Abstract
The utility model relates to a double-layer composite filtering net for molten materials, which is suitable for used for filtering molten metal in compression casting production and is formed by that the ring edges of the two net bodies of an upwards protruding arced net and a flat bottom net are jogged together. The utility model adopts a composite structure with an upper arced net and a lower bottom net, so that rigidity of the net bodies is enhanced to obtain strong deformation resistant ability, the nonuniformity of flow speeds when molten materials pass the nets can be decreased, and the filtering effect of molten materials and the internal quality of cast products can be improved obviously.
Description
The utility model relates to a kind of two-layer compound liquation screen pack, is specially adapted to filtering metal liquation in press casting procedure.
What generally use in die casting is produced at present, is a kind of single layer filter body with arc shape net.Its shortcoming is that the rigidity of net is poor, easy deformation, and misoperation then influences its filter effect slightly.And its individual layer arc web frame liquation by the time can make the liquation flow velocity inhomogeneous, influence casting quality.
The purpose of this utility model is the shortcoming that in use exists at existing screen pack, and a kind of rigidity height is provided, and non-deformability is strong, the two-layer compound liquation screen pack of good filtration effect.
The technical scheme that realizes above-mentioned purpose is: a kind of two-layer compound liquation screen pack, dictyosome ring limit is chimeric constitutes through two by convex net on one and a flat net.
The utility model improves the rigidity of dictyosome owing to adopted the composite construction of last convex arc net and flat net greatly, has stronger non-deformability, and filter effect is obviously improved.And the flow velocity inhomogeneities that produces in the time of can reducing liquation by net, the inherent quality of raising die-cast product.
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is that upward the convex arc net is the screen pack cutaway view of hemisphere face structure.
Accompanying drawing 2 is screen pack cutaway views that hemisphere face arc top has the last convex arc web frame of frustum of a cone side form down.
In Fig. 1, last convex net 1 is a semi-sphere, and the periphery of dictyosome is outwards translated into the circular arc bad selvedge, and the periphery of flat net 2 is also outwards translated into circular arc ring limit.The arc ring limit of its net 1 is embedded in the arc ring limit of net 2 both is connected.The square hole pattern that the last convex net 1 of this screen pack adopts by metal wire knitted, flat net 2 can adopt the square hole pattern of metal wire knitted, and also optional usefulness has the expanded metal lath of diamond hole.
That Fig. 2 provides is the another embodiment of this screen pack.Top of convex arc net is hemisphere face shape on it, and the bottom is frustum of a cone side, and other version is identical with a last embodiment.
Claims (3)
1, a kind of two-layer compound liquation screen pack is characterized in that: it by convex net (1) on one and a flat net (2) through the chimeric formation in two dictyosome ring limits.
2, two-layer compound liquation screen pack according to claim 1 is characterized in that: the periphery of going up convex net (1) and flat net (2) is outwards translated into circular arc ring limit, and the arc ring limit of its net (1) is embedded in the arc ring limit of net (2).
3, two-layer compound liquation screen pack according to claim 1 and 2 is characterized in that: going up convex net (1) is the weaving square hole pattern, and flat net (2) is the square hole net of diamond hole expanded metals or braiding.
