    If it's a water bond sand, it may be a bit too wet.  If it's an oil
    bond, or delft "clay", what may be happening is that loose sand is
    getting knocked into the impression when you pour your material in. 
    You may simply need to pack your frame a little more robustly, and
    use a tube to blow any loose bits from cutting your vents and gates
    away.
