<P>PROBLEM TO BE SOLVED: To provide a casting die that has a simple configuration for easily and reliably controlling the temperature thereof at a uniform level. <P>SOLUTION: The casting die 1 includes a heating medium path 30 for circulating a heating medium from a portion that reaches a high temperature TH relative to the process of casting to a portion that reaches a low temperature TL relative to the process of casting. An inlet 30a of the heating medium path 30 through which the heating medium is introduced is provided on a side 12 close to a hot water opening, and an exit 30b is provided on a side 13 opposite to the hot water opening. A temperature control hole 31A formed at an end of the casting die providing the inlet 30a of the heating medium path 30 communicates with an outlet of a cooling circuit 15a to which a cooling medium for a spool bush 15 is supplied. The heating medium path 30 is formed to serve as communication between a plurality of temperature control holes 31, 31, ... provided in the casting die 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
