Flask mating misalignment detection method and detection device for molds with flasks

A flask mating misalignment detection device for molds with flasks incorporated into an automatic flask mating device that automatically flask-mates a cope with a cope molding flask and a drag with a drag molding flask molded by a molding machine, wherein:

• the cope with the cope molding flask and the drag with the drag molding flask comprise a positioning means comprising pins and bushings;
• and
• the flask mating misalignment detection device for molds with flasks comprises:
• a physical quantity detection sensor configured to detects a force generated when the cope with the cope molding flask is lowered toward the drag with the drag molding flask and the pins and bushings are fitted together;
• and
• a processor configured to function as:
• a computation unit configured to computes a fitting force on the basis of the force detected by the physical quantity detection sensor;
• and
• a determination unit configured to determine whether the flask mating has normally completed on the basis of the fitting force, which is a computation result of the computation unit.
