DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0025] See also Figures 1 to 11 A bridge shell casting device for a dump truck comprises a base 1, a gantry bracket 2 for support is fixedly installed on the upper surface of the base 1, a casting component 3 for casting the bridge shell is provided in the middle position inside the gantry bracket 2, a movable plate 5 is provided above the casting component 3, a casting bucket 51 is fixedly installed in the middle of the upper surface of the movable plate 5, a driving motor 21 is fixedly installed on the upper surface of the gantry bracket 2, a screw rod 22 is fixedly installed on the driving end of the driving motor 21, the screw rod 22 is clamped on the moving plate 5 through a threaded fit, the moving plate 5 is used to change the state of the casting component 3, a cooling component 6 for cooling is fixedly installed on the upper surface of the base 1, and matching components 4 are provided on both sides of the casting component 3.

[0026] In actual use, the screw rod 22 is driven to rotate by the driving motor 21, and the movable plate 5 is driven to descend. When the movable plate 5 descends, the casting bucket 51 is connected with the casting component 3. At this time, molten metal can be added to the inside of the casting bucket 51 to make it flow into the casting component 3 to form a bridge shell blank. Because when the high-temperature molten metal flows into the inside of the casting component 3, it takes a long time to cool down, which wastes time and reduces production efficiency. When the casting is completed, the driving motor 21 is controlled to reverse and drive the screw rod 22 to reverse, so that the movable plate 5 rises, and the casting bucket 51 is separated from the casting component 3. As the movable plate 5 continues to rise, At this time, the casting component 3 will be driven to rotate, and the cast bridge shell blank will be rotated downward. At this time, the other side of the casting component 3 will be rotated upward to facilitate continuous casting operations. The cooling component 6 will cool the bridge shell cast below the casting component 3. At this time, with the continuous decline and rise of the movable plate 5, the bridge shell cast below the casting component 3 will be driven by the matching component 4 for automatic demolding, thereby realizing efficient and continuous production. Through this device, the cooling and demolding processes of the bridge shell blank can be carried out simultaneously, which significantly improves production efficiency, reduces manual intervention, reduces production costs, and ensures the quality stability and consistency of the bridge shell blank.

[0027] The casting component 3 includes a central mold 31, and mold covers 32 are provided on the upper and lower sides of the central mold 31. A casting port 321 is fixedly installed in the middle of the upper surface of the mold cover 32. A plurality of evenly distributed guide rods 316 are fixedly installed on the upper and lower sides of the central mold 31. The mold cover 32 is slidably sleeved on the outside of the guide rods 316. A first casting cavity 311 is provided on the upper and lower sides of the central mold 31. A second casting cavity 326 matching the first casting cavity 311 is provided on the side of the mold cover 32 close to the central mold 31. The matching component 4 is used to change the relative position of the mold cover 32 and the central mold 31. The matching component 4 is fixedly installed on the lower surface of the movable plate 5. A central rotating member 312 is rotatably installed on both sides of the central mold 31. A connecting sleeve rod 315 is slidably sleeved on both sides of the central rotating member 312 corresponding to the mold cover 32. The end of the connecting sleeve rod 315 away from the central rotating member 312 is rotatably installed on the corresponding side surface of the mold cover 32.

[0028] When the movable plate 5 descends, the bottom of the casting bucket 51 will enter the interior of the mold cover 32. At this time, molten metal can be poured into the interior of the casting bucket 51 to flow into the interior of the first casting cavity 311 through the mold cover 32. When the casting component 3 is in a vertical state, the mold cover 32 is tightly pressed on the central mold 31 to ensure that the molten metal does not leak out. At this time, the first casting cavity 311 and the second casting cavity 326 form a closed space, and the molten metal is cooled and formed inside. As the movable plate 5 rises and falls, the central rotating part 312 drives the central mold 31 to rotate, and then the central mold 31 drives the mold cover 32 and the guide rod 316 to rotate synchronously. When the movable plate 5 rises, the mold cover 32 will automatically close to prevent the molten metal inside the first casting cavity 311 from overflowing, thereby ensuring the accuracy and safety of the casting process. At the same time, the rotation of the central rotating part 312 makes the later demolding smoother and avoids the problem of metal residue. The mold is damaged, which increases the service life of the mold, further optimizes the production process, and ensures the continuous stability of product quality. After the casting of the first casting cavity 311 above is completed, the movable plate 5 is driven to rise by the driving motor 21. At this time, the casting component 3 is driven to rotate, and the first casting cavity 311 that has not been cast below is rotated to the upper casting position, thereby realizing continuous casting. At the same time, the cast bridge shell blank below will be efficiently cooled down along with the casting component 3 by the cooling system of the cooling component 6 to ensure that it quickly reaches the demolding conditions and is cooled simultaneously during casting, thereby realizing efficient forming and demolding of the bridge shell blank. The simultaneous cooling treatment effectively avoids deformation caused by thermal stress, improves the mechanical properties of the bridge shell blank, ensures the stability of product quality and maximizes production efficiency. As the device continues to work, the bridge shell blank that has been cooled and formed below will be driven by the matching component 4 for automatic demolding, which greatly improves production efficiency.

[0029] The mold cover plate 32 is provided with a first groove body 33 at both sides of the casting port 321, and a second groove body 34 is provided on one side of the first groove body 33. The second casting cavity 326, the second groove body 34, and the first groove body 33 are connected in sequence. A sliding post 341 is provided inside the second groove body 34. A return spring 342 is fixedly connected between the sliding post 341 and the second groove body 34. A second tooth plate 343 is fixedly installed on the upper end of the sliding post 341 near the first groove body 33. The inside of the second groove body 34 A ventilation groove 344 for exhaust is opened at the lower end, and a plurality of evenly distributed exhaust ports 322 are fixedly installed on the side of the mold cover plate 32 away from the central mold 31. The ventilation groove 344 is connected to the corresponding exhaust ports 322. A first tooth plate 331 is fixedly installed on the side of the first trough body 33 away from the second trough body 34. An insertion rod 35 is provided inside the first trough body 33. Two mutually meshing gears 351 are rotatably installed on the bottom end of the insertion rod 35. The insertion rod 35 is fixedly installed on the lower surface of the movable plate 5.

[0030] When the movable plate 5 descends, it will drive the insertion rod 35 into the interior of the first slot body 33. At this time, the two gears 351 are meshed with the first tooth plate 331 and the second tooth plate 343 respectively. As the insertion rod 35 continues to descend, the second tooth plate 343 is driven to rise under the drive of the two gears 351, thereby pushing the sliding column 341 to move upward, and the return spring 342 is compressed accordingly. At this time, the sliding column 341 loses its obstruction to the ventilation groove 344, and the air inside the first casting cavity 311 can be discharged through the ventilation groove 344 and the exhaust port 322 during casting, ensuring that no bubbles are generated during the casting process, thereby improving the density of the molten metal. Solidity, when the movable plate 5 rises, the gear 351 will drive the second tooth plate 343 and the sliding column 341 to descend until the gear 351 is completely disengaged from the first tooth plate 331 and the second tooth plate 343, and the sliding column 341 resumes the blocking of the vent groove 344, ensuring that air cannot enter during the next casting, maintaining the purity of the molten metal and the casting quality, and ensuring that the first casting cavity 311 and the second casting cavity 326 form a stable sealing environment, avoiding the risk of leakage of the molten metal, further improving the safety and reliability of the device, and ensuring the stability and efficiency of the entire casting process, thereby ensuring the molding quality of the bridge housing blank.

[0031] A first ratchet 313 is fixedly installed on the side of the central rotating member 312 away from the central mold 31, and a second ratchet 314 is fixedly installed on the side of the first ratchet 313 away from the central rotating member 312. The second ratchet 314 is rotatably installed inside the gantry bracket 2, and sliding plates 52 are fixedly installed on both sides of the lower surface of the movable plate 5. A movable groove is opened on the sliding plate 52, and a plurality of evenly distributed first ratchet teeth 53 are installed on one side of the inner part of the movable groove. The first ratchet teeth 53 are used to drive the first ratchet 313 to rotate unidirectionally, and a second ratchet for limiting the unidirectional rotation of the second ratchet 314 is fixedly installed inside the gantry bracket 2.

[0032] When the movable plate 5 descends, the first ratchet 53 is driven to descend. At this time, the first ratchet 53 is blocked by the first ratchet wheel 313 and undergoes elastic deformation, and thus will not drive the first ratchet wheel 313 to rotate. When the movable plate 5 rises, the first ratchet 53 returns to its original state, driving the first ratchet wheel 313 to rotate. Because the second ratchet wheel 314 cooperates with the second ratchet tooth inside the gantry bracket 2, it can prevent the first ratchet wheel 313 from being driven to rotate in the opposite direction, so that the casting component 3 can only rotate in one direction, and the stability of the casting component 3 is maintained without loosening or offsetting, thereby ensuring the accuracy and consistency of the entire device during operation, and further improving the stability and reliability of the casting system.

[0033] Slide rods 327 are fixedly installed on both sides of the mold cover plate 32, and the matching component 4 includes an incomplete circular ring 41. A guide component 42 is fixedly installed at the notch of the incomplete circular ring 41. The guide component 42 has a V-shaped part 43 on the side away from the incomplete circular ring 41. The inner sides of the guide component 42 and the V-shaped part 43 are provided with sliding grooves 44 for the sliding of the slide rod 327, and the mold cover plate 32 is rotatably clamped inside the incomplete circular ring 41.

[0034] When the casting component 3 is in a vertical state, the mold cover 32 is restricted by the incomplete ring 41 and fits tightly against the upper and lower surfaces of the center mold 31, ensuring the sealing between the center mold 31 and the mold cover 32 to prevent the leakage of molten metal during the casting process. As the casting component 3 gradually rotates from a vertical state to a horizontal state, the slide bar 327 on the lower mold cover 32 will slide along the lower end of the slide groove 44 into the interior of the slide groove 44, and as the casting component 3 rotates, the slide bar 327 will enter the slide groove 44 corresponding to the V-shaped part 43, and then will be driven by the slide groove 44 to move. 327 will drive the mold cover 32 to separate from the center mold 31. As the casting component 3 continues to rotate, the slide rod 327 will detach from the top of the slide groove 44. At this time, the mold cover 32 is restricted by the incomplete ring 41 again, and fits tightly to the upper and lower surfaces of the center mold 31 to ensure sealing, prevent leakage of molten metal, and ensure the stability and safety of the casting process. Through this sophisticated mechanical design, not only the risk of leakage due to component wear is effectively avoided, but also the service life and maintenance efficiency of the equipment are significantly improved, ensuring stability and reliability in long-term operation, and laying a solid foundation for the production of high-quality bridge housing blanks.

[0035] A sliding door 323 is provided on the middle sliding card of the casting port 321, a flow port 325 is opened at the end of the sliding door 323, a spring telescopic rod 324 is fixedly connected between the sliding door 323 and the casting port 321, and a tilting rod 54 for pushing the sliding door 323 to move is fixedly installed on the lower surface of the moving plate 5.

[0036] When the movable plate 5 descends, the tilting rod 54 will be driven down. At this time, the tilting rod 54 will push the sliding door 323 to move, thereby driving the spring telescopic rod 324 to be stretched, and the flow port 325 enters the interior of the casting port 321 as the sliding door 323 moves. The molten metal can enter the second casting cavity 326 and the first casting cavity 311 through the casting port 321 and the flow port 325. When the movable plate 5 rises, the tilting rod 54 loses the driving force on the sliding door 323. The sliding door 323 is reset under the action of the spring, the spring telescopic rod 324 contracts, and the flow port 325 exits the casting port 321, cutting off the metal flow, ensuring precise control of the casting process, preventing overflow, and improving the quality of the finished product. It can also automatically seal after casting to prevent leakage of molten metal.

[0037] The cooling component 6 includes a first water tank 61, on the upper surface of which a plurality of evenly distributed second water tanks 62 are fixedly installed, and the upper end sliding card of the second water tank 62 is provided with a plurality of evenly distributed first sliding cylinders 63, and above the first sliding cylinder 63 a plurality of evenly distributed cooling fins 64 are fixedly installed, and the interiors of the cooling fins 64, the first sliding cylinder 63, the second water tank 62, and the first water tank 61 are connected in sequence, and a plurality of connecting pipes 65 for water inlet and outlet are fixedly installed on one side of the first water tank 61, and a plurality of evenly distributed nozzles 631 are provided at the upper end of the first sliding cylinder 63, and the nozzles 631 are used to spray water mist, and a fan 11 is fixedly installed in the middle of the base 1, and the fan 11 is located on one side of the cooling component 6, and a plurality of evenly distributed cooling grooves 328 are provided on the side of the mold cover plate 32 away from the central mold 31, and the cooling fins 64 cooperate with the corresponding cooling grooves 328 for cooling.

[0038] When the casting component 3 is in a vertical state, the cooling fin 64 is located inside the cooling groove 328, and the first sliding cylinder 63 is pushed into the second water tank 62. At this time, the nozzle 631 is blocked and the water flow cannot pass through, ensuring the internal pressure stability. When the casting component 3 rotates from a vertical state to a horizontal state, the first sliding cylinder 63 and the cooling fin 64 are driven up by the water pressure, and the nozzle 631 is gradually exposed. The water flow inside the second water tank 62 and the first sliding cylinder 63 will be sprayed out through the nozzle 631 to form water mist. With the action of the fan 11, the mold cover plate 32 that has just been cast can be quickly cooled down. By activating air cooling and water cooling at the same time, the surface temperature of the mold cover plate 32 can be quickly reduced to prevent deformation caused by thermal stress and improve cooling efficiency. Ensure the dimensional accuracy and surface quality of the bridge shell blank and provide reliable guarantee for subsequent processing. Because no casting will be carried out when the casting component 3 is in a horizontal state, the cooling component 6 can quickly cool the environment and pre-cool the bridge shell. When the casting component 3 gradually recovers from a horizontal state to a vertical state, the first sliding cylinder 63 is driven down, and the nozzle 631 is blocked again, the water flow stops spraying, and a mold cover plate 32 above is used to re-cast. At this time, the cooling component 6 will also stop cooling the environment to ensure the temperature during the casting process, prevent local cooling speed from being too fast and causing uneven casting, and ensure that each casting link is carried out in a constant temperature environment, thereby improving the overall casting quality. The cooling component 6 can automatically change its own cooling mode according to the casting state of the casting component 3.

[0039] Working principle: In actual use, the driving motor 21 drives the screw rod 22 to rotate, and the movable plate 5 is driven to descend. When the movable plate 5 descends, the casting bucket 51 is connected with the casting component 3. At this time, molten metal can be added to the inside of the casting bucket 51 to make it flow into the casting component 3 to form a bridge shell blank. Because when the high-temperature molten metal flows into the inside of the casting component 3, it takes a long time to cool down, which wastes time and reduces production efficiency. When the casting is completed, the driving motor 21 is controlled to reverse and drive the screw rod 22 to reverse, so that the movable plate 5 rises, and the casting bucket 51 is separated from the casting component 3. As the movable plate 5 continues Rising, at this time, the casting component 3 will be driven to rotate, and the cast bridge shell blank will be rotated downward. At this time, the other side of the casting component 3 is rotated upward to facilitate continuous casting operations. The cooling component 6 will cool the bridge shell cast below the casting component 3. At this time, as the moving plate 5 continues to descend and rise, the bridge shell cast below the casting component 3 will be driven by the matching component 4 to be automatically demoulded, thereby realizing efficient and continuous production. Through this device, the cooling and demoulding processes of the bridge shell blank can be carried out simultaneously, which significantly improves production efficiency, reduces manual intervention, reduces production costs, and ensures the quality stability and consistency of the bridge shell blank; As the casting component 3 rotates, the cooling component 6 can quickly cool the environment and pre-cool the bridge shell. When the casting component 3 gradually recovers from a horizontal state to a vertical state, the first sliding cylinder 63 is driven down, and the nozzle 631 is blocked again, the water flow stops spraying, and a mold cover plate 32 above resumes casting. At this time, the cooling component 6 will also stop cooling the environment to ensure the temperature during the casting process, prevent local cooling speed from being too fast resulting in uneven casting, and ensure that each casting link is carried out in a constant temperature environment, thereby improving the overall casting quality. The cooling component 6 can automatically change its own cooling mode according to the casting state of the casting component 3.
