Description
Technical field
The present invention relates to the extrusion die of aluminium alloy extrusions, especially for the hot-extrusion mold of the multicore chamber aluminium alloy extrusions of moulding cross section structure complexity and metal for the stream method.
Background technology
The mould that is used for extrusion modling multicore chamber aluminium alloy extrusions at present adopts the mode of perforation for stream, the upper die and lower die of its mould are monolithic construction, offer some perforation at the sidewall of interior nib, nib in external metallization is introduced by this perforation, nib for stream in realizing.Thisly have following defective for flow structure: 1, since in will realizing nib for stream function, the perforation of interior nib sidewall need be done very big, has a strong impact on the structural strength of outer core rod, die life weak point.2, product moulding instability.3, adopt all-in-one-piece patrix, the Mould Machining difficulty can't be produced the multicore chamber aluminium alloy extrusions of cross section structure complexity.4, mainly by the manual processing of electric spark technology, machining accuracy can't guarantee that error is big, and mould is repaired difficulty for the patrix of this monolithic construction, perforation structure.
Summary of the invention
The purpose of this invention is to provide a kind of hot-extrusion mold that is used for moulding multicore chamber aluminium alloy extrusions, this is long die life, be easy to processing and repair, and product moulding is stable when producing.
For reaching above-mentioned purpose, the present invention is used for the hot-extrusion mold of moulding multicore chamber aluminium alloy extrusions, comprise upper die and lower die, described patrix is formed by upper strata mould and lower floor's die combination, described upper strata mould is provided with inner mould core and some first tap holes, the bottom of described lower floor mould is provided with the outer core rod with interior nib, the top of lower floor's mould is provided with and described interior the 3rd coaxial tap hole of nib, and some second tap holes that run through lower floor mould upper and lower end face, constitute outer nib for circulation road from first tap hole through the outer nib of second tap hole to counterdie, from first tap hole through the 3rd tap hole nib confession circulation road in the nib formation in described.
Further, described the 3rd tap hole is up big and down small tapered, and described some second tap holes are positioned at around the 3rd tap hole, and corresponding, interior half one with second tap hole of outer half one of first tap hole is corresponding with the 3rd tap hole.
Further, described upper strata mould and lower floor's mould adopt fixing structure and pin location.
The present invention also provides a kind of metal of hot extrusion molding multicore chamber aluminium alloy extrusions that is used for for the stream method, this confession stream method adopts the combined type patrix that is made of upper strata mould and lower floor's mould, at the patrix layer some first tap holes are set, be provided with and the 3rd tap hole that interior nib is coaxial and some second tap holes that run through lower floor mould upper and lower end face on the top of lower floor's mould, apply extruding force, make metal flow inject second tap hole and the 3rd tap hole simultaneously from first tap hole, and then inject outer nib and interior nib respectively, thereby realize that outer nib and interior nib are independently for stream.
Compared with prior art, the patrix of extrusion die of the present invention adopts the combined type patrix that is made of upper strata mould and lower floor's mould, and upper strata mould and lower floor's mould can separate independent processing, agent structure all can be finished at Mechanical Processing Center, easy to process, the machining accuracy height, and also follow-up easy to maintenance; Simultaneously, this combined type patrix makes that outer nib and interior nib can be independently for streams.
Outer nib and interior nib adopt respectively and independently supply circulation road, for stream directly, put in place, accurately, product moulding is stable during production, and the perforation of nib sidewall in can reducing, and reaches the beneficial effect that increases outer core rod intensity, improves die life.
The upper strata mould and the lower floor's mould that constitute patrix adopt fixing structure and pin location, the assembly precision height, and Stability Analysis of Structures, convenient disassembly makes things convenient for mould to repair.
Metal of the present invention adopts knockdown patrix and inside and outsidely independently can realize the multicore chamber aluminium alloy extrusions of production cross section complexity for the stream mode for the stream method, and can control easily metal flow quantity delivered and metal flow to.

The specific embodiment
The present inventor utilizes the practical experience and the mould design expertise of long-term accumulation, defective at the aluminium alloy extrusions extrusion die existence of existing multicore chamber, invented inside and outside independent metal and supplied the stream method, and proposed a kind of hot-extrusion mold that is used for moulding multicore chamber aluminium alloy extrusions on this basis for stream.The present invention will be further described below in conjunction with drawings and Examples.
The metal that the present invention is used for hot extrusion molding multicore chamber aluminium alloy extrusions for the stream method is: adopt the combined type patrix that is made of upper strata mould and lower floor's mould, at the patrix layer some first tap holes are set, be provided with and the 3rd tap hole that interior nib is coaxial and some second tap holes that run through lower floor mould upper and lower end face on the top of lower floor's mould, apply extruding force, make metal flow inject second tap hole and the 3rd tap hole simultaneously from first tap hole, and then inject outer nib and interior nib respectively, thereby realize that outer nib and interior nib are independently for stream.
With reference to Fig. 1-5, the hot-extrusion mold that originally is used for moulding multicore chamber aluminium alloy extrusions comprises: patrix 1 and counterdie 2.Wherein, described patrix 1 is combined by upper strata mould 11 and lower floor's mould 12, described upper strata mould 11 is provided with inner mould core 111 and three first tap holes 112, the bottom of described lower floor mould 12 is provided with the outer core rod 121 with interior nib 121a, the top of lower floor's mould 12 is provided with and described interior the 3rd coaxial tap hole 121b of nib 121a, and three second tap holes 122 that run through lower floor's mould 12 upper and lower end faces, supply circulation road P2 for circulation road P1 from first tap hole 112 nib in the 3rd tap hole 121b constitutes to interior nib 121a from first tap hole 112 nib outside the outer nib 21 of second tap hole 122 to counterdie 2 constitutes.
