Molding machine for making flaskless molds










Image Number 3 for United States Patent #4537238.

The invention discloses a molding machine for making flaskless molds, which has a minimum of structural component groups and units as well as of control devices and adjusting elements. The machine frame is embodied by a closed, symmetrical frame including hollow side parts which receive the pourable molding material and simultaneously perform the functions of tie rods and guidance for the molding flasks. Molding sand blowing-in openings are disposed on the inner walls of the side parts, and the openings are controlled by molding sand openings in the molding flasks in the manner of a valve slide.
