The invention discloses a hydraulic excitation vibrating brick press. The hydraulic excitation vibrating brick press comprises a plunger exciter; the plunger exciter is connected with the tail of a hydraulic cylinder; the hydraulic cylinder is arranged in an opening in an upper crossbeam; the upper crossbeam, a slider and a base form a 'three-beam four-post' press structure through four guide posts; a split flange is clamped in a groove in a piston rod of a piston and is connected with the upper part of the slider; an upper pressure head is fixed to the lower surface of the slider; a molding box is fixed to the upper surface of the base; the hydraulic excitation vibrating brick press adopts the 'three-beam four-post' press structure integrally, main forming force is generated by the piston, an alternating-current servomotor drives an end cam to further drive an excitation plunger to generate excitation force, and the two processes are matched to drive the upper pressure head to perform hydraulic compaction and vibration forming on powder; the hydraulic excitation is realized in a mode of additionally arranging the excitation plunger at an oil cylinder, so that the brick press has good vibration forming performance.
