The invention discloses a station reversing mechanism for a molding mold of an automotive sound-proof felt automatic mounding machine, and belongs to machinery for molding automobile interior parts. The moulding mould comprises a mould body and rolling devices which are arranged at four corners of the bottom surface of the mould body. The station reversing mechanism comprises a rail assembly which consists of a group of longitudinal guide rails and a group of transverse guide rails, wherein the longitudinal guide rails are parallel to each other longitudinally; and the transverse guide rails have the same number as the longitudinal guide rails and are parallel to each other transversely. Each transverse guide rail and each longitudinal guide rail form a perpendicular cross relation. A mould rail-changing rotation device is arranged at the intersection of each transverse guide rail and each longitudinal guide rail and is used for running through the longitudinal guide rail and the transverse guide rail so as to change the motion direction of the rolling devices together with the mould body. A reversing execution device used for driving the rail-changing rotation device to move is connected to each rail-changing rotation device. The station reversing mechanism for the moulding mould of the automotive sound-proof felt automatic moulding machine can meet the modularization requirement on the automotive sound-proof felt automatic moulding machine.
