Method for moving a movable platen

A molding machine comprising:

• a machine frame extending along a longitudinal axis of the molding machine;
• a stationary mold mounting plate arranged on the machine frame, the stationary mold mounting plate being oriented at a right angle relative to the longitudinal axis of the molding machine;
• a movable mold mounting plate being movable relative to the machine frame, the movable mold mounting plate also being oriented at a right angle relative to the longitudinal axis of the molding machine;
• a drive device for moving the movable mold mounting plate;
• at least two guiding tie bars penetrating the stationary mold mounting plate and the movable mold mounting plate;
• an injection device for injecting plastic melt into a cavity of a molding tool mounted to the stationary mold mounting plate and the movable mold mounting plate;
• a detecting device configured to detect a value representing an amount of tilt of at least one of the stationary mold mounting plate and the movable mold mounting plate from the right angle relative to the longitudinal axis of the molding machine during a travelling movement of the movable mold mounting plate;
• and
• a controller configured to:
• compare the value representing the amount of tilt with a comparative value;
• and
• output an exceeding signal when the value representing the amount of tilt reaches or exceeds the comparative value,
• wherein the detecting device is configured to perform detection of the value representing the amount of tilt during a braking movement of the movable mold mounting plate during closing.
