[0024] In view of the shortcomings of the prior art, the inventor of this case, through long-term research and extensive practice, has come up with the technical solution of this utility model. The following will further explain the technical solution, its implementation process, and its principles.

[0025] like Figure 1 , Figure 4 As shown, this utility model discloses a pressing frame mold changing lifting mechanism, including a support frame 1 and a second driving mechanism 3. The interior of the support frame 1 is hollow, and the size of the hollow part inside the support frame 1 is larger than the size of the pressing frame, allowing the pressing frame to pass through the hollow part inside the support frame 1. Support positioning rods 13 are provided on the support frame 1, and the support positioning rods 13 are used to support at least the pressing frame. The number of support positioning rods 13 is set according to actual needs; four, six, eight, or more support positioning rods 13 can be provided. In this embodiment, four support positioning rods 13 are provided, and the four support positioning rods 13 are symmetrically arranged on the two crossbeams of the support frame 1. Each of the support positioning rods 13 is provided with a first driving mechanism 2 on one side. The first driving mechanism 2 is at least used to drive the support positioning rod 13 to extend or retract, so that the support block extends to support the pressure frame, or to retract the support block. The first driving mechanism 2 may include a cylinder or a motor and a lead screw. In this embodiment, the first driving mechanism 2 includes a cylinder. The driving end of the cylinder is fixedly mounted on the support frame 1, and the driving end of the cylinder is fixedly connected to the support positioning rod 13.

[0026] The second driving mechanism 3 is disposed on one side of the support frame 1. The second driving mechanism 3 is at least used to drive the support frame 1 to move up and down. The second driving mechanism 3 may include a cylinder, a motor, and a lead screw. In this embodiment, the second driving mechanism 3 includes a cylinder, and the driving end of the cylinder is fixedly connected to the support frame 1. Specifically, to prevent the second driving mechanism 3 from jamming during the upward or downward movement of the support frame 1, the driving end of the second driving mechanism 3 is hinged to the support frame 1 via a connecting piece. More specifically, as... Figure 2As shown, the driving end of the second driving mechanism 3 is connected to a fisheye connector 4, and a connecting seat 5 is provided on the support frame 1. The fisheye connector 4 and the connecting seat 5 are connected by a movable bearing 6.

[0027] When the pressure frame needs to be lifted, the first drive mechanism 2 drives the support positioning rod 13 to extend, the support positioning rod 13 supports the pressure frame, and the second drive mechanism 3 drives the support frame 1 and the support positioning rod 13 to move upward, thereby driving the pressure frame to move upward to disengage from the pressed product.

[0028] In this application, the support positioning rod 13 is connected to the support frame 1 and contacts the pressure frame under the drive of the first drive mechanism 2. Compared with the existing pressure frame which is fixed to the support frame 1, this application can be applied to different pressure frames, has strong applicability, avoids each pressure frame corresponding to a separate device, and reduces equipment costs. This application enables quick replacement of the pressure frame through the first drive mechanism 2 and the second drive mechanism 3.

[0029] In some implementation cases, such as Figure 3 As shown, to improve the accuracy of the second drive mechanism 3 in driving the pressure frame to move up and down, a guide shaft 7 is provided on one side of the second drive mechanism 3. One end of the guide shaft 7 is fixedly connected to the support frame 1, and the other end of the guide shaft 7 is provided with a thrust bearing 8. The guide shaft 7 is disposed inside the thrust bearing 8, and the guide shaft 7 moves relative to the thrust bearing 8 in the driving direction of the second drive mechanism 3. During the process of the second drive mechanism 3 driving the support frame 1 to move up and down, the guide shaft 7 moves up and down relative to the thrust bearing 8, thereby improving the accuracy of the up and down movement of the support frame 1.

[0030] Based on the above, to prevent the support frame 1 from suddenly falling due to a sudden gas cut-off or leakage in the cylinder, a limiting mechanism 9 is provided below the guide shaft 7. The limiting mechanism 9 is at least used to limit the position of the guide shaft 7 to prevent it from falling during the process of the second drive mechanism 3 lifting the support frame 1. Specifically, the limiting mechanism 9 includes a limiting rod 10, and a third drive assembly 11 is provided on one side of the limiting rod 10. The third drive assembly 11 is at least used to drive the limiting rod 10 to extend or retract, so that when the limiting rod 10 extends, it blocks the bottom of the guide shaft 7, and when the limiting rod 10 retracts, it avoids the guide shaft 7. The third drive assembly 11 may include a cylinder or a motor and a lead screw. In this embodiment, the third drive assembly 11 includes a cylinder, the limiting rod 10 is located below the guide shaft 7, and one end of the limiting rod 10 is fixedly connected to the drive end of the cylinder. When the second drive mechanism 3 drives the support frame 1 to move upward to the top, the lowest end of the guide shaft 7 is higher than the height of the limit rod 10. When the third drive assembly 11 extends the limit rod 10, the limit rod 10 is located below the guide shaft 7 and supports the guide shaft 7, which can prevent the guide shaft 7 from falling downward, that is, it can prevent the support frame 1 from falling when the cylinder suddenly stops or leaks air.

[0031] Based on the above, in order to make the upward or downward movement of the drive frame smoother, multiple sets of the second drive mechanism 3, guide shaft 7, thrust bearing 8, and limiting mechanism 9 are symmetrically arranged along the center of the support frame 1. The second drive mechanism 3, guide shaft 7, movable bearing 6, and limiting mechanism 9 can be arranged in four, six, eight, or more sets; in this embodiment, four sets of each are provided. More specifically, a fixed seat 12 is provided on one side of the second drive mechanism 3, and the fixed ends of the second drive mechanism 3, thrust bearing 8, and third drive assembly 11 are all fixedly mounted on the fixed seat 12.

[0032] It should be understood that the above embodiments are merely illustrative of the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
