An injection mould for moulding heat curable materials has a hot tool plate with an injection channel(7) leading to an injection orifice(8) into the tool cavity and an insulated injection nozzle(5) with a conical tip(15) extending through a bore in the tool plate. At the mouth of the injection channel(7) within the bore is a seating surface against which the nozzle tip(15) presses, the contact between the two being solely along a line to prevent excess heat transfer from on to the other. |
