The invention discloses a soldering production device for a terminal socket. The soldering production device comprises an upper barrel and a lower barrel; the lower end of the upper barrel is in threaded connection with the upper end of the lower barrel; a heating wire is electrically installed at the lower end of the lower barrel; and a supporting frame is fixedly installed on the side wall of the upper barrel, the upper end of a push rod is slidably clamped into the supporting frame, and the lower end of the push rod is fixedly connected with the upper end of a piston. According to the soldering production device, before soldering is started, a solder stick is put into the lower barrel, the upper barrel is made to be in threaded connection with the lower barrel, the heating wire is started for heating so that the solder stick can be melted, an extrusion rod is pressed, after the lower end of the extrusion rod pushes a gear to rotate by a grid, the extrusion rod is returned back to the original position under the elastic force of a spring, the gear is rotated by one grid, then, a gear plate structure on the push rod slides downwards by a grid, when the push rod needs to go back tothe original position, the extrusion rod is lifted up, and the gear is reversely pulled.
