Abstract
In a method for tempering an injection molding tool having a plurality of cooling conduits, in which a coolant liquid can be introduced in controlled fashion, wherein the injection molding tool has a mold recess into which molten molding composition is injected during an injection cycle and is ejected after solidifying, it is provided in order to optimize the heat dissipation that the cooling conduits are positioned parallel relative to the closest wall of the mold recess in such a way that the thermal energy to be dissipated in the injection cycle, resulting from the sum of the thermal energy of the part to be molded and heat exchange with the surroundings of the tool and the externally supplied energy, can be carried away maximally in the time of the heat transfer from the melt to the tool wall.
