Abstract
A molding system molding a sand mold includes 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, during sand filling in which the sand in the tank is introduced into the flask through the nozzle, a relationship where arrival time from the start of sand filling until the pressure reaches a predetermined pressure is shorter than the initial arrival time obtained in advance is satisfied.

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 arrival time from a start of sand filling until a pressure reaches a predetermined pressure is shorter than an initial arrival time obtained in advance.
A molding method, comprising:
- a step of introducing sand in a tank into a flask from the tank through a nozzle, the tank being connected to a compressed air source, including an opened end part, and internally storing the sand, the nozzle being attached to the end part of the tank;
- and
- a step of outputting information about clogging of the nozzle when a relationship where arrival time from a start of sand filling until a pressure reaches a predetermined pressure is shorter than an initial arrival time obtained in advance is satisfied in the step of introducing the sand into the flask.
