Abstract
A kind of extrusion die, comprise die body, shunting comb, mouth mould and gland, described die body has an inner chamber, and this inner chamber is divided into straight section, typhon section and toy trumpet section, described typhon section and toy trumpet section retract port connect; Shunting comb is provided with on the right of described straight section; Described mouth mould comprises enlarged diameter section and reduced diameter section, described enlarged diameter section is positioned at described straight section and has a conical cavity, this conical cavity right-to-left is the form that footpath, chamber diminishes gradually, and described reduced diameter section is positioned at gland cavity and has an axially extending bore, and this axially extending bore communicates with conical cavity; The interior inclined-plane of described typhon section, enlarged diameter section and the outer inclined-plane of rhombogen form two arch runners about die body axial centre symmetry; Described gland is fixed on the left side of described die body by screw.Owing to adopting above-mentioned structural design, namely shunting comb is set in die body, realizes extruding the meticulous of molten state plastics, ensure that the plastic material circularity precision extruded is high.
Description
Technical field
The utility model relates to technical field of mold, particularly a kind of high-accuracy extrusion die.
Background technology
The extrusion system of extruder is the important component part of extruder.Extrusion system comprises screw rod, barrel, head, extrusion die are first-class, and the plastic melt of rotary motion is transformed into parallel lines motion by head, and uniform and stable ground imports in extrusion die, and plastics are evenly extruded by extrusion die.Extrusion die in the past has a conical internal cavity and shape chamber always, the form that this conical cavity diminishes gradually in footpath, chamber from left to right, the right-hand member of conical cavity communicates with straight shape chamber, the plastics of molten state are squeezed to straight shape chamber by conical internal cavity by the extrusion die of said structure design, extrude finally by straight shape chamber, obviously this kind of extrusion way is comparatively coarse, its plastic wire circularity low precision extruded.
Therefore, prior art needs to be improved and improves.
Summary of the invention
For overcoming the above-mentioned problems in the prior art, the purpose of this utility model is the structural design by high-accuracy extrusion die, realizes meticulous extruding, and makes the plastic wire circularity precision extruded high.
The utility model realizes above-mentioned purpose by following technological means:
A kind of extrusion die, comprise die body, shunting comb, mouth mould and gland, described die body has an inner chamber, and this inner chamber is divided into straight section, typhon section and toy trumpet section, described typhon section and toy trumpet section retract port connect; Be provided with on the right of described straight section shunting comb, the longitudinal bodies comprising rhombogen and be solidified as a whole with it is combed in this shunting, and described longitudinal bodies is positioned at the middle part of rhombogen, this longitudinal bodies and straight section inwall suitable; Described mouth mould comprises enlarged diameter section and reduced diameter section, described enlarged diameter section is positioned at described straight section and has a conical cavity, this conical cavity right-to-left is the form that footpath, chamber diminishes gradually, and described reduced diameter section is positioned at gland cavity and has an axially extending bore, and this axially extending bore communicates with conical cavity; The interior inclined-plane of described typhon section, enlarged diameter section and the outer inclined-plane of rhombogen form two arch runners about die body axial centre symmetry; Described gland is fixed on the left side of described die body by screw.
Compared with prior art, the beneficial effects of the utility model are: owing to adopting above-mentioned structural design, in die body, namely arrange shunting comb, realize extruding the meticulous of molten state plastics, ensure that the plastic wire circularity precision extruded is high.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
In figure, each label respectively: (1) die body, (2) shunting comb, (3) mouth mould, (4) gland, (11) straight section, (12) typhon section, (13) toy trumpet section, (21) rhombogen, (22) longitudinal bodies, (31) enlarged diameter section, (32) reduced diameter section, (311) conical cavity, (321) axially extending bore, (14) (15) arch runner.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Please refer to Fig. 1, a kind of extrusion die of the utility model, comprise die body 1, shunting comb 2, mouth mould 3 and gland 4, described die body 1 has an inner chamber, this inner chamber is divided into straight section 11, typhon section 12 and toy trumpet section 13, described typhon section 12 and toy trumpet section 13 retract port connect; Be provided with shunting comb 2 on the right of described straight section 11, the longitudinal bodies 22 comprising rhombogen 21 and be solidified as a whole with it is combed in this shunting, and described longitudinal bodies 22 is positioned at the middle part of rhombogen 21, and this longitudinal bodies 22 is suitable with straight section 11 inwall; Described mouth mould 3 comprises enlarged diameter section 31 and reduced diameter section 32, described enlarged diameter section 31 is positioned at described straight section 11 and has a conical cavity 311, this conical cavity 311 right-to-left is the form that footpath, chamber diminishes gradually, described reduced diameter section 32 is positioned at gland cavity and has an axially extending bore 321, and this axially extending bore 321 communicates with conical cavity 311; The interior inclined-plane of described typhon section 12, enlarged diameter section 31 and the outer inclined-plane of rhombogen 21 form two arch runners 14,15 about die body axial centre symmetry; Described gland 4 is fixed on the left side of described die body 1 by screw.
During utility model works, after first the plastics of molten state are squeezed into toy trumpet section 13, by shunting comb 2, it is shunted, enter two arch runners 14,15 respectively, finally extruded by axially extending bore 321 again, due to the plastics of the twice extrusion molten state in outer inclined-plane of inclined-plane and rhombogen 21 in typhon section 12, enlarged diameter section 31, realize the retrofit of plastic material, and then realize extruding of the high plastic wire of circularity precision, thus realize the purpose of this utility model.
The above, only better enforcement of the present utility model, not any pro forma restriction is done to the utility model, any those skilled in the art may utilize above-mentioned technology contents to be changed or be modified to the Equivalent embodiments of equivalent variations, at this, allly do not depart from the technical solution of the utility model content, the any simple modification just done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
