    摘要: The present invention provides an apparatus for shaping deformable materials during molding processes. The apparatus includes a vibrating wall assembly which fits the contours of at least a portion of a mold's cavity. The vibrating wall assembly includes a pliable wall (30, 32, 34) positioned within the mold (21). The pliable wall (30, 32, 34) is positioned such that its outside wall surface (38, 42, 46) is adjacent to a portion of the mold's inside wall surface (36, 40, 44); and its inside wall surface (36, 40, 44) defines a portion of the geometric configuration of the material passing thereover. The pliable wall (30, 32, 34) is designed to deform from its original shape when a positive or negative pressure is exerted on its inside or outside wall surface. This positive and/or negative pressure is generated, at least in part, by the displacement of a displaceable fluid. This fluid is contained within a chamber (48, 50, 52) which is in communication with a portion of the pliable wall's outside surface (38, 42, 46).

    摘要: An ultrasonic-assisted injection molding system and method for making precisely- shaped articles. A source of ultrasonic energy is positioned to apply vibrational energy to a mold cavity connected to at least one gate in flow communication with a source of molten (co)polymer. The mold is heated to a temperature of 104-116°C, and the molten (co)polymer is injected into the mold cavity. After cooling the mold until the molten (co)polymer within the gate has solidified, ultrasonic energy is applied to the mold without remelting the solidified (co)polymer within the gate until the temperature increases to 116-122°C, thereby substantially relieving flow induced stresses. The mold is then cooled until the temperature decreases to 101-107°C, and is thereafter heated until the temperature increases to 116-122°C, thereby substantially relieving any thermally induced stresses. The mold is cooled until the molten (co)polymer has solidified, thereby forming a precision molded plastic optical element.

    摘要: A semi-solid mixture of noncomestible material is brought into contact with a virbrating surface of a mold (113) including two vibrating tools (108, 110) each having a cavity (111) therein, whereby energy is transported across the surface into the mixture to form a molded cylindrical shape (112). The mixture is injected into the mold (113) from the side through a port defined by surfaces (115) after the two vibrating tools (108, 110) are brought together. The vibration is generally in the ultrasonic frequency range, and the energy injection is sufficient to cause local physical and chemical changes in mixtures susceptible to such changes, and generally to cause changes in the direction of increased tensile strength and resistance to flow. In general, a skin is formed on the mixture, and with greater processing efficiency then if such skin were formed by purely thermal means.
