[0026] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when in use, when the mold head needs to be disassembled and replaced, the rotating plate 3 can be rotated, and the rotating plate 3 rotates to drive the worm 908 to rotate. The worm 908 rotates through the worm gear 907 to drive the rotating rod 906 to rotate. The rotating rod 906 rotates to drive the bidirectional screw 903 to rotate. The bidirectional screw 903 rotates to drive the two moving blocks 901 to move in a direction away from each other. The movement of the two moving blocks 901 drives the fixed rod 904 to move in a direction away from the fixed groove 905 until the fixed rod 904 is disengaged from the fixed groove 905, and then the mold head body 14 is moved downward until the mounting block 13 is disengaged from the mounting groove 12, thereby completing the disassembly of the mold head. When a new mold is needed, When installing the mold head, place the mold head directly below the lifting plate 2, and align the mounting block 13 with the mounting groove 12, then move the mold head upward until the mounting block 13 is inserted into the mounting groove 12, then rotate the rotating plate 3 in the opposite direction, and finally drive the fixing rod 904 to be inserted into the fixing groove 905, thereby completing the fixation of the mounting block 13, and then completing the installation of the mold head. This solves the problem that when the mold head needs to be disassembled and replaced, it is necessary to rotate multiple threaded rods to complete the disassembly of the mold head. Similarly, when a new mold head is installed, it is necessary to install multiple threaded rods again, which is inconvenient. Moreover, after multiple disassembly and assembly, it is very easy to cause the threaded rods to loosen, seriously affecting the use effect of the mold head.

By facilitating the effective fixation of the workpiece to be stamped, the stamping effect can be improved.

[0029] Working principle: In the present application, when the mold head needs to be disassembled and replaced, the rotating plate 3 can be rotated, and the rotating plate 3 drives the worm 908 to rotate, and the worm 908 drives the rotating rod 906 to rotate through the worm gear 907, and the rotating rod 906 drives the bidirectional screw 903 to rotate, and the bidirectional screw 903 drives the two moving blocks 901 to move in the direction away from each other, and the two moving blocks 901 move and drive the fixed rod 904 to move in the direction away from the fixed groove 905 until the fixed rod 904 is disengaged from the fixed groove 905, and then the mold head body 14 is moved downward until the mounting block 13 is disengaged from the mounting groove 12, thereby completing the disassembly of the mold head. When installing a new die head, place the die head directly below the lifting plate 2, and align the mounting block 13 with the mounting groove 12, then move the die head upward until the mounting block 13 is inserted into the mounting groove 12, then rotate the turn plate 3 in the opposite direction, and finally drive the fixing rod 904 to be inserted into the fixing groove 905, thereby completing the fixation of the mounting block 13, and then completing the installation of the die head. Secondly, when the workpiece to be stamped is placed in the placement groove 6, the two limit screws 4 can be rotated to make the two limit blocks 10 move in a direction approaching each other until they contact the workpiece to be stamped and effectively fix it.
