Description

The subway extruding die for aluminum shaped material

Technical field:

The utility model relates to a kind of mould, is specifically related to a kind of subway extruding die for aluminum shaped material.Belong to the mold machining technology field.

Background technology:

Along with the demand of market development, the large-tonnage extruder is also more and more, and particularly the demand of subway extruding die for aluminum shaped material is also more and more to big specification mould, but there are many deficiencies in the mould of at present big specification, as:

1, the tap hole on patrix next door is the same big with middle tap hole, can not guarantee the equilibrium of metal flow;

2, straight wall-like structure is adopted in counterdie seam chamber, can not adjust the flow rate of metal under the tap hole, therefore can not satisfy the feed requirement of section bar reinforcement;

3, straight wall-like structure is adopted in counterdie seam chamber, and the core rod on next door also adopts straight wall-like structure, and the intensity of core rod can not get guaranteeing.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of metal flow equilibrium is provided, and can satisfy the feed requirement of section bar reinforcement, can guarantee the subway extruding die for aluminum shaped material of core rod intensity again.

The purpose of this utility model is achieved in that a kind of subway extruding die for aluminum shaped material, form by upper and lower die combination, be provided with bridge location in the middle of the described patrix, be connected with core rod under the bridge location, core rod and bridge location junction form bevel-type and tiltedly draw, and offer two row's tap holes on the patrix on core rod both sides altogether, and every row's tap hole has a plurality of, wherein Pang Bian tap hole is expanded to both sides, forms tap hole expansion place; Corresponding to the tap hole on the patrix, the corresponding position is concaved with a step seam chamber on the counterdie, and the mating surface place of bridge location and seam chamber sinks to forming bridge location sinking place, and the core rod of patrix inserts the die cavity of bottom, counterdie seam chamber, constitutes the whole die cavity of section bar.

The utility model subway extruding die for aluminum shaped material, described every row's tap hole has four, and two rows have eight.

Compare with existing mold, the utlity model has following advantage:

1, middle four tap holes of four tap holes in patrix next door are added both sides and are done suitably expansion more greatly, have guaranteed the equilibrium of metal flow;

2, owing to adopted step seam chamber, can adjust the flow rate of metal under the tap hole, satisfy the feed requirement of section bar reinforcement;

3, owing to adopted step seam chamber, the core rod of adding the next door adopts bevel-type tiltedly to draw protection, has guaranteed the intensity of core rod.

Description of drawings:

Fig. 1 is a general structure schematic diagram of the present utility model.

Fig. 2 is the A-A profile of Fig. 1.

Fig. 3 is a patrix structural representation of the present utility model.

Fig. 4 is a counterdie structural representation of the present utility model.

The specific embodiment:

Referring to Fig. 1～2, the utility model is the subway extruding die for aluminum shaped material, is combined by upper and lower mould 1,2.

Referring to Fig. 2,3, described patrix 1 intermediate radial is provided with bridge location 8, bridge location is connected with core rod 48 times, core rod 4 forms bevel-type with bridge location 8 junctions and tiltedly draws 10, described core rod 4 is provided with conduction hole 9, offer two row's tap holes 6 on the patrix 1 on core rod 4 both sides altogether, every row's tap hole 6 has four or five, and two rows have eight or ten.Wherein Pang Bian tap hole 6 forms tap hole expansion place 7 to the both sides expansion.

Referring to Fig. 2,4, corresponding to the tap hole on the patrix 16, the corresponding position is concaved with a step (secondary) the seam chamber 3 that cooperates with it on the counterdie 2, bridge location 8 sinks to forming bridge location sinking place 5 with the mating surface place of seam chamber 3, the core rod 4 of patrix inserts the die cavity 11 of 3 bottoms, counterdie seam chamber, constitutes the whole die cavity of section bar.

Claims
