Expanding type optical telescope lens upper die device

Abstract

The invention relates to the field of optical telescopes, in particular to an expanding type optical telescope lens upper die device. The technical problem is to provide the expanding type optical telescope lens upper die device. According to the technical scheme, the expanding type optical telescope lens upper die device comprises a mixing assembly, an upper die assembly, a stacking assembly and the like. The mixing assembly is fixedly connected with the upper die assembly. The upper die assembly is fixedly connected with the stacking assembly. When the device is used, the resin and the light conversion powder are automatically and alternately injected into a container in advance, so that the light conversion powder is relatively uniformly distributed in the resin when no stirring operation is performed, the mixing efficiency is greatly improved, meanwhile, the injection head is slowly separated from the die while performing glue injection operation, the die is fully filled with the resin, the phenomenon that the resin at the opening of the die is uneven due to wrinkling of a sealing belt is avoided, and meanwhile, the phenomenon that the rear part of the sealing belt is gathered can be prevented.

Description

technical field [0001] The invention relates to the field of optical telescopes, in particular to an expansion-type optical telescope lens upper mold device. Background technique [0002] In the prior art, one of the optical telescope mirrors is made of powder grinding, mixing, upper mold, molding, lower mold and reprocessing. When the existing device mixes the resin and the light conversion powder, it directly converts the light Pour the powder onto the surface of the resin and then stir, and the resin has a certain viscosity, so when the light-transfer powder is poured into the resin, the light-transfer powder will gather on the surface of the resin, and direct stirring will cause the light-transfer powder to agglomerate, and at the same time Part of the light-transforming powder located on the surface of the resin will splash into the air, causing certain economic losses while polluting the air. In addition, when the existing device performs upper mold operation, the inje...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the existing device when mixing the resin and the light-transforming powder, due to the viscosity of the resin, the light-transforming powder will accumulate on the surface of the resin layer after being poured into the resin, and the light-changing powder will appear when it is directly stirred. Agglomeration phenomenon, at the same time, part of the light-transforming powder on the surface of the resin will splash into the air, causing certain economic losses while polluting the air. In addition, when the existing device performs upper mold operation, the nozzle will be inserted into the mold and then injected Resin, when the injection head is pulled out, the resin content in the mold will be insufficient. In addition, when the existing device is sealed, the sealing tape will wrinkle, resulting in uneven resin at the mold opening. , there will be a gathering phenomenon at the end of the sealing tape, which will reduce the stability and cause the shortcoming of the sealing tape to detach. The technical problem of the present invention is to provide an expansion-type optical telescope lens upper mold device
