) is filled with a low melting point alloy material from a hot water supply port (4) via a runner (5), the first casting mold (1) and the second casting mold (2) A plug member (7) having a through hole (6) opened to the runner (5) formed in at least one side thereof and having a heating member (9) and a cooling member (10) built in the through hole (6). A casting mold characterized in that the runner (5) is movably arranged, and the runner (5) can be closed by movement of the plug member (7). (2) The plug member (7) has a main body (
8), a heating member (9) consisting of a heater embedded in this main body (8), and a cooling member (10) consisting of a cooling pipe.
) The casting mold according to claim 1, comprising: (3) A heating member incorporating the plug member (7) according to claim 1 (
9), and while holding the runner (5) in the open position, fill the casting cavity (3) with the low melting point alloy material from the hot water supply port (4) via the runner (5). After filling is completed, the cooling of the low melting point alloy material in the casting cavity (3) begins, and the plug member (7) is moved to a position where it closes the runner (5), and the built-in cooling member ( 10) A casting method characterized by cooling.
