Description

Technical Field

[0001] The present invention belongs to the technical field related to casting processing, and particularly relates to a casting shell shaking device. Background Art

[0002] In modern casting production processes, casting shell shaking equipment is the core equipment for separating castings from mold shells. Traditional casting shell shaking equipment mainly relies on vibrating components, such as the mechanical vibration generated by pneumatic picks, to prompt the separation of the mold shell from the casting. However, in actual production processes, the shaken-off mold shells are often difficult to directly recycle due to their large sizes. The unbroken large-sized mold shells not only occupy a large amount of space in the collection and storage links, but also cannot meet the feeding requirements of conventional recycling equipment during subsequent crushing and reprocessing. This not only leads to low recycling efficiency but also increases the cost and difficulty of resource reuse. Summary of the Invention

[0003] The purpose of the present invention is to provide a casting shell shaking device to solve the problem in the above-mentioned background art that traditional shell shaking equipment is inconvenient for recycling the fallen mold shells.

[0004] The present invention is implemented as follows. A casting shell shaking device includes a box body.

[0005] A hollow support is fixed inside the box body, and a fixed box is fixed on the top of the hollow support. A vertical rod is disposed through the interior of the fixed box, and a hollow fixed frame is fixed to the top of the vertical rod. A shell shaking mechanism is arranged on the top of the box body. Both ends of the top of the vertical rod are fixed with L-shaped crushing plates, and crushing teeth one are fixed to the side parts of the L-shaped crushing plates. Fixed blocks are fixed to both ends of the inner wall of the box body, and crushing teeth two are fixed to the side parts of the fixed blocks. The bottom of the L-shaped crushing plate is installed with a crushing inclined plate through an ear plate, and a grinding sheet one is fixed to the side part of the crushing inclined plate. A grinding sheet two is fixed to the side of the bottom of the fixed block.

[0006] An adjustment mechanism is arranged on the vertical rod, and the adjustment mechanism is used to adjust the angle of the crushing inclined plate.

[0007] An elastic driving mechanism is arranged inside the fixed box, and a dust suction mechanism is arranged on the top of the box body.

[0008] In the above technical solution, when the mold shell mechanism performs the mold shell shaking operation on the casting, during the shaking process, the mold shell will fall into the gap between the L-shaped crushing plate and the fixed block. Since the shaking force will be transmitted to the hollow fixed frame and the vertical rod, and since there is an elastic driving mechanism inside the fixed box, it will undergo compression and rebound deformation when subjected to the shaking force. This deformation causes the vertical rod to move reciprocally in the vertical direction. At the same time, the L-shaped crushing plates fixed on both sides of the vertical rod will move synchronously with the vertical movement of the vertical rod, so that the crushing teeth on the side of the L-shaped crushing plate cooperate with the crushing teeth on the other side to initially crush the fallen mold shell during the up and down reciprocation process. And the grinding plates will perform secondary grinding on the crushed mold shell, further refining the mold shell into smaller particles, which is convenient for subsequent recycling and reuse of the mold shell.

[0009] Preferably, the mold shell shaking mechanism includes a hydraulic cylinder, the hydraulic cylinder is fixedly installed through the two ends of the top of the box body, and the output end of the hydraulic cylinder is fixed with a mounting plate, and a pneumatic pick is arranged on the mounting plate.

[0010] In the above technical solution, the hydraulic cylinder drives the mounting plate and the pneumatic pick to descend. After the pneumatic pick abuts against the casting, the mold shell shaking operation can be carried out.

[0011] Preferably, the adjusting mechanism includes a lead screw, the lead screw is vertically installed inside the vertical rod, and a movable block is threadedly connected to the lead screw. Both ends of the movable block are connected to the crushing inclined plate through adjusting rods. An empty groove is opened on the vertical rod, and a handwheel is arranged in the empty groove, and the handwheel is connected to the lead screw.

[0012] In the above technical solution, by rotating the handwheel to drive the lead screw to rotate, the lead screw can drive the movable block threadedly connected to it to move vertically. During the vertical movement of the movable block, both ends of the adjusting rod will rotate on the movable block and the crushing inclined plate respectively, and will drive the crushing inclined plate to rotate around its intersection with the L-shaped crushing plate, thereby driving the crushing inclined plate to adjust the angle. By adjusting the angle of the crushing inclined plate, the distance between the grinding plate on the side of the crushing inclined plate and the grinding plate on the side of the fixed block can be adjusted. In this way, during grinding, the fineness of the secondary grinding of the mold shell can be adjusted, and it can be flexibly adapted to diverse recycling scenarios.

[0013] Preferably, a toothed ring is sleeved on the handwheel, and limit bolts are arranged at both ends of the side of the vertical rod, and the limit bolts penetrate through the empty groove and are in contact with the toothed ring.

[0014] In the above technical solution, after rotating the handwheel, in order to prevent the lead screw from rotating automatically during vibration, resulting in the loosening of the crushing inclined plate, the limit bolt can be rotated to make it snap into the tooth groove of the toothed ring on the outside of the handwheel, thereby locking the toothed ring, the handwheel and the lead screw, and improving the stability during use.

[0015] Preferably, a collection box is arranged at the bottom of the hollow support.

[0016] In the above technical solution, the collection box can collect the broken and ground mold shells.

[0017] Preferably, the elastic driving mechanism includes a bottom plate fixed to the bottom of the vertical rod. A through hole is formed at the top of the fixed box, and the vertical rod is located in the through hole. Springs are fixed to both ends of the top of the fixed box and are fixedly connected to the bottom plate.

[0018] In the above technical solution, the through hole can guide the vertical movement of the vertical rod so that it can only move vertically. When the vertical rod is vibrated, the spring will deform, and thus the bottom plate and the vertical rod are driven to perform vertical reciprocating motion through the deformation of the spring.

[0019] Preferably, the dust suction mechanism includes a dust suction box fixed to the top of the box body. An air pump is arranged at the top of the dust suction box. Both ends of the dust suction box are connected to a dust suction hood through a delivery pipe, and the dust suction hood is installed above the side of the fixed block.

[0020] In the above technical solution, during the process of breaking the mold shell, air can be pumped through the air pump, so that suction is generated inside the dust suction box. At the same time, the dust suction box will also cause suction at the dust suction hood through the delivery pipe, so that the scattered dust can be adsorbed during the process of breaking the mold shell, avoiding the dust from spreading everywhere and polluting the environment, and improving its environmental protection performance.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] (1) During the process of vibrating the mold shell, the elastic potential energy of the elastic driving mechanism is converted into kinetic energy to drive the vertical reciprocating motion of the L-shaped crushing plate and the crushing inclined plate, so that the crushing teeth one on the side of the L-shaped crushing plate cooperate with the crushing teeth two to initially crush the dropped mold shell during the up and down reciprocating process. When the L-shaped crushing plate moves vertically in a reciprocating manner, it will also drive the crushing inclined plate and the grinding piece one to move vertically in a reciprocating manner to extrude and grind the broken mold shell, so as to perform secondary grinding on the broken mold shell. Through multi-stage grinding, the mold shell can be further refined into smaller particles, improving the recycling value of the mold shell. Moreover, no additional crushing power device needs to be equipped, reducing the production energy consumption. And the mold shell is crushed synchronously during the process of vibrating the mold shell, without transfer and other operations, improving the production continuity;

[0023] (2) By rotating the handwheel to drive the lead screw to rotate, the lead screw can drive the movable block to move vertically. During the vertical movement of the movable block, the adjusting rod will drive the crushing inclined plate to rotate around its intersection with the L-shaped crushing plate, thereby driving the crushing inclined plate to adjust the angle. By adjusting the angle of the crushing inclined plate, the distance between the grinding sheet I on the side of the crushing inclined plate and the grinding sheet II on the side of the fixed block can be adjusted. In this way, during grinding, the secondary grinding fineness of the mold shell can be adjusted, and it can be flexibly adapted to diverse recycling scenarios. For example, different recycling processes and downstream applications have different requirements for the fineness of mold shell particles, improving the versatility and applicability of mold shell recycling.

[0042] Please refer to Figures 1-4 , in this embodiment: The elastic driving mechanism 18 includes a bottom plate 1801 fixed to the bottom of the vertical rod 4.

[0044] Please refer to Figure 1 , in this embodiment: The dust suction mechanism 19 includes a dust suction box 1901 fixed to the top of the box body 1. An air pump 1902 is arranged at the top of the dust suction box 1901.

[0045] Working principle and usage process of the present invention: When in use, first place the casting of the shell to be vibrated in the hollow fixing frame 5, and fix the casting through the casting fixator. Then, the hydraulic cylinder 601 can be opened to drive the mounting plate 602 and the pneumatic pick 603 to descend for the shell vibrating operation of the casting. During the shell vibrating process, the vibration force will be transmitted to the hollow fixing frame 5 and the vertical rod 4. The spring 1802 inside the fixed box 3 will undergo compression and rebound deformation when subjected to the vibration force. This deformation causes the vertical rod 4 to generate reciprocating movement in the vertical direction. At the same time, the L-shaped crushing plates 7 fixed on both sides of the vertical rod 4 will move synchronously with the vertical movement of the vertical rod 4, so that the crushing teeth one 8 on the side of the L-shaped crushing plate 7 cooperate with the crushing teeth two 10 on the side of the fixed block 9 to initially crush the dropped mold shell during the up and down reciprocation. With the up and down reciprocating movement of the L-shaped crushing plate 7, the crushed mold shell will fall between the crushing inclined plate 11 and the fixed block 9. Since the gap between the crushing inclined plate 11 and the fixed block 9 continuously decreases from top to bottom, when the L-shaped crushing plate 7 makes vertical reciprocating movement, it will also drive the crushing inclined plate 11 and the grinding piece one 12 to make vertical reciprocating movement, and cooperate with the grinding piece two 13 on the side of the fixed block 9 to extrude and grind the crushed mold shell, so as to perform secondary grinding. Through secondary grinding, the mold shell can be further refined into smaller particles, improving the recycling value of the mold shell. During the shell vibrating operation, air can be pumped through the air pump 1902, so as to generate suction inside the dust collection box 1901. At the same time, the dust collection box 1901 will also make the dust collection hood 1904 generate suction through the conveying pipe 1903, so that the scattered dust can be adsorbed during the shell vibrating process and the mold shell crushing process. When it is necessary to adjust the fineness of the secondary grinding of the mold shell, the handwheel 1404 can be rotated to drive the lead screw 1401 to rotate, so that the lead screw 1401 can drive the movable block 1402 threadedly connected thereto to make vertical movement. During the vertical movement of the movable block 1402, both ends of the adjusting rod 1403 will rotate on the movable block 1402 and the crushing inclined plate 11 respectively, and will drive the crushing inclined plate 11 to rotate around its intersection with the L-shaped crushing plate 7, so as to drive the crushing inclined plate 11 to adjust the angle. By adjusting the angle of the crushing inclined plate 11, the distance between the grinding piece one 12 on the side of the crushing inclined plate 11 and the grinding piece two 13 on the side of the fixed block 9 can be adjusted, so that the fineness of the secondary grinding of the mold shell can be adjusted during grinding, and thus it can be flexibly adapted to diverse recycling scenarios.
