Abstract (en)
The invention concerns equipment for removing the bobs (runners, gates)(16,17) from die-cast pieces (11). It is made up of hubs (18,19) mounted crossways in the parts or half dies (12a,12b) of the die, facing the bobs at the height of the attachment zones (16',17') of the latter to the piece. The hubs are moved to push away and detach the feedheads after the piece has been moulded and before the die is opened to lift off the said piece. <IMAGE>
