The fixed insert 03 is mainly used for being connected with the lower die 02 to stably support the movable insert 04 and the limiting insert 05, and provides stable support for the movable insert 04 and the limiting insert 05. In order to ensure the stability of the fixed insert 03 and the installation accuracy of the fixed insert 03, the fixed insert 03 and the lower die 02 need to be accurately matched.

In this embodiment, a fixing notch 31 is formed by recessing one side of the fixing insert 03, which is in contact with the lower die 02; one side of the lower die 02, which is in contact with the fixed insert 03, protrudes outwards to form a fixed bulge 22; the fixing notch 31 is engaged with the fixing projection 22.
