Inventor: SAKAI TAKAYUKI
IPC: B29C45/73
Filed: 2000-03-02
Abstract: PROBLEM TO BE SOLVED: To prevent the defective casting by easily holding the suitable temperature, even when the metallic mold grows cold by suspension of a casting line. SOLUTION: In a casting apparatus A constituted of the metallic molds of a lower mold 1 and a pair of side molds 2, fluidized bed furnaces 3 are integrally arranged at the back surface sides of the side molds. In these fluidized bed furnaces, fluidized beds 4 composed of powdery and granular materials of alumina, silica, zirconia or mixed materials thereof, are filled.
