Abstract
An injection nozzle for plastic injection moulding equipment having a nozzle tip (4) with 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. The internal hollow element (5) is connected to the body (1) of the injector nozzle independently with respect to the external hollow element (6), and a space of mutual separation (19) is defined between the internal and external hollow elements (5, 6).
Claims10
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 one end (12) of the said external hollow element (6) has a thread (13) that can engage with a corresponding thread (14) on the body (1) of the injector nozzle and, at the other end (15), a part providing sealed contact (18) with the injection mould (M), and wherein the internal hollow element (5) is positioned between the said central passageway (2) and the said external hollow element (6), said internal hollow element (5) being connected to said body (1) of the injector nozzle independently with respect to the said external hollow element (6), and a space of mutual separation (19) being defined between the said external hollow element and (6) the said internal hollow element (5).
