Description
Technical field
The utility model relates to a kind of low pressure casting die, particularly a kind of aluminium alloy car knuckle casting mould.
Background technology
During the casting of aluminium alloy car knuckle, in order to avoid being mingled with because of molten aluminium alloy, dreg defect causes the various aspects of performance such as knuckle intensity, outward appearance not up to standard, need increase filter in its casting mould sprue bush, conventional filter is iron screen pack, as shown in Figure 1, 2.But after having cast, owing to there being the existence of iron screen pack on the dead head cut down, can not utilization be recovered, by waste disposal, great waste can only be caused.
Utility model content
The utility model aims to provide a kind of aluminium alloy car knuckle casting mould, and it improves for existing mold, and the dead head that the aluminium alloy car knuckle obtained to solving existing mold cuts down can not be recovered the problem of utilization.
The technical scheme of this aluminium alloy car knuckle casting mould is achieved in that
Described spindle casting mould, comprise upper die and lower die, upper model cavity and counterdie die cavity are combined to form the cast die cavity matched with spindle shape, size, and counterdie cast gate that bottom is opened coupling has sprue bush, and sprue bush has the cast passage communicated with cast die cavity;
Described cast channel middle is provided with chuck;
Described chuck is equipped with floamed ceramics filtrating piece, and it is through with some plug holes passed through for alloy molten solution, be provided with spreader above floamed ceramics filtrating piece, spreader is fixedly installed on patrix.
Further, described floamed ceramics filtrating piece structure in the form of annular discs.
Further, described plug hole is cellular distribution.
Further, cast passage is divided into two parts by described chuck, and the cast channel internal diameter above chuck is greater than floamed ceramics filtrating piece external diameter, and floamed ceramics filtrating piece external diameter is greater than the cast channel internal diameter below chuck.
Further, the cast channel internal diameter below described chuck from top to bottom reduces gradually.
Further, gap is left between described floamed ceramics filtrating piece and the spreader above it.
Preferably, described gap width is 0.4 ~ 1 millimeter.
Aluminium alloy car knuckle casting mould provided by the utility model, change the iron screen pack in existing casting mould into floamed ceramics filtrating piece, and carried out a series of improvement suitable with this floamed ceramics filtrating piece on this basis, adding the chuck for placing floamed ceramics filtrating piece, adding the spreader preventing floamed ceramics filtrating piece from producing offset deviation.Use the aluminium alloy car knuckle casting mould casting knuckle after improving, after cast, the dead head cut down does not exist increasing iron problem, can melting recycling, decrease wastage of material, reduce production cost; Simultaneously floamed ceramics filtrating piece is compared to iron screen pack, and filter effect is better, makes the aluminium alloy car knuckle performance of casting better.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is existing spindle casting mould structure schematic diagram;
Fig. 2 is iron filter screen structure schematic diagram;
Fig. 3 is spindle casting mould structure schematic diagram described in the utility model;
Fig. 4 is floamed ceramics filtrating piece structural representation.
Description of reference numerals:
In figure: 1. patrix, 2. counterdie, 3. cast die cavity, 4. sprue bush, 5. chuck, 6. cast passage, 7. floamed ceramics filtrating piece, 8. spreader, 9. plug hole, 10 iron screen packs.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Spindle casting mould described in the utility model, as shown in Figure 3,4, comprise patrix 1 and counterdie 2, patrix 1 die cavity and counterdie 2 die cavity are combined to form the cast die cavity 3 matched with spindle shape, size, counterdie 2 cast gate that bottom is opened coupling has sprue bush 4, and sprue bush 4 has the cast passage 6 communicated with cast die cavity 3;
Chuck 5 is provided with in the middle part of described cast passage 6;
Described chuck 5 is equipped with floamed ceramics filtrating piece 7, and it is through with some plug holes 9 passed through for alloy molten solution, be provided with spreader 8 above floamed ceramics filtrating piece 7, spreader 8 is fixedly installed on patrix 1.
As shown in Figure 1, 2, the filter adopted in existing spindle casting mould is iron screen pack 10, owing to itself having certain elasticity and degree of deformation, therefore it directly can be arranged in the cast passage 6 of sprue bush 4; The filter that this spindle casting mould adopts is floamed ceramics filtrating piece 7, and in order to solve its orientation problem, this casting mould is corresponding adds chuck 5 and spreader 8 structure.
Further, described floamed ceramics filtrating piece 7 structure in the form of annular discs, this structure is compared to iron screen pack 10, its plug hole 9 has certain length, when molten aluminium alloy liquid is by this duct, a part of impurity in liquation and clinker are stayed in duct, can play the effect of filtration further, ensure the purity of casting liquation.
Further, described plug hole 9, in cellular distribution, ensure that the liquid inventory by floamed ceramics filtrating piece 7, is unlikely to impact casting efficiency.
Further, simple and cost of manufacture is cheap from the viewpoint of manufacture craft, cast passage 6 is divided into two parts by described chuck 5, and cast passage 6 internal diameter above chuck 5 is greater than floamed ceramics filtrating piece 7 external diameter, and floamed ceramics filtrating piece 7 external diameter is greater than cast passage 6 internal diameter below chuck 5.
Further, cast passage 6 internal diameter below described chuck 5 from top to bottom reduces gradually, this just makes molten aluminium alloy enter from internal diameter smaller part, flow through internal diameter larger chuck 5 place floamed ceramics filtrating piece 7 again, the flow at two places is basically identical, keeps liquation flowing smooth and easy, avoid cast passage 6 internal diameter consistent time, because of the retardance of chuck 5 place floamed ceramics filtrating piece 7, flow diminishes and makes liquation produce accumulation herein herein.
Further, leave gap between described floamed ceramics filtrating piece 7 and the spreader above it 8, preferably, described gap width is 0.4 ~ 1 millimeter, can prevent floamed ceramics filtrating piece 7 from producing position skew because liquation impacts, be unlikely to again floamed ceramics filtrating piece 7 to crush.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
