Abstract
A flask for containing mold sand within it prevents any mold shifting or mold dropping. Each of an upper flaskand a lower flaskincludes a body that defines an opening in which a sand mold is to be molded. The body has at least one inletfor introducing the mold sand into the opening. Two flangesare extended from the body such that they are opposed to each other across the opening. Each flange has a through bore. The flask also includes engaging members for engaging an actuator in the outside of the flask such that a force or forces from said actuator could be transmitted to the flask. An upper flaskand a lower flaskare opposed to each other across a pattern plate. They are integrally assembled to make a flask unit by means of a pair of connecting rodsthat are fitted in each bore.
