Description

Technical Field

[0001] This invention relates to the field of injection molding mold technology, and in particular to an injection molding mold for automotive lidar trim panels. Background Technology

[0002] Automotive lidar trim panels are key components installed on the exterior of lidar sensors. They primarily protect the lidar sensor, optimize optical performance (such as light transmission and anti-reflection), and meet the overall vehicle exterior design requirements. The injection molds used for these panels must possess high precision, high surface quality, and stable mass production capabilities to ensure the product meets automotive-grade standards.

[0003] The prior art publication CN213198637U provides an injection molding mold for a lidar device housing. By using a filter box, activated carbon adsorption plate, and exhaust fan, toxic gases generated during the injection molding process can be filtered and discharged to avoid harming workers' health and preventing environmental pollution. By using a metal cylinder, support rod, and vibration motor, the gap between the injection punch and die can be finely adjusted, while ensuring that the injected plastic is evenly covered between the punch and die, thereby improving the yield of injection molded products.

[0004] In the use of existing technologies, defective automotive lidar trim panels may occur during the injection molding process. However, current technologies are not conducive to the timely sorting and recycling of these defective products, which may result in them being mixed with qualified products, increasing the difficulty of subsequent processing and recycling. Due to the lack of an effective sorting and recycling mechanism, defective products may be wasted and not fully recycled, increasing production costs.

[0005] In summary, the existing technology lacks a method for sorting and recycling defective automotive lidar trim panels. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by proposing an injection molding mold for automotive lidar trim panels.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an injection molding mold for automotive laser radar trim panels, comprising a worktable, an injection mold fixedly mounted on the worktable, a conveyor frame fixedly connected to one side of the worktable, a conveyor belt rotatably connected inside the conveyor frame, a plurality of trim panel placement seats fixedly connected to the conveyor belt, a take-up and release mechanism rotatably connected to the outside of the trim panel placement seats, a pusher frame on one side of the conveyor frame, a crushing and recycling seat fixedly connected to the other side of the conveyor frame, and a transmission mechanism rotatably connected to one side of the conveyor frame.

[0008] Preferably, a material receiving groove is fixedly connected to the lower side of the workbench.

[0009] Preferably, the inner walls at both ends of the conveyor belt are equipped with pulleys for friction drive, and the pulleys are rotatably connected to the conveyor frame. One end of one of the pulleys extends through the inner wall of the conveyor frame to the outside and is fixedly connected to a motor. The motor is fixedly connected to the conveyor frame, and the other end of the pulley is fixedly connected to a drive wheel.

[0010] Preferably, a positioning block is slidably fitted inside the trim panel placement seat, and an automotive LiDAR trim panel is placed on the positioning block. Multiple tension springs A are fixedly connected to the bottom of the positioning block, and the other end of each tension spring A is fixedly connected to the inner wall of the trim panel placement seat.

[0011] Preferably, the retractable mechanism includes a worm gear, which is rotatably connected to the outer wall of the trim panel placement seat. A transmission gear is fixedly connected to the top of the worm gear, and the transmission gear meshes with a transmission rack. A worm wheel is meshed with one side of the worm gear, and an L-shaped top rod is fixedly connected to one end of the worm wheel. The L-shaped top rod is rotatably connected to the inner wall of the trim panel placement seat, and one end of the L-shaped top rod is in sliding contact with the lower surface of the positioning block.

[0012] Preferably, an electric push rod A is fixedly connected to one end of the pusher frame, the electric push rod A is fixedly connected to the conveyor frame, and a transmission rack is fixedly connected to one end of the pusher frame.

[0013] Preferably, a cover plate is rotatably connected to the top opening of the crushing and recycling seat, and adjusting wheels are fixedly connected to both ends of the cover plate. A contact frame is slidably fitted on the crushing and recycling seat. Adjusting racks are fixedly connected to both ends of one side of the contact frame. The adjusting racks are meshed with the adjusting wheels for transmission. An inclined surface is opened at the other end of the contact frame. The inclined surface of the contact frame is slidably in contact with the pusher frame. A spring is fixedly connected between the contact frame and the crushing and recycling seat.

[0014] Preferably, the inner wall of the crushing and recycling seat has two crushing rollers that are symmetrically connected and rotated through it. The outer ends of the crushing rollers are fixedly connected with gears, and the two gears are meshed and driven.

[0015] Preferably, the transmission mechanism includes a swing rod, one end of which has a groove. An L-shaped push rod is slidably fitted on the inner wall of the groove. The L-shaped push rod is rotatably connected to the outer wall of the conveyor frame. An electric push rod B is fixedly connected to one end of the L-shaped push rod, and a driven wheel is fixedly connected to the other end of the electric push rod B. The driven wheel meshes with the driving wheel for transmission. A toothed disc is fixedly connected to the other end of the L-shaped push rod. A toothed disc is rotatably connected to the inner wall of the toothed disc. Multiple transmission teeth are meshed in a ring structure on the toothed disc. A tension spring B is fixedly connected between the transmission teeth and the toothed disc. The transmission teeth mesh with the grooves on the inner wall of the toothed disc for transmission. One end of the toothed disc extends through the inner wall of the toothed disc to the outside and is fixedly connected to the outer end of one of the crushing rollers.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. After the injection molding of the automotive lidar trim panel is completed, it is placed on the matching positioning block to facilitate the identification of defective products. By linking the positioning block, the take-up and put-down mechanism and the pusher, defective products can be automatically identified and processed, realizing efficient, automated and precise waste management and production control. This greatly improves production efficiency, safety and waste recycling rate, while reducing the risk of manual intervention, production interruption and equipment damage, thus making the injection molding process of automotive lidar trim panels more efficient, intelligent and environmentally friendly.

[0018] 2. By setting up a transmission mechanism, when defective automotive LiDAR trim panels need to be crushed and recycled, the transmission mechanism can automatically drive two crushing rollers to rotate while the conveyor belt is transporting the automotive LiDAR trim panels. This allows the crushing rollers to start automatically during the conveyor belt transport process, effectively improving production efficiency, reducing labor costs, optimizing waste recycling management, and enhancing the continuity and safety of the production process. It can ensure the efficient use of resources while improving production efficiency and enhancing the automation and precise control capabilities of the entire production system.

[0019] 3. By setting up a contact frame with an inclined surface, the contact frame can be moved upwards while the pusher pushes the automotive LiDAR trim panel, thereby automatically opening the cover plate on the crushing and recycling seat. This achieves fully automated cover plate opening and closing control, eliminating the need for manual operation of the cover plate by workers, greatly reducing manual intervention and improving production efficiency. When the pusher moves away, the cover plate automatically resets under the action of a spring, effectively preventing waste from splashing or overflowing during crushing, ensuring the cleanliness of the crushing and recycling area, and reducing environmental pollution.

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] like Figures 1-8 The illustrated automotive lidar trim panel injection molding mold includes a worktable 1, on which an injection mold 2 is fixedly mounted. A conveyor frame 3 is fixedly connected to one side of the worktable 1, and a conveyor belt 4 is rotatably connected inside the conveyor frame 3. Multiple trim panel placement seats 5 are fixedly connected to the conveyor belt 4, and a take-up and release mechanism 6 is rotatably connected to the outside of the trim panel placement seats 5. A pusher frame 7 is provided on one side of the conveyor frame 3, and a crushing and recycling seat 8 is fixedly connected to the other side of the conveyor frame 3. A transmission mechanism 9 is rotatably connected to one side of the conveyor frame 3. An ultrasonic sensor is mounted on the conveyor frame 3.

[0031] like Figure 3 As shown, a receiving groove 101 is fixedly connected to the lower side of the workbench 1.

[0032] like Figure 3 As shown, both ends of the conveyor belt 4 have friction-driven pulleys 401 on their inner walls. The pulleys 401 are rotatably connected to the conveyor frame 3. One end of one pulley 401 extends through the inner wall of the conveyor frame 3 to the outside and is fixedly connected to a motor 402. The motor 402 is fixedly connected to the conveyor frame 3, and the other end of the pulley 401 is fixedly connected to a drive wheel 403. When the motor 402 drives the pulley 401 to rotate, it also drives the drive wheel 403 to rotate. At this time, the drive wheel 403 drives the driven wheel 905 to rotate.

[0033] like Figure 4 As shown, a positioning block 501 is slidably fitted inside the trim panel placement seat 5. An automotive laser radar trim panel 502 is placed on the positioning block 501. Multiple tension springs A503 are fixedly connected to the bottom of the positioning block 501. The other end of the tension springs A503 is fixedly connected to the inner wall of the trim panel placement seat 5.

[0034] like Figure 5 As shown, the retractable mechanism 6 includes a worm gear 601, which is rotatably connected to the outer wall of the trim panel placement seat 5. A transmission gear 602 is fixedly connected to the top of the worm gear 601, and the transmission gear 602 meshes with the transmission rack 702. A worm wheel 603 is meshed with one side of the worm gear 601, and an L-shaped push rod 604 is fixedly connected to one end of the worm wheel 603. The L-shaped push rod 604 is rotatably connected to the inner wall of the trim panel placement seat 5, and one end of the L-shaped push rod 604 is in sliding contact with the lower surface of the positioning block 501. The pusher frame 7 is moved by the electric actuator A701. At this time, the transmission rack 702 on the pusher frame 7 will mesh with the transmission gear 602, so that the transmission gear 602 drives the connected worm 601 to rotate. Then the worm 601 will drive the L-shaped push rod 604 connected to the worm wheel 603 to rotate, so that the L-shaped push rod 604 is flattened. At this time, under the action of the tension spring A503, the positioning block 501 will be moved down and retracted.

[0035] like Figure 6 As shown, an electric push rod A701 is fixedly connected to one end of the pusher frame 7. The electric push rod A701 is fixedly connected to the conveyor frame 3. A transmission rack 702 is fixedly connected to one end of the pusher frame 7.

[0036] After the injection molding of the automotive lidar trim panel 502 is completed, it is placed on the matching positioning block 501 to facilitate the identification of defective products. By linking the positioning block 501, the take-up and take-down mechanism 6 and the pusher 7, defective products can be automatically identified and processed, realizing efficient, automated and precise waste management and production control. This greatly improves production efficiency, safety and waste recycling rate, while reducing the risk of manual intervention, production interruption and equipment damage. As a result, the injection molding process of the automotive lidar trim panel 502 is more efficient, intelligent and environmentally friendly.

[0037] like Figure 7 As shown, a cover plate 801 is rotatably connected to the top opening of the crushing and recycling seat 8. Adjusting wheels 802 are fixedly connected to both ends of the cover plate 801. A contact frame 803 is slidably fitted onto the crushing and recycling seat 8. Adjusting racks 804 are fixedly connected to both ends of one side of the contact frame 803, meshing with the adjusting wheels 802 for transmission. An inclined surface is provided at the other end of the contact frame 803, and this inclined surface slides in contact with the pusher frame 7. A spring 807 is fixedly connected between the contact frame 803 and the crushing and recycling seat 8. When the pusher frame 7 moves, it contacts and lifts the contact frame 803, causing the contact frame 803 to move the adjusting racks 804 at both ends. At this time, the adjusting racks 804 drive the adjusting wheels 802 to rotate, and then the adjusting wheels 802 automatically open the connected cover plate 801.

[0038] The inner wall of the crushing and recycling seat 8 has a symmetrical structure with two crushing rollers 805 rotatably connected through it. Gears 806 are fixedly connected to the outer ends of the crushing rollers 805, and the two gears 806 are meshed for transmission. The crushing roller 805 will drive the crushing roller 805 connected to the other gear 806 to rotate through the connected gear 806.

[0039] like Figure 8As shown, the transmission mechanism 9 includes a swing rod 901. One end of the swing rod 901 has a groove 902. An L-shaped push rod 903 is slidably fitted onto the inner wall of the groove 902. The L-shaped push rod 903 is rotatably connected to the outer wall of the conveyor frame 3. One end of the L-shaped push rod 903 is fixedly connected to an electric push rod B904, and the other end of the electric push rod B904 is fixedly connected to a driven wheel 905. The driven wheel 905 meshes with the driving wheel 403 for transmission. The other end of the L-shaped push rod 903 is fixed... A toothed disc 906 is fixedly connected, and a toothed disc 907 is rotatably connected to the inner wall of the toothed disc 906. Multiple transmission teeth 908 are arranged in a ring structure on the toothed disc 907 for meshing and transmission. A tension spring B909 is fixedly connected between the transmission teeth 908 and the toothed disc 907. The transmission teeth 908 mesh with the grooves on the inner wall of the toothed disc 906 for transmission. One end of the toothed disc 907 extends through the inner wall of the toothed disc 906 to the outside and is fixedly connected to the outer end of one of the crushing rollers 805. The swing rod 901 achieves lever transmission, which is more labor-saving, and the tension spring B909 enables unidirectional transmission of the transmission teeth 908. Driven wheel 905 drives L-shaped push rod 903 connected to electric push rod B904 to rotate, causing L-shaped push rod 903 to slide in slide groove 902, causing swing rod 901 to swing. At this time, swing rod 901 will drive toothed disc 906 to rotate, and then the toothed groove in toothed disc 906 will mesh with transmission tooth 908, thereby driving toothed disc 907 connected to transmission tooth 908 to rotate, so that toothed disc 907 drives the connected crushing roller 805 to rotate.

[0040] Working principle: After the automotive lidar trim panel 502 is injected into the injection mold 2, the automotive lidar trim panel 502 will fall into the receiving groove 101. Then, the automotive lidar trim panel 502 is manually placed on the positioning block 501 on the trim panel placement seat 5. Then, the ultrasonic sensor emits high-frequency sound waves, and the internal structure and surface defects of the automotive lidar trim panel 502 are detected by the time and intensity of the reflected echo.

[0041] When a defect is detected in the automotive lidar trim panel 502 and it is identified as a defective product, the conveyor belt 4 brings it to the pusher frame 7. The pusher frame 7 is moved by the electric push rod A701. At this time, the transmission rack 702 on the pusher frame 7 will mesh with the transmission gear 602, so that the transmission gear 602 drives the connected worm 601 to rotate. Then the worm 601 will drive the L-shaped push rod 604 connected to the worm wheel 603 to rotate, so that the L-shaped push rod 604 is flattened. At this time, under the action of the tension spring A503, the positioning block 501 will move down and retract, so that the pusher frame 7 can push the automotive lidar trim panel 502.

[0042] Simultaneously, when the pusher 7 moves, it will contact and push up the contact frame 803, so that the contact frame 803 can drive the adjusting racks 804 at both ends to move. At this time, the adjusting racks 804 will drive the adjusting wheel 802 to rotate, and then the adjusting wheel 802 will drive the connected cover plate 801 to open automatically, so that the car laser radar trim panel 502 can fall into the crushing and recycling seat 8. When the pusher 7 retracts, under the action of the spring 807, it will drive the contact frame 803 to move down, so that the cover plate 801 will automatically reset.

[0043] Then, the electric actuator B904 drives the driven wheel 905 to move, so that the driven wheel 905 meshes with the driving wheel 403. At the same time, the motor 402 drives the pulley 401 to rotate, which in turn drives the driving wheel 403 to rotate. At this time, the driving wheel 403 drives the driven wheel 905 to rotate, so that the driven wheel 905 drives the L-shaped actuator 903 connected to the electric actuator B904 to rotate, so that the L-shaped actuator 903 slides in the slide groove 902, causing the swing rod 901 to swing. At this time, the swing rod 901 drives the toothed disc 906 to rotate, and then the toothed groove in the toothed disc 906 meshes with the transmission gear 908, thereby driving the toothed disc 907 connected to the transmission gear 908 to rotate. The toothed disc 907 drives the connected crushing roller 805 to rotate. At this time, the crushing roller 805 drives another crushing roller 805 connected to the gear 806 to rotate through the connected gear 806, thus crushing the defective automotive laser radar trim panel 502.
