CASTING MOLD MAKING APPARATUS AND MOLD MAKING METHOD
20210276076 · 2021-09-09 ·

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.

MOLDING METHOD
20210291258 · 2021-09-23 · ·

A cycle is repeatedly carried out, the cycle including: a material feeding step of feeding a material whose amount is larger than an amount that is needed to form a single mold; a mixing step; an ejection step; and a measurement step of measuring, once before or after the ejection step, an amount of foamed mixed sand contained in a mixing tank. The material at least partially is not fed in the material feeding step in the cycle in which the amount of the foamed mixed sand is not less than a first threshold.
