ABSTRACT:
In a plunger for a cold chamber casting machine a mouth piece is positioned and held by only three small holding elements equally spaced in peripheral direction and fastened at plunger components. A cooling liquid pipe extends into the plunger. Between the front wall and the back wall of the plunger and the mouth piece, endside flow chambers are formed respectively communicating with the annular flow chamber formed between the plunger casing and the mouth piece along the whole circumference. Therefore the inside faces of the plunger end walls are completely accessible to cooling liquid and the plunger end walls are effectively cooled.
