Abstract
The utility model discloses a tube-drawing type extruding mold with super thickness. The extruding mold comprises an extruding external mold and an extruding internal mold; the extruding external mold is in the stepped cylindrical tube shape and internally provided with a conical cavity; the tip end of the conical cavity of the extruded external mold is a barrel hole shaped bearing line; the extruding internal mold is a conical cavity and is internally provided with a conical hole cavity; the tip end of the conical hole cavity is a cylindrical barrel shaped bearing line; the conical cavity of the extruding external mold is matched with the external wall of the extruding internal mold; an annular cavity flow passage is formed between the conical internal wall of the extruding external mold and the external conical surface of the extruding internal mold, so as to lead plastic to be extruded through the cavity flow passage; the tensile balance degree of the mold is 1.03, and the tensile ratio is 3.41. The main parameters of the extruding internal mold are as follows: the aperture is 8.5 mm; the outside diameter is 10.5mm; the internal bearing line is 13.5 mm; the external bearing line is 6.0 mm; the internal angle is 7.63 degrees; and the external angle is 20.56 degrees; and the main parameters of the extruding external mold are as follows: the aperture is 17.0 mm; the bearing line is 5.0 mm and the internal angle is 24.87 degrees.
Description
Technical field
The utility model relates to a kind of super thickness pull-tube type extrusion die.
Technical background
Well-known wire cable insulating and sheath are extruded, and select normal temperature material such as polyolefin and polyvinyl chloride etc. for use, and thickness is more than 1.5mm; generally all adopt plsitive mold; thickness is even like this, and the external diameter high conformity is a hygroscopic materials for central core still; for the extruded product of nominal thickness more than 1.5mm; use the mould of squash type to be difficult to machine-shaping, not only external diameter is difficult to control, the bubble that the surface is continuous; influence the presentation quality of product, lost the protective effect of sheath.
The utility model content
The utility model is the defective that overcomes prior art, provides a kind of super thickness pull-tube type extrusion die, its normal temperature extruded material, super thickness squeezes the cooperation data of tubular type extrusion die, solved external diameter and be difficult to control, the continuous bubble in surface influences the presentation quality of product.
The utility model technical solution problem provides following scheme:
A kind of super thickness pull-tube type extrusion die, comprise and extrude external mold and extrude internal mold, the described external mold of extruding is step-like cylindrical tubular, there is a conical cavity inside, be the poroid line that holds of cylinder at the described external mold conical cavity tip of extruding, the described internal mold of extruding is a conically shaped, there is a tapered bore in portion within it, at described tapered bore tip is that one section cylindrical tube shape holds line, the described external mold conical cavity of extruding is complementary with the outer wall of extruding internal mold, described extrude the conical inboard wall of external mold and extrude between the internal mold male cone (strobilus masculinus) form a toroidal cavity runner, plastics are extruded by the cavity runner.
The stretching degree of balance 1.03 of described mould, draw ratio 3.41.The described internal mold major parameter of extruding: aperture 8.5mm; External diameter 10.5mm; In hold line 13.5mm; Hold line 6.0mm outward; 7.63 ° of interior angles; 20.56 ° of outer angles, the described external mold major parameter of extruding: aperture 17.0mm; Hold line 5.0mm; 24.87 ° of interior angles.
Description of drawings
Fig. 1 is a cast outer mold structure schematic diagram of the present utility model.
Fig. 2 is an internal model structure schematic diagram of the present utility model.
The specific embodiment
Referring to accompanying drawing, a kind of super thickness pull-tube type extrusion die, comprise and extrude external mold 1 and extrude internal mold 2, extrude external mold 1 and be step-like cylindrical tube for the radius difference, there is a conical cavity 3 inside, hold line 4 for circular hole always extruding external mold 1 cone point, extruding internal mold 2 is a conically shaped 5, there is a bellmouth in portion within it, at the bellmouth tip is that a cylindrical tube shape holds line 6, extrude external mold 1 conically shaped and be complementary, extrude the conical inboard wall of external mold 1 and extrude toroidal cavity runner of formation between internal mold 2 male cone (strobilus masculinus)s, plastics are extruded by the cavity runner with the outer wall of extruding internal mold 2.
Claims (2)
1. super thickness pull-tube type extrusion die, comprise and extrude external mold and extrude internal mold, it is characterized in that: the described external mold of extruding is step-like cylindrical tubular, there is a conical cavity inside, be the poroid line that holds of cylinder at the described external mold conical cavity tip of extruding, the described internal mold of extruding is a conically shaped, there is a tapered bore in portion within it, at described tapered bore tip is that one section cylindrical tube shape holds line, the described external mold conical cavity of extruding is complementary with the outer wall of extruding internal mold, described extrude the conical inboard wall of external mold and extrude between the internal mold male cone (strobilus masculinus) form a toroidal cavity runner, plastics are extruded by the cavity runner.
2. according to the described super thickness pull-tube type extrusion die of claim 1, it is characterized in that: the stretching degree of balance 1.03 of described mould, draw ratio 3.41, the described internal mold major parameter of extruding: aperture 8.5mm; External diameter 10.5mm; In hold line 13.5mm; Hold line 6.0mm outward; 7.63 ° of interior angles; 20.56 ° of outer angles, the described external mold major parameter of extruding: aperture 17.0mm; Hold line 5.0mm; 24.87 ° of interior angles.
