Description

Technical Field

[0001] This utility model relates to the field of sand casting production technology, specifically a mold assembly device for iron mold sand casting production. Background Technology

[0002] Sand casting is a traditional casting process that uses sand as the main molding material to make molds. Steel, iron, and most non-ferrous alloy castings can be obtained using sand casting. Sand molds are generally made using gravity casting, but low-pressure casting, centrifugal casting, and other processes can also be used when there are special requirements. Because the molding materials used in sand casting are inexpensive and readily available, and the mold making is simple, it can adapt to single-piece production, batch production, and mass production of castings. Especially in small-batch and large-part production, its price advantage is particularly prominent. Therefore, it has long been a basic process in casting production. In addition, sand molds have high refractoriness, so materials with high melting points, such as copper alloys and ferrous metals, are also often produced using this process.

[0003] Chinese Patent Publication No. CN206981722U discloses "A Casting Box Closing Device", which includes an upper sand box and a lower sand box. The lower surface of the upper sand box is provided with a columnar protrusion, and the lower end of the columnar protrusion is provided with a conical positioning block. The lower sand box has a slot, and a gear is installed in the slot. A first rack meshes with the left side of the gear. The upper end of the first rack is fixed with a handle, forming a structure in which the handle and the first rack slide vertically together. The handle is provided with a conical positioning hole corresponding to the conical positioning block. A second rack that slides vertically is meshed with the left side of the gear. The upper end face of the second rack is flush with the upper end face of the lower sand box. The upper sand box has a cavity, and the second rack can slide into the cavity. The sand box and the lower sand box can achieve multiple positioning during the box closure process, with high positioning accuracy, high positioning precision, and high reliability.

[0004] While existing technology allows for the assembly of sand boxes, it requires lifting tools to lift and assemble the sand box. Furthermore, the top of the sand box lacks any securing device, making it difficult to lift and transport smoothly. This assembly process is also prone to accidents. Additionally, failure to align the upper and lower boxes before assembly can lead to significant misalignment. Due to the weight of the boxes, adjustment is difficult and can cause internal wear and even damage. Utility Model Content

[0005] The purpose of this utility model is to provide a box-closing device for iron mold sand casting production, so as to solve the problems in the above-mentioned background technology. During use, it is necessary to use lifting tools to lift and close the upper sand box, and there is no device on the top of the upper sand box to fix the lifting tool, making it impossible to lift and transport the upper sand box smoothly. Moreover, the entire box-closing process is prone to dangerous accidents. In addition, if the upper and lower boxes are not aligned before closing, and the boxes are not aligned on the first closing, resulting in a large deviation, it is difficult to adjust due to the weight of the boxes themselves. This will also directly lead to wear and even damage to the internal parts of the existing technology.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a box-closing device for iron mold sand casting production, including a base plate, a hook assembly provided on the top of the base plate, and a moving assembly provided on the top of the base plate;

[0007] The hooking assembly includes a fixed plate, and a cylinder is fixedly connected to the top of the outer surface of the fixed plate. A telescopic column is provided inside the cylinder, and the telescopic column is slidably embedded inside the fixed plate. A push-pull plate is fixedly connected to the side of the telescopic column away from the cylinder. Multiple fixed rods are fixedly connected to one side of the outer surface of the fixed plate, and a support arm is rotatably sleeved on the outer surface of each of the multiple fixed rods. A hooking plate is fixedly connected to one side of the outer surface of each of the multiple support arms.

[0008] The movable component includes a threaded box, and a main threaded rod is rotatably embedded inside the threaded box. A main threaded block is threadedly fitted on the outer surface of the main threaded rod. A main limiting rod is provided inside the threaded box. The main threaded block is slidably fitted on the outer surface of the main limiting rod. A movable plate is fixedly connected to one side of the outer surface of the main threaded block, and multiple hydraulic rods are fixedly connected to the top of the outer surface of the movable plate. The sides of the multiple hydraulic rods away from the movable plate are all fixedly connected to the top of the outer surface of the fixed plate.

[0009] Preferably, a plurality of slides are fixedly connected to the top of the outer surface of the base plate, and a slider is slidably fitted on the outer surface of each of the slides, and a slide plate is fixedly connected to the top of the outer surface of each of the sliders.

[0010] Preferably, a threaded plate is fixedly connected to the top of the outer surface of the base plate, and an auxiliary threaded rod is rotatably embedded inside the threaded plate. An auxiliary threaded block is threadedly sleeved on the outer surface of the auxiliary threaded rod. An auxiliary limiting rod is provided inside the threaded plate. The auxiliary threaded block is slidably sleeved on the outer surface of the auxiliary limiting rod. The auxiliary threaded block is fixedly connected to the bottom of the outer surface of the slide plate.

[0011] Preferably, both sides of the outer surface of the push-pull plate are fixedly connected to fixed columns, and the outer surfaces of multiple fixed columns are rotatably fitted with large moving blocks. The interiors of multiple large moving blocks are rotatably embedded with first connecting rods, and the outer surfaces of multiple first connecting rods are rotatably fitted with small moving blocks. The interiors of multiple small moving blocks are rotatably embedded with second moving blocks, and multiple second moving blocks are rotatably embedded inside the support arm.

[0012] Preferably, a main motor plate is fixedly connected to one side of the outer surface of the thread box, and a main motor is provided on the top of the outer surface of the main motor plate. The output shaft of the main motor is fixedly connected to the main thread rod. Multiple back plates are fixedly connected to the top of the outer surface of the base plate, and the multiple back plates are all fixedly connected to one side of the outer surface of the thread box.

[0013] Preferably, an auxiliary motor plate is fixedly connected to one side of the outer surface of the threaded plate, and an auxiliary motor is provided on the top of the outer surface of the auxiliary motor plate, wherein the output shaft of the auxiliary motor is fixedly connected to the auxiliary threaded rod.

[0014] Preferably, each of the outer surfaces of the multiple hook plates is provided with a fixing ring, and the bottom of the outer surface of each of the multiple fixing rings is fixedly connected to an upper sand box, and the top of the outer surface of the slide plate is provided with a lower sand box.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] First, in use, this utility model utilizes a cylinder on a fixed plate. The cylinder contains a telescopic column, which extends and retracts to move a push-pull plate up and down. As the push-pull plate moves, the fixed column moves a large moving block, which in turn moves a small moving block connected to it via a first connecting rod. The small moving block is fixedly connected to a support arm via a second moving block. The support arm is rotatably mounted on the fixed rod. The small moving block pushes the support arm to rotate around the fixed rod, allowing multiple hook plates to pass through the fixed rings at the top of the upper sand box. At this point, the telescopic column retracts, and the support arm moves inward, hooking the multiple fixed rings onto the hook plates. This technical solution hooks and secures the upper sand box, facilitating subsequent transportation and use.

[0017] Secondly, this utility model involves activating the main motor at the top of the main motor plate. The output shaft of the main motor is fixedly connected to the main threaded rod. The main motor drives the main threaded rod to rotate, which in turn moves the main threaded block. The movement of the main threaded block, in turn, moves the moving plate. The moving plate is connected to the fixed plate via multiple hydraulic rods. Then, the auxiliary motor at the top of the auxiliary motor plate is activated. The output shaft of the auxiliary motor is fixedly connected to the auxiliary threaded rod. The auxiliary motor drives the auxiliary threaded rod to rotate, which in turn moves the auxiliary threaded block. The movement of the auxiliary threaded block, in turn, moves the sliding plate. The sliding plate moves via multiple hydraulic rods. The sliding block is mounted on the outside of the slide frame. The slide plate moves, thereby driving the lower sand box to move. The lower sand box is manually pushed to fit against the baffle set on the slide plate. The main thread block is moved to the farthest position near the main motor, and the slide plate is moved to the farthest position near the auxiliary motor. At this time, the upper sand box hooked by the hook plate and the lower sand box on the top of the slide plate are completely aligned and perpendicular. Then, the upper sand box is placed on top of the lower sand box by the hydraulic rod, and the connection between the hook plate and the fixing ring is disconnected by the cylinder. Through the above technical solution, the misalignment of the upper and lower sand boxes is avoided, which would cause the dimensional deviation of the product after casting.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 A box-closing device for iron mold sand casting production includes a base plate 1, a hook assembly is provided on the top of the base plate 1, and a moving assembly is provided on the top of the base plate 1.

[0025] The hooking assembly includes a fixed plate 3, and a cylinder 301 is fixedly connected to the top of the outer surface of the fixed plate 3. A telescopic column 302 is provided inside the cylinder 301, and the telescopic column 302 is slidably embedded inside the fixed plate 3. A push-pull plate 303 is fixedly connected to the side of the telescopic column 302 away from the cylinder 301. A plurality of fixed rods 406 are fixedly connected to one side of the outer surface of the fixed plate 3, and a support arm 404 is rotatably sleeved on the outer surface of the plurality of fixed rods 406. A hooking plate 405 is fixedly connected to one side of the outer surface of the plurality of support arms 404.

[0026] The movable component includes a threaded box 2, and a main threaded rod 201 is rotatably embedded inside the threaded box 2. A main threaded block 203 is threadedly sleeved on the outer surface of the main threaded rod 201. A main limiting rod 202 is provided inside the threaded box 2. The main threaded block 203 is slidably sleeved on the outer surface of the main limiting rod 202. A movable plate 204 is fixedly connected to one side of the outer surface of the main threaded block 203. A plurality of hydraulic rods 205 are fixedly connected to the top of the outer surface of the movable plate 204. The side of the plurality of hydraulic rods 205 away from the movable plate 204 is fixedly connected to the top of the outer surface of the fixed plate 3.

[0027] Through the above technical solution, during use, by activating the cylinder 301 on the fixed plate 3, a telescopic column 302 is installed inside the cylinder 301. The telescopic column 302 drives the push-pull plate 303 to move up and down. When the push-pull plate 303 moves, it drives the large moving block 4 to move through the fixed column 304. The movement of the large moving block 4 drives the connected small moving block 402 to move through the first connecting rod 401. The small moving block 402 is fixed to the support arm 404 through the second moving block 403. The support arm 404 is rotatably mounted on the fixed rod 406. The small moving block 402 pushes the support arm 404 to rotate around the fixed rod 406 as the center, so that multiple hook plates 405 pass through the fixed ring 501 at the top of the upper sand box 5. At this time, the telescopic column 302 is retracted. When the telescopic column 302 is retracted, the support arm 404 moves inward, thereby hooking the multiple fixed rings 501 onto the hook plates 405. Through the above technical solution, the upper sand box 5 is hooked and fixed, so as to facilitate subsequent transportation and use.

[0028] With the above technical solution, assuming the sand box 5 is already hooked and fixed, the main motor 9 at the top of the main motor plate 901 is activated. The output shaft of the main motor 9 is fixedly connected to the main threaded rod 201. The main motor 9 drives the main threaded rod 201 to rotate, which in turn moves the main threaded block 203. The movement of the main threaded block 203 then moves the moving plate 204. The moving plate 204 is connected to the fixed plate 3 via multiple hydraulic rods 205. Subsequently, the auxiliary motor 902 at the top of the auxiliary motor plate 903 is activated. The output shaft of the auxiliary motor 902 is fixedly connected to the auxiliary threaded rod 701. The auxiliary motor 902 drives the auxiliary threaded rod 701 to rotate, which in turn moves the auxiliary threaded block 703. The movement of the auxiliary threaded block 703 then moves the sliding plate. 802 moves, and the slide plate 802 is slidably sleeved on the outside of the slide frame 8 via multiple sliders 801. The movement of the slide plate 802 drives the lower sand box 6 to move. The lower sand box 6 is manually pushed to fit with the baffle set on the slide plate 802, and the main thread block 203 is moved to the farthest position close to the main motor 9. The slide plate 802 is moved to the farthest position close to the auxiliary motor 902. At this time, the upper sand box 5 hooked by the hook plate 405 and the lower sand box 6 at the top of the slide plate 802 are completely aligned and in a vertical state. At this time, the upper sand box 5 is placed on top of the lower sand box 6 by the hydraulic rod 205. The connection between the hook plate 405 and the fixing ring 501 is disconnected by the cylinder 301. Through the above technical solution, the misalignment of the upper sand box 5 and the lower sand box 6 is avoided, which would cause the dimensional deviation of the product after casting.

[0029] Specifically, a plurality of slides 8 are fixedly connected to the top of the outer surface of the base plate 1, and a slider 801 is slidably sleeved on the outer surface of each of the slides 8, and a slide plate 802 is fixedly connected to the top of the outer surface of each of the sliders 801.

[0030] Through the above technical solution, the slide plate 802 is slidably sleeved on the outside of the carriage 8 by multiple sliders 801.

[0031] Specifically, a threaded plate 7 is fixedly connected to the top of the outer surface of the base plate 1, and an auxiliary threaded rod 701 is rotatably embedded inside the threaded plate 7. An auxiliary threaded block 703 is threadedly sleeved on the outer surface of the auxiliary threaded rod 701. An auxiliary limiting rod 702 is provided inside the threaded plate 7. The auxiliary threaded block 703 is slidably sleeved on the outer surface of the auxiliary limiting rod 702. The auxiliary threaded block 703 is fixedly connected to the bottom of the outer surface of the slide plate 802.

[0032] Through the above technical solution, the auxiliary threaded rod 701 rotates, thereby driving the auxiliary threaded block 703 to move. The movement of the auxiliary threaded block 703 drives the slide plate 802 to move. The auxiliary limiting rod 702 limits the auxiliary threaded block 703.

[0033] Specifically, both sides of the outer surface of the push-pull plate 303 are fixedly connected to fixed posts 304, and large moving blocks 4 are rotatably sleeved on the outer surface of multiple fixed posts 304. First connecting rods 401 are rotatably embedded inside the multiple large moving blocks 4, and small moving blocks 402 are rotatably sleeved on the outer surface of multiple first connecting rods 401. Second moving blocks 403 are rotatably embedded inside the multiple small moving blocks 402, and multiple second moving blocks 403 are rotatably embedded inside the support arm 404.

[0034] With the above technical solution, when the push-pull plate 303 moves, the large moving block 4 is moved by the fixed column 304. The movement of the large moving block 4 drives the small moving block 402 connected by the first connecting rod 401 to move. The small moving block 402 is fixedly connected to the support arm 404 by the second moving block 403. The support arm 404 is rotatably sleeved on the fixed rod 406. The small moving block 402 pushes the support arm 404 to rotate around the fixed rod 406 as the center, so that multiple hook plates 405 pass through the fixed ring 501 at the top of the upper sand box 5.

[0035] Specifically, a main motor plate 901 is fixedly connected to one side of the outer surface of the thread box 2, and a main motor 9 is provided on the top of the outer surface of the main motor plate 901. The output shaft of the main motor 9 is fixedly connected to the main thread rod 201. Multiple back plates 101 are fixedly connected to the top of the outer surface of the base plate 1, and the multiple back plates 101 are all fixedly connected to one side of the outer surface of the thread box 2.

[0036] Through the above technical solution, the main motor 9 drives the main thread rod 201 to rotate, and the back plate 101 supports the thread box 2.

[0037] Specifically, an auxiliary motor plate 903 is fixedly connected to one side of the outer surface of the threaded plate 7, and an auxiliary motor 902 is provided on the top of the outer surface of the auxiliary motor plate 903. The output shaft of the auxiliary motor 902 is fixedly connected to the auxiliary threaded rod 701.

[0038] The above technical solution enables the auxiliary threaded rod 701 to rotate via the auxiliary motor 902.

[0039] Specifically, each of the outer surfaces of the multiple hook plates 405 is provided with a fixing ring 501, and the bottom of the outer surface of each of the multiple fixing rings 501 is fixedly connected with an upper sand box 5, and the top of the outer surface of the slide plate 802 is provided with a lower sand box 6.

[0040] Through the above technical solution, a fixing ring 501 is fixed on the top of the sand box 5, and the fixing ring 501 is placed on the top of the slide plate 802.

[0041] In use, by activating the cylinder 301 on the fixed plate 3, a telescopic column 302 is installed inside the cylinder 301. The telescopic column 302 extends and retracts, causing the push-pull plate 303 to move up and down. When the push-pull plate 303 moves, it drives the large moving block 4 to move through the fixed column 304. The movement of the large moving block 4 drives the connected small moving block 402 to move through the first connecting rod 401. The small moving block 402 is fixedly connected to the support arm 404 through the second moving block 403. The support arm 404 is rotatably sleeved on the fixed rod 406. The small moving block 402 pushes the support arm 404 around the fixed rod 406. The machine rotates, causing multiple hook plates 405 to pass through the fixing rings 501 at the top of the upper sand box 5. At this time, the telescopic column 302 retracts, and the support arm 404 moves inward as the telescopic column 302 retracts, thereby hooking the multiple fixing rings 501 onto the hook plates 405. Through the above technical solution, the upper sand box 5 is hooked and fixed, thus facilitating subsequent transportation and use. By default, the upper sand box 5 is hooked and fixed. By turning on the main motor 9 at the top of the main motor plate 901, the output shaft of the main motor 9 is fixedly connected to the main thread rod 201. The main motor 9 drives the main thread rod 201 to rotate, and the rotation of the main thread rod 201 drives the main thread block 20. 3. The main threaded block 203 moves, thereby driving the moving plate 204 to move. The moving plate 204 is connected to the fixed plate 3 through multiple hydraulic rods 205. Then, the auxiliary motor 902 on the top of the auxiliary motor plate 903 is turned on. The output shaft of the auxiliary motor 902 is fixedly connected to the auxiliary threaded rod 701. The auxiliary motor 902 drives the auxiliary threaded rod 701 to rotate. The rotation of the auxiliary threaded rod 701 drives the auxiliary threaded block 703 to move. The movement of the auxiliary threaded block 703 drives the slide plate 802 to move. The slide plate 802 is slidably sleeved on the outside of the slide frame 8 through multiple sliders 801. The movement of the slide plate 802 drives the lower sand box 6 to move. (Manual) Push the lower sand box 6 to fit the baffle set on the slide plate 802, move the main thread block 203 to the farthest position near the main motor 9, and move the slide plate 802 to the farthest position near the auxiliary motor 902. At this time, the upper sand box 5 hooked by the hook plate 405 and the lower sand box 6 at the top of the slide plate 802 are completely aligned and in a vertical state. Then, the upper sand box 5 is placed on top of the lower sand box 6 by the hydraulic rod 205, and the connection between the hook plate 405 and the fixing ring 501 is disconnected by the cylinder 301. Through the above technical solution, the misalignment of the upper sand box 5 and the lower sand box 6 is avoided, which would cause the dimensional deviation of the product after subsequent casting.
