Description

Technical Field

[0001] This utility model relates to the field of mold steel production technology, specifically to a hoisting device for mold steel production. Background Technology

[0002] Mold steel is a type of steel used to manufacture molds such as cold stamping dies, hot forging dies, and die casting molds. Mold materials are the material and technological foundation of the mold manufacturing industry. Among them, mold steel is a traditional mold material, and its variety, specifications, and quality play a decisive role in the performance, service life, and manufacturing cycle of the mold.

[0003] A search revealed Chinese Patent Publication No. CN219751683U, which discloses a hoisting device for mold steel production. The device includes a hoisting frame with support frames fixedly mounted at both ends of its bottom. A snap-fit ​​frame slides on the hoisting frame, and a winch is mounted at the bottom of the snap-fit ​​frame. A wire rope is mounted on the winch, and an installation assembly is detachably connected to the bottom of the wire rope. The installation assembly includes four diagonal support columns, each with a cross-shaped frame fixedly connected to its bottom. The cross-shaped frame has four internal cavities, and each of the four internal cavity walls is rotatably connected to a lead screw. Each of the four lead screws is threaded with a moving block. Each of the four movable blocks has a fixed support column at its bottom, and each of the four support columns has a fixed base plate at its bottom. By rotating the rotating wheel, the lead screw is driven to rotate, which in turn drives the movable blocks to move. The movable blocks then drive the support columns and base plates to move, adjusting the position of the four clamping components to match the size of the mold steel, thus facilitating the clamping of mold steel of different sizes. In this utility model, the lower surface of the base is fixed with pulleys. When using a lifting frame to lift the mold steel, the stability of the lifting frame is not good. If it is accidentally touched, the lifting frame will be displaced, requiring readjustment of the lifting frame's position, which reduces the lifting efficiency of the mold steel. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hoisting device for mold steel production, which has advantages such as the ability to switch between the moving or active states of the hoisting frame. It solves the problem that when using a hoisting frame to hoist mold steel, the stability of the hoisting frame is poor due to the fixed pulleys on the lower surface of the base. Accidental contact can cause the hoisting frame to shift, requiring readjustment of the hoisting frame's position and thus reducing the hoisting efficiency of the mold steel.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hoisting device for mold steel production, comprising a hoisting frame, a winch fixed at the center of the inner top wall of the hoisting frame, a hook fixed at the other end of the winch rope, support plates fixed at both ends of the lower surface of the hoisting frame, casters fixed at both the front and rear sides of the lower surface of the support plates, a stabilizing mechanism for improving the stability of the hoisting frame during hoisting provided at the middle of the opposite side of the two support plates, and a fixing mechanism for positioning mold steel of different sizes provided on the lower side of the hook; The stabilizing mechanism includes a protective box fixed in the middle of the opposite side of two support plates. A drive motor is fixed inside the protective box. The output shaft of the drive motor passes through the support plate and extends into the inner cavity of the support plate, and a first rotating rod is fixed thereon. A second rotating rod is rotatably connected between the rear ends of the opposite sides of the left and right side walls of the inner cavity of the support plate via bearings. Rotating gears are fixed in the middle of the outer surfaces of the first and second rotating rods. Gear plates are meshed on the opposite sides of the two rotating gears. A drive plate is fixed on the upper surface of the gear plate. The left and right sides of the drive plate pass through the left and right side walls of the inner cavity of the support plate and extend into the left and right sides of the support plate, respectively. Support seats are fixed at both ends of the lower surface of the drive plate.

[0006] Furthermore, both ends of the first rotating rod are rotatably connected to the opposite sides of the left and right side walls of the inner cavity of the support plate via bearings, and the first rotating rod and the second rotating rod are connected by belt drive.

[0007] Furthermore, telescopic rods are fixed at both ends of the inner bottom wall of the drive plate and the support plate on opposite sides, and the two telescopic rods are nested fixed rods and inner rods.

[0008] Furthermore, through holes are provided on the opposite sides of the left and right side walls of the inner cavity of the support plate, and the size of the inner cavity of the through holes is adapted to the size of the drive plate.

[0009] Furthermore, the fixing mechanism includes a mounting plate located on the lower side of the hook. A first cavity is formed at the bottom between the opposite sides of the left and right side walls of the inner cavity of the mounting plate. A second cavity is formed at the top between the opposite sides of the front and rear side walls of the inner cavity of the mounting plate. A bidirectional screw is rotatably connected between the opposite sides of the left and right side walls of the first cavity and between the opposite sides of the front and rear side walls of the second cavity via bearings.

[0010] Furthermore, one end of the bidirectional screw passes through and extends to the outside of the mounting plate, the mounting plate has a square cross-sectional shape, and anti-slip pads are fixed on the opposite sides of the positioning plate and the pressure plate, the anti-slip pads being rubber pads.

[0011] Furthermore, slide bars are fixed to the left and right ends of the top wall of the first cavity and the front and rear ends of the top wall of the second cavity. A slider is fixed to the upper surface of the screw sleeve. The size of the slider is adapted to the size of the inner cavity of the slide bar. The four screw sleeves are symmetrically distributed on the left and right ends and the front and rear sides of the vertical central axis of the two bidirectional screws.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. The hoisting device for mold steel production, through the stabilizing mechanism, enables the bottom of the support base to contact the ground and the casters to separate from the ground through the cooperation between the various structures.

[0013] 2. The hoisting device for mold steel production can position all four sides of the mold steel through the fixed mechanism. After the mold steel is positioned, the spring telescopic rod will be squeezed, which will generate a downward force and push the pressure plate to squeeze the mold steel, thereby positioning the top of the mold steel. In use, only two double-acting screws need to be rotated, which reduces the labor intensity of the workers. Attached Figure Description

[0016] 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.

[0017] Please see Figure 1 This embodiment of a hoisting device for producing mold steel includes a hoisting frame 1. A winch 2 is fixed at the center of the inner top wall of the hoisting frame 1. A hook 3 is fixed at the other end of the rope of the winch 2. Support plates 4 are fixed at both ends of the lower surface of the hoisting frame 1. Universal wheels 5 are fixed on both the front and rear sides of the lower surface of the support plates 4. A stabilizing mechanism 6 is provided in the middle of the opposite side of the two support plates 4 to improve the stability of the hoisting frame 1 during hoisting. A fixing mechanism 7 is provided on the lower side of the hook 3 to position mold steel of different sizes.

[0018] Please see Figures 2 to 3 To improve the stability of the hoisting frame 1 during hoisting, the stabilizing mechanism 6 in this embodiment includes a protective box 601 fixed in the middle of the opposite side of the two support plates 4. A drive motor 602 is fixed in the inner cavity of the protective box 601. The output shaft of the drive motor 602 passes through the support plate 4 and extends into the inner cavity of the support plate 4, and a first rotating rod 603 is fixed thereon. A second rotating rod is rotatably connected between the rear ends of the left and right side walls of the inner cavity of the support plate 4 through bearings. A rotating gear 604 is fixed in the middle of the outer surface of both the first rotating rod 603 and the second rotating rod. When the drive motor 602 is started, the output shaft of the drive motor 602 rotates, driving the first rotating rod 603 to rotate. The rotation of the first rotating rod 603 can cause the second rotating rod to rotate through belt transmission. The rotation of the two rotating rods causes the rotating gear 604 fixed on their outer surface to rotate.

[0019] Two rotating gears 604 are meshed with toothed plates 605 on opposite sides. A drive plate 606 is fixed on the upper surface of the toothed plate 605. The rotation of the rotating gears 604 causes the meshed toothed plates 605 to move downward. The movement of the toothed plates 605 drives the drive plate 606 to move downward. The left and right sides of the drive plate 606 pass through the left and right side walls of the inner cavity of the support plate 4 and extend to the left and right sides of the support plate 4, respectively. Support seats 607 are fixed at both ends of the lower surface of the drive plate 606. The movement of the drive plate 606 drives the support seats 607 on its lower surface to move until the bottom of the support seats 607 contacts the ground and the caster 5 is separated from the ground. Thus, the support seats 607 can be used to support the hoisting frame 1, thereby improving the stability of the hoisting frame 1 during hoisting.

[0020] The first rotating rod 603 is rotatably connected to the opposite side of the left and right side walls of the inner cavity of the support plate 4 via bearings at both ends. The first rotating rod 603 and the second rotating rod are connected by belt drive. The drive plate 606 is fixed with telescopic rods at both ends of the opposite side of the inner bottom wall of the support plate 4. The two telescopic rods are nested fixed rods and inner rods. The movement of the drive plate 606 causes the two telescopic rods to shorten, thereby limiting the movement of the drive plate 606.

[0021] In this embodiment, through holes are provided on the opposite sides of the left and right side walls of the inner cavity of the support plate 4, and the size of the inner cavity of the through holes is adapted to the size of the drive plate 606.

[0022] It should be noted that the stabilizing mechanism 6 can improve the stability of the lifting frame 1 during hoisting, making it easier for staff to switch the state of the lifting frame 1, thereby improving the hoisting efficiency of the mold steel.

[0023] Please see Figure 4 To reduce the labor intensity of workers, the fixing mechanism 7 in this embodiment includes a mounting plate 701 located below the hook 3. A first cavity 702 is formed at the bottom between the opposite sides of the left and right side walls of the inner cavity of the mounting plate 701. A second cavity 703 is formed at the top between the opposite sides of the front and rear side walls of the inner cavity of the mounting plate 701. A bidirectional screw 704 is rotatably connected via bearings between the opposite sides of the left and right side walls of the first cavity 702 and between the opposite sides of the front and rear side walls of the second cavity 703. Two threaded sleeves 705 are threaded onto the outer surface of the bidirectional screw 704. The mold steel is placed directly below the mounting plate 701, and then the bidirectional screw 704 is rotated. The rotation of the bidirectional screw 704 causes… Two threaded sleeves 705 on its surface are movable. A positioning plate 706 with one end penetrating and extending to the lower side of the mounting plate 701 is fixed on the lower surface of the threaded sleeves 705. The movement of the threaded sleeves 705 drives the positioning plate 706 to move, so that the positioning plates 706 at the left and right ends move relative to each other, and the positioning plates 706 at the front and rear ends move relative to each other, so that the four sides of the mold steel can be positioned. Three spring telescopic rods 707 are fixed in the middle of the lower surface of the mounting plate 701. A pressure plate 708 is fixed on the lower surface of the spring telescopic rods 707. After the mold steel is positioned, the spring telescopic rods 707 will be squeezed, thereby generating a downward force, which can push the pressure plate 708 to move downward, thereby positioning the top of the mold steel.

[0024] One end of the bidirectional screw 704 passes through and extends to the outside of the mounting plate 701. The mounting plate 701 has a square cross-section. Anti-slip pads are fixed on the opposite sides of the positioning plate 706 and the pressure plate 708. The anti-slip pads are rubber pads.

[0025] In this embodiment, slide bars are fixed at both ends of the top wall of cavity 702 and at both ends of the top wall of cavity 703. A slider is fixed on the upper surface of the screw sleeve 705. The size of the slider is adapted to the size of the inner cavity of the slide bar. The four screw sleeves 705 are symmetrically distributed at both ends of the vertical central axis of the two bidirectional screws 704 and at both ends of the left and right and front and rear sides.

[0026] It should be noted that the fixing mechanism 7 only requires rotating two bidirectional screws 704 to position the four sides of the mold steel, reducing the labor intensity of the workers.

[0027] The working principle of the above embodiments is as follows: (1) In order to improve the stability of the hoisting frame 1 when hoisting mold steel, the drive motor 602 can be started. The output shaft of the drive motor 602 rotates and drives the first rotating rod 603 to rotate. The rotation of the first rotating rod 603 can drive the second rotating rod to rotate through the belt drive. The rotation of the two rotating rods causes the rotating gear 604 fixed on its outer surface to rotate. The rotation of the rotating gear 604 causes the toothed plate 605 meshing with it to move downward. The movement of the toothed plate 605 drives the drive plate 606 to move downward. The movement of the drive plate 606 causes the two telescopic rods to shorten, thereby limiting the movement of the drive plate 606. The movement of the drive plate 606 drives the support seat 607 on its lower surface to move until the bottom of the support seat 607 contacts the ground and the caster 5 is separated from the ground. Thus, the support seat 607 can be used to support the hoisting frame 1, thereby improving the stability of the hoisting frame 1 during hoisting.

[0028] (2) When positioning the mold steel, the rope of the winch 2 can be extended to place the mold steel directly under the mounting plate 701. Then, the double-acting screw 704 is rotated. The rotation of the double-acting screw 704 causes the two threaded sleeves 705 connected to its surface to move. The threaded sleeves 705 can only move in a straight line under the action of the slide bar and the slider. The movement of the threaded sleeves 705 drives the positioning plate 706 to move, so that the positioning plates 706 at the left and right ends move relative to each other, and the positioning plates 706 at the front and rear ends move relative to each other. The four sides of the mold steel can be positioned. After the mold steel is positioned, the spring telescopic rod 707 is squeezed, which generates a downward force and can push the pressure plate 708 to move downward, thereby positioning the top of the mold steel.
