Abstract

The intention is to prevent the thin flat ejector (20) in the flat-ejector unit from being bent or buckled. For this purpose, it is guided over its entire length between two supporting surfaces in a guiding device (21). The guiding device (21) comprises two halves (21a) of a bolt-like element which is secured at one end, by a head (22), in a die half (12) and is supported radially at the other end in a bush (24) of an actuating unit (18). The mutually facing flat surfaces of the halves (21a) form the supporting surfaces. At the actuating end, the ejector has projections (20b) on which the actuating unit (18) engages in order to impart a lifting movement to the ejector (20). <IMAGE>
