The utility model discloses a multifunctional experimental mold, which is characterized by also comprising a punching mold die with a first through hole, wherein the first through hole is used for allowing a forming mold die to pass through, the upper end of the punching mold die is a punch, a retaining plate is arranged above the punch, a second through hole which is used for the punch to pass through is arranged on the retaining plate, a punching mold female die is arranged above the retaining plate, the punching mold female die is provided with a third through hole which is used for the punch to pass through, a concave surface of the punching mold female die is tightly matched with a convex surface of a forming mold female die, a sampling hole, a forming hole, the third through hole, the second through hole and the first through hole are coaxial, and the diameter of the forming hole is greater than that of the first through hole and smaller than that of the sampling hole. The punching and the forming are integrated to be completed through a continuous action, so that the experimental period is shortened, the centering alignment problem of a wafer specimen in a forming experimental process can be avoided, the experimental detection efficiency and accuracy can be improved, and the experimental cost can be reduced.
