Green sand mold molding sensor and green sand mold moldability evaluation method

Abstract

A green sand mold molding sensor including a pressure sensor for evaluating moldability of a green sand mold molded by a casting mold molding machine, wherein the pressure sensor is embedded in a squeeze board or squeeze feet that compresses green sand.

1 . A green sand mold molding sensor comprising a pressure sensor for evaluating moldability of a green sand mold molded by a casting mold molding machine, wherein the pressure sensor is embedded in a squeeze board or squeeze feet that compress green sand. 
     
     
         2 . The green sand mold molding sensor according to  claim 1 , wherein the squeeze board or squeeze feet is a member that constitutes a part of a boundary of a molding space defined by the squeeze board or squeeze feet and a metal flask during green sand molding by the casting mold molding machine. 
     
     
         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 squeeze board or squeeze feet are in a flush state. 
     
     
         4 . The green sand mold molding sensor according to  claim 1 , wherein, as a member that constitutes a part of a boundary of a molding space defined by the member and a metal flask during green sand mold molding by the casting mold molding machine, the squeeze board or squeeze feet and a plate having attached thereto a pattern arranged facing the squeeze board or squeeze feet are provided, the pressure sensor being embedded at a corresponding position in the squeeze board or squeeze feet between the metal flask and the pattern. 
     
     
         5 . The green sand mold molding sensor according to  claim 1 , wherein the squeeze board 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 squeeze board. 
     
     
         6 . The green sand mold molding sensor according to  claim 1 , wherein an arrangement of the squeeze feet is configured to be rectangular, a plurality of the pressure sensors are provided, and these pressure sensors are embedded in any of the squeeze feet including the squeeze feet in the four corners. 
     
     
         7 . The green sand mold molding sensor according to  claim 1 , wherein the pressure sensor is fixed to the squeeze board or squeeze feet by a screwing means. 
     
     
         8 . The green sand mold molding sensor according to  claim 1 , wherein the pressure sensor is a fluid sensor. 
     
     
         9 . 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. 
     
     
         10 . A method for evaluating green sand mold moldability, comprising evaluating moldability of a green sand mold molded by a casting mold molding machine by using a green sand mold molding sensor provided with a pressure sensor embedded in a squeeze board or squeeze feet that compresses green sand.
