The invention discloses an integrated molding extruder for rubber extrusion, relates to rubber molding equipment, and provides the integrated molding extruder for rubber extrusion with the function of decreasing moisture contained in a rubber raw material in the extruder during conveying. The main point of the technical scheme is that the integrated molding extruder comprises a plurality of fixed barrels and air suction barrels which are coaxially arranged, wherein the inner diameter of the air suction barrels is smaller than the inner diameter of the fixed barrels; the air suction barrels and the fixed barrels are arranged at intervals; air suction holes are formed in the upper ends of the air suction barrels; exhaust check blocks which cover the air suction holes are arranged on the air suction holes of the air suction barrels; and vacuumizing devices used for sucking water vapor in the air suction barrels are arranged on the exhaust check blocks.
