ABSTRACT:
A mold base kit including plural plates having alignment bores for receiving guide dowels for accurately aligning the plates with respect to one another as a mold frame is assembled from the kit. Each guide dowel includes a hollow, cylindrical sleeve sized to fit snugly in the alignment bores of adjacent, abutting plates and also includes an abutment member extending radially outwardly of the guide dowel sleeve intermediate its ends which prevents the guide dowel from moving a substantial distance along an alignment bore. The abutment member may be formed by a circular piece of spring wire which extends through an arc of more than 180.degree. around the outside of the dowel sleeve, and preferably approximately 270.degree. around the sleeve. Because the retainer clip extends less than completely around the sleeve, its ends can readily be spread apart for assembly of the retainer clip onto the sleeve.
