Apparatus for adjusting relative positions of different machine components includes first and second eccentric rings. The first eccentric ring has a first edge disposed in slideable contact with a first component of a given machine, such as an adjustable base section of a cavity mold part. The second eccentric ring has a first edge disposed in slideable contact with a second component of the given machine, such as a stationary side section of the cavity mold part, and has a second edge disposed in slideable contact with a second edge of the first eccentric ring. The contact portions of each said edge are circumscribed by a respective circle. By rotating both eccentric rings the relative positions of the first and second machine components can be adjusted in accordance with desired two-dimensional coordinates.
