Abstract
The utility model discloses a co-extrusion type sandwich extrusion die (1) which comprises a main feeding hole (2), an auxiliary feeding hole (3), a neck (4), an outer frame sprue spreader (5), an auxiliary inner core feeding hole (9), a bearing plate (13), a frame compression sleeve (6), a frame shaping sleeve (7), a frame die (8), a core mold (11), a core compression sleeve (10) and a core die (12), wherein the core die (12) is longer than the frame die (8); a main extrusion machine provides frame raw materials a for the main feeding hole (2); an auxiliary extrusion machine provides core materials b for the auxiliary feeding hole (3); the core materials b directly enter a cavity in a frame-shaped structure to finish production of sandwich decoration plates and sandwich deformed sections.
Description
Technical field
The utility model relates to a kind of co-extrusion type sandwich extrusion neck ring mold mould.
Background technology
When single screw rod, double-screw plastic extrusion machine are produced decorative panel, special-shaped section product continuously, must extrusion neck ring mold mould be installed at extruder discharging mouth, be used for the raw material under molten condition to shunt and shape to reach the structural requirement of design.The material of product is even, solid colour.Horn of plenty kind can be carried out color coextrusion to the visual end face of some product, when producing product, extrude color material to one of the design of extrusion neck ring mold die face with the runner of colored surface river outlet with another extruder, utilize the compatibility of bi-material under heat fusing state to make product surface cover last layer color and realize, bi-material is to merge mutually rich colors on the surface of product parison.
When actual use Plastic decorative panel, profile shapes, people can propose some new requirements to its performance, as the intensity, the raising that strengthen while application are incubated and sound insulation function, can only adopt and strengthen the thickness of product wall or the more additional devices of product are reached to result of use, increase cost and difficulty of construction.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of co-extrusion type sandwich extrusion neck ring mold mould, is arranged on extruder discharging mouth and can continuously produces sandwich decoration board and sandwich special-shaped section, meets the new functional requirement that market proposes product.
For addressing the above problem, co-extrusion type sandwich extrusion neck ring mold mould of the present utility model by bulk supply mouth, secondary inlet, machine neck, housing spreader, inner core secondary feeding mouth, support plate, frame wedging ring, core wedging ring, confine jacket core, frame mouth mould, core mouth mould and form.Main extruder discharging opening connects with mould bulk supply mouth machine neck, make the frame raw material of sandwich decoration board, sandwich profile shapes from bulk supply mouth implanter neck, by housing spreader flow through frame wedging ring, confine jacket, form the frame-shaped construction of product along mandrel surface from frame mouth mould, secondary extruder discharging mouth connects with secondary inlet simultaneously, coremaking material enters into inner core wedging ring from the secondary feeding mouth runner of inner core in the inside of core, flows out the core that directly enters into established frame-shaped construction internal cavities formation sandwich decoration board, sandwich special-shaped section parcel from core mouth mould.Core is supported by the wall of support plate and inner core feeding mouth, and core mouth mould length is greater than frame mouth mould, prevents that raw-material moulding produces interference to sandwich material to frame.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the cutaway view of the utility model co-extrusion type sandwich extrusion neck ring mold principles of die structure embodiment.
Fig. 2 is the A-A cutaway view of the utility model co-extrusion type sandwich extrusion neck ring mold mould.
Fig. 3 is the secondary feeding mouth B-B of the inner core cutaway view of the utility model co-extrusion type sandwich extrusion neck ring mold mould.
The specific embodiment
The known die main body 1 of cutaway view of the sandwich of co-extrusion type shown in Fig. 1 extrusion neck ring mold principles of die structure figure embodiment has two raw material inlets of major-minor 2,3, main extruder injects die main body 1 by the raw material a that makes frame from bulk supply mouth 2 to machine neck 4, and by the material b that makes core, from secondary inlet 3 to inner core, secondary feeding mouth 9 enters die main body 1 to secondary extruder simultaneously.Main extruder by the raw material a that makes framework from the machine neck 4 of inlet 2 to frame spreader 5, frame wedging ring 6, confine jacket 7 and flow out along the surface of core 11 the shaped as frame main body that forms product from frame mouth mould 8, secondary extruder is extruded the material b that makes core to be filled to frame internal cavities to core mouth mould 12 from core 11 inside through core wedging ring 10 from the secondary feeding mouth 9 of inner core.Core 11 is fixed by the wall of support plate 13 and the secondary feeding mouth 9 of inner core, the length of core mouth mould 12 is greater than frame mouth mould 8, make the core material that established internal cavities can adapt to different performance that enters into that the material of core just can be synchronous, avoid coremaking material to interfere with the forming process of framework.
The A-A cutaway view of co-extrusion type sandwich extrusion neck ring mold mould as shown in Figure 2, frame mouth mould 8 is wrapped in the cavity filling that core mouth mould 12 can form coremaking material.
The cross section of the secondary feeding mouth 9 of the known inner core of the secondary feeding mouth B-B of inner core cutaway view of the sandwich of co-extrusion type shown in Fig. 3 extrusion neck ring mold mould is streamlined oval cone, reduces the raw-material retardance of framework, reduces the impact on shaped as frame main body.
The utility model is not limited to the above-mentioned specific embodiment; as long as Cai Liao Gong Give runner is set in the core inside of frame spreader; wrapped core extrusion neck ring mold is installed; no matter how inner structure size is adjusted; in mould, how local runner angle changes, within all dropping on protection domain of the present utility model.
Claims (2)
1. a co-extrusion type sandwich extrusion neck ring mold mould, by bulk supply mouth, secondary inlet, machine neck, housing spreader, the secondary feeding mouth of inner core, support plate, frame wedging ring, core wedging ring, confine jacket, core, frame mouth mould, core mouth mould composition, is characterised in that: extrusion neck ring mold die main body (1) has two inlets (2 of major-minor, 3), main extruder will be made the raw material a of frame from the machine neck (4) of bulk supply mouth (2) to frame spreader (5), frame wedging ring (6), confining jacket (7) flows out and forms frame main body from frame mouth mould (8) along the surface of core (11), secondary extruder enters the secondary feeding mouth of inner core (9) by the material b that makes core from secondary inlet (3) and extrudes and be filled to frame internal cavities to core mouth mould (12) from core (11) is inner through core wedging ring (10), core (11) is fixed by the wall of support plate (13) and the secondary feeding mouth of inner core (9), and the length of core mouth mould (12) is greater than frame mouth mould (8).
