ABSTRACT:
An apparatus for forming objects from a moldable material such as wax. The apparatus includes upper and lower mold pieces having upper and lower mold cavity halves attached thereto. A lever arm extends from the upper mold piece and is pivotally attached to a linear actuator. The upper and lower mold pieces are pivotably connected to one another. Movement of the linear actuator results in opening and closing of the upper and lower mold cavity halves about the pivotable connection of the upper and lower mold pieces.
