Abstract:
1. An injection nozzle for plastic injection moulding equipment, including a body ( 1 ) with a central passageway ( 2 ) and a nozzle tip ( 4 ) including an internal hollow element ( 5 ) made of a material with high thermal conductivity and an external hollow element ( 6 ) made of a material with a lower thermal conductivity, wherein said internal hollow element ( 5 ) is positioned between said central passageway ( 2 ) and said external hollow element ( 6 ), said internal hollow element ( 5 ) being connected to one end of said body ( 1 ) of the injector nozzle independently with respect to said external hollow element ( 6 ) and an air space of mutual separation ( 19 ) being defined between said external hollow element and ( 6 ) said internal hollow element ( 5 ), wherein said air space of mutual separation ( 19 ) is also provided in correspondence of said one end of the injector nozzle body ( 1 ), whereby said external hollow element ( 6 ) and said internal hollow element ( 5 ) are spaced apart from each other in the area of said one end of the body ( 1 ) so as to expose a surface of said one end of the body to said air space of mutual separation.
