CANNULAR FEEDING APPARATUS

摘要

An apparatus for feeding hypodermic needles into corresponding recesses of a mold cavity in the bottom mold plate of a plastic injection molding machine. The bottom mold plate can be shifted from a molding position to a loading position at one side of the machine. At that side of the machine, a magazine holding two stacks of hypodermic needles is slidably adjustable horizontally with respect to a shuttle plate mounted on that side of the machine. The magazine at the bottom has lower and upper plates slidable respectively across the bottom and top of the shuttle plate. In one position of the magazine, openings in its upper bottom plate register with corresponding openings in the shuttle plate to pass individual needles by gravity into the shuttle plate. In another position of the magazine, openings, in its lower bottom plate register with corresponding openings in the shuttle plate to pass individual needles by gravity from the shuttle plate into corresponding recesses of the mold cavity when the bottom mold plate is in its loading position.
