APPARATUS FOR MOLDING INORGANIC HYDRAULIC MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To efficiently perform releasing from the molding face of a mold with a releasing agent and to improve suction properties of a molded article to a top mold by pushing up the molded article consisting of an inorg. hydraulic material such as e.g. cement mortar, clay, ceramic and gypsum by means of a rod valve and forming a gap allowing entry of air between it and the molding face in relation to an apparatus for an inorg. hydraulic molded article. SOLUTION: Through-hole parts 4 for performing water squeezing and air suction of a molded article N are provided on the molding face S1 of one of molds consisting of a top mold 1 and a bottom mold 2 and a valve hole 5 is provided on the molding face S2 of another mold and a rod valve 7 is inserted and arranged in a valve passage 6 at the height where the apex part 7a closes the valve hole and a driving mechanism part 9 which makes the rod valve forcibly project is provided movably up and down.
