For achieving the above object; The utility model comprises co-extrusion die holder, die holder, rebound, cylinder manifold, mouthful mould, water jacket, tail water cover; The co-extrusion die holder is fastenedly connected through screw I and die holder; Screw III connects die holder, rebound, cylinder manifold and mouthful mould successively, and screw II connects mouth mould, water sleeve tail water cover successively, also comprises being loaded on the guider in the die holder endoporus and being loaded on the supporting plate on the die holder right side; Guider is connected with supporting plate through screw IV, and supporting plate is connected with die holder through screw IV; The outer surface of said co-extrusion die holder is provided with screw thread, is provided with hole I at the center of co-extrusion die holder; Said die holder is provided with inclined hole, is provided with hole II at the center of die holder; There is a convexity at the middle part of said guider, and a male cone (strobilus masculinus) is arranged on the outer surface of the left side of guider, is provided with hole III at the center of guider; The center of said rebound is provided with hole IV; The center of said cylinder manifold is provided with internal taper hole; Said water sleeve tail water puts and is equipped with cooling water hole; Said mouthful of mould, water jacket and the center of tail water cover are equipped with the hole V of identical size; Adopt matched in clearance between the outer surface of said guider and the endoporus of die holder.

The utility model is owing to be provided with hole I at the center of co-extrusion die holder, the center of die holder is provided with inclined hole identical with co-extrusion die holder diameter, dead in line, and the center of rebound is provided with hole IV; The center of cylinder manifold is provided with internal taper hole; There is a convexity at the middle part of guider, a male cone (strobilus masculinus) is arranged, like this on the outer surface of the left side of guider; Between co-extrusion die holder, guider, die holder, rebound and cylinder manifold, form a radwood runner; Be provided with hole III at the center of guider, be convenient to steel core and pass, thereby realize wooden plastic-steel core co-extrusion.Through on probation, this utility model is rational in infrastructure, and co-extrusion is effective, and production efficiency is high, is easy to make, and cost is low, long service life.

Description of drawings:

Fig. 1 is the overall structure sketch map of the utility model.

The specific embodiment:

Referring to Fig. 1; The utility model comprises co-extrusion die holder 1, die holder 13, rebound 3, cylinder manifold 4, mouthful mould 5, water jacket 6, tail water cover 7; Co-extrusion die holder 1 is fastenedly connected through screw I and die holder 13; Screw III connects die holder 13, rebound 3, cylinder manifold 4 and mouthful mould 5 successively, and screw II connects mouth mould 5, water jacket 6 and tail water cover 7 successively, also comprises being loaded on the guider 14 in die holder 13 endoporus and being loaded on the supporting plate 16 on die holder 13 right sides; Guider 14 is connected with supporting plate 16 through screw IV, and supporting plate 16 is connected with die holder 13 through screw IV.The outer surface of said co-extrusion die holder 1 is provided with screw thread 1a, is provided with hole I 1b at the center of co-extrusion die holder 1.Said die holder 13 is provided with inclined hole 13b, is provided with hole II 13a at the center of die holder 13.There is a protruding 14a at the middle part of said guider 14, and a male cone (strobilus masculinus) 14c is arranged on the outer surface of the left side of guider 14, is provided with hole III14b at the center of guider 14.The center of said rebound 3 is provided with hole IV3a.The center of said cylinder manifold 4 is provided with internal taper hole 4a.Be equipped with cooling water hole 11 on said water jacket 6 and the tail water cover 7.Said mouthful of mould 5, water jacket 6 and the center of tail water cover 7 are equipped with the hole V 17 of identical size.Adopt matched in clearance between the endoporus of the outer surface of said guider 14 and die holder 13.

During work, co-extrusion die holder 1 is connected with extruder through screw thread 1a, and the radwood fluid flows out from extruder; Get among the hole I at co-extrusion die holder 1 center, get into the inclined hole 13b of die holder 13 then, flow to again in the cavity that forms between guider 14 and die holder 13, rebound 3, cylinder manifold 4 and mouthful mould 5; When the radwood fluid flow to the cavity between the hole IV at protruding 14a and rebound 3 centers of guider 14, the radwood fluid produced turbulent flow, to redistribute the radwood fluid; When the radwood fluid flow to the cavity between the internal taper hole 4a at male cone (strobilus masculinus) 14c and cylinder manifold 4 centers of guider 14, because this regional runner is by wide gradually narrow, the radwood fluid will produce compression; To improve the density of radwood fluid, when the radwood fluid flows out the hole V at cylinder manifold 3 inlet port moulds 5 centers, because of when the mold work; Steel core 10 is through the hole III guiding at guider 14 centers, gets into and sends to let continuous from the right of the hole III at guider 14 centers, and this moment, steel core 10 was among the hole V at mouthful mould 5 centers; The radwood fluid will be compounded on the outer surface of steel core 10, and in mouth mould 5, be shaped, and form wood and mould layer 9; When wood is moulded layer 9 and is got into water jackets 6 and overlap 7 with tail water, will cool off gradually through cooling water hole 11, make wood mould layers 9 and formalize; This process is carried out continuously, has just formed wooden plastic-steel core decoration materials.
