The bottom end of the outer wall of the locking component 6 contacts the T-shaped guide groove 11. Specifically, first, the base 1 is fixedly installed on the working surface of the stamping machine. The T-shaped guide grooves 11 are parallelly distributed and the spacing is set according to the die size. The positioning mechanism 2 is slid along the guide groove 11. Through the slider 21 being embedded in the groove, the sliding base 22 is moved to the set position. Then, rotate the four-corner adjusting handwheel 15 to drive the threaded adjusting rod 10 to lift the support column 12 until the hemispherical positioning head contacts the bottom surface of the mold. Subsequently, tighten the adjusting bolt 7 of the locking assembly 6 to press the friction gasket 8 against the inner wall of the T-shaped guide groove 11 to fix the position of the sliding base 13; Finally, place the mold between the clamping ends 18 of the elastic clamping arms 9.
