[0033] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0034] In addition, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0035] Refer to Figures 1 to 4, which is the first embodiment of the present utility model, proposes a die flipping and clamping device for flipping the upper die 2 on the conveying member 1, including: a frame body 3, the conveying member 1 passes through the frame body 3; a flipping frame 4 is rotatably arranged on the frame body 3, and a passing space 5 is provided on the flipping frame 4, the conveying member 1 passes through the passing space 5, the flipping frame 4 is annular and has teeth 6 on its side wall; a gear 9 is rotatably arranged on the frame body 3, the gear 9 meshes with the teeth 6, and the gear 9 is used to drive the flipping frame 4 to rotate.

[0036] In this embodiment, during operation, the conveying device conveys the upper die 2 onto the flipping frame 4. After the upper die 2 is fixed on the flipping frame 4, the flipping frame 4 rotates, thereby driving the upper die 2 to flip. The first rotation driving member 7 is a motor, and can also be a workpiece such as an electric motor that can drive the gear 9 to rotate. When the first rotation driving member 7 rotates, the gear 9 will be driven to rotate synchronously. The first rotation driving member 7 drives the flipping frame 4 to rotate by meshing the gear 9 with the teeth 6 of the flipping frame 4. This transmission method has high precision, can achieve precise control of the flipping angle, and ensures the quality and reliability of clamping. At the same time, the gear 9 transmission method will not cause a large change in control precision even if it wears during long-term operation, improving the service life. This die flipping and clamping device can quickly and accurately flip the upper die 2 on the conveying member 1, reducing the time and labor intensity of manual operation and greatly improving production efficiency.

[0037] As a further technical solution, there are a plurality of receiving plates 10, which are arranged on the flipping frame 4. There is a receiving space 11 between the plurality of receiving plates 10, and the receiving space 11 is used to receive the upper die 2.

[0038] In this embodiment, a plurality of receiving plates 10 are arranged on the flipping frame 4, providing stable receiving support for the upper die 2. During the flipping process, the upper die 2 can be stably placed in the receiving space 11, effectively preventing the upper die 2 from slipping or shaking, ensuring the safety and reliability of the flipping operation. The design of multiple receiving plates 10 increases the contact area with the upper die 2, further improving the receiving stability, so that the upper die 2 always remains in the correct position during the flipping process, laying a good foundation for the subsequent clamping operation. At the same time, multiple receiving plates 10 form multiple groups of receiving spaces 11, and the multiple groups of receiving spaces 11 are centrosymmetrically arranged, which can ensure the smooth progress of the next receiving while flipping the upper die 2, improving the continuity of flipping.

[0039] As a further technical solution, it further includes: a protective shell 12 is arranged on the frame body 3, and a protective space 13 is provided inside the protective shell 12, and the flipping frame 4 is located in the protective space 13.

[0040] In this embodiment, the protective shell 12 wraps the flipping frame 4 within the protective space 13, which can effectively prevent the operator from accidentally coming into contact with the high-speed rotating flipping frame 4 during the working process, greatly reducing the risk of injury. When an accident occurs during the flipping of the mold, such as parts loosening and falling off, the protective shell 12 can play a blocking role to avoid harm to the surrounding personnel and equipment. The protective shell 12 can absorb and block the noise generated during the operation of the flipping frame 4 to a certain extent, creating a relatively quiet condition for the working environment and reducing the adverse impact of the noise on the operator. After installing the protective shell 12, the entire mold flipping and clamping device looks cleaner and more standardized, enhancing the appearance image of the equipment.

[0041] As a further technical solution, the flipping frame 4 is provided with a guiding groove 14, and further includes: a plurality of runners 15 are rotatably arranged within the protective space 13, and all the plurality of runners 15 are in contact with the guiding groove 14.

[0042] In this embodiment, the plurality of runners 15 are in contact with the guiding groove 14 on the flipping frame 4. When the flipping frame 4 rotates, the runners 15 can provide uniform supporting force and guiding effect for the flipping frame 4, making the flipping process smoother, reducing shaking and vibration, and ensuring the position accuracy of the mold during the flipping process. The assisted rotation of the runners 15 can share the load of the gear 9 transmission, reduce the wear of the gear 9, and extend the service life of the gear 9, thereby improving the stability and reliability of the entire device. Different specifications of molds may generate different pressures and torques on the flipping frame 4 during the flipping process. The runners 15 can be used as a further technical solution on the carrier vehicle 18, and the carrier vehicle 18 slides along the first guide rail 17.

[0043] In this embodiment, the support blocks 16 are arranged on both sides of the frame body 3, providing a stable support foundation for the carrier vehicle 18. The existence of the first guide rail 17 ensures that the carrier vehicle 18 travels smoothly along the established track during the conveying process, avoiding shaking and deviation, and ensuring that the upper mold 2 can be safely and accurately conveyed to the position of the flipping frame 4 for flipping and clamping operations. The carrier vehicle 18 slides along the first guide rail 17, and its movement mode is simple and intuitive. The operator can easily control the running speed and position of the carrier vehicle 18, improving the work efficiency. This design method of the conveying member 1 can make full use of the space on both sides of the frame body 3 without occupying too much working area, enabling the entire mold flipping and clamping device to operate more efficiently within a limited space.

[0044] As a further technical solution, it further includes: a second guide rail 19 is arranged on the frame body 3 in a lifting manner. After the second guide rail 19 is lifted, it approaches or moves away from the first guide rail 17.

[0045] In this embodiment, when the carrier vehicle 18 is in operation, the second guide rail 19 is at the same height as the first guide rail 17 and there is no gap. Therefore, the carrier vehicle 18 can move smoothly without jolting or other situations. When the carrier vehicle 18 transports the upper mold 2 to the turning frame 4 and fixes it, the second guide rail 19 will descend, separating the carrier vehicle 18 from the second guide rail 19. At this time, the carrier vehicle 18 continues to move, thus leaving the position of the turning frame 4, preventing collision with the carrier vehicle 18 during the turning process of the turning frame 4, and improving the completion degree of the upper mold 2.

[0046] As a further technical solution, the second guide rail 19 is a telescopic rod. After the second guide rail 19 is telescoped, it approaches or moves away from the first guide rail 17.

[0047] In this embodiment, the design of the telescopic rod enables the second guide rail 19 to not interfere with the turning frame 4 at all during the turning process of the turning frame 4, ensuring the continuity and stability of the turning process. The telescopic rod can provide stable support in the extended state. Compared with other movable guide rail structures, the telescopic rod has better rigidity and can withstand greater weight and impact force, ensuring the stability of the upper mold 2 during the transfer process.

[0048] As a further technical solution, it further includes: a limit block 20 is arranged on the frame body 3, and the limit block 20 is used to limit the position of the upper mold 2.

[0049] In this embodiment, the limit block 20 can accurately limit the position of the upper mold 2, ensuring that the upper mold 2 is always in the correct position during the conveying and turning processes, thereby guaranteeing the accuracy of mold closing. It avoids inaccurate mold closing caused by the position deviation of the upper mold 2 and improves the product quality. The limit block 20 can prevent the upper mold 2 from accidentally slipping or shifting during the conveying process, reducing the risk of injury to the operator. Especially during high-speed conveying or turning processes, the role of the limit block 20 is more important. The limit block 20 can prevent the upper mold 2 from accidentally slipping or shifting during the conveying process, reducing the risk of injury to the operator. Especially during high-speed conveying or turning processes, the role of the limit block 20 is more important. By adjusting the position and size of the limit block 20, it can adapt to upper molds 2 of different specifications and shapes, improving the versatility of the device. No matter how the size of the upper mold 2 changes, effective position limitation can be achieved through the limit block 20.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
