<p>1. A tool temperature control method for the moulding tools of injection moulding machines wherein provided in the moulding tools are conduit circuits for a cooling agent, as well as conduits for the feed flow and the return flow of the cooling agent, with valves with which the through flow of the cooling agent can be controlled, and at least one temperature sensor on the moulding tool, which is connected to a computer, for example a microprocessor, characterised in that the computer (7) controls the closing and opening of the valves (4) as a function of a temperature difference in the moulding tools (1, 2) after a measuring period with valves (4) in the condition of maximum opening and a measuring period with valves (4) closed.</p> |
