Abstract
The invention discloses a wood-plastic door pocket extrusion die and belongs to the technical field of dies. The die comprises a feed plate, a die body, a filter plate, a support plate, a convergent plate, a die orifice plate and a water cooling plate which are arranged sequentially, wherein the feed plate, the die body, the filter plate, the support plate, the convergent plate, the die orifice plate and the water cooling plate are all provided with internal flow passages, the internal flow passages are combined to form a first die cavity and a second die cavity which are communicated, and a die core is arranged in the second die cavity and extends into the first die cavity to form a shunt column; the inner diameter of the first die cavity and the outer diameter of the shunt column are gradually increased in a feeding direction. According to the invention, the first die cavity and the second die cavity are formed, the die core is arranged in the second die cavity, the shunt column is arranged in the first die cavity, so that pressure of a material in the die is increased, and the forming degree of the material is increased; the inner diameter of the first die cavity and the outer diameter of the shunt column are both increased gradually in the feeding direction, accordingly, the material has higher pressure in the die, the time for bearing higher pressure is prolonged, the forming degree of the material is increased, the quality of a door pocket is improved, and the service life of the door pocket is prolonged.
Description
technical field [0001] The invention relates to the technical field of moulds, in particular to a wood-plastic door casing extrusion die. Background technique [0002] Wood-plastic composite (WPC) is a modified thermoplastic material filled and reinforced with wood fiber or plant fiber. It combines the advantages of wood and plastic. It not only has the appearance of natural wood, but also overcomes its shortcomings. It has the advantages of anti-corrosion, moisture-proof, insect-proof, high dimensional stability, no cracking, and no warping. It has high hardness and wood-like workability. It can be cut, glued, fixed with nails or bolts, and can be painted. It is extruded or pressed into profiles, panels or other products, which can replace wood and plastic. Wood-plastic composite materials are made of wood ultra-fine powder mixed with polymer resin, and manufactured through molding technology. It has both the excellent characteristics of wood and plastic, and the products...
