Sand casting is one of the casting, sand casting mold used generally made from a mix of sand mold and core.Because of sand mold casting molding materials used in the cheap, simple mould manufacturing, piece of casting production, the batch production and mass production are able to adapt to, for a long time, has been the basic technology of casting production.At present, internationally, in all casting production, 60 to 70% of the casting is made of sand mold production, and about 70% of them are using clay sand mold production.
Sand mold casting of crusher wear parts at home and very common, like jaw, high chromium plate hammer, crushing wall, rolling mortar wall and so on, because in crusher equipment, as a larger wear resistant castings, relatively accuracy is not high, especially such as jaw, out of the finished product is almost no lathe polishing, crushing wall, roller rolling mortar wall, is just like casting parts need lathe polishing, so especially suitable for use sand mold casting, because of the sand mold casting jaw plate, high chromium plate hammer, crushing wall rolling mortar wall, roller, leather and so on the crushing equipment of wear parts more durable than other products such as lost foam casting process more than 20%.But lost foam casting has high dimensional precision, small machining allowance, dry sand shakeout To clean up grind the workload is reduced by more than 50%, save labor cost, so the price of the epc is relatively low.4
The main reason is: sand mold casting compared with other casting method of low cost, simple production process, short production cycle.So like a car engine cylinder block, cylinder head, curved shaft are of clay green sand casting process.When wet can't meet the requirements to consider using clay sand table dry sand, dry sand mold or other mould.Coatings for green sand mold casting can be from a few kilograms weight until a few jins, dry production of castings and clay can weigh up to dozens of tons.Sand casting obvious advantages, is widely applied in the casting industry.
