Abstract
The invention discloses a co-extrusion type sandwich extrusion mouth mold die, the die 1 comprises a main feeding port 2, an auxiliary feeding port 3, a machine neck, an outer frame spure spreader 5, an inner core auxiliary material inlet 9, a supporting plate 13, a frame compression cover 6, a frame shaping cover 7, a frame mouth mold 8, a core mold 11, a core compression cover 10, a core mouth mold 12 and other main parts, the core mouth mold 12 is longer than the frame mouth mold 8, a main extruder provides a frame raw material a to the main feeding port 2, an auxiliary extruder provides a core material b to the auxiliary feeding port 3, and the core making material b directly enters an inner cavity of the frame shaped structure to complete the production of sandwich decorative boards and sandwich special-shaped profiles.
Description
Technical field
The present invention relates to a kind of co-extrusion type sandwich extrusion neck ring mold mould.
Background technology
At extruder discharging mouth, extrusion neck ring mold mould must be installed when singe screw, double-screw plastic extrusion machine continuous seepage decorative panel, special-shaped section product, be used for shunting the raw material under molten condition and shaping reaching the structural requirement of design.The uniform in material of product, solid colour.Horn of plenty kind can carry out color coextrusion to the visual end face of some product, the runner producing one and the colored surface river outlet designed extrusion neck ring mold die face with another extruder while product extrudes color material, utilize the compatibility of bi-material under hot melt state to make product surface cover last layer color to realize, bi-material merges rich colors mutually on the surface of product parison.
When actual use Plastic decorative panel, profile shapes, people can propose some new requirements to its performance, intensity during as strengthened application, improve insulation and sound insulation function, the thickness of larger production wall can only be adopted or some devices are added to reach result of use to product, add cost and difficulty of construction.
Summary of the invention
The technical problem to be solved in the present invention 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, meet the New function requirement that market proposes product.
For solving the problem, co-extrusion type sandwich extrusion neck ring mold mould of the present invention by bulk supply mouth, secondary inlet, machine neck, housing spreader, inner core secondary feeding mouth, support plate, frame wedging ring, core wedging ring, confine several critical pieces such as jacket core, frame mouth mould, core mouth mould and form, its SMIS mouth mould length is greater than frame mouth mould.Main extruder discharging opening connects with mould bulk supply mouth machine neck, the frame raw material of making sandwich decoration board, sandwich profile shapes are from bulk supply mouth implanter neck, flow through frame wedging ring by housing spreader, confine jacket, the frame-shaped construction of product is formed 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 directly enter into the core that established frame-shaped construction internal cavities forms 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 sandwich material to the raw-material shaping generation interference of frame.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the sectional view of co-extrusion type sandwich extrusion neck ring mold principles of die structure embodiment of the present invention.
Fig. 2 is the A-A sectional view of co-extrusion type sandwich extrusion neck ring mold mould of the present invention.
Fig. 3 is the inner core secondary feeding mouth B-B sectional view of co-extrusion type sandwich extrusion neck ring mold mould of the present invention.
Detailed description of the invention
The known die main body 1 of sectional view of the sandwich of co-extrusion type shown in Fig. 1 extrusion neck ring mold principles of die structure figure embodiment has major-minor two raw material inlets 2,3, the raw material a making frame is injected die main body 1 from bulk supply mouth 2 to machine neck 4 by main extruder, and by the material b of making core, from secondary inlet 3 to inner core, secondary feeding mouth 9 enters die main body 1 to secondary extruder simultaneously.Make the raw material a of framework from the machine neck 4 of inlet 2 to frame spreader 5, frame wedging ring 6, confine jacket 7 and flow out the shaped as frame main body forming product along the surface of core 11 from frame mouth mould 8, the material b making core to extrude from core 11 inside to core mouth mould 12 through core wedging ring 10 from inner core pair feeding mouth 9 and is filled to frame internal cavities.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, what make that the material of core just can be synchronous enters into the core material that established internal cavities can adapt to different performance, avoids coremaking material to interfere with the forming process of framework.
The A-A sectional 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 makes coremaking material formed.
The cross section of the secondary feeding mouth 9 of the known inner core of the secondary feeding mouth B-B sectional view of inner core of the sandwich of co-extrusion type shown in Fig. 3 extrusion neck ring mold mould is streamlined elliptical cone, reduces the raw-material retardance of framework, reduces the impact on shaped as frame main body.
The present invention is not limited to above-mentioned detailed description of the invention; as long as arrange Cai Liao Gong Give runner in the core inside of frame spreader, wrapped core extrusion neck ring mold is installed, no matter how inner structure size adjusts; in mould, how local runner angle changes, and all drops within protection scope of the present invention.
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, several critical piece composition such as core mouth mould, its SMIS mouth mould length is greater than frame mouth mould, is characterised in that: extrusion neck ring mold die main body (1) has major-minor two inlets (2), (3), main extruder will make the raw material a of frame from the machine neck (4) of bulk supply mouth (2) to frame spreader (5), frame wedging ring (6), confine jacket (7) and flow out formation frame main body along the surface of core (11) from frame mouth mould (8), the material b making core is entered the secondary feeding mouth (9) of inner core from secondary inlet (3) and is filled to frame internal cavities through core wedging ring (10) from inner to extrude to core mouth mould (12) of core (11) by secondary extruder, core (11) is fixed by the wall of support plate (13) and the secondary feeding mouth (9) of inner core, and the length of core mouth mould (12) is greater than frame mouth mould (8).
