Technical field
The utility model belongs to hot-extrusion mold technical field, and more particularly to a kind of hot extrusion positive pressure squeezes big pipe divergent die
Tool.
Background technology
Because aluminium extrusion product processing characteristics is good, light quality, the superiority of exquisite appearance, while also because aluminium alloy extruded
Technology is gradually improved, and various buildings, industrial aluminium alloy product also arises at the historic moment.Hot extrusion positive pressure squeezes great circle pipe mold
It is many that scrappage is higher than common die, and, the performance of great circle pipe profile also more difficult satisfaction, is to solve problem above, is improved
Aluminium section bar productivity effect, improves die quality and production capacity is particularly important.
Utility model content
The purpose of this utility model is to provide a kind of hot extrusion positive pressure and squeezes big pipe divergent die tool, and mould stress in reduction is reduced
Mould is damaged, and extends die life.Reduce influence of the aluminium bar slag inclusion to surface of extruded profiles.
The technical scheme of use is：
A kind of hot extrusion positive pressure squeezes big pipe divergent die tool, including deflector, upper die and lower die, it is characterised in that：

Fasten, offer multiple holes for hoist respectively on deflector, the outer wall of upper die and lower die, deflector and upper mould pass through the first screw thread
Attachment screw connection in hole, upper die and lower die are connected by the attachment screw in the second screwed hole, between deflector and upper mould
The first alignment pin is provided with, the second alignment pin is provided between upper die and lower die.
Circumference offers eight pod apertures on the deflector and upper mould, and each pod apertures section is bellmouth, and phase
Shunting bridge is formed between two adjacent pod apertures, relief groove is offered on the inwall of each pod apertures, feeding mouth depressurizes, reduced
Die pressure, improves mould production capacity.The charging end face of the deflector is upper to be provided with annular groove at pod apertures by heavy bridge,
Higher than at pod apertures, the discharging end face of the deflector is circular arc, the discharging of deflector for the center and edge of deflector
The charging end contact at the edge of end face and upper mould, the center of discharging end face of deflector and the charging end face of upper mould have a spacing
From.The center of the core rod of the upper mould offers heat treatment hole, contributes to thicker die ＆ mold treatment fully, improves steel
Can, extend steel service life.Upper die and lower die are fastened and are formed with annular hole.
Discharge opening is offered on the lower mould, two grades of empty knives, the charging end face of lower mould are offered on the inwall of discharge opening
Bonding container is offered, the lower end positioned at bonding container on the inwall of discharge opening offers two grades of bonding containers, in the bottom surface of bonding container
A groove above and at each shunting bridge is offered, the inwall of each groove is inclined-plane, and bonding container and two grades of bonding containers lead to
Cross groove connection.
The advantage is that：The upper mould stress of this mould reduction, reduces mould and damages, and extends die life.Reduce aluminium bar slag inclusion
Influence to surface of extruded profiles.By the interaction of bonding container and two grades of bonding containers, it is to avoid the generation of cul de sac area of mold, make type
Material various pieces discharging speed is identical.
