PURPOSE: To provide a die temperature adjusting device to adjust the temperature of a die by making use of the metal of the low melting point which is lower than that of the molten metal in a cavity. CONSTITUTION: A cavity 25 to form a casting 3 is demarcated by an upper die 20 and a lower die 22 of a die 2. A temperature adjusting part 51 to form a low melting point metal chamber 51a in which the Zn-Al low melting point metal A (mark x) is charged is provided on the die part in the vicinity of a boss part 31 of a casting 3 in way of the lower die 22. A temperature adjusting part 52 to form a low melting point metal chamber 52a in which the Pb-Sb lower melting point metal B (mark○) is charged is provided on the part higher than the temperature adjusting part 51 in way of the lower die 22. Similarly, a temperature adjusting part 53 and a temperature adjusting part 54 are provided in way of the upper die 20.
