All plates are made of plastic foamboard in the present embodiment, and the present embodiment is preferably by all connections
It is fixedly connected by the way of gluing.
Using the method for horizontal lost foam casting crossbeam described herein, specifically including the steps：
Step 1, the bottom of middle mould is bonded in the top of lower mould, the bottom of upper mould is bonded in the top of middle mould, made
Mould, middle mould and lower mould form a complete crossbeam evaporative pattern.
Step 2, by the evaporative pattern traverse of step 1, the front portion of crossbeam evaporative pattern is located at lower section, and with lower shoe 27 after
Face on the basis of surface, the rear filling foamed plastics plate at the rear of lower mould, the rear of middle mould and upper mould, makes whole evaporative pattern
Rear and the rear surface of lower shoe 27 are located in same level；Filling foamed plastics plate is in the low-lying place of crossbeam evaporative pattern, increasing
The overall intensity of strong the application middle cross beam evaporative pattern, prevent during step 3 sanding due to the weight and plastic foamboard of sand
Matter software feature and cause crossbeam disappearance calligraphy or painting model be collapsed.
Step 3, the evaporative pattern described in step 2 is turned and lain in the first sandbox, and the sanding into the first sandbox；
Whole spaces in crossbeam evaporative pattern are made to be each filled with sand.
Step 4, the second sandbox, and the sanding into the second sandbox are placed on the first sandbox, for covering whole crossbeams
Evaporative pattern, the first sandbox and the second sandbox are separated, crossbeam evaporative pattern can be exposed, facilitated crossbeam evaporative pattern in step 7 from sand
Dug out in case.
Step 5, the first sandbox and the second sandbox are turned, the second sandbox is located at the lower section of the first sandbox, and dig
Remove the plastic foamboard of filling.
Step 6, the 3rd sandbox is taken to be placed on the first sandbox, and the sanding into the 3rd sandbox；Using the 3rd sandbox sanding,
The another side of crossbeam evaporative pattern is covered by sand, open the first sandbox and the 3rd sandbox, can be by crossbeam evaporative pattern from the first sandbox
Inside expose and, be easy to step 7 to dig out crossbeam evaporative pattern, the horizontal evaporative pattern in the application is from the upper and lower part of the first sandbox
Dug out, the crossbeam evaporative pattern in sandbox can all be dug out, avoided the burning of casting process middle cross beam evaporative pattern completely and lead
The problem of environmental pollution of cause.
Step 7, unpack, the first sandbox, the second sandbox and the 3rd sandbox are separated, from the top and bottom of the first sandbox point
Mould, middle mould and lower mould are not dug out successively.
Step 8, in the sandbox after taking out evaporative pattern, the space paint coating where evaporative pattern；The swabbing in sandbox,
Scab is placed, after the completion of pouring, crossbeam will not be Nian Jie with sand, and obtained beam surface is more smooth.
Step 9, the spruing on the 3rd sandbox, for pouring cast iron.
Step 10, the second sandbox, the first sandbox and the 3rd sandbox are sequentially stacked from bottom to top, in the second sandbox, first
Form sand mold in sandbox and the 3rd sandbox, and from the sprue channel open of running channel it is upper downwards in cast melting cast iron and be cooled to cast iron and coagulate
Gu.
Step 11, shake out, the 3rd sandbox, the first sandbox and the second sandbox are separated, by the cast iron after solidification out of sandbox
Taking-up obtains crossbeam, more preferable for the surface of crossbeam, can be to the left polishing of crossbeam of taking-up.
The present embodiment in step 7, if having dug up the sand in sandbox, is being dug up the position stop-off of sand, taken a small amount of
Sand is filled in the part dug up, and holding sand mold is consistent with crossbeam, and the beam surface for preventing from obtaining has projection.
Plastic foamboard used in crossbeam evaporative pattern is made in the application after being dug out out of sandbox, can return
Receive to the factory of manufacture cystosepiment and be processed into cystosepiment use again, the recycling of cystosepiment is realized, compared to prior art
In burn crossbeam evaporative pattern, the application not only environmental protection but also good economy performance, when the application pours the cast iron of melting, the casting of melting
The one end of iron faster from sprue channel open away from sprue channel open is flowed, and the cast iron of liquid is from one end away from sprue channel open to sprue channel open
One end is gathered, and is evaporative pattern compared to one end away from sprue channel open in the prior art, the cast iron of melting will be with the combustion of evaporative pattern
Burn and slowly flow to one end away from cast iron, when the crossbeam to be poured is larger, possible crossbeam evaporative pattern has not yet burnt, and leans on
The cast iron that nearly sprue channel open goes out starts to solidify, and causes cast iron to pour failure, the application overcomes drawbacks described above, is greatly improved
The quality and efficiency of crossbeam casting, are poured once because each crossbeam evaporative pattern is simply possible to use in, so the application reduces horizontal stroke
The scrappage of beam evaporative pattern.
It is prior art not do the part illustrated in description above, or can be realized by prior art.
And it is only preferably case study on implementation of the present utility model that case is embodied described in the utility model, is not used for limiting
Practical range of the present utility model.The equivalent changes and modifications that i.e. all contents according to present utility model application the scope of the claims are made,
It all should be used as technology category of the present utility model.
