The invention relates to a sliding block drag hook mechanism which comprises a fixed die, a lateral cavity and a lateral push sliding block. A drag hook device and a drag hook bearing plate are arranged between the lateral push sliding block and the lateral cavity, the lateral push sliding block is provided with a drag hook accommodating cavity used for accommodating the action of the drag hook device, the bottom side of the lateral cavity is provided with a hook groove, the drag hook device comprises two hook claws bent outwards, the positions close to front ends of the two hook claws are connected with a spring, fixing shafts penetrate through the tail ends of the hook claws, a sliding groove is formed in the drag hook bearing plate, the bottom ends of the fixing shafts of the hook clawsof the drag hook device are provided with a sliding base, the tail end of the sliding groove is opened, the front end of the sliding groove is closed, and the closed end forms front limiting of the sliding base. The sliding block drag hook mechanism achieves a fixing and guiding effect, part production of two or more work procedures can be integrated into a whole, human resources and the workingcost are saved, the machining progress and precision of parts are kept, the product rejection rate is reduced, and therefore the production rate is improved.
