A casting mold molding machine includes 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.

A green sand mold molding sensor that can measure the pressure applied to a parting plane of a green sand mold in order to determine the quality (casting mold strength) of a molded green sand mold. A green sand mold molding sensor including a pressure sensor for evaluating the molding properties of a green sand mold molded by a casting mold molding machine, wherein the pressure sensor is embedded in a plate having a model attached thereto.

A casting mold molding device, a casting mold quality evaluation device, and a casting mold quality evaluation method are capable of evaluating the quality (casting mold strength) of a molded green sand mold without measuring a green sand mold by using a casting mold strength gauge each time a green sand mold is molded in one frame. A green sand mold molding sensor that, during molding of a green sand mold, measures a pressure value applied to a joining section between green sand introduced into a casting mold molding space and a plate having a model attached thereto; and a casting mold quality evaluation device that evaluates the quality of a molded green sand mold from the pressure value.

A flask for containing mold sand within it prevents any mold shifting or mold dropping. Each of an upper flask 2 and a lower flask 3 includes a body that defines an opening in which a sand mold is to be molded. The body has at least one inlet 101 for introducing the mold sand into the opening. Two flanges 102 are extended from the body such that they are opposed to each other across the opening. Each flange has a through bore. The flask also includes engaging members for engaging an actuator in the outside of the flask such that a force or forces from said actuator could be transmitted to the flask. An upper flask 104 and a lower flask 105 are opposed to each other across a pattern plate 107. They are integrally assembled to make a flask unit by means of a pair of connecting rods 106 that are fitted in each bore.

[Problem] To provide a method and device that automatically detects misalignment during flask mating in an automatic flask mating device for molding flasks for casting. [Solution] In an automatic flask mating device, an external force applied to a cope with a cope molding flask M1 during flask mating is detected by means of a physical quantity detection sensor 60, quantified by a computation/storage/determination processing device 61, and then compared with a numerical value at a normal time for determination to thereby determine whether the flask mating has normally completed and detect flask mating misalignment. A force sensor is preferably used as the physical quantity detection sensor.
