Description

Technical Field

[0001] This utility model relates to the field of casting technology, specifically to an automatic sand removal device for casting. Background Technology

[0002] Slatted floor panels for livestock farming are typically manufactured using a casting process, which requires foundry sand as the mold material. After casting, the formed panels need to be removed from the foundry sand, a process traditionally done manually. However, this manual sand removal method presents numerous safety and instability risks, severely impacting production efficiency, worker safety, and product quality.

[0003] 1. Unsafe factors

[0004] During the manual sand removal process, workers need to directly contact the high-temperature castings and heavy molds, which can easily lead to the following safety hazards:

[0005] Risk of burns from high temperatures: The temperature of the newly cast manure slab and the surrounding casting sand is very high, and serious burns may occur if the operator is not careful during manual operation.

[0006] Dust hazards: Foundry sand generates a large amount of dust during the sand removal process. Long-term inhalation may lead to occupational diseases such as silicosis, endangering workers' health.

[0007] Mechanical injury risk: When manually handling or striking the mold, improper operation may cause the mold to break and fly out, resulting in scratches or impact injuries.

[0008] Risks of heavy physical labor: Slatted floor panels and molds are usually quite heavy, and manual handling can easily cause occupational diseases such as muscle strain and joint injury.

[0009] 2. Unstable factors

[0010] Besides safety hazards, artificial sand removal also presents the following problems:

[0011] Low efficiency: Manual operation is slow and cannot meet the needs of large-scale production, becoming a bottleneck in the casting production line.

[0012] Unstable quality: Manual knocking or handling may cause deformation and surface damage to the castings, affecting the dimensional accuracy and service life of the manure slatted floor.

[0013] Low sand mold recycling rate: Manual sand removal can easily cause the casting sand to break or become mixed with impurities, reducing the recycling rate of sand molds and increasing production costs.

[0014] High labor intensity: Long-term repetitive high-intensity work can easily lead to worker fatigue, further increasing the risk of operational errors and accidents.

[0015] In conclusion, traditional manual sand removal methods are no longer adequate for the modern foundry industry's higher demands for safety, efficiency, and quality. Therefore, there is an urgent need to develop an automated and intelligent sand removal device and process to address these issues and improve the safety and stability of the casting production of slatted floor slabs for livestock farming.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0044] Please see Figure 1-6 The present invention provides the following technical solution: an automatic sand removal device for casting, including an upper support 4, a track frame 2 fixedly installed on the upper end face of the upper support 4, a moving trolley 1 fixedly connected to the upper end face of the track frame 2, a lifting push rod 9 fixedly installed on the upper end face of the moving trolley 1, a sand pushing mechanism 8 fixedly installed on the lower end face of the lifting push rod 9, an upper and lower sand box separation device 3 provided on the lower side of the upper support 4, and a flipping device 7 provided on the lower side of one side of the upper support 4, the flipping device 7 including a workpiece and casting sand separation point 71 and a flipping trolley 72;

[0045] The sand pushing mechanism 8 includes a lifting support plate 88 fixedly installed with the lifting push rod 9. A mounting plate A81 is symmetrically installed on the upper end face of the lifting support plate 88. Several lifting cylinders 82 are fixedly installed on the upper end face of the lifting support plate 88. The lifting cylinders 82 pass through the lifting support plate 88 and are jointly fixedly installed on the mounting plate B83. Several mounting rods 84 are fixedly installed on the lower end face of the mounting plate B83. Casting sand push plates 85 are fixedly installed on the lower end face of each of the mounting rods 84. Four inclined mounting plates 86 with gripping hook structures are symmetrically installed on the outer side of the mounting plate A81. Two gripping hook structures 87 are fixedly installed on each of the inclined mounting plates 86 with gripping hook structures.

[0046] In this embodiment, the connection between the upper support 4 and the track frame 2 is welded. The main function of the track frame 2 is to provide a track for the mobile trolley 1 and support the sand pushing mechanism 8. The mobile trolley 1 is bolted with a lifting push rod 9, which is a hydraulic push rod. The main function of the lifting push rod 9 is to lift the sand pushing mechanism 8. The main function of the sand pushing mechanism 8 is to clean the casting sand inside the sand box 5 after the upper and lower parts are separated. The sand pushing mechanism 8 works with the upper and lower sand box separation device 3 to achieve the upper and lower separation of the sand box 5. The flipping device 7 is divided into a workpiece and casting sand separation point 71 and a flipping trolley 72. The main function of the casting sand separation point 71 is to separate the casting sand from the manure plate when it is placed on it. The main function of the flipping trolley 72 is to transport the manure plate separated from the sand box to the casting sand separation point 71, and to make the manure plate fall onto the casting sand separation point 71 by flipping the trolley 72 to separate the casting from the casting sand.

[0047] The lifting support plate 88 and the lifting push rod 9 are connected by bolts. The lifting and lowering of the sand pushing mechanism 8 is realized by the lifting and lowering of the lifting push rod 9. The main function of the mounting plate A81 is to install the gripping hook structure. Seven are fixedly installed on the lifting support plate 88. The lifting cylinder 82 and the mounting plate B83 are connected by bolts. The main function of the mounting plate B83 is to connect the lifting cylinder 82 and the mounting rod 84. There are 20 mounting rods 84. The lower end of each mounting rod 84 is welded with a casting sand push plate 85. Two are symmetrically arranged on the mounting plate A81. Two gripping hook structure inclined mounting plates 86 are welded on each mounting plate A81. Two gripping hook structure inclined mounting plates 86 are then installed by bolts.

[0048] The trolley 1 moves the sand pushing mechanism 8 above the sand box 5, and then the lifting push rod 9 moves the sand pushing mechanism 8 down to the sand box. At this time, the gripping hook structure 87 grips the sand box 5. Then the lifting push rod 9 rises, and the trolley 1 moves to the top of the sand box separation device 3. Then the lifting push rod 9 lowers the sand pushing mechanism 8 down to the sand box separation point 31 of the sand box separation device 3.

[0049] Specifically, the gripping hook structure 87 includes an inclined push cylinder 871 fixedly installed on the side of the inclined mounting plate 86 of the gripping hook structure. A rotating shaft connection 872 is fixedly installed on one side of the inclined push cylinder 871. An upper hook claw 873 and a lower hook claw 874 are fixedly installed on the rotating shaft connection 872 respectively.

[0050] The upper claw 873 is longer than the lower claw 874.

[0051] In this embodiment, the main function of the tilting push cylinder 871 is to adjust the position of the two hooks by extending and retracting. The upper hook 873 is used to hook the lower sand box 5, and the lower hook 874 is used to hook the upper sand box 5, so that the sand box 5 can be clamped and lifted at one time.

[0052] By extending the tilting cylinder 871, the two hooks will grasp the sand box 5 under the action of the lifting support plate 88. Similarly, when retracting, the two hooks will relax and release the sand box 5.

[0053] Specifically, the upper and lower sand box separation device 3 includes a sand box separation part 31 and a casting support rod 32. The casting support rod 32 is fixedly installed on the lower side of the sand box separation part 31 and passes through the casting support rod 32.

[0054] The casting support rod 32 is a driven telescopic structure.

[0055] In this embodiment, the main function of the casting support rod 32 is that when the sand pushing mechanism 8 moves the sand box 5 to the sand box separation point 31 with the cooperation of other mechanisms, it will first release the lower hook 874, but at this time the upper hook 873 is still hooked on the upper sand box 5. At this time, the lifting push rod 9 will drive the sand pushing mechanism 8 to move upward, thereby opening the upper sand box 5. At this time, the lower hook 874 that was just released will hook the casting support rod 32. With its rise and fall, the casting support rod 32 will rise and fall, thereby supporting the casting inside the sand box.

[0056] At this time, the sand pushing mechanism 8 descends again under the action of the lifting push rod 9, thereby clamping the lower half of the sand box 5 and then rising. At this time, the lifting cylinder 82 extends and pushes out the mounting plate B83, thereby pushing out the casting sand push plate 85, thus cleaning the casting sand remaining in the sand box 5. Then the sand pushing mechanism 8 brings the sand box back to the sand box moving carrier 6 and flows out from the side away from the flipping device 7 into the next cycle.

[0057] Specifically, the tilting trolley 72 includes a guide rail 727, a base plate 726 is movably mounted on the upper side of the guide rail 727, a counterweight 724 and an electrical distribution box 725 are fixedly mounted on the upper surface of the base plate 726, a frame 722 is also fixedly mounted on the upper surface of the base plate 726, a rotating motor base 728 is fixedly mounted on the upper surface of the base plate 726 and inside the frame 722, a rotating motor 723 is fixedly mounted on the upper surface of the rotating motor base 728, and a receiving device 721 is fixedly mounted on one side of the rotating motor 723.

[0058] In this embodiment, the tilting trolley 72 moves linearly back and forth on the guide rail 727. After the casting support rod 32 supports the casting, the tilting trolley will start, so that the receiving device 721 is below the casting. At this time, the lower hook 874 is released again, so that the casting support rod 32 descends, causing the casting (manure leakage plate) to fall onto the receiving device 721. Then the tilting trolley 72 returns to the casting sand separation point 71. At this time, the rotating motor 723 starts, dropping the casting onto the casting sand separation point 71.

[0059] Specifically, the track frame 2 includes a bracket 21 fixedly installed on the upper end face of the upper bracket 4. Several tracks 23 and a limiting plate 22 are fixedly installed on the upper end face of the bracket 21. A mobile trolley 1 is movably installed on the upper end face of the limiting plate 22. One end of a hydraulic moving push rod 24 is also fixedly installed on one side of the bracket 21. The other end of the hydraulic moving push rod 24 is fixedly installed on the mobile trolley 1.

[0060] In this embodiment, the upper support 4 is connected to the support 21 by welding. The support 21 is provided with two tracks 23, which are used to provide tracks for the mobile trolley 1. The main function of the limiting plate 22 is to prevent the mobile trolley 1 from falling off the track. The movement of the mobile trolley 1 is achieved by hydraulic moving push rod 24.

[0061] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
