| 摘要 |
<p>This invention relates to a rotary molding machine for molding a preform and hollow molded articles having a construction wherein a round transfer disc (10) having lip molds (18) at four sides of the lower side surface is supported rotatably at the center by a rotary shaft above a machine bed (1), and the stop positions of the lip molds (18) are used respectively as an injection molding operation part, a temperature controlling part, a stretch-blow molding operation part and a molded article withdrawing part to dispose molds (15, 16) and other devices. The rotary shaft of the transfer disc (10) consists of a piston (8) of an elevation cylinder (5) and this piston (8) and a driving shaft (7) of a driving device (6) for intermittent rotation are connected in a free state with respect to an axial direction so that the piston (8) can move up and down or intermittently rotate the transfer disc (10) with respect to each mold (15, 16).</p> |
