Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
As shown in Figures 1 to 3: a kind of casting sandbox, including cope 1 and drag box, drag box are circular die 2, mould
The two sides of tool 2 are respectively equipped with hanging axis 26, and hanging axis 26 is located at the same of mold 2 diametrically, are convenient for mold 2 by setting hanging axis 26
Installation.Preferably, mold 2 is metal material, and stainless steel material such as can be selected, and those skilled in the art can also select as needed
Select other metal materials.By the way that the circular die 2 of the application is set as drag box, replace needing in a manner of whole dark chill regular
The bright chill of replacement is eliminated chill cost and is compared with traditional rectangular welding all purpose flask structure, consumption is greatly reduced, improves
Preceding placer iron ratio is 2.5:1, and placer iron ratio is 0.4:1 after improvement, saves quartz sand, resin, curing agent, and every case saves resin sand
755kg, according to 8 casees/day, 300 days/year are calculated, and save 181 tons of resin sands every year, are matched according to the sand rate of recovery 90%, resin
1.3%, curing agent 0.6% calculates, and saves 181.3 tons of quartz sand, and 410 yuan/ton of meters are worth 7.43 ten thousand yuan；Save resin 21.75
Ton, 15300 yuan/ton of meters, is worth 23.38 ten thousand yuan；10.88 tons of curing agent are saved, 2500 yuan/ton of meters are worth 3.81 ten thousand yuan, add up to
Save 44.53 ten thousand yuan/year.
2 bottom of mold is equipped with resin sand bottom 21, and the bottom of the mold 2 under resin sand bottom 21 is uniformly provided with several bed loads
Venthole 22 makes the resin sand of bottom have preferable venting quality, and circumferentially shape is evenly distributed on 2 bottom of mold to bed load venthole 22
Portion.Preferably, bed load venthole 22 sequentially forms three circumference from the inside to the outside, and in the specific implementation, those skilled in the art can
The quantity and distribution of bed load venthole 22 is set as needed.
It is equipped with the accommodating chamber for placing product model in mold 2, product wooden mold 23 can be such as placed, in the accommodating chamber
Between be equipped with resin sand inner hole filled layer 24, be surrounded by resin sand periphery filled layer 25 in the accommodating chamber, setting product wood
When model 23, while with resin sand potting resin sand inner hole filled layer 24 and resin sand periphery filled layer 25, product wooden model is taken out
Casting mold type chamber is formed after type 23.
The circular configuration that the selection of cope 1 and mold 2 cooperate, is also respectively equipped with hanging axis 26, hanging axis 26 in 1 two sides of cope
The same of cope 1 is located at diametrically, convenient for the installation of cope 1.Cope 1 is equipped with riser 11 and riser 11
The casting channel 12 of connection.
The sandbox of the application when in use, strikes off in one layer of 21 upper berth of the resin sand bottom resin sand of 2 intracavity bottom of mold,
It is filled with bed load venthole 22 automatically simultaneously, is placed centrally product wooden mold 23 after its hardening, fills tree simultaneously with resin sand
Rouge sand periphery filled layer 25 and resin sand inner hole filled layer 24, strike off after filling up, and pour in resin sand inner hole filled layer 24 is pressed into
Road model is concordant above with product wooden mold 23, takes out ingate model and product wooden mold 23 forms casting mold type chamber, with such
Pushing makees other with model blank cavity.After resin sand is fully cured, reconditioning mold cavity surface is cleared up and floats sand, brush fireproof coating,
