Description

Technical Field

[0001] This utility model relates to the field of aluminum industrial production technology, and in particular to a baffle for an aluminum molten casting chute. Background Technology

[0002] Aluminum molten aluminum casting chute baffle is an equipment component used in aluminum industry production. It is mainly used to control and guide the flow of high-temperature aluminum molten metal during the casting process. This baffle is usually installed at key positions in the chute to help adjust the flow direction, flow rate, and amount of aluminum molten metal distributed to different molds or areas.

[0003] Traditional aluminum molten casting chute systems primarily rely on electrically driven devices to adjust the position of baffles, thereby controlling the flow direction and velocity of the molten aluminum. While this automated design performs well under normal operating conditions, motor failures or sudden power outages are unavoidable in actual operation. In such situations, failure to adjust the baffle position promptly can not only lead to production interruptions but also potentially cause serious safety hazards and product quality problems. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a baffle for an aluminum molten casting chute.

[0005] Technical Solution: A baffle for an aluminum molten casting chute includes a chute, a support frame, a guide rod, a first screw, a lifting plate, a baffle, a first gear, a second gear, a motor, a lifting block, and a protective component. The chute guides the aluminum molten material from one position to another. A support frame is installed on the outside of the chute. A guide rod is connected to the left side of the support frame, and the first screw is rotatably connected to the right side of the support frame. A lifting plate is slidably connected to the support frame. The left end of the lifting plate is slidably connected to the guide rod, and the right end is threadedly connected to the first screw. A baffle located inside the chute is connected to the bottom of the lifting plate. The first gear is connected to the upper end of the first screw. A lifting block is slidably connected to the upper right side of the support frame. A motor is installed on the lifting block, and a second gear meshing with the first gear is connected to the output shaft of the motor. A protective component is provided at the lower part of the support frame.

[0006] As an improvement to the above solution, the outer side of the baffle that contacts the chute is equipped with a high-temperature resistant sealing strip.

[0007] As an improvement to the above solution, the protective component includes a protective frame, a pin, a rotating rod, and a handle. A slot is provided on the lower right side of the support frame, and the protective frame is slidably engaged at the slot. The protective frame is fixed to the support frame on both sides by pins. The lower end of the first screw is connected to a rotating rod, which extends through the slot and is rotatably connected to a handle located in the slot on the front and rear sides.

[0008] As an improvement to the above solution, it also includes a sliding frame and springs. The sliding frame is slidably connected to the bottom of the lifting block. Two sets of symmetrical slots are opened on the upper right side of the support frame, with two slots in each set. The sliding frame engages with the upper slots in the initial state to fix the position of the lifting block. Two springs are connected between the sliding frame and the inside of the lifting block.

[0009] As an improvement to the above solution, a handle is rotatably connected to the bottom right side of the sliding frame.

[0010] As an improvement to the above solution, it also includes a connecting block, a second screw, and a locking block. The connecting block is connected to the rear side of the lifting block, and the second screw is rotatably connected to the upper part of the support frame near the connecting block. A square locking block is threaded onto the second screw. The locking block is in close contact with the wall of the support frame and is limited by the support frame. The locking block abuts against the connecting block.

[0011] Beneficial effects: 1. In the event of motor failure or power outage, the height of the second gear can be adjusted to disengage it from the first gear, and then the first screw can be rotated manually to adjust the position of the baffle, ensuring the continuity and safety of production. This dual-mode (automatic / manual) design greatly enhances the reliability and adaptability of the system.

[0012] 2. By adding a locking mechanism consisting of a connecting block, a second screw, and a locking block, the position of the lifting block can be stably fixed when needed, preventing accidental slippage and ensuring the safety and stability of the equipment operation.

[0013] 3. The design of protective components (such as protective frames, pins, etc.) allows for quick switching to manual mode in case of motor failure, and is easy to disassemble and reinstall, facilitating maintenance and emergency handling. Attached Figure Description

[0020] 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.

[0021] Example: A baffle for an aluminum molten casting chute, such as Figures 1-4 As shown, the device includes a chute 1, a support frame 2, a guide rod 3, a first screw 4, a lifting plate 5, a baffle 6, a first gear 7, a second gear 8, a motor 9, a lifting block 10, and protective components. The chute 1 guides molten aluminum from one position to another. A support frame 2 is installed on the outside of the chute 1 to provide structural support for the entire device. A guide rod 3 is welded to the left side inside the support frame 2, and the first screw 4 is rotatably connected to the right side inside the support frame 2. A lifting plate 5 is slidably connected inside the support frame 2. The left end of the lifting plate 5 is slidably connected to the guide rod 3, and the right end is threadedly connected to the first screw 4. A baffle 6 located inside the chute 1 is connected to the bottom of the lifting plate 5 to control the opening and closing of the chute 1 channel and to regulate the flow rate of molten aluminum. The outer side of the baffle 6 that contacts the chute 1 is equipped with a high-temperature resistant sealing strip to ensure a tight seal between the two. The fit effectively prevents aluminum molten material leakage and maintains the airtightness of the channel. The upper end of the first screw 4 is connected to the first gear 7, and the upper right side of the support frame 2 is slidably connected to the lifting block 10. The lifting block 10 is bolted to the motor 9, and the output shaft of the motor 9 is connected to the second gear 8 that meshes with the first gear 7. By starting the motor 9, the output shaft of the motor 9 rotates, driving the first gear 7 and the second gear 8 to rotate, thereby driving the first screw 4 to rotate, which in turn drives the lifting plate 5 and the baffle 6 to move upward along the guide rod 3, which can control the opening of the channel in the chute 1. The operator controls the motor 9 to run in reverse, that is, the first screw 4 can be reversed to drive the lifting plate 5 and the baffle 6 to move downward to close. The lower part of the support frame 2 is equipped with a protective component, which allows manual adjustment of the position of the baffle 6 in case of motor 9 failure, ensuring the reliability and safety of the system.

[0022] like Figure 1 , Figure 2 and Figure 4As shown, the protective components include a protective frame 13, a pin 14, a rotating rod 15, and a handle 16. A slot is provided on the lower right side of the support frame 2, and the protective frame 13 is slidably engaged at the slot to ensure protection of the internal components when not in use. The left and right sides of the protective frame 13 are fixed to the support frame 2 by the pin 14 for easy disassembly and assembly. The lower end of the first screw 4 is connected to the rotating rod 15, which extends through the slot and is rotatably connected to the handle 16 located in the slot on the front and rear sides. The handle 16 is in a folded storage state to facilitate manual operation to adjust the position of the baffle 6 in case of motor 9 failure.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes a sliding frame 11 and a spring 12. The bottom of the lifting block 10 is slidably connected to the sliding frame 11. The upper right side of the support frame 2 has two sets of symmetrical slots 121, with two slots in each set. In the initial state, the sliding frame 11 engages with the upper slot 121 to fix the position of the lifting block 10. Two springs 12 are connected between the sliding frame 11 and the inside of the lifting block 10. The bottom right side of the sliding frame 11 is rotatably connected to a handle, which makes it easy for the operator to pull the sliding frame 11.

[0024] When motor 9 malfunctions or there is a power outage, to ensure the normal use of baffle 6, the sliding frame 11 can be pulled to the right. At this time, spring 12 is compressed, and after sliding frame 11 moves to the right, it no longer engages with the upper slot 121. Then, sliding frame 11 can be pushed down, which will drive lifting block 10, motor 9 and second gear 8 to move downward as a whole, so that second gear 8 disengages from first gear 7. Then, release sliding frame 11, spring 12 rebounds and resets, sliding frame 11 automatically moves to the left and re-engages with lower slot 121, thereby fixing the position of sliding frame 11. Next, remove pin 14 and remove protective frame 13, rotate handle 16 downward to unfold for easy operation, and then manually rotate rotating rod 15 through handle 16, thereby driving first screw 4 to rotate, realizing the opening and closing control of baffle 6, so that motor 9 is not required to drive it. When the motor 9 resumes normal operation, fold the handle 16 upwards and reinstall the protective frame 13. Use the pin 14 to fix it in the slot. Then repeat the above operation: pull the sliding frame 11 to the right to disengage it from the slot 121, and then push the lifting block 10 upwards to move the components on it, so that the second gear 8 re-engages with the first gear 7. Release the sliding frame 11 and let the spring 12 drive the sliding frame 11 to move to the left and re-engage with the upper slot 121 to fix the position of the lifting block 10. Then the motor 9 can drive the first screw 4 to rotate normally.

[0025] like Figure 5As shown, it also includes a connecting block 17, a second screw 18, and a locking block 19. The connecting block 17 is welded to the rear side of the lifting block 10. The second screw 18 is rotatably connected to the upper part of the support frame 2 near the connecting block 17. A square locking block 19 is threaded onto the second screw 18. The locking block 19 is tightly against the wall of the support frame 2 and is limited by the support frame 2, allowing only linear movement and preventing rotation. The locking block 19 abuts against the connecting block 17 to prevent the lifting block 10 from sliding. When it is necessary to disengage the first gear 7 from the second gear 8, it is necessary to... To adjust the height of the lifting block 10, first rotate the second screw 18 to move the locking block 19 to the left so that it no longer blocks the connecting block 17. At this time, the lifting block 10 is in a freely movable state. Push the lifting block 10 downward to adjust the position of the second gear 8 so that it separates from the first gear 7. After use, move the lifting block 10 upward to reset it to the initial height. Reverse the second screw 18 to move the locking block 19 to the right so that it blocks the connecting block 17 again, thereby locking the position of the lifting block 10 and preventing it from sliding down accidentally.

[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
