Description

Technical Field

[0001] This utility model relates to the field of lifting tools, and in particular to a mold heat treatment anti-deformation lifting tool. Background Technology

[0002] Lifting tools, in English, refer to devices used in lifting machinery to lift heavy objects. The most commonly used lifting tools for lifting packaged goods are hooks and slings; others include lifting rings, lifting suction cups, clamps, and forks. They are widely used in the lifting and hoisting industry, and are also necessary for clamping and lifting molds during heat treatment.

[0003] As shown in the reference case "A Lifting Fixture for Heat Treatment of Mold Steel" (Announcement No. CN221700951U), the clamping mechanism effectively and stably clamps the mold steel. After the mold steel is clamped and fixed, the moving component moves the mold steel to the front of the heating furnace. Then, the output end of the translation cylinder drives the fixed plate, base plate, fixed clamping plate, movable clamping plate, and mold steel towards the inner cavity of the heating furnace until the mold steel is moved into the heating furnace. The clamping component then releases the clamping of the mold steel, facilitating effective, stable, and safe heat treatment, lifting, and transportation of the mold steel, thus effectively improving the usage effect.

[0004] According to the above references, in the above device, the output end of the third servo motor drives the third lead screw to rotate, and the movable clamping plate on the outside of the third lead screw moves stably toward the fixed clamping plate. Thus, the fixed clamping plate and the movable clamping plate clamp and fix the mold steel. Moreover, the movable clamping plate and the fixed clamping plate are toothed on opposite sides, which effectively improves the clamping stability of the mold steel. However, when the device is used to lift the mold, the clamping effect of the fixed clamping plate and the movable clamping plate on molds of different shapes is not ideal. The mold is prone to deformation during heat treatment, which affects the use of the lifting device, makes it inconvenient to lift the lifting device stably, and reduces the use effect of the lifting device. Utility Model Content

[0005] Therefore, it is necessary to provide a mold heat-treated anti-deformation lifting tool to address the problem of inconvenience in stabilizing the lifting tool.

[0006] The device includes two sets of support rods, with two support rods in each set. The two sets of support rods are hinged together. An installation plate is mounted on the bottom end of each support rod. A lifting mechanism is provided on one side of the installation plate. The lifting mechanism includes a fixed plate slidably connected to one side of the inner wall of the installation plate. A clamping plate is hinged to one side of the fixed plate. Two ceramic springs are fixedly connected to one side of the clamping plate. The other end of each ceramic spring is fixedly connected to the fixed plate. A replacement assembly is mounted on the top of the installation plate.

[0007] In one embodiment, the hoisting mechanism further includes a threaded rod threaded to the other side of the mounting plate, one end of which passes through the mounting plate and is rotatably connected to the fixed plate.

[0008] In one embodiment, two guide rods are fixedly connected to one side of the fixing plate, and the guide rods are slidably connected to the inner wall of the mounting plate.

[0009] In one embodiment, the two guide rods are respectively disposed on both sides of the threaded rod.

[0010] In one embodiment, a limiting plate is fixedly connected to the other side of the clamp.

[0011] In one embodiment, the replacement component includes a locking block fixedly connected to the top of the mounting plate, and the bottom end of the support rod has a locking groove that engages with the locking block.

[0012] In one embodiment, a fixing bolt is rotatably connected to one side of the support rod, and one end of the fixing bolt passes through the support rod and is threaded to the top of the locking block.

[0013] In one embodiment, a limiting rod is fitted onto the outer wall of the fixing bolt, and the bottom end of the limiting rod passes through the support rod and extends to the bottom of one side of the locking block.

[0014] Beneficial effects 1. The above-mentioned mold heat treatment anti-deformation lifting device has a clamping plate hinged to the other side of the fixed plate, which can rotate up and down. In conjunction with two ceramic springs, it can limit and support the upper and lower ends of the clamping plate, keeping it in a centered position. By contacting the surface of the lifting device, the clamping plate can automatically adjust and fit, which can avoid stress concentration and prevent the mold from deforming during heat treatment. The limiting plate on the other side of the clamping plate can reduce the wear of the clamping plate on the mold. The threaded rod cooperates with the mounting plate to adjust the position of the clamping plate. The clamping force of the lifting device can be adjusted according to the size of the mold. The two guide rods can limit and support the fixed plate, improve the stability of the fixed plate, and adjust the clamping plate according to the shape and size of the mold to stably lift the mold and prevent the mold from deforming. 2. When hoisting the mold, the mounting plate 200 uses a locking block and a locking slot. Both the locking block and the locking slot are T-shaped structures, which allows for quick installation and disassembly of the clamping plate. The clamping plate can be replaced according to different molds, which can improve the use of the lifting tool. The fixing bolts cooperate with the locking block to fix the locking block inside the support rod. When the fixing bolts are installed, one end of the limit rod is inserted into the locking block to reinforce the mounting plate, which facilitates the replacement of the clamping plate and improves the hoisting effect of the lifting tool on the mold.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined with Figure 1 - Figure 5 This invention describes a mold heat treatment anti-deformation lifting device.

[0020] In one embodiment, a mold heat treatment anti-deformation lifting device includes two sets of support rods 100, each set of support rods 100 having two members, and the two sets of support rods 100 being hinged to each other. An installation plate 200 is installed at the bottom end of the support rods 100, and a lifting mechanism 300 is provided on one side of the installation plate 200. The lifting mechanism 300 includes a fixing plate 310 slidably connected to one side of the inner wall of the installation plate 200. A clamping plate 320 is hinged to one side of the fixing plate 310, and two ceramic springs 330 are fixedly connected to one side of the clamping plate 320. The other end of the ceramic springs 330 is fixedly connected to the fixing plate 310. A replacement assembly 370 is installed at the top of the installation plate 200.

[0021] It should be noted that the lifting device with model number "5~100T" is mainly composed of a support component and a clamping arm. The clamping arm is connected to the support component through a pivot pin. The opening and closing mechanism usually includes components such as a connecting plate and a synchronizer, which are used to control the clamping and releasing actions. The opening and closing mechanism allows the clamping surface at one end of the lifting device to contact the workpiece, and the lifting eye at the other end is used to connect the lifting device. When the mold is lifted for heat treatment, the lifting mechanism 300 rotates up and down in cooperation with the ceramic spring 330 through the clamping plate 320 on one side of the mounting plate 200, so that the clamping plate 320 and the limiting plate 360 ​​are in contact with the surface of the mold, and the mold is stably clamped. The position of the clamping plate 320 can be adjusted and controlled by the threaded rod 340. The replacement component 370 can replace the clamping plate 320 according to different molds through the locking block 371 and the locking slot 372. The lifting mechanism 300 and the replacement component 370 can optimize the lifting effect of the lifting device, prevent mold deformation, and not affect the normal use of the lifting device.

[0022] like Figure 2 and Figure 3 As shown, the hoisting mechanism 300 also includes a threaded rod 340 threadedly connected to the other side of the mounting plate 200. One end of the threaded rod 340 passes through the mounting plate 200 and is rotatably connected to the fixing plate 310. Two guide rods 350 are fixedly connected to one side of the fixing plate 310. The guide rods 350 are slidably connected to the inner wall of the mounting plate 200. The two guide rods 350 are respectively arranged on both sides of the threaded rod 340. A limit plate 360 ​​is fixedly connected to the other side of the clamping plate 320.

[0023] In this embodiment, when the clamping plate 320 contacts the surface of the mold, the clamping plate 320 rotates according to the surface of the mold to fit against the surface of the mold. Then, two ceramic springs 330 support the upper and lower ends of the clamping plate 320 to improve the stability of the clamping plate 320. The clamping plate 320 drives the limiting plate 360 ​​to contact the mold, reducing the wear caused by clamping on the mold. The threaded rod 340 is threadedly connected to the mounting plate 200, which can drive the clamping plate 320 on one side of the fixed plate 310 to move to one side, adjusting the clamping force of the clamping plate 320. The two guide rods 350 move to one side with the fixed plate 310 to limit and support the fixed plate 310, improving the stability of the fixed plate 310. It can fit against the surface of the mold to avoid stress concentration and prevent the mold from deforming during heat treatment. The lifting device can stably lift the mold.

[0024] like Figure 4 and Figure 5 As shown, the replacement component 370 includes a locking block 371 fixedly connected to the top of the mounting plate 200. The bottom end of the support rod 100 has a locking groove 372 that fits into the locking block 371. A fixing bolt 373 is rotatably connected to one side of the support rod 100. One end of the fixing bolt 373 passes through the support rod 100 and is threaded to the top of one side of the locking block 371. A limiting rod 374 is sleeved on the outer wall of the fixing bolt 373. The bottom end of the limiting rod 374 passes through the support rod 100 and extends to the bottom of one side of the locking block 371.

[0025] In this embodiment, when replacing the clamping plate 320, the fixing bolt 373 is rotated to move it to one side and remove it from the clamping block 371, thereby releasing the restriction on the clamping block 371 and the limiting rod 374. One end of the limiting rod 374 is then removed from the clamping block 371, allowing the clamping block 371 to be removed from the slot 372. This allows the mounting plate 200 to be replaced, improving the lifting effect of the lifting device on the mold and preventing deformation of the mold during heat treatment.

[0026] Working principle: The lifting device moves to the upper surface of the mold via the top lifting ring, ensuring the opening and closing mechanism of the lifting device operates to clamp the workpiece. Two sets of support rods 100 amplify the weight of the lifted object through leverage, generating clamping force to fix the mold. The support rods 100 drive the clamping plate 320 to fix the workpiece. The clamping plate 320 contacts the surface of the mold and rotates up and down according to the mold's surface. Two ceramic springs 330 provide limiting support to the clamping plate 320 through their own elasticity. The threaded rod 340 can be manually rotated... The threaded connection of the mounting plate 200 can move one side of the fixing plate 310 to adjust the position of the clamping plate 320. The two guide rods 350 limit the fixing plate 310 when the threaded rod 340 rotates. When hoisting molds of different shapes, the fixing bolt 373 is manually rotated to move to one side through the threaded connection with the locking block 371, thus contacting the limitation of the limiting rod 374. The limiting rod 374 can then move to one side to contact the limitation of the locking block 371. The locking block 371 can be removed from the slot 372, and the clamping plate 320 can be replaced.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
