Abstract

In a method of controlling the temperature of an injection or diecasting mold, the respective temperature of the mold being detected by at least one sensor and compared to a set point and coolant, in particular cooling water, being metered and added through cooling channels disposed in the mold in dependence on detected overshooting or undershooting of the set point, it is provided, with a view to avoiding any overswinging of the control, that opening the valves for metering the coolant is allocated to one threshold and closing the valves to the other.
