[0033] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0034] Reference Figures 1 to 4 An integrated multi-contact structure includes an integrated plate 1, a compacting plate 2, an oil cylinder 3 and a pressing block 4. The number of oil cylinders 3 is several and the top of each oil cylinder 3 is connected to the integrated plate 1. The top of each oil cylinder 3 is provided with a plug cavity oil port 34 and a rod cavity oil port 35. All the plug cavity oil ports 34 and the rod cavity oil ports 35 can be connected to the oil circuit system 5 arranged inside the integrated plate 1. The bottom of the oil cylinder 3 extends out of the compacting plate 2 and can move relative to the compacting plate 2. The pressing block 4 is detachably connected to the bottom of the oil cylinder 3.

[0035] The pressing block 4 can realize synchronous movement with the bottom of the oil cylinder 3. The connection between the pressing block 4 and the oil cylinder 3 is preferably bolted. When the oil cylinder 3 is working, the pressing block 4 is located at the bottom of the oil cylinder 3 and will actually squeeze and contact with the sand. In this embodiment, the shape of the pressing block 4 is not specifically limited. Figure 3 , can be circular, refer to Figure 4 , it can also be square, or other required shapes, and can be flexibly selected and set according to actual use requirements;

[0036] Since the pressing block 4 is prone to wear and damage after long-term use, the detachable connection mode allows the pressing block 4 to be replaced after a certain period of use, or the shape of the pressing block 4 can be changed at any time according to actual use requirements.

[0037] After the oil cylinder 3 is started, it can drive the pressing block 4 to move relative to each other to perform compaction operation. Therefore, the oil cylinder 3 and the pressing block 4 can be combined to form a contact structure for compacting the sand mold. Since the number of the above-mentioned combined structures is several, a multi-contact oil cylinder structure can be formed.

[0038] By providing a combined structure of a compacting plate 2 and several oil cylinders 3 in the form of multiple contacts and a pressing block 4, the compacting plate 2 and the pressing block 4 are both capable of realizing compaction operations. When performing compaction operations, the equipment can be selected more flexibly, that is, the compacting plate 2 and the oil cylinder structure with multiple contacts can be used together to complete the compaction action, or the oil cylinder structure with multiple contacts can be used alone to complete the compaction action, or the compacting plate 2 can be used alone to complete the compaction action, or the compacting plate 2 can be used first to perform the compaction action and then the oil cylinder structure with multiple contacts can be used to perform the compaction action to complete double compaction. There is no limit to the various forms of compaction methods.

[0039] By connecting several cylinders 3 to the integrated board 1, and the plug chamber oil ports 34 and rod chamber oil ports 35 on all the cylinders 3 can be connected to the oil circuit system 5 arranged inside the integrated board 1, the integrated board 1 can integrate all the cylinders 3 together, eliminating the complicated oil pipe structure, and at the same time integrating all the oil ports together, the design and arrangement of the oil circuit system 5 are easier, the overall structural form is simpler and more beautiful, and the failure rate is effectively reduced.

[0040] The integrated board 1 is designed to integrate all the cylinders 3, which is convenient for unified control or multi-way control. Under the drive of the external hydraulic station, when the hydraulic oil enters the plug chamber oil port 34, the cylinder retracts, and when the hydraulic oil enters the rod chamber oil port 35, the cylinder extends. By unified control or multi-way control of the plug chamber oil port 34 and the rod chamber oil port 35, the extension and retraction actions of all the cylinders 3 can be controlled.

[0041] As an optional embodiment, the oil circuit system 5 includes a plug chamber oil inlet circuit 51 and a rod chamber oil inlet circuit 52. The plug chamber oil inlet circuit 51 can be connected to the plug chamber oil port 34, and the rod chamber oil inlet circuit 52 can be connected to the rod chamber oil port 35.

[0042] In this embodiment, the number of the plug cavity oil inlet passage 51 is at least one. When the number of the plug cavity oil inlet passage 51 is one, the plug cavity oil inlet passage 51 is connected to all the plug cavity oil ports 34.

[0043] In this embodiment, the number of the rod chamber oil inlet passage 52 is at least one. When the number of the rod chamber oil inlet passage 52 is one, the rod chamber oil inlet passage 52 is connected to all the rod chamber oil ports 35.

[0044] By selecting and setting the specific number and arrangement of the plug cavity oil inlet passages 51 and the specific position of the plug cavity oil port 34 to which each plug cavity oil inlet passage 51 is connected, and by selecting and setting the specific number and arrangement of the rod cavity oil inlet passages 52 and the specific position of the rod cavity oil port 35 to which each rod cavity oil inlet passage 52 is connected, the oil passages of all integrated oil cylinders 3 can have a variety of arrangement methods, that is, unified control of all integrated oil cylinders 3 can be achieved, or multi-channel control of oil cylinders 3 on different oil passages can be achieved, and the oil passages of the oil cylinders 3 can be selected to be connected separately from the outer circle to the inner circle, or the oil passages of all oil cylinders 3 can be connected in a complete serpentine manner, or each oil cylinder 3 in a horizontal row can be connected separately, or each oil cylinder 3 in a vertical row can be connected separately;

[0045] Each of the above-mentioned separate oil circuits can be controlled for oil supply through a control valve or other equipment, so that the oil cylinders 3 at different positions can be selected for compaction operations according to different usage requirements.

[0046] As an optional implementation, a number of cylinders 3 are distributed in an array. The array distribution can make the cylinders 3 more evenly distributed, thereby forming evenly distributed multiple contacts, covering the entire compaction operation area. Through the reasonable arrangement of the oil circuit system 5, various compaction operations can be effectively completed.

[0047] As an optional embodiment, the oil cylinder 3 includes a piston rod 31, a fixing member 32 and a cylinder body 33. The top of the piston rod 31 is connected to the integrated board 1 through the fixing member 32. The plug cavity oil port 34 and the rod cavity oil port 35 are arranged at the top of the piston rod 31. The cylinder body 33 is movably connected to the outside of the piston rod 31 and its bottom extends out of the compacting plate 2. The pressure block 4 is connected to the bottom of the cylinder body 33. After the oil cylinder 3 is started, the cylinder body 33 can move relative to the piston rod 31 to drive the pressure block 4 to move.

[0048] By providing a fixing part 32, the fixing part 32 can install the piston rod 31 on the integrated board 1, so that the piston rod 31 remains relatively still, and then moves through the cylinder body 33 and drives the pressure block 4 to move to realize the compaction operation, and the plug chamber oil port 34 and the rod chamber oil port 35 are directly arranged on the top of the piston rod 31, and are directly connected to the oil circuit system 5 arranged inside the integrated board 1, eliminating the complex oil pipe structure, and the overall structural form is simpler and more beautiful, while effectively reducing the failure rate.

[0049] As an optional embodiment, it further includes a first sealing unit 6, which is disposed on the outside of the compacting plate 2 and is capable of forming a seal between the auxiliary sand box located on the outside of the compacting plate 2 and the compacting plate 2;

[0050] In existing molding machines, the auxiliary sand box is usually located outside the compacting mechanism, and relative movement can occur between the two.

[0051] Since in the subsequent sand-shooting process, the airflow suspended sand-shooting method easily causes sand to enter the fitting gap between the compaction plate 2 and the auxiliary sand box, the setting of the first sealing unit 6 can effectively prevent sand from entering the fitting gap between the compaction plate 2 and the auxiliary sand box, avoid the equipment being stuck by sand, and ensure that the auxiliary sand box can move smoothly relative to the compaction plate 2.

[0052] As an optional embodiment, the first sealing unit 6 includes a first sealing ring 61 and a fixing groove 62. The fixing groove 62 is provided on the outer side wall of the compacting plate 2. The fixing groove 62 is provided in an annular shape. The fixing groove 62 is conducive to the proper placement of the first sealing ring 61.

[0053] The first sealing ring 61 is arranged inside the fixing groove 62 and contacts the auxiliary sand box. The first sealing ring 61 can effectively prevent sand from entering the matching gap between the compaction plate 2 and the auxiliary sand box, avoid the equipment being stuck by sand, and ensure that the auxiliary sand box can move smoothly relative to the compaction plate 2.

[0054] As an optional embodiment, it further includes a second sealing unit 7, which is connected to the compacting plate 2 and can form a seal between the compacting plate 2 and the oil cylinder 3;

[0055] Since the airflow suspended sand shooting method in the subsequent sand shooting process easily causes sand to enter the fitting gap between the compaction plate 2 and the cylinder 3, the second sealing unit 7 is provided to effectively prevent sand from entering the fitting gap between the compaction plate 2 and the cylinder 3, thereby avoiding the equipment being stuck by sand and ensuring the smoothness of the movement of the cylinder 3 relative to the compaction plate 2.

[0056] As an optional implementation, the second sealing unit 7 includes a second sealing ring 71 and a fixed flange 72. The fixed flange 72 is connected to the compaction plate 2. The flange connection has good connection strength and is easy to disassemble and assemble. The second sealing ring 71 is arranged between the fixed flange 72, the compaction plate 2 and the cylinder 3. The second sealing ring 71 can effectively prevent sand from entering the fitting gap between the compaction plate 2 and the cylinder 3, avoid the equipment being stuck by sand, and ensure the smoothness of the movement of the cylinder 3 relative to the compaction plate 2.

[0057] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
