The invention discloses an unconfined compressive strength part and a demolding and strength measuring integrated testing machine which can be used for finishing high-efficiency and high-quality test detection operation. The testing machine comprises fixing nuts, an upper bearing plate, upright posts, clamping parts, jackscrews, a frame, a lower bearing plate, a motor, a lifting jack, rails, a data line, a pressure sensor, a hydraulic pipe, a test mold, an annular stirrup, an adjusting screw rod, vehicle panel fixing fasteners, a round plate with an annular groove, a sliding trolley panel, wheels, axles, clamping plates and clamping plate slideways. According to the design of the double upright posts, the overall weight is reduced; bottom feet are designed on the lower bearing plate, and thus stress deformation of the lower bearing plate is avoided; due to the design of the clamping parts with a jackscrews and the annular stirrup added to the test mold, a novel mode of simple and feasible demolding is created. According to the invention, the various parts can be convenient to detach and assemble, the equipment performance is stable, the operation is simple, labor force is saved, the labor intensity is reduced, and the working efficiency is improved.
