Product Description
who were the first people engaged in V process casting in China.
Automatic Vacuum Process Foundry Casting Molding Machine is used to produce various castings such as cylinder head, complicated pipe fittings, shell, housing, engine block, axle, brake drum, manhole cover, steel lining board etc. These casting parts are available in construction machinery, auto spare parts industry and so on.
Automatic Vacuum Process Foundry Casting Molding Machine is also called sand cast molding machine, vacuum seal casting molding equipments line, vacuum process molding and so on. It is a kind of dry sand casting molding machine which adopts no adhesive and based on the pressure produced by the vacuum pump, the pressure compacts dry sand to the needed shape. Filled dry sand(without adhesive, no mixing) in the flask, both sides of flask are covered with plastic film, and evacuated air inside, under a certain vacuum condition sand will lose relative motion, and then forming a mold.
1. Be with clear surface, clear outline, accurate size, good casting appearance.
2. Simplify equipment, save investment, reduce running and maintenance costs.
3. The labor force can be reduced by 35%, and the old sand reclaim rate is over 95%.
4. Decrease labor working intensity
5. Be with long service life
6. Be environmental during production
7. High productivity
VACUUM PROCESS MOLDING PROCESS:
Filled dry sand(without adhesive,no mixing)in the flask,both sides of flask are covered with plastic film,and evacuated air inside,under a certain vacuum condition sand will lose relative motion,and then forming a mold.Technical Process
1.Pattern and film heating
1)Fix pattern on the pattern carrier,and drilling holes on the pattern.
2)Heating the film.
3)Cover the heated film on the pattern.
2.Film forming and spraying coating.
Sparying coating on the formed film.
3.Place the flask
1)Keep the pattern carrier under negative pressure.
2)Putting the flask on the pattern which had covered by film and coating.
4.Vibrating and sand filling
1)Keep the pattern carrier under the negative pressure.
2)Filling the dry sand of appropriate mesh into the flask.
3)Vibrating to improve sand density.
5.Covering back film
1)Buldozing the surface of mold.
2)Covering the plastic film on the back of flask.
3)Connected the flask with the vacuum system.
6.Stripping
1)Relieving negative pressure of pattern carrier,pattern lose the attraction of EVA film
2)Stripping,and then molding completed.
7.Assembling flask and pouring
1)Molding the upper part and low part mold inthe same way.
2)Assembling flask with dowel pins,fastening the upper and lower parts.
3)Pouring under negative pressure.
8.Shakingout
1)After cooling for a specific time,relieved negative pressure of flask,sand wikll fall down with cast under normal pressure.
2)Sundries(like waste plastics,iron slag)are sieved from sand,sand will be reused after cooling.
