Abstract
The open a kind of multiple tube extrusion die of this utility model, including termination, runner and core pattern, it is characterized in that, described termination and runner are bolted on die holder, forming hole is offered at the middle part of termination, and the edge of forming hole has overlap hole, offers sprue hole in the middle part of runner, being further opened with overlap runner hole around sprue hole, core pattern is interspersed in the forming hole of termination and in the sprue hole of runner.Bi-material is extruded simultaneously is fabricated to double-decker by multiple tube extrusion die described in the utility model, and outer layer is non-annularity irregular structure, and bi-material amalgamation is good, is not readily separated, and can make the multiple tube of given shape according to the demand of reality application.
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.
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 extrusion die traditional in current technology and cannot make the compound of non-annularity irregular structure
The problem of pipe.
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, offers in the middle part of runner
Sprue hole, is further opened with overlap runner hole around sprue hole, and core pattern is interspersed in the forming hole of termination and runner
Sprue hole in.Multiple tube extrusion die described in the utility model utilizes core pattern to be interspersed in the forming hole of termination, molding
Forming the forming area of multiple tube between hole and core pattern, the inner layer material of multiple tube injects from the sprue hole of runner, and answers
The cladding material closing pipe injects from overlap runner hole, and both converge in the region between the forming hole and core pattern of end, and lead to
Excess pressure extruding merges formation entirety, and inner layer material is fitted in core pattern and is formed circular, and cladding material is from molding
The overlap hole of bore edges is extruded into overlap, 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, arranges the shape number in overlap hole according to the demand of reality application
Amount.
Further, described core pattern hollow logical compressed air, the core pattern cylinder beyond termination offers with interior
The passage of portion's hollow space connection, compressed air outwards discharges through passage, can play the multiple tube of extrusion molding
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, bi-material amalgamation is good, is not readily separated, can be according to reality
The demand of border application makes the multiple tube of given shape；This utility model simple in construction, 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 non-annularity irregular structure
Pipe, ectonexine amalgamation is good, is not easily stripped.
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, overlap
Hole 6 is provided with 8 edges being evenly distributed on forming hole 5, and has 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
Hollow is also passed through compressed air, offers, on the core pattern 3 cylinder beyond termination 1, the passage 9 connected with interior hollow section.
The inner layer material 12 of multiple tube injects from the sprue hole 7 of runner 2, and the cladding material 11 of multiple tube is from overlap
Runner hole 8 is injected, and cladding material 11 arcuately groove 10 collects, cladding material 11 and the inner layer material 12 forming hole 5 in termination 1
And the region between core pattern 3 is converged, and merging formation entirety by pressure extrusion, inner layer material 12 is fitted in core pattern 3
Upper formation is circular, and cladding material 11 is extruded into overlap from the overlap hole 6 at forming hole 5 edge, is finally made as shown in Figure 6
Internal layer be annulus outer layer be the irregular structure multiple tube of overlap.
Below it is only preferred implementation of the present utility model, it is noted that above-mentioned preferred implementation should not regard
For to restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim limited range.For
For those skilled in the art, without departing from spirit and scope of the present utility model, it is also possible to make some
Improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
