Abstract:
In a machine for filling molds with molten metal, a method for controlling pouring position of a pouring machine based on an actual thickness of each mold section, comprising:fabricating a series of cooperating mold sections, whereby two cooperating mold sections define in respective contact regions a mold cavity, each mold cavity having a recessed pour cup on an upper side thereof arranged for receiving molten metal;measuring a length of each last fabricated mold section upon fabrication thereof;moving the series of cooperating mold sections downstream along a predetermined path of travel to a mold pouring station having a pouring machine, the pouring machine being movable longitudinally along the path of travel;calculating a length difference between a mold section lying immediately upstream of the pouring machine in the pouring station, and the last fabricated mold section in the series;moving the pouring machine from its previous pouring position through a distance that corresponds to said length difference such that the pouring machine is placed in alignment with an anticipated final position of a pour cup of a next mold to be advanced into the pouring station.
