[0002] In the automotive manufacturing industry, in order to maintain the integrity and sturdiness of the vehicle body shell, metal materials are mostly used to make parts and shells. Either hot-melt metal is poured into a mold for shaping, or stamping dies are used to press and shape the metal sheet in one go. If there are any unsatisfactory parts, shaping dies can be used to reshape it.
[0003] Most of these forming molds have detailed upper and lower molds. The cylinders are used to adjust the opening and closing of the two molds to perform fine processing on the sheet metal after pressing and shaping. However, the metal sheet metal that has been pressed multiple times is often stuck together with the lower mold and cannot be easily removed, making it difficult to improve the efficiency of the forming process.

If the upper mold 21 continues to press down, the pressure plates 17 attached to both sides of the upper mold 21 will contact the top of the pad 32 and continue to press the pad 32 with the spring 8 on the lower slide bar 7 along the movable groove 2. Then, the edges on both sides of the metal sheet are shaped. The balance bar 16 can be held and raised and lowered in front of the housing 12, and the pressure plate 17 moves along the slot 19 together. After aligning with the screw hole 18, the bolt 2 31 is screwed in to fix it.
[0020] A reinforcing block 30 is fixed to the upper right corner of the base 1, and a motor 9 is fixed to the bottom of the reinforcing block 30. A rotating rod 10 is movably connected to the top of the reinforcing block 30, and a sleeve block 27 is sleeved on the outside of the top of the rotating rod 10.

When the upper mold 21 and the lower mold 22 are pressing the metal sheet, the excess edges on both sides of the metal sheet adhere to the symmetrical pads 32. If the upper mold 21 continues to press down, the pressure plates 17 adhering to both sides of the upper mold 21 will contact the top of the pads 32, continuing to press the lower slide rail along the movable groove 2. The rod 7 has a pad 32 with spring 8, which then shapes the two sides of the metal plate. The balance bar 16 can be held and raised and lowered in front of the housing 12, moving along the slot 19 together with the pressure plate 17. After aligning with the screw hole 18, the second bolt 31 is screwed in to fix it. Finally, the crossbar 11 is fixed above the rotating rod 10 through the sleeve block 27. Then, the two sets of holes 29 are aligned and the first bolt 28 is screwed in to prevent the crossbar 11 from detaching from the rotating rod 10. After the shaping is completed, the housing 12 and the upper mold 21 are moved to adjust the distance between the upper mold 21 and the lower mold 22. The motor 9 is started and the rotating rod 10, the crossbar 11, the brush roller 26, etc. are rotated to clean the top of the lower mold 22 and the bottom of the upper mold 21.
