The invention discloses a recoverable and reusable molding control mold core for hot isostatic pressing. The recoverable and reusable molding control mold core comprises a core body, a metal conducting layer and an isolating layer, wherein the core body is made of aluminum oxide ceramic, the metal conducting layer is made of Ag, and the isolating layer is made of Fe. The molding control mold core can be recovered and reused and is high in molding control accuracy, easily-corrosive material is adopted for isolating the mold core and parts, the isolating layer is corroded and removed after formation, the mold core and the parts are separated, and the molding control mold core can be recovered; material high in strength at high temperature is adopted for preparing the molding control mold core, and therefore deformation of the mold core is small at high temperature and high pressure, and the accuracy error of the formed parts is small relatively.
