Background technology
The drainage pipeline of installing in the existing structure is an individual layer tubing mostly, in drainage procedure, all can produce bigger noise, and noise almost comes out by whole transmission without reservation, causes the noise pollution of surrounding environment.Therefore, in recent years, people have developed a kind of noise reduction helix tube, and the inwall of this tubing is shaped on the helical form convex tendon, and during draining, water is pasting tube wall and is being vortex shape and flows, thereby reach the purpose of noise reduction.But, shortcoming such as there is complex structure in the processing mold of this tubing, and production efficiency is low, and cost is big, so, needing a kind of excellent noise reduction effect of exploitation, cost is low, tubing that production efficiency is high and processing mold.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art, provides a kind of and is used for processing tubing foamed core layer is arranged, and reach the noise reduction purpose, and cost investment is economized the core layer foaming noise reduction tubing extrusion die that production efficiency is high.
The technical scheme of the utility model core layer foaming noise reduction tubing extrusion die is: comprise the head connector on the cross-head of installation, the head connector through bolt connect flow distribution plate with after die body, the antetheca installing port mould of back die body; The mouth mould is installed pressing plate outward, and connects the back die body by screw, in mouthful mould plug is set; Form die cavity between plug and mouthful mould, plug connects large shunt awl and little minute flow cone, the outer feed cavity of formation between large shunt awl and little minute flow cone and the head connector; It is characterized in that being shaped on interior feed cavity in the described large shunt awl, in a side of flow distribution plate sandwich layer die head connector is installed, sandwich layer die head connector connects the sandwich layer extruder head; Be shaped on the sandwich layer feed cavity in the sandwich layer die head connector; Mesonexine is installed respectively in flow distribution plate is divided fluid and ectomesoderm to divide fluid, mesonexine divides formation internal layer shunting chamber between fluid and the plug, feed cavity in internal layer shunting chamber is communicated with; Ectomesoderm divides the outer shunting of formation chamber between fluid and the back die body; Outer shunting chamber is communicated with outer feed cavity, and mesonexine divides fluid and ectomesoderm to divide formation sandwich layer shunting chamber between the fluid, and the sandwich layer feed cavity is communicated with sandwich layer shunting chamber.
The utility model core layer foaming noise reduction tubing extrusion die, when extruding, material is feed cavity outside cross-head flows into, and flows into outer shunting chamber and the internal layer shunting chamber from outer feed cavity again; Simultaneously, the charging of sandwich layer feed cavity flows into sandwich layer shunting chamber; At last, three road materials compile, through the extruding of plug with mouthful mould; Form foamed core layer pipe, foamed core layer pipe has the function of sound-deadening and noise-reducing, has very outstanding advantage.The tubing extrusion die of this programme, the mode of three layers of shunting of employing, with the foamed core layer pipe extrusion molding, production efficiency is high.
The core layer foaming noise reduction tubing extrusion die of the utility model; Little flow distribution plate is installed in the head outer end of said plug, is shaped on little tap hole in the little flow distribution plate, and internal layer shunting chamber and interior feed cavity interconnect through little tap hole; Little tap hole has been arranged; It is convenient that internal layer shunting chamber is communicated with interior feed cavity, cooperates closely good airproof performance.Be equipped with the adjustment screw in the die body of described back, the adjustment screw contacts with a mouthful mould outer wall, the tight ness rating that cooperates of adjustment screw adjustment mouthful mould and back die body, make mouthful mould with after die body cooperate the tight ness rating height, do not leak material.
Description of drawings
Fig. 1 is the structural representation of the utility model core layer foaming noise reduction tubing extrusion die.
The specific embodiment
The utility model relates to a kind of core layer foaming noise reduction tubing extrusion die, comprises the head connector 1 on the cross-head of installation, head connector 1 through bolt 4 connect flow distribution plates 7 with after die body 13; The antetheca installing port mould 15 of back die body 13, mouthful mould 15 outer pressing plates 16 of installing, and by screw 17 connection back die bodys 13; In the mouth mould 15 plug 12 is set, forms die cavity 28 between plug 12 and mouthful mould 15, plug 12 connects large shunts awl 3 and little minute flow cone 2; The outer feed cavity 22 of formation between large shunt awl 3 and little minute flow cone 2 and the head connector 1; Feed cavity 21 in it is characterized in that being shaped in the described large shunt awl 3 is installed sandwich layer die head connector 19 in a side of flow distribution plate 7, and sandwich layer die head connector 19 connects the sandwich layer extruder head; Be shaped on sandwich layer feed cavity 23 in the sandwich layer die head connector 19; Mesonexine is installed respectively in flow distribution plate 7 is divided fluid 5 and ectomesoderm to divide fluid 11, mesonexine divides formation internal layer shunting chamber 24 between fluid 5 and the plug 12, feed cavity 21 in internal layer shunting chamber 24 is communicated with; Ectomesoderm divides the outer shunting of formation chamber 25 between fluid 11 and the back die body 13; Outer shunting chamber 25 is communicated with outer feed cavity 22, and mesonexine divides fluid 5 and ectomesoderm to divide formation sandwich layer shunting chamber 26 between the fluid 11, and sandwich layer feed cavity 23 is communicated with sandwich layer shunting chamber 26.When extruding, material is feed cavity 22 outside cross-head flows into, and flows into outer shunting chamber 25 and the internal layer shunting chamber 24 from outer feed cavity 22 again; Simultaneously, the charging of sandwich layer feed cavity flows into sandwich layer shunting chamber 26; At last, three road materials compile, through the extruding of plug with mouthful mould; Form foamed core layer pipe, foamed core layer pipe has the function of sound-deadening and noise-reducing, has very outstanding advantage.The tubing extrusion die of this programme, the mode of three layers of shunting of employing, with the foamed core layer pipe extrusion molding, production efficiency is high.Little flow distribution plate 9 is installed in the head outer end of said plug 12, is shaped on little tap hole 27 in the little flow distribution plate 9, and internal layer shunting chamber 24 interconnects through little tap hole 27 with interior feed cavity 21; Little tap hole has been arranged; It is convenient that internal layer shunting chamber is communicated with interior feed cavity, cooperates closely good airproof performance.Be equipped with adjustment screw 14 in the die body 13 of described back, adjustment screw 14 contacts with mouthful mould 15 outer walls, the tight ness rating that cooperates of adjustment screw adjustment mouthful mould and back die body, make mouthful mould with after die body cooperate the tight ness rating height, do not leak material.
