Abstract
The utility model discloses a reusable anti-deformation lacing wire of a vanishing mould, comprising anti-deformation lacing wires which are bonded with the vanishing mould made of polystyrene foam into a whole. The utility model is characterized in that the anti-deformation lacing wire has a metal body; a refractory coating layer with a certain thickness is painted on the bonding part of the anti-deformation lacing wires, and the anti-deformation lacing wires are bonded with the polystyrene foam vanishing mould through painting a resin glue layer on the surface of the refractory coating layer. The anti-deformation lacing wire adopts a metal plate body, so that a casting has no redundant parts, which does not need to be cleared and polished, thereby the manpower and energy sources can be greatly saved, and the operating environment can be greatly improved simultaneously. In addition, the metal plate body can be reused, so that the process cost can be greatly reduced, and more importantly, the rigidity of the polystyrene foam model can be greatly enhanced to effectively solve the deformation problem of the polystyrene foam model in painting the coating layer and molding jolt, so that the casting reject rate can be greatly reduced. As the utility model substitutes the prior wooden anti-deformation lacing wire again, the timber resources can be saved.
Description
Technical field
The utility model relates to a kind of disappearance mould that is used to cast, and is the lacing wire of a kind of novel disappearance mould anti-deformation specifically, can improve recycling rate of waterused, the distortion of the mould that prevents to disappear.
Background technology
At present, in casting industry,, mostly adopt the polystyrene foam model as the lost foam casting technology, because the soft rigidity of model matter of this material is lower, easy deformation in being coated with extension coating and moulding ram-jolt process.For addressing this problem, normally directly use wooden lath to be bonded in the appropriate location of polystyrene foam model, this lath is called as the anti-deformation lacing wire.Certain booster action has been played in this wooden lacing wire in actual applications really, but, in casting was used, also can there be following defective: the one, because molten metal has occupied the segment space that lath burns behind molten metal and the plank lacing wire catalytic combustion, on foundry goods, have more one and the equiform metal of plank, this piece metal needs will grind off with emery wheel, not only wasted metal material, make also that the plank lacing wire is disposable scraps, cause the consumption of timber resources, again waste of manpower; In addition, because the grinder buffing noise deteriorates significantly operating environment with the dust that flies upward; The problem of most critical is poor because of wood based panel wood strip body rigidity, and polystyrene foam model deformation problem takes place often, causes casting deformation, waste product unavoidably occurs, brings the raising of technology cost.
Summary of the invention
In view of above-mentioned situation, the utility model provides a kind of disappearance mould anti-deformation lacing wire that reuses, and it has and prevents to disappear moding shape, and is reusable again, takes into account the reduction environmental pollution, reduces the purpose of casting wasted product and technology cost.
For achieving the above object, the disappearance mould anti-deformation lacing wire that reuses that the utility model provides, comprise anti-deformation lacing wire with metal plate, for preventing the anti-deformation lacing wire of metal plate may to be bonded together after molten metal is with the foam gasification, and at metallic object plate and polystyrene foam model the sticking external coating of locating is had certain thickness fireproof coating layer, treat to use resin glue that metal plate is bonded on the polystyrene foam model after the fireproof coating layer drying.The anti-deformation lacing wire of the metal plate after bonding like this improves the rigidity of polystyrene foam model greatly, can prevent the distortion of foundry goods effectively.
In above-mentioned, can be according to the needs of polystyrene foam model, the anti-deformation lacing wire of metal plate can be the integral body that the lacing wire of two or many strip metals plate body is welded into arbitrary shape.
According to scheme of the present utility model, mentioned fireproof coating layer is a composite material body of selecting any and glue of silica flour, mullite powder, magnesia powder, alumine for use.
In a word, the disappearance mould anti-deformation lacing wire that reuses of the present utility model does not have fleshiness because of having adopted the anti-deformation lacing wire of metal plate, having made on the foundry goods, need not clear up polishing, has saved the manpower and the energy, and operating environment improves greatly simultaneously.In addition, metal plate is reusable, greatly reduces the technology cost, the more important thing is the rigidity of polystyrene foam model is improved greatly, solved the problem on deformation of polystyrene foam model in brushing paint layer and moulding ram-jolt effectively, the casting wasted product rate is significantly reduced.Because of having substituted the wooden anti-deformation lacing wire of existing use, saved timber resources again.
Description of drawings
Fig. 1 is a topology view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to accompanying drawing 1, shown a kind of disappearance mould anti-deformation lacing wire that reuses at first according to the shape of polystyrene lost foam mould 1, selects to make the anti-deformation lacing wire 4 of integrally-built metal plate; Bonding position brushing in the anti-deformation lacing wire 4 of described metal plate has certain thickness fireproof coating layer 3, in order to prevent bonding with molten metal.After treating fireproof coating layer 3 drying,, utilize resin glue 2 and polystyrene lost foam mould 1 bonding being integral, promptly finish the bonding of an anti-deformation lacing wire 4 the surface brushing resin glue 2 of the fireproof coating layer 3 in the anti-deformation lacing wire 4 of metal plate.Operation above repeating makes all firm being bonded on the polystyrene lost foam mould 1 of each anti-deformation lacing wire 4.
In the casting process, when utilizing the molten metal moulding polystyrene lost foam mould 1 gasification back is disappeared, and the anti-deformation lacing wire 4 of metal plate separates with foundry goods, after sloughing the fireproof coating layer 3 in the anti-deformation lacing wire 4, continues to reuse.
In the present embodiment, the brushing all around at the bonding position of the anti-deformation lacing wire 4 of described metal plate has certain thickness fireproof coating layer 3.But can be according to the size of foundry goods, model, can all can at the bonding position and the two sides brushing fireproof coating layer 3 of the anti-deformation lacing wire 4 of metal plate.
