Abstract
A vertical die casting machine comprising: a casting cylinder, pivotably mounted to a base, for activating a piston extension slidably fitted in a casting sleeve, and; a hollow block having an upper end connected to the casting sleeve and having a bore reduced at a lower end thereof through which bore the piston extension extends into the block. The block is forced to move by a ram cylinder relative to the casting cylinder. The piston extension has a radial extension in the block designed so that an engagement of the radial extension with the reduced bore end of the block causes a positional relationship between the casting sleeve and the piston extension to be maintained constant during an axial downward movement of the piston extension driven by the casting cylinder and during an axial upward movement driven by the ram cylinder.
