A co-injection hot runner nozzle comprises an inner melt flow channel and an annular outer melt flow channel that surrounds the inner melt flow channel. The inner and outer melt flow channels have a first common source. The nozzle further comprises an annular intermediate melt flow channel disposed between the inner and outer melt flow channels. The annular intermediate melt flow channel is at least partly defined by a plurality of spiral grooves, each spiral groove having a respective inlet and defining a helical flow path. Lands between adjacent spiral grooves increase in clearance in a downstream direction. An annular axial flow path is defined over the lands. A plurality of feeder channels having a second common source is configured to supply melt to the plurality of inlets of the spiral grooves. The relationship of feeder channels to spiral grooves may be one-to-one. The inlets may be longitudinal channels.

There is provided a structure for positioning a first mold part of a mold on a mold mounting face in an injection molding machine. The structure comprises a positioner configured to connect the first mold part to part of the injection molding machine, wherein the positioner is adjustable to position the first mold part on the mold mounting face. The structure further comprises controller executable instructions executable in a controller with which to resolve an alignment parameter of the mold using a feedback signal from a sensor. Further provided is a method of operating an injection molding machine which method comprises the steps of positioning a first mold part of a mold on a mold mounting face using a positioner and appreciating an alignment parameter of the mold with reference to a feedback signal from a sensor.

Mold positioning device

Disclosed herein, amongst other things, are structure and steps for positioning a first mold part of a mold on a mold mounting face in an injection molding machine. In particular, the structure and steps may include a positioner that is configured to connect the first mold part to part of the injection molding machine, wherein the positioner is adjustable to position the first mold part across the mold mounting face.
