Claims

[Scope of utility model registration request]

In machines that process a workpiece by rotating it one pitch at a time, there is a fixed type in which a rotatable indexing board is provided and the workpiece is set so as to rotate integrally with the indexing board, and a fixed type in which the workpiece is set to rotate integrally with the indexing board. a movable mold that is provided to reciprocate in the direction toward and away from the indexing plate and processes the workpiece in cooperation with the fixed mold; a gear portion that is provided on the indexing plate and has a large number of teeth formed in the circumferential direction; a slider provided on the fixed mold so as to be able to reciprocate in a direction along the rotational direction of the indexing plate; a transmission mechanism that converts the reciprocating motion of the movable mold into a reciprocating motion of the slider; and teeth of the gear portion on the slider. When the slider, which is removably pivoted to the movable mold and is linked to the movement of the movable mold in a direction in which it comes into contact with the fixed mold, moves forward, it disengages from the teeth and moves in a direction away from the fixed mold of the movable mold. a feed pawl that engages with the teeth during the backward movement of the slider that is linked to the movement and rotates the indexing board in one direction; and a feed pawl that is provided on the fixed mold so as to be removable from the teeth of the gear portion and is rotated by the feed pawl. 1. A press mold with an indexing device, comprising a stopper mechanism that stops the rotation of the indexing board after it has been rotated by a predetermined angle and holds the indexing board at the stopped position.
