Abstract
The utility model discloses a kind of aluminum pipe extrusion die, including mold and lower mould, mould charging duct is offered on the mold, the lower mould the one side engaged with the mold offer with it is described on the lower mould stock chest that is engaged of mould charging duct, the side of the lower mould stock chest offers lower mold forming duct；Wherein, it is being round-like structure close to the lower mould stock chest opening position in the lower mold forming duct, remainder is cylindrical-shaped structure；The lower mold forming duct is being provided with alloy sleeve at the round-like structure.The utility model in lower mold forming duct due to being provided with alloy sleeve, so that the metallic aluminium after softening can be introduced into alloy sleeve under entrance behind mold forming duct, lower mold forming duct is protected by alloy sleeve, prevents lower mold forming duct from integrally ftractureing under high pressure, prevents mould from scrapping.
Description
Technical field
It the utility model is related to a kind of aluminum pipe extrusion die.
Background technology
In the prior art, the extrusion die of aluminium section bar is typically made up of die face and die-cushion two parts, die face and die-cushion it
Between it is generally assembled in a manner of surface is bonded and by fastening so as to forming a whole set of extrusion die.Generally, extrusion die needs to heat
Just start to extrude to 480 degree or so, aluminium alloy is molded by die working length at high temperature.In the process, the gold after softening
Belonging to aluminium can be molded as extruding behind the shaping duct of mould under entrance under, for a long time using easily causing die forming parts list
Facial cleft line or even overall cracking, so as to cause scrapping for mould.
Utility model content
The purpose of the utility model is that a kind of aluminum pipe extrusion die is provided the defects of presence for prior art.
The utility model to achieve the above object, adopts the following technical scheme that：A kind of aluminum pipe extrusion die, including mold
With lower mould, mould charging duct is offered on the mold, the lower mould is in the one side engaged with the mold
The lower mould stock chest being engaged with the upper mould charging duct is offered, the side of the lower mould stock chest offers lower mold forming
Duct；Wherein, it is being round-like structure close to the lower mould stock chest opening position in the lower mold forming duct, remainder is
Cylindrical-shaped structure；The lower mold forming duct is being provided with alloy sleeve at the round-like structure.
The beneficial effects of the utility model：The utility model makes due to being provided with alloy sleeve in lower mold forming duct
Metallic aluminium after must softening can be introduced into alloy sleeve under entrance behind mold forming duct, by alloy sleeve to lower mold forming duct
Protected, prevent lower mold forming duct from integrally ftractureing under high pressure, prevent mould from scrapping.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Shown in Fig. 1, it is related to kind of an aluminum pipe extrusion die, including mold 2 and lower mould 1, is offered on the mold 2
Upper mould feeds duct 21, the lower mould 1 one side engage with the mold 2 offer with it is described on mould feed duct
The 21 lower mould stock chests 11 being engaged, the side of the lower mould stock chest 11 offer lower mold forming duct 12；Wherein, described
Lower mold forming duct 12 is being round-like structure close to the lower opening position of mould stock chest 11, and remainder is cylindrical-shaped structure；
The lower mold forming duct 12 is being provided with alloy sleeve 13 at the round-like structure.
In use, the metallic aluminium after softening feeds duct 21 by upper mould and enters mould, subsequently into lower mould stock chest 11,
Enter lower mold forming duct 12 finally by alloy sleeve 13, until aluminum pipe is prevented lower mold forming duct by alloy sleeve
Shield, prevents lower mold forming duct from integrally ftractureing under high pressure, prevents mould from scrapping.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
