The invention discloses an ejector rob and gasket combined type metal creep forming die. The ejector rob and gasket combined type metal creep forming die comprises ejector robs, gaskets, an ejector rob fixing plate and a molded surface cushion plate; the ejector robs have the same height, and the gaskets have the same thickness; each ejector rob comprises a rob body, and an end head with a screw; a threaded hole which is matched with each screw is arranged in each rob body; orthogonal grooves which are crisscross arranged in transverse and longitudinal directions are formed in the ejector rob fixing plate surfaces; the ejector rob bodies are mounted at the crisscross arranging parts of the orthogonal grooves; the gasket is arranged in the orthogonal grooves and below the ejector rob bodies; the gaskets are overlapped in different thickness, the height of the ejector robs is roughly adjusted and then is accurately adjusted through the screws at the end heads of the ejector robs, so as to form an ejector rob array as requirement. The die is simple to manufacture and convenient to operate; the large tool creep forming engineering experiment research and small batch production apply; with the adoption of the die, the problems caused by the processing cost and research and development cycle due to the repeated die modification in the experiment can be avoided; in addition, the degree of wave on the surface of a forming part is less than 0.5%.
