PURPOSE:To improve accuracy of a force cutting surface by preventing wear of a slide core by eliminating slide of the slide core, by a method wherein an angular pin and locking block provided on one side of adjoining slide core are made movable and devices for giving a time difference to a movement of the slide core are provided on the angular pin and locking block. CONSTITUTION:When an angular block 1 has become a state of b=0 by sinking until the same attains to the state of the b=0 through bending of a spring 5 while a slide core A4 is kept at a mold clamping state, a locking block A2 receives pressure. A slide core B8 is of structure wherein the same slides by an angular pin B9 and simultaneously with completion of mold clamping the same receives pressure by a locking block B7. A slide core A4 is put between the other slide cores B8 and an overlapped part can perform mold clamping without sliding. Then the title mold is of the structure wherein the overlapped part 16 is put between the slide cores A4, A8 and force cutting of a corner 17 of a molded product is performed reliably. |
