ABSTRACT:
An injection molding machine, comprising a frame including a first structural member having a stationary platen supporting a first mold half and a second structural member spaced from and connected with the first structural member; a movable platen supporting a second mold half wherein the movable platen is positioned between the first and second structural member and wherein the first mold half and the second mold half have a mold centerline; a device for moving the movable platen relative the stationary platen for closing the first mold half and the second mold half together, wherein the device for moving is connected with the frame; and a mechanism for adjustably spacing said first and second structural members along a first substantially common plane spaced from the mold centerline. Upon closing the first mold half and the second mold half together, the first structural member and the second structural member are caused to separate at least along the mold centerline. The mechanism for adjustably spacing causes a separation of the first structural member and the second structural member along the first substantially common plane which substantially prevents tipping of the platens and which substantially maintains parallelism between the stationary and movable platens and alignment of the mold halves.
