Abstract
The utility model discloses a hot extrusion die with an improved structure. The hot extrusion die comprises an upper die and a lower die which are stacked on each other and connected together back and forth; a guide plate is arranged at the feeding end of the upper die; a plurality of bridge sites are formed on the guide plate and dividing holes are formed between the bridge sites; the lower die is provided with a welding cavity and a discharge hole which are communicated with each other from the feeding end to the discharge end; the welding cavity is communicated with the dividing holes of the upper die; the core print of the upper die is inserted in a forming hole of the lower die; the bridge sites of the upper die are extended in a curved line in the radial direction of the upper die. The hot extrusion die is characterized in that the bridge sites of the upper die are designed into a curved structure, a material going into the dividing holes goes into the welding cavity via the dividing holes arranged in a curved line shape, and the material is formed into a turbulent flow in the welding cavity so that the material flowing into the welding cavity from all the dividing holes is mixed thoroughly, and after the material is formed into a product by use of the forming hole, a welding line on the surface of the product is also extended in a spiral curved line manner; the hot extrusion die is high in overall strength, and small in cracking and damaging possibility during bending, cold drawing and stretching.
Description
Technical field
The utility model relates to a kind of extrusion die, particularly a kind of hot-extrusion mold of architecture advances.
Background technology
Various product mouldings are all realized by hot-extrusion mold, general hot-extrusion mold is made up of upper die and lower die, patrix is provided with deflector and core print, deflector is provided with bridge location, material enters in mould after the tap hole between each bridge location is shunted, then flow into seam chamber, enter conflux behind seam chamber, and then enter and in the molding space being formed by core print and forming hole, carry out extrusion modling, finally discharge from discharge opening, common bridge location is linear pattern along patrix radial direction at present, material enters seam chamber along tap hole, material enters moulding in forming hole after the indoor conflux of seam, but because bridge location is linear, material enters seam chamber along tap hole direct current, material in each tap hole is difficult to good seam, the product surface of moulding will produce linear pattern seam line along its length, so just affect the intensity of product, product in use easily occurs that cracking damages.
Utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of hot-extrusion mold of architecture advances, and the hot-extrusion mold of this architecture advances is simple in structure, material after tap hole shunting in the seam of seam indoor turbulence, on product, seam line is curved along its length, has improved the intensity of product.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of hot-extrusion mold of architecture advances, comprise can before and after the upper die and lower die that link together of stack, patrix feed end is provided with deflector, deflector is provided with some bridge locations, between each bridge location, form tap hole, counterdie is provided with seam chamber and the discharge opening of connection successively to discharge end from feed end, described seam chamber is communicated with the tap hole of patrix, the core print of patrix is inserted in the forming hole of counterdie, and each bridge location of described patrix extends along the curved state of patrix radial direction.
As further improvement of the utility model, each bridge location of described patrix is serpentine structure along patrix radial direction.
As further improvement of the utility model, the seamed edge of described each bridge location is equipped with fillet.
As further improvement of the utility model, described each bridge location cross section is positioned at discharge end one side and is the middle sharp structure of shrinking of two side direction along its thickness direction.
The beneficial effects of the utility model are: the bridge location of patrix is designed to curved configuration by the utility model, the material that enters tap hole enters seam chamber through curved tap hole, material forms turbulent flow in the indoor meeting of seam, make the indoor abundant seam of material of inflow seam in each tap hole, the seam line of the product surface of material after forming hole moulding also extends with regard to the mode that is helical curve, its bulk strength is high, damage not easy to crack in the time of bending, cold-drawn and stretching.

Detailed description of the invention
Embodiment: a kind of hot-extrusion mold of architecture advances, comprise can before and after the stack patrix 1 and the counterdie 2 that link together, patrix 1 feed end is provided with deflector, deflector is provided with some bridge locations 3, between each bridge location 3, form tap hole 4, counterdie 2 is provided with seam chamber 5 and the discharge opening 6 of connection successively to discharge end from feed end, described seam chamber 5 is communicated with the tap hole 4 of patrix 1, the core print of patrix 1 is inserted in the forming hole of counterdie 2, each bridge location 3 of described patrix 1 extends along the curved state of patrix 1 radial direction, material is in the tap hole 4 of patrix 1 flow into the seam chamber 5 of counterdie 2, because the bridge location 3 of patrix 1 is curved, tap hole 4 is also corresponding curved configuration, material flows into the interior formation turbulent flow in seam chamber 5 along the tap hole 4 of curve, good through turbulent material admixture, seam line after moulding on product is the linear extension of helical curve along product length direction, improve the intensity of product, product is damage not easy to crack in use.
Each bridge location 3 of described patrix 1 is serpentine structure along patrix 1 radial direction, serpentine structure can ensure that material enters the interior turbulence intensity in seam chamber 5, ensures material interior abundant fusion in seam chamber 5, can certainly be waveform, circular arc, bends linear etc.
The seamed edge of described each bridge location 3 is equipped with fillet.
Described each bridge location 3 cross sections are positioned at discharge end one side and are the middle sharp structure of shrinking of two side direction along its thickness direction, this just makes the aperture of tap hole 4 increase gradually to discharge end from feed end, strengthen flow, improved the turbulent flow of material, ensured that its seam is good.
