Sheath extrusion molding device for processing heat-resistant shielding cable

The utility model relates to the technical field of cable sheath processing, in particular to a sheath extrusion molding device for processing a heat-resistant shielding cable, which comprises a base, an extruder is fixed on the upper surface of the base, and a feeding box is fixed at the top end of one side of the extruder; the vibrating screen mechanism is arranged, the vibrating motor serves as a power source to be matched with the spring to enable the two screen plates to vibrate, raw materials with overlarge sizes are discharged along with vibration in the vibrating process, and the situation that finished products are scrapped due to the fact that the overlarge raw materials cannot be completely melted in the subsequent hot melting process is avoided; raw materials conforming to specifications fall into the bottom of the discharging box and enter the stirring box to be stirred and mixed; a first motor is used as a power source to drive a driving gear and a driven gear to rotate, three shafts rotate to d
