Through old, or kind of electrolytes and dosage it is improper.（3）It is too violent to stir mud, or injection speed is too fast, makes to accompany gas in mud
Bubble, or slurry vacuum deaeration processing be not tight.（4）It is plaster mold overly moist, overdrying, excessively old, or model surface speckles with dust.
2nd, ftracture
Reason is：（1）Mud prescription is improper；（2）Old deficiency, inequality；（3）Misoperation, thickness base；（4）The demoulding
It is too early or too late；（5）The double part dry and wets for connecing base are inconsistent.
3rd, deform
Reason is：（1）Mud moisture is too high, and it is excessive to dry contraction.（2）Mud incomplete mixing, dry contraction and differ.
（3）Draining misoperation, base substrate gage distortion.（4）Model overly moist, or the demoulding are too early, and depanning misoperation, wet base is not put
Put down, put just.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of negative pressure grouting device, and the device reduces shaping slip casting
Caused bubble, deformation, cracking phenomena in journey.
In order to solve the above technical problems, the utility model adopts the following technical scheme that：
A kind of negative pressure grouting device, including vavuum pump, vacuum pipe, described vavuum pump connect with vacuum tank, vacuum tank

Some gypsum mold connections, gypsum mold are connected by grouting pipe with pulp injection tank, and vacuum pipe is provided with vacuum control valve.
After gypsum mold is neatly put on corresponding slip casting production line, matched moulds is carried out, top car is fixed, tracheae is plugged into
The relevant position of gypsum mold, vacuum control valve is opened, start vavuum pump and gypsum mold is vacuumized, take out in gypsum mold
Portion's air, it is set to be internally formed negative pressure state, external environment condition is normal barometric pressure, opens raw material grouting pipe valve, and mud exists
It will smoothly be poured under suction function in gypsum mold in gypsum mold, fill gypsum mold.
Using the utility model of above-mentioned technical proposal, compared with prior art, the characteristics of it is protruded, is：
Using vavuum pump and vacuum tank, make to form negative pressure in the gypsum mold on slip casting production line, slip casting process keeps negative
Pressure, due to suction function, the mud in gypsum mold does not have bubble, simultaneously because the effect of negative pressure, slurry prime is uniform, reduces
Deformation and cracking phenomena in injection molded process.
Further, the utility model optimal technical scheme is：
Described vacuum pipe connects with one end of compression pipe, the other end connection air compressor machine of compression pipe, compressed pipe
Road is provided with compression control valve.
After mould is expired by slurry tank, slurry is eaten 1.5 hours, be then shut off vacuum control valve, overfall, by unnecessary mud veclamation
To raw material.Compression control valve is opened, is pressurizeed using air compressor machine into gypsum mold, is pressurizeed 20 minutes, increase base substrate causes fine and close
Property and intensity, avoid blank deformation.After suppressing end, mould is molded, now wet base is molded.
In addition, mud enter gypsum mold after, gypsum mold absorbs large quantity of moisture, carry out slip casting next time it
Before, the moisture of gypsum mold absorption when need to dispose last slip casting, to keep the drying property of gypsum mold.Close vacuum control
Valve, valve compression control valve is opened, start air compressor machine, compressed air is pushed away by compression pipe, vacuum pipe and tracheae
It is pressed into gypsum mold, compressed air squeezes the moisture of gypsum mold absorbed inside, shortens the cycle that gypsum mold is dried,
Slip casting number is added, improves operating efficiency.
Timer and indicator lamp are provided with described vacuum control valve.
Timer is set, shows the negative pressure working time；Whether indicator lamp display alarm is in negative pressure working condition, avoids work
Make personnel's maloperation.
