Abstract

The invention relates to a method and a device for damping the pressure peak which occurs at the end of the die filling phase in die-casting machines, a hydraulic damping device, the hydraulic chamber of which is closed off by a spring-loaded control piston, being arranged between the piston rod of the plunger and the piston rod of the shot piston. <??>The method according to the invention is characterised essentially in that the inertia of the control piston (4) which comes into effect when the plunger (14) is braked, is used to open the damping chamber (9) of the damping device (16). <IMAGE>
