Abstract

The invention is suitable for the technical field of glass compression molding, and discloses optical precision aspherical glass compression molding equipment. The optical precision aspherical glass compression molding equipment comprises a frame, a mold device, a heating device and a driving device, wherein the mold device is arranged in the frame; the heating device is arranged in the mold device; the driving device is arranged below the mold device, and is used for driving the mold device to realize mold assembly or mold sinking; the heating device comprises an internally-hollow quartz cover, a radiation screen arranged on the quartz cover in a sleeving way, a plurality of layers of heating tubes which are annularly arranged on the outer side of the quartz cover and are fixed to the radiation screen, a heat insulating layer arranged on the outer side of the radiation screen in a sleeving way, and a furnace wall arranged on the outer side of the heat insulating layer in a sleeving way and is fixed to the heat insulating layer. The heating device has high stability and reliability, and can be used for heating glass blanks rapidly; the radiation screen of the heating device reflects medium-long waves of infrared thermal radiation emitted by the heating tubes, and heat energy can be gathered together through the arc shape of the radiation screen; heat exchange among interfaces can be reduced effectively through the heat insulating layer of the heating device.

Description

technical field [0001] The invention belongs to the technical field of glass compression molding, in particular to an optical precision aspheric glass compression molding equipment. Background technique [0002] Projectors, digital cameras, mobile phones and other devices that use precision glass lenses can be seen everywhere in our lives. With the continuous development of manufacturing technology in recent years and the market demand for lighter, thinner and shorter products, lighter and thinner aspheric mirrors are widely favored compared with spherical mirrors. [0003] In order to facilitate high-volume processing and reduce costs, many glass lenses are processed from polymer materials. Compared with polymer material lenses, glass lenses have advantages in many aspects: First, glass lenses have a higher refractive index and a wider light transmission spectrum range, which is suitable for making thinner lenses with high imaging quality; Second, the glass lens has high ...
