The invention discloses a bearing platform type frame track plate die, which belongs to the technical field of the die for manufacturing railway ballastless track plates. The invention comprises a bottom die and side dies which can be connected at the front and rear two ends of the bottom die in a detachable way and end dies which can be connected at the right and left two ends of the bottom die in a detachable way. The side die and the end die can be connected with each other in a detachable way and the shape made up of the bottom die, the side die and the end die matches the external shape of the track plate; wherein, a plurality of installing holes for bolt are symmetrically arranged at the corresponding positions of the two sides of the bearing track part of the track plate and on thebottom die and a semi-circular protuberance is arranged at the middle part of the end die. A cupped bearing platform is arranged at the bearing track part corresponding to the installation holes for bolt on the bottom die and an internal die assembly which shapes the central part of the track plate into a frame structure is arranged in the middle of the bottom die. The bearing platform type frametrack plate die can satisfy the requirements for manufacturing the bearing platform type frame track plate for ballastless track.
