Automatic discharging device

The utility model relates to the technical field of lens injection molding machines, in particular to an automatic blanking device which comprises two guide columns, a rack and a blanking mechanism, the blanking mechanism comprises two springs, an abutting plate, two fixing boxes and a receiving disc, the two springs abut against the corresponding fixing boxes respectively, the two springs abut against the abutting plate respectively, and the receiving disc is arranged on the rack. The abutting plates are slidably connected with the corresponding fixing boxes, the two fixing boxes are fixedly connected with the conveying belt, the receiving disc is fixedly connected with the rack, a mold is ejected out of the position between the two fixing clamps through the abutting plates, the mold enters the receiving disc to be cooled, and the problem that due to the fact that the temperature of the mold subjected to injection molding is high, the mold cannot be cooled is effectively solved. And an automatic discharging
