The additive composition of the present invention is one blended in a sand composition which is subjected to foaming to mold a sand mold, and includes (A) an alkylsulfonate metal salt having an alkyl group with 9 to 22 carbon atoms. The additive composition may further include at least one component selected from a group consisting of (B) an alkylsulfate metal salt, (C) a polyoxyalkylene alkyl ether sulfate metal salt, and (D) an alkylbenzene sulfonate metal salt.

Additive for forming sand mold, sand composition for forming sand mold, method for producing sand mold, and sand mold

The invention relates to a composition for forming a casting mold, the composition containing heat-resistant inorganic particles; a waterglass-based binder; a surfactant; a silicon-containing compound; activated carbon powder and grain; and water; and the silicon-containing compound contains at least one of metal silicon and ferrosilicon.

Composition for forming casting mold and casting mold forming method

The present invention includes: an injection container unit; a lid member; and an ejection air supply section configured to press a foamed mixed material in the injection container unit with compressed air and thereby eject the foamed mixed material through an ejection port, the lid member being provided with a sealing body configured to deform when a fluid is injected and thereby make close contact with the inner circumferential surface of the injection container unit during the pressing.

Molding machine

A casting mold making apparatus and a method employing a tank with a pour hole formed at a bottom wall of the tank and an opening section open toward the opposite side to a bottom wall side. A first process of the method includes stirring component materials inside the tank with a stirring impeller so as to make a foam mixture while an opening section side of the tank is closed and the pour hole is closed. The second process is performed after the first process and includes opening the pour hole, pressing the tank against a mold such that a fill hole formed so as to pass into the mold is disposed adjacent to the pour hole, and supplying compressed air into the tank while stirring the foam mixture inside the tank with the stirring impeller so as to fill the foam mixture into a cavity of the mold.

Casting mold making apparatus and mold making method

The present invention includes: a connector unit configured to disconnectably connect an injection container unit and a lid member; and a vertically driving mechanism configured to cause the injection container unit and the lid member to move up and down together when the injection container unit and the lid member are connected together and to cause the lid member to move up and down when the injection container unit and the lid member are not connected together.

An expandable aggregate mixture for a mold, which contains an aggregate, a water-soluble binder, a water-soluble foaming agent, water, and spherical metal oxide particles.

Expandable aggregate mixture for molds, mold, and method for manufacturing mold

To provide a binder composition for molding, by which a mold made of aggregate has an excellent resistance to moisture. The binder composition for molding contains a water-soluble binder and at least one kind of lithium salt that is selected from a group of lithium silicate, lithium oxide, lithium hydroxide, lithium carbonate, lithium bromide, lithium chloride, lithium nitrate, and lithium nitrite.

Binder composition for molding, blended aggregate for molding, and mold

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 sandA to a rotor. The rotoris rotated by a driverso that frictional force is generated on the sand in the rotor. Then, the sand in the rotoris dropped into the container for washing with waterthat is located below the rotor. In the container for washing with water, an agitatoris rotated by the driverso that the sand in the container for washing with wateris agitated and washed with water.

Apparatus and a method for reclaiming foundry sand

Sand for a casting mold including sand, a binder, and an inorganic compound particle having poor water solubility and generating a gas, which is at least one of water vapor or carbon dioxide gas, by heat from a molten metal.
