Description
Technical Field
The utility model belongs to forge wheel hub mould and make the field, relate to a modified aluminum alloy wheel hub forges mould liftout structure.
Background
Forged hubs have been an important member of the aluminum alloy hub market all the time, and belong to middle and high-end products. As the name suggests, the forged hub is manufactured by adopting a forging process, and the core of the forging process is a forging process. The forging process comprises the steps of rotary forging, initial forging, final forging, hole expanding and punching, spinning and the like, wherein the three steps of final forging, hole expanding and punching and spinning are the most basic steps, and the steps can be increased according to the difficulty of the hub.
The most central tool for realizing hub forming in each forging step is a die, and the quality of the die directly influences the yield of a hub blank. The primary forging die and the final forging die mainly comprise an upper bottom plate, a lower bottom plate, an upper die holder, a lower die holder, an upper die core, a lower die core, an upper ejector, a lower ejector and the like, and the ejection of the die is realized by the ejector. The ejector is of a rotary structure and is arranged at the central part of the mold core. When the mold is opened, an oil cylinder of the equipment pushes the ejector to move, the wheel hub blank adhered on the mold is ejected out, and then the blank is conveyed away. Because the forging pressure is very large, namely 4000 tons for small forging and more than 9000 tons for large forging, the ejector is pressed and deformed by the high pressure, and the part of the ejector, which is in fit contact with the mold core, is deformed, so that the fit position of the ejector and the mold core is fixed; once the two parts are changed, the two parts cannot be perfectly matched, and the end surface of the ejector is not horizontal; when the condition occurs in the upper ejector, the condition that the surface of an end face forming part, namely a hub blank flange, is uneven can be caused, the hub positioning in the spinning step is the blank flange surface, the uneven blank surface can cause the hub blank positioning deviation, finally, the coaxiality of a hub rim formed by spinning can be reduced, the yield of subsequent machining is reduced, and the manufacturing cost of the hub is influenced. The reason for causing the position change of the ejector is that the ejector is of a revolving body structure, and the positions of mounting the ejector each time when the upper machine front mold is prepared are inconsistent because of no positioning structure; in addition, the ejector moves up and down in the forging work, and the position of the ejector can be changed due to different stresses of different working states of the die.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a modified aluminum alloy wheel hub forges mould liftout structure, this structure can the unset problem in mould use position of effectual solution liftout ware.
The technical scheme of the utility model is that: an improved ejecting structure of an aluminum alloy hub forging die comprises a bottom plate, a die core, a limiting block, an upper ejector, an anti-rotation ring, a positioning pin and a fixing bolt, wherein the upper ejector is of a revolving body structure, one side of the upper ejector is provided with a plane, and the cross section of the upper ejector is in a letter D shape; a round platform structure is processed at the front part of the middle of the mold core, and four pin holes and four threaded holes are arranged; the anti-rotation ring is of an annular structure, a plane is arranged on the inner vertical surface, the cross section is in a letter D shape, a chamfer is arranged on the inner side of the anti-rotation ring, the chamfer is larger than the chamfer of the upper ejector, four step holes are arranged on the side end surface of the chamfer, four blind pin holes are arranged on the other side end surface of the chamfer, and small through holes are arranged at the bottoms of the pin holes; the locating pin is the cylinder structure and one side is equipped with the screw hole. The positioning pin is arranged in pin holes of the mold core and the anti-rotation ring, the anti-rotation ring is arranged in a circular table groove of the mold core and is fixed through a bolt, and the upper ejector penetrates through the anti-rotation ring and is arranged at the central part of the mold core.
The utility model discloses simple structure because the rotating ring all is "D" shape structure with last ejector cooperation position, consequently goes up the unable rotation of ejector, and cooperation position between them is fixed. The structure can effectively solve the problem that the position of the upper ejector is not fixed in the use process of the die.

Detailed Description
As shown in fig. 1, the existing mold ejector structure comprises a bottom plate 1, a mold core 2, a limiting block 3 and an upper ejector 4, and the upper ejector 4 is of a revolving body structure, so that when a mold is prepared before the operation of a machine, the position for assembling the upper ejector 4 is not fixed, and the positions of the upper ejector 4 are different each time; in addition, the ejector 4 moves up and down in the forging work, and the position of the ejector can be changed due to different stresses of different working states of the die.
As shown in fig. 2, 3, 4 and 5, an improved aluminum alloy wheel hub forging die liftout structure comprises a bottom plate 1, a die core 2, a limiting block 3, an upper liftout device 4, an anti-rotation ring 5, a positioning pin 6 and a fixing bolt 7, wherein the upper liftout device 4 is of a revolving body structure, one side of the upper liftout device is provided with a plane, and the cross section of the upper liftout device is in a letter 'D' shape; a round platform structure is processed at the front part of the middle of the mold core 2, and four pin holes and four threaded holes are arranged; the anti-rotation ring 5 is of an annular structure, a plane is arranged on the inner vertical surface, the cross section is in a letter D shape, meanwhile, a chamfer is arranged on the inner side, the chamfer is larger than the chamfer of the upper ejector 4, the interference of the two chamfers is prevented, four step holes are arranged on the side end surface of the chamfer, fixing bolts 7 are installed in the four step holes, the other side end surface of the chamfer is provided with four blind pin hole installation positioning pins 6, and meanwhile, small through holes are arranged at the bottoms of the pin holes, so that the exhaust is convenient when; the locating pin 6 is cylindrical structure and one side is equipped with the screw hole, makes things convenient for locating pin 6 to dismantle. The positioning pin 6 is arranged in pin holes of the mold core 2 and the anti-rotation ring 5, the anti-rotation ring 5 is arranged in a circular table groove of the mold core 2 and is fixed through a bolt 7, and the upper ejector 4 penetrates through the anti-rotation ring 5 and is arranged at the central part of the mold core 2.
When the die is opened and unloaded, the press machine pushes the upper ejector 4 to move downwards, and the upper ejector 4 slides along the die core 2 and the anti-rotation ring 5 until the limiting block 3 is attached to the die core 2; during the mould closing process, the upper ejector 4 slides upwards along the anti-rotation ring 5 and the mould core 2 along with the downward movement of the upper part of the mould, which is pushed by the forged piece bar stock, until the mould is closed. Because the matching surfaces of the anti-rotation ring 5 and the upper ejector 4 are both in a D-shaped structure, the upper ejector 4 cannot rotate, and the matching positions of the anti-rotation ring and the upper ejector 4 are fixed.
The structure avoids the condition that the end face of the upper ejector is not level due to poor matching, the end face forming part, namely the hub blank flange, is uneven, the spinning step positioning is influenced, the coaxiality of the spinning formed hub rim is reduced, the yield of subsequent machining is reduced, and the yield of machining procedures is improved.
