ABSTRACT:
The present invention is directed to a toy molder/extruder which is used for cold molding and/or cold extruding of clay dough with the use of toy molds and toy dies. This toy has a main housing with a base, an upright middle section and a top. A pinion gear is rotatably located at the top of the housing and a crank wheel and handle is connected to the pinion gear to enable the user to rotate the pinion gear. A ram piston with a rack gear is attached to the main housing with the ram piston being connected to the top of the housing in a vertically movable fashion, so as to engage the rack gear and the pinion gear with on another. The toy also has a compression chamber with an open top which is connected to the housing and located below the ram piston. It has a cross-sectional dimension adequate to allow ram insertion of the ram piston and has a tapered bottom with an outlet orifice substantially smaller than the compression chamber's open top. The toy also includes a clamping means connected to the housing and located below the compression chamber so as to hold a mold or die for receiving clay dough by ram action compression-injection.
