Molten metal supplying system for casting apparatus

摘要: PROBLEM TO BE SOLVED: To prevent the entrapment of gas causing a defective casting and to enable at low temp., pressure speed. SOLUTION: In molten metal supplying system, an injection tip 24 slidable in sleeve 22, auxiliary 27 formed movable die 21 over cylinder 25 matching 22 control means for drive-controlling 27, are provided. A vacuum space is between by separating both tips from position closely attaching tips, 31 furnace 30 sucked through stoke 32, poured into cavity 28.
