Abstract
Abstract THE MOVABLE PLATEN OF AN INJECTION-MOLDING MACHINE, SECURED TO A SET HORIZONTAL PISTON RODS, IS RESTED ON A TRACK PROJECTING ENDWISE BEYOND THE MACHINE BED, THERE BY SIMPLIFYING THE COLLECTION OF MOLDED ARTICLES EJECTED IN THE OPEN-MOLD POSITION. THE TRACK MAY BE SIMPLY CANTILEVERED OR BRACED, PREFERABLY ADJUSTABLY, AGAINST THE MACHINE FRAME. TO COMPENSATE FOR POSSIBLE DEFLECTION OF THE CANTILEVERED TRACK UNDER THE WEIGHT OF THE PLATEN, ITS WORKING SURFACE MAY BE SLIGHTLY INCLINED SO AS TO RISE WITH INCREASING DISTANCE FROM THE BED, ALTERNATIVELY, AN EXPANDING BRACE MAY BE INTERPOSED BETWEEN THE TRACK AND THE PLATEN TO HELP MAINTAIN THE LATTER ON A HORIZONTAL GUIDE PATH.
