摘要： PROBLEM TO BE SOLVED: To realize a casting equipment with which a high quality cast product having a uniform strength over the entirety is formed by solidifying at a uniform speed the whole molten metal cast in a mold while keeping a balance between radiant heat discharged from a mold on the inner space side surrounded by a number of molds and the radient heat discharged from a mold on the outer space side.
SOLUTION: Eight runners 63a-h communicating with each other are provided on one gate 61. Eight casting molds 64a-h each communicating with the runners 63a-h respectively are fixed on a water cooled plate 21 with a circular cavity in the center so as to form a cylinder. The water cooled plate 21 is held by a cylindrical and vertically movable elevation shaft 22 having a cavity with the same diameter as that of the cavity of the water cooled plate 21. Then, a cooling pipe 11 is arranged which is inserted through each cavity of the water cooled plate 21 and the elevation shaft 22 and which is designed to circulate cooling water inside.
