Title (EN) CASTING MOLD MANUFACTURING METHOD
(FR) PROCÉDÉ DE FABRICATION DE MOULE
(JA) 鋳型の製造方法
Abstract:
(EN) 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.
(FR) L'invention fournit un procédé de fabrication de moule selon lequel les propriétés de remplissage d'un sable à enduit et la résistance d'un moule sont améliorées, et une amélioration en termes d'usinabilité dans le domaine du façonnage, est obtenue de manière effective. En outre, l'invention fournit un procédé ne nécessitant pas une nouvelle installation de dispositifs particuliers, et permettant de fabriquer de manière avantageuse le moule souhaité avec un dispositif pour façonnage de l'art antérieur tel quel. Un milieu aqueux comprenant un tensio-actif et/ou un polyol, est ajouté au sable à enduit à l'état sec obtenu par revêtement de la surface d'un agrégat ignifuge au moyen d'un liant hydrosoluble, et après humidification, le sable à enduit à l'état sec ainsi obtenu remplit une matrice, et le moule souhaité est ainsi façonné.
(JA) コーテッドサンドの充填性や鋳型の強度を向上させつつ、造型現場での作業性の改善を効果的に図り得る鋳型の製造方法を提供する。また、特別な装置を新たに設置する必要なく、従来の造型のための装置をそのまま用いて、目的とする鋳型を有利に製造することの出来る方法を提供する。 耐火性骨材の表面を水溶性バインダにて被覆して得られる乾態のコーテッドサンドに、界面活性剤及び/又は多価アルコールを含有せしめてなる水性媒体を添加して、湿態化させた後、その得られた湿態化コーテッドサンドを成形型に充填して、目的とする鋳型を造型する。
