Description

Technical Field

[0001] This utility model relates to the field of automotive parts mold processing technology, specifically a flipping device for automotive parts mold processing. Background Technology

[0002] Automotive parts molds are specialized tools used to manufacture automotive parts. By injecting or pressing material into the mold cavity, parts of the required shape and size are formed. A flipping device is required during the processing of automotive parts molds.

[0003] Existing automotive parts mold processing flipping devices typically place the automotive parts mold on a worktable, adjust the height of the clamping structure using an electric push rod, then move the two clamping plates of the clamping structure to the ends of the automotive parts mold, and then rotate the knob of the clamping structure to drive the bidirectional screw to rotate, causing the two clamping plates to move closer to the automotive parts mold until the clamping plates clamp the automotive parts mold. However, in use, the clamping plates of existing clamping structures can only clamp a single automotive parts mold and cannot effectively clamp automotive parts molds of different shapes. Utility Model Content

[0004] The purpose of this utility model is to provide a flipping device for processing automotive parts molds, which solves the problem that the clamping structure of existing flipping devices for processing automotive parts molds cannot effectively clamp automotive parts molds of different shapes.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a flipping device for processing automotive parts molds, comprising a worktable, a placement plate on the upper surface of the worktable, electric push rods at both ends of the worktable, connecting plates mounted on the output ends of the two electric push rods, and clamping structures at one end of the two connecting plates. Each clamping structure includes a rectangular block with a groove on its outer surface. Two first sliders are slidably connected inside the groove. A connecting block is located at one end of each first slider. A base plate is mounted on the lower surface of the connecting block, and several through holes are formed on the upper surface of the connecting block. A first spring is installed inside each through hole, with one end of the first spring mounted on the upper surface of the base plate and the other end of the first spring mounted on a telescopic rod slidably connected inside the through hole.

[0007] Furthermore, a side plate is installed at one end of the rectangular block, and a bidirectional screw is rotatably connected to the inner surface of the groove. One end of the bidirectional screw passes through the side plate and is equipped with a rotating handle. Both of the first sliders are threadedly connected to the outer surface of the bidirectional screw.

[0008] Furthermore, mounting holes are provided on the outer surfaces of both connecting plates, and rotating shafts are rotatably connected inside the two mounting holes. One end of each rotating shaft is mounted on the outer surface of the rectangular block. A driven gear is mounted on the other end of one of the rotating shafts. A drive motor is mounted on the upper surface of one of the connecting plates, and a driving gear is mounted on the output end of the drive motor. The driving gear meshes with the driven gear.

[0009] Furthermore, a support column is installed on the lower surface of the workbench, and support seats are installed at both ends of the workbench. The two electric push rods are installed on the upper surface of the corresponding support seats.

[0010] Furthermore, the upper surface of the workbench is provided with a placement groove, the bottom of the placement groove is provided with a sliding groove, a guide rod is installed inside the sliding groove, a second slider is slidably connected to the outer surface of the guide rod, a second spring is sleeved on the outer surface of the guide rod, one end of the second spring is installed on the inner surface of the sliding groove, the other end of the second spring is installed on the outer surface of the second slider, one end of the second slider is located inside the sliding groove and moves along the axis of the sliding groove, the lower surface of the placement plate is provided with an installation groove, an installation block is installed inside the installation groove, a connecting rod is hinged to the lower surface of the installation block, and the other end of the connecting rod is hinged to the upper surface of the second slider.

[0011] Furthermore, a damping shock absorber is installed at the bottom of the placement groove, and the other end of the damping shock absorber is installed on the lower surface of the placement plate.

[0012] This utility model has the following beneficial effects:

[0013] (1) This utility model uses the independent elastic design of multiple telescopic rods to enable the clamping force to be dynamically adjusted according to the shape of the mold surface. If a certain area of ​​the mold is higher, the corresponding telescopic rod will be compressed more and the spring force will increase, while the telescopic rod in the lower area will be compressed less and the spring force will be smaller, thus automatically balancing the overall clamping force. For asymmetrical or curved molds, the independent movement capability of the telescopic rods can adapt to the irregular contour of the mold surface, ensuring multi-point contact and stable clamping, avoiding the slippage problem caused by the single contact surface of the traditional rigid clamping structure, and achieving a better clamping effect.

[0014] (2) When the mold of this utility model is placed on the placement plate, the weight of the mold will exert downward pressure, causing the placement plate to move downward. The mounting block on the lower surface of the placement plate moves downward accordingly, and the vertical downward pressure is converted into horizontal force through the hinged connecting rod, pushing the second slider to slide along the guide rod to one side of the slide groove. When the second slider slides, it will compress the second spring sleeved on the guide rod. The elastic deformation of the second spring absorbs the energy of the mold pressing down, achieving a buffering effect.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4As shown, this utility model is a flipping device for processing automotive parts molds, including a worktable 1, a placement plate 2 on the upper surface of the worktable 1, electric push rods 3 at both ends of the worktable 1, connecting plates 4 installed at the output ends of the two electric push rods 3, and clamping structures 5 at one end of the two connecting plates 4. The clamping structure 5 includes a rectangular block 501, a groove is formed on the outer surface of the rectangular block 501, two first sliders 502 are slidably connected inside the groove, a connecting block 503 is provided at one end of the first slider 502, a base plate 504 is installed on the lower surface of the connecting block 503, a plurality of through holes are formed on the upper surface of the connecting block 503, a first spring 505 is provided inside the through holes, one end of the first spring 505 is installed on the upper surface of the base plate 504, and a telescopic rod 506 is installed at the other end of the first spring 505, which is slidably connected inside the through holes.

[0025] Through the independent elastic design of multiple telescopic rods 506, the clamping force can be dynamically adjusted according to the shape of the mold surface. If a certain area of ​​the mold is higher, the corresponding telescopic rod 506 will be compressed more, and the spring force will increase. In contrast, the telescopic rod 506 in the lower area will be compressed less, and the spring force will be smaller. This automatically balances the overall clamping force. For asymmetrical or curved molds, the independent movement capability of the telescopic rods 506 can adapt to the irregular contours of the mold surface, ensuring multi-point contact and stable clamping. This avoids the slippage problem caused by the single contact surface in traditional rigid clamping structures, resulting in a better clamping effect.

[0026] A side plate 507 is installed at one end of a rectangular block 501. A bidirectional screw 508 is rotatably connected to the inner surface of the groove. One end of the bidirectional screw 508 passes through the side plate 507 and is equipped with a rotating handle 509. Both first sliders 502 are threadedly connected to the outer surface of the bidirectional screw 508.

[0027] The outer surfaces of the two connecting plates 4 are provided with mounting holes, and the interiors of the two mounting holes are rotatably connected to rotating shafts 6. One end of each rotating shaft 6 is mounted on the outer surface of the rectangular block 501. The other end of one of the rotating shafts 6 is equipped with a driven gear 7. The upper surface of one of the connecting plates 4 is equipped with a drive motor 8. The output end of the drive motor 8 is equipped with a driving gear 9, which meshes with the driven gear 7.

[0028] A support column 10 is installed on the lower surface of the workbench 1, and support seats 11 are installed at both ends of the workbench 1. Two electric push rods 3 are installed on the upper surface of the corresponding support seats 11.

[0029] The upper surface of the workbench 1 is provided with a placement groove 101, and the bottom of the placement groove 101 is provided with a sliding groove. A guide rod 12 is installed inside the sliding groove. A second slider 13 is slidably connected to the outer surface of the guide rod 12. A second spring 14 is sleeved on the outer surface of the guide rod 12. One end of the second spring 14 is installed on the inner surface of the sliding groove, and the other end of the second spring 14 is installed on the outer surface of the second slider 13. One end of the second slider 13 is located inside the sliding groove and moves along the axis of the sliding groove. The lower surface of the placement plate 2 is provided with an installation groove. An installation block 15 is installed inside the installation groove. A connecting rod 16 is hinged to the lower surface of the installation block 15. The other end of the connecting rod 16 is hinged to the upper surface of the second slider 13.

[0030] When the mold is placed on the placement plate 2, the weight of the mold will exert downward pressure, causing the placement plate 2 to move downward. The mounting block 15 on the lower surface of the placement plate 2 moves downward accordingly, and the vertical downward pressure is converted into a horizontal force through the hinged connecting rod 16, which pushes the second slider 13 to slide along the guide rod 12 to one side of the slide groove. When the second slider 13 slides, it will compress the second spring 14 sleeved on the guide rod 12. The elastic deformation of the second spring 14 absorbs the energy of the mold pressing down, achieving a buffering effect.

[0031] A damping shock absorber 17 is installed at the bottom of the placement slot 101, and the other end of the damping shock absorber 17 is installed on the lower surface of the placement plate 2.

[0032] During the pressing down of the placement plate 2, the damping shock absorber 17 is compressed simultaneously. Its internal damping medium generates resistance through the throttling orifice, quickly dissipating vibration energy and preventing the placement plate 2 from continuously oscillating due to the spring rebound force.

[0033] In use, first place the mold on the placement plate 2, so that the clamping structure 5 is located at both ends of the mold. By rotating the rotary handle 509, the first slider 502 moves towards the middle, causing the connecting block 503 to drive the telescopic rod 506 closer to the mold, thus clamping the mold. During the clamping process, after the mold contacts the telescopic rod 506, it applies pressure to the telescopic rod 506, compressing the first spring 505. Through the independent elastic design of multiple telescopic rods 506, the clamping force can be dynamically adjusted according to the shape of the mold surface. If a certain area of ​​the mold is higher, the corresponding telescopic rod 506 will be compressed more, and the spring force will increase, while the telescopic rod 506 in the lower area will be compressed less, and the spring force will be smaller, thus automatically balancing the overall clamping force. For asymmetrical or curved molds, the independent movement capability of the telescopic rod 506 can adapt to the irregular contour of the mold surface, ensuring multi-point contact and stable clamping, avoiding the slippage problem caused by the single contact surface of traditional rigid clamping structures, and clamping the mold well. Then, the electric push rod 3 is activated, causing its output end to move the connecting plate 4 upward. This allows the mold to rise and detach from the clamping structure 5, and the placement plate 2 to release its contact. The drive motor 8 is then activated, causing its output end to rotate via the drive gear 9. Since the drive gear 9 meshes with the driven gear 7, the driven gear 7 drives the clamping structure 5 and the mold on it to flip via the rotating shaft 6. When the mold is placed on the placement plate 2, its weight exerts downward pressure, causing the placement plate 2 to move downward. The mounting block 15 on the lower surface of the placement plate 2 moves downward accordingly, and the vertical downward pressure is converted into a horizontal force via the hinged connecting rod 16. This force pushes the second slider 13 to slide along the guide rod 12 towards one side of the groove. As the second slider 13 slides, it compresses the second spring 14 sleeved on the guide rod 12. The elastic deformation of the second spring 14 absorbs the energy of the mold's downward pressure, achieving a buffering effect.
