The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate the technical solution of the utility model.
Embodiment mono-:
Fig. 1 is the structural representation of the automobile aluminum wheel hub low pressure casting die that provides of the present embodiment.As shown in the figure, this automobile aluminum wheel hub low pressure casting die comprises patrix 1, counterdie 2, limit mould 3 and for mould is carried out to cooling cooling system.Cooling system comprises mould cooling apparatus, lower mould cooling apparatus and for cooling thermal center cooling device is carried out in casting thermal center position.Wherein, casting thermal center position comprises front hanging place, rear Gua Chu, front safety flange place, rear safety flange place etc.Can be near front hanging and/or hang afterwards and/or front safety flange and/or rear safety flange place arrange thermal center cooling device.
In the present embodiment, thermal center cooling device comprises after hanging cooling device 4, limit mould after patrix and hangs whole circle cooling device 5, limit mould front hanging to rib cooling device 6 and counterdie front hanging cooling device 7.Wherein, after patrix, hang that to hang whole circle cooling device 5 after cooling device 4 and Bian Mo cooling for the chamber wall of rear extension and rear safety flange position is carried out, limit mould front hanging to rib cooling device 6 and counterdie front hanging cooling device 7 for carrying out cooling to the chamber wall of front hanging and front safety flange position.As shown in Figure 2, after the mould of limit, hang whole circle cooling device 5 for be along the circumferential direction distributed in Qie Hougua cooling duct, rear extension cooling duct in limit mould 3 near after hang and put.As shown in Figure 3, limit mould front hanging to rib cooling device 6 for be along the circumferential direction distributed in front hanging in limit mould 3 to rib cooling duct and front hanging to rib cooling duct near front hanging setting.In the interior close patrix rib of patrix 1 corner, be also provided with rod iron air cooling equipment 8.
Upper mould cooling apparatus comprises that patrix slope cooling device 9, patrix PCD divide flow cooling device 11 with type cooling device 10 and patrix.Lower mould cooling apparatus comprises that counterdie centre circle cooling device 12 and counterdie emit mouth cooling device 13.
