Abstract
PURPOSE: To accelerate dehydration, increase the rate of hardening and shorten production time by blowing air into the core in the hot box core production process using the mixture of organic resin and sand.
CONSTITUTION: The mixed sand comprising compounding phenolic resin and sand is blown into a metal mold 1 which is heated and held at around 150W300°C, at the same instant of which air (ordinary temperature - about 250°C) is blown through the air inlet 3 of the metal mold 1. while the air is being exhausted through an air outlet 4, the resin is allowed to set, whereby the core 2 is formed. According to the abovementioned method, the core may be molded in a short time even by using the phenolic resin of less formalin compounding amount (or high-polymerized).
