Precise positioning of casting system - above mould sprue in boxless mould making and conveying

摘要

In a process for positioning the bottom pouring hole of a casting system above the sprue of a mould in boxless mould making and converging system the pouring hole position above the sprue is inspected and position errors are detected, as soon as a mould making and conveying operation is ended and the mould is at rest. The positioning equipment includes (i) a measuring system (19) for determining the pouring hole (14) position above the sprue (10); (ii) a positioning system (18) for longitudinal and transverse adjustment of the casting system (12) w.r.t. the conveyor system (11); and (iii) a measurement processing system (20) for controlling the positioning system (18). USE/ADVANTAGE - The process is useful in the casting of metal articles in boxless moulds. it allows casting to be carried out without delay and compensates for tolerances in the mould thickness and within the conveyor system for rapid and precise pouring hole positioning.
