Embodiment: as described in Figure 1, a kind of metal material forming die, described mould comprise die forming device and punch device, and described die forming device is connected with the punch device by jockey.
Described die forming device comprises moving die installing plate 9, all be hinged with movable Z-shaped locking lever 5 at the two ends of moving die installing plate 9, described punch device comprises punch installing plate 11, described jockey comprises the pull bar 7 that is arranged in pairs in punch installing plate 11 two ends, described pull bar 7 passes the via hole 24 on Z-shaped locking lever 5 one ends, is respectively arranged with die sinking piece 25 at the other end of pull bar 7.
Described die forming device comprises by moving die 14 and decides the mold cavity 13 that die 16 is formed, moving die 14 and decide to leave the precompressed amount between die 16 faying faces, move die 14 and decide die 16 and be separately positioned on moving die retainer plate 8 and decide in the die retainer plate 4, in moving die retainer plate 8 and decide to be provided with in the die retainer plate 4 matched moulds guide pillar 17, described moving die installing plate 9 is arranged on moving die 14 upper surfaces, moving die installing plate 9 is connected with moving die retainer plate 8 by bolt, the last turning of described two Z-shaped locking levers 5 is hinged on the two ends of moving die installing plate 9 respectively, the lower end of Z-shaped locking lever 5 be arranged on the locked mode plate 3 of deciding die 16 lower ends and fasten, the two ends of described locked mode plate 3 are inclined ramp, be provided with punch pilot hole 22 in moving die 14, described liquid metal inlet 23 is arranged on the moving die installing plate 9.
The punch installing plate 11 of described punch device is arranged on directly over the moving die installing plate 9, be provided with punch retainer 10 in the lower surface of punch installing plate 11, punch retainer 10 is provided with punch 12, and described punch 12 is corresponding with punch pilot hole 22 in being arranged on moving die 14.
Described mould also comprises liftout attachment, described liftout attachment comprises the die bottom plate 1 that is arranged under the locked mode plate 3, be arranged on the head part plate 20 at middle part, die bottom plate 1 upper surface, be arranged on the gripper shoe 2 of die bottom plate 1 upper surface one end and be arranged on the head part bar 15 of deciding to have in the die 16 spring 6, the lower surface of described head part plate 20 is provided with push rod 21, described push rod 21 passes die bottom plate 1, be provided with die pad lead 19 and release link 18 in the upper surface of head part plate 20, described die pad lead 19 1 ends are connected with locked mode plate 3, the other end is connected with die bottom plate 1, described release link 18 is passed locked mode plate 3 successively and is decided die retainer plate 4, described head part bar 15 upper ends are corresponding with mold cavity 13, described die bottom plate 1 by bolt successively with gripper shoe 2, locked mode plate 3 with decide die retainer plate 4 and be connected.
The present invention uses like this: earlier the mould that assembles is placed on the press bench, die bottom plate 1 is fixed on the press bench, punch installing plate 11 is fixed on the forcing press movable slider.During formation of parts, earlier the forcing press movable slider is moved upward, to extract out in the punch 12 driven dies 14, lever is motionless to be as the criterion climb to lock, at this moment, moving die 14 is connected as a single entity under the effect of locking lever 5 and locked mode plate 3 with deciding die 16, at this moment, melted metal liquid is injected in the mold cavity metal liquid filling die cavity with dosing container by the liquid metal hand-hole 23 on the moving die 14.The forcing press movable slider moves downward, punch 12 enters moving die 14 and replenishes and fill type and finish until pushing metal liquid, along with forcing press continues descending, 12 pairs of metals that solidified of punch are exerted pressure and are made it produce plastic deformation, not solidified metal liquid is applied isostatic pressure, make its crystallization and freezing under high pressure.Owing to move die 14 and decide to have reserved between the die 16 certain drafts, when punch retainer 10 touches moving die installing plate 9, punch 12 and moving die 14 apply external force to the part in the mold cavity 13 jointly, and part is solidified and plastic deformation under big pressure, finish up to being shaped.
After shaping is finished, forcing press moves upward, extract punch 12 earlier out, press ram continues to move upward, when the die sinking piece 25 that is arranged on pull bar 7 lower ends drives the swing arm of locking lever 5 after hinging pin shaft rotates, locking lever 5 is thrown off with locked mode plate 3, will move die 14 then and decide die 16 and separate.Ejecting mechanism on starting pressure machine promotion push rod 21, head part plate 20, release link 18 earlier moves upward along die pad lead 19, promotes head part bar 15 and moves upward, and ejects the part in the mold cavity 13, compresses spring 6 simultaneously.
After taking out the part in the mold cavity 13, the forcing press ejecting mechanism is return, and the forcing press movable slider moves downward, and moving die 14 and locking lever 5 also move downward.Under the effect of matched moulds guide pillar 17, guarantee moving die 14 and the matched moulds positional precision of deciding die 16.The latch hook of locking lever 5 is swing earlier outwards under the ramp effect of locked mode plate 3, stepped locked mode plate 3 after, inwardly swing under the gravity effect of its swing arm, the moving die 14 of locking and decide die 16 is finished a working cycles.
In addition, when moving die moves downward when touching release link 18, promote head part plate 20 and return, head part bar 15 resets under the effect of spring 6.
