Abstract
The invention discloses a multi-hole parallel flow pipe extrusion die. The multi-hole parallel flow pipe extrusion die comprises an upper die and a lower die, wherein the upper die is provided with a die core, the front end of the die core is provided with a needle rod, a die core buffering part is connected with the needle rod, the rear end of the buffering part is provided with a die core base part, and the die core buffering part is of a wedge structure contracting from the die core base part to the needle rod. According to the multi-hole parallel flow pipe extrusion die provided by the invention, the die core is provided with the die core buffering part which is transitive from the mold core base part to the needle rod, the shock of the semi-molten aluminium alloy material to the needle rod is avoided, the service life of the die is prolonged, and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of metal pipe material production mould, particularly relate to a kind of porous-parallel stream pipe extrusion die.
Background technology
Porous-parallel stream pipe is car condenser tubing commonly used, and the condenser of flat flow structure or evaporimeter have advantages of that volume is little, lightweight, heat exchange performance is good.The concurrent flow pipe is generally continuous extrusion production, and aluminium is heated to send cooling forming by extrusion die after the fritting state.Extrusion die commonly used comprises upper die and lower die, counterdie is provided with outer forming cavity, and patrix is provided with formation die core, and the front end of core rod is porous, shaped needle bar, the endoporus aperture is less producing, during the more concurrent flow pipe of interior hole count, needle bar also can be thinner, and needle bar quantity also can increase, under the continuous impact of aluminum alloy materials to needle bar of fritting state, easily at needle bar root fracture, die life is short, and corresponding production cost is higher.
Summary of the invention
The purpose of this invention is to provide a kind of porous-parallel stream pipe extrusion die, when solving production small-bore many endoporus concurrent flow pipe, the easy fracture of needle bar, die life is short, the problem that production cost is high.
Technical scheme of the present invention is such: a kind of porous-parallel stream pipe extrusion die, comprise upper die and lower die, it is characterized in that, described patrix is provided with core rod, described die core front end is provided with needle bar, what be connected with needle bar is the core rod buffer part, and core rod buffer part rear end is the core rod base portion, and described core rod buffer part is the wedge structure that is shunk to needle bar by the core rod base portion.
In a specific embodiment of the present invention, described core rod buffer part and needle bar Length Ratio L1:L2 are 3:1.
In another specific embodiment of the present invention, described core rod base portion is provided with buckle, core rod and patrix clamping.
The advantage of technical scheme provided by the present invention is, arrange by the core rod buffer part of core rod base portion to the needle bar transition on core rod, make the aluminum alloy materials of fritting state flow to needle bar and not direct striker pin nose along buffer part, avoided impacting the impact of needle bar root has been caused the needle bar fracture, extended die life, core rod is that dismountable buckle is connected with patrix simultaneously, when the core rod damage needs to change, can change separately core rod, and need not change a whole set of mould, reduced production cost.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is core rod and patrix clamping schematic diagram.
The specific embodiment
The invention will be further described below in conjunction with embodiment, but not as a limitation of the invention.
See also Fig. 1, porous-parallel stream pipe extrusion die, comprise patrix 1 and counterdie 2, patrix 1 is connected with counterdie and is screwed connection, is provided with feed cavity 11 in patrix 1, be provided with outer forming cavity 21 in counterdie 2, wherein patrix 1 is provided with core rod 3, and core rod 3 front ends are provided with needle bar 4, and what be connected with needle bar 4 is core rod buffer part 31, core rod buffer part 31 rear ends are core rod base portion 32, and core rod buffer part 31 is the wedge structures that shunk to needle bar 4 by core rod base portion 32.Aluminum alloy materials is heated to the feed cavity 11 that flows into patrix 1 after the fritting state, is cooled to tubing after sending in the gap of core rod 3 and the outer forming cavity 21 of counterdie 2.
During circular hole concurrent flow pipe, core rod buffer part 31 length are made as 3mm in producing, and needle bar 1 length is set to 1mm.See also Fig. 2, in order to reduce to change the production cost increase that mould brings, core rod base portion 32 is provided with buckle 33, core rod 3 and patrix 1 clamping when core rod 3 damages, can be replaced separately core rod 3 like this, and need not replace whole patrix 1, when producing the concurrent flow pipe of different endoporus specifications, also only need to get final product with changing different core rod 3 equally, reduced production cost.
Claims (3)
