[0055] See Figure 1~Figure 16 , The present invention uses an extrusion method to manufacture a mold with ribs in the middle of the inner and outer double pipes. It is characterized in that it comprises a convex mold 2 and a concave mold 7 arranged coaxially up and down. The top of the convex mold 2 is fixed on the upper mold plate 1. Next, the female mold 7 is fixed on the upper surface of the lower mold plate 11, and the ejector rod 12 is slidably installed in the through hole in the middle of the lower mold plate 11.
[0056] An inner tube forming groove 23 is provided in the middle of the bottom end of the convex mold, a plurality of radial rib forming grooves 24 are provided on the outer periphery of the inner tube forming groove 23, and outer peripheral protrusions are provided on both sides of the rib forming groove 24 The die head 21, in the inner tube forming groove 23, is a central convex die head 22 corresponding to the bottom of the inner tube.
[0057] The bottom end...
