The invention discloses a high-efficiency model test standard test-piece processing mold and a use method thereof. The high-efficiency model test standard test-piece processing mold comprises a pressure-bearing mold-forming structure, a solid mold constraining structure and a force component mold pressing structure, wherein the pressure-bearing mold-forming structure comprises molds, mobile type clamping boards, bases and pulling trays; a large clamping board and a small clamping board of each mobile type clamping board are respectively embedded in each mold and in fit connection with large fan-shaped grooves and small fan-shaped grooves in each base; hooks of each pulling tray can be buckled to nose rings at the upper end surface of each large clamping board; the solid mold constraining structure comprises a groove cylinder and bolts; the molds are sleeved in grooves of the groove cylinder, and the molds are fixed by screwing the bolts; the force component mold pressing structure comprises force bearing beams, universal ball bearing grooves, universal balls and a pad pressing column, wherein the force bearing beams are connected with the pad pressing column by the universal ballshinged in the universal ball bearing grooves; according to the invention, a non-integrated mold is adopted, the adhesion between a test piece and the molds is effectively reduced, the removal is facilitated, and four test pieces can be suppressed at the same time, so that the efficiency of the test piece production is greatly improved, and demoulding is facilitated.
