The invention provides a supporting-plate-free brick making machine. The brick making machine comprises a first walking track, a second walking track, a material distribution vehicle arranged on the first walking track, a first driving mechanism for driving the material distribution vehicle to walk along the first walking track, a swinging material scraping mechanism arranged on the material distribution vehicle, a mold moving mechanism arranged on the second walking track, a brick forming mold frame arranged on the mold moving mechanism, a pressure head mechanism arranged on the mold moving mechanism and located above the brick forming mold frame, a second driving mechanism for driving the mold moving mechanism to walk along the second walking track, a vibration table mechanism arranged at a forming position, and a finished brick bracket arranged at a demolding position; the vibration table mechanism is provided with a supporting platform; and a movable material distribution frame isarranged on the material distribution vehicle, and the swinging material scraping mechanism is arranged on the movable material distribution frame. The supporting-plate-free brick making machine has the advantages that the formed brick transferring speed is high, and the overall brick making efficiency can be improved; and through the arrangement of the swinging material scraping mechanism, the pressing efficiency of the pressure head mechanism can be improved, and the yield of formed bricks can be increased.
