Mold cooling method for characteristic analysis of lightweight material

The invention provides a mold cooling method for characteristic analysis of a lightweight material. By additionally installing a cooling system on a mold, and inputting cool air into the mold throughan air blowing cylinder, the portion with large feeding quantity and high heat-emitting speed of the mold is automatically cooled, so that the production efficiency is improved, and damage to the moldin the production process is reduced. The mold with the cooling system comprises an upper mold body, wherein a cooling insert is arranged on the upper mold body, and is inserted in the upper mold body, the air blowing cylinder is arranged at the front end of the cooling insert and is connected with an air cooler, and is connected with the cooling insert through a pipe joint, cold air blown out from the air cooler through the air blowing cylinder is conveyed to the cooling insert to cool the cooling insert, an automatic blocking valve is arranged in the pipe joint, and a temperature sensor isarranged on the upper mold
