Abstract: A device and process for forming threaded molded articles includes first and second mold halves having mold surfaces which are adapted to form a molded plastic article. The first mold half cooperates with the second mold half to form a mold cavity in a mold closed position. A nozzle for injecting plastic material into the mold cavity and a power source for relatively moving the first mold half to a position spaced from the second mold half to form a mold open position, are provided. The device also includes a movable ejection mechanism for loosening the article from the mold surface of the second mold half and for ejecting the article from the mold surface of the second mold half while in the open position. A moving mechanism is connected with the movable ejection mechanism for transmitting power to and inducing motion of said ejection mechanism. An initial source is included which converts the relative motion of the mold halves into power for powering the transfer mechanism.
