Description

Technical Field

[0001] The utility model relates to the technical field of casting, in particular to a casting taking-out mechanism for manufacturing precision casting sand molds. Background Art

[0002] Precision casting is a general term for the process of obtaining castings with precise dimensions. Compared with the traditional sand casting process, the castings obtained by precision casting are more precise in size and have better surface finish. It includes: investment casting, ceramic casting, metal casting, pressure casting, and lost foam casting. Precision casting is also called lost wax casting. Its products are precise, complex, and close to the final shape of the parts. They can be used directly without or with very little processing. It is an advanced process for near-net-shape forming.

[0003] After the casting is cast from the sand mold, the completed casting needs to be taken out. However, the temperature of the casting is too high at this time and it cannot be taken out blindly. It needs to be taken out with the help of a taking-out mechanism. When taking out the casting, the casting needs to be clamped evenly to prevent damage to the casting due to uneven clamping.
