[0018] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0019] like Figures 1 to 3 As shown, this embodiment provides a flip mechanism for clamping a sub-frame, including: a fixed bracket 3, a clamping platform 1 and a motor 31, the clamping platform 1 and the motor 31 are fixedly arranged on the fixed bracket 3, and a flip plate 2 is arranged below the clamping platform 1, as shown in FIG. Figure 3 As shown, a fixed plate 17 is provided on the flip plate 2, and a rotating shaft driven by a fixed plate motor is provided at the center of the fixed plate 17, one end of the rotating shaft is rotatably connected to the bottom center of the clamping platform 1, and the other end is drivingly connected to the output end of the fixed plate motor 17, and one end of the flip plate 2 is rotatably connected to the first main shaft 311 of the motor 31, and the rotation direction of the rotating shaft is perpendicular to the rotation direction of the first main shaft 311.

[0020] The fixed plate motor is fixedly set on the flip plate 2, and a mounting block is set on the top surface of the fixed plate 17. The bottom of the clamping platform is snap-connected with the fixed plate 17 through the mounting block, so that when using the flip device, it is convenient to replace the clamping platform 1 of different sizes according to the sub-frames of different sizes.

[0021] like Figure 1 and Figure 2 As shown, in the above embodiment, the clamping platform 1 includes: a tooling panel 11 and a pressure claw 12, a support seat 13, a guide rod 14, a positioning column 15 and a detection base 16 fixedly arranged on the tooling panel 11 from the outside to the inside, wherein the pressure claw 12 is fixed with the support seat 13 after closing; the bottom of the pressure claw 12 is fixedly connected to a cylinder pad, and the pressure claw 12 includes an inner pressure claw 121 and a corner cylinder pressure claw 122, the inner pressure claw 121 is symmetrically arranged on the tooling panel 11, and the working direction of the pressure claw 12 is perpendicular to the tooling panel 11, and the corner cylinder pressure claw 122 is arranged on one side of the tooling panel 11, and the working direction of the pressure claw 12 is parallel to the tooling panel 11.

[0022] The support seat 13 is used to support the sub-frame on the tooling panel 11 during the cutting work. The guide rod 14 is used to ensure the stability of the sub-frame during rotation when cutting and displacing different runners and risers during the cutting work, so that it does not tilt during the position change process. The positioning column 15 and the detection base 16 are used to confirm the position of the sub-frame and determine whether the sub-frame is offset when it is fixed on the working panel for displacement.

[0023] The two ends of the flip plate 2 are respectively fixed with connecting plates 21 that are parallel to each other and perpendicular to the flip plate 2. The connecting plate 21 arranged at one end of the flip plate 2 is rotatably connected to the first main shaft 311, and the connecting plate 21 arranged at the other end is rotatably connected to the passive rotating member 32. The rotation direction of the passive rotating member 32 is consistent with the rotation direction of the first main shaft. The first main shaft 311 on the motor 31 drives the flip plate and the clamping platform to rotate around the axis.

[0024] The flipping mechanism is achieved by providing a rotatably connected rotating shaft on the flipping plate which is arranged parallel to the clamping platform and the bottom thereof, so that the flipping mechanism can rotate in the horizontal plane. In addition, the side surface of the flipping plate is rotatably connected to the first main shaft of the motor, so that the flipping plate can rotate around the main shaft of the motor in the vertical plane. Since the flipping plate and the clamping platform are connected by the rotating shaft and the two only rotate in the horizontal direction, the clamping platform can also rotate in the vertical plane. Therefore, after the sub-frame is clamped by the clamping platform, the sub-frame can be continuously displaced by the flipping mechanism, which makes it convenient for the master to cut off the redundant runners and risers on the sub-frame, significantly reducing the difficulty of operation, making the entire operation convenient and simple, and greatly increasing work efficiency.

[0025] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described herein, or equivalent structural or equivalent process transformations made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the scope of patent protection of the utility model.
