Description
(1) technical field
The utility model relates to a kind of aluminium section hot-extrusion die.Be mainly used in the hot extrusion of the big industry profile of multimode core.Belong to the mold machining technology field.
(2) background technology
The stability, persistence, the anti-wind pressure that have material owing to aluminum alloy extrusion section bar are good; Have the workability of section bar, easy maintenance and maintenance property; Have many advantages such as good and economic, the feature of environmental protection and recuperability.Therefore aluminum alloy extrusion section bar in the application of every field more and more widely.Now, at industrial circle, the various machine components that aluminum alloy extrusion section bar is made are used more and more.Wherein, many large-scale industrial extrudates are arranged, shape is very complicated, and tolerance is also very strict.The circumscribed circle of this section bar is big, and core rod is many, and intermediate ribs is many and longer, also has big cantilever, as Fig. 9.The mould of this section bar is when extruding, and it is difficult to be shaped, and the feed on both sides is difficult to guarantee that the feed of intermediate ribs is not enough easily, the easy beat of core rod, and cantilever ruptures easily, and the output of mould is not high, makes that the cost of section bar is very high.Tracing it to its cause, is because present preposition deflector of mould and patrix tap hole distribute very little and be unreasonable, can not fully guarantee the feed of counterdie two ends and intermediate ribs; The patrix core rod and the counterdie die cavity at the cantilever place, two places of section bar adopt unsettled design, have reduced the intensity of cantilever, have increased the risk that causes mould to scrap because of the cantilever beat.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can guarantee that the each several part feed is more even, prevents cantilever broke, can also significantly improve the hot-extrusion mold of the big industry profile of multimode core of output simultaneously.
The purpose of this utility model is achieved in that the hot-extrusion mold of the big industry profile of a kind of multimode core, comprises preposition deflector, upper die and lower die,
Described preposition deflector is provided with ten feed orifice altogether, and wherein middle have two feed orifice, and respectively there are three feed orifice on both sides, and respectively there is a feed orifice at two ends,
Described patrix charging face is provided with ten tap holes altogether, and wherein middle have two tap holes, and respectively there are three tap holes on both sides, respectively there is a tap hole at two ends, the downward protrusion was provided with core rod in the middle of patrix went out charge level, and a side of this core rod and the design of top end face intersection have the core rod splicing to face directly
Described counterdie charging face is provided with the seam chamber, seam is provided with die cavity behind the chamber, described die cavity is faced corresponding chamber wall part design directly with the core rod splicing of patrix has the die cavity splicing to face directly, this die cavity splicing is faced directly and faced directly when cooperating with the core rod splicing of patrix is seamless cooperation, form the straight mouth of piecing together, other mating surface of described die cavity and patrix core rod all leaves a wall thickness gap.
Preposition deflector of the utility model and patrix adopt the design of ten minutes feed orifice and ten tap holes respectively, can fully guarantee the feed of counterdie two ends and intermediate ribs like this.The effect of preposition deflector is the pre-distribution of carrying out the each several part feed, guarantees the uniformity and the abundance of each several part feed, can also play the effect of protection patrix simultaneously, improves the output of mould.Patrix intermediate section discharge orifice has guaranteed the feed of counterdie die cavity intermediate ribs, thereby has avoided core rod because of drawing the too many intensity reduction that causes that material is beaten, and has improved the intensity of core rod, has reduced the inclined to one side wall of section bar.The cantilever place, two places of section bar adopts two bridging type designs, has guaranteed the intensity of cantilever, has reduced the risk that causes mould to scrap because of the cantilever beat.
