The invention discloses a C type concrete brick model production device. The device comprises a pedestal and a steel plate platform arranged on the pedestal, the steel plate platform is provided witha brick model die facilitating assembling and disassembling and a fixing device used for fixing the brick model die, multiple reinforcing steel bar frames for producing C type concrete brick models are placed in the brick model die, C openings of the reinforcing steel bar frames face downward, and an eccentric vibration machine for vibrating the brick model die is arranged below the steel plate platform. A process for using the device is provided. Production of multiple brick models at a time is achieved, due to the fact that the openings face downward, compared with opening upward or openinglateral placement, concrete on the side faces of the brick models is directly filled in the vertical direction due to the gravity effect, the direction does not need to be changed, top face direct casting is carried out, concrete filling can be rapidly finished, the problem that the flowing speed of concrete is low, and production efficiency is low is solved, and the condition is created for pouring of a secondary structure constructional column.
