Abstract
The utility model discloses an aluminum sectional material hot extrusion mold, which is formed by an upper mold and a lower mold through overlapping, wherein four unequal flow dividing holes are uniformly distributed on the circumference of the feeding surface of the upper mold, two center flow dividing holes are formed in the middle, a plurality of mold cores are arranged in the center of the material discharge of the upper mold, a welding chamber and a die cavity are arranged on the feeding surface of the lower mold, a hollow cutter is arranged on the material discharge hole wall of the material discharge surface, a flow blocking lug boss is convexly arranged at an inner die cavity part of a welding chamber and is in an opening ring shape, and a tearing strip is arranged at the opening part of the flow blocking lug boss. The aluminum sectional material hot extrusion mold has the advantages that openings of extruded products become sealing openings of the tearing strip, after the extruded material discharge sectional materials are tensioned and straightened, the head and tail dimensions are completely controlled in the tolerance range, in the use process in subsequent work procedures, only the sealing openings with the tearing strip need to be torn, and the dimension cannot be obviously changed, so the aluminum sectional material deep groove opening dimension can be stabilized, the deformation avoidance in the subsequent tensioning straightening process can be ensured, the finished product rate is improved, and the development of the aluminum sectional material industry is promoted.
Description
Technical field
The utility model relates to a kind of hot-extrusion mold, relates in particular to a kind of aluminium section hot-extrusion die, belongs to the aluminium section bar processing technique field.
Background technology
Along with the develop rapidly of science and technology, the application of aluminium alloy industry profile more and more widely, the kind of section bar is more and more, and its surface quality and required precision are also more and more higher, this just has higher requirement to Mould design and processing.
Aluminium section bar manufacturer produces some dark slot opening section bars through regular meeting; its opening size tolerance is minimum; and these opening sizes all are the assembling sizes; if can not guarantee; the quality of product will directly be influenced; influence the serviceability of product; and the dimension precision requirement of the dark slot opening of the very difficult assurance of the mould of conventional design now; even the deep trouth opening is in size public relations scope when discharging, follow-up tension straingtening also can make opening dwindle, and causes the super lower limit of size; and owing to head and the tail dimension of section bar differs greatly; often can not take into account mutually in the extrusion process, cause the finished product rate low, hinder the aluminium section bar industrial expansion.
The utility model content
At above-mentioned defective, the utility model provides a kind of aluminium section hot-extrusion die, can stablize the dark slot opening size of aluminium section bar, guarantees in follow-up tension straingtening indeformablely, improves the finished product rate, promotes the aluminium section bar industrial expansion.
To achieve these goals, the technical scheme that adopts of the utility model is:
A kind of aluminium section hot-extrusion die, be formed by stacking by upper die and lower die, four of the charging face circumference uniform distributions of patrix do not wait tap hole, the centre arranges two center tap holes, four do not wait tap hole be distributed on two center tap holes around, the charge level center that goes out of patrix is provided with several core rods, the charging face of described counterdie is provided with seam chamber and die cavity, the discharging hole wall that goes out charge level is provided with the sky cutter, protrude and be provided with the choked flow boss at the indoor die cavity of described seam place, described choked flow boss is the opening ring-type, and this choked flow boss openings place is provided with tear strip.
Further, adjacent neither the grade is provided with the shunting bridge between the tap hole, and the shunting bridge is arranged with heavy bridge.
Aluminium section hot-extrusion die of the present utility model, make the opening of extruded product become the close mouth that has tear strip, extruding and discharging section bar drawn aligning occiput, tail dimension are controlled fully within the margin of tolerance, when subsequent handling is used only the city close mouth that needs to have tear strip tear and get final product, significant change can not take place in size, thereby stablizes the dark slot opening size of aluminium section bar, guarantees in follow-up tension straingtening indeformable, improve the finished product rate, promote the aluminium section bar industrial expansion.

Fig. 2 is sectional structure schematic diagram of the present utility model.
Reference numeral: 1, patrix, 2, counterdie, 3, do not wait tap hole, 4, the center tap hole, 5, core rod, 6, the seam chamber, 7, die cavity, 8, empty cutter, 9, the choked flow boss, 10, tear strip.
The specific embodiment
The utility model is further described below in conjunction with specific embodiment.
As shown in Figure 1, aluminium section hot-extrusion die of the present utility model, be formed by stacking by patrix 1 and counterdie 2, four of the charging face circumference uniform distributions of patrix 1 do not wait tap hole 3, the centre arranges two center tap holes 4, four do not wait tap hole 3 be distributed on two center tap holes 4 around, the charge level center that goes out of patrix 1 is provided with several core rods 5, the charging face of described counterdie 2 is provided with seam chamber 6 and die cavity 7, the discharging hole wall that goes out charge level is provided with sky cutter 8, protrude and be provided with choked flow boss 9 at the die cavity place in the described seam chamber 6, and described choked flow boss 9 is the opening ring-type, and these choked flow boss 9 opening parts are provided with tear strip 10.
Adjacent neither the grade is provided with shunting bridge 11 between the tap hole 3, shunting bridge 11 is arranged with heavy bridge 12.Shunting bridge 11 and heavy bridge 12 play the effect that increases mould strength.
The above only is a kind of embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model know-why; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
Claims (2)
1. aluminium section hot-extrusion die, be formed by stacking by upper die and lower die, it is characterized in that: four of the charging face circumference uniform distributions of patrix do not wait tap hole, the centre arranges two center tap holes, four do not wait tap hole be distributed on two center tap holes around, the charge level center that goes out of patrix is provided with several core rods, the charging face of described counterdie is provided with seam chamber and die cavity, the discharging hole wall that goes out charge level is provided with the sky cutter, protrude and be provided with the choked flow boss at the indoor die cavity of described seam place, described choked flow boss is the opening ring-type, and this choked flow boss openings place is provided with tear strip.
