Abstract
An injection molding machine includes a stationary platen and a moving platen mounted on a machine base, and a rotary apparatus for rotatably supporting a center mold section. The rotary apparatus includes a carriage body including a carriage upper portion supported by first and second carriage rails, and a carriage lower portion extending downward from the carriage upper portion laterally intermediate the first and second carriage rails. The rotary apparatus further includes a rotary table mounted atop the carriage body for rotatably supporting the center mold section. The rotary table is mounted to the carriage body by a rotary table bearing having a combination of bearing elements to bear axial, rotational, and moment loads. The machine further includes a plurality of tie bars extending between the moving platen and the stationary platen. The tie bars are free from engagement by the rotary apparatus.
