  • Patent number: 4084931
    Abstract: Injection plastic molding apparatus comprising a pair of dies movable horizontally relative to one another between a closed molding position and an opened position. A nozzle is engageable with the dies for injecting plastic into the cavities thereof when the dies are in closed position to form a part. A hot wire is mounted on one of the dies such that when they are moved relative to one another to an open position, the hot wire will engage any drool of plastic which may occur between the nozzle and the part. Means are provided for energizing the wire at a temperature sufficient to melt and sever the drool permitting the part to fall under the action of gravity.
