[0003] Currently, the automotive market is increasingly demanding personalized and diversified parts, and the rapid pace of vehicle model updates is leading to a continuous increase in the types and specifications of injection-molded parts. Existing trimming equipment often only trims injection-molded products for specific automotive models. Furthermore, trimming automotive injection-molded products requires workers to perform multiple clamping and disassembly operations before and after trimming. The clamping accuracy heavily relies on the worker's experience and skill, making it difficult to guarantee consistency and stability. Any clamping misalignment during the trimming process will directly result in dimensional deviations in the trimmed parts, causing batch scrap and severely impacting product yield and production efficiency.

[0004] To address these issues, we provide a trimming device for injection molding automotive parts. Utility Model Content

A drive assembly for intermittently rotating the turntable 5 is located inside the lower end of the mounting housing 1. The drive assembly includes a cam divider 24, which is installed in the middle of the upper surface inside the mounting housing 1. The output shaft of the cam divider 24 is fixedly connected to the center of the turntable 5. A drive motor is installed on the connection port of the cam divider 24, and the output end of the drive motor is connected to the input shaft of the cam divider 24. During operation, the drive motor drives the internal components of the cam divider 24 to rotate. The rotation of the internal components of the cam divider 24 drives the turntable 5 to move intermittently, thereby realizing the switching of the turntable 5's work position.

[0026] The mounting housing 1, located inside the upper housing 4, is equipped with a fixing component for securing the injection-molded product. This fixing component includes two second electric cylinders 23, which are fixedly connected to opposite sides of the mounting housing 1. A lifting frame 15 is fixedly connected to the output end of each second electric cylinder 23. A sliding arm 20 is positioned above the lifting frame 15, and a fixed top rod 21 is fixedly connected to the end of the sliding arm 20. An adjustment component for adjusting the position of the fixed top rod 21 is located at the upper end of the lifting frame 15. When securing the injection-molded product, the output end of the second electric cylinder 23 moves, causing the lifting frame 15 to descend. The lifting frame 15 then simultaneously lowers the sliding arm 20 and the fixed top rod 21, using the fixed top rod 21 to secure the injection-molded product within the mold groove of the contour module 6, preventing the product from shaking during trimming.

[0027] The adjustment assembly includes a rotating sleeve 22, which is fixedly connected to the upper end of the lifting frame 15. A rotating column 17 is rotatably connected inside the rotating sleeve 22. The rotating sleeve 22 is provided with a first locking knob 16 for locking the rotation angle of the rotating column 17. A sliding sleeve 18 is fixedly connected to the upper end of the rotating column 17. The sliding sleeve 18 is slidably connected to the sliding arm 20. A second locking knob 19 is provided at the upper end of the sliding sleeve 18 for locking the position of the sliding arm 20. When it is necessary to adjust the angle of the sliding arm 20, the first locking knob 16 can be loosened first, and then the sliding sleeve 18 can be rotated for adjustment. After the adjustment is completed, the first locking knob 16 can be used to lock it. When it is necessary to adjust the position of the fixed top rod 21, the second locking knob 19 can be loosened first, and then the sliding arm 20 can be slid for corresponding adjustment. After the adjustment is completed, the second locking knob 19 can be used to lock the sliding arm 20.

[0028] The upper end of the upper housing 4 is also fixedly connected to an I-shaped top frame 8. The I-shaped top frame 8 is equipped with a trimming component for trimming injection molded products. The trimming component includes a first electric cylinder 11, which is fixedly connected to the middle of the I-shaped top frame 8. A transverse lead screw module 9 is fixedly connected to the output end of the first electric cylinder 11. Both ends of the transverse lead screw module 9 are fixedly connected to limit slide rods 12, which are slidably connected to the I-shaped top frame 8. The actuating end of the transverse lead screw module 9 is fixed. A longitudinal lead screw module 10 is connected, and a rotary motor 13 is installed at the actuating end of the longitudinal lead screw module 10. A trimming blade 14 is installed at the output end of the rotary motor 13. During trimming, the rotary motor 13 drives the trimming blade 14 to rotate. Then, the longitudinal lead screw module 10 drives the rotary motor 13 to move longitudinally, and the transverse lead screw module 9 drives the rotary motor 13 to move laterally. The first electric cylinder 11 drives the rotary motor 13 to move up and down, which in turn drives the trimming blade 14 to perform corresponding movements to achieve the trimming work of the injection molded product.

[0029] The mounting housing 1 is also rotatably connected to a door on one side, and the door is equipped with a door lock to fix it to the mounting housing 1; the upper housing 4 is provided with an observation glass 3 above the bottom opening 2; the contouring module 6 is fixedly connected to both sides of the mounting side seat 7, and the two ends of the mounting side seat 7 are connected to the upper end face of the turntable 5 with screws; the contouring module 6 is detachably connected to the turntable 5 with screws, so that the appropriate contouring module 6 can be replaced according to the type of product during use, so as to realize the trimming work of different products, and thus realize the trimming of multiple models of products, which is highly practical.

[0030] The working principle of this utility model is as follows: During operation, the product to be trimmed is placed in the contouring module 6, and then the drive motor drives the internal components of the cam divider 24 to rotate. The rotation of the internal components of the cam divider 24 can drive the turntable 5 to move intermittently, thereby realizing the station change of the turntable 5. When the injection molded product moves to the bottom of the trimming blade 14, the output end of the second electric cylinder 23 moves to drive the lifting frame 15 to descend. The lifting frame 15 drives the sliding arm 20 and the fixed top rod 21 to descend simultaneously. The fixed top rod 21 fixes the injection molded product in the mold groove of the contouring module 6. Then, the rotary motor 13 drives the trimming blade 14 to rotate. Then, the longitudinal lead screw module 10 drives the rotary motor 13 to move longitudinally, and the transverse lead screw module 9 drives the rotary motor 13 to move laterally. The first electric cylinder 11 drives the rotary motor 13 to move up and down, thereby driving the trimming blade 14 to move accordingly to realize the trimming work of the injection molded product.

[0031] After the contouring module 6 is replaced, the fixed position of the fixed ejector pin 21 can be adjusted according to the shape of the injection molded product to achieve a good fixing effect. When adjusting, first loosen the first locking knob 16, then rotate the sliding sleeve 18 to adjust. After adjustment, lock the first locking knob 16. When it is necessary to adjust the position of the fixed ejector pin 21, first turn the second locking knob 19 and then slide the sliding arm 20 to adjust accordingly. After adjustment, lock the sliding arm 20 with the second locking knob 19. Thus, the position of the fixed ejector pin 21 can be adjusted according to the shape of the injection molded product to achieve stable fixing of different products.

[0032] All electrical control components in this invention are controlled by a programmable controller. The connection circuits and control programs can be easily edited by those skilled in the art, and will not be described in detail here.
