  • Mold and method for injection-molding a part with a projecting portion
    Patent number: 9221205
    Abstract: A mold and a method for the molding by injection of plastic material of a generally thin part, notably of a vehicle lighting and/or signalling device. The mold comprises two half-molds designed to be disposed one against the other and forming an enclosure designed to be filled with plastic material by injection. The plastic material is injected via an injection nozzle in the vicinity of one end of the part. The volume formed by the mold includes a cavity the volume of which may be modulated by means of a mobile element. During the injection of plastic material, when the latter has reached at least the level of the cavity, the initially zero volume of the cavity is progressively increased via the control means of the mobile element.
