Title:
MOLD COOLING DEVICE, CAST PRODUCT MANUFACTURING SYSTEM, AND CAST PRODUCT MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/185358
Kind Code:
A1
Abstract:
A cooling device (21) comprises radiation temperature meters (51-55), a plurality of nozzle parts, a plurality of electromagnetic valves (V1-V5), and a control device (60). The radiation temperature meters respectively detect, at a plurality of parts of a mold, pre-cooling temperatures which are the temperatures before the plurality of nozzle parts spray the mold with cooling water. On the basis of the deviations between the respective pre-cooling temperatures of the plurality of parts of the mold and corresponding target temperatures, the control device individually sets cooling times for the plurality of parts of the mold. The control device controls the electromagnetic valves on the basis of the respective cooling times which are individually set for the plurality of parts of the mold.
