摘要： When a molded article is obtained by which foamed sand is packed into a metallic mold, heated and solidified, vapor and gas that have been generated through the heating and solidification of the foamed sand are smoothly discharged from the cavity.
A cavity C is formed by clamping a metallic mold 2, and foamed sand S is packed into the cavity C. When heating and solidifying the foamed sand S, a mold clamping force is reduced to form a slight gap L in the metallic mold 2 while maintaining the cavity C. Gas and water vapor that are generated when heating and solidifying the foamed sand S can be smoothly discharged from within the cavity C to the outside through the gap L, and thus the baking time of the foamed sand S can be shortened. Even if solidified binder accumulates on slits 16, gas and water vapor can be reliably discharged from within the cavity C to the outside via the gap.
摘要翻译：当获得将发泡砂填充到金属模具中的模制品时，加热并固化，通过发泡砂的加热和固化而产生的蒸气和气体顺利地从模腔中排出。通过夹持金属模具2形成空腔C，并将泡沫沙S填充到空腔C中。当加热并固化泡沫沙S时，模具夹紧力减小，从而在金属模具2中形成微小间隙L 保持空腔C.在加热并固化发泡砂S时产生的气体和水蒸气可以通过间隙L顺利地从空腔C内排出到外部，因此可以缩短泡沫砂S的烘烤时间。即使固化的粘合剂积聚在狭缝16上，气体和水蒸气也能够经由间隙可靠地从空腔C内排出到外部。

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： 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.
