着を枢支構造としてもよい。 A nest holding member 17 is movably fitted into the hollow portion 13, and the nest holding member is provided with a protruding rod 19 that penetrates the stepped portion 15, and a protruding rod 19 is provided at the tip of the protruding rod. The insert 5 is fixedly attached thereto. or,
The movement stroke S of the insert holding member 17 is formed to be larger than the insert mounting depth D of the insert mounting portion 11. In this example, the cavity 13 is formed into a cylindrical shape, and the insert holding member 17 is accordingly formed into an annular shape, while the insert 5 is fixed to the tip of the protruding rod 19. Therefore, the insert 5 is attached to the insert mounting portion 11.
It is rotatably provided at a position protruding from. However, as another embodiment in which the insert 5 is rotatably provided at a position protruding from the insert mounting portion 11, the cavity 13 and the insert holding member 17 are formed into an angular shape, and the insert at the tip of the protruding rod 19 is formed into a rectangular shape. The child 5 may be fixed using a pivot structure.

都合を回避することができる。(Effects of the invention) As explained above, the runner switching device for a molding die according to the present invention has a cavity communicating with the insert mounting part of the mold, and a cavity between which the cavity is connected. A stepped portion having a diameter smaller than the diameter is formed, and an insert holding member is movably fitted in the hollow portion, and the insert holding member is provided with a protruding rod that penetrates the stepped portion. fixing the insert to the tip thereof, forming a movement stroke of the insert holding member to be larger than the insert mounting depth of the insert mounting portion, and mounting an elastic body in the cavity, The insert holding member is biased to protrude in the direction of the insert mounting portion, and the insert is provided so as to be rotatable at the position where the insert protrudes from the insert mounting portion. Once removed, the insert will protrude from the mold due to the elastic force of the elastic body, so pick up the insert and pull it out.
Therefore, the series of operations to rotate it 90 degrees can be performed very simply and easily. Therefore,
Unlike conventional methods, when taking out the insert, there is no need to remove the mold from the molding machine and take out the insert with the insert facing downwards, so the setup time for mold molding can be shortened. . Moreover, in this case, even if the insert is pulled too much, the insert is supported by the insert holding member and will not fall, so it is possible to avoid the conventional inconvenience of dropping and damaging the insert when removing the insert. .
