The movement velocity difference of push plate relies on swing rod 31 to realize, the basic principle is that:(1) the ejection cylinder piston rod of die casting machine pushes pusher
Plate 27, at this time preceding ejector pin retaining plate 22, preceding push plate 23, rear push-rod fixed plate 24 and rear push plate 27 and all push rods being installed on it
It pushes ahead simultaneously, make pusher plate 15 (being pushed by pusher plate push rod 16) and remaining push rod while pushing casting disengaging type core, it is complete
It is demoulded at first time;(2) die casting machine ejection cylinder piston rod continuation pushes forward, and rear push plate 27, which has contacted, to be mounted on swing rod 31
Idler wheel 30 due to the effect of 135 ° of angles of swing rod make that inner edge push rod 5, muscle push rod (6,36), flange outer rim push rod are installed
20, muscle push rod (6,36), sprue push rod 37 the distance that board group part travels forward that is pushed forward surmount 16 (pusher plate of pusher plate push rod
15 are pushed by it) the distance S that travels forward0, thus casting generates relative displacement, casting with the type chamber being mounted in pusher plate 15
Smoothly demoulding.
As shown in figure 3, ejection first stage pusher plate push rod 16 and interior outer rim push-rod assembly ejection apart from identical,
Illustrate release of the pusher plate 15 with ejector half chamber in this course with the release of interior outer rim push-rod assembly be it is synchronous, the purpose is to
Casing casting first can smoothly be deviate from dynamic mould core;It has been touched in the second stage swing rod 31 of ejection, when swing rod 31 is around connecting rod
33 shafts 32 when going to shown position interior outer rim push-rod assembly will start Lead conditions;At 31 turns of phase III swing rod of ejection
It moves to the limit, the ejection distance So of the advanced pusher plate push rod 16 of interior outer rim push-rod assembly, specific calculating process are as follows at this time:
(1) S it is critical=L1Sin45°-L1Sin(45°-arcSin5/L2)=
=35 × 0.707-35 × Sin (45 ° of-Sin-15/42.5)=24.7-21.7=3
(2) the ejection distance S=5+L of pusher plate push rod 161Sin45 °=5+35 × 0.707=29.8
(3) the ejection distance Sz=(L of interior outer rim push rod1+L2) Sin45 °=
=(35+42.5) × 0.707=54.8
(4) the ejection distance So=Sz-S=54.8-29.8=25 of the advanced pusher plate push rod 16 of interior outer rim push-rod assembly
The operation principle of the present invention is that:
(1) die cast
As shown in Fig. 2, the sprue bush 1 of cold pressing press-in die of the injection punch head by the aluminium alloy of melting through die casting machine, through dynamic
The crossing current of mould mold insert 9 (shown in Fig. 4) to and ingate injection mold cavity and be pressurized and (solidify mold under high pressure);
(2) it is opened push piece
It is opened after cooling, die joint is opened, at this time since the package power of outer rim cartridge type core 2 (shown in Fig. 5) and inner mold core 3 is remote
Super fixed mold 8 (shown in Fig. 6), therefore be opened back cabinet casting and stay in dynamic model side;Start die casting machine liftout tank, rear push plate 27 is pushed away
It is dynamic, as shown in Fig. 2, (such as Fig. 9 when rear push plate 27 touches idler wheel 30 (shown in the Fig. 8) being mounted on swing rod 31 (shown in Fig. 7)
Shown, swing rod 31 is mounted on connecting rod 33,32 can be rotated around the shaft), swing rod 31 is turned to right pole from limit on the left position by side pressure
Extreme position realizes outer rim push-rod assembly in first, pusher plate 15 is synchronized by casing casting abjection dynamic mould core, with die casting
Machine ejection cylinder piston rod continues to promote, and interior outer rim push-rod assembly surmounts So to the realization of 15 movement position of pusher plate on releasing stroke
=25mm;
(3) it resets
With the progress of molding after pickup, release link 14 touches solid plate 11 first, with before the retrodicting of release link 14
Push plate 23, preceding push plate 23 successively push swing rod 31 and pusher board group part again until restoring to initial position shown in Fig. 2;
(4) next working cycles can be entered by repeating aforesaid operations.
Of the invention is mainly characterized in that:
(1) simple and reliable for structure
For seeming usual casing casting (shown in Fig. 1), but ejection difficulty after molding should not be underestimated, this is because should
The flange of casing and 104 barrel thickness of φ are too greatly different, according to traditional full push rod ejecting mechanism, then incite somebody to action in its joining place that crosses
Fragmentation caused by generation is concentrated by stress.It is released again when using two groups of push plate realizations, i.e., two groups of push plates of first stage, which synchronize, pushes away
Into pusher plate 15 and push rod resultant force are by casing casting disengaging dynamic mould core, but casing casting is remained in positioned at pusher plate 15 at this time
Type chamber in, in order to eject casing casting from type chamber, push rod must just have the advanced movement of an opposite pusher plate 15, pendulum
The swing rod swing mechanism that bar 31 and connecting rod 33 form can realize this target;
(2) connecting rod anti-loose structure
In swing rod swing mechanism shown in Fig. 2, connecting rod 33 is cantilever beam structure, and screw easily loosens after support force,
This can not only make projecting motion again fail, and more likely lead to a disaster, and a 12mm wide 10mm high is arranged in the intermediate of present connecting rod 33
Tenon, to be embedded in the corresponding groove of dynamic model cover board shown in Fig. 2 19, and be subject to left screw locking, can make to connect in this way
The rigidity and non-deformability of bar 33 are obviously improved;
(3) reduce friction, improve robust motion
As shown in fig. 7, swing rod 31 is not intended to the overall structure as in, two rollings are being mounted with rear 27 contact position of push plate
Wheel 30 (cooperates) with shaft clearance, can minimize in work in this way with the hard friction of rear push plate 27 and impact, make swing rod
31 around 33 shaft 32 of connecting rod rotation it is relatively steady.
(4) it uses and goes the convenient side gate charging of cast gate
For conventional design, the casing of the class formation generallys use the trumpet assembly fed from inner edge end cap, because in
Heart cast gate fills smooth homogeneous, be conducive to molten aluminum material by can be used as three dowels of secondary ingate from inner edge end cap to
Outer marginal zone flange cylinder type part is uniformly filled, but trumpet assembly is maximum the disadvantage is that causing inner edge end cap in the moment for breaking ingate
The deformation of end face and cast gate waste material must be cut off on lathe by special fixture.Using from outer marginal zone flange cylinder type part to inner edge
The side gate of end cap filling, its advantage is that going cast gate convenient, cover half can save one piece of de- cast gate waste material intermediate plate, but make to molding
At puzzlement be to only have the dowel of a φ 5 to may act as sprue when filling type to 56.5 inner edge end cap of φ, thus in outer rim cylinder
The end face of type core 2 increases three uniformly distributed 10mm wide dozzles (shown in Fig. 5), effectively compensates for required filling flow,
Receive preferable effect.
