Abstract

The invention relates to the technical field of low-pressure casting, in particular to a mold for measuring internal cooling data of a low-pressure cast casting and an implementation method thereof.The mold comprises a mold body, a sampling end, a sensor mounting unit, a cooling mechanism and a controller, and the mold body comprises an upper mold base and a lower mold base which are oppositely arranged up and down; when the upper die base and the lower die base are closed, a cavity is defined and formed between the upper die base and the lower die base and used for containing molten aluminum to conduct casting, and a pouring cup used for allowing the molten aluminum to enter the cavity is arranged in the center of the lower die base. The temperature sensors mounted at different positions in the sensor mounting unit are used for comprehensively and finely monitoring the temperature change of the upper part, the middle part and the lower part of a casting sample in real time in the casting process, the temperature change in molten aluminum is accurately recorded, key data in the solidification process are collected, the temperature distribution uniformity in the cooling process is ensured, and the casting quality is improved. And internal defects and stress problems caused by non-uniform cooling are effectively prevented.
