Abstract
PURPOSE: To dry the compounded binder and achieve faster setting of casting sand by inserting a vent pipe into the casting sand which has been hermetically sealed of the exposed surface through molding and venting air through the vent pipe thereby removing the moisture contained.
CONSTITUTION: The kneaded sand 8 obtained by mixing 100 parts of silica sand (casting sand), about 2 parts of a binder (e.g., dextrin) and about 2 parts of water is heated to about 100°C and is put in a mold 1 having multiple through-holes 3 of about 0.5 to 1 mm in diameter communicating to the outside. The exposed surface is covered with a plastic film 10 having a hole 9 and a vent pipe 4 having multiple through-holes 5 of about 0.5 to 1 mm in diameter is inserted into the kneaded sand 8 through the hole 9. Next, the valve 6 attached to the vent pipe 4 is opened to suck the air in the mold 1 through a hose 7 thereby extracting this together with the outside air being sucked through the through-holes 3 of the mold and removing the moisture contained in the kneaded sand 8. The binder is thereby dried and the kneaded sand 8 set.
