When the mold needs to be replaced, the second electromagnet 66 and the first electromagnet 63 are started, and the second electromagnet 66 and the first electromagnet 63 are magnetically held. At this time, the first electromagnet 63 pushes the solid column 62 to slide inside the empty sliding column 65, and the outer side of the solid column 62 fits with the inner side of the empty sliding column 65. The first gear ring 64 moves away from the second gear ring 67, and the solid column 62 drives the wide plate 61 to move. The wide plate 61 drives the steel ball 85 and the folding plate 84 to move, and the folding plate 84 drives the sliding column rod 82 to move. The sliding column rod 82 is slidably connected within the limit. The inner side of the block 81 plays a role in limiting the movement of the folding plate 84.

When the mold mounting frame 71 on the stamping and forming device body 1 rotates, the mold mounting frame 71 on the stamping assembly 3 rotates at the same time under the action of the magnetic attraction force. When the mold mounting frame 71 rotates, it drives the solid column 62 and the wide plate 61 to rotate. The outer side of the solid column 62 fits with the inner side of the air sliding column 65, which does not affect the rotation of the solid column 62. When the wide plate 61 rotates, the outer side of the steel ball 85 fits with one side of the wide plate 61, and the steel ball 85 rotates inside the folding plate 84, which can reduce the friction when the wide plate 61 rotates, reducing the labor during operation. Dynamic strength. When the mold body 76 to be used is aligned with the bayonet 4, the second electromagnet 66 and the first electromagnet 63 are powered off. At this time, under the elastic tension of the tension spring 83, the folding plate 84 and the steel ball 85 move, and the steel ball 85 pushes the wide plate 61 and the solid column 62 to move. When the first gear ring 64 is engaged with the second gear ring 67, the mold mounting frame 71 can be limited to improve the stability during stamping. The electric telescopic rod 73 drives the extrusion plate 75 to slide inside the rectangular slide groove 74, so that the mold body 76 can be disassembled and replaced, thereby improving the maintenance efficiency.
