Description
Technical field
The utility model belongs to the precision-investment casting field, is meant that especially the drying device in a kind of formwork manufacturing process improves.
Background technology
Precision-investment casting is a kind of casting technique of cutting less or not having cutting; Its application is very extensive; Be not only applicable to the casting of all kinds, various alloys; And the casting dimension accuracy of producing, surface quality are higher than other casting method, even other casting method complicacy of being difficult to cast, high temperature resistant, the foundry goods that is difficult for processing, all can adopt melted module precise casting technology to realize.The existing high fields of ask for something precision such as aircraft engine, steam turbine that have been widely used in.
Existing investment precision casting technology is realized through following operation:
1, makes metal pattern, make the pattern of workpiece according to the product design pattern;
2, make wax-pattern, wax is injected in the pattern, treat wax cooling back taking-up wax-pattern, at this moment wax-pattern consistent with the natural scale of workpiece (actual size can change according to the shrinkage rates of casting to some extent);
3, hang sand, use casting model powder, the wax-pattern surface is stained with, is stained with Star to certain thickness, bonding each other for casting model powder understood and in casting model powder, added adhesive glue;
4, dewax, the wax-pattern behind the extension sand is put into water and is boiled, and stays arenaceous shell after the wax fusing;
5, roasting is carried out roasting with arenaceous shell, makes it have certain intensity;
6, casting, in the arenaceous shell of molten iron pouring after the roasting, the molten iron cooling back demoulding promptly obtains foundry goods;
In hanging the sand process, need just can reach needed thickness through extension sand repeatedly, in common making; All hang sand through 5 times and accomplish this operation, the step that is adopted is that mold base is immersed in the adhesive glue; Be stained with the mold base sandblast of adhesive glue to the surface; Mold base after the sandblast is immersed (curing agent generally is to adopt ammonium chloride solution in model casting) in the curing agent pond, drying, and then repeat to immerse the adhesive glue step.And in dry run, dual mode is arranged, a kind of is air dry, but receives climatic influences bigger, can't carry out steady production, existing no longer employing.The 2nd, heat drying, this just needs a large amount of energy, has increased production cost.
The utility model content
In order to improve efficiency of energy utilization, reduce production costs, and guarantee the stability of production, ad hoc meter the utility model.
The utility model is realized through following technical scheme:
A kind of drying device; Comprise a shell, there have a division board with holes that drying device is divided in the middle of the described enclosure to be two-layer up and down, in each layer, a roller-way arranged; Said two roller-ways provide power by motor and supporting reducing gear respectively and move; The movement rate of said roller-way is 5-20cm/mim, and the direction of motion of described two roller-ways is opposite, can be placed with pallet on said each roller-way; Pallet on the roller-way of described upper strata is used to place formwork to be dried, and the pallet on the described lower floor roller-way is used to place the arenaceous shell after the casting; Said shell has with every layer of roller-way corresponding charging aperture and discharging opening; The same corresponding roller-way of the bottom of said charging aperture and discharging opening is roughly on same plane; The charging aperture of described two-layer roller-way is not at the homonymy of shell; On described drying device upper strata low speed blower fan and temperature control equipment are installed, described temperature control equipment control temperature is between 25 ℃-45 ℃.
As further improvement, the shell of the described corresponding upper strata roller-way outside, the charging aperture place has a formwork pallet to be dried to push machine, and the discharging opening place has a formwork pallet to be dried to pull out machine; The shell outside of described corresponding lower floor roller-way, charging aperture place have a casting back arenaceous shell pallet to push machine, and the discharging opening place has a casting back arenaceous shell pallet to pull out machine.
As further improvement, there is heat-insulation layer in the drying device outside in the said formwork manufacturing process, to reduce thermal loss, improves efficiency of utilization.
As further improvement, described low speed fan outlet is installed on the feed end on drying device upper strata.
The beneficial effect of the utility model is that the heat that is discharged through the back arenaceous shell of casting adds formwork to be dried through radiation mode, does not so just need to provide separately heat, has realized energy-saving effect, simultaneously, has also promoted the cooling of casting back arenaceous shell.

The specific embodiment
Below in conjunction with accompanying drawing, come the present invention is described further, but present embodiment is not for limiting the scope of this patent.
See figures.1.and.2, a kind of drying device comprises a shell 1; The top of shell is provided with steam vent, and there have a division board with holes that drying device is divided in the middle of the described enclosure to be two-layer up and down, in each layer, a roller-way arranged; Said two roller-ways provide power by motor and supporting reducing gear respectively and move; The movement rate of said roller-way is 5-20cm/mim, and the direction of motion of described two roller-ways is opposite, can be placed with pallet 8 on said each roller-way; Pallet on the described upper strata roller-way 6 is used to place formwork 7 to be dried, and the pallet on the described lower floor roller-way 9 is used to place the arenaceous shell 10 after the casting; Said shell has with every layer of roller-way corresponding charging aperture and discharging opening; The same corresponding roller-way of the bottom of said charging aperture and discharging opening is roughly on same plane; The charging aperture of described two-layer roller-way is not at the homonymy of shell; On described drying device upper strata low speed blower fan 11 and temperature control equipment are installed, described temperature control equipment control temperature is between 25 ℃-45 ℃.
