Hydraulic stripper machine

The invention provides a hydraulic demolding machine, and relates to the field of demolding equipment, the hydraulic demolding machine comprises a plurality of workpiece lifting vehicles, the plurality of workpiece lifting vehicles are slidably arranged in a mounting cavity, and the plurality of workpiece lifting vehicles are used for supporting a to-be-demolded mold and a demolded mold core; the heavy frame comprises a limiting frame and two stress columns, the limiting frame is used for limiting the mold during demolding, and the limiting frame is installed on the foundation; and the tractor comprises a driving seat, a traction head and two hydraulic cylinders. According to the hydraulic demolding machine, the hydraulic cylinder with the limited stroke is matched with the multiple force transmission devices to pull out the mold core from the mold section by section, demolding is completed, and the occupied area is greatly reduced; the puller principle is adopted, demolding force is changed into internal for
