Description
Technical field
The present invention relates to investment casting casing methods, more particularly, to a kind of Hardening of Sodium Silicate Ceramic Shell spray washing
Device and sodium silicate shell shell side method belong to machinery manufacturing technology field.
Background technique
Model casting is also known as lost-wax casting, its product is accurate, complicated, close to the final form of part, can not process
Or seldom processing can be used directly, therefore model casting is a kind of advanced technologies of near-net-shape.
By the difference of binder used in shell processed, model casting can be divided into silester technique, silica solution technique and water glass again
Three kinds of glass technique.Wherein although waterglass full form casting process has that casting quality is relatively poor, but due to its technique
Condition requirement is relatively low, especially because having, raw material are cheap and easy to get, the lower advantage of casting cost, so waterglass fusible pattern
Casting is actually the full form casting process that China is most widely used at present, cast product is most.According to statistics, the current half in China with
On casting be to be produced with sodium silicate process.
Chemical hardening agent need to be used when sodium silicate process shell shell, curing agent used is that gelling can occur with waterglass instead
The compound answered.
Due to the presence of curing agent, and the viscosity of curing agent is big, and penetration is poor, is difficult to drip when drying only, when applying next layer,
Shell lamination defect can be generated when shell being caused to harden, influences shell linking intensity, occurred in the processes production such as later period casting
A large amount of defective products cause rate of wasted casting product, and repair rate is high, causes larger economic loss.
Therefore, it is badly in need of inventing a kind of curing agent that can rapidly and efficiently clear up remaining when sodium silicate process shell makes, with solution
Certainly existing technical problem.
Summary of the invention
The present invention provides the Hardening of Sodium Silicate Ceramic Shell shower water that a kind of structure is simple, easy to use and cleaning effect is good
Cleaning device and sodium silicate shell shell side method, to solve casting point caused by being easy when upper existing sodium silicate shell makes because of curing agent
The obvious technical problem of layer.
According to an aspect of the present invention, a kind of Hardening of Sodium Silicate Ceramic Shell spray washing device, including water storage box are provided
And spray equipment, the water storage box top is opening-like, and the two sides at the top of the water storage box are respectively equipped with transmission shaft, the transmission

Install live-roller, the spray equipment includes water pump and spray tube, and the water pump is installed in the water storage box, and with the spray
Shower pipe is connected with the live-roller, and the spray tube upwardly extends to form spray wall.
On the basis of above scheme preferably, the mounting plate bottom is equipped with rack gear, and the rack gear is adapted with the gear.
On the basis of above scheme preferably, the live-roller of opposite side is staggered.
On the basis of above scheme preferably, the live-roller is in hollow shape, and equipped with latticed on the live-roller
Nozzle.
On the basis of above scheme preferably, the two sides of the water tank are equipped with riser guide, and on the riser guide
Slidingtype is installed with guide pad.
On the basis of above scheme preferably, cushion is also installed on the guide pad.
On the basis of above scheme preferably, further include drying frame, it is described dry it is rack-mounted be located at the water tank side, it is described to dry in the air
It quarrels and is equipped with drying unit.
On the basis of above scheme preferably, water fender is additionally provided on the water tank.
The present invention also provides a kind of model casting sodium silicate shell shell side methods, including shell processed, dewaxing and Baking
Step, the shell step processed include chemical hardening process, and remaining curing agent removal process, institute are equipped in the chemical hardening process
Stating remaining curing agent removal process is, the shell in the chemical hardening process is passed through Hardening of Sodium Silicate Ceramic Shell as described above
With spray washing device, to remove the remaining curing agent.
A kind of Hardening of Sodium Silicate Ceramic Shell spray washing device of the invention is mutually tied by using water tank with spray equipment
It closes, may be implemented to carry out the cleaning of quick multi-angle to the shell in hardening process, thus to ensure that the remaining in shell is hard
Agent is effectively removed, and is had an impact during shell post-production to shell molding to avoid curing agent.
A kind of Hardening of Sodium Silicate Ceramic Shell spray washing device of the invention, by making full use of the structure of water tank, in water
Gear is set on case, by transmission wheeling driving gear rotation, so that gear drives the movement for being installed in mounting plate upper rack,
The movement for realizing mounting plate allows mounting plate to drive the movement of the live-roller of two sides in the lateral direction, realizes the opening to water tank
With closing.
In use, sodium silicate shell is first delivered to water tank upper by live-roller, pass through the spray tube and biography on water tank
Dynamic roller quickly rinses sodium silicate shell, and the remaining curing agent in shell is purged, when spraying after a certain period of time,
By the effect of wheel and rack, shell is allowed to fall into water tank, further completes to rinse it by impregnating, thus to ensure
Remaining curing agent in shell is completely removed.
Compared with prior art, the present invention has following advantages:
