Description
Technical field
The utility model large size disappearance die casting reinforcing rib, and in particular to a kind of large size lost foam casting part mould support is fixed
The device of type.
Background technique
Lost foam casting (also known as cavityless casting) is made of foamed plastics (EPS, STMMA or EPMMA) high molecular material
It is buried after by dip-coating fireproof coating and drying as the design of part with casting to be produced, the duplicate full mold mold of size
Through three-dimensional vibrating moulding in drystone sand, molding flask of casting pours into molten metal liquid under negative pressure state, makes macromolecule
Material model replaces the disposal molding New Casting Technique formed after cooled and solidified raw by thermal evaporation extraction, and then by liquid metals
Produce the novel casting method of casting.
Compared with conventional casting technologies, Technology of EPC has impayable advantage: 1, casting quality is good, cost
It is low；2, material is unlimited, and size is all suitable；3, precision height, any surface finish, reduction cleaning, saving machine add；4, internal flaw subtracts significantly
Few, cast structure is fine and close；5, extensive, mass production can be achieved；6, it is cast suitable for the mass production of identical casting；7,
It is controlled suitable for manual operation and automatic assembly line production run；8, the production status of production line meets environmental protection technology parameter and refers to
Mark requires；8, the working environment and working condition, reduction labor intensity, the reduction energy that can substantially improve foundry production line disappear
Consumption.
Lost foam casting usually requires following steps: the selection of foamed bead；Modelling；Model group composite variety；Model
Coating；Vibration molding；Casting displacement；Cooling cleaning；Wherein mould coatings refer to that the face the foamed model of cavityless casting (Bai Mo) is required
One layer of certain thickness coating is applied, casting mold inner casing is formed；The effect of its coating is the strength and stiffness in order to improve EPS model,
Improve the anti-molding sand scouring capability of model surface, prevent plus sand during model surface is damaged and vibration molding and mould when negative pressure shaping
The deformation of type, it is ensured that the dimensional accuracy of casting；Paint specially for disappearing cast mold adds water and stirs in mould wash mixer, obtains it
To suitable viscosity.Coating after stirring is put into container, is coated model group with the method for leaching, brush, leaching and spray.It is general to apply two
To three times, each coating layer thickness is 0.3~0.5mm, selected according to casting alloys type, planform and size difference.It applies
Layer is dried at 40~50 DEG C.
Currently, lost foam casting is chiefly used in more complicated casting, but for casting biggish for some figures, disappear
Lost pattern casting easilys lead to deform, and either dip-coating, spraying, showering is still brushed, and the upper mold for crossing coating and mold rack exist
During drying due under hygrometric state intensity it is lower, the weight of coating and the position put in addition, during drying all
It can deform, so that model has had deformation before group case moulding, it cannot be guaranteed that its flatness；Existing for big part evaporative pattern
Greatest problem is problem on deformation, not can solve always now.
Utility model content
The utility model overcomes the deficiencies in the prior art, the technical problem to be solved is that: one kind is provided and is avoided
The evaporative pattern mold support device of large-scale evaporative pattern casting deformation.
In order to solve the above technical problems, the technical scheme adopted by the utility model is: large-scale disappearance die casting reinforcing rib,
It include: evaporative pattern mold and mold supporting frame, the mold supporting frame uses metal supporting frames, and mold supporting frame is welded and fixed,
The evaporative pattern mold is fixed on mold supporting frame, and the contact surface of the evaporative pattern mold and mold supporting frame is coated with evaporative pattern
Coating forms lost foam paint layer, and the lost foam paint layer is with a thickness of 0.9~1.5mm.
The mold supporting frame is by transverse supporting rod, vertical supporting rod and is connected and fixed bar and forms, the transverse supporting rod and perpendicular branch
The fixation of strut vertical welding forms supporting surface, is welded and fixed by being connected and fixed bar as stable frame between the supporting surface
Structure, evaporative pattern mold are fixed on inside mold supporting frame.
The mold supporting frame uses square steel tube or zinc-plated square iron pipe.
The utility model has the beneficial effect that compared with the prior art
One, the utility model supports large-scale evaporative pattern mold by the way that metal supporting frames are fixed, can guarantee that entire mold exists
Move, coating, casting, in cooling procedure, will not deformation occurs, guarantee the flatness of mold and casting workpiece, product of deducting a percentage
Quality lowers defect rate；
Two, the utility model is coated with lost foam paint in the contact surface of evaporative pattern mold and mold supporting frame and forms evaporative pattern
Dope layer can guarantee to contact during metal is supported on casting, cooling with casting, so as to avoid the shape of mold supporting frame
Become, ensure that the intact of casting, while mold supporting frame can be enable to reuse, reduces production cost；
Three, the utility model whole device is simple for structure, common using material, manufacturing process is simple, working service cost
It is lower, and can be used continuously, it is low in cost, it is practical.
Detailed description of the invention
The utility model is described in more detail with reference to the accompanying drawing:
Fig. 1 is the structural schematic diagram of the utility model；
