Title:
CASTING MOLD MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/043412
Kind Code:
A1
Abstract:
Provided is a casting mold manufacturing method that is capable of effectively improving workability at a molding site while improving coated sand fillability and casting mold strength. Provided is a method that is capable of advantageously manufacturing an intended casting mold by using a conventional molding device as is without any need to newly install a special device. The intended casing mold is formed by adding an aqueous medium prepared by including a surfactant and/or a polyhydric alcohol in dry-state coated sand obtained by covering the surface of a refractory aggregate with a water-soluble binder, moistening the coated sand, and then filling a molding die with the obtained moist coated sand.
