Abstract
PURPOSE: To fix an insert to a plastic forming by a methd wherein a half-finished product is provided by the use of specific upper and lower dies and before the half-finished product held between the upper and the lower die finishes cooling the insert is forced into the half-finished product.
CONSTITUTION: An upper die 5 provided with a vertically movable upper punch 10 and a lower die 6 provided with an inner punch 12 and an outer punch 13 which are both vertically movable are used. When the upper die 5 is located at the least upper bound, an insert 17 is set-into a cavity provided by dropping the inner punch 12 of the lower die and on the other hand, heated material is supplied into the lower die 6. Then, the upper die 5 is let to fall, the mateial is compressed to provide a formed part 22 and then before the formed part 22 finishes cooling, pressure oil is supplied into the oil chamber of the lower die 6, the inner punch 12 and the outer punch 13 are elevated and the insert 17 is forced into the formed part 22. Then, after cooling is completed, the formed part 22 is taken out, the material scum 23 attached to the upper side of the insert 17 is removed to obtain a finished product.
