Apparatus for forming threaded molded articles

A molding device for forming a molded article and ejecting the molded article therefrom, said device comprising:

• a first mold half having a mold surface for forming said molded plastic article;
• a second mold half having a mold surface cooperating with the mold surface of said first mold half to form a mold cavity therebetween in a mold closed position;
• means for injecting plastic material into said mold cavity;
• motive means for causing relative motion between said first mold half and said second mold half to space said first mold half from the molded article and said second mold half to form a mold open position;
• a movable ejection means for breaking said article loose from said mold surface of said second mold half and for ejecting said article from said mold surface of said second mold half while in said open position, said ejection means positioned adjacent said second mold half and adapted to be placed into contact with said article;
• ejection moving means for transmitting rotational power to and causing motion of said movable ejection means, said ejection moving means connected with said movable ejection means and positioned adjacent said movable ejection means;
• initial source means for converting said relative motion into power for powering said ejection moving means, said initial source means providing power sufficient to enable said movable ejection means to break said article loose from said mold surface of said second mold half;
• and
• secondary source means for powering said ejection moving means, said secondary source providing sufficient power to enable said movable ejection means to finish the ejection of said article after said article is broken loose from said second mold half.
