Description

Large Gate Sprue Bushings

A sprue bushing for mold sets is described for use with injection molds employing three plates to permit easy stripping of runners and sprue portions from products molded therein. This nozzle sprue bushing is adapted to receive an injection nozzle while mounted in a first or top plate.

This sprue bushing has an extending portion that mates and seats in a tapered recess in a second bushing carried by the second or stripper plate. The nozzle sprue bushing has a sprue passageway that terminates at the top plate of the mold. The extension nozzle of the injection press seats within a radiused portion formed in the recessed sprue bushing.

The extension of the sprue bushing which seats in the runner plate bushing is preferably exactly the length of the stripper or runner plate bushing which is carried in the runner or stripper plate of a tri-plate mold set. The sprue is very short and, as reduced to practice, remains with the runner sprue which is usually separated from the molded piece during removal of the molded unit from the mold cavity.
