Description

Technical Field

[0001] This utility model belongs to the field of casting machine technology, specifically relating to a casting machine mold support assembly. Background Technology

Some casting machines can adjust the die position forward and backward, but adjusting only forward and backward has limited effect. Adjusting the height, tilt angle, etc., requires a more complex process, such as disassembling screws for local adjustments, resulting in low adjustment efficiency and high operator skill.

[0021] This utility model provides a casting machine mold support assembly, which solves the problems of inconvenient mold adjustment and low efficiency in existing casting machines.

[0022] Please see Figures 1 to 5 This utility model discloses a casting machine mold support assembly. A set of support assemblies is connected to each side of the mold 1. The two sets of support assemblies are symmetrically structured, thus supporting and adjusting both sides (or the two ends in the length direction) of the mold 1 respectively. A mold head 27 is located below the middle of the mold 1, and a roller 25 of the casting machine is located below the mold head. A steel belt 26 is driven onto the roller 25. Figure 1 The diagram below is a simplified illustration. To make the other structures clear, only a partial cross-sectional outline of the roller and steel strip is shown. The slurry will flow from the die head 27 onto the steel strip 26.

[0023] Each support assembly includes a base plate 2, a side plate 3, and a lifting plate 4. The base plate 2 and / or the side plate 3 are fixedly connected to the frame of the casting machine (in other words, the base plate 2 and the side plate 3 are fixed and do not move during operation). The lifting plate 4 is slidably connected to the side plate 3 via a vertical lifting guide rail assembly 5. The mold 1 is slidably connected to the lifting plate 4 via a horizontal transverse guide rail assembly 7, and also includes a transverse adjustment mechanism. Thus, driven by the transverse adjustment mechanism and limited and guided by the transverse guide rail assembly 7, the mold 1 can be transversely moved (moved back and forth relative to the steel strip conveying direction). This allows control over the position of the slurry released by the mold head 27 corresponding to the circumference of the roller 25, meeting different process effect requirements. By adjusting the back and forth positions of both ends of the mold 1, the parallelism of the mold head 27 and the roller 25 along their length can be controlled.

[0024] A telescopic cylinder 6 is installed on the base plate 2, and the other end of the telescopic cylinder 6 is connected to the lifting plate 4. The telescopic cylinder 6 is, for example, a hydraulic cylinder or a pneumatic cylinder. In this way, the telescopic cylinder 6 is used to drive and the lifting guide rail assembly 5 is used to limit and guide, so as to realize the stable lifting and lowering of the electric control lifting plate 4. It also includes a lifting fine adjustment mechanism, which can further fine adjust the position of the lifting plate 4. In particular, when the mold 1 is located in a low position close to the roller 25, this low position is first coarsely controlled by the telescopic cylinder 6, and then finely adjusted by the lifting fine adjustment mechanism to accurately adjust the distance between the mold head 27 and the steel strip 26 to the required distance.

[0025] like Figure 2 , Figure 3 In the preferred embodiment shown, the lifting and fine-tuning mechanism includes a lifting and fine-tuning top column 8 and a top column lifting mechanism 9 connected together. The lifting plate 4 is located above the base plate 2, and a fine-tuning part 10 is provided on the lifting plate 4. The upper end of the telescopic cylinder 6 (such as the end of the piston rod) is vertically slidably connected to the fine-tuning part 10, and the upper part of the fine-tuning part 10 has a limiting part 11 that can block the upper end of the telescopic cylinder 6. Further, the fine-tuning part 10 is located below the lifting plate 4, and the fine-tuning part 10 has a hollow cylindrical cavity inside. The limiting part 11 is a baffle at the upper end of the cylindrical cavity, and the upper end of the telescopic cylinder 6 is slidably connected to the cylindrical cavity of the fine-tuning part 10.

[0026] The working principle of the lifting and fine-tuning mechanism in this scheme is as follows. The diagram shows adjustments to the extension and retraction of the lifting and fine-tuning top column 8 / telescopic cylinder 6 for clarity. In the actual structure, when the lifting and fine-tuning top column 8 is not in contact with the lifting plate 4, the upper end of the telescopic cylinder 6 will always be in contact with the limiting part 11, thus supporting the lifting plate 4. The lifting and fine-tuning top column 8 is lifted and lowered independently of the telescopic cylinder 6. After being raised, it can further lift the lifting plate 4, thus fine-tuning and increasing the distance between the die head and the steel strip. During this process, the fine-tuning part 10 rises with the lifting plate 4, and slides upward relative to the upper end of the telescopic cylinder 6, causing the upper end of the telescopic cylinder 6 to disengage from the limiting part 11. Optionally, with the lifting plate 4 supported by the lifting and fine-tuning top column 8, the telescopic cylinder 6 can be further retracted, and then the lifting and fine-tuning top column 8 can be adjusted to descend, thereby achieving a fine-tuning reduction of the distance between the die head and the steel strip.

[0027] Furthermore, the top column lifting mechanism 9 is connected to a rotating rod 12. The top column lifting mechanism 9 is a mechanical transmission structure, and the rotating rod 12 is connected to the lifting and fine-tuning top column 8 through the top column lifting mechanism 9. Based on existing technology, mechanical transmission structures that can realize fine-tuning functions are easy to implement and exist in various ways. For example, the rotating rod 12 drives a threaded sleeve to rotate horizontally through gear transmission. The outer side of the threaded sleeve is rotatably connected to the fixed seat in the top column lifting mechanism 9, and the inner side of the threaded sleeve is threadedly connected to the lifting and fine-tuning top column 8. The lifting and fine-tuning top column 8 is restricted by a limiting structure to only perform lifting and lowering movements. In this way, high-precision lifting and lowering control of the lifting and fine-tuning top column 8 is achieved by using the thread and limiting mechanism. It is conceivable that other methods such as lead screws and racks can also be used similarly, which will not be elaborated here.

[0028] The end of the rotating rod 12 is connected to a fine-tuning handwheel 13, or the rotating rod 12 is driven to connect to the fine-tuning handwheel 13. In the illustrated embodiment, the rotating rod 12 is connected to the fine-tuning handwheel 13 via a sprocket and chain drive for easier adjustment and control.

[0029] It should be noted that the above are only preferred embodiments of the present utility model, and the present utility model is not limited thereto. Based on the prior art, there are many other ways to achieve lifting and fine adjustment, such as the position of the telescopic cylinder 6 can be lifted and finely adjusted, or a lifting and finely adjustable structure is provided between the upper end of the telescopic cylinder 6 and the lifting plate 4, etc.

[0030] Please see Figure 2 , Figure 4 In this embodiment, the transverse adjustment mechanism includes a transverse screw 14, a screw connecting seat 15 is provided on the lifting plate 4, the middle part of the transverse screw 14 is threadedly connected to the screw connecting seat 15, one end of the transverse screw 14 is rotatably connected to the mold 1 (directly or indirectly), and the other end of the transverse screw 14 is provided with a transverse handwheel 16. Thus, by rotating the handwheel, the mold 1 is pushed to move along the transverse guide rail assembly 7.

[0031] Preferably, such as Figure 1 , 2 As shown in Figures 4 and 5, it also includes a die head angle adjustment mechanism for adjusting the angle of the die head, for example... Figure 5 The image shows the mold head facing downwards, which can be rotated and adjusted to tilt as needed. The mold head angle adjustment mechanism includes a mold rotating seat 17, on which a mold mounting shaft 18 is rotatably connected. The end of the mold 1 is connected to the mold mounting shaft 18. Correspondingly, the mold rotating seat 17 is slidably connected to the lifting plate 4 via a transverse sliding guide rail assembly 7, and the transverse adjustment mechanism is connected to the mold rotating seat 17. In other words, the mold 1 has a rotating seat at its end, and the mold 1 is connected to the lifting plate 4, etc., via this rotating seat.

[0032] More specifically, a rotating arm 19 is connected to the mold mounting shaft 18. An angle adjusting rod 20 is rotatably connected to the end of the rotating arm 19. The angle adjusting rod 20 has external threads and is threaded with a first nut 21 and a second nut 22. An adjusting rod positioning seat 23 is provided on the screw connecting seat 15. The angle adjusting rod 20 passes through the adjusting rod positioning seat 23, and the first nut 21 and the second nut 22 are clamped on both sides of the adjusting rod positioning seat 23. A rotatable rotating block 24 is provided in the adjusting rod positioning seat 23. The rotating block 24 has a through hole, through which the angle adjusting rod 20 passes. The first nut 21 and the second nut 22 are clamped on both sides of the rotating block 24. The rotation axis direction of the rotating block 24 and the rotation axis direction of the rotating arm 19 are both parallel to the length direction of the mold mounting shaft 18. Figure 5 As shown, by adjusting the positions of the first nut 21 and the second nut 22 on the angle adjustment rod 20, the angle adjustment rod 20 can be moved left or right, thereby driving the rotating arm 19 to rotate, which in turn drives the mold mounting shaft 18 and the mold 1 to rotate. Preferably, the mold head angle adjustment mechanism also has an angle scale and a pointer for fine-tuning.

[0033] It should be noted that the above are only preferred embodiments of the present invention, and the present invention is not limited thereto. Based on the prior art, there are many other ways to achieve similar angle adjustment effects.

[0034] In summary, the casting machine mold support assembly of this utility model allows for forward and backward lateral movement and lifting adjustment on both sides of the mold. The lateral movement adjustment controls the relative position of the mold to the casting machine roller below it. The telescopic cylinder allows for switching between working and maintenance states and coarse adjustments. Specifically, the working state is when the mold is close to the casting machine roller, while the maintenance state is when the mold is raised by the telescopic cylinder, facilitating mold maintenance and replacement. Furthermore, it has a lifting fine-tuning mechanism, which allows for fine-tuning with higher precision based on the initial working position reached after the telescopic cylinder retracts. Therefore, it is convenient to adjust, efficient, and precise, which helps to improve the quality and efficiency of film production.
