Description

Technical Field

[0001] This utility model relates to the field of mold frame processing, and specifically to a feeding mechanism for mold frame processing. Background Technology

[0002] Mold frame machining is a common processing method in modern manufacturing. A mold frame is a device used to support workpieces and cutting tools. It can keep the workpiece in a stable position during processing, while allowing the cutting tool to cut accurately according to design requirements. As the skeleton structure of injection molds, the machining accuracy of the mold frame directly affects the service life of the mold. The feeding mechanism plays a crucial role in mold frame machining. It is responsible for transporting raw materials or semi-finished products from the storage area to the processing area and ensuring their accurate position and stable speed to meet the needs of subsequent processing steps. Through precise feeding control, production efficiency and product quality can be improved, and production costs can be reduced.

[0003] The existing feeding mechanism for mold frame processing lacks the ability to center and correct the mold frame workpiece during transport, causing it to remain in a misaligned position. This misalignment leads to increased processing errors, affecting the accuracy and quality of the final product. Furthermore, the swaying and misalignment of the workpiece during transport also causes instability in the processing, increasing scrap rate and production costs. In the long run, manual adjustment of the workpiece position is required, further reducing production efficiency.

[0004] Therefore, it is necessary to invent a feeding mechanism for mold frame processing to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding mechanism for mold frame processing. Through a centering frame, auxiliary slide rail, auxiliary sliding sleeve, first telescopic cylinder, push rack, centering gear, first centering plate, and second centering plate, the centering mechanism aims to center the mold frame workpiece, which has shifted position after passing through the centering frame, by moving the centers of the first and second centering plates together. This helps ensure the positional accuracy of the mold frame workpiece in subsequent processing, thereby improving processing precision. Furthermore, the centering design reduces the shaking and shifting of the mold frame workpiece during processing, enhancing processing stability and reducing processing errors and scrap rates caused by workpiece instability. The automated design reduces the workload of operators, allowing them to focus on other more important tasks. This addresses the problem in existing mold frame processing feeding mechanisms where the lack of centering and alignment during transport causes the mold frame workpieces to remain misaligned during transport. This misalignment leads to increased processing errors, affecting the accuracy and quality of the final product. Furthermore, the swaying and misalignment of the workpieces during transport cause instability in the processing, increasing scrap rates and production costs. Long-term use also necessitates manual adjustment of the workpiece position, further reducing production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for mold frame processing, including a feeding frame and a main body for feeding materials during mold frame processing;

[0007] A telescopic support frame is set at the bottom of the feeding frame to adjust the height of the feeding frame. A first infrared grating is fixedly installed on the top of the feeding frame. An electric conveyor belt is set on the top of the feeding frame. A fixing bolt passes through the outside of the feeding frame. A centering frame is threaded to the front end of the fixing bolt.

[0008] An auxiliary slide rail is installed inside the centering frame for sliding connection of an auxiliary slide sleeve. A push block is fixedly installed on one side of the auxiliary slide sleeve. A first telescopic cylinder is fixedly installed inside the centering frame. The front end of the first telescopic cylinder is fixedly connected to the push block. A push rack is fixedly installed on the other side of the auxiliary slide sleeve. A centering gear is movably connected to the outside of the push rack. A first centering plate is fixedly installed on the outside of the auxiliary slide sleeve. A second centering plate is movably connected to the other side of the centering gear.

[0009] Preferably, the centering frame is threadedly connected to the feeding frame, and the first infrared grating is symmetrically arranged about the central axis of the feeding frame.

[0010] Preferably, the first centering plate is slidably connected to the centering frame, and the pushing rack is meshed with the centering gear.

[0011] Preferably, a drive controller is fixedly installed on the outside of the feeding rack, and a second infrared grating is fixedly installed on the top of the feeding rack.

[0012] Preferably, a limiting frame is fixedly installed on the right side of the second infrared grating, a second telescopic cylinder is fixedly installed on the outside of the limiting frame, a limiting plate is fixedly installed at the front end of the second telescopic cylinder, and a discharge frame is fixedly installed on the right side of the feeding frame.

[0013] Preferably, the limiting plate is movably connected to the limiting frame, and the limiting plate is symmetrically arranged about the central axis of the feeding frame.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model is equipped with a centering frame, auxiliary slide rail, auxiliary sliding sleeve, first telescopic cylinder, push rack, centering gear, first centering plate and second centering plate. When the mold frame workpiece conveyed by the electric conveyor belt passes through the centering frame, the extension and retraction of the first telescopic cylinder pushes the push block, thereby causing the first centering plate to slide on the centering frame. In this way, the first centering plate slides closer to the center of the centering frame. Then, the push rack, which is meshed with the centering gear, also drives the second centering plate to slide in the opposite direction on the other side, moving closer to the centering frame. In this way, the centering movement of the first centering plate and the second centering plate will straighten and center the mold frame workpiece that has passed through the centering frame and whose position has been offset. This helps to ensure the positional accuracy of the mold frame workpiece in the subsequent processing, thereby improving the processing accuracy. Moreover, the straightening and centering design can reduce the shaking and offset of the mold frame workpiece during processing, enhance the processing stability, and reduce the processing error and scrap rate caused by the unstable position of the workpiece. At the same time, the automated design reduces the labor intensity of the operator, allowing him to focus on other more important work tasks.

[0016] 2. This utility model is equipped with a first infrared grating, a drive controller, a second infrared grating, a limit frame, and a second telescopic cylinder. When using the feeding mechanism of the mold frame processing, since both the first and second infrared gratings are connected to the drive controller, the position and width of the mold frame workpiece are detected after it passes through the first and second infrared gratings. After passing the centered mold frame workpiece, the drive controller controls the second telescopic cylinder to extend and retract, so that the two sets of limit plates on the limit frame are adjusted to a suitable distance and fit against the outside of the mold frame workpiece, limiting the current conveying trajectory of the mold frame workpiece and keeping it in a centered position for conveying. This can accurately control the workpiece position, reduce processing errors caused by position deviation, and realize automatic detection of workpiece position and width as well as automatic adjustment of the limit frame distance without manual intervention, thus improving processing efficiency.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-6 The feeding mechanism shown includes a feeding frame 1 and a main body for feeding materials during mold frame processing;

[0028] Telescopic support frame 2 is set at the bottom of feeding frame 1 to adjust the height of feeding frame 1. A first infrared grating 3 is fixedly installed on the top of feeding frame 1. An electric conveyor belt 4 is set on the top of feeding frame 1. A fixing bolt 5 passes through the outside of feeding frame 1. A centering frame 6 is threaded to the front end of the fixing bolt 5.

[0029] An auxiliary slide rail 7 is located inside the centering frame 6 and is used to slide and connect the auxiliary slide sleeve 8. A push block 9 is fixedly installed on one side of the auxiliary slide sleeve 8. A first telescopic cylinder 10 is fixedly installed inside the centering frame 6, and the front end of the first telescopic cylinder 10 is fixedly connected to the push block 9. A push rack 11 is fixedly installed on the other side of the auxiliary slide sleeve 8, and a centering gear 12 is movably connected to the outside of the push rack 11. A first centering plate 13 is fixedly installed on the outside of the auxiliary slide sleeve 8, and a second centering plate 13 is movably connected to the other side of the centering gear 12. The extension and retraction of the centering plate 14 and the first telescopic cylinder 10 push the push block 9, thereby causing the first centering plate 13 to slide on the centering frame 6. In this way, the first centering plate 13 slides towards the center of the centering frame 6. Then, the push rack 11, which is meshed with the centering gear 12, also drives the second centering plate 14 to slide in the opposite direction and move towards the centering frame 6. In this way, the center movement of the first centering plate 13 and the second centering plate 14 will straighten and center the mold frame workpiece that has passed through the centering frame 6 and whose position has been offset.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the centering frame 6 is threadedly connected to the feeding frame 1. The first infrared grating 3 is symmetrically arranged around the central axis of the feeding frame 1. The first infrared grating 3 is located in front of the centering frame 6 and is used to detect the size and width of the mold frame workpiece passing through. The first centering plate 13 is slidably connected to the centering frame 6. The push rack 11 is meshed with the centering gear 12. The extension and retraction of the first telescopic cylinder 10 pushes the push block 9, thereby causing the first centering plate 13 to slide on the centering frame 6. In this way, the first centering plate 13 slides towards the center of the centering frame 6.

[0031] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, a drive controller 15 is fixedly installed on the outside of the feeding rack 1. A second infrared grating 16 is fixedly installed above the feeding rack 1. Since both the first infrared grating 3 and the second infrared grating 16 are connected to the drive controller 15, the position and width of the workpiece will be detected after it passes through the first infrared grating 3 and the second infrared grating 16. A limit frame 17 is fixedly installed on the right side of the second infrared grating 16. A second telescopic cylinder 18 is fixedly installed on the outside of the limit frame 17. A limit plate 19 is fixedly installed at the front end of the second telescopic cylinder 18. A feeding rack 20 is fixedly installed on the right side. After the mold frame workpiece is centered, the drive controller 15 controls the second telescopic cylinder 18 to extend and retract, so that the two sets of limit plates 19 on the limit frame 17 are adjusted to a suitable distance and fit against the outside of the mold frame workpiece to limit the current conveying trajectory of the mold frame workpiece. The limit plates 19 are movably connected to the limit frame 17. The limit plates 19 are symmetrically arranged with respect to the central axis of the feeding rack 1. The limit plates 19 can accurately control the position of the workpiece, reduce the processing error caused by position deviation, and realize the automatic detection of the position and width of the workpiece and the automatic adjustment of the distance between the limit frames 17.

[0032] The working principle of this utility model is as follows: First, connect the external power supply and install the feeding mechanism of the mold frame processing equipment on one side. Then, adjust the height of the feeding frame 1 using the telescopic support frame 2 so that the feeding mechanism of the mold frame processing equipment is at the same height. Next, take out the mold frame workpiece to be processed and place it on the electric conveyor belt 4. The electric conveyor belt 4 will then start feeding. Since the first infrared grating 3 and the second infrared grating 16 are both connected to the drive controller 15, the position and width of the current mold frame workpiece will be detected after it passes through the first infrared grating 3 and the second infrared grating 16. The size is determined, and then the switch of the first telescopic cylinder 10 is turned on. The extension and retraction of the first telescopic cylinder 10 pushes the push block 9, thereby causing the first centering plate 13 to slide on the centering frame 6. Then, the first centering plate 13 slides towards the center of the centering frame 6. At this time, the push rack 11, which is meshed with the centering gear 12, also drives the second centering plate 14 to slide in the opposite direction and move towards the centering frame 6. In this way, the centering movement of the first centering plate 13 and the second centering plate 14 will straighten and center the mold frame workpiece that has passed through the centering frame 6 and whose position has been offset. This helps to ensure the accurate position of the mold frame workpiece in the subsequent processing. This design improves machining accuracy and centering, reducing workpiece swaying and offset during processing, enhancing stability, and minimizing machining errors and scrap rates caused by workpiece instability. After centering, the workpiece passes through the second infrared grating 16, and the drive controller 15 controls the second telescopic cylinder 18 to extend and retract. This adjusts the two sets of limit plates 19 on the limit frame 17 to a suitable distance, fitting against the outside of the workpiece and limiting its transport trajectory to maintain a centered position. This precise control of workpiece position reduces errors caused by positional deviations. This reduces processing errors and enables automatic detection of workpiece position and width, as well as automatic adjustment of the spacing of the limit frame 17, without the need for manual intervention, thus improving processing efficiency. Under the conveying of the feeding mechanism for mold frame processing, the mold frame workpiece is transported to the mold frame processing equipment in a centered position, and processing can begin directly. After completing the installation and use of all the feeding mechanisms for mold frame processing according to the above operations, turn off the switch of the first telescopic cylinder 10 and the switch of the second telescopic cylinder 18. If not used for a long time, simply disconnect the external power supply. In this way, the use process of the feeding mechanism structure used for mold frame processing is completed.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
