Cooling mechanism for injection mold

The utility model belongs to the technical field of injection molds, and particularly relates to a cooling mechanism for an injection mold. A vertical frame is fixedly connected to the top face of the supporting table, an air cylinder is fixedly installed at the middle end of the top face of the vertical frame, and an upper mold is connected to the bottom end of the air cylinder. The buffering device is arranged at the middle end of the top of the supporting table; a first toothed plate is arranged to descend, then a connecting plate compresses a damper and a spring on the outer surface of the damper, and therefore the buffering function is preliminarily achieved, and a second toothed plate is arranged to ascend, so that the second toothed plate drives a mounting plate and a connecting frame to ascend; according to the scheme, multiple buffering is arranged, so that the impact force borne by the sleeve block and the lower die is greatly reduced, and the probability that the lower die is damaged is reduced. 本实
