ABSTRACT:
The separation of a lower mold from an upper mold in an injection molding machine is either temporarily paused or carried out at a lower speed so as to maintain deformation of a thin component within a permissible range, while a jet of air is applied to help remove the thin component from the upper mold. Also, the ejecting operation of the thin component is either temporarily paused or carried out at a lower speed before the deformation of the thin component exceeds the permissible limit while a jet of air is applied to help remove the thin component from the lower mold.
