て固定金型に位置決めされる。(Function) Since the present invention is constructed as described above, the movable positioning member is initially in a horizontal state due to the eccentric load on the inclined side portion. Then, by placing the workpiece on the fixed mold, the movable positioning member is pressed by the workpiece and swings against the eccentric load on the inclined side, so that the lower end of the workpiece is placed on the flat surface of the positioning mount. At the same time, the edge of the workpiece abuts the abutting portion and is positioned on the fixed mold. In addition, due to the swinging of the movable positioning member, the inclined side of the movable positioning member is approximately aligned with the flat surface of the positioning mount, so when the movable mold is lowered and pressed, the flat surface of the positioning mount is aligned with the movable mold. The workpiece is pressed without getting in the way when pressing with the lower end of the mold. Next, when the workpiece is processed, the edge of the workpiece is reduced closer to the fixed mold than before processing. Then, when the movable mold moves up, the movable positioning member swings due to the eccentric load on the inclined side and becomes horizontal, and the vertical side of the movable positioning member stands up and becomes vertical. As a result, the edge of the reduced workpiece is held down by this vertical side, and the processed workpiece is positioned on the fixed mold by the vertical side of this movable positioning member.

ようになつている。(Example) Examples of the present invention will be described in detail below based on the drawings. First, FIG. 1 shows a press product slippage prevention device 10, and the right half from the center line 11 is a movable mold 12.
The movable mold 12 is in the lowest position fitted to the fixed mold 1, and the left half shows the state in which the movable mold 12 has been raised after processing and the workpiece 2 has been processed. The movable mold 12 has a concave shape to receive the workpiece 2 for molding, and a pad 13 for pressing the upper part of the workpiece 2 is supported at the center by a spring member 14. . An elastic urethane member 15 is attached to the outer surface of the movable mold 12 facing the fixed mold 1, and is shaped to press downward a positioning attachment body 16, which will be described later. On the other hand, the fixed mold 1 has a convex shape corresponding to the concave shape of the movable mold 12, and the outer shape of the workpiece 2 is fitted into a predetermined position at multiple locations around the fixed mold 1. A fixed positioning member 17 and a movable positioning member 18 that holds the edge 3 of the workpiece 2 after processing are attached to the above-mentioned positioning mount 16. Fixed positioning member 17
As shown in FIG. 2, it is made up of a flat plate 19 and a rod member 20 that is tilted and fixed to one side of the flat plate 19 in such a manner that the workpiece 2 can be slid down.
The above-mentioned one side of the flat plate 19 forms a contact portion 21 against which the edge 3 of the workpiece 2 comes into contact. Elongated holes 22, 22 are formed at two locations on the upper surface of the flat plate 19, and the flat plate 19 is adjustably attached to the positioning mounting body 16 with bolts 23. The movable positioning member 18 has a substantially right triangular side surface, and when a load is applied in the direction of the inclined side 24, the movable positioning member 18 rotates, and the shaft 26 is moved somewhat toward the vertical side 25 of the movable positioning member 18. The spacer 27 is rotatably supported by. A stopper 29 is embedded in the pivotally supported spacer 27 at a position where the bottom side 28 of the movable positioning member 18 is horizontal and in contact with the inclined side 24 side. A bolt 32 is inserted into the positioning mounting body 16 through a long hole 31 through a spacer 30 as shown in FIG.
Adjustably tightened by. The vertical side portion 25 is located somewhat closer to the fixed mold 1 than the contact portion 21 of the fixed positioning member 17 . That is, after the forming process, the edge 3 of the workpiece 2 moves inward from the abutting part 21, so the vertical side 25 is provided to abut the moved position. Therefore, the contact portion 21 and the vertical side portion 25 can be freely adjusted depending on the width of the flange portion 33 of the workpiece 2. Returning to FIG. 1, a guide rod member 34 is fixed to the lower part of the positioning mounting body 16, and is inserted into a through hole on the flat surface of the fixed mold 1 via a spring member 35, and is inserted into the through hole of the movable mold 1.
2 is compressed by pressing, and the positioning mount 16 is returned to the predetermined position by its release.

決め保持されるようになつている。 The operation of this embodiment configured in this way will be described next. First, as shown in FIG. 4, the positioning mounting body 16 is supported by the spring member 35 and is positioned at a predetermined height on which the workpiece 2 is placed, and the movable positioning member 18 is positioned at the inclined side portion 24.
It swings due to the eccentric load on the shaft 26 (FIG. 2) and comes into contact with the stopper 29, making it substantially horizontal.
Next, the workpiece 2 is placed on the fixed mold 1 and the movable mold 1
When the movable positioning member 2 is lowered (or due to the weight of the workpiece), the movable positioning member 1, which has been horizontal until now,
8 is pushed by the lower end of the workpiece 2 and swings (first
State on the right side of the figure) The lower end of the workpiece 2 is supported by the flat surface of the positioning attachment 16, and the contour edge 3 of the workpiece 2 is in contact with the abutment part 21 to be positioned with respect to the fixed mold 1. . In addition, the movable positioning member 18
As a result of the above-mentioned rocking, the inclined side portion 24 comes to approximately match the flat surface of the positioning attachment body 16, as shown in the figure on the right side of FIG. The flat surface of the body 16 comes to be pressed. In this way, the workpiece 2 is supported by the flat surface of the positioning attachment body 16, the workpiece 2 is positioned by the abutting portion 21, and the urethane member 15 is in contact with the flat surface of the positioning attachment body 16. So, the movable mold 12
When the positioning attachment 16 is lowered, the positioning attachment body 16 is lowered against the elastic force of the spring 35, and the workpiece 2 is pressed. Movable mold 1 after press processing
2 is raised, the positioning attachment body 16 is raised by the spring 35 and lifts the workpiece 2, and the contour edge 3 of the machined workpiece 2 shrinks and moves toward the fixed mold 1. Therefore, the movable positioning member 18 is aligned with the axis 2 of the inclined side portion 24.
The vertical side 25 oscillates due to the eccentric load on 6.
The edge 3 of the workpiece 2, which has been erected and shrunk as shown on the left side of FIG. 1, comes into contact with the vertical side 25 and is held in a positioned state. In this way, the workpiece 2 is positioned and held before and after the workpiece 2 is processed.
