An apparatus for regulating an injection moulding machine comprising a crank lever mechanism for moving the movable mould mounting plate, wherein the crosshead of the crank lever mechanism is driven by a drive device. The regulating apparatus is constructed as a cascade regulator, wherein the follower regulating circuit (inner regulating circuit ( 11 )) is a force regulator which compares a force reference value (F<SUB>Href</SUB>) supplied by a guide regulating circuit to a force actual value (F<SUB>H</SUB>) detected by a force measuring device ( 14 ) at the drive device ( 5, 6 ) and outputs a control parameter or parameters to the drive device ( 5, 6 ), and wherein the guide regulating circuit (outer regulating circuit ( 9 )) is a trajectory follower regulator which in dependence on a stored or generated reference trajectory (x<SUB>C,ref</SUB>,{dot over (x<SUB>C,ref</SUB>,x<SUB>C,ref</SUB>) for the crosshead ascertains and outputs on the one hand a travel and/or speed actual value (x<SUB>C</SUB>,{dot over (x<SMALLCAPS>C</SMALLCAPS>) detected by a travel measuring device ( 12 ) at the crosshead ( 4 ) and on the other hand the force reference value (F<SUB>H,ref</SUB>) for the follower regulating circuit.
