Description

Technical Field

[0002] The existing Chinese patent document CN219130682U discloses a sand mold and a sand casting module. It proposes that when two sets of half molds are closed, the first cavity on one half mold corresponds to the second cavity on the other half mold to form two sets of the same type of cavity. Therefore, two sets of castings can be cast at the same time. The two identical half molds increase the replaceability, making it more practical and economical. The two sets of half molds are respectively provided with a first connecting part and a second connecting part, so that two adjacent sand molds can be connected to each other to form a sand casting module, which further improves the casting efficiency.
