The invention provides a method for testing the corresponding relation between the temperature at a sand mold casting temperature measuring hole and the actual temperature, which comprises the following steps of: manufacturing a sand mold according to experimental equipment and materials, embedding a thermocouple when the sand mold is manufactured, and rolling the temperature measuring hole at a position close to the embedding position by adopting a steel needle; thermocouples are inserted into the temperature measuring holes, the inserted thermocouples and the embedded thermocouples are electrically connected with a temperature recorder, and the temperature recorder is started; molten metal pouring is conducted on the sand mold, and the temperature recorder records the temperature of the thermocouples inserted into the temperature measuring holes and the temperature of the embedded thermocouples in real time; one of the four parameters of the pouring temperature of molten metal, the distance between the embe
