Abstract

The utility model discloses an extrusion die for a hollow aluminum profile. The extrusion die comprises a lower die, an upper die covering the lower die and a die core arranged between the upper and lower dies. An even number of flow division holes are uniformly distributed around the upper die. Two central flow division holes are formed at the central position of the upper die. A firs flow division bridge is arranged between the central flow division holes. A first sunken bridge is arranged below the first flow division bridge. Lug bosses are arranged below the central flow division holes. Compared with the prior art, the extrusion die has the advantages that a die breakage or deflection phenomenon can be avoided, the die is strong in strength, and the machining efficiency of the hollow aluminum profile can be improved.

Description

The hollow aluminum profile extrusion die
Technical field
The utility model relates to a kind of hot-extrusion mold, is specifically related to a kind of hollow aluminum profile extrusion die.
Background technology
Aluminium has extrusion molding property preferably, has light specific gravity, intensity is good, and so advantages such as good economy, the feature of environmental protection and recuperability are aluminium extensive use and technical fields such as industry, decoration.Present stage aluminium section bar processing, be to accomplish mostly, for aluminium section bar with more hollow-core construction through hot-extrusion mold; There is the use defective in existing hot-extrusion mold, and concrete is, because patrix core rod undercapacity; When producing, occur mould fracture or beat phenomenon easily, sky appears dragging in hollow-core construction place feed difficulty easily; And because of mould strength is not enough, production efficiency is lower.
The utility model content
To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of hollow aluminum profile extrusion die, and it can avoid the phenomenon of mould fracture, beat, the production efficiency of raising hollow aluminum section bar.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The hollow aluminum profile extrusion die; Comprise counterdie, cover the patrix on the counterdie and be installed in the core rod between the upper die and lower die; Be evenly distributed with the even number tap hole around the patrix, the patrix centre position is provided with two mid-tap holes, is provided with the first shunting bridge between the two mid-tap holes; The below of the first shunting bridge is provided with the first heavy bridge, and mid-tap hole below is provided with boss.
Be provided with the second shunting bridge between the two adjacent tap holes, the below of the second shunting bridge is provided with the second heavy bridge.
The upper surface of counterdie is provided with a step-like seam chamber.
The beneficial effect of the utility model is:
Than prior art, the utility model can be avoided existing mould fracture or beat phenomenon, and mould strength is higher, can improve the working (machining) efficiency of hollow aluminum section bar.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the cutaway view of Fig. 1;
Wherein: 1, patrix; 11, tap hole; 12, shunting bridge; 13, heavy bridge; 14, mid-tap hole; 15, shunting bridge; 16, heavy bridge; 17, boss; 2, counterdie; 21, seam chamber; 3, core rod.
The specific embodiment
Below, in conjunction with the accompanying drawing and the specific embodiment, the utility model done further describing:
Like Fig. 1, shown in 2; Be a kind of hollow aluminum profile extrusion die of the utility model, it comprise counterdie 2, cover the patrix 1 on the counterdie 2 and be installed in patrix 1 and counterdie 2 between core rod 3, be evenly distributed with even number tap hole 11 around the patrix 1; Patrix 1 centre position is provided with two mid-tap holes 14; Be provided with shunting bridge 15 between the two mid-tap holes 14, the below of shunting bridge 15 is provided with heavy bridge 16, and mid-tap hole 14 belows are provided with boss 17.Tap hole 11 evenly distributes at the periphery of patrix 1, can control the labor and materials flow, makes mould inner pressure even, reduces the pressure of labor and materials to mould; Shunting bridge 15 between the two mid-tap holes 14, heavy bridge 16 are used to guarantee mould strength; Boss 17 can be controlled the labor and materials flow, guarantees core rod 3 feed are prevented and drag sky, beat phenomenon.
Be provided with shunting bridge 12 between the two adjacent tap holes 11, the below of shunting bridge 12 is provided with heavy bridge 13, has further increased the intensity of mould, improves die life, guarantees the stability of aluminium section bar; The upper surface of counterdie 2 is provided with a step-like seam chamber 21, and the labor and materials seam time can be controlled in step-like seam chamber 21, strengthens intensity of aluminum alloy.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
