Abstract:
A heater clamp for attachment to a plastic injection molding nozzle and for securing to the nozzle a coiled metallic sheath with a heater element therein, the nozzle having a tip end with threads thereon and an opposite base end, the clamp comprising:a) a tube portion with a first end with a first end edge and a second end with a second end edge, the tube sized to extend around the coiled metallic sheath, a slit extending from the first end toward the second end whereby the tube can be flexed radially inward,b) a first ring portion having a first conical surface and a threaded portion, the ring portion engageable with the threads at the tip end of the nozzle whereby the conical surface substantially faces the base portion of the nozzle, the ring moving axially with respect to the nozzle as it rotates when engaged with the threads,c) a second ring portion having a second conical surface positionable opposite the first ring portion at the base portion, whereby with the tube placed intermediate the first ring portion and the second ring portion and with the coiled metallic sheath on the nozzle, the tube is radially compressible by tightening the first ring portion thereby forcing the coiled metallic sheath onto the nozzle.
