         3 . The green sand mold molding sensor according to  claim 1 , wherein a pressure-receiving surface of the pressure sensor and a surface of the plate are in a flush state. 
     
     
         4 . The green sand mold molding sensor according to  claim 1 , wherein the pressure sensor is embedded between the wall of the metal flask and the model in the plate at the time of green sand mold molding. 
     
     
         5 . The green sand mold molding sensor according to  claim 1 , wherein the plate is configured to be rectangular, a plurality of the pressure sensors are provided, and these pressure sensors are embedded in the four corners of the plate. 
     
     
         6 . The green sand mold molding sensor according to  claim 1 , wherein the plate having the model attached thereto is divided into a central part having the model attached thereto and a peripheral part having the pressure sensor embedded therein, and the central part of the plate having the model attached thereto is configured so as to be attachable and detachable. 
     
     
         7 . The green sand mold molding sensor according to  claim 1 , wherein the casting mold molding machine is a flask molding machine and the plate is placed on a carrier. 
     
     
         8 . The green sand mold molding sensor according to  claim 1 , wherein the casting mold molding machine is a flaskless molding machine and the model is attached to both surfaces of the plate. 
     
     
         9 . The green sand mold molding sensor according to  claim 8 , wherein the casting mold molding machine is a flaskless molding machine and the plate is placed on a shuttle dolly. 
     
     
         10 . The green sand mold molding sensor according to  claim 1 , wherein the pressure sensor is fixed to the plate by a screwing means. 
     
     
         11 . The green sand mold molding sensor according to  claim 1 , wherein the pressure sensor is a fluid sensor. 
     
     
         12 . The green sand mold molding sensor according to  claim 1 , wherein the pressure sensor has a pressure-receiving surface that is 5-30 mm in diameter. 
     
     
         13 . A method for evaluating green sand mold moldability, wherein moldability of a green sand mold molded by a casting mold molding machine is evaluated by using a green sand mold molding sensor comprising a pressure sensor embedded in a plate having a model attached thereto.
