[0025] By adopting the technical scheme, the thermocouple is used to record the temperature change value of the alloy liquid in the thick branch cavity, thereby obtaining the dynamic change relationship between the alloy stress value and the temperature, and since the alloy liquid in the thick branch cavity is the last to solidify, detecting the temperature in the thick branch cavity as the reference of the dynamic change relationship between the stress value and the temperature is more accurate.

[0026] The utility model has the advantages of:

[0027] 1.
