Abstract

The utility model relates to a porous-type aluminium profile extrusion die. The porous-type aluminium profile extrusion die is formed by overlapping an upper die and a lower die in front-back direction, wherein a first boss (1) is formed in the center of the feeding surface of the upper die, four second bosses (2) are uniformly distributed at the periphery of the first boss (1), the first boss (1) and the second bosses (2) are hemispherical, four shunt bridges (3) are uniformly distributed at the periphery of each second boss (2), four tap holes (4) are formed among the four shunt bridges (3), four die cores (5) are arranged on the discharge surface of the upper die, positions of the four die cores (5) correspond to the positions of the four second bosses (2) in the feeding surface of the upper die, four seaming chambers (6) are arranged on the feeding surface of the lower die, each seaming chamber (6) is petaloid, and the center of the four seaming chambers (6) corresponds to the positions of the four die cores (5). The porous-type aluminium profile extrusion die is relatively low in extrusion pressure and can realize rapid extrusion, and production efficiency is greatly improved.

Description

The porous type extruding die for aluminum shaped material

Technical field

The utility model relates to a kind of porous type extruding die for aluminum shaped material, belongs to the aluminium section die technical field.

Background technology

Extruding die for aluminum shaped material in the past is all to take the single hole Design of Dies as main, so that the workshop produced on-site operates and repairs a die.But, along with the fast development of Aluminum, the production of a high flow rate can not form competitiveness, can only could meet the industry development needs by High-efficient Production.Multiple-hole die design immediately constantly occurs, still all fails to reach desirable poised state, and its squeeze pressure is larger, and extrusion speed is slow, and production efficiency is low, and distortion is large, the front and back discharging is unstable, therefore fails to be popularized.

summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of porous type extruding die for aluminum shaped material is provided, and its squeeze pressure is less, can realize crushing failure at high speed, has greatly improved production efficiency.

The purpose of this utility model is achieved in that a kind of porous type extruding die for aluminum shaped material, it is formed by stacking by before and after upper die and lower die, described patrix charging face center is provided with the first boss, be evenly equipped with four the second boss around described the first boss, described the first boss and the second boss are hemispherical, be evenly equipped with four shunting bridges around each second boss, form four tap holes between four shunting bridges, described patrix goes out on charge level to be provided with four core rods, the position of described four core rods is corresponding with the position of four the second boss on patrix charging face, be provided with four seam chambers on described counterdie charging face, described seam chamber is petal-shaped, center, described four seam chambers is corresponding with four core rod positions.

Compared with prior art, the utlity model has following beneficial effect:

A kind of porous type extruding die for aluminum shaped material of the utility model, its patrix goes out charge level and has been evenly arranged four core rods, four core rod correspondence positions of patrix charging face and four core rod centers are provided with hemispheric boss, can play the effect of supporting and shunting, can reduce the rubbing action of aluminium material and mould, the aluminium material more easily enters in the tap hole of boss surrounding, and its squeeze pressure is smaller simultaneously, can realize crushing failure at high speed, greatly improve the production efficiency of aluminium section bar.
