Jewelry or tooth-crown molding device

Claim 1

A molding device utilizable with a dental or jewelry plasterforming cylindrical tube and base having a central upper opening therein, comprising in combination: a first male insert means comprising a formed low-melting point composition and including a male insert projection having a laterally-outwardly facing wall and extending longitudinally axially and the male insert projection being of a predetermined cross-sectional size suitable for mounting of the projection within the base central upper opening, the male insert means further including a head structure defining a plurality of laterally-upwardly directed receptacles such that said receptacles are each receivable of a wax-stem end in a manner supportable of the stem axis in a laterally-upwardly direction, said head including an outwardly facing wall structure extending substantially axially to said male-insert projection, and the wall structure at a base thereof including a shoulder defining an inner-extremity stem-end receiving-space of each of said receptacles, said shoulder being spaced laterally-outwardly a predetermined distance greater than the laterally-outward location of the male insert projection laterally outwardly facing wall, such that upon inserting the stems and upon thereafter forming a hardened plaster cast around the male insert means, and upon inverting the plaster cast and upon melting-removing the composition from the plaster cast, each stem passage is laterally off-set from the molten-metal inlet axial passage resulting from the cast around the male insert projection.
