The invention provides a mold which comprises a pair of clamp jaws, and a dumpling wrapper filled with fillings can be extruded to have a shape of a dumpling semi-finished product by closing the pair of clamp jaws. Thereinto, the pair of clamp jaws in a closed state can simulate a human action of manual extrusion of a dumpling filling capsule under the action of external force. . The invention also provides an extruding device for driving the mold action, and the extruding device can apply external force with the pair of clamp jaws being in a closed state so as to drive the pair of clamp jaws to perform the simulated human action of extruding a dumpling filling capsule with both hands.
