摘要:PURPOSE:To sufficiently cool and heat a die with simple structure and to maintain the die temp. at optimum temp. always by returning to a feed water pump one part of the drain which cooled a die with pump feed water by controlling an adjusting valve by actuating with drain temp. CONSTITUTION:The drain flowed out to the piping 10 at discharge side by flowing the cooling paths 2a, 2b, 2c of a die by a feed water pump 9 via piping 8 from a cooling water feed source 7 is discharged by an adjusting valve 11. In that case, the adjusting valve 11 is controlled by a drain measuring temp. signal 12 to return one part of the drain to the feed water piping 8 for the feed water pump 9 via the piping 14 having a check valve 15. The drain temp. inside the discharging side piping 10 is freely controlled high and low to maintain a die 1 at specific temp. or optimum temp. at all times with a simple structure.
