Fixed glass moulded shaper for simplifying core-takeout operation

Abstract

A fixed glass mould forming device with simplified core-out operation is prepared by heating and pressurizing for glass nitre materials to form into a glass lens with a lower mould unit, limiting cylinder and a upper mould unit, which contain a lower mould and upper mould bases and mould cores set in lower and upper moulds, placing limiting cylinder on one side of the lower mould core. The glass nitre material is arranged in internal limiting cylinder to close upper and lower mould units. It saves core made time and shorten procedure.

Description

technical field [0001] The invention relates to a forming device, in particular to a fixed glass molding device which can simplify the core-taking operation. Background technique [0002] As shown in FIG. 1 and FIG. 2 , there is an existing mold for forming optical glass lenses, which includes a lower mold unit 1 and an upper mold unit 2 that can be attached to or separated from the lower mold unit 1 . The lower mold unit 1 has a lower mold base 101 and a lower mold core 102 installed in the lower mold base 101, and the upper mold unit 2 also has an upper mold base 201 and a lower mold base installed in the upper mold base 201. The upper mold Jen 202. After a glass nitrate material 3 is placed on the lower mold core 102, the upper mold unit 2 can move down during the high-temperature molding process and come into contact with the lower mold unit 1, and the glass nitrate material 3 is press-formed It is a glass lens 4. [0003] But as shown in Fig. 1 imaginary line and Fig...

Problems solved by technology

However, since the glass lens 4 or the fleshy lens 5 is formed, the peripheral surface 401 of the glass lens 4 (or the peripheral surface of the fleshy lens 5) is not constrained by a specific structure. Therefore, the glass lens 4 or the fleshy lens 5 will not form a configuration with a completely uniform outer diameter. When the operator performs the coring operation, it often takes a considerable amount of time to find the core point, especially the cost of the fleshy lens 5. The time is longer, because the outer diameter of the glass lens 4 or partial flesh lens 5 is not uniform, and the operator operates the core mold 6 by experience and feeling, which often causes the found core point to deviate The actual optical axis position of the finished lens 4' leads to the problem of bad centering. In addition, because the outer peripheral surface 401 of the glass lens 4 or the outer peripheral surface of the partial flesh lens 5 is not constrained during molding, the glass The outer diameter of the lens 4 or the fleshy lens 5 will be much larger than the customer-supplied outer diameter D of the finished lens 4', and it takes a very long turning time to turn it to meet the specification
