Description

Technical Field

[0001] This invention belongs to the field of core shooting machine technology, and specifically relates to an automatic feeding device for core shooting machines. Background Technology

[0002] Core shooters are specialized equipment used in the foundry industry to manufacture sand cores. They come in hot and cold core box types and are suitable for complex mold production. Key manufacturers include companies like Suzhou Mingzhi Technology. Through a simultaneous process of sand shooting, compaction, and heat curing, combined with compressed air (200-260℃), they achieve efficient core making, producing high-precision sand cores widely used in casting fields such as automotive parts. The automatic receiving device is used to receive the finished castings from the core shooter and transfer them away.

[0003] Existing technology CN222492062U discloses a core shooting machine that facilitates core connection, including a base. Support plates are symmetrically bolted to the top of the base. A lower mold base is rotatably connected between the two support plates via a rotating shaft. A heating tube is embedded inside the lower mold base. An upper mold base is located on top of the lower mold base. A servo motor is located on the top of the base. The output end of the servo motor is fixedly mounted on the support plates via a fixing component. A connecting plate is located on the top of the base. A transmission mechanism is located on the top of the connecting plate. A lifting mechanism is located at the bottom of the connecting plate. A top plate is located on the top of the base. A hopper is located on the top of the top plate. A crushing chamber is connected to the bottom of the hopper. Crushing rollers are symmetrically rotatably connected to the inside of the crushing chamber via a rotating shaft. A conveying pump connected to the crushing chamber via a pipe is installed at the bottom of the crushing chamber via a fixing component. The output end of the conveying pump is connected to a conveying pipe, and the other end of the conveying pipe is connected to a conveying head connected to the upper mold base. The castings produced by the core shooting machine fall onto the transmission mechanism for cooling. The transmission mechanism has no related cooling structure and uses natural cooling. This cooling method is not only ineffective but also slow, making it difficult for personnel to handle the castings later. Summary of the Invention

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Reference Figures 1-14 This invention provides an automatic receiving device for a core shooting machine, comprising a receiving bracket 1, a receiving and conveying module 2 mounted on the receiving bracket 1, a protective box 3 mounted on the outside of the receiving and conveying module 2, an air extraction module 4 mounted on the protective box 3, a cooling module 5 mounted on the air extraction module 4, an exhaust cooling module 6 mounted on the cooling module 5, and a cold water supply module 7 mounted on one side of the cooling module 5.

[0021] The material receiving and conveying module 2, protective box 3, air extraction module 4, refrigeration module 5, exhaust cooling module 6 and cold water supply module 7 form a circulating cooling system, which greatly improves the cooling effect and speed of the castings, so that they can be directly handled by personnel later.

[0022] Reference Figure 1 and Figure 2 The receiving and conveying module 2 includes two sets of supports 21 fixed to the receiving bracket 1. A roller 22 is screwed between each set of supports 21. The two rollers 22 are connected by a conveyor belt 23. A motor 24 is fixed to the outside of one of the supports 21. The output end of the motor 24 is fixed to one side of its adjacent roller 22. The side wall of the conveyor belt 23 is in contact with the inner wall of the protective box 3. During operation, the motor 24 pulls the roller 22 to rotate, which in turn makes the conveyor belt 23 rotate. When the casting is unloaded, the casting falls onto the conveyor belt 23. The rotating conveyor belt 23 carries the casting to move, realizing the receiving and transfer of the casting.

[0023] Reference Figure 1 and Figure 2 Several soft belts 31 are fixed to the upper ends of the openings on both sides of the protective box 3. The side walls of two adjacent soft belts 31 are in contact, and one side of the two outermost soft belts 31 is in contact with the inner surface of the protective box 3. The lower end of the soft belt 31 leaves a gap with the upper end of the outer surface of the conveyor belt 23. With the installation of the soft belts 31, the soft belts 31, the protective box 3 and the conveyor belt 23 form a sealed space, which can prevent waste from being blown out during the cooling process, ensure the cleanliness of the surrounding environment, and at the same time not affect the movement of the castings in the protective box 3.

[0024] Reference Figure 1 , Figure 2 and Figure 3 The extraction module 4 includes a concave tube 41 fixed to the inner opening of the protective box 3. Several extraction nozzles 42 are connected to the inner side of the concave tube 41. An A connecting pipe 43 is connected to the center of the upper end of the concave tube 41. The A connecting pipe 43 has an L-shaped structure. A B connecting pipe 45 is installed between two A connecting pipes 43. The A connecting pipe 43 and the B connecting pipe 45 are connected to an A temporary storage box 44. One side of the A temporary storage box 44 has a cover plate for handling waste stored in the A temporary storage box 44. The A temporary storage box 44 is used to store waste. The two sides of the B connecting pipe 45 are fixed to... A filter 46, one side of which is located in A temporary storage box 44, B connecting pipe 45 is connected to high pressure fan 47 in the middle, and the other side of high pressure fan 47 is connected to C connecting pipe 48. When cooling the casting, high pressure fan 47 draws hot air containing waste material from the protective box 3 into the refrigeration module 5 for refrigeration, so as to cool the casting later. Before the hot air is drawn into B connecting pipe 45, the waste material is first stripped off by A filter 46. The stripped waste material falls into A temporary storage box 44 for storage under its own weight.

[0025] Reference Figures 5-14 The refrigeration module 5 includes a tank 51. The lower end of one side of the tank 51 is connected to a connector A 53, which is connected to a connecting pipe C 48. The upper end of the other side of the tank 51 is connected to a connector B 54. Both sides of the tank 51 are fixed to a sealing cover 55 by screws. The vertical sides of the sealing cover 55 on the left side are connected to connectors C 56 and D 57 respectively. A barrier plate 58 located between connectors C 56 and D 57 is fixed inside the sealing cover 55. Several aluminum tubes 59 are installed inside the tank 51, and both sides of the aluminum tubes 59 are connected to the sealing cover 55. Several equally spaced bending plates are fixed inside the tank 51. During operation, the drawn-in gas is transferred from connector A 53 to tank 51 and comes into contact with the outer surface of aluminum tube 59, and then is discharged through connector B 54; cold water flows in through connector C 56 and then flows into aluminum tube 59, comes into contact with the inner surface of aluminum tube 59 and cools the hot gas, thereby achieving the purpose of cooling the casting.

[0026] The delay unit is used to extend the cooling time of hot gas. The delay unit includes a movable disc 510 whose outer surface contacts the inner surface of the tank 51. The movable disc 510 is located near the D connector 57. The movable disc 510 moves along the axial direction of the aluminum tube 59. Several constraint ports are reserved on the movable disc 510 for movable connection with the aluminum tube 59. A B-shaped helical beryllium copper wire is installed between the movable disc 510 and the tank 51 to compress the movable disc 510 to move inside the tank 51. The B-shaped helical beryllium copper wire pulls the movable disc 510 to the extreme position near the A connector 53. A cover plate 511 is installed inside the tank 51 to seal the B connector 54. A pressure-reducing unit is installed between the cover plate 511 and the variable disk 510. The pressure-reducing unit is used to control the disassembly and connection of the cover plate 511 and the variable disk 510, thereby achieving the purpose of intermittent exhaust of the B connector 54 and enhancing the cooling function. The outer cover 512 is fixed to the tank body 51 via a screw. The cover plate 511 is movably installed in the outer cover 512. The B connector 54 is installed on the outer cover 512 to facilitate the assembly of the cover plate 511.

[0027] The pressure reduction unit includes an A-shaped beryllium copper wire 513 installed between the outer cover 512 and the cover plate 511. In the initial state, with the cooperation of the A-shaped beryllium copper wire 513, the cover plate 511 is pulled towards the side farther from the variable disk 510. The bottom of the cover plate 511 is fixedly connected to a wedge-shaped connecting platform 514. A movable stage 515 is movably mounted on the movable disk 510. A C-shaped helical beryllium copper wire is installed between the movable stage 515 and the movable disk 510. In the initial state, the movable stage 515 is pressed to move towards the side close to the cover plate 511 under the cooperation of the C-shaped helical beryllium copper wire. The movable stage 515 and the side close to the cover plate 511 are fixedly connected to the pulling stage 516, which cooperates with the connecting stage 514. The cross surface of the pulling stage 516 is wedge-shaped. In the initial state, with the cooperation of the C-shaped helical beryllium copper wire, the moving platform 515 is pressed to move towards the side closer to the cover plate 511, so that the vertical surface of the pulling platform 516 contacts the vertical surface of the connecting platform 514, and the moving disk 510 moves towards the side farther from the A connector 53, the connecting platform 514 and the cover plate 511 are pulled together by the pulling platform 516. The tank body 51 is fixed to the side of the connector 54 near the B joint, and the moving platform 515 is fixed to the side of the long strip 517 near the long strip 517, and the pressing platform 52 that cooperates with the long strip 517 is fixed to the side of the moving platform 515 near the long strip 517. The sides of the long strip 517 and the pressing platform 52 that are close to each other are wedge-shaped.

[0028] The radius of connector B 54 is larger than the radius of connector A 53.

[0029] In the initial state, with the assistance of the B spiral beryllium copper wire, the moving disk 510 is pulled to the extreme position close to the A connector 53, and then the moving disk 510 is positioned on the side of the B connector 54 close to the A connector 53. During operation, hot gas flows into tank 51 through connector A 53. Because the variable plate 510 blocks connector B 54, the gas cannot be discharged through connector B 54. As the pressure of the gas in tank 51 gradually increases, the variable plate 510 is forced to move to the side farther away from connector A 53 under the cooperation of the air pressure.

[0030] When the rotating disc 510 moves to the side of B connector 54 that is farther from A connector 53, the cover plate 511 blocks B connector 54, thereby preventing the hot air inside the tank 51 from being discharged through B connector 54. When the moving plate 510 moves to its extreme position furthest from connector A 53, the inclined wall of the pressure table 52 and the inclined wall of the strip 517 disintegrate. The pressure table 52 then presses the moving plate 515 to its extreme position furthest from the cover plate 511 until the connecting table 514 and the pulling table 516 separate. At this point, with the assistance of the spiral beryllium copper wire 513, the cover plate 511 is rapidly pulled to its extreme position furthest from the moving plate 510, thus releasing the seal of the cover plate 511 on connector B 54, allowing the gas in the tank 51 to escape through connector B 54. This is achieved with the assistance of the spiral beryllium copper wire. Under these conditions, the moving plate 510 is pulled and moved towards the side closer to connector A 53 until the moving plate 510 moves to the side of connector B 54 close to connector A 53. At this moment, the inclined wall of the connecting platform 514 contacts the inclined wall of the pulling platform 516, and then the moving platform 515 is pressed towards the side farther from the cover plate 511. After the moving plate 510 moves to the extreme position of the side closer to connector A 53, the moving platform 515 is pressed towards the side closer to the cover plate 511 with the cooperation of the C spiral beryllium copper wire, and then the vertical surface of the connecting platform 514 contacts the vertical surface of the pulling platform 516, and then moves back to the starting position.

[0031] The radius of connector B 54 is larger than that of connector A 53. This arrangement ensures that the air intake of connector A 53 is less than the air exhaust of connector B 54. After the cover plate 511 is no longer sealing connector B 54, the moving plate 510 can quickly move to the starting position. After the hot air moves into the tank 51 through connector A 53, it cannot be immediately discharged through connector B 54. It can only be discharged through connector B 54 after the pressure of the hot air in the tank 51 is enough to drive the moving plate 510 to the extreme position away from connector A 53. This cycle continues, and the gas is indirectly discharged through connector B 54, prolonging the residence time of the hot air in the tank 51 and ensuring sufficient cooling of the gas.

[0032] The cover plate 511 has a "T" shaped structure. This arrangement allows the moving plate 510 to move towards the side closer to the connector 53 with the assistance of the spiral beryllium copper wire B. Gas can then be discharged through both sides of the cover plate 511, thereby reducing the pressure and allowing the moving plate 510 to successfully move to the starting position, where the connecting platform 514 and the pulling platform 516 make contact with each other vertically. At this moment, a small amount of gas is discharged through both sides of the cover plate 511, and the inflow of gas through the connector 53 is much greater than the outflow, thus ensuring the cooling of the hot gas.

[0033] Reference Figures 10-14 The cooling module 5 also includes a cleaning unit for cleaning the outer surface of the aluminum tube 59. The moving disc 510 drives the cleaning unit to move within the tank 51, thereby cleaning the inner surface of the tank 51.

[0034] The cleaning unit includes a rotating column 518 fixedly connected to the tank body 51, a clamp cylinder 519 connected to the rotating column 518, a rotating disk 510 fixedly connected to one side of the clamp cylinder 519, a number of cleaning disks 520 arranged at equal intervals fixedly connected to the clamp cylinder 519, a number of through ports 521 reserved on the cleaning disks 520 to cooperate with the aluminum tubes 59, the outer peripheral wall of the cleaning disks 520 contacting the inner surface of the tank body 51, and a number of connection ports 522 reserved on the cleaning disks 520. A cleaning ring 523 is screwed into the through-hole 521. The cleaning ring 523 is clamped to the outer circumference of the aluminum tube 59. A traction part for pulling the cleaning ring 523 to rotate is installed on the cleaning disc 520.

[0035] The traction unit includes a rotating disc 524 screwed into the cleaning disc 520. The rotating disc 524 is clamped onto the rotating column 518. The rotating column 518 has a pre-drilled thread 525. A rotating rod 526 that cooperates with the thread 525 is fixedly connected to the center of the rotating disc 524. Several teeth are reserved on the outer circumferential surface of the rotating disk 524. A biting block 527 that meshes with the teeth on the rotating disk 524 is installed on the cleaning ring 523 near the rotating disk 524. The cleaning rings 523 are connected by a chain.

[0036] During operation, hot gas flows into the tank 51 through connector A 53, passes through the connection port 522 and fills the tank 51. Then, under the pressure of the gas, it drives the rotating disc 510 to move, which in turn pulls the hoop 519 to move on the rotating column 518. When the rotating disc 510 pulls the cleaning disc 520 to move on the inner surface of the tank 51, the rotating rod 526, with the cooperation of the thread 525, pulls the rotating disc 524 to rotate in the cleaning disc 520. The cleaning ring 523 close to the rotating disc 524 is pulled to rotate by the A engagement block 527. Then, the cleaning ring 523 on the cleaning disc 520 is pulled to rotate together by the chain. Then, when the rotating disc 510 pulls the cleaning disc 520 to move in the tank 51, the cleaning ring 523 moves with the cleaning disc 520 to clean the outer surface of the aluminum tube 59. The cleaning ring 523 rotates around the outer surface of the aluminum tube 59, thereby enhancing the cleaning function.

[0037] The cleaning ring 523 is attached to a sprocket that works in conjunction with the chain, thereby allowing the cleaning ring 523 to rotate together to enhance the cleaning function.

[0038] A cleaning disc 528 for cleaning the aluminum tube 59 is fixedly connected to the cleaning ring 523. The cleaning disc 528 cleans the aluminum tube 59, thereby enhancing the cleaning function on the outer surface of the aluminum tube 59. The cleaning disc 528 can remove the waste material attached to the outer surface of the aluminum tube 59, allowing it to move away from the aluminum tube 59, and preventing waste material from accumulating between the cleaning ring 523 and the aluminum tube 59, which would damage the outer surface of the aluminum tube 59.

[0039] A movable ring 529 is installed on the outer surface of the cleaning disc 520, and several B-type engagement blocks 530 are installed on the inner surface of the movable ring 529. An engagement opening 531 for engaging with the B-type engagement blocks 530 is reserved on the cleaning ring 523 near the movable ring 529. A lever 532 is fixedly connected to the moving ring 529, and a lever bar 533 is fixedly connected to the lever 532. During operation, the cleaning ring 523 rotates, which in turn pulls the B engagement block 530 to rotate via the engagement port 531. The B engagement block 530 then pulls the rotating ring 529 to rotate. When the rotating ring 529 rotates, it pulls the lever plate 532 and lever bar 533 to rotate on the inner surface of the tank 51, thereby turning over the waste material at the lower end of the tank 51. This allows the waste material that has fallen to the lower end of the tank 51 to float up with the gas, so that the waste material can be discharged through the B connector 54 with the airflow.

[0040] Reference Figure 1 , Figure 2 and Figure 4 The exhaust cooling module 6 includes a T-shaped pipe 61 connected to the B connector 54 and a diversion pipe 64 fixed to the two side walls of the protective box 3. The upper ends of the T-shaped pipe 61 are connected to a B storage box 62. The B storage box 62 and the diversion pipe 64 are connected via a D connecting pipe 63. Several nozzles 65 are connected to the diversion pipe 64. A B filter 66 is fixed to one side of the B storage box 62 via the D connecting pipe 63. One side of the B filter 66 is inside the B storage box 62. The pore size of the B filter 66 is smaller than that of the A filter 46. The B filter 66 is used to detach the exhaust heat from the cooling module. The waste flowing out of the refrigeration module 5 is temporarily stored in the B storage box 62, which is used to temporarily store the waste stripped from the B filter screen 66. The B storage box 62 has a cover on one side to handle the waste stored in the B storage box 62. When the cold air flows out from the refrigeration module 5, it flows to the B filter screen 66 through the T-shaped pipe 61. The B filter screen 66 strips the waste from the cold air to ensure the cleanliness of the incoming cold air. Then the cold air flows to the diversion pipe 64 through the D connecting pipe 63. The diversion pipe 64 then discharges the cold air through the nozzle 65, thereby ensuring the cooling function of the protective box 3 and achieving the purpose of rapidly cooling the casting.

[0041] Reference Figure 1 The chilled water supply module 7 includes a chiller unit 71 fixed to the side of the protective box 3. The drain end and water inlet end of the chiller unit 71 are connected to the C connector 56 and the D connector 57 respectively via two E connector pipes 72. The chiller unit 71 sends chilled water into the refrigeration module 5 through the E connector pipe 72 and the C connector 56. After the refrigeration module 5 cools the hot air, it returns to the chiller unit 71 through the D connector 57 and the E connector pipe 72 for cooling. This realizes the recycling of chilled water and ensures the refrigeration module 5's function of cooling the gas.
