Mold positioning device

A structure for positioning a first mold part of a mold on a mold mounting face in an injection molding machine, the structure comprising:

• a plurality of sensors associated with the first mold part, each sensor configured to provide a feedback signal including an alignment parameter that includes:
• a position of the first mold part in relation to the mold mounting face of a first platen of the injection molding machine, and/or
• a position of the first mold part in relation to a second mold part that is associated, in use, with a second platen of the injection molding machine;
• a positioner that is configured to connect the first mold part to the first platen of the injection molding machine, wherein the positioner is adjustable to position the first mold part in relation to the mold mounting face;
• a controller configured to receive the feedback signal from each sensor;
• controller executable instructions that when executed by the controller, cause the controller to:
• resolve an alignment parameter of the mold using the feedback signal from each sensor,
• determine an alignment correction having regard to the alignment parameter, the alignment correction defining a displacement of the first mold part along a first axis in relation to the mold mounting face, and
• control the positioner in accordance with the alignment correction;
• wherein the positioner is configured to hang the first mold part from the top of the first platen of the injection molding machine;
• and
• wherein, in use, the first platen is movable along a second axis relative to the second platen for opening and closing the mold, the second axis being different from and transverse to the first axis.
