The specific embodiment
By Fig. 2, known, a kind of gear housing die casting of the present utility model, comprise cover half frame 4, dynamic model frame 3, cover half 6, dynamic model 2, sprue bush 7, Angle Pin, fixed mold 1, fixed mold 2 11, fixed mold 3 12, dynamic model extra block 17, guide pillar 13, guide pin bushing 8 and the first slide block 20, the second slide block 24, described three fixed molds and cover half 6 are fixed together, described two slide blocks and dynamic model 2 link together, and realize action interlock by Angle Pin and cover half 6; Described the first slide block 20, the second slide block and cover half 6, dynamic model 2, fixed mold 1, fixed mold 2 11, fixed mold 3 12, dynamic model mold insert 19 form gear housing die cavity 1, the running gate system of mould is comprised of the cross gate 15, the ingate 14 that are opened on cover half, wherein cross gate 15 is made as five in mould gate punishment, mould overflowing system is comprised of cover half slag trap 21, dynamic model slag trap 16, the first slide block slag trap 22, the second slide block slag trap, dynamic model extra block slag trap 23, and wherein dynamic model slag trap 16 outsides offer exhaust passage 18.
By Fig. 3, being known, is fixed mould structure schematic diagram.Cover half is provided with cover half frame 4, fixed mold 1, fixed mold 2 11, fixed mold 3 12, ingate 14; Cross gate 15 and cover half slag trap 21, ingate 14 and cross gate 15 form running gate system, and cross gate 15 is made as five in ingate 14 cast gate punishment.On cover half frame 4 and cover half 6, offer cooling water channel 5, to guarantee mold hot balance.
By Fig. 4, being known, is the structural representation of dynamic model.Described dynamic model 2 is provided with dynamic model slag trap 16, on the first slide block 20, the second slide block 24, be respectively equipped with the first slide block slag trap 22, the second slide block slag trap and dynamic model extra block slag trap 23, on dynamic model 2, offer moving die exhaust passage 18, gear housing mold cavity is by gap and 18 exhausts of moving die exhaust passage between two slide blocks and cover half 6, dynamic model 2, therefore in die cavity, original air just can be discharged easily after being pressed into motlten metal, the flow resistance that this has just reduced motlten metal, has increased the mobility of motlten metal.
The course of work of mould: during mould matched moulds, under the guiding and positioning action of guide pillar 13 and guide pin bushing 8, Clamping System drives dynamic model 2 to move to cover half 6 directions, the first slide block 20, the second slide block 24 are under Angle Pin effect simultaneously, arrive operating position, make mould closed, and provide enough clamp force locking dies by Clamping System.Then start die casting, by die casting machine manipulator, aluminium liquid is poured in pressure chamber and through injection mechanism and exerted pressure and by sprue bush 7, cross gate 15, ingate 14, entered respectively the die cavity 1 of mould, after pressurize a period of time, Clamping System drives dynamic model 2 to moving away from cover half 6 directions, the first slide block 20, the second slide block 24 separate under Angle Pin effect simultaneously, and then push rod is released gear housing foundry goods from mould.During matched moulds, push rod resets, and mould is prepared die casting next time.
The gear housing foundry goods that the utility model mould is produced is complicated especially, and die cavity is also very complicated, and the running gate system of mould and the design of overflow system are most important to casting quality quality.The running gate system of mould is located on dynamic model, and during die casting, aluminium liquid is pressed into and imports gear housing die cavity through cross gate and five ingates through cast gate.Cross gate and ingate are all through calculating emulation, through five ingates, flow into the molten metal of die cavity, substantially be simultaneously full of die cavity everywhere, therefore the quality consistency of every die casting be can guarantee, after molten metal enters die cavity by cross gate and ingate, eddy current bag gas and oxide inclusion defect can not produced simultaneously.Cover half is provided with cover half slag trap, dynamic model is provided with dynamic model slag trap, the first slide block, the second slide block is respectively equipped with the first slide block slag trap, the second slide block slag trap and dynamic model extra block slag trap, dynamic model offers exhaust passage, mold cavity is by the gap between slide block and fixed half and moving half and the exhaust of moving die exhaust passage, therefore in die cavity, original air just can be discharged easily after being pressed into motlten metal, this has just reduced the flow resistance of motlten metal, increased the mobility of motlten metal, thereby make motlten metal can arrive smoothly each position of die cavity, the product of die cast is not easy to occur defect thus, improved the quality of product.In addition dynamic model is provided with push-rod hole, so that die sinking rear push-rod is released gear housing foundry goods.On stationary mould for mould frame and cover half, offer cooling water channel, to guarantee mold hot balance.
This mould is used dynamic model mold insert, has many good qualities, and first can avoid mould complicated processing, reduces costs, time saving and energy saving, and second can be convenient to change after mold insert partly damages, and avoids mould to scrap, cost-saving.
