Rotary type injection molding machine

A rotary injection molding machine, comprising:

• first and second oppositely located tables and a machine bed on which the tables are fixedly supported;
• a turntable supported on and extending generally parallel to the first table, and means for rotating the turntable;
• a clamping device and a releasing device for removing a molded article, the clamping and releasing devices being located on the second table on a side thereof which faces the first table;
• a plurality of cores mounted on the turntable on a side thereof which faces the second table, the turntable being selectively rotatable so that any one of the cores may be positioned in line with a selected one of the clamping device and the releasing device;
• means for moving the clamping device towards and away from the first table, the clamping device having a mold piece thereon for defining a mold cavity between the mold piece and one of the cores when the clamping device is positioned toward the first table;
• a molding station for carrying out injection molding operations located on that side of the first table which faces away from the second table and a runner plate disposed between the molding station and the first table;
• passage means formed in the cores for defining a passageway into the mold cavity;
• and
• means for selectively moving the molding station and the runner plate to first and second positions located, respectively, toward and away from the turntable, in the first position the runner plate defining a runner passage between itself and the core which runner passage communicates with the passage means for enabling injection of resin from the molding station through the runner and into the mold cavity, in the second position the runner and molding station enabling the turntable to rotate whereby the molded article formed in the mold cavity may be moved to the releasing device to be released from the core on which said molded article is located.
