Abstract:
An automatic molten metal injector is provided which has no rotary frictional parts and is thus durable. The injector has a furnace (1) holding a molten metal to a predetermined level and having a first port (7). A fixed sleeve (8) is provided in the furnace so as to be submerged in the molten metal and having a second port (9) communicating with the first port. A slide sleeve (11) having a side wall formed with a third port (14) and a closed bottom wall is received in the fixed sleeve so as to be vertically slidable between a raised position in which the third port communicates with the second port (9), and a lowered position in which the third port communicates with the interior of the furnace. A piston (12) is vertically slidably received in the slide sleeve. A drive unit (13) individually or simultaneously raises and lowers the slide sleeve and the piston.
