The manufacturing apparatus further includes a spring, which is provided in the upper die assembly and urges the ejector toward the lower die assembly, and a locking device, which locks the ejector with respect to the upper die assembly at a position at which the punch punches out the workpiece and releases the ejector when the die assemblies are opened. The locking device includes an actuator, which is provided in the upper die assembly and slides a slider between a locking position, at which the ejector is locked, and a releasing position, at which the ejector is released.
