摘要： A multiple cavity injection molding system having at least two single cavity injection molds for forming optical discs. The single cavity injection molds are physically and thermally separated from each other. Each single cavity injection mold has first and second mating portions which are movable between a closed position in which a mold cavity is formed and an open position in which the object is removed from the mold cavity. A resin delivery system is operatively coupled to the first mating portion of each of the single cavity injection molds for delivering resin into each of the two single cavity injection molds, and an ejector system is operatively coupled to the second mating portion of the single cavity injection mold for ejecting the molded disc from the mold cavity.

摘要： A method for operating actuators, such as pneumatic valves, in an injection molding machine especially for CD or DVD discs, or other molded articles. The timing of auxiliary processes (such as blowing air into the mold cavity or applying suction to the molded article in the cavity) is set as a function of the instant of completion of a process in the main sequence of operations (especially, cooling the molded article prior to ejection from the mold). In a set and display section the user sets a preferred time tn for each actuator to operate after, or before, a set completion time T of the main-sequence process (e.g., cooling). The time tn can be negative or positive, so that the various actuators turn on before or after the set completion time. A CPU calculates a starting time T±tn, and keeps the actuators on during a following interval tp. The starting time T±tn may be input to a memory, and output to the respective actuator.

摘要： An ultrasonic injection mold for an optical disk includes a movable die and a fixed die; a disk molding cavity formed between the movable die and the fixed die; a stamper positioned at the bottom of the cavity for forming a pit on a surface of the disk; and an ultrasonic generation device provided on the movable die or fixed die for applying ultrasonic waves to the cavity in performing infection molding. One or more slits are formed on the movable die and the fixed die in the direction which crosses the radial direction of the cavity. The ultrasonic injection mold minimizes the amplitude of the ultrasonic transmitted in the radial direction of the cavity.

摘要： In the method of manufacturing an optical recording medium according to the present invention, when an optical recording medium having at least first and second minute concave and convex surfaces formed thereon is manufactured, the first and second minute concave and convex surfaces are simultaneously molded on both surfaces of a substrate of the optical recording medium. Therefore, it is possible to manufacture a multilayer optical recording medium having an excellent symmetrical structure with respect to a vertical cross section direction of the substrate, i.e., in the thickness direction of the optical recording medium. Moreover, it is possible to effectively suppress the deformation thereof resulting from curing or shrinkage of an light curing resin or the like, absorption or removal of vapor in the air into or from a substrate, a transparent intermediate film or the like, and so on.
