Abstract

PURPOSE:To secure exact and simple exchange between direct and indirect press by attaching moveably diestem in the direction of press at the central position of press on rear end side of press platen. CONSTITUTION:The diestem is first slided, and then while its rear end is located at a place in front of the press platen 1, the stem 2 is exchanged with the die bolster 57 for direct pressing. On the other hand, the diestem guide 24 is located out of the press by the moving means 27 to exchange with the guide ring 25 for exchanging it with the die 58 and the die holder 59 for direct pressing. Afterwards, the assembly is situated by the moving means at the central part of press, the die bolster 57 is forwarded into the press platen 1, and the locking gate 8 is fitted in the groove 57a of the bolster 57. Thus, only by exchanging simple attachments, the indirect press can be easily and exactly converted into direct press.
