1. A molding system molding a sand mold, the molding system comprising:
a flask;
a tank connected to a compressed air source, including an opened end part, and configured to internally store sand;
a nozzle attached to the end part of the tank and configured to guide the sand in the tank into the flask; and
a control unit configured to output information about clogging of the nozzle when a relationship is satisfied during sand filling in which the sand in the tank is introduced into the flask through the nozzle, the relationship where pressure inside the tank is higher than initial pressure during the sand filling in which the sand is introduced into the flask.
 
9. A molding system molding a sand mold, the molding system comprising:
a flask;
a tank connected to a compressed air source, including an opened end part, and configured to internally store sand;
a nozzle attached to the end part of the tank and configured to guide the sand in the tank into the flask; and
a control unit configured to output information about clogging of the nozzle when a relationship is satisfied during sand filling in which the sand in the tank is introduced into the flask through the nozzle, the relationship where pressure change inside the tank is greater than initial pressure change during the sand filling in which the sand is introduced into the flask.
