摘要： By mixing, stirring and kneading, with water glass (11) as a binder, sand (7), a surfactant (9), and water (10), foamed sand (S) is generated. The foamed sand (S) is packed in a cavity of a metallic mold and solidified to form a sand mold. By using the sand mold, aluminum is cast. By using water glass that is an inorganic binder, during casting, harmful gas and odor are not generated. Further, when a molar ratio n of water glass (Na2O nSiO2 mH2O) is adjusted in the range of 0.65 to 1.30, a quantity of water (H2O) generated by heating water glass with a high temperature melt during casting can be suppressed. Thereby, hydrogen gas (H2) according to a reaction between water (H2O) and aluminum (Al) can be suppressed from being generated and casting quality can be improved.

摘要： A device for forming foamed kneaded material and a method for forming foamed kneaded material are obtained capable of filling a pattern forming space of a mold with foamed kneaded material in a well foamed condition. First, a supply device supplies a foamed kneaded material (a) into a cylinder (20) (first process). Then, in a state in which an internal space (22) of the cylinder (20) is communicated with a pattern forming space (14) of a mold (12), the piston (26) disposed in the cylinder (20) is moved toward the foamed kneaded material (a) side while opening a gas release hole (40A) formed piercing through the piston (26) (second process). Then, at a timing when the piston (26) has reached an expected position (X) where the piston (26) is expected to be on contacting the foamed kneaded material (a) supplied into the cylinder (20), the gas release hole (40A) is closed by an open-close plug (40B) (third process). Then, the foamed kneaded material (a) supplied into the cylinder (20) is pressed toward the pattern forming space (14) side of the mold (12) by moving the piston (26) toward the foamed kneaded material (a) side (fourth process).

摘要： A core manufacturing apparatus includes: a storage unit (20) that stores core sand; a kneading vessel (11) configured to be fed with the core sand; a kneading rod (12) configured to knead the core sand; and a piston (14) configured to eject the kneaded core sand. The kneading vessel (11) is capable of transitioning between a horizontally lying state and a vertically standing state and configured to be fed with the core sand in the horizontally lying state. The piston (14) is configured to eject the core sand downward and pack it into a mold with the kneading vessel (11) in the vertically standing state. The storage unit (20) includes a valve (V3) that opens and closes the feed port (11a). The storage unit (20) is coupled to the kneading vessel (11) so as to be turnable around a second shaft (A2) and configured to maintain the same posture with the valve (V3) in contact with the feed port (11a) while the kneading vessel (11) turns.

摘要： There are provided a device and a method allowing that the surface of an admixture in a stirring tank pressed by a packing device is smoothed with a simple structure whereby a casting mold is precisely molded. A mold-making device includes a stirring device 3 that has a stirring tank 1 and stirring blades 2 and stirs a particulate aggregate and an additive(s) to yield an admixture M, a forming mold 4 that molds the admixture M into a predetermined shape, and a packing device 5 that compresses a surface of the admixture M within the stirring tank 1 and packs it into the forming mold 4. The stirring blades 2 are configured in a lattice pattern by a plurality of horizontal members 21 and a plurality of vertical members 22. A distal end of a rotating drive shaft 23 is bonded to the top edge of the stirring blades 2, and the rotating drive shaft 23 is configured so that it is not immersed into the admixture M. Scrapers 29 for smoothing out the surface of the admixture M are provided on the bottom of the stirring blades 2.
