<p>Provided is a mold aligning apparatus for making the center axes of a pair of molds coincide precisely with each other. A position-determining sensor (70) is installed on a movable mold (41). Thereby the position of the movable mold (41) relative to the fixed mold (42) can be measured precisely, even when positional deviation occurs between the movable mold (41) and a mold-mounting plate (44) supporting the movable mold (41). Further, in the operation of closing the movable mold (41) with the fixed mold (42), the mold-aligning plate (51) is controlled so as to bring the output of the position-measuring sensor (70) to a prescribed level regarding the three axis directions of X-direction, Y-direction, and ?-direction, making the center axes of the movable mold (41) and the fixed mold (42) coincide precisely in mold clamping. Thereby, the reproducibility of properties of the molded products are improved.</p> |
