Description

Lost foam sand box for casting automobile parts

Technical Field

The utility model relates to a disappearance mould especially relates to a casting of automobile parts is with disappearance mould sand box.

Background

The lost foam casting is a novel casting method which comprises the steps of bonding and combining paraffin or foam models with sizes and shapes similar to those of castings into model clusters, coating refractory paint on the model clusters, drying the model clusters, burying the model clusters in quartz sand stones for vibration molding, casting under negative pressure to enable liquid metal to occupy the positions of the models, and solidifying and cooling the liquid metal to form a gradual casting. When the conventional lost foam sand box for casting automobile parts is used for casting, a drainage tube is directly communicated with a casting, so that the casting speed is too high, carbon slag is formed to influence the melting of liquid metal, and the forming effect of the casting is influenced. After the casting is formed, the casting is often manually taken by using a tool, and damage to the casting opening can be caused in the process of taking the casting. After the casting work is finished, the sand and stone are replaced manually, the situation that personnel are scalded can occur due to the residual heat of the side wall, and the working time is wasted.
