[0007] Specific implementation
[0008] Before mold development, perform casting simulation solidification first, find out the area of the mold that needs temperature field compensation, according to the casting simulation solidification result, this area is in the position of top mold 1 and side mold 2, install heating resistance wire at top mold 1 3. Top mold temperature measurement thermocouple 4, install heating resistance wire 5, side mold temperature measurement thermocouple 6 at side mold 2, and heat resistance wire 3, heating resistance wire 5, and top mold temperature measurement thermocouple 4. The mold temperature measuring thermocouple 6 is connected to the control cabinet 7 of the low pressure casting system, and the mold temperature is set according to the casting process process requirements. When the mold temperature reaches the process requirements, the heating resistance wire stops working; when the temperature is insufficient, the heating resistance wire start...
