Description
Technical field:
The utility model relates to mould of plastics, and specifically a kind of wood is moulded the coating co-extruding mould.
Background technology:
The single wood that the product that existing wood type of moulding decoration materials die production is come out is made up of polyethylene is moulded a layer structure, because poly intensity is not high, bearing capacity is less; Frangible, and fire resistance is poor, and fire-protection rating is low; Security performance is relatively poor, and these factors directly influence its scope of application, in the occasion especially high at desired strength, that bearing capacity is big, fire-protection rating is had relatively high expectations; Owing to can not get safety assurance, can't use this wood type of moulding decoration materials.
The utility model content:
The purpose of the utility model with regard to provide a kind of rational in infrastructure, co-extrusion is effective, production efficiency is high, be easy to make, cost is low, the wood of long service life is moulded the coating co-extruding mould.
For achieving the above object; The utility model wood is moulded the coating co-extruding mould and is comprised die holder, rebound, fore-stock plate, after-poppet plate, cylinder manifold, mouthful mould, water jacket, tail water cover; Screw I connects die holder, rebound, fore-stock plate, after-poppet plate and cylinder manifold successively; Screw II connects mouth mould, water sleeve tail water cover successively; Also comprise being loaded on the fore-stock in the fore-stock plate endoporus and being loaded on the after-poppet in the after-poppet plate endoporus, be provided with preceding plug in the said fore-stock, be provided with the back plug in the said after-poppet; The outer surface of said die holder is provided with screw thread, is provided with hole I at the center of die holder; The right of plug is a wedge-type shape before said; The center of said rebound is provided with hole II; The center of said cylinder manifold is provided with the tail cone hole; Said water sleeve tail water puts and is equipped with cooling water hole; The center of said mouth mould, water sleeve tail water cover is equipped with the hole III of identical size; The center of said back plug is provided with interior cooling water hole; The right side of said mouthful of mould is provided with groove.
The utility model is provided with hole I owing to having adopted at the center of die holder; The center of rebound is provided with hole II, and the center of cylinder manifold is provided with the tail cone hole, and the right-hand member of preceding plug is wedge shape; Like this, between die holder, rebound, fore-stock, after-poppet and cylinder manifold, form wood and mould the laminar flow road; Owing on the right side of mouth mould, be provided with groove, this groove is the clad runner, coat material and just from this groove, flow into, and the hole on the left side, cylinder manifold 8 center is less than the hole at mouth mould 9 centers, will mould that coextru-lamination goes out clad on the layer at wood.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;
Fig. 2 is the I place enlarged drawing of Fig. 1.
The specific embodiment:
Referring to Fig. 1 to Fig. 2; The utility model comprises die holder 1, rebound 3, fore-stock plate 5, after-poppet plate 6, cylinder manifold 8, mouthful mould 9, water jacket 10, tail water cover 11; Screw I connects die holder 1, rebound 3, fore-stock plate 5, after-poppet plate 6 and cylinder manifold 8 successively; Screw II connects mouth mould 9, water jacket 10 and tail water cover 11 successively; Comprise also being loaded on the fore-stock 4 in fore-stock plate 5 endoporus and being loaded on the after-poppet 7 in after-poppet plate 6 endoporus that plug 4a before being provided with in the said fore-stock 4 is provided with back plug 7a in the said after-poppet 7.The outer surface of said die holder 1 is provided with screw thread 1a, is provided with hole I at the center of die holder 1.The right of plug 4a is a wedge-type shape before said.The center of said rebound 3 is provided with hole II.The center of said cylinder manifold 8 is provided with tail cone hole 8a.Be equipped with cooling water hole 12 on said water jacket 10 and the tail water cover 11.The center of said mouthful of mould 9, water jacket 10 and tail water cover 11 is equipped with the hole III of identical size.Cooling water hole 7b in the center of said back plug 7a is provided with.The right side of said mouthful of mould 9 is provided with groove 9a.
During work, 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 die holder 1 center, in the cavity that forms between plug 4a and rebound 6, cylinder manifold 8 and mouthful mould 9 before flowing to then, when the radwood fluid flow to the cavity between the hole II at preceding plug 4a and rebound 3 centers; The radwood fluid produces turbulent flow, redistributing the radwood fluid, when the radwood fluid flow to the cavity between the tail cone hole 8a at back plug 7a and cylinder manifold 8 centers; 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 flowed out the hole III at cylinder manifold 8 inlet port moulds 9 centers, the clad fluid was moulded layer with groove on through port mould 9 end faces and wood and is converged, owing to the hole less than mouth mould 9 centers, the hole on the left side, cylinder manifold 8 center; The clad fluid will coextru-lamination be moulded on the surface of layer at wood; And in mouth mould 9, be shaped, formation wood is moulded layer 15 and clad 14, along with wood is moulded layer 15 and clad 14 entering water jackets 10 and tail water cover 11; To cool off simultaneously from inside and outside through interior cooling water hole 7b and cooling water hole 11; Make wood mould layer 15 and clad 14 setting, this process is carried out continuously, has just formed wood and has moulded coating co-extrusion decoration materials.
