Abstract: The invention relates to a die casting ring (1) internally fitted with radial teeth (11) to be engaged into matching seats (22) provided on a piston (2). This piston-ring assembly prevents mutual rotation or axial translation, in addition to ensuring an optimal seal against infiltration of liquid metal during the die casting process. When the ring has a cutout (10), it can be mounted accurately onto the piston because the teeth (11) allow the cutout to be positioned anywhere relative to the piston.
Abstract: A pressure die casting piston assembly has a pressure die casting piston. The die casting piston has a front head, a substantially cylindrical side wall extending upwardly from the front head in fixed position relative thereto. A cup-shaped chamber is defined by the front head and the side wall. The side wall is closed by the front head. The die casting piston has a coolant channel passing through the side wall to allow a coolant to pass through the side wall and within the side wall.

Abstract: The invention relates to a die casting piston (20) and a respective support (2). The piston has a wall (21) in which channels for a coolant flow are obtained: this improves the thermal exchange between the piston and the coolant, leading to greater cooling efficiency.
