There is one disclosed in Publication No. 12342.

As shown in FIG. 5, this trimming device 51
is assembled into a machine body 52 for automatic casting or automatic molding. That is, a punch 55 for trimming operation is fixed to a movable part 54 that supports a movable mold 53 in the machine body 52.
Further, a fixed frame 59 is fixed to the fixed part 57 that supports the fixed mold 56 via a bracket 58 that projects outward, and the fixed frame 59 has a guide hole for discharging the product that is aligned with the punch 55. 59
a is formed.

Furthermore, a cylinder 60 is attached to the fixed frame 59.
A gripper 61 is provided at the tip of the piston rod 60a. Based on the operation of the cylinder 60, the gripper 61 moves in a direction substantially perpendicular to the moving direction of the movable part 54.
A trimming position aligned with the punch 55 and the guide hole 59a as shown by the solid line in FIG. 5, and a gripping position where the product W is gripped between the molds 53 and 56 as shown by the two-dot chain line It is now possible to move back and forth between the two.

The gripper 61 constitutes at least a part of a die of a trimming press, and the gripper 61
The reciprocating motion of the movable part 54 is controlled in relation to the mold opening operation, and the gripping device 61 is moved forward to the gripping position, thereby removing the product W cast between the two molds 53 and 56.

[Problems to be Solved by the Invention] However, the conventional trimming device 51 was not provided with any means for adjusting the positioning with respect to the molds 53 and 56. Therefore, when replacing the molds 53 and 56 supported by the movable part 54 and the fixed part 57 with molds for another product, the center position of the replacement mold and the center of the gripper 61 are In order to align with the position P, the only option was to position the mold side so as to align it with the arrangement of the gripper 61.
Therefore, the movable part 54 and fixed part 5 of the machine body 52
In No. 7, the heavy mold had to be positioned by delicately adjusting its displacement in the vertical and lateral directions, and the work was large-scale and troublesome.
Furthermore, in order to precisely position the mold with respect to the movable part 53 and the fixed part 57, it is necessary to strictly unify the standard shape of the mold.

This idea was made in view of the above-mentioned circumstances, and was made by focusing on aligning the gripper side with the arrangement of the mold in order to align the center position of the mold with the center position of the gripper. It is an object of the present invention to provide a trimming device that can be freely set and positioned with respect to a mold.

[Means for solving the problem] In order to achieve the above object, this invention includes a support bracket assembled to the machine body,

A product gripper configured to perform a trimming operation in alignment, a first adjusting means for adjusting a moving end position adjacent to one mold in a reciprocating direction of the product gripper, a support bracket and a guide frame. A second adjustment means is provided between the support bracket and the guide frame, and a second adjustment means is provided between the support bracket and the guide frame, and the second adjustment means is provided between the support bracket and the guide frame, and adjusts the positions of the two by displacing the product gripper in a direction perpendicular to the reciprocating direction of the product gripper. A configuration is adopted in which a third adjusting means is provided for adjusting the position by rotationally displacing the support bracket and the guide frame in the same plane as the direction of displacement of the support bracket and the guide frame with the position on the mold side as the rotation center.

[Operation] Therefore, the first adjusting means adjusts the moving end position close to both molds in the reciprocating direction of the product gripper. and the second adjusting means displaces the support bracket and the guide frame relative to each other;
As a result, the reciprocating direction of the product gripper is displaced in a direction perpendicular to the reciprocating direction, and the position of the product gripper is adjusted. Further, the third adjustment means causes the guide frame to be rotationally displaced about the position on both mold sides in the same plane as the displacement direction of the support bracket and the guide frame based on the second adjustment means. As a result, the reciprocating direction of the product gripper is rotated about the positions on both mold sides, and the position is adjusted.

In this way, the arrangement of the product gripper is aligned with the arrangement of the mold in order to align the center position of the product gripper with the center position of the mold. As a result, there is no need to adjust the displacement of the heavy mold, and the position adjustment operation can be easily performed.
