Abstract

In an injection moulding machine having an injection block with a nozzle through which moulding material is supplied in paste-like form, a mould having fixed and moving forces together with a mould element connected with the injection nozzle by a passage in the fixed force, the passage is provided with a controlled leakage device mechanically linked to the surface of a motorised cam. The device enables the pressure at any moment in the mould to be controlled according to a predetermined scheme. Independent devices may be fitted to each mould.
