ABSTRACT:
A flask for producing sand-cast parts. To make unpacking of the cast parts easier and to achieve closer measurement tolerances on the same, baffle plates are provided in at least one part of the conical outside, which baffle plates can be tilted out or opened and project in the tilted-in or closed position inside of the flask. These have during the casting process the function of reinforcing the sand portions. After tilting out gas can escape and can be removed.
