▎ 摘　　要

NOVELTY - The metal mold has a temperature measuring device that is arranged in a left mold (6) and a right mold (5). A heating module and a cooling module (7) are arranged outside the left mold and the right mold. A visual controller (9) is connected to the temperature measuring device. The heating module and the cooling module display the data of the three and controlling the actions of the three. A cavity (14) is formed in the left mold and the right mold. The temperature measuring device is used to measure the temperature in the mold cavity. The cooling module and the heating module are laid on the outer surface of the left mold and the right mold for cooling and preheating the left mold and the right mold according to the measurement data of the temperature measuring device. A super heat conducting layer is made of graphene material. USE - Metal mold. ADVANTAGE - The temperature measuring device and the cooling module, the crystal grains of the cast workpiece are smaller, the components and the tissues are more uniform in addition, the automation is high, the visualization degree is high, and the defects of the workpiece are obviously reduced. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the metal mold. Right mold (5) Left mold (6) Cooling module (7) Visual controller (9) Cavity (14)
