Description

Technical Field

[0001] The invention relates to the field of automobile parts processing, in particular to an automatic folding device for automobile plastic parts. Background Art

[0002] Automotive plastic parts refer to various plastic components used in the automobile manufacturing process, including: dashboard body frame, battery bracket, front end module, control box, seat support frame, spare tire seat, fender, chassis cover, sound insulation board, rear door frame, etc. These parts play an important role in the car, including but not limited to decoration, protection, function realization, etc.

[0003] Folding is a key process in the processing of automobile plastic parts. It can fold one part of the edge of the automobile plastic part inward and then match it with another part of the edge, which can enhance the pressure resistance of the automobile plastic part and improve the firmness and aesthetics of the packaging product. The existing Chinese public patent document: CN221697882U discloses an automatic folding device for automobile plastic parts. The folding claw is driven by a first driving component and a second driving component. When working, the folding claw is first driven by the second driving component to move forward, and the outer surface of the folding claw contacts the excess plastic and pushes the excess plastic forward; then the first driving component drives the folding claw to move forward. The first driving assembly lifts the hemming claw, and the second driving assembly continues to push the hemming claw forward so that the hemming claw reaches the hemming position of the plastic; the first driving assembly then drives the hemming claw downward to buckle the excess plastic back into the plastic part to achieve machine hemming. However, when the hemming claw pushes the part with more plastic, due to the elasticity of the plastic part, the plastic part will rebound when the hemming claw separates from the plastic part. If the top of the plastic part is not pressed down immediately, the hemming of the plastic part cannot be achieved, and due to the inertia of the rebound of the plastic part, the plastic part is easily offset and ejected from the mold.

[0032] The electric telescopic rod 8 can drive the folding pushing teeth 5 to move toward the side direction of the plastic part body 3 through the pushing plate 9, and drive the two connecting rods 14 to move synchronously through the pushing plate 9, so that the connecting rod 14 drives the mounting plate 12 to move downward, and the mounting plate 12 drives the guide rod 15 to move along the inner side of the guide cylinder 31 on the L-shaped bracket 4, so that the mounting plate 12 can move vertically downward.

[0033] The oblique pressing mechanism includes a side pressing plate 17 arranged on the left side of the lower pressing plate 6. The outer sides of the side pressing plate 17 and the lower pressing plate 6 are both made of rubber material to provide protection for the plastic body 3.

A groove for limiting sliding of the push rod 20 and the support slide 19 is provided on the outer side of the side pressing plate 17. One end of the rod 20 away from the mounting rod 18 is rotatably mounted on the bottom of the mounting plate 2 12, so that when the mounting plate 2 12 moves downward, the side pressure plate 17 can be pushed to contact the outer side of the plastic body 3 through the push rod 20 and the mounting rod 18. A sleeve frame 21 for limiting the sliding of the support slide 19 is fixedly mounted on the top of the mounting plate 10, and a slide bar 22 is fixedly mounted on the inner side of the sleeve frame 21.

An adjustment plate assembly for pressing the plastic body 3 at multiple angles is also provided on the inner side of the side pressure plate 17;

[0034] When the mounting plate 12 moves downward, the mounting rod 18 can be pushed to move by the push rod 20, and the mounting rod 18 drives the supporting slide bar 19 to move horizontally along the inner side of the sleeve frame 21, so that the mounting rod 18 can drive the side pressure plate 17 to be close to the outer side of the plastic part body 3, and when the side pressure plate 17 contacts the inclined surface of the plastic part body 3, the side pressure plate 17 can rotate along the outer side of the mounting rod 18, so that the side pressure plate 17 can smoothly press the inclined surface of the plastic part body 3 laterally, provide auxiliary thrust for the plastic part body 3, and facilitate the folding push teeth 5 to quickly fold the side edges of the plastic part body 3, thereby improving the accuracy of folding.

[0035] Working principle: First, the staff loads the plastic part body 3 to be processed into the mold seat 2, and then the staff starts the electric telescopic rod 8, so that the electric telescopic rod 8 pushes the push plate 9 to move, and the push plate 9 drives the folding edge pushing teeth 5 to move toward the side direction of the plastic part body 3.

The side pressure plate 17 is moved along the outer side of the plastic part body 3, and the side pressure plate 17 is rotated along the outer side of the mounting rod 18, so that the side pressure plate 17 can smoothly press the inclined surface of the plastic part body 3 laterally to provide auxiliary thrust for the plastic part body 3. Finally, the folding pushing teeth 5 are in contact with the side edge of the plastic part body 3, so that the folding pushing teeth 5 fold the side edge of the plastic part body 3. Under the pressing and positioning of the lower pressing plate 6 and the side pressure plate 17 on the plastic part body 3, the folding pushing teeth 5 can smoothly fold the plastic part body 3, thereby achieving the effect of smooth folding processing and improving the safety of folding processing of the plastic part body 3.

[0036] Example 2: Please refer to Figure 2-Figure 8, this embodiment further explains the first embodiment. The demoulding mechanism shown in the figure includes a plurality of equidistantly distributed air-exhausting chambers 23 opened on the inner sides of the mounting plate 10 and the lower pressing plate 6. The bottom end of the air-exhausting chamber 23 extends to the outer side of the lower pressing plate 6. The bottom end of the air-exhausting chamber 23 is a hollow truncated cone structure, which is convenient for rapid exhaust and adsorption of the plastic body 3. A piston block 24 is slidably installed on the inner side of the air-exhausting chamber 23. A piston rod 25 slidably extending to the top of the mounting plate 10 is fixedly installed on the top of the piston block 24. The air in the air-exhausting chamber 23 can be extracted through the piston block 24 by pulling the piston rod 25. A pull block 26 is fixedly installed on the top of the piston rod 25. L-shaped pull plates 27 are arranged on both sides of the pull block 26. The bottom of the L-shaped pull plate 27 is in contact with the pull plate 27. The top of the block 26 is a sloped structure, so that when the slope of the pull block 26 contacts the slope of the L-shaped pull plate 27, the L-shaped pull plate 27 can be pushed to move and the L-shaped pull plate 27 can be buckled on the bottom of the pull block 26. Two symmetrically distributed mounting rods 28 are rotatably installed on the inner side of the mounting plate 12. The end of the L-shaped pull plate 27 away from the piston block 24 is fixedly installed on the outer side of the mounting rod 28. A sliding groove for limiting the sliding of the L-shaped pull plate 27 is provided at the bottom of the mounting plate 12. A plurality of equidistantly distributed coil springs 38 are fixedly installed between the outer side of the mounting rod 28 and the inner side of the mounting plate 12 to facilitate the swinging and resetting of the L-shaped pull plate 27. An exhaust component for exhausting the air inside the vacuum chamber 23 is also provided on the inner side of the mounting plate 12.

[0037] In this embodiment: when the second mounting plate 12 moves downward, the second mounting plate 12 can drive the bottom inclined surface of the L-shaped pull plate 27 to contact the inclined surface at the top of the pull block 26, so that the L-shaped pull plate 27 drives the second mounting rod 28 to rotate and compresses the coil spring 38. The rebound force of the coil spring 38 is used to make the L-shaped pull plate 27 buckle at the bottom of the pull block 26. When the second mounting plate 12 moves upward, the L-shaped pull plate 27 can pull the pull block 26 to move upward, so that the pull block 26 drives the piston block 24 to move upward along the inner side of the vacuum chamber 23 through the piston rod 25. The bottom end of the vacuum chamber 23 can adsorb the plastic part body 3, which is convenient for the plastic part body 3 to be separated from the mold base 2, thereby achieving the effect of rapid demolding and facilitating the staff to take the material.

[0038] Example 3: Please refer to Figure 4 and Figure 5 This embodiment further explains other embodiments. The adjustment plate assembly shown in the figure includes two arc blocks 32 symmetrically fixedly installed at both ends of the mounting rod 18. An arc groove is provided on the inner side of the side pressure plate 17 for the arc block 32 to limit the sliding movement. Three arc rods 33 are fixedly installed on the inner side of the arc groove, which are evenly distributed and slide through the arc block 32. An arc spring 34 is provided on the outer side of the arc rod 33. The arc spring 34 is fixedly installed between the arc block 32 and the inner side of the arc groove. The elasticity of the arc spring 34 is used to facilitate the side pressure plate 17 to return to a vertical state.

[0039] In this embodiment: when the side pressure plate 17 contacts the outer side of the plastic component body 3, the arc spring 34 can be pressed through the arc groove therein, and the arc rod 33 can be driven to move along the inner side of the arc block 32. The elasticity of the arc spring 34 can facilitate the side pressure plate 17 to provide auxiliary thrust, so that the plastic component body 3 can be smoothly contacted with the folding edge pushing teeth 5. When the side pressure plate 17 is away from the plastic component body 3, the rebound force of the arc spring 34 can be utilized to enable the side pressure plate 17 to be quickly reset and to be in a horizontal state, so as to facilitate the positioning of the next plastic component body 3 and to facilitate the pressing and positioning of plastic component bodies 3 with different inclinations.

[0040] Example 4: Please refer to Figure 2-Figure 8 This embodiment further illustrates other embodiments. The exhaust assembly shown in the figure includes two gears 35 symmetrically fixedly mounted on both ends of the mounting rod 28. Two symmetrically distributed positioning plates 36 are fixedly mounted on the top inner wall of the L-shaped bracket 4. A rack matching the gear 35 is provided on the outer side of the positioning plate 36, so that when the gear 35 is close to the positioning plate 36, the gear 35 can be driven to rotate through the rack, so that the mounting rod 28 drives the L-shaped pull plate 27 away from the pull block 26. An annular protrusion is provided on the outer side of the piston rod 25, and a tension spring 37 is fixedly installed between the annular protrusion and the mounting plate 10, so as to facilitate the downward movement of the piston rod 25 and enable the piston block 24 to discharge the air in the suction chamber 23.

[0041] In this embodiment: when the second mounting plate 12 moves upward, it can drive the gear 35 on the second mounting rod 28 to contact the gear 35 on the positioning plate 36. As the second mounting plate 12 moves, the rack on the positioning plate 36 drives the gear 35 to rotate, and the gear 35 can drive the L-shaped pull plate 27 away from the pull block 26 through the second mounting rod 28. At this time, the rebound force of the tension spring 37 is used to drive the piston rod 25 to move downward, so that the piston rod 25 discharges the air in the suction chamber 23 through the piston block 24, thereby realizing the automatic resetting of the piston block 24, which is convenient for adsorbing the next plastic component body 3.
