The invention discloses an operation method of a cooling device for a mold core for preventing shrinkage pits, and relates to the field of mold manufacturing. The cooling device comprises a supportingframe, a pushing air cylinder, a supporting rod, a left grinding tool, a clamping structure, a pushing structure, an upper mold core, a right mold, a lower mold core, a cooling pipe and an air inletfan. A spray head is pushed to the positions of the left grinding tool and the right mold through the pushing structure, the upper mold core and the lower mold core are cooled through air injection ofthe spray head, the forming process is improved when insulators with uneven wall thicknesses and extremely deep inner holes are made; a blowing cooling device is additionally arranged on a forming process manipulator, and an injection molding machine is controlled to produce in large-scale production by writing an output program. A series of process procedures such as automatic product taking, automatic hole-by-hole air bl
