Abstract

PURPOSE: To considerably prolong the pot life of a self-hardening mixture by blowing cooling dry gas into areas for feeding and mixing of sand and additives and encircling the respective areas by heat-insultating members.
CONSTITUTION: For example, sand is charged by a hopper 8 into a mixer conveyor 1, and catalysts are put through a feed port 9. These are mixed and transferred by a screw feeder 3. The inside of the mixer 1 is encircled by a cooling jacket 13 and cooling dry air is sent through an inlet 11 for air etc., whereby it is cooled to ≤15°C. The cooled mixture is charged into a mixer 15; resin is added and mixed thereto through a feed port 20; the mixture is cooled and heat-insulated by a cooling jacket 23, and cooling dry air is fed through a inlet 21. Next, the mixture is discharged into a sand storage 25 having a cooling jacket and is supplied to a blow head 28 having a cooling jacket by a shutter 27. This tempering sand is blown into a metal mold 39 by way of a blow nozzle 29, whereby a mold and a core are obtained. Thereby, the hardening reaction of the tempering sand is suppressed and its pot life is considerably prolonged.
