Description

Technical Field

[0001] The present invention relates to the technical field of casting equipment, and in particular to a casting mould vibrating and compacting mechanism and an intelligent casting island. Background Art

[0002] Vibration compaction of casting molds is an important operation step in the casting process to improve the density of the mold. It makes the casting material inside the sand mold or sand core more compact through mechanical vibration or manual operation, thereby ensuring the surface of the casting is smooth, the dimensional accuracy is improved and the occurrence of defects is reduced.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0041] Please refer to 1-8, a casting mold vibrating and compacting mechanism includes a conveying frame 1, a lifting device 11 and a vibrating device 12, a conveying vehicle 2 is arranged on the conveying frame 1, a sand box 21 is arranged on the conveying vehicle 2, fixed pipes 3 are fixedly arranged on both sides of the conveying vehicle 2, a sliding pipe 4 is rotatably and slidably arranged on the fixed pipe 3, a transverse pipe 5 is fixedly arranged on the sliding pipe 4, a reciprocating seat 6 is slidably arranged on the transverse pipe 5, a reciprocating seat 6 is rotatably arranged on the reciprocating seat 6, a reel 61 is rotatably arranged on the reciprocating seat 6, a volute spring is arranged between the reel 61 and the reciprocating seat 6, and a second connecting rod 61 is fixedly arranged on the reciprocating seat 6. One end of the connecting rope 62 and the other end of the second connecting rope 62 are fixedly provided with a hook 63, and the second connecting rope 62 is wound around the reel 61; it also includes a dehooking component, which is used to disengage the hook 63 from the model when the hook 63 is retracted; an adjustment component, which is used to adjust the height of the model and the rotation of the cross tube 5. When the model is fixed, the hook 63 is pulled, and the reel 61 rotates to loosen the second connecting rope 62, so that the hook 63 hangs the model, and in this process, the hooks 63 located on both sides of the sand box 21 can be used to adjust the height of the model and the rotation of the cross tube 5. According to the actual elongation of different lengths, it is suitable for models of various specifications. After the hook 63 hangs the model, the hook 63 hangs the model and moves down into the sand box 21 through the sliding of the reciprocating seat 6. Then, the sand box 21 is moved up and separated from the conveyor 2 through the jacking device 11. In this process, the sliding tube 4 and the sand box 21 are moved up at the same time to ensure that the model is located in the sand box 21. Then, the sand is added through the sand adding device and the vibration device 12 and vibrated and compacted during the sand adding process. In this process, the model does not contact the sand box 21 and is not affected by the sand box 21. 1 The influence of vibration ensures the stability of the model. After the added molding sand buries the bottom of the model and the molding sand is vibrated and compacted, the hook assembly is used to separate the hanger from the model. At this time, the bottom of the model is buried by the molding sand. In the subsequent process of adding sand and vibrating and compacting, the stability of the model is ensured, the quality of casting is improved, and in this process, there is no need to stop the operation of adding sand and vibrating and compacting, which improves production efficiency. After unhooking, the horizontal tube 5 is rotated to be parallel to the side wall of the sand box 21 by adjusting the assembly, so that the casting can be taken out after subsequent pouring.

[0042] Specifically, a ratchet gear 66 is fixedly provided on the reel 61, and a ratchet block 67 is rotatably provided on the reciprocating seat 6. A torsion spring is provided between the ratchet block 67 and the reciprocating seat 6, and the ratchet block 67 is engaged with the ratchet gear 66. When the hook 63 is pulled to hang the model, the second connecting rope 62 pulls the reel 61 to rotate, and the spiral spring is tightened. Under the action of the torsion spring, the ratchet block 67 does not affect the rotation of the reel 61 when the second connecting rope 62 is pulled out. After the second connecting rope 62 is pulled out, the ratchet block 67 is engaged with the ratchet gear 66 to avoid the spiral spring driving the reel 61 to rotate in the opposite direction after the second connecting rope 62 is pulled out, thereby ensuring the stability of the hook 63 after hanging the model.

[0043] In an embodiment further provided by the present invention, an abutment block 52 is slidably provided on the transverse tube 5, an abutment portion 68 is provided on the ratchet block 67, the abutment portion 68 abuts and cooperates with the abutment block 52, and an inclined surface is provided on the abutment block 52; a plurality of second springs 53 are provided between the abutment block 52 and the transverse tube 5, and the two ends of the second spring 53 are respectively fixedly connected to the abutment block 52 and the transverse tube 5, and when the reciprocating block slides to make the hook 63 and the model descend to the inside of the sand box 21, the abutment portion 68 and the abutment block 52 are in contact with each other. Under the action of the inclined surface, the abutment block 52 is pushed to slide, the second spring 53 is compressed, the ratchet block 67 and the ratchet gear 66 are always engaged to ensure the stability of the reel 61. When the reciprocating block is reset, the ratchet block 67 abuts against the straight surface of the other end of the abutment block 52, and under the action of the abutment block 52, it overcomes the force of the torsion spring and rotates. The ratchet block 67 is disengaged from the ratchet gear 66, so that the reel 61 rotates under the action of the spiral spring to reel in the second connecting rope 62, thereby completing the retraction of the hook 63.

[0044] Furthermore, a clamping seat 64 is slidably provided on the reciprocating seat 6, and a plurality of third springs 65 are provided between the clamping seat 64 and the reciprocating seat 6, and the two ends of the third spring 65 are respectively fixedly connected to the clamping seat 64 and the reciprocating seat 6, and the unhooking component includes a limiting plate 7 slidably provided on the cross tube 5, and a limiting hole 73 is provided on the limiting plate 7, and the second connecting rope 62 passes through the limiting hole 73; a telescopic plate 71 is slidably provided on the limiting plate 7, and the telescopic plate 71 abuts against the cross tube 5, and a plurality of fourth springs 72 are provided between the telescopic plate 71 and the limiting plate 7, and the two ends of the fourth spring 72 are respectively fixedly connected to the telescopic plate 71 and the limiting plate 7, and when the reciprocating seat 6 is reset and slid and the hook 63 is retracted, the clamping seat 64 is pulled, and at this time, the reciprocating seat 6 does not move. The clamping seat 64 slides with the limiting plate 7 and limits the second connecting rope 62 through the limiting hole 73. The hook 63 on the second connecting rope 62 is away from the model to prevent the hook 63 from colliding with the model during the retraction process. When the limiting plate 7 slides with the clamping seat 64, the telescopic plate 71 abuts against the cross tube 5, and the fourth spring 72 is compressed. After the hook 63 is recovered, the clamping seat 64 is separated from the limiting plate 7, and the limiting plate 7 is reset under the action of the fourth spring 72. In addition, during the sliding process of the clamping seat 64, the reciprocating seat 6 does not move, and the third spring 65 is stretched. After the limiting plate 7 slides to the maximum value and separates from the clamping seat 64, the reciprocating seat 6 slides under the action of the third spring 65 to restore its relative position with the clamping seat 64.

[0045] Furthermore, a clamping plate 8 is slidably provided on the limit plate 7, a first clamping portion 81 is fixedly provided on the clamping plate 8, the first clamping portion 81 is clamped with the clamping seat 64, a clamping rod 84 is slidably provided on the clamping plate 8, the clamping rod 84 is slidably connected with the cross tube 5, a second clamping portion 85 is fixedly provided on the clamping rod 84, the second clamping portion 85 is clamped with the reciprocating seat 6, a plug interface 83 is provided on the clamping plate 8, a plug pin 51 is fixedly provided on the cross tube 5, the plug pin 51 is slidably plugged with the plug interface 83, and both the plug pin 51 and the plug interface 83 are provided with inclined surfaces, and are connected through The first and second clamping parts 81 and 85 are in contact with each other through the inclined surface; a plurality of fifth springs 82 are arranged between the clamping plate 8 and the limiting plate 7, and the two ends of the fifth spring 82 are respectively fixedly connected with the clamping plate 8 and the limiting plate 7. When the clamping seat 64 and the reciprocating seat 6 slide to make the hook 63 drop into the sand box 21, the clamping seat 64 and the reciprocating seat 6 pass through the inclined surface of the first clamping part 81 and the inclined surface of the second clamping part 85 respectively, and the clamping seat 64 is engaged with the first clamping part 81, and the reciprocating seat 6 is engaged with the second clamping part 85. When the hook 63 is retracted, the sliding tube 4 and the horizontal tube 5 are lowered to make the hook 63 detach from the model. The first clamping portion 81 drives the clamping plate 8 and the limiting plate 7 to slide, so that the hook 63 moves away from the model under the action of the limiting hole 73. When the limiting plate 7 slides to the maximum value, the plug pin 51 is plugged into the plug interface 83, and the plug interface 83 is plugged into the plug pin 51. The inclined surface of the plug interface 83 at the abutment of the plug pin 51 causes the clamping plate 8 to move downward, and the fifth spring 82 is squeezed. The first clamping portion 81 is disengaged from the clamping seat 64, and the clamping plate 8 moves downward with the clamping rod 84, so that the second clamping portion 85 is disengaged from the reciprocating seat 6, and the reciprocating seat 6 is completed. The seat 6 is unlocked, and then the reciprocating seat 6 slides with the clamping seat 64, and with the cooperation of the abutment block 52 and the ratchet block 67, the ratchet block 67 and the ratchet gear 66 are unlocked, so that the spiral spring drives the reel 61 to rotate to reel in the second connecting rope 62, completing the retraction of the hook 63, and after the first clamping portion 81 is disengaged from the clamping seat 64, the limit plate 7 is reset under the action of the fifth spring 82. It should be noted that the plug interface 83 is larger than the plug pin 51. When the clamping plate 8 slides, the inclined surface of the plug interface 83 and the inclined surface of the plug pin 51 are squeezed to move the clamping plate 8 downward.

[0046] In an embodiment further provided by the present invention, the adjustment assembly includes a lifting rod 41 slidably arranged on the sliding tube 4, a guide block 43 is fixedly arranged on the lifting rod 41, a guide groove is arranged on the fixed tube 3, the guide block 43 is slidably arranged in the guide groove, and the guide groove includes a rotating part 31 and a lifting part 32; a first connecting rope 44 is arranged between the lifting rod 41 and the clamping seat 64, and the two ends of the first connecting rope 44 are respectively fixedly connected to the lifting rod 41 and the clamping seat 64; a first spring 42 is arranged between the lifting rod 41 and the sliding tube 4, and the two ends of the first spring 42 are respectively fixedly connected to the lifting rod 41 and the sliding rod, and when the lifting rod 41 moves from the rotating part 31 of the guide groove to the lifting part 32, At the same time, the sliding tube 4 is driven to rotate, so that the cross tube 5 is rotated to the top of the sand box 21, and after the rotation, the lifting rod 41 moves up, and the first connecting rope 44 is loosened. Under the gravity of the hook 63 and the model, the reciprocating seat 6 and the clamping seat 64 slide, so that the hook 63 and the model are lowered into the sand box 21. After the model and the hook 63 are lowered into the sand box 21, the lifting rod 41 abuts against the sliding tube 4, the first spring 42 rebounds, and the jacking device 11 is started, pushing the sand box 21 to move up and separate from the conveying vehicle 2. At this time, the lifting rod 41 continues to move up, which can push the sliding tube 4 to slide and move up, so that the hook 63 and the model are moved up synchronously to ensure that the model is located in the sand box 21.

[0047] In the embodiment provided by the present invention, a screw rod 22 is rotatably provided on the conveying vehicle 2, and the screw rod 22 is threadedly connected with the lifting rod 41. A driving motor 23 is fixedly provided on the conveying vehicle 2, and the motor shaft of the driving motor 23 is fixedly connected with the screw rod 22; pulleys 24 are fixedly provided on the screw rods 22 on both sides, and a belt 25 is provided for transmission between the two pulleys 24. When the screw rod 22 rotates and the lifting rod 41 moves upward, the screw 22 first rotates with the lifting rod 41 through the cooperation of the guide block 43 and the rotating part 31 of the guide groove. After the guide block 43 moves from the rotating part 31 to the lifting part 32, The screw rod 22 continues to rotate, and under the abutment of the side wall of the lifting part 32, the screw rod 22 rotates to make the lifting rod 41 move upward. After the screw rod 22 reverses to make the lifting rod 41 descend, the guide block 43 descends to the connection between the lifting part 32 and the rotation. At this time, the screw rod 22 continues to flip to make the lifting rod 41 drive the sliding tube 4 to rotate, so that the cross tube 5 moves to a state parallel to the side wall of the sand box 21, which is convenient for subsequent pouring construction. In addition, through the transmission between the driven pulley 24 and the belt 25, the screw rods 22 on both sides rotate synchronously, thereby completing the synchronous descent and retraction of the hooks 63 on both sides.

[0048] An intelligent casting island includes the above-mentioned casting mold vibrating and compacting mechanism, so the intelligent casting island should also have the effects brought by the above-mentioned casting mold vibrating and compacting mechanism, which will not be described one by one.

[0049] In the present invention, the vibration device 12 is used to vibrate and compact the molding sand in the sand box 21, the lifting device 11 is used to lift the sand box 21 to separate it from the conveyor vehicle 2, and the sand adding device is used to add molding sand into the sand box 21. The model is a combustible foam plastic model, and the conveyor vehicle 2 and conveyor frame 1 mentioned are all prior arts. The specific implementation methods and the effects they have are common knowledge and conventional technical means known to people in this field, and will not be elaborated in detail.

[0050] Working principle: when placing the model, the driving motor 23 drives the screw 22 to rotate. At this time, the lifting rod 41 rotates with the rotation of the screw 22, and drives the sliding tube 4 to rotate, so that the cross tube 5 is placed horizontally above the sand box 21. At the same time, the guide block 43 is moved from the rotating part 31 of the guide groove to the lifting part 32, and then the hooks 63 on both sides of the sand box 21 are pulled to hang the model. In the process of pulling the hook 63, the second connecting rope 62 pulls the reel 61 to rotate and tightens the volute spring. At the same time, under the engagement of the ratchet block 67 and the ratchet gear 66, the reel 61 is prevented from reversing under the action of the volute spring; then the driving motor 23 continues to drive the screw 22 to rotate. At this time, the lifting rod 41 rises upward, and the first spring 42 is compressed and The first connecting rope 44 is loosened and the hook 63 and the model are subjected to the gravity action. The clamping seat 64 and the reciprocating seat 6 slide to make the hook 63 move downward and lower the model into the sand box 21. At this time, the lifting rod 41 abuts against the sliding tube 4, the first spring 42 rebounds, and the reciprocating seat 6 is clamped with the second clamping portion 85, and the clamping seat 64 is clamped with the first clamping portion 81. Then the conveying vehicle 2 moves to the bottom of the sand adding device, and then the lifting device 11 is started to push the sand box 21 to move up and separate from the conveying vehicle 2. At the same time, the driving motor 23 is started, and the lifting rod 41 is moved up with the sliding tube 4 and the cross tube 5 through the screw 22, so that the model and the sand box 21 are moved up together to ensure the position of the model in the sand box 21. Then the vibration device 12 and the sand adding device are started. After the molding sand in the box buries a part of the model, it is unhooked and the driving motor 23 rotates in the opposite direction, and the lifting rod 41 and the sliding rod are lowered through the screw 22. Because the molding sand supports the model at this time, when the sliding rod and the cross tube 5 move down, the hook 63 is separated from the model under the action of its own gravity. Then, after the sliding tube 4 and the cross tube 5 are lowered and reset, the hook 63 is lowered and separated from the model. Then, the driving motor 23 continues to reverse, so that the lifting rod 41 moves down and compresses the first spring 42, the sliding tube 4 and the cross tube 5 are stationary, and the lifting rod 41 pulls the first connecting rope 44, so that the clamping seat 64 slides with the limit plate 7 through the first clamping portion 81, the reciprocating seat 6 and the second clamping portion 85 are clamped and stationary, and the limit plate 7 slides through the limit hole 73. The second connecting rope 62 is adjusted so that the second connecting rope 62 moves away from the model with the hook 63 to avoid collision with the model during the retraction process of the hook 63. When the hook 63 moves to the plug pin 51 and the plug interface 83, the clamping plate 8 moves down with the clamping rod 84 under the action of the inclined surface, the first clamping portion 81 is disengaged from the clamping seat 64, the second clamping portion 85 is disengaged from the reciprocating seat 6, and under the pulling force of the third spring 65, the reciprocating seat 6 slides to lift the hook 63. At the same time, under the action of the fourth spring 72, the limit plate 7 is reset, and the hook 63 is further lifted by pulling the second connecting rope 62, so that the hook 63 moves up to a position higher than the model. At this point, the unhooking is completed. Subsequently, the screw rod 22 continues to rotate to reset the lifting rod 41, andDuring the resetting process of the reciprocating seat 6, the ratchet block 67 abuts against the abutment block 52. Since the abutment is not an inclined surface, the abutment block 52 will not compress the second spring 53. Under the resetting sliding action of the reciprocating seat 6, the ratchet block 67 overcomes the force of the torsion spring and rotates and disengages from the ratchet block 67. At this time, under the action of the spiral spring, the reel 61 reels the second connecting rope 62 to complete the recovery and resetting of the hook 63. After the lifting rod 41 moves to the bottom, the guide block 43 enters the rotating part 31 from the lifting part 32 under the rotation of the screw rod 22, completing the rotation and resetting of the cross tube 5 and the sliding tube 4, so that the cross tube 5 is parallel to the side of the sand box 21, which is convenient for subsequent pouring. After completing the resetting of each position, the model is partially buried by the molding sand, and then the sand is continued to be added and vibrated, so that the molding sand can be vibrated and compacted while ensuring the stability of the model.

[0051] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
