Abstract
A method for operating an injection-molding machine, including the steps: a) in a current injection-molding cycle, after an accepted-part reference injection-molding cycle learned in a learning phase: detecting a compound pressure change krelative to an accepted-part reference compound pressure pduring at least part of an injection phase of the current injection-molding cycle by measuring a current compound pressure pand comparing the current compound pressure pwith the accepted-part reference compound pressure p, b) determining a target mold internal pressure curve p(t) for a holding-pressure phase of the current injection-molding cycle, wherein for this purpose a mold internal pressure curve p(t) of the accepted-part reference injection-molding cycle is adjusted at least in dependence on the compound pressure change kdetected in step a), and c) traveling the holding-pressure curve p(t) of the current injection-molding cycle in such a way that an actual mold internal pressure curve pwkz,act (t) of the current injection-molding cycle runs at least more closely along the target mold internal pressure curve p(t) than a mold internal pressure curve p(t) that is unchanged in comparison with the accepted-part reference cycle.
