Technical Field
[0001] This utility model relates to the field of casting technology, specifically to a quick assembly and disassembly device for a cylindrical movable block. Background Technology
[0002] Casting is the process of pouring molten metal into a mold, cooling and solidifying it to obtain a part with the desired shape and properties. Simply put, it involves heating and melting metal, pouring it into a sand mold or casting mold, and then cooling and solidifying it to form a casting.
[0003] In the casting production process, core boxes are often used to make cores. Some large and medium-sized castings use core boxes with a large number of loose blocks. The traditional method of installing loose blocks is to use screws to tighten them. This installation method requires inserting each bolt into the corresponding hole, and then putting each nut on the corresponding bolt and tightening it. This consumes a lot of the physical strength and energy of the workers, resulting in low work efficiency. Utility Model Content
[0004] In view of the problems existing in the disassembly and assembly of the current core box, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide a quick assembly and disassembly device for cylindrical movable blocks, which solves the problem that the existing installation method of movable blocks requires each bolt to be inserted into the corresponding hole, and then each nut to be put on the corresponding bolt and tightened, which consumes a lot of physical strength and energy of the workers and leads to low work efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A quick-release device for a cylindrical movable block includes a first core box, a second core box located below the first core box, and multiple support columns symmetrically fixedly connected to the side walls of the second core box. Each support column has a groove at one end, and a connecting rod is rotatably connected inside each groove. A fixing rod is fixedly sleeved on the wall of each connecting rod. Two fixing plates are symmetrically fixedly connected to the outer surface of the first core box, and a slot is formed on one side of each fixing plate. Each fixing rod matches a corresponding slot, and a nut is threaded onto the wall of each fixing rod.
[0008] Preferably, one end of the second core box is provided with multiple positioning slots, and a first magnet is fixedly connected inside each positioning slot.
[0009] Preferably, one end of the first core box is fixedly connected with a plurality of second magnets, each of the second magnets being matched with a corresponding positioning groove and a first magnet.
[0010] Preferably, one end of each fixing rod is provided with a thread that matches the corresponding nut.
[0011] Preferably, a stop block is fixedly connected to one end of each of the fixed rods.
[0012] Preferably, both the first core box and the second core box are semi-cylindrical in shape.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] 1. In this utility model, by rotating each fixing rod and moving it into the corresponding slot, and then tightening each nut to press it against the corresponding fixing plate, the fixing rod can be fixed, that is, the first core box and the second core box can be fixed. When it is necessary to disassemble the first core box and the second core box, simply loosen each nut without completely unscrewing it, and then the two fixing rods can be rotated, and then the first core box and the second core box can be opened.
[0015] 2. In this utility model, each second magnet is inserted into the corresponding positioning groove. The second magnet can play a positioning role, so that the first core box and the second core box can be aligned. Then, each second magnet is attracted to the corresponding first magnet, so that the first core box and the second core box can be initially fixed and prevented from separating during the subsequent fixing process.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0023] This utility model discloses a quick assembly and disassembly device for a cylindrical movable block.
[0024] This utility model provides, for example Figure 1-3 The cylindrical movable block quick-release device shown includes a first core box 1, a second core box 2 is arranged below the first core box 1, a plurality of support columns 3 are symmetrically fixedly connected to the side wall of the second core box 2, a groove is opened at one end of each support column 3, a connecting rod 4 is rotatably connected inside each groove, a fixing rod 5 is fixedly sleeved on the rod wall of each connecting rod 4, two fixing plates 6 are symmetrically fixedly connected to the outer surface of the first core box 1, a slot is opened on one side of each of the two fixing plates 6, each fixing rod 5 is matched with the corresponding slot, and a nut 7 is threadedly sleeved on the rod wall of each fixing rod 5.
[0025] In use, align the first core box 1 and the second core box 2, then rotate each fixing rod 5 and move it into the corresponding slot. Then tighten each nut 7 and press it against the corresponding fixing plate 6, so that the fixing rod 5 can be fixed, that is, the first core box 1 and the second core box 2 can be fixed. When it is necessary to disassemble the first core box 1 and the second core box 2, simply loosen each nut 7, without completely unscrewing it, and then rotate the two fixing rods 5, and then the first core box 1 and the second core box 2 can be opened.
[0026] To facilitate the alignment and fixing of the first core box 1 and the second core box 2, as follows: Figure 1 As shown, one end of the second core box 2 is provided with multiple positioning slots, and a first magnet 8 is fixedly connected inside each positioning slot. One end of the first core box 1 is fixedly connected with multiple second magnets 9, and each second magnet 9 is matched with the corresponding positioning slot and the first magnet 8.
[0027] Each second magnet 9 is inserted into the corresponding positioning slot. Here, the second magnet 9 can play a positioning role, so that the first core box 1 and the second core box 2 can be aligned. Then, each second magnet 9 is attracted to the corresponding first magnet 8, so that the first core box 1 and the second core box 2 can be initially fixed together to prevent them from separating during the subsequent fixing process.
[0028] In order for nut 7 to be tightened, as follows Figure 1 As shown, one end of each of the fixing rods 5 is provided with a thread that matches the corresponding nut 7.
[0029] The thread allows the corresponding nut 7 to be tightened and secured.
[0030] To prevent nut 7 from being lost, such as Figure 1 As shown, a stop block 10 is fixedly connected to one end of each of the fixed rods 5.
[0031] The stop block 10 can be used to limit the movement, preventing the nut 7 from being removed from the wall of the fixing rod 5, thereby preventing the nut 7 from being lost.
[0032] To facilitate casting, such as Figure 1 As shown, both the first core box 1 and the second core box 2 are semi-cylindrical in shape.
[0033] The first core box 1 and the second core box 2 can be combined to form a complete column shape, which facilitates the forming of the casting.
