ABSTRACT:
A core blowing machine receives match plates on a mounting surface so that a sand and bonding agent mixture may be packed about the match plate and exposed to a catalytic gas for forming a mold component. A support surface is disposed beneath the mounting surface. An auxiliary assembly includes an auxiliary mounting surface and an auxiliary support surface in substantially the same spatial relationship as the mounting and support surfaces. A support jack is placed on the auxiliary support surface and is adjusted in length to extend between the auxiliary support surface and a match plate mounted in the auxiliary assembly. Then the suppot jack is placed in a position on the support surface which is similar to the position occupied on the auxiliary support surface and the matching plate is disposed on the mounting surface. Indicia are provided on both the auxiliary support surface and the support surface to aid in placing the support jack in the similar position on the latter surface.
