Abstract:
A casting mold making apparatus and a method employing a tank with a pour hole formed at a bottom wall of the tank and an opening section open toward the opposite side to a bottom wall side. A first process of the method includes stirring component materials inside the tank with a stirring impeller so as to make a foam mixture while an opening section side of the tank is closed and the pour hole is closed. The second process is performed after the first process and includes opening the pour hole, pressing the tank against a mold such that a fill hole formed so as to pass into the mold is disposed adjacent to the pour hole, and supplying compressed air into the tank while stirring the foam mixture inside the tank with the stirring impeller so as to fill the foam mixture into a cavity of the mold.
