Description

Technical Field

[0001] The utility model belongs to the field of casting technology, and specifically relates to a combined shell mold for pouring a pump shell casting. Background Art

[0002] With the continuous advancement of casting technology, more and more casting methods have emerged. Among them, shell casting, compared with ordinary sand casting, has the characteristics of less equipment investment, small footprint, convenient production, high production efficiency, less casting sand, less dust and noise on the production site, and thus less pollution to the environment. The produced castings have high surface finish, high dimensional accuracy, and good material properties.

[0003] During use, the existing combined shell mold is usually used to cast one type of pump shell. When casting other types of pump shells, the mold in the shell mold needs to be replaced. When replacing, the previous mold needs to be disassembled, which is cumbersome. When casting the shell mold, the shell mold is usually clamped with a clamp. The lack of fixation during the clamping causes the shell mold to shift due to the change in weight during casting. This phenomenon has become a problem that needs to be solved urgently by people in this field. Utility Model Content
