Hot runner nozzle for injection molding tool, used for supplying flowable plastic melt to mold insert, has thermocouple element that is guided through opening in cuff wall at transition region provided between respective regions

摘要

The hot runner nozzle has a thermocouple element (30) that is arranged in region (B1) of end (11) of material pipe (10). The thermocouple element is moved toward the end (12) of material pipe. The thermocouple element is pinched between material pipe and inner surface of cuff (20) in region (B1). The thermocouple is moved towards outer surface (23) of cuff in region (B2). The thermocouple element is guided through the opening (26) in cuff wall (31) at transition region (B3) provided between respective regions (B1,B2).
