Abstract
Mold dumping apparatus. Means are provided for dumping excess slip from a mold after desired wall thickness of greenware is obtained. Clamp structure is arranged on a first pair of uprights which latter are both vertically and pivotally movable on a pivot axis with respect to a second pair of uprights. Said second pair of uprights are supported rigidly on a base. The mold is received within said clamp structure and the mechanism operated to lift the first pair of uprights upwardly with respect to the second pair thereof. As same reaches a substantially predeterminable point near but above the point of the above-mentioned pivot axis, same becomes overbalanced and will automatically tip and dump the excess slip out from the mold. Any suitable receptacle may be provided for receiving said slip as it flows out of the mold.
Claims6
In a device for dumping a liquid from a mold, such as for dumping slip from a mold, the combination comprising:
- support structure comprising a base and a pair of upstanding support posts positioned rigidly thereon;
- lift structure comprising a pair of parallel arranged lifting posts connected in vertically movable, and pivotal, relationship with said support posts and including clamp means for holding a mold on and between said lifting posts;
- operator controllable means for lifting said lifting posts with respect to said support posts, and pivot means fixedly mounted on said support posts constantly maintaining said pivotal relationship between said lifting posts and support posts;
- whereby so long as the center of gravity of said support posts and the means associated therewith is below the pivotal axis of said pivot means a mold held within said clamp means will remain in liquid holding position but upon lifting of said support structure above said axis such mold will be automatically dumped.
