Abstract

PURPOSE:To prepare a molded article of a large height while reducing a stroke for opening a mold by a method wherein after a resin molded article is formed in all cavities by means of a polygon split type extrusion metallic mold, molds are sequentially opened and a molded article is taken out. CONSTITUTION:A polygon split type extrusion metallic mold is used which is provided with a mechanism to selectivel fix or open each metallic mold split face. While retaining a state wherein all split faces of a metallic mold are tightened for mold, a molten resin is poured into all cavity parts 15, 16 from a cylinder nozzle 19 which is made to contact with a central movable member and this resin is cooled and cured. Next thereto, a B-B split face is fixed and a A-A face is released to open a mold and then, a molded article 17 is released from a male mold 3 by means of a stripper plate 5. and then, the A-A face is made to contact and is fixed, and the B-B face is opened and a molded article 18 is released from a male mold 4 in the same way as before.
