Abstract
The invention relates to a novel aluminum profile hot extrusion mould for a hand rail, which is mainly used for the hot extrusion of building hand rail profile. The mould comprises an upper mold (1) and a lower mold (2) which are overlaid front and rear, the feeding surface of the upper mold (1) is provided with five flow-dividing bridges (1.2), five flow-dividing holes (1.1) are formed among the five flow-dividing bridges (1.2), the middle flow-dividing hole shrinks from large to small, thus forming a large head and a small head, furthermore, the large head is arranged in the center of the feeding surface of the upper mold (1), and the hole is called a direct impact groove flow-dividing hole (1.1.1). The feeding surface of the lower mold (2) is provided with a welding chamber (2.1), the rear of which is provided with a mold cavity (2.3), and the middle of the mold cavity (2.3) is provided with a groove position (2.3.1) which is arranged directly below the large head end of the direct impact groove flow-separating hole (1.1.1). The bottom of the welding chamber (2.1) is provided with an arc-shaped flow-blocking plate (2.3) in an upward convex way along the cavity wall of the mold cavity (2.2). The mould ensures adequate feeding at the groove part of the mold cavity of the lower cavity and the uniform discharging of the extruded aluminum profile, without the problems of hand feeling and welding strips, etc.
Description
(1) technical field
The present invention relates to a kind of aluminium section hot-extrusion die.Be mainly used in the hot extrusion of Building rail handrail section bar.Belong to the mold machining technology field.
(2) background technology
Aluminum products have a series of good characteristics, and are good as intensity, against weather is good, density is little, easy extrusion molding etc.So aluminium section bar is widely used in building and industrial.Not only require shapeliness, outward appearance beautiful to the Building rail handrail at present, and durable.Accommodation rail is shaped as: a large semi-circular, centre are with a wide 12.7mm, the groove of dark 20.5mm, as shown in Figure 7.Produce at present this series products and often occur that surface quality is poor, shapeless, opening size is difficult to phenomenons such as assurance, section bar discharging inconsequent.Thereby production time and production cost have been increased greatly.Trace it to its cause, mainly be: tap hole charging face two ends are equally big in the middle of the patrix, and this tap hole departs from the certain distance in groove position of counterdie die cavity, make the groove feed abundance of counterdie die cavity, speed differs to making section bar produce distortion in the time of can extruding die cavity because of under feeding in the groove or aluminium material in extrusion process; Counterdie seam chamber is not provided with the choked flow platform, can not make the section bar surface problems such as feel or seam line occur because of seam is good in extrusion process.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of groove feed abundance that makes the counterdie die cavity is provided, makes the aluminium section bar discharging of extruding even, the novel hand-rail aluminium section hot-extrusion die of problems such as no feel, seam line.
The object of the present invention is achieved like this: a kind of novel hand-rail aluminium section hot-extrusion die, be formed by stacking by before and after the upper die and lower die,
Described patrix charging face is furnished with five shunting bridges, forms five tap holes between five shunting bridges, and a wherein middle tap hole shrinks from large to small gradually, form large and small head, and stub end places described patrix charging face center, is referred to as to fling the groove tap hole
Described counterdie charging face is provided with the seam chamber, and seam is provided with die cavity behind the chamber, have in the middle of this die cavity a groove position, this groove position be arranged at described patrix fling groove tap hole stub end under; Bottom, described seam chamber is along the described die cavity chamber wall arc choked flow platform that is provided with protruding upward.
Compare with existing similar mould, the present invention has following advantage:
The present invention is by putting an intermediate feed face and arrive the few tap hole of outside charging face greatly, gradually in that patrix being ad hoc over against the groove position of counterdie die cavity, and be provided with in the groove of the through counterdie die cavity of tap hole pan feeding, make the groove feed abundance of counterdie die cavity, speed does not differ to making section bar produce distortion in the time of can not extruding die cavity because of under feeding in the groove or aluminium material in extrusion process.All the other are provided with four tap holes on the patrix, with the die cavity feed around satisfying; The present invention by indoor in the counterdie seam be that the periphery of die cavity is provided with a boss (choked flow platform), the purpose one, guarantee the section bar surface quality, in extrusion process, can not make the section bar surface problems such as feel or seam line occur because of seam is not good.Two, further guarantee the feed abundance of section bar female screw hole.
Hand-rail aluminium section of the present invention is in extrusion process, after the process tap hole is shunted aluminium bar, allow counterdie groove position obtain sufficient aluminium material, enter the seam chamber then, flow to die cavity then in indoor stopping once more of seam through the choked flow platform, the aluminium section bar discharging of extruding is even to making, problems such as no feel, seam line.The present invention has solved the problem that accommodation rail shaping difficulty, groove opening size are difficult to guarantee fully.
