A method is provided for moving a movable mold mounting plate of a molding machine, in which the movable mold mounting plate is movable relative to a stationary mold mounting plate and the mold mounting plates are kinematically connected to each other, and in which a drive mechanism for moving the movable mold mounting plate is provided. Molding tool parts arranged on the mold mounting plates are brought into abutment to each other in a closed state, and a temporally changeable tilting movement of the mold mounting plates relative to each other occurs by the movement of the movable mold mounting plate. The movable mold mounting plate is moved by the drive mechanism and/or the stationary mold mounting plate is moved by an injection device in such a way that when reaching a predeterminable distance of the mold mounting plates relative to each other, a parameter representing the tilting movement of the mold mounting plates relative to each other is less than or equal to a presettable value, preferably equal to zero.
