Abstract
The utility model relates to a casting shuttering ladle comprising an inner shuttering layer, an outer shuttering layer wrapped at the outside of the inner shuttering layer and a reinforcement layer embedded between the inner shuttering layer and the outer shuttering layer, wherein the reinforcement layer is wrapped in the inner shuttering layer and the outer shuttering layer, two or more than two reinforcement layers can be embedded in the shuttering, the shuttering formed by the inner shuttering layer, the outer shuttering layer and the reinforcement layer is kettle-shaped, the casting shuttering ladle provided by the utility model can be made by the existing investment casting materials in factories, the making method is similar to investment casting process, the casting shuttering ladle is simple and convenient to make, high in surface finishment, high in refractoriness, convenient to use and capable of being repeatedly used, the slag inclusion phenomenon of castings is decreased, and meanwhile, a plurality of shutterings can be cast.
Description
Technical field
The utility model relates to a kind of cast formwork bag.
Background technology
In model casting is produced, often need to use casting ladle to pour into a mould some volumes and the larger foundry goods of weight ratio, conventional water incrustation and weld with iron sheet, inner lining refractory, this kind of casting ladle is heavier, because material particle size causes more greatly casting ladle rough inner surface, fineness is poor, easily cause foundry goods slag inclusion, during use, need toast longer compared with the time, inefficiency.
Summary of the invention
It is high that technical problem to be solved in the utility model is to provide a kind of refractoriness, and smooth surface is easy to use, reusable Ludox investment casting shell casting ladle.
The utility model adopts following technical scheme:
The utility model comprise internal mold shell, bag put the external mold shell outside internal mold shell and be embedded in internal mold shell and external mold shell between back-up coat, described back-up coat is put in internal mold shell and external mold shell by bag.
Described back-up coat is the wire loop of spiral.
Described back-up coat can be embedded in formwork with two-layer or two-layer above form.
The formwork bag that described internal mold shell, external mold shell and back-up coat form is kettle type.
The utility model good effect is as follows:
The utility model is directly used factory's current material, and full form casting process is made simple and conveniently, and surface smoothness is high, and refractoriness is high, easy to use, reusable, can also pour into a mould a plurality of formworks simultaneously.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model internal structure schematic diagram;
Accompanying drawing 2 is the utility model structural representation;
In the accompanying drawings: 1 internal mold shell, 2 external mold shells, 3 back-up coats.
The specific embodiment
As shown in accompanying drawing 1,2, the utility model comprise internal mold shell 1, bag put the external mold shell 2 outside internal mold shell 1 and be embedded in internal mold shell 1 and external mold shell 2 between back-up coat 3.During making, first use mould compacting casting ladle wax-pattern shape, then refractory material is set and be coated with to group, alternately stucco, dry.Surface is coated with zircon sand zirconium powder, transition zone and backing layer are with not carrying out flour sand, until be coated with, be suspended to certain thickness, guarantee that every layer of made shell is thoroughly dry, prevent micro-crack, to guarantee casing rigidity, fundamental sum model casting is consistent, but in manufacturing process, make back-up coat, concrete preparation method is as follows:
The first step: use casting ladle mould compacting casting ladle wax-pattern, then wax-pattern is repaired, make wax-pattern surface without defects such as salient point, pits, guarantee the fineness on wax-pattern surface.After guaranteeing that like this formwork completes, formwork inside smooth.
Second step: adopt Ludox technique to make shell the wax-pattern making, concrete operations are as follows: 1 ~ 3 layer adopts Ludox, zircon flour coating, spreads 120 order zircon sands; 4 layers adopt Ludox, do not carry out powder coating, spread 30 ~ 60 orders and do not carry out sand; 5 ~ 15 layers adopt Ludox, do not carry out powder coating, spread 16 ~ 30 orders and do not carry out sand; 16 layers adopt Ludox, do not carry out powder coating, are only coated with not stucco of coating; For guaranteeing that shell has sufficient intensity, in 16 layers, on the 8th layer of dried shell cylindrical, twine iron wire 4 ~ 5 circles, shell is when splendid attire molten steel like this, obstruct due to internal mold shell 1, the iron wire of back-up coat 3 can not melt in deliquescing, the iron wire of a few windings will in formwork, form back-up coat 3, back-up coat 3 with inner be internal mold shell 1, beyond back-up coat 3, be external mold shell 2.Back-up coat 3 can be a few iron wire loops, can be also wire netting, can be also wire loop, must guarantee that back-up coat is embedded between internal mold shell and external mold shell, can not layering.
The 3rd step: dried shell is put into dewaxing kettle wax material is deviate from, form Novel pouring formwork bag.
The 4th step: before use, with the shell that will pour into a mould, pack formwork bag into roasting kiln roasting, remove the moisture in formwork bag, improve the elevated temperature strength of casting ladle, avoid casting ladle temperature low, cause molten steel to pour casting ladle into after cooling too much, affect casting quality.
Before cast, with shell one, coexist in roaster and toast, and pour molten steel in stove into formwork bag, can pour into a mould shell.
For increasing the intensity of die housing, back-up coat 3 can be embedded in formwork with two-layer or two-layer above form.
Because formwork will heat, and the inside takes up molten steel, so back-up coat 3 will be put in internal mold shell 1 and external mold shell 2 by bag, otherwise exposed back-up coat 3 can even fusing of distortion.
The utility model can be used in the making of kettle type casting ladle.
The utility model can directly be used the current material of factory's model casting, and preparation method and full form casting process are similar, makes simple and convenient, surface smoothness is high, reduces foundry goods slag inclusion phenomenon, and refractoriness is high, easy to use, reusable, can also pour into a mould a plurality of formworks simultaneously.
