摘要： The present invention relates to a sprue bar assembly for use with a number of different injection molding machines. The sprue bar assembly comprises a fixed sprue bar section having a first channel through which molten material, such as a plastic resin, flows. The first channel communicates with the outlet of a source of the molten material. The sprue bar assembly further comprises an adjustable sprue bar section having a second channel through which molten material flows and a powered unit for holding the adjustable sprue bar section in contact with the fixed sprue bar section so that molten material can flow from the first channel to the second channel without leaking and for changing the length of the sprue bar assembly as needed to accommodate molds of different shutheights. In a preferred embodiment of the present invention, the fixed sprue bar section and the adjustable sprue bar section are each provided with a valve gate for preventing drooling or leakage of the molten material when the two sections are separated.
