The utility model provides a slope hydraulic pressure self-propelled hidden rail dragging mould which comprises traveling beams, a balance beam, a template system, a work platform and a hydraulic pressure system. Each traveling beam comprises a cross beam, a front sliding seat, a rear sliding seat, an adjusting screw rod and an oil cylinder seat. The front sliding seats are connected with the cross beams in a rigid mode. The rear sliding seats and the cross beams are hinged. The template system comprises a template, a bearing beam and a template system supporting frame. The bearing beam and the balance beam are arranged in parallel. The traveling beams are respectively arranged at two ends under the bearing beam and the balance beam along the perpendicular direction. The template system supporting frame is arranged at rear end of the template. The work platform is parallel to a guide rail and is cable-stayed on the template system supporting frame through a spiral locking device. The hydraulic system mainly comprises a hydraulic pressure pump station, advancing oil cylinders, a hydraulic pressure pipeline and the like. The hydraulic pressure pump station is arranged in the middle of the bearing beams. The advancing oil cylinders are arranged below the two traveling beams. The dragging mould is free from limitation of a slope, can carry out continuous pouring of concrete in a large quantity and large area mode, and is fast in pouring speed and good in quality.
