Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries. Over 60% of all metal castings are produced via sand casting process.

The invention provides a large casting lost-foam resin sand casting process which comprises steps of mould manufacturing, mould assembling, paint spraying and drying, resin sand vibration-filling, bottom-injection type semi-closed casting system applying, a casting clearing process and the like. A large casting lost-foam model is processed in a programmed and digital manner; the mould material replace rare korean pine wood with reproducible low-cost EPS foam, so that a great deal of non-renewable resources are saved; meanwhile, the processing performance and efficiency are greatly improved. A pouring system is designed with a gas exhaust channel, so that complex operations such as operation of eliminating a mould cavity lost mould by adopting methods such as combustion, and the like are avoided, limit in aspect of a metal material of a lost-foam casting process is further broken through, and therefore, the application field is wider.

Sand casting mold and method for preparing bucket tooth tip by using sand casting mold

InactiveCN109047645AImprove breathabilityHigh strengthFoundry mouldsFoundry coresSand castingCasting mold

The invention relates to a sand casting mold and a method for preparing a bucket tooth tip by using the sand casting mold, belonging to the technical field of machinery. The sand casting mold is prepared from the following raw materials in parts by weight: 100 parts of modified quartz sand, 12-30 parts of wollastonite, 4-6 parts of calcium bentonite, 1-4 parts of pulverized coal, and 6-9 parts ofwater. The sand casting mold has the advantages of good air permeability and good performance, and can provide molten metal with good flowability and reduce surface defects of castings, and the buckettooth tip by using the casting mold can effectively improve the mechanical properties thereof.
