PURPOSE:To enable a plurality of support plates to function independently by making either an ejector pin or a control rod pierce through a support plate on the other side to extrude each support plate with a rod selectively to a fixed retainer plate. CONSTITUTION:A motor 22 is operated to rotate a rotary support plate 18 so that an ejector rod 11 will face a through hole 6a. As a cylinder 19 is driven to extend a cylinder rod 19a, the plate 18 and the ejector rod 11 rise and stick an ejector pin 12 out of a retainer plate 2 passing through the through hole 6a and an insertion hole 10a to separate a molding 14a and a sprue runner 14c from the retainer plate 2. Then, the ejector rod 11 is lowered and the motor 22 is operated again to rotate the plate 18 so that the ejector rod 11 faces a through hole 6b. As the cylinder 19 is operated, the ejector rod 11 rises and sticks an ejector pin 15 out of the top surface of a core 16 passing through the through hole 6b to separate a molding 14b from the retainer plate 2. |
