Described upper die component comprises upper bolster, upper padding plate and upper solid plate, described upper padding plate and upper solid plate are successively set on below upper bolster from top to bottom, described upper solid plate is provided with drift, upper plate two ends are admittedly to having bolt structure, this bolt structure runs through stripper plate two ends respectively, and connect lower mold assemblies, described stripper plate is provided with the bore of the punch moved up and down for drift, nitrogen spring is connected with between described stripper plate and upper bolster, compared to excellent power glue, nitrogen spring, de-material power is even, the not de-material of little generation, get stuck phenomenon.
Described lower mold assemblies comprises the die shoe, lower bolster and the lower bolster that stack setting from top to bottom successively, this lower bolster is provided with counterdie from top to bottom successively at the correspondence position of drift and enters block and counterdie cushion block, the two ends of described lower bolster are respectively equipped with the screw mouth matched with bolt structure, the height of block is entered by shortening counterdie, and counterdie cushion block is set below, the intensity making counterdie enter block greatly strengthens, and the counterdie occurred high pressure during workpiece punching because of mold notch enters block and stays phenomenon and greatly reduce.
The two ends correspondence position of described upper bolster and die shoe is respectively equipped with connecting hole, upper bolster and die shoe is coupled together by the connecting rod matched with this connecting hole.
Described lower bolster is provided with the locating hole of multiple auxiliary work-piece location.
Described locating hole is provided with four, and these four locating holes are arranged in square.
The material of described mold notch is SKH51, SKH51 is tungstenic high-speed tool steel, mold notch has high-wearing feature, high compressive strength, harden after high case hardness, excellent integral quenching permeability, good surface treatment processability and excellent anti-temper softening, good to the processing effect of workpiece, not easily produce burr and the phenomenon such as to weigh wounded, greatly reducing the generation that counterdie enters the edge of a knife fracture phenomenas such as block.
Compared with prior art, the present invention has the following advantages:
(1) save the operating time, enhance productivity: the present invention is by replacing excellent power glue by nitrogen spring, thus reduce the generation of not de-material, the phenomenon that gets stuck, enter block by shortening counterdie and counterdie cushion block is set below, increase counterdie and enter bulk strength, reduce and stay phenomenon, thus repairing a die old 2 ~ 3 hours every days of mould the time, be reduced to and often produce 2 ~ 3 talentes and repair 1 mould, substantially increase production efficiency;
(2) product quality is obviously improved: lower bolster is provided with locating hole, and auxiliary work-piece is located, thus effectively ensures the precision to workpiece punching, and ensure the punching requirement to workpiece, the Work-piece burr phenomenon after punching obviously reduces, and product weighs minimizing wounded;
(3) cost is low: mold repair expense of the present invention greatly reduces, and maintenance die master worker workload greatly reduces, and maintenance personal reduces to 4 by 5.
