In the production of automobile parts, aluminum parts are used as important links in the light weight and energy saving technology of automobile chassis, and currently surpass iron parts and become key parts of mainstream automobile configuration. Compared with iron parts, the casting temperature of aluminum parts is low, defects are easy to generate in the casting process, and the aluminum parts are poor in toughness, easy to deform and poor in hardness, so that the requirements on the casting process are more severe, and the temperature control requirement on castings in the casting process is more urgent, and therefore, the die casting machine equipment with the die temperature adjusting capability is very necessary.

However, as the change condition of the mold temperature in the casting process cannot be directly observed manually, only manual evaluation can be performed on the casting process according to the internal quality condition of the finished cast product, and the casting condition is judged in a mode that the temperature of the mold cavity surface is collected through a thermal camera, but the mold and air heat exchange condition is complex, the collected time point is different, the temperature data can be changed, the change condition of the mold temperature in the whole casting process cannot be completely reduced only by depending on the mold cavity temperature condition of one time point, and the existing die casting machine equipment does not have the capability of adjusting the mold temperature in the casting process. Under the condition that the temperature of the die cannot be visually represented and can not be automatically regulated in the casting process, the casting process can be adjusted manually only by experience subjectively, and the conditions of long adjustment time and increased waste are easily caused.
It follows that there is a problem in the prior art that the autonomous regulation of the mold temperature during casting cannot be effectively performed.
