COOLING WATER CIRCULATING APPARATUS FOR METALLIC MOLD

摘要

PROBLEM TO BE SOLVED: To provide a cooling water circulating apparatus for metallic mold with which clogging and constriction of a cooling water pipe line do not occur and the consumption of the cooling water can drastically be reduced.;SOLUTION: A water cooling device 20 for cooling the inside of the metallic mold 10 and a cooling device 30 for cooling high temperature water after cooling the metallic mold are connected through a relief valve 23 controlled according to a forming action, and a temperature adjusting device 40 for adjusting the temperature of the cooled cooling water is connected to the cooling device 30. Further, a water-treating device 50 for removing mineral component and scale, etc., contained in the cooling water is connected to the temperature adjusting device 40, and thus environmental load can be reduced by reducing the consumption of the cooling water at the formation with the metallic mold, and components for clogging and plugging the cooling water line for metallic mold 10 can be removed from the cooling water and the occurrence of a defective formed product can be reduced.;COPYRIGHT: (C)2005,JPO&NCIPI
