When it is necessary to stamp the workpiece, the workpiece and the lower mold 3 need to be fixed. The servo motors 12 arranged inside the two groups of movable grooves 7 will drive the threaded column 14 to rotate through the rotating shaft 13. When the threaded column 14 rotates, it will perform threading action with the threaded hole 16 inside the moving block 15. The two groups of moving blocks 15 drive the fixed block 17 to move left and right through this threading action. When the mold clamping plates 19 arranged at one end of the two groups of fixed blocks 17 fix the lower mold 3 in the middle, the two groups of electric rods 20 will continue to push the two groups of workpiece clamping plates 21 to move, so that the two groups of workpiece clamping plates 21 fix and clamp the workpiece. When the workpiece is fixed and clamped, the hydraulic cylinder 4 arranged inside the operating frame 2 will push the upper mold 5 downward to stamp the workpiece.

When the workpiece clamping plates 21 need to be installed to fix workpieces of different shapes, the limiting grooves 26 provided inside the mounting blocks 25 are aligned with the limiting blocks 23 provided on the outer surface of one end of the connecting plates 22, so that the limiting grooves 26 and the limiting blocks 23 are interlocked with each other. At this time, the two groups of square holes 27 provided on the outer surface of the upper end of the limiting grooves 26 will be aligned with the two groups of interlocking holes 24 provided on the outer surface of the upper end of the limiting blocks 23, and then the two groups of interlocking columns 28 are passed through the two groups of square holes 27 and interlocked with the two groups of interlocking holes 24, so that the limiting blocks 23 and the mounting blocks 25 are fixedly installed, and at the same time, the workpiece clamping plates 21 are fixed to one end of the electric rod 20, so that workpieces 21 of different shapes can be installed to fix and clamp workpieces of different shapes.

[0025] It should be noted that the utility model is a metal stamping forming mold. When in use, the two sets of servo motors 12 can drive the two sets of threaded columns 14 to rotate, so that the two sets of moving blocks 15 drive the fixed blocks 17 to move left and right through the threaded action between the threaded columns 14 and the threaded holes 16. When the two sets of fixed blocks 17 move left and right, they will drive the two sets of mold clamps 19 to move left and right, so that the two sets of mold clamps 19 fix the lower mold 3. At the same time, the two sets of electric rods 20 can continue to push the two sets of workpiece clamps 21 to move, so as to fix and clamp the workpiece. The hydraulic cylinder 4 can push the upper mold 5 to move downward to stamp the fixed workpiece. The limit block 23 can be embedded with the limit groove 26 inside the mounting block 25.
