MOLD CORE-PIN DEFLECTION TRANSDUCER

摘要

A transducer for measuring the amount of lateral deflection taking place at the tip (22) of a core-pin (10) inside a mold (16). The transducer provides a means of determining deflection as it occurs during the molding process for statistical control. A plurality of strain gauges (24, 24') are mounted on the core-pin outside of the mold cavity to provide real time electric signals of lateral deflection that can be used to automatically segregate reject parts and provide for statistical process control. The electric signals are conditioned and manipulated with electronics and firmware to generate real time information corresponding to forces applied to the core-pin and deflections of the core-pin in response thereto. The information produced may be viewed graphically in real time and used to manually or automatically adjust molding parameters and reject out-of-spec products.
