat conduction plate 11. Because the heat dissipation fins 12 can form a larger heat dissipation surface, the heat can be transferred to the air more quickly, preventing the water temperature inside the cooling pool 1 from becoming too high and thus reducing the cooling effect.
