ABSTRACT:
Cope and drag molds are formed using a matchplate, in which the matchplate has shift blocks on its upper and lower surfaces. The shift blocks form corresponding cavities in the cope and drag molds. Then, a gauge mechanism is calibrated with a gauge standard. The gauge mechanism generally includes a gauge block, a spring biased arm, and a meter adapted to measure movement of the spring biased arm relative to the meter. The calibrating step is performed by sliding the gauge mechanism into the gauge standard which provides prototypical drag and cope mold surfaces. The gauge mechanism is calibrated by setting the meter to zero when the spring biased arm engages the prototypical cope mold surface. Lastly, the gauge mechanism is inserted into the formed cavities in the actual cope and drag molds such that the gauge block engages the drag mold and the spring biased arm engages the cope mold. The meter measures the amount of movement of the spring biased arm and thus the amount and direction of shift of the cope mold relative to the drag mold.
