ABSTRACT:
The temperature of a casting die is controlled in a low-pressure casting process for pressurizing the surface of molten metal stored in a closed container to fill the molten metal in a die cavity defined in the casting die. The temperature of the casting die is detected by a temperature sensor, and compared with a preset reference die temperature range. The amount of cooling water to be supplied to the casting die is controlled based on the result of the comparison. When the detected temperature of the casting die falls in the preset reference die temperature range, the molten metal starts to be filled in the die cavity.
