Abstract
An apparatus and method for detecting the misalignment of cooperating mold sections is provided. The apparatus and method utilize a mold making machine which includes a device for forming a cavity of predetermined shape in the interior of each mold section and a device for forming a reference mark on the exterior of the mold surface, a conveyor for transporting the molds along a predetermined path from the mold making machine to a mold pouring station, and a non-contact distance measuring device for detecting the misalignment of the internal mold cavities of the mold sections by detecting any misalignment in the external reference marks.
