Technical Field

[0001] This utility model relates to the field of automotive interior parts processing technology, and in particular to a gate shearing device for automotive interior injection molded parts. Background Technology

[0002] In the production of automotive interior parts, many plastic components are formed using injection molding. During injection molding, molten plastic enters the mold through a gate, cools, and solidifies to form the final plastic part. These parts typically have gates, which need to be cut off to ensure the part's appearance and function. Many automotive interior parts, such as dashboards, door panels, and seat components, are injection molded. Gates are left behind during the injection molding process and need to be cut off to meet design requirements and appearance standards. Gate cutting devices are particularly important in this stage.

[0003] However, some existing gate cutting devices for automotive interior injection molding parts typically clamp and fix the injection molding parts directly, and then cut their gates. However, they do not take into account the errors that may occur during each injection process when producing automotive interior injection molding parts, which can lead to inconsistent gate lengths. Therefore, it is necessary to adjust the cutting blade to cut according to the actual length of the gate.

[0004] Therefore, a gate shearing device for automotive interior injection molded parts is proposed to address the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a gate shearing device for automotive interior injection molded parts, which aims to improve the problem that the position of the shearing blade cannot be flexibly adjusted in the prior art.

[0032] Reference Figures 1 to 2This utility model provides an embodiment of a gate shearing device for automotive interior injection molded parts, including a worktable 1. Support columns 2 are fixedly connected to the top left and right sides of the worktable 1, thus providing support for the multiple support columns 2. Support legs are fixedly connected to the four corners of the bottom of the worktable 1, providing support for the worktable 1. Moving components for moving the shearing position are fixedly connected to the top of each support column 2, thus providing support for the moving components. Sliding blocks 3 are slidably connected to the outside of the moving components, thereby activating the moving components. The moving component enables the sliding block 3 to move. The moving component includes two electric guide rails 14. The bottom left and right sides of the electric guide rails 14 are fixedly connected to the top of two support columns 2, so that the support columns 2 can provide support for the electric guide rails 14. The middle parts of the two sliding blocks 3 are slidably connected to the outside of the two electric guide rails 14. Then, starting the electric guide rails 14 can enable the electric guide rails 14 to drive the sliding block 3 to move. The top of one of the sliding blocks 3 is fixedly connected to a drive component for providing power to the device, so that the sliding block 3 can provide support for the drive component.

[0033] The drive assembly has a sliding block 2 6 connected to its external thread. Activating the drive assembly allows it to move the sliding block 2 6. The drive assembly includes a motor 4, the bottom of which is fixedly connected to the top of one of the sliding blocks 1 3, thus providing support for the motor 4. A threaded rod 5 is fixedly connected to the output end of the motor 4, so activating the motor 4 causes the threaded rod 5 to rotate. The bottom of the sliding block 2 6 is threadedly connected to the outside of the threaded rod 5, so rotating the threaded rod 5 causes the sliding block 2 6 to move. An electric push rod 1 7 is fixedly connected to the bottom of the sliding block 2 6, so moving the sliding block 2 6 causes the electric push rod 1 7 to move.

[0034] The output end of the electric push rod 7 is fixedly connected to the mounting plate 8, and the bottom of the mounting plate 8 is fixedly connected to the cutting blade 9. When the electric push rod 7 is activated, the output end of the electric push rod 7 drives the cutting blade 9 to rise and fall through the mounting plate 8, thereby enabling the cutting blade 9 to cut the gate. The top of the two sliding blocks 3 is fixedly connected to the support plate 10, so that the sliding block 3 can provide support for the support plate 10. The adjacent side of the two support plates 10 is fixedly connected to the fixing rod 11, so that the support plate 10 can provide support for the fixing rod 11. The top of the sliding block 6 is slidably connected to the outside of the fixing rod 11, so that the fixing rod 11 can provide a limit when the sliding block 6 moves.

[0035] Reference Figure 1 , Figure 3 and Figure 4A mounting base 15 is fixedly connected to the top right side of the workbench 1, thus providing support for the mounting base 15. An electric push rod 16 is fixedly connected to the top of the mounting base 15, thus providing support for the electric push rod 16. A cleaning plate 17 is fixedly connected to the output end of the electric push rod 16. Activating the electric push rod 16 will cause the output end of the electric push rod 16 to drive the cleaning plate 17 to move. Limiting plates 18 are fixedly connected to the front and rear sides of the top of the workbench 1. Limiting rods 19 are fixedly connected to the top of the two limiting plates 18, thus providing support for the limiting rods 19. The front and rear sides of the top of the cleaning plate 17 are slidably connected to the outside of the two limiting rods 19, thus providing a limit when the cleaning plate 17 moves.

[0036] The bottom of the cleaning plate 17 contacts the top of the workbench 1, and the front and rear sides of the cleaning plate 17 contact the adjacent side of the two limiting plates 18. When the cleaning plate 17 moves, it can clean the debris generated by shearing on the top of the workbench 1. The front and rear sides of the top of the workbench 1 are fixedly connected to the mounting base 20, so that the workbench 1 can provide support for the mounting base 20. The top of the two mounting bases 20 are fixedly connected to the electric push rods 23, so that the mounting bases 20 can provide support for the electric push rods 23. The output ends of the two electric push rods 23 are fixedly connected to the clamping plates 12. When the electric push rods 213 are activated, they can drive the clamping plates 12 to clamp and fix them, thereby preventing the automotive interior injection molded parts from shaking when the device shears the gate of the automotive interior injection molded parts.

[0037] Working principle: When the position of the cutting blade 9 needs to be adjusted according to the length of the gate, the electric guide rail 14 in the moving assembly is activated, causing the sliding block 3 to move along the guide rail. When the sliding block 3 moves to the appropriate position, the motor 4 in the drive assembly is activated. After the motor 4 starts, its output end drives the threaded rod 5 to rotate. When the threaded rod 5 rotates, it drives the sliding block 6 to move. When the sliding block 6 moves, it drives the cutting blade 9 to move. When the position of the cutting blade 9 is adjusted, the electric push rod 7 is activated. The output end of the electric push rod 7 drives the cutting blade 9 to descend through the mounting plate 8. When the cutting blade 9 descends to contact the gate of the automotive interior injection molded part, it will perform a shearing operation on the gate.

[0038] Before shearing, the electric push rod 13 can be activated to clamp the automotive interior injection molded part with the clamping plate 12. This prevents the automotive interior injection molded part from shaking when the device shears the gate of the automotive interior injection molded part, ensuring the smooth progress and quality of the shearing work.

[0039] After the injection molding gate of the automotive interior parts is cut, debris generated during cutting will remain on the top of the worktable 1. At this time, the electric push rod 16 is activated. After the electric push rod 16 is activated, its output end will drive the cleaning plate 17 to move on the top of the worktable 1. The limiting rod 19 can provide a limit when the cleaning plate 17 moves, ensuring that the cleaning plate 17 can move along the prescribed path. The bottom of the cleaning plate 17 is in contact with the top of the worktable 1, and the front and rear sides of the cleaning plate 17 are in contact with the adjacent side of the two limiting plates 18. When the cleaning plate 17 moves, it can clean the debris generated by cutting on the top of the worktable 1, improving the ease of use of the device.
