Abstract
The invention discloses a PE wood-plastic co-extrusion flow line mold which comprises a mold body used for extrusion molding. Hollow cavities are formed in a machine neck, a compression plate, a support plate, a premolding plate, a molding plate and a co-extrusion plate of the mold body correspondingly. The hollow cavities are combined into a mold cavity with the cross section tending to be in a long strip shape. Co-extrusion flow channels with multiple bent channels are arranged in the co-extrusion plate. The co-extrusion flow channels communicate with the long-strip-shaped mold cavity through cladding openings. The cladding openings are distributed around the cavity wall of the long-strip-shaped mold cavity. Due to the fact that the multiple bent channels re arranged in the co-extrusion flow channels, color masterbatch entering the long-strip-shaped mold cavity through the co-extrusion flow channels is turned and dispersed in the multiple bent channels arranged in the input flow channels and the cladding flow channels, and finally an even flow line effect is formed on the surface of a PE wood-plastic composite inner core. Meanwhile, the cladding openings are arranged to be distributed around the cavity wall of the long-strip-shaped mold cavity, and therefore the surface of the PE wood-plastic composite inner core is evenly clad with a PE material outer film.
