Abstract
The utility model provides a special octagonal tube aluminum profile extrusion die. The special octagonal tube aluminum profile extrusion die comprises an upper die and a lower die, wherein the upper die comprises a deflector and a welding room; eight diversion bridges are spirally distributed on the deflector; eight diversion holes are formed among the eight diversion bridges; the welding room is arranged at the lower parts of the diversion holes; a diversion pit is formed on the lower die; a pre-formed hole having the same shape with the section of the special octagonal tube aluminum profile is machined on the diversion pit; and the lower part of the pre-formed hole is communicated with a lower die working zone. The special octagonal tube aluminum profile extrusion die provided by the utility model has the advantages of convenience for machining, simplicity in assembly as well as convenience for large-scale production and manufacturing; and a correct method is provided for designing dies of the type in the future.
Description
Technical field
The utility model relates to a kind of mould, particularly relates to the anistree pipe of a kind of abnormity extruding die for aluminum shaped material.
Background technology
At present, domestic do not have the identical theory of a cover for aluminium section bar extrudate mould from design, manufacturing, production, and all self-dependent experience of accumulating over a long period of each designer is carried out the aluminum alloy extrusion section bar Mould design.The existing mould of producing aluminium section bar mainly is made up of patrix and counterdie two parts, and during extrudate, the hydrostatic pressure of aluminium alloy in mould is less; Cause aluminium shape surface coarse; It is difficult to be shaped, and particularly the aluminium section bar of some cross section more complicated is managed aluminium section bar like special abnormity anise.
The utility model content
The technical problem that the utility model solved is to provide the anistree pipe of a kind of abnormity extruding die for aluminum shaped material, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize: the anistree pipe of a kind of abnormity extruding die for aluminum shaped material comprises upper die and lower die two parts; Said patrix is made up of deflector, seam chamber; On the said deflector in the shape of a spiral shape be distributed with eight shunting bridges; Form eight tap holes between eight shunting bridges, the seam chamber is arranged on the tap hole bottom, and said counterdie is provided with the water conservancy diversion hole; Be processed with on the water conservancy diversion hole and the identical preform hole of abnormity anistree pipe aluminium section bar cross sectional shape, the bottom in preform hole is connected with the counterdie work zone.
The width of the said shunting bridge of the utility model is 5.5～6.5mm, guides the flow direction of aluminium alloy through the design to the patrix tap hole, has guaranteed speed and flow basically identical that aluminium alloy flows to all directions.The said amplification reserve of loft cut lengths down is 0.1～1.5mm, through to the control of loft cut lengths amplification reserve down, has guaranteed still to conform to quality requirements after product causes change in size owing to expanding with heat and contract with cold.Said counterdie work zone is identical with the cross sectional shape of the anistree pipe of abnormity aluminium section bar, and through the control to counterdie work zone length, has guaranteed the speed basically identical of all places of aluminium section bar when mould pushes out, thereby guarantees the size conforms quality requirement of product.
Beneficial effect: the utility model is easy to process, and assembling is easy, and is convenient to the large-scale production manufacturing, for the mould design of the type later on provides correct method.

Fig. 2 is the structural representation of the patrix of the utility model.
Fig. 3 is the structural representation of the following loft cutting of the utility model.
Fig. 4 is the structural representation of the counterdie work zone of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Fig. 1～4; The anistree pipe of a kind of abnormity extruding die for aluminum shaped material comprises patrix 1 and counterdie 2 two parts; Said patrix 1 is made up of deflector, seam chamber, on the said deflector in the shape of a spiral shape be distributed with between 3, eight shunting bridges 3 of eight shunting bridges and form eight tap holes 4; The seam chamber is arranged on tap hole 4 bottoms; Said counterdie 2 is provided with the water conservancy diversion hole, is processed with on the water conservancy diversion hole and the identical preform hole of abnormity anistree pipe aluminium section bar cross sectional shape, and the bottom in preform hole is connected with counterdie work zone 6.
The width of the said shunting bridge 3 of the utility model is 5.5～6.5mm, guides the flow direction of aluminium alloy through the design to the patrix tap hole, has guaranteed speed and flow basically identical that aluminium alloy flows to all directions.The amplification reserve that said loft down cuts 5 sizes is 0.1～1.5mm, through the control that following loft is cut 5 size amplification reserves, has guaranteed still to conform to quality requirements after product causes change in size owing to expanding with heat and contract with cold.Said counterdie work zone 6 is identical with the cross sectional shape of the anistree pipe of abnormity aluminium section bar; And through control to counterdie work zone 6 length; Guarantee aluminium section bar all places speed basically identical when mould pushes out, thereby guaranteed the size conforms quality requirement of product.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
Claims (4)
