Injection nozzle of adjustable length
Abstract
Abstract GIANT ARTICLES ARE SOMETIMES SO SHAPED THAT THE ORIFICES TO BE SECURED TO THE NOZZLES OF A MULTI-NOZZLE INJECTION MOLDING MACHINE SHOULD DESIRABLY BE POSITIONED AT DIFFERENT DISTANCES FROM THE FRAME OF THE MOLDING MACHINE INSTEAD OF THE CONVENTIONAL UNIFORM DISTANCE. THREADABLE ADJUSTABLE MEMBERS PERMIT ADJUSTMENT OF LENGTH OF INJECTION NOZZLE THROUGHOUT A RANGE SUCH AS ONE CENTIMETER WITH A ZONE OF CLOSE TOLERANCE SLIDING CONTACT BEING LOCKED INTO NON-LEAKING AND NON-ROTATIONAL RELATIONSHIP BY THE ACTION OF RELATIVELY HIGH PLASTIC PRESSURE. SUCH PRESSURE INFLUENCED ZONE, A PLURALITY OF O-RINGS, AND WEEP HOLES PREVENT ANY PLASTIC FROM SWEEPING TO THE ADJUSTABLE THREADS. FURTHER MEMBERS WHICH CAN BE INSERTED AND SECURED BY COUPLERS FOR LENGTHENING A NOZZLE.
