Furthermore, a guide plate and a conveying structure / container can be set to convey or collect the workpiece.

[0043] The working principle of this utility model:

[0044] During use, the lower mold 2, in its active state, is located on the base 5. The lower mold 2 is stabilized by locking the corresponding movable frame 4 with locking element 6. One or two bolts can be added to further enhance the stability of the lower mold 2. The other movable frame 4 is unused and has no mold installed. When the product specifications change and the mold needs to be replaced, the replacement of the upper mold 1 can be done in the same way as before. When replacing the lower mold 2, first, fix the lower mold 2 to be used on an unused movable frame 4. Then, ensure the stamping equipment is stopped and the upper mold 1 is raised to a high position. At this time, release the locks on the lower mold 2 and movable frame 4. Rotate the movable frame 4 to flip the lower mold 2 out to the outside of the base 5. This flipping process can be assisted by an auxiliary rod 7 or a power source. Then, flip the other movable frame 4 to move the target mold onto the base 5 and lock it. Then, the subsequent stamping process can be performed. Afterwards, the lower mold 2 can be removed from the movable frame 4 after the movable frame 4 is relocked, so that the movable frame 4 can be used for the next replacement. The fixed frame 3 can also be replaced with a guide rail, the movable frame 4 slides with the guide rail, and a linear drive assembly is provided to drive the movable frame 4 to move, so that the mold can be pulled to the outside of the base 5 when it is necessary to replace the mold.

[0045] This application incorporates a movable frame 4 for connection with the lower mold 2. When the lower mold 2 needs replacement, it can be flipped to the outside via the movable frame 4, allowing for assembly and disassembly of the lower mold 2 from the outside of the base 5. The larger external space reduces operational difficulty. This solves the problem of limited space and high operational difficulty when replacing molds in existing technologies, and significantly reduces the risk of collisions with equipment during operation. Furthermore, since both the installation of the new mold and the removal of the old mold are performed on the outside of the base 5, this process can be synchronized with the stamping production process, greatly shortening downtime and improving production efficiency.
