Abstract
The invention discloses a kind of transmission shell vanishing mould black area process, its process is as follows：Ingate and cross gate, sprue are all connected together using saw blade, glue rifle, the catenulate casting system of shape；Filled out in advance with a small amount of molding sand and be trapped among casting system and transmission shell vanishing mould bottom periphery, casting system and transmission shell vanishing mould is firmly positioned；Artificial back-up sand is recycled, the molding sand containing binding agent is dosed and consolidates in the deep hole of transmission shell vanishing mould model, blind hole and dead angle area；With screwfeed formula puddle mixer into sandbox uniformly plus sand, using the ram-jolt of microseism platform and strike off molding sand；Molding sand repairing around sprue is smooth and make sand support with resin sand；Ready sprue cup is directed at ingate, one layer of asbestos cloth is put between sprue cup and ingate, reality is enclosed in back-up sand around sprue cup；In sandbox surrounding mounting vacuum tube road, using vavuum pump being vacuumized in sandbox.
Description
Technical field
The present invention relates to auto parts and components shell cast technical field, more particularly to a kind of transmission shell vanishing mould black area
Process.
Background technology
Evaporative pattern black area is the core link of lost foam casting, mainly uses the process of Bai Mo casting displacement casting, existing
Some evaporative pattern black area operating procedure generalizations, but for transmission shell vanishing mould there is deep hole, blind hole and dead angle area to cast
Not thoroughly, easily there is situations such as stomata cast is uneven, Quality Down of casting is caused, therefore, a kind of it is proposed that transmission case
Body evaporative pattern black area process.
The content of the invention
To solve the defect of prior art, the invention discloses a kind of transmission shell vanishing mould black area technique side
Method.
The invention discloses a kind of transmission shell vanishing mould black area process, its process is as follows：
（1）, transmission shell vanishing mould and sprue, cross gate put on rack, poured using saw blade, glue rifle in
Mouth and cross gate, sprue are all connected together, the catenulate casting system of shape；
（2）, transmission shell vanishing mould is arranged in special shape mo(u)lding box with the casting system structure that is connected, a small amount of molding sand is used in advance
Fill out and be trapped among casting system and transmission shell vanishing mould bottom periphery, make casting system and transmission shell vanishing mould firmly fixed
Position；
（3）, recycle artificial back-up sand, dose the molding sand containing binding agent and consolidate transmission shell vanishing mould model deep hole,
Blind hole and dead angle area；
（4）, hung on microseism platform with day handlebar transmission shell vanishing mould special shape mo(u)lding box, with screwfeed formula puddle mixer to sandbox
It is interior uniformly plus sand, molding sand using the ram-jolt of microseism platform and strikes off molding sand away from sandbox bottom 60-90mm；
（5）, the molding sand repairing around sprue is smooth and sand support is made with resin sand, then along the appearance of sand with blade surplus
Remaining sprue excision；
（6）, ready sprue cup be aligned ingate, one layer of asbestos cloth is put between sprue cup and ingate, in sprue cup
Reality is enclosed in surrounding back-up sand；
（7）, hung around vaccum-pumping equipment with day handlebar transmission shell vanishing mould special shape mo(u)lding box, vacuum is installed in sandbox surrounding
Pipeline, using vavuum pump being vacuumized in sandbox.
Beneficial effect is：By optimizing the black modulo operation technique of case of transmission, using artificial twice to evaporative pattern before back-up sand
Carry out advance back-up sand in sandbox, it is to avoid direct utilization puddle mixer back-up sand is uneven, to the blind hole on housing, deep hole and dead angle
Area's back-up sand consolidation, improves casting quality, so as to improve production efficiency.
Embodiment
The invention discloses a kind of transmission shell vanishing mould black area process, its process is as follows：
（1）, transmission shell vanishing mould and sprue, cross gate put on rack, poured using saw blade, glue rifle in
Mouth and cross gate, sprue are all connected together, the catenulate casting system of shape；
（2）, transmission shell vanishing mould is arranged in special shape mo(u)lding box with the casting system structure that is connected, a small amount of molding sand is used in advance
Fill out and be trapped among casting system and transmission shell vanishing mould bottom periphery, make casting system and transmission shell vanishing mould firmly fixed
Position；
（3）, recycle artificial back-up sand, dose the molding sand containing binding agent and consolidate transmission shell vanishing mould model deep hole,
Blind hole and dead angle area；
（4）, hung on microseism platform with day handlebar transmission shell vanishing mould special shape mo(u)lding box, with screwfeed formula puddle mixer to sandbox
It is interior uniformly plus sand, molding sand using the ram-jolt of microseism platform and strikes off molding sand away from sandbox bottom 60-90mm；
（5）, the molding sand repairing around sprue is smooth and sand support is made with resin sand, then along the appearance of sand with blade surplus
Remaining sprue excision；
（6）, ready sprue cup be aligned ingate, one layer of asbestos cloth is put between sprue cup and ingate, in sprue cup
Reality is enclosed in surrounding back-up sand；
（7）, hung around vaccum-pumping equipment with day handlebar transmission shell vanishing mould special shape mo(u)lding box, vacuum is installed in sandbox surrounding
Pipeline, using vavuum pump being vacuumized in sandbox.
Finally it should be noted that：Above example only not limits technology described in the invention to illustrate the present invention
Scheme；Therefore, although this specification with reference to each above-mentioned embodiment to present invention has been detailed description, this
Field it is to be appreciated by one skilled in the art that still can be modified to the present invention or equivalent substitution；And all do not depart from this
The technical scheme of the spirit and scope of invention and its improvement, it all should cover in scope of the presently claimed invention.
