Vacuum die casting machine having improved siphon tube and associated method

摘要

Vacuum die casting machine including an improved siphon tube for transporting molten metal from a reservoir to a shot cylinder. The siphon tube defines a passageway having a first end portion which is adapted to communicate with a shot cylinder and a second end portion opposite the first end portion which defines a molten metal entry portion. The passageway tapers from the first end portion to the second end portion which reduces jetting in the shot cylinder. An associated method is also disclosed.
