| 摘要 | PURPOSE:To produce easily a resin mold pattern having an optional size and shape by molding and curing a hollow negative mold, holding said mold in a rotary drum, pouring and curing a fluid resin into the hollow part of the negative resin to form the pattern. CONSTITUTION:A revolving shaft 2 is provided in the closed part of the rotary drum 1 and an annular barrier 3 is provided on the inside surface near the aperture. The drum 1 is rotated and a molding material 5 consisting of gypsum or the like is poured from a container 4 into the drum, then a hollow cylindrical drum 6 is molded by centrifugal force and is cured. The barrier 3 is removed and the inside surface of the body 6 is machined by a cutter 7 to form the negative mold 8 having the prescribed shape and size. The barrier 3 is again attached thereto and a molten resin 10a is poured from a container 9 into the negative mold 8 and is molded by cantifugal force. The mold is cooled and cured to form a cured resin body 10b. The resin body 10b is taken out together with the mold 8 and the mold 8 is removed, by which the resin mold pattern 11 for casting is obtd. | ||||||
