The invention discloses a gear pump-type continuous rubber injection device. The gear pump-type continuous rubber injection device comprises a Y-shaped extruder, a guide rail and a mould; the discharge end of the Y-shaped extruder is connected with a screen changing filter device; the screen changing filter device is connected with a gear pump; the gear pump is connected with the mould by a nozzle; the Y-shaped extruder is arranged on the guide rail through a first mounting seat; and the screen changing filter device and the gear pump are arranged on the guide rail through a second mounting seat. Rubber can be infinitely extruded out; meanwhile, by twice pressurization of an extruding unit and the gear pump unit, extremely high injection pressure can be given to the rubber, so that the rubber can be full of a mould cavity more efficiently; and quality of the rubber can be effectively increased by the filter device, so that the complete device is extremely suitable for large-sized injection rubber products, an
