Green sand mold forming sensor and green sand mold formability evaluation method

A casting mold molding machine comprising a frame-shaped carrier, a green sand mold molding sensor comprising a pressure sensor for evaluating moldability of a green sand mold molded by the casting mold molding machine, a plate that is placed inside the frame-shaped carrier, and a model attached to the plate,

• wherein a plurality of the pressure sensors are embedded in the plate,
• a pressure-receiving surface of the plurality of the pressure sensors and a surface of the plate are in a flush state,
• the plate is separated into a central plate having the model attached thereto and a peripheral plate in which the pressure sensors are embedded,
• the frame-shaped carrier holds the peripheral plate and the central plate inside the frame-shape,
• the peripheral plate includes a peripheral portion in which the pressure sensors are embedded and an opening portion that is surrounded by the peripheral portion, and is provided with a stepped surface on an inner periphery thereof, and
• the central plate is provided with a stepped surface corresponding to the stepped surface of the opening portion on an outer periphery thereof, and is fixed inside the opening portion by a bolt so as to be attachable and detachable,
• wherein the peripheral plate is rectangular, each of the pressure sensors is embedded in one of the four corners of the peripheral plate, and all of the pressure sensors are disposed at a same height on the peripheral plate.
