摘要： A molding machine includes a fixed mold and a movable mold. The molding machine is a so called micro molding machine which provides less than 150 KN of the mold clamping force for clamping the fixed mold and the movable mold. A positional shift length between both molds is preset at ±20 gm or less. Further, cavities are inserted in base molds of both molds respectively. Furthermore, cores are inserted in the cavities. The position of each cavity is adjustable with respect to each associated base mold. The position of each core is also adjustable with respect to each associated cavity. Moreover, the molding machine can simultaneously mold a plurality of optical components.

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 projected area of the entire runner 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 mold and an injection molding apparatus having a movable mold and a fixed mold. Each of the movable/fixed molds has bases, and a runner, a gate and a cavity are formed. The gate is composed of recesses made in mutually opposite end surfaces of sleeve-like heat insulators provided for the bases. Thereby, the gate is heat-insulated, and resin in the gate is prevented from cooling down during a pressure retention step. Thus, the resin keeps fluidity longer.

摘要： An injection mold composed of a movable mold and a fixed mold. The movable mold has bases, a heat insulating layer and a surface processed layer, and the fixed mold has a base. A heat insulator is provided on the inner circumferential surface of the base of the movable mold at a part forming a wall of a cavity. The heat insulating layer is in the rear of the surface processed layer, and therefore, the transfer accuracy of a fine configuration of the surface processed layer is improved. Additionally, since the heat insulator is provided adjacent to the fine configuration, heat radiation from resin is inhibited, and the transfer accuracy of the fine configuration is further improved.

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.
