Abstract
The invention discloses a die for casting a locking ring, which comprises an upper die (1), a lower die (2) and a sand core (3). The upper die (1), the lower die (2) and the sand core (3) are combined to form a casting cavity of the locking ring to be cast. The die is characterized in that the sand core (3) is fixed with the upper die (1), a whole including the sand core and the upper die is combined with the lower die during installation, and a junction surface between the upper die and the lower die can generally keep horizontal, so that even though sand grains or other sundries exist on the lower die, the sand core can keep horizontal and be free of slope, wall thickness of the locking ring is guaranteed, and acceptability of the casting is improved.
Description
Technical field
The present invention relates to a kind of casting mould, is a kind of mould that is used to cast binding ring concretely.
Background technology
Binding ring is the important component part of coal pulverizer, requires antiwear heat resisting at work, because binding ring is a revolving body, so the wall thickness of binding ring is all had higher requirement.Binding ring generally adopts the mode of casting to produce, and the mould that is used to cast binding ring mainly comprises mold, bed die and core, after mold, bed die and the core combination, forms the casting mold cavity of waiting to cast binding ring.At present, mold, bed die and core generally are direct combinations, during combination; Directly core is put on the bed die, again with mold and bed die combination, when core and bed die combination; Possibly have the grains of sand or other foreign material on the faying face of bed die and core; This has certain inclination when just causing core to be put on the bed die, the casting mold cavity shape that is surrounded by mold, bed die and core can change, and wall thickness everywhere can be variant; This will influence the quality of binding ring, may produce waste product when serious.
Summary of the invention
The technical problem that the present invention will solve is that a kind of mould that is used to cast binding ring that can guarantee the binding ring wall thickness preferably, improve the casting qualification rate is provided.
For solving the problems of the technologies described above, a kind of mould that is used to cast binding ring of the present invention comprises mold, bed die and core, after mold, bed die and the core combination, forms the casting mold cavity of waiting to cast binding ring, and said core and mold are fixed.
As preferably; Said core and mold are meant that fixedly core and mold are spirally connected, and said core is provided with at least one through hole that is used for ccontaining double-screw bolt; Mold is provided with and lead to the hole site and the corresponding installing hole of quantity, and nut one end face and mold upper surface offset.
After adopting said structure, the present invention has the following advantages: core and mold are fixed through the mode that is spirally connected, because core and mold are fixed; During installation, core and mold are done as a whole and the bed die combination, and the faying face of mold and bed die generally can both guarantee level; Even the grains of sand or other foreign material are arranged on the bed die like this; Core can guarantee that also level does not tilt, and this has just guaranteed the binding ring wall thickness, and the qualification rate of foundry goods has also had raising.
As improvement, described through hole is two, and through hole is symmetrical set along the axis of core.Adopt two through holes and be symmetrical set, make core and mold fixing more firm.
As improvement, also comprise backing plate, backing plate is arranged between nut and the mold, and backing plate upper surface and nut one end face offset, and backing plate lower surface and mold upper surface offset.Between nut and mold, backing plate is set, has avoided nut to act directly on the mold, better protect mold.
Description of drawings
Fig. 1 is used to cast the structural representation of the mould of binding ring for the present invention.
Fig. 2 is the structural representation of core of the present invention.
Shown in the figure, 1-mold, 2-bed die, 3-core, 3.1-through hole, 4-double-screw bolt, 5-nut, 6-backing plate.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed description.
As illustrated in fig. 1 and 2, a kind of mould that is used to cast binding ring, a kind of mould that is used to cast binding ring; Comprise mold 1, bed die 2 and core 3; After mold 1, bed die 2 and core 3 combinations, form the casting mold cavity of waiting to cast binding ring, core 3 is contained in the chamber that mold 1 and bed die 2 surround; Mold 1 is provided with the sprue gate, and said core 3 is fixing with mold 1.
Said core 3 fixedly is meant with mold 1; Core 3 is spirally connected with mold 1; Also comprise double-screw bolt and nut; Said core 3 is provided with at least one through hole that is used for ccontaining double-screw bolt 4 3.1, and mold 1 is provided with and through hole 3.1 positions and the corresponding installing hole of quantity, and nut 5 one end faces and mold 1 upper surface offset.
Described through hole 3.1 is two, and through hole 3.1 is symmetrical set along the axis of core 3.
Also comprise backing plate 6, backing plate 6 is arranged between nut 5 and the mold 1, and backing plate 6 upper surfaces and nut 5 one end faces offset, and backing plate 6 lower surfaces and mold 1 upper surface offset.
The mould that the present invention is used to cast binding ring is when assembling; Lower surface with mold 1 is placed on the horizontal plane up earlier; Then with core 3 vertical drops on mold 1, the through hole of core 3 3.1 is relative with installing hole on the mold 1, then with two diameters double-screw bolt 4 that is 20mm respectively part be contained in the through hole 3.1; Through double-screw bolt 4 with the core anchorage and seal sand; Adopt resin sand that through hole 3.1 is filled up and secures again, the part that then double-screw bolt is exceeded mold 1 is passed backing plate 6 and fixing with mold 1 through nut 5, so just core 3 has been fixed on mold 1; At last core 3 and mold 1 are together overturn, vertical drop is on bed die 2 then.
Be preferred embodiment of the present invention more than, the invention is not restricted to above embodiment, for example: described through hole 3.1 also can be one, three, four etc., and all structural variations of under design of the present invention, being done are all in protection scope of the present invention.
