ABSTRACT:
An injection molding nozzle upon which a thermocouple element can be removably mounted and be self-retained in place. The nozzle has a front portion and a larger diameter rear collar portion with a thermocouple element duct therethrough. A thermocouple element bore extends rearwardly from the front end of the nozzle and a thermocouple element groove extends outwardly across the rear end from the thermocouple element duct. A front portion of a suitably bendable and retentive thermocouple element is inserted into the bore in the front end and bent to extend rearwardly to the duct through the rear collar portion. A rear portion of the thermocouple element is bent into place in the groove in the rear end. The thermocouple element securely retains itself in this position while the nozzle is being installed in the mold.
