Abstract
The utility model discloses a shell aluminium profile extrusion die which comprises an upper die and a lower die, wherein a guide plate is arranged on the feed surface of the upper die; six divergent bridges are spirally distributed on the guide plate; six divergent holes are formed among the six divergent bridges; welding chambers are arranged on the feed surface of the lower die; guide pits are also arranged on the lower die; preformed holes with the same shapes as the sections of shell aluminium profiles are processed on the guide pits; and the lower parts of the preformed holes are communicated with lower die working tapes. The die disclosed by the utility model is convenient to process, easy to assemble and convenient to manufacture in a large scale, and provides a correct method for later design of such kind of dies.
Description
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of shell 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; Shaping difficulty, the particularly aluminium section bar of some cross section more complicated are like special special-shaped shell aluminium section bar.
The utility model content
The technical problem that the utility model solved is to provide a kind of shell 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: a kind of shell extruding die for aluminum shaped material comprises upper die and lower die two parts; Said patrix charging face is provided with deflector; On the said deflector in the shape of a spiral shape be distributed with six shunting bridges; Form six tap holes between six shunting bridges, said counterdie charging face is provided with the seam chamber, also is provided with the water conservancy diversion hole on the said counterdie; Water conservancy diversion is processed with the preform hole identical with shell aluminium section bar cross sectional shape on the hole, and the bottom in preform hole is connected with the counterdie work zone.
Step control stream is adopted in said seam chamber, and the seam outside is 18～22mm deeply, and the seam chamber interior is 28～32mm deeply.The width of said shunting bridge 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 0.1～2.0mm, 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 shell aluminium section bar, and through to the control of 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.

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. 1～5, a kind of shell extruding die for aluminum shaped material comprises patrix 1 and counterdie 2 two parts, and said patrix 1 charging face is provided with deflector; On the said deflector in the shape of a spiral shape be distributed with six shunting bridges 3; Form six tap holes 4 between six shunting bridges 3, said counterdie 2 charging faces are provided with the seam chamber, also are provided with the water conservancy diversion hole on the said counterdie 2; Water conservancy diversion is processed with the preform hole identical with shell aluminium section bar cross sectional shape on the hole, and the bottom in preform hole is connected with counterdie work zone 8.
Step control stream is adopted in said seam chamber, and seam outside 5 is 18～22mm deeply, and seam chamber interior 6 is 28～32mm deeply.The width of said shunting bridge 3 is 5.5～6.5mm, guides the flow direction of aluminium alloy through the design to patrix tap hole 4, has guaranteed speed and flow basically identical that aluminium alloy flows to all directions.The amplification reserve that said loft down cuts 7 sizes is 0.1～2.0mm, through the control that following loft is cut 7 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 8 is identical with the cross sectional shape of shell aluminium section bar, and through to the control of counterdie work zone 8 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.
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.
