Because draw forming class mould is in forming process; Must to the mould blank holder pressure-pad-force (or nitrogen spring etc. provide) be provided through the press air cushion; But type mould draw forming time-like mould off-centre is installed seriously owing to unite; The eccentric load that the press air cushion receives is bigger, causes the pressing precision variation easily, quality risks such as product quality of production instability.The present invention turns in the whole type of mould at Xiu Chong increases haltere so that its patrix is supported, so just can the balance air cushion pressure.The more important thing is; Identical and the synchronization action of the stroke of air-cushion eject-rod and balance post rod; When the patrix that can guarantee draw forming class mould contacts with blank holder, repair and dash the patrix that turns over whole type of mould and also contact with haltere simultaneously, so just guaranteed the stress balance of press air cushion.
Further, said repairing towards flange class lower mould is provided with guide pin bushing, and haltere passes guide pin bushing and is slidingly matched with guide pin bushing, can lead to haltere through guide pin bushing, prevents the haltere run-off the straight.
Further, said repairing towards flange class mould is provided with the disconnecting prevention structure that prevents that balance post rod from coming off, to prevent that when balance post rod falls balance post rod comes off from repairing towards the counterdie of flange class mould, causes security incident.
Specifically, the top of said haltere is provided with the annular groove of diameter less than the excellent body diameter of haltere, and said annular groove length is greater than the stroke of balance post rod; Said disconnecting prevention structure is to be installed on to repair the flat board that dashes the counterdie end face turn over whole type of mould, and said flat board is provided with through hole, and the diameter of said through hole is less than the diameter of the excellent body of haltere and greater than the diameter of annular groove.When haltere fell along with balance post rod, the excellent body of the haltere of annular groove top will be stuck in dull and stereotyped through hole, guaranteed that haltere can not come off from repairing to dash the counterdie that turns over whole type of mould; And the length of annular groove must rise to after top dead center with convenient haltere along with balance post rod greater than the stroke of balance post rod, and the haltere of annular groove below can not interfered with the through hole of flat board yet.
Further, said flat board is installed in to repair and dashes on the counterdie end face turn over whole type of mould, falls behind down when balance post rod like this, and dull and stereotyped concordant spacing on the whole type of lower mould will be turned over repairing to dash in the top of haltere spill annular groove, can not influence the work of mould.
The method of balancing load is through the use of haltere in the die production of the present invention; Effectively solved the problem of press air cushion unbalance loading; Mould and equipment are played a very good protection, and the quality stability of the rolled-up stock that liquidates also plays a good role, and has good practicability.
