Abstract

PURPOSE: To improve productivity by mixing limited weight of water-soluble paste and water with silica sand, filling up the cavity of upper and lower core boxes with the mixture and irradiating microwave after removing the top part, and thereby hardening it quickly evaporating moisture from the upper part.
CONSTITUTION: A cavity 7 of horizontally divided top and bottom core boxes 1, 6 is filled up with mixed sand prepared by mixing 1W5pts.wt. water-soluble paste to 100pts.wt. silica sand and 50W100pts.wt. water to the water-soluble paste. The bottom part core box 1 is then lowered, and the filled material is taken out with it placed on the core box 1. When the filled material is irradiated by high frequency wave or microwave, the unhardened core having open upper part on the bottom part core 1 is heated by induction and moisture is removed from the upper part by quick evaporation and dried and hardened.
