摘要：An engine block mold package is assembled from resin-bonded sand cores in a manner that reduces parting lines on the exterior surfaces of the mold package. An assembly of multiple cores (core package) is formed and includes multiple inter-core parting lines extending in different directions on exterior surfaces of the core assembly. The core package is disposed between a base core and a cover core configured to enclose the core package and form a single continuous exterior parting line about the assembled mold package.
