Technical Field
[0001] This utility model relates to the field of casting technology, specifically to a casting sand box. Background Technology
[0002] Sand boxes are an important piece of equipment in casting production, used for making and transporting sand molds. Sand boxes for manual molding generally have simpler requirements, while those for machine molding have more stringent requirements. In recent years, the widespread use of high-efficiency, high-pressure molding equipment such as high-pressure and air-jet molding has placed increasingly higher demands on sand boxes. Sand boxes are classified according to their manufacturing method into integral casting, assembled, and welded types. Commonly used sand box materials include cast iron, cast steel, cast aluminum, and steel plates. The structural form and material dimensions of the sand box should be determined based on the size of the casting, the molding method, the molding equipment, and the production batch size.
[0003] In the process of using existing sand boxes, workers need to flip the sand box and place the upper mold on the lower mold. This is usually done by workers manually lifting the sand box. However, because the sand box is filled with sand and molds, it is not easy to move and flip the sand box. The operation is quite strenuous and may easily injure the workers' legs and feet. Therefore, a new type of sand box for casting is proposed. Utility Model Content
[0004] To address the problems in the existing technology, this utility model provides a sand box for casting.
[0005] The technical solution adopted by this utility model to solve its technical problem is a casting sand box, including a first vertical plate, a second vertical plate and a sand box body. The first vertical plate and the second vertical plate are respectively provided with a first sliding groove and a second sliding groove on the side that are close to each other. A first lead screw is rotatably installed inside the first sliding groove, and a guide rod is provided inside the second sliding groove. A first slider is sleeved on the outside of the first lead screw and the guide rod.
[0006] Each of the two first sliders has a plug mounted on one side that is close to each other. A bearing is sleeved on the outside of the plug and installed inside the first slider. Slots are provided on opposite sides of the sand box body for the plug to be inserted.
[0007] By adopting the above technical solution, the device drives the first lead screw to rotate through the first motor, which in turn drives the first slider to rise along the first slide groove. The sand box body is lifted to the required height by the cooperation of the insert block and the slot. At the same time, the bearing design on the outside of the insert block allows the sand box body to rotate freely after being lifted, which is convenient for workers to perform flipping operations, greatly reducing the physical consumption of manual handling and adjustment, and improving the efficiency of casting operations.
[0008] Specifically, a cavity is provided on the upper part of one side of the first vertical plate, and a first motor is fixedly installed inside the cavity. The output end of the first motor is fixedly connected to one end of the first lead screw.
[0009] By adopting the above technical solution, the first motor can be started to drive the first slider to rise, thereby enabling the first slider to lift the sand box body.
[0010] Specifically, the bottom end of the first slider has a groove, and a threaded rod is installed on the inner side of the groove by thread, and the threaded rod is located directly above the insert block.
[0011] Specifically, threaded holes are provided on both opposite sides of the sand box body, and the threaded holes are adapted to the threads of the threaded rod.
[0012] By adopting the above technical solution, the threaded rod is screwed into the threaded holes on both sides of the sand box body, thereby fixing the first slider to the sand box body to ensure stability during transportation.
[0013] Specifically, the top end of the first vertical plate is fixedly connected to the bottom end of the horizontal plate, the bottom end face of the horizontal plate is provided with a third sliding groove, the inside of the third sliding groove is provided with a second lead screw, the outside of the second lead screw is sleeved with a second slider, and the bottom end of the second slider is fixedly connected to the top end of the second vertical plate.
[0014] Specifically, a second motor is fixedly installed at one end of the horizontal plate, and the output end of the second motor is fixedly connected to one end of the second lead screw.
[0015] By adopting the above technical solution, the motor can drive the second vertical plate to move closer to the first vertical plate, thereby allowing the insert block on one side of the first slider inside the second vertical plate to be inserted into the slot on the other side of the sand box body.
[0016] Specifically, both the bottom ends of the first and second vertical plates are equipped with omnidirectional pulleys, and multiple sets of omnidirectional pulleys are provided.
[0017] By adopting the above technical solution, the installation of universal pulleys allows the first and second vertical plates to move the sand box body.
[0018] The beneficial effects of this utility model are:
[0019] (1) The casting sand box of the present invention is driven by a first motor to rotate a first lead screw, which drives a first slider to rise along a first slide groove. The sand box body is lifted to the required height by the cooperation of the insert block and the slot. At the same time, the bearing design on the outside of the insert block allows the sand box body to rotate freely after being lifted, which is convenient for workers to perform flipping operations, greatly reduces the physical consumption of manual handling and adjustment, and improves the efficiency of casting operations.
[0020] (2) The casting sand box of this utility model adopts the cooperation of threaded rod and threaded hole on the side of the sand box body. The first slider is rigidly connected to the sand box body by manual tightening, which effectively prevents shaking or falling off due to the shift of the center of gravity during transportation.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0027] As one embodiment of this utility model, such as Figures 1-3 As shown, the casting sand box of this utility model includes a first vertical plate 1, a second vertical plate 10 and a sand box body 21. The first vertical plate 1 and the second vertical plate 10 are respectively provided with a first sliding groove 6 and a second sliding groove 18 on their sides that are close to each other. A first lead screw 7 is rotatably installed inside the first sliding groove 6. A guide rod 16 is provided inside the second sliding groove 18. A first slider 3 is sleeved on the outside of both the first lead screw 7 and the guide rod 16.
[0028] Both of the first sliders 3 are rotatably mounted with insert blocks 2 on their sides that are close to each other. A bearing 17 is sleeved on the outside of the insert block 2 and the bearing 17 is installed inside the first slider 3. Slots 20 are provided on both opposite sides of the sand box body 21. The slots 20 are used for inserting the insert blocks 2.
[0029] In use, the first vertical plate 1 and the second vertical plate 10 are pushed to the sides of the sand box body 21. By inserting the inserts 2 installed in the first sliders 3 on both sides of the first vertical plate 1 and the second vertical plate 10 into the slots 20 opened on both sides of the sand box body 21, the inserts 2 can drive the sand box body 21 to be lifted and flipped.
[0030] It should be noted that during the lifting process, the sand box body 21 needs to be supported by hand to prevent the sand box body 21 from tipping over due to the shift of the center of gravity.
[0031] The present invention also includes a cavity 13 formed on the upper part of one side of the first vertical plate 1, and a first motor 8 is fixedly installed inside the cavity 13. The output end of the first motor 8 is fixedly connected to one end of the first lead screw 7.
[0032] When in use, starting the first motor 8 can drive the first lead screw 7 to rotate. The rotation of the first lead screw 7 can drive the first slider 3 to move upward. Since the inserts 2 on one side of the two first sliders 3 are inserted into the slots 20 on both sides of the sand box body 21, the two first sliders 3 can lift the sand box body 21 to a certain height. With the setting of the bearing 17, the inserts 2 can rotate freely, which allows the workers to flip the sand box body 21.
[0033] The present invention also includes a groove 5 at the bottom end of the first slider 3, and a threaded rod 4 is threadedly installed on the inner side of the groove 5, the threaded rod 4 being located directly above the insert block 2.
[0034] This utility model also includes threaded holes 22 on both opposite sides of the sand box body 21, and the threaded holes 22 are threadedly adapted to the threaded rod 4.
[0035] When in use, screw the threaded rod 4 so that the end of the threaded rod 4 is screwed into the threaded holes 22 on both sides of the sand box body 21, thereby fixing the first slider 3 to the sand box body 21 to ensure stability during transportation.
[0036] The present invention further includes that the top end of the first vertical plate 1 is fixedly connected to the bottom end of the horizontal plate 12, the bottom end surface of the horizontal plate 12 is provided with a third sliding groove 19, the interior of the third sliding groove 19 is provided with a second lead screw 14, the outer side of the second lead screw 14 is sleeved with a second slider 15, and the bottom end of the second slider 15 is fixedly connected to the top end of the second vertical plate 10.
[0037] This utility model also includes a second motor 11 fixedly installed at one end of the horizontal plate 12, and the output end of the second motor 11 is fixedly connected to one end of the second lead screw 14.
[0038] When in use, the second motor 11 is started, and the second motor 11 drives the second lead screw 14 to rotate. The rotation of the second lead screw 14 can drive the second slider 15 to make linear motion in the third slide groove 19, so that the second slider 15 can drive the second vertical plate 10 to move closer to the first vertical plate 1. This allows the insert 2 on one side of the first slider 3 inside the second vertical plate 10 to be inserted into the slot 20 on the other side of the sand box body 21.
[0039] This utility model also includes that the bottom ends of the first vertical plate 1 and the second vertical plate 10 are provided with universal pulleys 9, and the universal pulleys 9 are provided in multiple sets.
[0040] In use, the universal pulleys 9 allow the first vertical plate 1 and the second vertical plate 10 to move the sand box body 21.
[0041] In use, the first vertical plate 1 and the second vertical plate 10 are first pushed to the sides of the sand box body 21 via the universal pulley 9. Then, the first vertical plate 1 is pushed so that the insert 2 on one side of the first slider 3 inside the first vertical plate 1 is inserted into the slot 20 on one side of the sand box body 21. Then, the second motor 11 is started, and the second motor 11 drives the second lead screw 14 to rotate. The rotation of the second lead screw 14 can drive the second slider 15 to move linearly in the third slide groove 19, so that the second slider 15 can drive the second vertical plate 10 to move closer to the first vertical plate 1. This allows the insert 2 on one side of the first slider 3 inside the second vertical plate 10 to be inserted into the slot 20 on the other side of the sand box body 21. Then, the first motor 8 is started, and the first motor 8 drives the first lead screw 7 to rotate. The rotation of the screw rod 7 can drive the first slider 3 to move upward. Since the inserts 2 on one side of the two first sliders 3 are inserted into the slots 20 on both sides of the sand box body 21, the two first sliders 3 can lift the sand box body 21 to a certain height. With the setting of the bearing 17, the inserts 2 can rotate freely, allowing the workers to flip the sand box body 21. When it is necessary to move the sand box body 21, simply turn the threaded rod 4 so that the end of the threaded rod 4 is screwed into the threaded holes 22 on both sides of the sand box body 21. This can fix the first slider 3 to the sand box body 21 to ensure stability during the moving process. Then, the first vertical plate 1 and the second vertical plate 10 can be pushed by the universal pulley 9 to complete the moving of the sand box body 21.
