Abstract
A foil-decorating injection molding machine is provided with an injection mold having a male mold and a female mold. The female mold has a cavity surface for forming a cavity, and a parting surface having an outer peripheral section on which to hold a decorative sheet, and an inner peripheral section extending between the inner edge of the outer peripheral section of the parting surface and the edge of the cavity surface in a concavely curved shape to allow the expansion of a peripheral portion of the decorative sheet around a decorating portion of the same during preforming. This reduces local strains in the decorative portion of the sheet and ensures a uniform thickness distribution of the sheet to prevent breaking and creasing of the sheet.
