Title: Reduce pressure casting method and moulding apparatus
Inventor: LEE DONG-SHIK
IPC: B22D18/06
Filed: 1982-05-13
Granted: 1984-09-26
Abstract: During high temperature melting-bath injection, the air exit of a melting box is connected with a vacuum pump to reduce the internal pressure to 40-60 CmHg. The injection of the melting bath is performed under vacuum-reducing pressure, thus directly burning the model, preceded by ventilating, which is characteristic of casting. The above-mentioned molding box is made up of square-shaped, ellipse and circular shaped metallic packed vessel. The primary characteristic of this method is that vacuum-reducing pressure can occur by connecting the inner side of the molding box to the vacuum pump.
