Then, control the rotary cylinder 47 to move downward through the rocker touch operation screen 5 to clamp and fix the die-casting mold 8. Then start the second variable-frequency motor 346 through the rocker touch operation screen 5. The second variable-frequency motor 346 drives the spindle head 342 to rotate through the rigid spindle 341. The rotation of the spindle head 342 drives the saw blade 343 to rotate at high speed. Finally, control the first variable-frequency motor 37 through the rocker touch operation screen 5. The first variable-frequency motor 37 drives the second lead screw 35 to rotate. The second lead screw 35 drives the second rod sleeve 36 to move. The second rod sleeve 36 drives the mounting table 33 to move, so that the saw blade 343 can move back and forth along the second linear guide 32 towards or away from the die-casting mold 8 to realize the rapid cutting of the blank on the die-casting mold 8.
