Abstract
The invention relates to the technical field of plastic production, and relates to a coextrusion mold of a plastic cylindrical bar and the plastic cylindrical bar. The coextrusion mold of the plastic cylindrical bar comprises a mold body, wherein the rear surface of a front section of mold cavity and the side surface of the mold are also provided with second inlet leading to the mold cavity; a plurality of triangular grooves surrounding for a circle are formed around the outer side of the front section mold cavity; the profile of the outer periphery of a rear mold cavity is the circular arc connecting line of vertexes outside the triangular grooves; a circumferential distribution groove is formed in the inner side of the second inlet of the mold body; the mold for producing a two-layer cylindrical bar has the advantages of simple production technology and low production cost; the plastic cylindrical bar comprises an inner layer structure and an outer layer structure; the inner layer and the outer layer are provided with a plurality of triangular bulged structure surrounding for a circle; the plastic cylindrical bar has the advantages of relatively good combination of the inner layer and the outer layer and difficulty in falling off and beautiful products because of patterns on the outer layer of the cylindrical bar.
Description
Technical field
The present invention relates to technical field of plastic production, specifically relate to the mould producing plastic cylinder rod, also relate to a kind of plastic cylinder rod.
Background technology
Mould has die ontology, and die ontology has die cavity, and die ontology has import above and outlet below, is exactly die cavity between import and outlet, and in the middle of plastic cylinder rod mould, the cross section of die cavity is circular; In prior art, die cavity only has an import, namely use a kind of raw material, the plastic cylinder rod produced also is a kind of material, sometimes in order to cost-saving, lower-cost material is arranged in cylindrical rod inside, will secondary extrusion produces, secondary extrusion is produced has complex manufacturing, shortcoming that cost is high.
The plastic cylinder rod that the bi-material produced with said method is formed, the material outside its cross section is also the structure of annular, have that ectonexine combines bad, easily come off, the shortcoming of product aesthetic property difference.
Summary of the invention
Object of the present invention is exactly for above-mentioned shortcoming, the plastic cylinder provide the plastic cylinder rod that a kind of production technology is simple, production cost is low co-extruding mould, also provide a kind of ectonexine using this mould to produce to combine better simultaneously, being not easy to come off, product is attractive in appearance is excellent.
The technical scheme of plastic cylinder rod co-extruding mould of the present invention is achieved in that plastic cylinder rod co-extruding mould, comprise die ontology, die ontology has die cavity, die ontology has import above and outlet below, be exactly die cavity between import and outlet, leading portion die cavity at the die cavity of entrance one end, it is characterized in that: after described leading portion die cavity, mould side also has the second import to lead to die cavity, second import die cavity is below rear die cavity, described leading portion die cavity outer periphery has multiple, the triangular groove rounded, the profile of described rear die cavity periphery is exactly the circular arc line of the outer vertex of surface of triangular groove, there is in the inner side of the second import department of described die ontology one week distributing slot.
The technical scheme of plastic cylinder rod of the present invention is achieved in that plastic cylinder rod, comprise endothecium structure and layer structure, it is characterized in that: described internal layer skin has multiple triangular hill structure rounded, the outward flange of described layer structure is the circular arc line of the outer vertex of surface of triangular hill structure.
The invention has the beneficial effects as follows: when such plastic cylinder rod co-extruding mould produces two-layer cylindrical rod, there is the advantage that production technology is simple, production cost is low; Such plastic cylinder rod has ectonexine and combines better, do not allow caducous advantage, simultaneously because the outer field striped of cylindrical rod has product advantage attractive in appearance.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of plastic cylinder of the present invention rod co-extruding mould.
Fig. 2 is the structural representation of plastic cylinder rod of the present invention.
Wherein: 1, die ontology 2, import 3, outlet 4, die cavity 5, second import 41, front end die cavity 42, rear die cavity 6, triangular groove 7, endothecium structure 8, layer structure.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, plastic cylinder rod co-extruding mould, comprise die ontology 1, die ontology has die cavity 4, die ontology has import 2 above and outlet 3 below, be exactly die cavity 4 between import and outlet, leading portion die cavity 41 at the die cavity of entrance one end, it is characterized in that: after described leading portion die cavity, mould side also has the second import 5 to lead to die cavity, second import die cavity is below rear die cavity 42, described leading portion die cavity outer periphery has multiple, the triangular groove 6 rounded, the profile of described rear die cavity periphery is exactly the circular arc line of the outer vertex of surface of triangular groove, there is in the inner side of the second import department of described die ontology one week distributing slot.
During use, enter the first raw material by import, make the plug of cylindrical rod, leg-of-mutton projection will be formed owing to there being triangular groove outside leading portion die cavity 41; Second import extrudes the second raw material, and it forms the parts outside cylindrical rod, because leg-of-mutton projection plays a part support on the wall of rear die cavity 42, the phenomenon offset can not be there is in plastic cylinder rod, ensure that concentricity, it once extrudes and also has technique simply, the advantage that cost is low simultaneously.Described distributing slot ensure that the raw material that the second import enters can reach each sideway stance.
As shown in Figure 2, plastic cylinder rod, comprise endothecium structure 7 and layer structure 8, it is characterized in that: described internal layer skin has multiple triangular hill structure rounded, the outward flange of described layer structure is the circular arc line of the outer vertex of surface of triangular hill structure.Like this owing to there being the staggered effect of triangular hill, its have combine more closely, the advantage of not easily delamination, triangular hill has striped outside plastic cylinder rod, has advantage more attractive in appearance.
The foregoing is only specific embodiments of the invention, but architectural feature of the present invention is not limited to this, any those skilled in the art is in the field of the invention, and the change done or modification are all encompassed in the scope of the claims of the present invention.
Claims (2)
1. plastic cylinder rod co-extruding mould, comprise die ontology, die ontology has die cavity, die ontology has import above and outlet below, be exactly die cavity between import and outlet, leading portion die cavity at the die cavity of entrance one end, it is characterized in that: after described leading portion die cavity, mould side also has the second import to lead to die cavity, second import die cavity is below rear die cavity, described leading portion die cavity outer periphery has multiple, the triangular groove rounded, the profile of described rear die cavity periphery is exactly the circular arc line of the outer vertex of surface of triangular groove, there is in the inner side of the second import department of described die ontology one week distributing slot.
2. plastic cylinder rod, comprises endothecium structure and layer structure, it is characterized in that: described internal layer skin has multiple triangular hill structure rounded, and the outward flange of described layer structure is the circular arc line of the outer vertex of surface of triangular hill structure.
