[0037] In operation, the guide wheel 5 and the support wheel 6 apply tension in the vertical direction to the cable core and the cable semi-finished product, preventing the cable core from bending and shaking when passing through the mold core 3, thereby reducing the possibility of the cable core contacting the inner wall of the mold core 3. In addition, the inner diameter of the supporting area 4 in the mold core 3 gradually expands along the moving direction of the cable core, which can effectively prevent the cable core from being scratched by the inner wall of the mold core 3, thereby reducing the phenomenon of poor plasticization of the extruded layer caused by heat loss due to scratching, and preventing the mold from being scratched from the structural design. Finally, the quality stability of the molding device in the production of cable semi-finished products is effectively improved, the rework rate and material waste caused by the phenomenon of scratching are significantly reduced, thereby reducing economic losses, improving production efficiency, and ensuring timely delivery.
