The invention relates to a method for injection moulding of thermoplastic pole parts, with the use of a mould in which at least one vacuum interrupter and contact terminals are fixed during the moulding procees, and with at least one injection opening or gate for injection of thermoplastic material into the mould, and mould for proceeding the same, according to the preamble of claims 1 and 9. In order to solve the problem with a pressure gradient along the long axis of the moulded pole part, and to result in shorte process times as well as in a homogenous dissipation of material during the moulding process, the mould is applied with multiple injection openings at least along its long axis, for injection of hot thermoplastic material, and that the injection openings or gates can be steared in such a way, that they inject thermoplastic material simultaneously or with a defined time dependend injection pattern.
