Abstract
An automatic pouring method without using a servomotor having a vertical output shaft, establishing the pouring at a low level, eliminating the unstable pouring, sand inclusion, and gaseous defects. An automatic pouring method using a ladle to be tilted for pouring molten metal into a pouring cup of a flaskless or tight-flask mold in at least one pouring device movable along an X-axis parallel to a molding line in which the mold is transferred, wherein the ladle is moved along a Y-axis perpendicular to the molding line in a horizontal plane and is tilted about a first axis of rotation and further about a second axis of rotation.
Claims7
An automatic pouring device for pouring molten metal from a tiltable ladle into at least one mold in a molding line, comprising:
- a lower cart movable along an X-axis parallel to the molding line;
- an upper cart mounted on the lower cart for lateral movement of the upper cart along a Y-axis perpendicular to the molding line and in a horizontal plane;
- a fixed frame fixedly mounted on the upper cart;
- a tilting frame pivotally mounted on the fixed frame about an axis of rotation;
- a first tilting means for tilting the ladle about a first axis of rotation on the fixed tilting frame;
- a second tilting means for tilting the ladle about a second axis of rotation on the fixed frame that differs from the first axis of rotation, and that is located at a position closer to a center of the ladle than is the first axis of rotation, wherein the second tilting means includes the tilting frame and the second axis of rotation is the axis of rotation of the tilting frame;
- and
- an electric control unit having a program for controlling and adjusting the tilt angle of the ladle about the first axis of rotation, and the tilt angle of the ladle about the second axis of rotation without vertically moving the ladle when the molten metal is to be poured.
