Mold temperature control device and mold temperature control method

摘要

PROBLEM TO BE SOLVED: To provide a device and a method for mold temperature adjustment which can reduce deposition of scale in a conduit line through which a cooling medium for cooling a temperature adjustment medium flows.SOLUTION: A mold temperature adjustment device 1 supplies a temperature adjustment medium to a medium passage 4 provided in a mold 3 in a circulating manner and includes a heat exchanger 30 which has a cooling path 32 always causing the cooling medium to flow through in a stationary operation state of the mold temperature adjustment device and a medium path 31 causing the temperature medium heat-exchanged indirectly by the cooling path to flow through and a control part 34 making the medium path to conduct a control of flowing the temperature adjustment medium in cooling the temperature adjustment medium.SELECTED DRAWING: Figure 1
