Description

Technical Field

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

[0002] Mold steel is a high-alloy steel specifically designed for manufacturing molds. It possesses excellent strength, hardness, wear resistance, and toughness, making it widely used in various industrial sectors, such as plastic molding, metal stamping, and die casting. The unique properties of mold steel enable it to operate under high loads and dynamic conditions, ensuring production efficiency and the quality of finished molds. Because mold steel is typically heavy and comes in various shapes, ensuring its stable position during processing and transportation is crucial, necessitating the use of specialized lifting equipment to handle these heavy workpieces safely and efficiently.

[0003] In the process of developing this application, the inventors discovered the following problems with the existing technology: Conventional hoisting devices can generally only adjust the vertical direction of the mold steel during the production process, but cannot flexibly change its horizontal position. This may require operators to perform more manual handling and adjustment, thereby increasing labor intensity and reducing work efficiency. In addition, because the horizontal position of the mold steel cannot be effectively adjusted, the overall layout of the production line may be restricted, thus reducing the flexibility of the production process.

[0004] Therefore, those skilled in the art have provided a hoisting device for mold steel production to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hoisting device for mold steel production. This invention can stably clamp mold steel and adjust its horizontal and vertical positions as needed.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A hoisting device for mold steel production includes a mounting frame and a clamping mechanism. A stepped groove is fixedly provided on the upper end of the mounting frame, and a rack is fixedly provided on the upper end of the mounting frame near the edge.

[0008] The clamping mechanism includes a hydraulic telescopic rod, a fixed plate, and four movable clamping plates. A limiting plate is fixedly sleeved on the lower end of the outer side of the hydraulic telescopic rod. A No. 1 motor is fixedly installed at one corner of the upper end of the limiting plate. A No. 1 gear is fixedly sleeved on the output end of the No. 1 motor. An installation plate is fixedly installed at the lower end of the hydraulic telescopic rod. A hook is fixedly installed at the lower end of the installation plate.

[0009] A lifting ring is fixedly installed at the upper end of the fixed plate. Connecting rods are hinged around the four sides of the fixed plate. Movable plates are hinged at the lower ends of the four connecting rods. A second motor is fixedly installed at the lower edge of the movable plate. A drive gear is fixedly sleeved at the output end of the four second motors. Fixed columns are rotatably installed at the lower edge of the movable plate. Driven gears are fixedly sleeved at the upper outer side of the four fixed columns. Fixed clamping plates are rotatably installed at the lower ends of the four fixed columns.

[0010] Furthermore, the limiting plate is movably disposed at the inner end of the step groove, and the hydraulic telescopic rod passes through the step groove.

[0011] Furthermore, the first gear is meshed with the rack, and the mounting plate is movably disposed at the inner end of the mounting frame.

[0012] Furthermore, the lifting ring is placed outside the hook, and the hook is movably positioned at the lower end of the limiting plate.

[0013] Furthermore, the driving gear meshes with the driven gear, and the inner ends of the four movable clamps are rotatably equipped with internal threaded bearings.

[0014] Furthermore, the lower outer ends of the four fixed columns are threadedly connected to the internal thread bearings, and the four movable clamps are movably mounted on the upper ends of the four fixed clamps.

[0015] This utility model has the following beneficial effects:

[0016] This utility model proposes a hoisting device for mold steel production. After the lifting ring is hung on the hook, the mold steel to be processed is placed on the upper part of the fixed clamping plate. The second motor is started, and the driving gear meshes with the driven gear, causing the movable clamping plate to move towards the fixed clamping plate, thereby stably clamping the mold steel. Then, the first motor is started, and the first gear meshes with the rack, causing the position of the limiting plate to move within the stepped groove. The stepped groove has an upper diameter larger than the lower diameter, and the width of the limiting plate is the same as the upper diameter of the stepped groove, thus changing the horizontal position of the mold steel. After the inner rod of the hydraulic telescopic rod extends, the position of the lifting ring will drop, thereby adjusting the vertical position of the mold steel. Through automated clamping and positioning functions, this device can quickly adjust the mold steel to a suitable position, shorten the processing preparation time, and improve production efficiency. At the same time, the movable clamping plate and the fixed clamping plate effectively stabilize the mold steel, reduce movement and vibration during processing, and ensure processing accuracy and finished product quality.

A limiting plate 402 is fixedly sleeved on the lower end of the outer side of the hydraulic telescopic rod 401. A first motor 403 is fixedly installed on the upper end of the limiting plate 402 near one corner. A first gear 404 is fixedly sleeved on the output end of the first motor 403.

Driven gears 416 are fixedly sleeved on the upper outer side of each of the four fixed posts 413. Fixed clamping plates 415 are rotatably installed at the lower end of the four fixed posts 413. Limiting plate 402 is movably installed inside the stepped groove 2. Hydraulic telescopic rod 401 passes through the stepped groove 2. Gear 404 meshes with rack 3.

[0029] Specifically, after hanging the lifting ring 408 on the hook 406, the mold steel to be processed is placed on the upper end of the fixed clamping plate 415.

The upper diameter of the stepped groove 2 is larger than the lower diameter, and the width of the limiting plate 402 is the same as the upper diameter of the stepped groove 2. Therefore, the horizontal position of the mold steel can be changed. After the inner rod of the hydraulic telescopic rod 401 extends, the position of the lifting ring 408 will drop, thereby adjusting the vertical position of the mold steel.
