ABSTRACT:
A device for detecting a gate in an automatic pouring machine for casting which is located in the vicinity of a horizontal pouring line provided thereon with a plurality of adjacently placed molds intermittently conveyed in one direction and which has a pouring trough provided with a spout for pouring molten metal into the gate of each of the molds and horizontally swingable by a vertical pivot. The device comprises a means provided in each mold to indicate the position of the gate, an arm horizontally swingably mounted by a vertical pivot which is symmetrically placed against the pivot of the trough with respect to the pouring line, a pair of slits provided in ends of the arm and the trough which are opposite with each other upon linear alignment of the arm and the trough, a connecting pin slidably engaged in the slits to move along a perpendicular bisector on a line connecting the two pivots with each other and a photoelectric switch provided in the arm to detect the means for indicating the position of the gate. The distance between the photoelectric switch and the connecting pin becomes identical with that between the connecting pin and the spout of the trough upon linear alignment of the arm and the trough, and a driving means for moving the connecting pin operates upon receipt of a signal from the photoelectric switch to swingingly move the trough and the arm so that the spout is aligned with the gate for certain pouring operation.
