Patent AT-E400378-T1: [Translated] MOLDING TOOL COOLING DEVICE

Published by National Center for Biotechnology Information (NCBI) | U.S. Department of Health & Human Services | Metadata Last Checked: September 07, 2025 | Last Modified: 2025-09-06
A mold cooling device includes an air feeding and discharging circuit 22 which effects the driving by air of a pump section 1 for feeding a cooling liquid to a fluid flaw passageway 65a fanned in a mold 64 and the feeding of air to the fluid flow passageway 65a. Letting (Dx) be the outer diameter-corresponding dimension of the holed convex portion 53x of a cast article 64x, (D1) be the outer diameter of the pin section 65 of the mold 64, (t1) be the outer peripheral thickness of the pin section 65, and (T1) be -5.103+(0.621xDx)-(1.068xD1)+(3.61xt1), the time (T) for feeding cooling liquid to the fluid flow passageway 65a after completion of the pouring of molten metal into the mold 64 is set so that the relation T1-0.5 seconds <=T<=T1x0.5 seconds is satisfied.
