<p>Plastic parts are molded in an apparatus having two molds mounted on a reciprocating shuttle bed. While one mold is filled with resin at a filling position, the other mold is at an unloading postion where a part cools and is extracted. The bed is then shuttled so that the other mold is at the filling position and the one mold is at a second unloading position. The molds have separable mold halves closed by a suitable driver. A toggle mechanism engages latches on the mold halves to lock the mold closed. The toggle is a pair of pivoting leaves on a transversely movable post. The edges of the leaves separate and engage stops on the latches. An extrusion head advances to the mold for filling and is withdrawn for shuttling. A part extractor is movable between the unloading positions and places the parts in a bin.</p> |
