Abstract
A horizontal stack foundry molding machine having opposed high pressure horizontally aligned rams adapted to close and then move into the open ends of a mold box filled with sand to make a high quality sand mold, such box being formed by opposed L-shape parts, the L-shape part forming the lower side of the box being horizontally movable after the rams have been retracted to shift the mold formed in the box from between said rams to a position in alignment with a pouring conveyor, a pusher being provided to move such mold from the movable L-shape part onto the pouring conveyor into juxtaposition with previously formed molds to form the horizontal stack.
Claims22
A horizontal stack foundry molding machine comprising an open ended box, means to close the open ends of said box and form a mold therein, said box comprising a stationary top and side wall, mans to horizontally move the opposite side and bottom wall, and means to maintain said bottom wall in a position to support such mold during its course of horizontal movement.
A horizontal stack foundry molding machine comprising an open ended box, means to form a foundry mold in said box, and means to shift the bottom and one side wall only of said box laterally to move the mold into alignment with a support for a horizontal stack of such molds.
A foundry molding machine comprising an open ended box having a top, bottom and side walls, means to form a foundry mold in said box by moving a ram into at least one end of said box, and means to open said box after said ram has been retracted by moving the bottom and one side wall diagonally away from the opposite walls, and means to shift said mold horizontally after said box is opened.
A foundry molding machine comprising an open ended box having a top, bottom and side walls, means to ram a foundry mold in said box by moving a ram into at least one end of said box, means to open said box after said ram has been retracted by moving the bottom and one side wall diagonally away from the opposite walls, and means to shift said mold horizontally after said box is opened, said means to open said box after said ram has been retracted by moving the bottom and one side wall diagonally away from the opposite walls comprising a fixed cam and roller means, said fixed cam extending in the direction of diagonal movement desired.
A foundry molding machine comprising an open ended box having a top, bottom and side walls, means to ram a foundry mold in said box by moving a ram into at least one end of said box, means to open said box after said ram has been retracted by moving the bottom and one side wall diagonally away from the opposite walls, and means to shift said mold horizontally after said box is opened, said means to shift said mold horizontally comprising a carriage supporting the bottom and one side wall of the mold box, said means to open said box after said ram has been retracted comprising roller means on said carriage and fixed cam means operative diagonally to raise and lower said bottom and one side wall of said mold box.
A horizontal stack foundry molding machine comprising an open ended box, means to close the open ends of said box and form a mold therein, said box comprising a stationary top and side wall, means to horizontally move the opposite side and bottom wall, means to maintain said bottom wall in a position to support such mold during its course of horizontal movement, and means to raise and lower said opposite side and bottom wall as they move adjacent the fixed top and side wall, said last mentioned means comprising fixed cams and movable rollers, said rollers being mounted for movement with the opposite side and bottom wall.
