[0018] like Figure 1As shown, a mold changing device for a sheet metal production line includes a mold frame 1 and a transfer frame 2. The bottom of the transfer frame 2 is provided with multiple rollers 3 for moving the transfer frame 2. The bottom of the mold frame 1 is provided with multiple adjustable bases 4, four in total symmetrically distributed on the left and right sides of the mold frame 1. Two adjustable bases 4 on each side are respectively located at the front and rear ends of the mold frame 1. Since the ground is not flat, the mold frame 1 can be leveled by adjusting the adjustable bases 4. Each adjustable base 4 is provided with a slider 5, and below the slider 5 is a linear guide rail 6 adapted to the slider 5. There are two linear guide rails 6, each with two sliders 5. The linear guide rails 6 are arranged longitudinally to achieve the purpose of moving the mold frame 1 longitudinally, i.e., in the front-to-back direction. The transfer frame 2 is located on one side of the mold frame 1, and the transfer frame 2 and the mold frame 1 are arranged laterally, i.e., left-to-right. The mold 7 is located on the top of the transfer frame 2, and under the action of external force, the mold 7 moves between the top of the transfer frame 2 and the top of the mold frame 1. The centerline of the frame coincides with the centerline of the linear guide rail 6. The frame and mold holder 1 are arranged longitudinally. When mold 7 needs to be disassembled, first remove the bolts connecting mold 7 to the frame. Push mold 7 outward along the linear guide rail 6 using mold holder 1, ensuring mold 7 is away from the frame to allow for lateral movement and facilitate technician operation. Then, connect transfer frame 2 to mold holder 1. Technicians apply force to move mold 7 from mold holder 1 to transfer frame 2, and finally, transport and store mold 7 using transfer frame 2. When mold 7 needs to be installed, first transport mold 7 to the workstation using transfer frame 2, and adjust the position of mold holder 1 to facilitate longitudinal installation. Then, connect transfer frame 2 to mold holder 1. Technicians apply force to move mold 7 from transfer frame 2 to mold holder 1, and finally, connect mold 7 to the frame using bolts, thus completing the installation of mold 7.
[0019] like Figure 2 and Figure 3As shown, the mold frame 1 and the transfer frame 2 are respectively provided with moving tracks 11. The moving track 11 has a triangular cross-section. The bottom of the mold 7 is provided with track wheels 12, which are adapted to the moving track 11. The mold frame 1 is provided with a first connecting hole 13, and the transfer frame 2 is provided with a second connecting hole 14. The transfer frame 2 includes a connecting plate 15, which is located on the side near the mold frame 1. The second connecting hole 14 is located on the connecting plate 15. Bolts pass through the first connecting hole 13 and the second connecting hole 14 in sequence, and the mold frame 1 and the transfer frame 2 are fixedly connected. After the mold frame 1 and the transfer frame 2 are bolted together, the mold 7 will move along the moving track 11 under the action of external force. The moving track 11 on the mold frame 1 and the moving track 11 on the transfer frame 2 are connected, which facilitates the movement of the mold 7 on the moving track 11 of the mold frame 1 and the moving track 11 of the transfer frame 2. The mold frame 1 includes a support frame and a top plate. A movable track 11 is mounted on the top plate, which has a rectangular cross-section. The movable track 11 is positioned along the long side of the top plate, and its length is greater than the length of the long side of the top plate. The transfer frame 2 includes a top frame and a bottom frame. The top frame has a rectangular cross-section, and the movable track 11 is positioned along the long side of the top frame. The top frame and bottom frame are connected by a support beam. The movable track 11 is mounted on the top frame, and its length is less than the length of the top frame. When the movable track 11 on the mold frame 1 and the movable track 11 on the transfer frame 2 are connected, the connecting surface of the movable track 11 on the mold frame 1 and the movable track 11 on the transfer frame 2 is on the transfer frame 2, providing support for the movable track 11 and making the mold 7 more stable when moving on the movable track 11.
[0020] The first connecting hole is located on the top plate, specifically on the side of the top plate closest to the transfer frame. When a fixed connection between the mold frame and the transfer frame is required, the transfer frame 2 is positioned close to the mold frame 1, and the connecting plate 15 connected to the transfer frame 2 is located below the top plate. Technicians install fixing pins from above, allowing the pins to pass sequentially through the top plate and the connecting plate 15, thus achieving a fixed connection between the transfer frame 2 and the mold frame 1. This operation is simple. After the first connecting hole 13 and the second connecting hole 14 are aligned vertically, technicians install fixing pins to ensure that the moving track 11 on the transfer frame 2 is parallel to the moving track 11 on the mold frame 1, improving the smoothness of mold movement.
[0021] The adjusting base 4 includes a base 21, anchor nuts 22, and anchor bolts 23. The adjusting base 4 is distributed on both sides of the mold frame 1. Each adjusting base 4 is fixedly provided with an anchor nut 22, and the anchor bolt 23 is threaded into the anchor nut 22 with the head of the anchor bolt 23 facing upward. When the ground is uneven, the technician uses a tool to rotate the anchor bolt 23 to adjust the height of the corresponding part of the mold frame 1, so that the mold frame 1 is finally level.
[0022] A limiting block 24 is provided on the moving track 11 of the transfer frame 2. The limiting block 24 is located above the moving track 11 of the transfer frame 2 and is located on the side away from the mold frame 1. The limiting block 24 can stop the track wheel 12 from moving and prevent the mold 7 from falling off the transfer frame 2 due to inertia when it moves from the mold frame 1 to the transfer frame 2.
[0023] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
