    摘要： A die having a plurality of cavities and a temperature sensor for acquiring a temperature value in which the number of the cavities is larger than that of electrothermal conversion elements. When viewed from a direction perpendicular to the surface of a parting line, all cavities and a temperature sensor are arranged in a region occupied by the electrothermal conversion elements. Interval between the outlines of the cavities is smaller than the minimum interval between the outline of the cavity and the electrothermal conversion element, and the shortest distance between the electrothermal conversion element and the temperature measuring portion of a temperature measuring element is shorter than the minimum interval between the outline of the cavity and the electrothermal conversion element.

    摘要： An apparatus for molding optical components of a small size and high precision is provided with good transferability and a reduced production cycle. This apparatus includes a plurality of runners arranged in a pattern allowing multi-cavity molding for molding plastic lenses each having an outer diameter of 2 mm to 12 mm and surface roughness Ra of 20 nm or less. The total projected area of the runners is determined within a range of 1 cm2 to 12 cm2. The runners are arranged to extend around a sprue in directions perpendicular to an outer surface of the base molds. The pattern of the runners extending from the junction with the sprue to each shape transfer section is configured in two intersecting directions. A cavity is of a rectangular outer shape when seen from a pressure contact surface side.

    摘要： An injection molding comprises: a fixed mold; a movable mold which is capable of contacting to and separating from the fixed mold; and an injection unit which supplies molten resin to a space formed between the fixed mold and the movable mold when being pressed to a non-molding face of the fixed mold. The injection unit comprises: a nozzle portion which injects molten resin to the space formed between the molds; an injecting portion which applies molten resin pressure toward the space formed between the fixed mold and the movable mold though the nozzle portion; a heater and a temperature sensor provided on the nozzle portion; and a heater and a temperature sensor provided on the injecting portion, and detection accuracy of the sensor of the nozzle portion is higher than that of the injecting potion. There is thus provided an injection molding machine capable of manufacturing optics with high accuracy without considerable cost-up by realizing stable and highly accurate injection.
