Description
Technical field
The present invention relates to molding sand sandbox and reduce molding sand casting method field, more particularly to a kind of molding sand sandbox and reduction
Molding sand casting method.
Background technology
Resin sand is short casting cycle, slightly higher compared with dry sand cost, but dry sand mold needs to dry kiln drying, and week is cast as to shorten
Phase, what raising efficiency first had to consider is exactly resin sand substitution dry sand, and why no substitution must be that certain sport technique segments are not dashed forward
It is broken, in addition, existing molding sand sandbox is made of two sandboxes, cope band riser, and pour into a mould cavity portion entirely in nowel, under
Case band chill, thus pours the casting for casting out round pie, and casting efficiency is low, and past resin sand replaces dry sand chill, casting to exist
The defects of hole is boiled in water for a while, then dress with soy, vinegar, etc. in bottom generation can not solve.
Therefore, it invents a kind of molding sand sandbox and to reduce molding sand casting method necessary to solve the above problems.

The purpose of the present invention is to provide a kind of molding sand sandbox and molding sand casting method is reduced, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the present invention provides the following technical solutions：A kind of molding sand sandbox and molding sand casting method is reduced,
Including cope and drag box, the drag box is set to cope bottom, and the drag box both sides external is equipped with connecting rod, institute
It includes cope ectosome to state cope, and the cope ectosome is internally provided with cavity, riser is equipped at the top of the cavity, under described
Sandbox includes drag box ectosome, and graphite substrate is equipped on the inside of the drag box ectosome, resin sand is equipped on the inside of the graphite substrate
Layer, resin layer of sand bottom are equipped with filled layer.
Preferably, the graphite substrate thickness is set as 30-50mm.
Preferably, drying temperature is set as 350 DEG C in the step 5, and drying time is set as 40-50 hours.
The invention also discloses a kind of reduction molding sand casting method of molding sand sandbox, casting method includes the following steps：
Step 1：Cope is made, the cope of metal material is made by the method for moulding by casting；
Step 2：Drag box shell is made, drag box shell is made by the method for moulding by casting；
Step 3：Graphite substrate is covered entire drag box outer casing inner wall by filled graphite substrate, and diameter area is more than
Casting base diameter area, graphite upper surface keep horizontal with drag box shell；
Step 4：Potting resin layer of sand, resin sand is filled to graphite substrate, and upper surface keeps water with graphite substrate
It is flat；
Step 5：After drag box is carried out, for the first time in use, disposably being dried in drying box；
Step 6：It to preheat and can use when using for the first time, splashing scald accident otherwise easily occurs, preheating method is to use
Casting liquid having one's hair waved or other mode of heatings；
Step 7：The sandbox of one specification will often adapt to various sizes of casting, at this moment for large-size
Sandbox, other than the part contacted with casting is using resin layer of sand, resin layer of sand bottom can be carried out with cement or gypsum material
Filling.
The technique effect and advantage of the present invention：Routine two has been well solved by fully filling molding body with cheap material
It is insufficient existing for kind sand mold, casting efficiency is substantially increased, working environment is improved, reduces casting cost；Existed by casting
Molding, conveniently stripped in cavity inside cope, and production efficiency is high；Using resin layer of sand, it is short to shorten casting cycle, carries
High efficiency, and casting not will produce in bottom and boil in water for a while, then dress with soy, vinegar, etc. hole.
