Abstract

PURPOSE: To simply cut to separate a sprue at necessary portion by installing a floatable small refractory sphere within a cylindrical air gap chamber provided at the sprue to thereby shut off molten metal upon floating of the small sphere after completion of filling molten metal without disturbing the introduction of molten metal into a mold.
CONSTITUTION: Cylindrical air gap chambers 3, 5 are provided at desired position of the runner 2 of a mold, and a sphere 4 of floatable small refractory material is provided in the air gap chambers. When molten metal is poured from a sprue 1, it is sequentially filled through the runner 2 into a product 6 and a riser 7. When the molten metal fills all the air gap portion to complete the filling of molten metal, the sphere 4 floats in the air gap chambers 3, 5 to thereby block the upper sprue. The molten metal cooled to be solidified in this state and filled in the runner 2 is cut to be separated at the time of removing casting sand therefrom.
