A flask for containing mold sand within it prevents any mold shifting or mold dropping. Each of an upper flask 2 and a lower flask 3 includes a body that defines an opening in which a sand mold is to be molded. The body has at least one inlet 101 for introducing the mold sand into the opening. Two flanges 102 are 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 flask 104 and a lower flask 105 are opposed to each other across a pattern plate 107. They are integrally assembled to make a flask unit by means of a pair of connecting rods 106 that are fitted in each bore.

Machine for the production of sand molds comprising a machine structure with a molding chamber (3), a front plate (1) and a rear plate (2). The front plate (2) and rear plate (3) are arranged for pressing sand within said molding chamber so as to form a sand mold, and are arranged for receiving respective pattern plates (200) for providing front and rear surfaces of the sand mold with corresponding patterns. The machine further comprises a robot arm (6) arranged for replacing the pattern plates (200), said robot arm being (6) attached to the machine structure, such as to a side (101) of the machine structure.

An arrangement for use in the production of a separable casting mold, preferably of a vertically separable casting mold is disclosed. The arrangement can include (i) a mold plate and/or a mold pattern, (ii) a feeder system having a feeder element and having a feeder insert, wherein feeder element and feeder insert delimit a feeder cavity for receiving liquid metal. The arrangement also includes one or more tipping prevention elements which are designed to counteract tipping of the feeder system out of the opening axis about the first end of the feeder element when, in the event of the feeder system being acted on with a force acting parallel to the opening axis and in the direction of the first end, the side wall deforms and the spacing between the first and second ends is reduced, wherein the one or more tipping prevention element(s) are/is spaced apart from the opening axis.
