Description

Technical Field

[0001] This utility model relates to the field of metal casting technology, and in particular to a metal casting clamping device. Background Technology

[0002] Metal casting, as one of the fundamental processes of modern industry, has a long history and wide applications. In today's global manufacturing landscape, the metal casting industry occupies an extremely important position. From heavy industries such as automobiles, aerospace, and machinery manufacturing, to light industries such as electronics, medical devices, and hardware products, metal castings are indispensable key components. With the continuous growth of the global economy and the accelerated pace of industrialization, the metal casting industry has also shown a vigorous development trend. A search revealed a metal casting clamping device (publication number: CN222020640U). This device directly installs the clamping mechanism on the side of the casting housing, allowing the metal casting to be directly removed from the casting cavity after casting by controlling the clamping mechanism and handle. This simplifies the clamping process, improves clamping efficiency, and does not interfere with the shape of the cast metal casting. However, it has drawbacks: there is a gap between the clamping mechanism and the housing, causing the casting liquid to leak along the gap during casting, affecting the molding quality and usability of the metal casting. Furthermore, the clamping mechanism participates in the mold forming process, which may lead to adhesion between the clamping mechanism and the metal casting, ultimately causing damage to the surface of the metal casting when it is removed. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a metal casting clamping device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A metal casting clamping device includes an operating table with a groove on it. A through slot is formed in the groove. Two sets of plates are slidably connected to the groove. A first screw is rotatably connected to the groove. A first guide rod is installed in the groove. One set of plates is threadedly connected to the first screw, and the other set of plates is slidably connected to the first guide rod. A first motor is mounted on the operating table, with its output end connected to the first screw. A second motor is mounted on one set of plates. Frames are rotatably connected to both sets of plates. The output end of the second motor is connected to one set of frames. A second screw is rotatably connected to one set of frames. A second guide rod is mounted on the other set of frames. Two sets of sleeves are threadedly connected to the second screw. The remaining sleeves are slidably connected to the second guide rod. Corresponding curved plates are mounted on the multiple sets of sleeves. Pressure-relieving plates are slidably connected to both sets of curved plates. Multiple sets of springs are connected between the pressure-relieving plates and the corresponding curved plates.

[0006] Preferably, a water tank is provided under the operating table.

[0007] Preferably, a handwheel is installed at one end of the second screw.

[0008] Preferably, the operating platform is equipped with two sets of support plates. One set of support plates is equipped with a hydraulic cylinder, the output end of which is connected to a set of molds. The other set of molds is connected to the other set of support plates.

[0009] Preferably, multiple sets of support rods are installed under the operating table.

[0010] Preferably, the water tank is provided with a hand gripping groove.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figures 1 to 5 A metal casting clamping device includes an operating table 1, a groove 2 on the operating table 1, a through groove 3 on the groove 2, two sets of plates 4 slidably connected to the groove 2, a first screw 5 rotatably connected inside the groove 2, a first guide rod 6 installed inside the groove 2, one set of plates 4 threadedly connected to the first screw 5, and the other set of plates 4 slidably connected to the first guide rod 6. A first motor 7 is installed on the operating table 1, the model of which is selected according to actual working requirements, and the output end of the first motor 7 is connected to the first screw 5. A second motor 8 is installed on one set of plates 4, the model of which is selected according to actual working requirements. Each set of plate 4 is rotatably connected to a frame 9. The output end of the second motor 8 is connected to one set of frame 9. A second screw 10 is rotatably connected to one set of frame 9. The first motor 7 drives the first screw 5 to rotate and cooperates with the first guide rod 6 to make the plates 4 on both sides slide in the groove 2 to the opening position of the mold 19. By turning the handwheel 17, the corresponding sleeve 12 and the opposite curved plate 13 are relatively displaced, so that the pressure relief plate 14 can take out the cast part that has been poured out from the clamp in the mold 19. A second guide rod 11 is installed on another set of frame 9. Two sets of sleeves 12 are threadedly connected to the second screw 10. The remaining sleeves 12 are slidably connected to the second guide rod 11. Corresponding curved plates 13 are installed on multiple sets of sleeves 12. Each set of curved plates 13 is slidably connected to a pressure-relieving plate 14. Multiple sets of springs 15 are connected between each set of pressure-relieving plates 14 and the corresponding curved plates 13. The pressure-relieving plates 14, together with the springs 15, clamp the metal casting and provide a buffering effect. The overall process is as follows: first, the first screw 5 is driven to rotate by the first motor 7 and, together with the first guide rod 6, the plates 4 on both sides slide within the groove 2 to the opening position of the mold 19. Then, by turning the handwheel 17, the corresponding sleeves 12, along with the opposing curved plates 13, undergo relative displacement. This allows the pressure relief plate 14 to remove the cast part from the mold 19. After the first motor 7 adjusts the position of the two sets of plates 4, the output end of the second motor 8 drives the two side frames 9 to rotate, aligning the clamped metal casting with the lower through slot 3. Then, the handwheel 17 is used to release the curved plate 13, and the metal casting will fall into the water tank 16 below. Since the molds 19 on both sides are integrally formed without gaps, the forming quality and use effect of the metal casting are improved. In addition, the pressure relief plate 14, together with the spring 15, clamps the metal casting and plays a buffering role, which can protect the surface of the metal casting from damage.

[0023] In this embodiment, a water tank 16 is provided under the operating table 1. The water tank 16 is placed directly below the through groove 3 to facilitate catching falling metal castings. A handwheel 17 is installed at one end of the second screw 10. Two sets of support plates 18 are installed on the operating table 1. A hydraulic cylinder 21 is installed on one set of support plates 18. A set of molds 19 is connected to the output end of the hydraulic cylinder 21. The other set of molds 19 is connected to the other set of support plates 18. Multiple sets of support rods 20 are installed under the operating table 1. A hand gripping groove is provided on the water tank 16 to facilitate removing the water tank 16 from under the operating table 1. The second screw 10 is a double-ended screw.

[0024] The working principle of this embodiment is as follows: During use, the hydraulic cylinder 21 drives the mold 19 on one side to press against the mold 19 on the other side. Then, molten metal is injected into the middle of the mold 19 through the injection port. After the injection is completed and the mold 19 is opened, the first motor 7 drives the first screw 5 to rotate and cooperates with the first guide rod 6 to make the plates 4 on both sides slide in the groove 2 to the opening position of the mold 19. Then, by turning the handwheel 17, the corresponding sleeve 12 and the opposite curved plate 13 are moved relative to each other, so that the pressure relief plate 14 pushes the cast part that has been poured out of the mold. The clamp in tool 19 is removed. After adjusting the position of the two sets of plates 4 by the first motor 7, the output end of the second motor 8 drives the two side frames 9 to rotate, and aligns the clamped metal casting with the lower through slot 3. Then, the curved plate 13 is released by the handwheel 17, and the metal casting will fall into the water tank 16 below. Since the molds 19 on both sides are integrally formed without gaps, the forming quality and use effect of the metal casting will be improved. In addition, the pressure relief plate 14 and the spring 15 clamp the metal casting to buffer it and protect the surface of the metal casting from damage.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
