Abstract (en)
[origin: US2009139683A1] A multi-piece piston (1) is disclosed, for fixing to the high pressure side end (3) of a piston rod (5) running axially in a casting cylinder (7) of a cold chamber casting machine. The piston comprises a piston crown (9) forming a piston front face (13) on the high pressure side and a piston body (15) in the form of a bush connected to the piston crown (9) on the low pressure side. The piston body (15) can be connected to the piston crown (9) by means of fixing screws (23) to form a module. Complementary bayonet locking means (25, 27) are provided, for axial fixing of the piston (1) to the end (3) of the piston rod (5), on the piston crown (9) and the end (3).
