Description

Technical Field

[0001] The utility model relates to the technical field of molding machines, in particular to a casting sand mold compacting molding machine. Background Art

[0002] A molding machine is a type of casting equipment used to create sand molds. Its main functions include filling, compacting, and demolding. During processing, as the sand enters the flask from the shot jar, it becomes concentrated at the flask's sand inlet, creating a hilly, uneven thickness.
