Abstract
In an injection molding nozzle for an injection molding tool having an opening for receiving the injection molding nozzle, at least a first mounting element of low heat conductivity is firmly connected to the injection molding nozzle so as to permit accurate machining of the mounting element together with the nozzle such that the nozzle can be installed in the opening of the molding tool by an accurate press fit without directly contacting the base body of the molding tool.
Claims7
An injection molding nozzle (1) for an injection molding tool having a base body (3) with an opening (10) receiving the injection molding nozzle (1), said injection molding nozzle (1) having a molding material supply channel (8) with a discharge opening (5) for discharging molding material at one end thereof and an inlet opening (9) at the opposite end, said injection molding nozzle (1) including means (2) for firmly and accurately installing the injection molding nozzle (1) into the opening (10) in the base body (3), comprising at least a first mounting element (2) of a heat conductivity lower than that of the base body (3), said first mounting element (2) being firmly connected to the injection molding nozzle (1) so as to permit machining of the first mounting element (2) together with the injection molding nozzle (1) for accurately dimensioning the first mounting element (2) together with the injection molding nozzle (1).
An injection molding tool including a base body (3) with an opening (10) receiving an injection molding nozzle (1), said injection molding nozzle (1) having a molding material supply channel (8) with an inlet opening (9) at one end thereof and, at the opposite end, a discharge opening (5) for discharging molding material, said injection molding nozzle (1) including means (2) for firmly and accurately installing the injection molding nozzle (1) into the opening (10) in the base body (3), comprising a first mounting element (2) in the area of the inlet opening (9) and a second mounting element (4) in the area of the discharge opening (5) of the molding nozzle (5), said first and second mounting elements (2, 4) having a lower heat conductivity than said base body (3) and being firmly connected to the injection molding nozzle (1) so as to permit machining of the first and second mounting elements (2, 4) together with the injection molding nozzle (1) for accurately dimensioning the mounting elements (2, 4) together with the injection molding nozzle (1), said injection molding nozzle being firmly installed in said base body opening (10) by a press fit via the first and second mounting elements (2, 4) such that the injection molding nozzle is not in direct heat transfer contact with the base body (3).
