Description

Technical Field

[0001] This utility model relates to the field of guiding structure technology, and in particular to a guiding structure device for feeding molds in an aluminum casting machine. Background Technology

[0002] As a key piece of equipment for realizing processes such as die casting and gravity casting of aluminum products, the precision and stability of the mold feeding process of the aluminum casting machine directly affects the casting qualification rate, mold wear rate and production efficiency. The guiding structure device of the mold feeding of the aluminum casting machine is the core component to ensure the precise alignment and smooth movement of the mold during the mold opening and closing process.

[0003] However, in existing technologies, due to inherent deficiencies in structural design, material compatibility, and buffering mechanisms, the guide pillars in traditional guide structures often adopt a single cylindrical cross-section. This type of design has weak bending resistance and is difficult to withstand the huge inertial impact force generated by the moving mold during high-speed mold closing. It is prone to deformation and vibration when subjected to force. At the same time, a certain fitting gap is reserved between the guide pillar and the guide sleeve to meet assembly requirements. During high-speed movement, this gap cannot form a stable support and instead amplifies the transmission of vibration energy, resulting in the inability to effectively attenuate the vibration. High-frequency vibration and resonance will cause the mold cavity, guide pillar, and other key components to continuously endure repeated friction and impact. The surface of the guide pillar is prone to wear, and the edge of the cavity may also crack due to continuous impact, which greatly shortens the overall service life of the mold and leads to a significant increase in the number of defective castings. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a guiding structure device for feeding molds in aluminum casting machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a mold feeding mechanism, a buffer mechanism is fixedly connected to the middle of the mold feeding mechanism, the mold feeding mechanism includes a fixed frame, a base is fixedly connected to the side of the fixed frame, a hydraulic cylinder is fixedly connected to the upper part of the base, a limit frame is fixedly connected to the end of the hydraulic cylinder, a second mold is fixedly connected to the bottom of the limit frame, a first mold is arranged below the second mold, the first mold is fixedly connected to the fixed frame, and a first limit rod is fixedly connected to the upper part of the first mold, and the second mold is slidably connected to the first limit rod; The upper end of the buffer mechanism is fixedly connected to the base, and the lower end of the buffer mechanism is fixedly connected to the second mold. The buffer mechanism includes a first mounting bracket, a ball joint connecting shaft, and a slide rail. A connecting rod assembly is movably connected to the surface of the first mounting bracket. A connector is fixedly connected to the end of the connecting rod assembly. The end of the ball joint connecting shaft is movably connected to the connector. Two sliders are slidably connected inside the slide rail. The sliders are fixedly connected to the ball joint connecting shaft, and a first spring is fixedly connected between the two sliders.

[0006] Preferably, a second limiting rod is fixedly connected to the surface of the base, and the limiting frame is slidably connected to the second limiting rod.

[0007] Preferably, two linkage assemblies are mounted on the surface of the first mounting bracket, and the two linkage assemblies are symmetrically distributed on the surface of the first mounting bracket.

[0008] Preferably, a damping component is installed inside the connecting rod assembly, one end of which is movably connected to the connecting rod assembly, and the other end of which is movably connected to the surface of the first mounting bracket.

[0009] Preferably, a third limiting rod is fixedly connected inside the slide rail, and the slider is slidably connected to the third limiting rod.

[0010] Preferably, a second spring is fixedly connected to both ends of the slide rail, and the end of the second spring is fixedly connected to the side of the slider.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the buffer mechanism can fully absorb impact energy. When the No. 2 mold moves downward, the connecting rod assembly will rotate along the No. 1 mounting frame. The connector at its end drives the ball joint connecting shaft and the slider to slide along the slide rail. During this process, the No. 1 spring is compressed and the No. 2 spring is stretched. The two absorb the vertical impact force generated when the No. 2 mold collides with the No. 1 mold through elastic deformation. Combined with the buffering effect of the damping assembly on the horizontal impact force, it can significantly reduce the high-frequency vibration and resonance phenomenon during high-speed mold closing. The overall structure not only ensures the accuracy of mold feeding guidance, but also reduces the repeated friction and impact of vibration on key components such as the No. 1 mold and the No. 2 mold, effectively extending the service life of the mold. At the same time, it avoids casting defects caused by vibration, improves casting quality, and further enhances the overall stability of the aluminum casting machine during high-speed operation, reducing the need for unplanned downtime maintenance. 2. In this utility model, the fixed frame in the mold mechanism provides a stable installation foundation for the overall structure. When the hydraulic cylinder pushes the limit frame to move the No. 2 mold downward, the No. 1 limit rod can accurately limit the movement trajectory of the No. 2 mold. At the same time, the limit frame slides along the No. 2 limit rod, and the No. 2 limit rod further constrains the movement of the limit frame. This double limit design effectively avoids the No. 2 mold from deviating during high-speed movement, greatly improves its stability during movement, and reduces vibration caused by movement deviation from the source. 3. In this utility model, the No. 3 limiting rod fixed inside the slide rail is slidably connected to the slider, which can limit the sliding direction of the slider within the slide rail, preventing the slider from deviating and causing uneven force on the No. 1 and No. 2 springs, ensuring that the elastic element always stably performs its buffering function. The overall structure not only enhances the stability and accuracy of the mold feeding guide, but also improves the comprehensiveness and reliability of impact buffering, effectively reducing the wear of the No. 1 and No. 2 molds caused by vibration and impact, extending their service life, and at the same time avoiding defects in the castings due to vibration, further improving the quality and efficiency of aluminum casting production.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1: As Figure 1 - Figure 5As shown, this utility model provides a guiding structure device for feeding molds in an aluminum casting machine, including a mold feeding mechanism 1. A buffer mechanism 2 is fixedly connected to the middle of the mold feeding mechanism 1. The mold feeding mechanism 1 includes a fixed frame 11. A base 12 is fixedly connected to the side of the fixed frame 11. A hydraulic cylinder 13 is fixedly connected to the upper part of the base 12. A limit frame 17 is fixedly connected to the end of the hydraulic cylinder 13. A second mold 16 is fixedly connected to the bottom of the limit frame 17. A first mold 14 is arranged below the second mold 16. The first mold 14 is fixedly connected to the fixed frame 11, and a first limit rod 15 is fixedly connected to the upper part of the first mold 14. The second mold 16 is slidably connected to the first limit rod 15. The upper end of the buffer mechanism 2 is fixedly connected to the base 12, and the lower end of the buffer mechanism 2 is fixedly connected to the second mold 16. The buffer mechanism 2 includes a first mounting bracket 21, a ball joint connecting shaft 25, and a slide rail 26. A connecting rod assembly 22 is movably connected to the surface of the first mounting bracket 21. A connector 24 is fixedly connected to the end of the connecting rod assembly 22. The end of the ball joint connecting shaft 25 is movably connected to the connector 24. Two sliders 27 are slidably connected inside the slide rail 26. The sliders 27 are fixedly connected to the ball joint connecting shaft 25. A first spring 29 is fixedly connected between the two sliders 27. A second spring 210 is fixedly connected to both ends of the slide rail 26. The end of the second spring 210 is fixedly connected to the side of the slider 27.

[0017] The specific settings and functions of this embodiment are described below: During the aluminum casting process, the hydraulic cylinder 13 pushes the limiting frame 17 to move downward. At this time, the limiting frame 17 pushes the second mold 16 to move downward. During the downward movement of the second mold 16, the first limiting rod 15 limits it, thereby improving the stability of the second mold 16 when it moves. At the same time, the limiting frame 17 slides along the second limiting rod 18 to limit the movement of the limiting frame 17, thereby improving the stability of the first limiting rod 15 when it moves. When mold 16 moves downward, one end of the connecting rod assembly 22 rotates along the mounting bracket 21, and the other end drives the connector 24 to move horizontally, thereby driving the ball joint connecting shaft 25 and the slider 27 to slide along the slide rail 26. At the same time, spring 29 is compressed and spring 210 is stretched. When mold 16 impacts the surface of mold 14 downward, spring 29 and spring 210 buffer the vertical impact force generated by the impact, while damping assembly 23 buffers the horizontal impact force generated by the impact. In the mold feeding mechanism 1, the fixed frame 11 provides a stable mounting foundation for the overall structure. When the hydraulic cylinder 13 pushes the limiting frame 17 to move the second mold 16 downward, the first limiting rod 15 can precisely limit the movement trajectory of the second mold 16. At the same time, the limiting frame 17 slides along the second limiting rod 18, and the second limiting rod 18 further constrains the movement of the limiting frame 17. This double limiting design effectively avoids the second mold 16 from deviating during high-speed movement, greatly improving its stability during movement and reducing vibration caused by movement deviation from the source. Meanwhile, the buffer mechanism 2 can fully absorb impact energy. When the second mold 16 moves downward, the connecting rod assembly 22 will rotate along the first mounting frame 21, and its end connector 24 carries... The moving ball joint connecting shaft 25 and the slider 27 slide along the slide rail 26. During this process, the first spring 29 is compressed and the second spring 210 is stretched. The two absorb the vertical impact force generated when the second mold 16 and the first mold 14 collide through elastic deformation. Combined with the buffering effect of the damping component 23 on the horizontal impact force, it can significantly reduce the high-frequency vibration and resonance phenomenon during high-speed mold closing. The overall structure not only ensures the accuracy of mold feeding guidance, but also reduces the repeated friction and impact of vibration on key components such as the first mold 14 and the second mold 16, effectively extending the service life of the mold. At the same time, it avoids casting defects caused by vibration, improves casting quality, and further enhances the overall stability of the aluminum casting machine during high-speed operation, reducing the need for unplanned downtime maintenance.

[0018] Example 2: Figure 2 - Figure 5 As shown, a second limiting rod 18 is fixedly connected to the surface of the base 12, and the limiting frame 17 is slidably connected to the second limiting rod 18. Two connecting rod assemblies 22 are installed on the surface of the first mounting frame 21. The two connecting rod assemblies 22 are symmetrically distributed on the surface of the first mounting frame 21. A damping assembly 23 is installed inside the connecting rod assembly 22. One end of the damping assembly 23 is movably connected to the connecting rod assembly 22, and the other end of the damping assembly 23 is movably connected to the surface of the first mounting frame 21. A third limiting rod 28 is fixedly connected inside the slide rail 26, and the slider 27 is slidably connected to the third limiting rod 28.

[0019] The overall effect of this embodiment is that the second limiting rod 18, fixed to the surface of the base 12, forms a sliding connection with the limiting frame 17. When the hydraulic cylinder 13 pushes the limiting frame 17 to move the second mold 16, it can form a double limiting structure together with the first limiting rod 15, further constraining the movement trajectory of the limiting frame 17, preventing lateral deviation during high-speed movement, and greatly improving the guiding accuracy of the mold feeding process; the two connecting rod assemblies 22 symmetrically distributed on the surface of the first mounting frame 21 can make the force on the second mold 16 more uniform when it moves downward, avoiding the imbalance of the buffer mechanism 2 caused by uneven force on one side, and providing a stable foundation for subsequent impact absorption; the connecting rod assembly 2 The damping component 23 on the inner side, connected to the connecting rod assembly 22 and the first mounting bracket 21 at both ends, can efficiently absorb horizontal vibration energy when the connecting rod assembly 22 rotates. Combined with the vertical buffering of the first spring 29 and the second spring 210, it forms a comprehensive "horizontal + vertical" impact buffering system, significantly reducing resonance and high-frequency vibration during high-speed mold closing. The third limiting rod 28, fixed inside the slide rail 26, is slidably connected to the slider 27, limiting the sliding direction of the slider 27 within the slide rail 26. This prevents the slider 27 from shifting, which could lead to uneven force on the first spring 29 and the second spring 210, ensuring that the elastic elements always stably perform their buffering function. The overall structure not only enhances the stability and precision of the mold feeding guide but also improves the comprehensiveness and reliability of the impact buffering, effectively reducing wear on the first mold 14 and the second mold 16 caused by vibration and impact, extending their service life, and preventing defects in the castings due to vibration, further improving the quality and efficiency of aluminum casting production.

[0020] The usage and working principle of this device are as follows: During the aluminum casting process, the hydraulic cylinder 13 pushes the limiting frame 17 to move downward. At this time, the limiting frame 17 pushes the second mold 16 to move downward. During the downward movement of the second mold 16, the first limiting rod 15 limits it, thereby improving the stability of the second mold 16 during movement. At the same time, the limiting frame 17 slides along the second limiting rod 18 to limit the movement of the limiting frame 17. When mold 16 moves downward, one end of the connecting rod assembly 22 rotates along the mounting bracket 21, and the other end drives the connector 24 to move horizontally, thereby driving the ball joint connecting shaft 25 and the slider 27 to slide along the slide rail 26. At the same time, spring 29 is compressed and spring 210 is stretched. When mold 16 impacts the surface of mold 14 downward, springs 29 and 210 buffer the vertical impact force generated by the impact, while damping assembly 23 buffers the horizontal impact force generated by the impact.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
