ABSTRACT:
The present invention enables one hot runner device to be shared between a plurality of molds whose resin inlets are disposed at different positions.This hot runner device discharges supplied molten material to a resin inlet18bof a mold18. A hot runner body42comprises an inlet opening into which the molten material is supplied, an outlet opening from which the molten material is discharged, and a flow passage. The inlet opening is formed at one end, and the outlet opening is formed at the other end. The flow passage connects the inlet opening and the outlet opening. The hot runner body42is driven and moved by a drive mechanism56so that the outlet opening52can make contact with the resin inlet18bof each of a plurality of molds whose resin inlets18bare disposed at different positions. Accordingly, the hot runner device can be commonly used for the plurality of molds whose resin inlets are disposed at different positions.
