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