Abstract:
A workpiece manufacturing apparatus includes a punch, which is provided in a lower die assembly and punches out a workpiece from an unprocessed material, and an ejector, which is provided in an upper die assembly so as to be capable of approaching and moving away from the lower die assembly. 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.

Claim (Index 2):
The workpiece manufacturing apparatus according to  claim 1 , wherein\n the ejector and the slider are provided in the upper die assembly, a roller is provided above the ejector, the roller being coupled to the ejector to be capable of moving integrally with the ejector, the roller is in contact with the slider by an urging force of the spring acting on the ejector, the slider slides in a horizontal direction between the locking position and the releasing position, the slider includes\n a releasing surface, which contacts the roller when the slider is in the releasing position, \n a locking surface, which is located at a higher level than the releasing surface, the roller contacting the locking surface when the slider is in the locking position, and \n a slope, which connects the releasing surface and the locking surface with each other, \n when the slider is in the locking position, the roller is pressed by the locking surface to compress the spring, thereby locking the ejector with respect to the upper die assembly, and when the slider is in the releasing position, the releasing surface is caused to contact the roller to weaken the urging force of the spring as compared with that during the compression, thereby releasing the ejector.
