Abstract: In one aspect, an injection unit for an injection molding machine having a hot runner with a sprue comprises a heated melt pipe configured to convey a continuous stream of melt, a shooting pot assembly, and a telescopic melt coupling. The shooting pot assembly is configured to convert the continuous stream of melt from the heated melt pipe into batches for cyclical injection and is translatable between a sprue-engagement position and a sprue-disengagement position. The telescopic melt coupling is configured to convey melt from the heated melt pipe to the shooting pot assembly and has a variable length. The variable length telescopic melt coupling permits translation of the shooting pot assembly, relative to the heated melt pipe, between the sprue-engagement position and the sprue-disengagement position while maintaining a fluid melt interconnection between the heated melt pipe and the shooting pot assembly.
