Abstract
A horizontal injection molding machine includes two platens, of which one can be a fixed or a moving platen and the other a moving platen, with the platens moving on horizontal columns, and a mold half carrier which is rotatably supported by a turntable and carries mold halves for injection molding tools. A yoke extends between the upper columns for movement along the upper columns. The mold half carrier has on its top side a pivot pin which engages in an opening of the yoke. This arrangement eliminates or at least reduces forces on the columns due to weight and torques.
Claims23
A horizontal injection molding machine comprising:
- two moving platens constructed for relative movement therebetween;
- a base plate disposed between the two moving platens and constructed for movement in parallel relationship to a longitudinal machine axis;
- a turntable supported on or in the base plate for rotation about a vertical axis;
- a mold half carrier attached to the turntable for carrying mold halves of injection molding tools, said mold half carrier having a topside provided with a pivot pin;
- a plurality of upper and lower columns extending between the fixed and moving platens;
- and
- a yoke extending between the upper columns and movable relative to the upper columns, said yoke having an opening for rotatably accepting the pivot pin of the mold half carrier.
