    Abstract: An opening portion (34) that is formed so as to pass-through an opening/closing plate portion (32) of a gate (30), can be disposed at a region overlapping a lower end opening (24A) of a hopper (20). The opening portion (34) is structured by a first pass-through portion (34A), and a second pass-through portion (34B) that is formed so as to be continuous with the first pass-through portion (34A). A width, in a direction orthogonal to a lined-up direction in which the first pass-through portion (34A) and the second pass-through portion (34B) are lined up, is narrower than the first pass-through portion (34A). Further, a driving mechanism (40) moves the gate (30) such that the opening/closing plate portion (32) moves in the lined-up direction as seen in a plan view. Based on a preset target value of weight of sand, a control section (18) controls the driving mechanism (40) so as to decrease an amount of overlap of the opening portion (34) of the gate (30) and the lower end opening (24A) of the hopper (20) in a stepwise manner in accordance with an increase in the weight of the sand measured by a scale.

    Abstract: When pressing kneaded sand in a kneading sand tank into a mold by a pressing member, a pressing force applied to a kneaded sand layer in the kneading sand tank is monitored and a moving position of the pressing member is monitored from when the pressing member starts to move. A pressing start time at which the kneaded sand starts to flow into the mold is identified based on the pressing force applied to the kneaded sand layer in the kneading sand tank, and a pressing starting position of the pressing member at the pressing start time is identified. As a result, the pressing start time and the pressing starting position of the pressing member when the kneaded sand starts to flow into the mold are accurately identified, so the reliability of a filling evaluation of the kneaded sand into the mold is improved.

    Abstract: A sand-mold molding method for producing a molded article obtained by packing foamed sand may include stirring a binder with an aggregate to form foamed sand; forming a cavity via clamping a metallic mold closed; packing the foamed sand into the cavity of the metallic mold and then heating and solidifying the foamed sand; and opening the metallic mold partially to provide a gap in the metallic mold while maintaining the cavity.

    Abstract: First, a supply device supplies a foamed kneaded material into a cylinder. Then, in a state in which an internal space of the cylinder is communicated with a pattern forming space of a mold, the piston disposed in the cylinder is moved toward the foamed kneaded material side while opening a gas release hole formed piercing through the piston. Then, at a timing when the piston has reached an expected position where the piston is expected to be on contacting the foamed kneaded material supplied into the cylinder, the gas release hole is closed by an open-close plug. Then, the foamed kneaded material supplied into the cylinder is pressed toward the pattern forming space side of the mold by moving the piston toward the foamed kneaded material side.

    Abstract: To provide an apparatus for reclaiming foundry sand and a method for reclaiming foundry sand that can effectively remove binders and so on that attach to returned foundry sand that has been used. Foundry sand that has been used is supplied from a chute for feeding sand 14A to a rotor 16. The rotor 16 is rotated by a driver 20 so that frictional force is generated on the sand in the rotor 16. Then, the sand in the rotor 16 is dropped into the container for washing with water 30 that is located below the rotor 16. In the container for washing with water 30, an agitator 34 is rotated by the driver 20 so that the sand in the container for washing with water 30 is agitated and washed with water.
