Extrusion shaping machine used for shaping multi-cavity profiled bars

The utility model discloses an extrusion shaping machine used for shaping multi-cavity profiled bars. The extrusion shaping machine comprises an extruding machine, an extruding die head, a shaping die, a water tank, a shaping table, a traction machine and a crawler belt, wherein the extruding die head comprises an opening die plate, a prefabricated plate, a compression plate, a support core, a transition plate, a support sprue spreader and a machine neck which are sequentially and fixedly connected, the transition plate is fixedly connected with an air blowing connector, the opening die plate is provided with air blowing holes, the air blowing holes are connected with the air blowing connector through air grooves, and the opening die plate, the prefabricated plate, the compression plate, the support core and the transition plate are each provided with one air groove and communicated with one another. According to the extrusion shaping machine, the air blowing connector is designed on the die head transition plate, air blowing is performed through the die head outlet end, it is forced that before the profiled bars enter the shaping die, inner ribs can be fully cooled and shaped, cooling stress of parisons in the shaping die is eliminated, bending adhesion of the inner ribs is avoided, flatness and straightness and shape and dimension precision of the inner ribs of the profiled bars are guaranteed, design defects are compensated for, and the adaptive capacity for an extrusion process is enhanced.
