Description

Technical Field

[0001] This utility model relates to the field of impregnation technology for die castings, and in particular to an impregnation device for die castings. Background Technology

[0002] In the field of die casting production and processing, in order to improve the sealing performance and structural stability of die castings, it is usually necessary to use an impregnation process to seal the tiny pores inside the die castings. The die casting impregnation device is the core equipment to realize this process.

[0003] In existing die-casting impregnation devices, the core structure generally consists of an impregnation cylinder and a cover plate rotatably connected to the top of the cylinder. The impregnation cylinder can hold impregnating liquid to meet the impregnation operation requirements. In actual operation, the operator first needs to neatly place multiple die-castings to be impregnated on a circular cross-section pallet. Then, using the lifting hook provided with the device, the pallet supporting the die-castings is slowly lowered into the impregnation cylinder from top to bottom until the pallet is completely submerged in the impregnating liquid, ensuring that the die-castings fully contact the impregnating liquid and complete the impregnation process.

[0004] However, the current die-casting impregnation device still has obvious defects and shortcomings in practical applications, mainly in the following two aspects: First, during the process of the lifting hook driving the pallet to be placed into the impregnation cylinder from top to bottom, the existing lifting hook structure design lacks an effective stable limiting mechanism, which causes it to shake when bearing the weight of the pallet and the die-casting, thus causing the pallet to shake synchronously. This shaking can cause the die-cast parts on the pallet to shift, collide, or even fall, affecting the stability of the impregnation operation and the integrity of the die-cast parts. Furthermore, operators must continuously manually support the pallet to maintain its stability, a process requiring sustained effort and significant labor intensity. Secondly, once the pallet is fully immersed in the impregnation liquid in the impregnation cylinder, the lifting hook must be separated from the pallet to prevent interference with subsequent impregnation processes. In existing devices, this separation operation also relies on manual movement of the lifting hook. This manual movement requires overcoming the weight of the hook itself and potential frictional resistance, making it laborious. Moreover, the precision of manual operation is difficult to control, easily leading to incomplete separation of the hook from the pallet or collisions during separation, thus affecting the stability and efficiency of the impregnation process. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a die-casting impregnation device, which solves the technical problems of existing die-casting impregnation devices in terms of the stability of pallet placement and the separation operation of lifting hooks, resulting in high labor intensity and low work efficiency for operators, making it difficult to meet the technical requirements of efficient and stable impregnation processes in modern die-casting production.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An impregnation device for die-castings includes an impregnation cylinder, a cover plate rotatably connected to the top of the impregnation cylinder, and a lifting hook for driving a support plate for the die-casting to be inserted into the impregnation cylinder from top to bottom. A connecting structure is attached to the bottom of the lifting hook, and the bottom of the connecting structure is detachably connected to the top of the support plate. An electrically operated telescopic rod is provided on the outer wall of the impregnation cylinder, which can move closer to or further away from the cylinder. The telescopic end of the electric telescopic rod faces upward and is connected to two clamping plates that can move closer to or further away from each other. During the process of the support plate being inserted into the impregnation cylinder from top to bottom, when the two clamping plates move closer to each other and their inner walls contact and clamp the connecting structure, the two clamping plates stabilize the connecting structure and prevent the support plate from shaking. When the support plate is completely immersed in the impregnation cylinder, and the two clamping plates move further away from each other and their outer walls contact the connecting structure, the two clamping plates push the connecting structure away from the support plate.

[0007] Working principle: In actual operation, the operator first needs to neatly place multiple die-cast parts to be impregnated on a pallet with a circular cross-section, connect the connecting structure to the top of the pallet, and then install the connecting structure on the lifting hook. Subsequently, through the lifting hook provided with the device, the pallet supporting the die-cast parts is slowly lowered into the impregnation cylinder from top to bottom. During this process, the two clamping plates move towards the impregnation cylinder, and the electric telescopic rod is activated to adjust the height of the two clamping plates. Then, the two clamping plates are brought closer together and their inner walls contact the connecting structure, clamping the connecting structure. The two clamping plates can stabilize the connecting structure and prevent the pallet from shaking. The electric telescopic rod continues to retract to cooperate with the descent of the pallet. When the pallet is completely submerged in the impregnation liquid, the electric telescopic rod is activated again to adjust the height of the two clamping plates, so that the two clamping plates are moved away from each other and their outer walls contact the connecting structure, pushing the connecting structure away from the pallet.

[0008] Beneficial effects: 1. The device utilizes an adjustable-position and height electric telescopic rod and clamping plates installed on the outer wall of the impregnation cylinder. During the process of the lifting hook lowering the pallet into the impregnation cylinder, the two clamping plates can be controlled to approach the impregnation cylinder and adjusted to a suitable height. Subsequently, the two clamping plates are brought closer together and clamped to the connecting structure via the inner wall. The stabilizing and limiting effect of the clamping plates on the connecting structure effectively counteracts the impact of the lifting hook's own swaying on the pallet, preventing displacement and collision of the pallet due to hook swaying. This completely eliminates the need for manual pallet support by operators, reducing operator workload and preventing displacement, falling, or damage to the die-cast parts due to pallet swaying, thus ensuring the integrity of the die-cast parts and the stability of the impregnation operation. Simultaneously, the electric telescopic rod retracts synchronously with the pallet's descent, ensuring continuous and effective clamping stability and further improving the smoothness of the pallet placement process.

[0009] 2. Once the pallet is completely submerged in the leachate within the impregnation tank, there is no need for manual movement of the lifting hooks. Simply adjust the height of the clamping plates using the electric telescopic rod to move the two clamping plates apart. The contact thrust between the outer walls of the clamping plates and the connecting structure will then push the connecting structure away from the pallet. This entire process is automated by the mechanical structure, eliminating the need for manual force from the weight of the hooks and frictional resistance. This significantly reduces operational difficulty and labor intensity, and avoids incomplete separation or collisions with the pallet caused by insufficient precision during manual operation, ensuring the continuity and stability of the impregnation process.

Detailed Implementation

[0012] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0013] Example: This utility model discloses a die-casting impregnation device, such as... Figures 1-3As shown, the core components include an impregnation cylinder 1, a cover plate 11, a support plate 12, a lifting hook 13, a connecting structure, an electric telescopic rod 2, and a clamping plate 3. The cover plate 11 is rotatably connected to the top of the impregnation cylinder 1 via a hinge, allowing the cylinder to be opened and closed. The support plate 12 has a circular cross-section and is used to support the die-casting part to be impregnated. The lifting hook 13 is connected to an external lifting drive mechanism (such as a cylinder, not shown in the figure), which can move the support plate 12 vertically up and down, thereby allowing the support plate 12 to be placed into or removed from the impregnation cylinder 1. The connecting structure is located between the lifting hook 13 and the support plate 12, enabling a detachable connection between the two. The electric telescopic rod 2 cooperates with the clamping plate 3 to respectively stabilize and limit the support plate 12 during its descent and to separate the connecting structure from the support plate 12. The electric telescopic rod 2 can be an electric push rod, and its stroke and thrust can be adapted according to the weight of the die-casting part and the dimensions of the connecting structure.

[0014] The circular plate 4 is a horizontally arranged circular plate structure. A ring 41 is welded and fixed at the center of its top. The inner diameter of the ring 41 is adapted to the size of the hook of the lifting hook 13. The hook of the lifting hook 13 can be directly hung in the ring 41, realizing the quick connection between the lifting hook 13 and the circular plate 4. At the same time, three connecting blocks 42 are welded and fixed at the bottom of the circular plate 4. The three connecting blocks 42 are evenly distributed around the central axis of the circular plate 4 (the included angle between adjacent connecting blocks 42 is 120°), and the connecting blocks 42 extend outward along the radial direction of the circular plate 4. Each connecting block 42 has a bolt hole at the end away from the circular plate 4 for connection with the connecting parts.

[0015] The mounting block 5 has a cuboid structure, and its top has a through hole corresponding to the bolt hole at the end of the connecting block 42. By passing the bolt through the through hole and the bolt hole of the connecting block 42, the mounting block 5 and the connecting block 42 can be detachably connected, which is convenient for later maintenance or replacement of the connecting parts. During the process of the tray 12 being placed into the impregnation cylinder 1 from top to bottom, when the two clamping plates 3 approach each other and their inner walls contact the outer wall of the mounting block 5 and clamp the mounting block 5, the two clamping plates (3) are used to stabilize the connection structure and prevent the tray (12) from shaking.

[0016] A first groove 51 is provided on one side of the lower part of the mounting block 5. The first groove 51 is circular and extends through the mounting block 5 along the width direction of the mounting block 5 (perpendicular to the extension direction of the connecting block 42). A first limiting hole 52 is provided on the other side of the lower part of the mounting block 5. The first limiting hole 52 is also circular and coaxially connected with the first groove 51. Its diameter is smaller than the groove opening diameter of the first groove 51 (the difference is adapted to the thickness of the first limiting block 54).

[0017] The first irregular hook plate 53 includes an integrally formed first horizontal moving part 531, a first vertical connecting part 532, and a first horizontal connecting part 533: the first horizontal moving part 531 is in the shape of a circular rod, the outer diameter of which is adapted to the diameter of the first limiting hole 52, and can slide through the first limiting hole 52; the first vertical connecting part 532 is in the shape of a vertical plate and is vertically welded to the bottom surface of the first horizontal moving part 531; the first horizontal connecting part 533 is in the shape of a horizontal plate and is vertically welded to the bottom end of the first vertical connecting part 532, and is parallel to the first horizontal moving part 531 (the two are located on the upper and lower sides of the first vertical connecting part 532 respectively, and their extension directions are consistent).

[0018] A first limiting block 54 is welded and fixed to the end face of the first horizontal moving part 531 away from the first vertical connecting part 532. The first limiting block 54 is circular and its outer diameter is adapted to the groove diameter of the first sliding groove 51, so that it can slide horizontally in the first sliding groove 51. Since the outer diameter of the first limiting block 54 is larger than the diameter of the first limiting hole 52, it can prevent the first irregular hook plate 53 from falling off the mounting block 5.

[0019] The first horizontal moving part 531 has a second sliding groove 55 on its side. The second sliding groove 55 is circular and extends along the width direction of the mounting block 5. The first limiting block 54 has a second limiting hole 56. The second limiting hole 56 is circular and coaxially connected with the second sliding groove 55. Its hole diameter is smaller than the groove diameter of the second sliding groove 55 (the difference is adapted to the thickness of the second limiting block 58).

[0020] The structure of the second irregular hook plate 57 is symmetrical to that of the first irregular hook plate 53, including an integrally formed second horizontal moving part 571, a second vertical connecting part 572, and a second horizontal connecting part 573: the second horizontal moving part 571 is in the shape of a circular rod, the outer diameter of which is adapted to the diameter of the second limiting hole 56, and can slide through the second limiting hole 56; the second vertical connecting part 572 is vertically welded to the bottom surface of the second horizontal moving part 571; the second horizontal connecting part 573 is vertically welded to the bottom end of the second vertical connecting part 572 and is parallel to the second horizontal moving part 571.

[0021] A second limiting block 58 is welded and fixed to the end face of the second horizontal moving part 571 away from the second vertical connecting part 572. The second limiting block 58 is in the shape of a circular block, and its outer diameter is adapted to the groove diameter of the second sliding groove 55. It can slide horizontally in the second sliding groove 55, while preventing the second irregular hook plate 57 from falling off the first irregular hook plate 53.

[0022] Three sets of fasteners are welded and fixed to the outer side of the top of the tray 12. The three sets of fasteners correspond one-to-one with the three connecting parts and are evenly distributed around the central axis of the tray 12. Each set of fasteners includes two semi-annular hook blocks 6, which are symmetrically arranged. Their inner diameters are adapted to the outer diameters of the first horizontal connecting part 533 and the second horizontal connecting part 573, respectively. The first horizontal connecting part 533 can be hung in the annular groove of one of the semi-annular hook blocks 6, and the second horizontal connecting part 573 can be hung in the annular groove of the other semi-annular hook block 6, so as to realize the detachable connection between the connecting parts and the tray 12. By sliding and adjusting the position of the first irregular hook plate 53 and the second irregular hook plate 57, the fixing requirements of trays 12 of different sizes can be adapted, improving the versatility of the device. After the tray 12 is fully immersed in the impregnation cylinder 1, the two clamping plates 3 move away from each other and their outer walls come into contact with the inner surfaces of the first vertical connecting part 532 and the second vertical connecting part 572. The two clamping plates 3 push the first irregular hook plate 53 to slide outward along the first limiting hole 52 and the second irregular hook plate 57 to slide outward along the second limiting hole 56, so that the first horizontal connecting part 533 and the second horizontal connecting part 573 are respectively disengaged from the semi-annular hook block 6, thus completing the separation of the connecting structure from the tray 12.

[0023] Three first support blocks 7 are welded and fixed to the outer wall of the impregnation cylinder 1. The three first support blocks 7 are evenly distributed around the central axis of the impregnation cylinder 1 (corresponding to the positions of the three sets of fixing parts) and are located at the same horizontal height. A first limiting groove 71 is opened on the top surface of each first support block 7. The first limiting groove 71 is rectangular and extends radially along the impregnation cylinder 1 (towards or away from the center of the impregnation cylinder 1). A first motor 72 is fixed to the outer wall of the first support block 7 (the side away from the impregnation cylinder 1) by bolts. The output end of the first motor 72 is connected to a first drive shaft 73 through a coupling. The first drive shaft 73 is set along the extension direction of the first limiting groove 71, and its end away from the first motor 72 is rotatably connected to the inner wall of the first limiting groove 71 (the side close to the impregnation cylinder 1) through a bearing.

[0024] The first drive shaft 73 has a threaded section within the first limiting groove 71, and a movable block 74 is threaded onto its outer circumference. The movable block 74 is rectangular and its outer wall is tightly fitted with the inner wall of the first limiting groove 71 (without obvious gaps). It can move along the extension direction of the first limiting groove 71 under the drive of the first drive shaft 73. Three electric telescopic rods 2 are provided. The bottom of each electric telescopic rod 2 is fixed to the top surface of the corresponding movable block 74 by bolts, and the telescopic end of the electric telescopic rod 2 is set upwards. The height of the clamping plate 3 can be adjusted by telescopic movement.

[0025] Each electric telescopic rod 2 has a second support block 8 fixed to its top telescopic end by bolts. The second support block 8 is a cuboid block with a second limiting groove 81 on its side facing the impregnation cylinder 1. The second limiting groove 81 is a cuboid groove that extends horizontally (perpendicular to the telescopic direction of the electric telescopic rod 2). A second motor 82 is fixed to the outer wall of the second support block 8 by bolts. The output end of the second motor 82 is connected to a second drive shaft 83 through a coupling. The second drive shaft 83 is set along the extension direction of the second limiting groove 81, and its end away from the second motor 82 is rotatably connected to the inner wall of the second limiting groove 81 through a bearing.

[0026] The second drive shaft 83 located in the second limiting groove 81 consists of two threaded rod segments with opposite helical directions (the pitch and outer diameter of the two threaded rod segments are the same). The two clamping plates 3 are threadedly connected to these two threaded rod segments respectively. The clamping plates 3 are rectangular plates, and their outer walls are tightly fitted with the inner walls of the second limiting groove 81 (without obvious gaps). The ends of the two clamping plates 3 (the ends closer to the impregnation cylinder 1) extend out of the second limiting groove 81 for contact with the connecting structure. When the second motor 82 drives the second drive shaft 83 to rotate forward, the two reverse threaded rod segments can drive the two clamping plates 3 to move closer to each other. When the second motor 82 rotates in reverse, it can drive the two clamping plates 3 to move away from each other, realizing the opening and closing action of the clamping plates 3.

[0027] Working principle: Pallet 12 Assembly Stage: 1. The operator opens the cover plate 11 at the top of the impregnation cylinder 1 and neatly places the die casting to be impregnated on the top surface of the pallet 12; 2. Adjust the position of the first irregular hook plate 53 and the second irregular hook plate 57 in each connector: slide the first limiting block 54 along the first slide groove 51 to move the first horizontal connecting part 533 to the top of the corresponding semi-circular hook block 6; slide the second limiting block 58 along the second slide groove 55 to move the second horizontal connecting part 573 to the top of another semi-circular hook block 6; then move the circular plate 4 downward so that the first horizontal connecting part 533 and the second horizontal connecting part 573 are respectively hung in the two semi-circular hook blocks 6, thus completing the connection between the connecting structure and the support plate 12. 3. Control the external lifting drive mechanism so that the hook of the lifting hook 13 is hooked in the ring 41 at the top of the circular plate 4, thus completing the connection between the lifting hook 13 and the connecting structure.

[0028] The descent and stabilization phase of tray 12: 1. Start the external lifting drive mechanism to drive the lifting hook 13, connecting structure and support plate 12 (including die casting) to slowly descend and gradually approach the top opening of the impregnation cylinder 1; 2. Synchronously start the first motor 72: The first motor 72 drives the first transmission shaft 73 to rotate, which drives the moving block 74 to move along the first limiting groove 71 toward the impregnation cylinder 1 until the position of the clamping plate 3 corresponds to the height of the connecting structure (circular plate 4 or connecting block 42); 3. Start the electric telescopic rod 2: The telescopic end of the electric telescopic rod 2 extends or retracts, and the height of the second support block 8 and the clamping plate 3 is adjusted so that the inner wall of the clamping plate 3 is aligned with the outer wall of the mounting block 5. 4. Start the second motor 82: The second motor 82 rotates forward, driving the second transmission shaft 83 to rotate, causing the two clamping plates 3 to move closer to each other until the inner wall of the clamping plate 3 is in close contact with the outer wall of the mounting block 5 and clamps the mounting block 5. 5. Continue to control the lifting hook 13 to descend, while the electric telescopic rod 2 retracts synchronously (the retraction speed is consistent with the descent speed of the lifting hook 13). Through the limiting effect of the clamping plate 3 on the mounting block 5, the pallet 12 is prevented from shaking with the lifting hook 13, ensuring that the pallet 12 is stably placed into the impregnation cylinder 1.

[0029] Connection structure separation stage: 1. Once the pallet 12 is completely submerged in the impregnation liquid in the impregnation cylinder 1, stop the descent of the lifting hook 13; 2. Start the electric telescopic rod 2: Adjust the height of the clamping plate 3 so that the outer wall of the clamping plate 3 is aligned with the first irregular hook plate 53 and the second irregular hook plate 57; 3. Start the second motor 82: The second motor 82 reverses and drives the second transmission shaft 83 to rotate, causing the two clamping plates 3 to move away from each other until the outer wall of the clamping plate 3 is in close contact with the inner side of the first vertical connecting part 532 and the second vertical connecting part 572 and applies a pushing force. 4. As the clamping plates 3 continue to move away from each other, the thrust drives the first irregular hook plate 53 to slide outward along the first limiting hole 52 and the second irregular hook plate 57 to slide outward along the second limiting hole 56, so that the first horizontal connecting part 533 and the second horizontal connecting part 573 respectively disengage from the semi-circular hook block 6, completing the separation of the connecting structure from the support plate 12. 5. Start the first motor 72, which drives the moving block 74 and the electric telescopic rod 2 away from the impregnation cylinder 1. At the same time, control the lifting hook 13 to drive the connecting structure to rise and move out of the impregnation cylinder 1. Close the cover plate 11, and leave the support plate 12 and the die-casting parts in the impregnation cylinder 1 for impregnation operation.
