ABSTRACT:
Inserts with projections and recesses are provided for securement to mold components and also are arranged to make respective recesses and projections in impression material such as sand. These recesses and projections in the impression material are dimensioned and shaped to have a reverse interfitting engagement to accomplish anti-shift functions and are dimensioned and arranged to form spaces between facing impression portions for receiving loose impression material. This arrangement also forms an improved method of mounting anti-shift inserts.
