ABSTRACT:
A blowing sand molding machine includes a main frame to the top of which is mounted a hopper for storing sand, which hopper, at a given moment, is vertically aligned with a corresponding blowing cartridge which receives a portion of the sand so that by means of a current of pressurized air blown into the cartridge the sand passes therefrom to master plates fixed to appropriate supports. Longitudinally disposed on the main frame and below the blowing cartirdge, a pair of cylindrical bars acting as guides for the supports of the master plates, the bars or guides extending along the front and rear zones of the machine. The bar of the front zone occupies a substantially lower plane than that occupied by the bar of the rear zone. One master plate support is moved along the guides by means of a manually operated wheel, while the other support is moved along such guides with the help of a pressure cylinder. Between the outlet of the blowing cartridge and the master plates there is installed a gassing plate displaceable horizontally and alternatively by another pressure cylinder. Between the pressurized air duct and the blowing cartridge there is arranged a sealed coupling device flexible in a vertical direction.
