Description

Technical Field

[0001] The utility model relates to the technical field of casting production, in particular to an automatic production line for producing castings by using lost foam. Background Art

[0002] Lost foam casting is a new casting method in which paraffin or foam models with similar size and shape to the casting are bonded together into a model cluster, coated with refractory paint and dried, and then buried in dry quartz sand for vibration molding. The model is poured under negative pressure to vaporize the model, and the liquid metal occupies the position of the model. After solidification and cooling, the casting is formed. After the lost foam casting is completed, the casting needs to be taken out from the quartz sand. After the casting is completed on the existing lost foam production line, a small amount of quartz sand will remain on the surface of the casting without falling off, and there is residual temperature after molding that has not been dissipated, which makes it inconvenient to store the casting and carry out the next step of processing. The casting needs to be cleaned manually, which is time-consuming and labor-intensive.

[0003] After searching the existing public patent number: CN202221848177.3, the public patent name is: a separated lost foam casting production line, which belongs to the field of lost foam casting technology.
