Description

An automatic centering device for the injection rod of a die-casting machine Technical Field

[0001] This utility model relates to the field of die casting machine technology, specifically to an automatic centering device for the injection rod of a die casting machine. Background Technology

[0002] Die casting machines inject liquid or semi-liquid metal materials into a pre-designed mold cavity under high pressure. Under pressure, the molten metal quickly solidifies and forms a shape within the mold, thereby obtaining high-precision, high-quality metal parts.

[0003] In the current die-casting production process, the precise alignment of the injection tube and injection rod is a crucial step in ensuring the quality of die-cast parts and the normal operation of the equipment. Common die-casting machine injection rod alignment devices on the market often suffer from problems such as dispersed structure and unreasonable layout. Each component occupies a large space, which not only increases the difficulty of equipment installation and debugging, but also makes subsequent maintenance inconvenient and difficult to adapt to different models of die-casting machines. Traditional alignment operations usually require the use of a variety of complex tools and a cumbersome process to clamp and align the injection tube and injection rod. This not only requires high professional skills from the operators, but also takes a long time, resulting in low equipment debugging efficiency, which greatly affects the production schedule and increases labor costs. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic centering device for the injection rod of a die-casting machine, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic centering device for an injection rod in a die-casting machine, comprising an injection tube and an injection rod, wherein a clamping plate is attached to the outer wall of the injection tube, a driving component is rotatably mounted on one side wall of the clamping plate, a clamping component is rotatably mounted inside the driving component, four translation components slide around the periphery of the clamping plate, a driving gear ring is rotatably mounted on one side of the translation component, four driving clamping rings are rotatably mounted around the outer wall of the translation component, and one side of the driving clamping rings meshes with one side of the driving gear rings, a lifting screw is threaded inside the driving clamping rings, and a clamping arc block is rotatably mounted at the bottom end of the lifting screw.

[0006] Preferably, one side of the drive gear ring is provided with teeth that match the outer wall of the drive clamp ring, thereby enabling it to rotate.

[0007] Preferably, the drive clamp rotating ring has a through hole inside, and the through hole is provided with a thread that matches the lifting screw, so that it can be moved by the drive gear ring.

[0008] Preferably, the driving component includes a limiting rotating block, and the limiting rotating block is rotatably mounted on one side wall of the clamping plate. The limiting rotating block has a through hole inside, and a driving screw is threaded inside the through hole. A linkage rotating block is rotatably mounted on one end of the driving screw, and a driving rotating ring is rotatably mounted on one side wall of the linkage rotating block. The driving rotating ring rotates on one side of the clamping plate.

[0009] Preferably, the clamping member includes a linkage slide frame, the drive rotating ring has a rotating linkage slide frame inside, the linkage slide frame has a sliding rotating clamping rod inside, a limiting vertical rod is fixed to one side wall of the support clamping plate, and the limiting vertical rod has a rotating clamping rod on its outer wall.

[0010] Preferably, the translation component includes a sliding crossbar, the sliding crossbar is slidably disposed inside the periphery of the support clamping plate, a driving nut is rotatably disposed on one side of the support clamping plate, and the internal thread of the driving nut has a sliding crossbar, and a driven ring is fixed at one end of the sliding crossbar.

[0011] Preferably, the outer wall of the sliding crossbar is provided with a thread that matches the inner wall of the driving nut, thereby enabling the sliding crossbar to move.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The drive unit, clamping unit, and translation unit are organically integrated by the support and clamping plate. The layout of each component is reasonable and makes effective use of space. While realizing the automatic alignment of the injection tube and injection rod, the overall size of the device is reduced, which facilitates installation and maintenance. It is suitable for a variety of die casting machines.

[0014] By rotating a few components such as the drive screw, drive nut, and drive gear ring, the clamping and centering of the injection tube and injection rod can be achieved sequentially. This eliminates the need for complicated operating procedures and specialized tools, reducing the workload of operators, improving centering and adjustment efficiency, and shortening equipment debugging time.

[0015] By using components such as limit blocks and limit rods to precisely limit the movement of each moving part, and in conjunction with the high-precision characteristics of threaded transmission and gear meshing, the positioning of the injection tube and injection rod is ensured to be accurate during the alignment process. This effectively reduces problems such as injection rod wear and unstable quality of die castings caused by alignment deviations, thereby improving the quality and reliability of die casting production.

[0022] 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.

[0023] Please refer to Figures 1-5. This utility model provides a technical solution: an automatic centering device for the injection rod of a die-casting machine, including an injection tube 1 and an injection rod 2. A clamping plate 3 is attached to the outer wall of the injection tube 1. The clamping plate 3 can support parts such as the sliding crossbar 11 and the driving nut 12. A driving component rotates on one side wall of the clamping plate 3. A clamping component rotates inside the driving component. Four translation components slide around the periphery of the clamping plate 3. A driving gear ring 14 rotates on one side of the translation component. When the driven ring 13 drives the driving gear ring 14 to move, the driving gear ring 14 will mesh with the driving clamping ring 15 through its teeth, thereby driving the driving clamping ring 15 to rotate. Four driving clamping rings 15 rotate around the periphery of the outer wall of the translation component, and one side of the driving clamping ring 15 meshes with one side of the driving gear ring 14. The driving clamping ring 15 is driven by the driving gear ring 14. During rotation, due to the threaded engagement, the lifting screw 16 moves linearly within the drive clamping ring 15. The drive clamping ring 15 has an internal thread with the lifting screw 16. As the lifting screw 16 moves linearly under the drive clamping ring 15, it pushes or pulls the clamping arc block 17 up and down. The bottom end of the lifting screw 16 has a rotating clamping arc block 17. When the lifting screw 16 moves the clamping arc block 17 closer to the injection rod 2, the clamping arc block 17 clamps the injection rod 2. Through the coordinated action of the four clamping arc blocks 17, the injection rod 2 is automatically aligned within the injection tube 1. One side of the drive gear ring 14 has teeth that match the outer wall of the drive clamping ring 15, enabling its rotation. The drive clamping ring 15 has an internal through-hole with threads matching the lifting screw 16, which is driven by the drive gear ring 14 to move.

[0024] The driving component includes a limiting rotating block 4. The limiting rotating block 4 rotates on one side wall of the clamping plate 3, supporting the driving screw 5. Simultaneously, its internal threads drive the driving screw 5 to move. The limiting rotating block 4 has a through hole with the driving screw 5 threaded inside. When the driving screw 5 moves linearly under the drive of the limiting rotating block 4, it pushes or pulls the linkage rotating block 6 to move together. One end of the driving screw 5 has the linkage rotating block 6 rotating on it. As the linkage rotating block 6 moves with the driving screw 5, it drives the driving ring 7, which is rotatably connected to it, to rotate on one side of the clamping plate 3. The driving ring 7 rotates on one side wall of the linkage rotating block 6, and its rotation on one side of the clamping plate 3 causes the connected clamping component to move, thereby achieving initial clamping of the injection rod 2.

[0025] The clamping component includes a linkage slide frame 8. The drive ring 7 rotates internally with the linkage slide frame 8. When the drive ring 7 rotates, it drives the linkage slide frame 8 to rotate as well. The rotation of the linkage slide frame 8 provides power and direction for the movement of the rotating clamping rod 9. The rotating clamping rod 9 slides internally within the linkage slide frame 8. When the linkage slide frame 8 rotates, it pushes the rotating clamping rod 9 to slide within the linkage slide frame 8 and rotate around the limiting vertical rod 10. The rotation of the rotating clamping rod 9 brings it closer to the injection tube 1. The limiting vertical rod 10 is fixed to one side wall of the clamping plate 3, and the rotating clamping rod 9 rotates on the outer wall of the limiting vertical rod 10. The limiting vertical rod 10 is fixed to one side wall of the clamping plate 3, providing a support point for the rotation of the rotating clamping rod 9.

[0026] The translation component includes a sliding crossbar 11. The sliding crossbar 11 slides inside the periphery of the clamping plate 3. When the drive nut 12 rotates, the sliding crossbar 11 will make linear motion within the clamping plate 3 due to the threaded engagement. The drive nut 12 rotates on one side of the clamping plate 3, and the internal thread of the drive nut 12 has the sliding crossbar 11. Rotating the drive nut 12 can control the linear motion of the sliding crossbar 11. One end of the sliding crossbar 11 is fixed with a driven ring 13. The movement of the driven ring 13 will drive the connected drive toothed ring 14 to move together, thereby adjusting the position of the clamping arc block 17 in the horizontal direction. The outer wall of the sliding crossbar 11 is provided with a thread that matches the inner wall of the drive nut 12, thereby enabling the sliding crossbar 11 to move.

[0027] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0028] Move the clamping plate 3 to the outer wall of the injection tube 1, then rotate the drive screw 5. The rotation of the drive screw 5, through the limiting block 4, causes the linkage block 6 to move. The linkage block 6 causes the drive ring 7 to rotate. When the drive ring 7 rotates, the linkage slide frame 8 inside it also rotates. The linkage slide frame 8 causes the rotating clamping rod 9 to rotate. One end of the rotating clamping rod 9 is limited by the limiting vertical rod 10, causing the other end to move inward. The rotating clamping rod 9 moves inward to clamp the injection tube 1. Then rotate the drive nut 12. The drive nut 12 rotates through the thread set on the inner wall. The sliding crossbar 11 moves forward, which in turn moves the driven ring 13 forward. The driven ring 13 moves forward to the outer wall of the injection rod 2, and rotates the drive gear ring 14. The drive gear ring 14 rotates and drives the clamping ring 15 to rotate through the teeth on one side. The clamping ring 15 rotates and drives the lifting screw 16 to move downward through the threads on the inner wall. The lifting screw 16 drives the clamping block 17 to move upward to clamp the injection rod 2. Thus, the injection tube 1 and the injection rod 2 are aligned through the lifting screw 16, the driven ring 13, the sliding crossbar 11, and the support clamping plate 3.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
