Abstract
A mold molding apparatus can successively mold casting molds having the necessary casting mold strength, and a method for controlling the mold molding apparatus. A molding sensor measures a pressure of molding sand exerted on a surface of one or both of a pattern plate and a squeeze foot, or on a surface of one or both of a pattern plate and a squeeze board; and a control device that controls operation of the mold molding apparatus based on outputs from the molding sensors.
Claims22
A mold molding apparatus comprising:
- at least one molding sensor that measures a pressure of molding sand exerted (i) on a surface of one or both of a pattern plate and a squeeze feet, or (ii) on a surface of one or both of the pattern plate and a squeeze board, the at least one molding sensor being disposed on the surface of one or both of the pattern plate and the squeeze feet, or on the surface of one or both of the pattern plate and the squeeze board, the molding sand coming into contact with the respective surface;
- a strength computation unit that computes a casting mold strength based on an output from the at least one molding sensor;
- and
- a control device that controls operation of the mold molding apparatus based on the casting mold strength computed by the strength computation unit.
