Abstract
An imitating wood grain plastic profile containment co-extrusion mould, including a connecting sleeve, a support plate, a compression set and a cavity of the fixed mould board comprising into a materials channel. The materials channel is provided with a core mould, a forming export of the plastic profile is formed between the core mould and the inner wall of the fixed mould board, the fixed mould board comprises a based materials extrusion fixed mould board and a co-extrusion fixed mould board, a co-extrusion channel is installed between the based materials extrusion fixed mould board and the co-extrusion fixed mould board, the co-extrusion channel is connected with outside the co-extrusion machine by the co-extrusion joint. The wood grain materials are input by the co-extrusion machine on the setting part of the moulding head of the utility model, enter into the co-extrusion channel around the cavity, and enter into the co-extrusion gap, then converge with the based materials, the wood grain utilizes the channel to make the co-extrusion materials to form velocity difference implementation in the setting plate, producing direct stria or the annual ringed wood grains, which are lifelike in appearance and has a wood qualitative sense. The mould is simple in structure and easy in manufacture.
Description
Technical field
The utility model relates to a kind of plastics abnormity material extrusion die, and the plastics abnormity material that particularly cooperates certain raw material can produce imitative wood grain contains the coextrusion mould.
Background technology
The manufacture method of existing imitative wood grain plastics abnormity material is Masterbatch to be sneaked into adopt the method for mixing co-extrusion among the ordinary white PVC, and the section bar woodiness touch that this method is produced is not strong; Or on extruding production line, inject wood grain mill base, the section bar wood grain instability that this method is produced; Or use surperficial coating technique, the section bar surface that this method is produced is scratched easily.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, proposed a kind of imitative wood grain and contained the coextrusion mould, cooperated certain coextrusion raw material can produce diversified imitative wood grain plastic irregular profile with timber native texture by extrusion die provided by the utility model.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of imitative wood grain plastic irregular profile contains the coextrusion mould, it is provided with adapter sleeve successively, support plate, wedging ring and stereotype plate, adapter sleeve, support plate, the cavity of wedging ring and stereotype plate constitutes the passage of material turnover, be provided with core in the passage of material turnover, constitute plastic irregular profile moulding outlet between core and the stereotype plate inwall, between support plate inwall and core periphery, be provided with the shunting muscle that supports core, be characterized in: stereotype plate is divided into base material extrusioning shaping plate and coextrusion stereotype plate, base material extrusioning shaping plate is provided with co-extruding flow channel between the extrusioning shaping plate together, co-extruding flow channel communicates with outside co-extrusion machine by the co-extrusion joint, described co-extruding flow channel is provided with ring-type co-extrusion sprue and some branches runner, sprue and branch's runner communicate with die cavity by the gap runner, coextrusion stereotype plate die cavity is than the peripheral big 0.2-0.3 millimeter in base material extrusioning shaping template chamber, so that formation coextruded layer, wood grain then utilize runner to make the co-extrusion material form speed difference in stereotype plate and realize.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, because the extrusion temperature of co-extrusion material hangs down 40-50 ℃ than the extrusion temperature of PVC base-material, therefore co-extruding flow channel is designed in the exit near extrusion die, the place is provided with the co-extrusion inlet at distance moulding outlet 20-60 millimeter.
The utility model compared with prior art, the utility model is in the typing part of die head, with co-extrusion machine input wood grain material, enter co-extruding flow channel, enter the co-extrusion gap again, converge with base material then around die cavity, wood grain is then utilized runner to make the co-extrusion material form speed difference in stereotype plate and is realized, produce the wood grain of straight burr and year colyliform, outward appearance is true to nature, and woodiness touch is arranged.Its mould structure is simple, and is easy to manufacture.
