Description
Technical field
The utility model relates to a kind of tube and pipe of aluminium alloy porous extrusion molding dies.
Background technology
China's aluminium section bar industry is great development from 20th century the mid-80s, and the initial market demand is from common door window profile, progressively expands to large-scale curtain wall profiles, household section bar, sanitaryware etc.Section material section is also ascending, from simple to complex.
Extruding die for aluminum shaped material is in the past all based on single hole Design of Dies, so that plant site production operation and repairing 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 industry development needs by High-efficient Production.Multiple-hole die design immediately constantly occurs, but all fails to reach desirable poised state, and its squeeze pressure is comparatively large, and extrusion speed is slow, and production efficiency is low, and distortion is large, front and back discharging is unstable, is therefore popularized.Tube and pipe of aluminium alloy porous extrusion die has production high efficiency, advantage that production cost is low, but the shortcoming of flow velocity inequality between ubiquity porous, the problem that divergent die die size is easily overproof.
Utility model content
For there being the defect of technology on overcoming, it is less that the purpose of this utility model is intended to propose a kind of squeeze pressure, can realize the tube and pipe of aluminium alloy porous extrusion molding dies of crushing failure at high speed.
For achieving the above object, the utility model adopts following technical scheme:
A kind of tube and pipe of aluminium alloy porous extrusion molding dies, is characterized in that: comprise patrix, deflector and counterdie; Described patrix is evenly provided with four charging holes, the barycenter of four charging holes is circumferentially same; Be provided with shunting bridge between each charging hole described, shunting bridge and charging hole are for being intervally arranged, and the barycenter of each shunting bridge is circumferentially same; The center of described patrix is provided with the core rod of discharging; Described counterdie is provided with bonding container; Described shunting bridge is that X bridge is arranged; Described patrix thickness is less than counterdie thickness; The front end of described charging hole is provided with chamfering.
Explanation and the further scheme of such scheme are as follows:
In such scheme, the shape of described charging hole is heart-shaped.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The tube and pipe of aluminium alloy porous extrusion molding dies that the utility model provides, its squeeze pressure is less, can realize crushing failure at high speed, substantially increase production efficiency, reduces the production cost of product, improves the competitiveness of product in market.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model patrix;
Fig. 2 is the structural representation after this realizes novel middle patrix counterdie matched moulds.
In above accompanying drawing: 1, patrix; 2, counterdie; 3, charging hole; 4, bridge is shunted; 5, core rod; 6, bonding container.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: shown in Fig. 1-Fig. 2:
A kind of tube and pipe of aluminium alloy porous extrusion molding dies, comprises patrix 1, deflector and counterdie 2; Described patrix 1 is evenly provided with the barycenter of four charging holes, 3, four charging holes 3 circumferentially same; Be provided with shunting bridge 4 between each charging hole 3 described, shunting bridge 4 is with charging hole 3 for being intervally arranged, and the barycenter of each shunting bridge 4 is circumferentially same; The center of described patrix 1 is provided with the core rod 5 of discharging; Described counterdie 2 is provided with bonding container 6; Described shunting bridge 4 is arranged in X bridge; Described patrix 1 thickness is less than counterdie 2 thickness; The front end of described charging hole 3 is provided with chamfering; The shape of described charging hole 3 is heart-shaped.
Shunting bridge in mould adopts X bridge to arrange, reduces the flow velocity inequality because extruder bias causes; Charging hole adopts heart-shaped, mainly makes aluminium material better toward dead band flowing under bridge, balancing die flow velocity; Chamfering is carried out in charging hole front end, reduces aluminium material to the impulsive force of mould, thus reduces die deformation, make production more stable; Reduce patrix thickness, reduce the friction between aluminium material and mould, reduce to heat up, thus improve extrusion speed to greatest extent.
The utility model is by optimizing the setting of upper and lower mould, and impel stephanoporate round tube mould flow velocity balance between porous, product stablizes zero deflection.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model change or modify, and all should be encompassed within protection domain of the present utility model.
