Description
Technical field
This utility model relates to extrusion die, particularly relates to a kind of multiple tube extrusion die.
Background technology
The multilamellar circulus of traditional multiple tube usually rule, uses traditional extrusion die can be prepared by.And work as
When the portion needing the multiple tube made is layered as acyclic irregular structure, traditional extrusion die cannot make, need spy
System extrusion die.Due to the irregular overlap that the outer layer of the multiple tube of required making is small-sized acyclic portion,
The exit opening then supplying the material making overlap to pass through on extrusion die is less, and material easily produces accumulation, and impact extrusion is multiple
Close the quality of pipe.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is to improve prior art, it is provided that
A kind of multiple tube extrusion die, solves in current technology when extrusion processing has the multiple tube of the irregular overlap of small size, appearance
Easily produce material stacking, the problem affecting multiple tube quality in the exit forming overlap.
For solving above technical problem, the technical solution of the utility model is:
A kind of multiple tube extrusion die, including termination, runner and core pattern, it is characterised in that described termination leads to runner
Crossing and be bolted on die holder, forming hole is offered at the middle part of termination, and the edge of forming hole has overlap hole, in the two of overlap hole
Side is provided with guide protrusions, offers sprue hole in the middle part of runner, is further opened with overlap runner hole, core pattern around sprue hole
It is interspersed in the forming hole of termination and in the sprue hole of runner.Multiple tube extrusion die described in the utility model utilizes core
Type is interspersed in the forming hole of termination, forms the forming area of multiple tube between forming hole and core pattern, the inner layer material of multiple tube
Injecting from the sprue hole of runner, and the cladding material of multiple tube injects from overlap runner hole, both are in the molding of end
Region between hole and core pattern is converged, and merges formation entirety by pressure extrusion, and inner layer material is fitted in core pattern
Formed circular, and if cladding material is directed to projection and is separated into arterial highway, enter into and different overlap holes be extruded into overlap,
Due to the effect of guide protrusions make cladding material more orderly enter in overlap hole, from without in narrow and small overlap hole
Pile up impact extrusion quality, be finally made internal layer be annulus outer layer be the irregular structure multiple tube of overlap.
Further, described overlap hole is provided with 8, and guide protrusions is provided with 8, sets according to the demand of reality application
Putting the shape quantity in overlap hole, cladding material is separated to form eight mutually incoherent roads by guide protrusions, flies subsequently into corresponding
Lateral opening formation lamellar is embedded in above internal layer, forms overlap.
Further, described core pattern hollow is also passed through compressed air, core pattern beyond termination cylinder on offer with
The passage of interior hollow section connection, compressed air is outwards discharged by passage, can play the multiple tube of extrusion molding
To cooling and the effect of sizing.
Further, described termination there are arc groove, cladding material and inner layer material in the opened above of forming hole
Arcuately groove flowing collects.
Further, described overlap runner hole is strip arcuation, is evenly distributed on around sprue hole.
Further, described overlap runner hole is provided with 4.
Compared with prior art, this utility model advantage is:
Bi-material is extruded by multiple tube extrusion die described in the utility model by special extrusion die simultaneously, system
Being made double-decker, and outer layer is non-annularity irregular structure, cladding material is guided shunting by guide protrusions makes it more orderly
Enter in overlap hole, from without piling up impact extrusion quality in narrow and small overlap hole, bi-material amalgamation is good, no
Easily separated, the multiple tube of given shape can be made according to the demand of reality application；This utility model simple in construction, cost of manufacture
Low, easy to use, production efficiency is high.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
A kind of multiple tube extrusion die disclosed in this utility model embodiment, produces the compound of the irregular overlap of non-annularity
Pipe, and do not have at overlap extrusion cavities extruded stock pile up thus affect extrusion quality, ectonexine amalgamation is good, the most easy-peel
From.
As shown in Figures 1 to 5, a kind of multiple tube extrusion die, including termination 1, runner 2 and core pattern 3, termination 1 and runner 2
Being bolted on die holder 4, forming hole 5 is offered at the middle part of termination 1, and the edge of forming hole 5 has overlap hole 6, is flying
The both sides of lateral opening 6 are provided with guide protrusions 11, and overlap hole 6 is provided with 8 edges being evenly distributed on forming hole 5, guides convex
Play 11 to be also 8 and be distributed between overlap hole 6, and have arc groove 10 in the opened above of forming hole 5.
Offer sprue hole 7 in the middle part of runner 2, around sprue hole 7, be further opened with overlap runner hole 8, overlap runner
Hole 8, in strip arcuation, is provided with 4, is evenly distributed on sprue hole 7 around.
Core pattern 3 bottom is cylindrical, is interspersed in the forming hole 5 of termination 1 and in the sprue hole 7 of runner 2, core pattern 3
