Injection molding nozzle guide and sealing ring |
摘要 |
Injection molding apparatus with a guide and sealing ring mounted around the front end of a heated nozzle. The stainless steel ring fits around the nozzle and has fingers which are bent over the front end of the nozzle to hold it in place. A thermocouple element extends through a groove in the ring and is bent into a hole in the front end of the nozzle. One of the fingers is bent over the thermocouple element to hold it in place. The outer surface of the ring has a circumferential beveled surface leading to a ridge which guides the nozzle into place during insertion and provides a secondary seal against melt leakage. A number of rearwardly extending fingers have notches to receive a wire wound around the nozzle to hold the thermocouple element and the ring itself in place.
