Abstract
The utility model provides a graphite mould for up-guiding continuous casting of special copper pipe, belonging to a metal casting equipment. The main technical characteristic is that the butt joint of a graphite mould and a chiller adopts a clamping desk type, the assembly of a mould core and a mould body is fitted by pins and fastened by screws. The graphite mould provided by the utility model is used without looseness or distortion for a long time, insuring the stability of castings cross-section dimension.
Description
The invention belongs to metal casting machine.
On draw in the continuous casting of metal pipe craft, graphite mo(u)ld is the vitals of crystallizer, its top is docked with cooler and is formed crystallizer.Graphite mo(u)ld generally is made of die body and core rod, and the space between die body and the core rod is the crystallisation by cooling chamber of copper liquid, and the cross section of this chamber is identical with the cross section that casts out pipe fitting.Existing die shape is the garden column, its top is cone structure, this cone surface matches with the inverted cone surface of crystallizer interface, buoyancy by copper liquid, mould is supported, is docked on the crystallizer, and the interface of the core rod of mould and die body generally also is a cone structure, by copper liquid buoyancy core rod is supported equally, is fixed on the die body.Docking of above-mentioned mould and cooler and docking of core rod and die body, all by means of the buoyancy of copper liquid, the distortion of the loosening and mold cools down crystallisation chamber of mould very easily takes place in long-time production, has a strong impact on the stable of foundry goods cross sectional dimensions, even production operation can not be gone on.
The objective of the invention is, provide a kind of mould and cooler dock and mould core docks very stable, firm graphite mo(u)ld with die body, use looseningly, indeformable for a long time, guaranteed the stability of foundry goods cross sectional dimensions.
The special-shaped copper pipe graphite mo(u)ld of continuous up-casting of the present invention, form by die body and core rod, core rod is made of die mandrel and base, its main feature is, put two or several horizontal ledge on the cone structure of die body outer surface, the described boss geometrical plane that exists together, this boss can extend into along the groove on the cooler interface in the interface, when with interface in corresponding concave station when being in same plane, the rotation boss, it is snapped in the concave station, so die body is a card platform structure with becoming copper liquid buoyant support being connected of cooler, very firm, stable, another main feature is, described die mandrel and base are single piece, base top is die mandrel, put two or several alignment pins and one or several hole, garden on the base, put and the corresponding cotter way of described alignment pin at the lower surface of die body body wall, and with the corresponding screw in hole, described garden, alignment pin on the base is inserted the cotter way of described die body body wall lower surface, make die body and core rod location, the hole of passing on the described base with bolt, garden screws in the screw of die body body wall lower surface, so that die body and core rod are connected as a single entity.
For the mould of large-size, the horizontal ledge on the described die body outer surface also can be established 3 or 4.
Alignment pin on the described core rod base can be 3 to 6, and hole, described garden and screw can be 2 to 6.
The copper liquid import of mould generally is located at the die body side wall lower ends, but preferably this import is located on the core rod base, is good with 1 to 10.
Entire die is made by graphite, and the outer surface of die body also can be the garden cylindricality, and corresponding cooler interface also should be the garden tubular.Graphite mo(u)ld of the present invention also can be used for the continuous up-casting aluminium and aluminium alloy pipes.
Graphite mo(u)ld of the present invention adopts card desk-top with docking of cooler, and the alignment pin location is adopted in the assembling of core rod and die body, and the screw-tightened formula is used looseningly, indeformable for a long time, guarantees stablizing of foundry goods cross sectional dimensions.
Accompanying drawing is embodiments of the invention, is continuous up-casting rectangle copper pipe graphite mo(u)ld, and details are as follows, and Fig. 1 looks cutaway view for master of the present invention, (1) core rod base among the figure, the import of (2) copper liquid, (3) die body, (4) the crystallisation by cooling chamber of copper liquid, (5) die mandrel, (6) horizontal ledge.Fig. 2 is the A-A face cutaway view of Fig. 1.Fig. 3 looks cutaway view for the end of the present invention, and (7) are set bolt, is used for core rod is fixed on die body.(8) be alignment pin, be used for the location between core rod and the die body.Fig. 4 is a side view cutaway drawing of the present invention.
