Abstract
The utility model provides a kind of molding die of chalcogenide glass aspherical lens, includes upper cores and lower mode, and upper cores and lower mode enclose the forming cavity of an aspherical lens between the two when merging；Upper cores and lower mode are respectively arranged in the putting hole of cope match plate and the putting hole of mould board, and cope match plate and mould board are provided with guide hole, and guide post is inserted in guide hole, and cope match plate and mould board mold along guide post or divide mould.In the utility model, chalcogenide glass aspherical lens are produced using molding die, without relying on high-precision process equipment, process time is reduced, improves yields, and then reduce production cost；Cope match plate and mould board are oriented to using guide post, gas can directly be discharged between cope match plate and mould board, and exhaust efficiency is high, and gas is not detained in forming cavity, avoids interiors of products from bubble occur, further increase yields.
Description
Technical field
The utility model relates to optical element mould pressing technology field more particularly to a kind of moulds of chalcogenide glass aspherical lens
Compression mould.
Background technique
The production method of traditional chalcogenide glass aspherical lens is to be obtained using Ultra-precision Turning equipment turning.However it passes
The production method of system is very high to the required precision of process equipment, and process time is longer, and yields is low, this all considerably increases production
Cost.
105036527 A of patent CN discloses a kind of chalcogenide glass molding die and mould pressing method, utilizes mould pressing process
The machine-shaping to chalcogenide glass is realized, process time is reduced, improves yields.However, utilizing sleeve in the patent
On gas vent be exhausted, since the exhaust efficiency of gas vent is lower, in mold process mould inside be easy entrapped air volume, lead
It causes interiors of products to be easy to appear bubble, influences product use.
Utility model content
The technical problems to be solved in the utility model is that it is non-to provide a kind of chalcogenide glass according to above-mentioned the deficiencies in the prior art
The molding die of spheric glass can not only reduce production cost, interiors of products can also be avoided bubble occur.
The technical solution of the utility model is as follows:
A kind of molding die of chalcogenide glass aspherical lens includes upper cores and lower mode, and the upper cores are under
Mode encloses the forming cavity of an aspherical lens between the two when merging；The upper cores and lower mode are respectively arranged in mo(u)ld top half
In the putting hole of plate and the putting hole of mould board, the cope match plate and mould board are provided with guide hole, and guide post is inserted in described lead
In hole, the cope match plate and mould board mold along the guide post or divide mould.
Further, the cope match plate upper surface is connected with upper mounted plate, and the mould board lower surface is connected with lower fixation
Plate.
Further, adjustment gasket is provided between the upper cores and upper mounted plate.
Further, adjustment gasket is provided between the lower mode and bottom plate.
Further, fixed plate and bottom plate are provided with nitrogen charging stomata, and the nitrogen charging stomata is put with described
Set hole connection.
Further, fixed plate and bottom plate are respectively provided with temperature-sensitive string holes.
Compared with prior art, the utility model has the following beneficial effects: (1) produces chalcogenide glass using molding die
Aspherical lens reduce process time, improve yields, and then reduce production without relying on high-precision process equipment
Cost；(2) cope match plate and mould board being oriented to using guide post, gas can directly be discharged between cope match plate and mould board,
Exhaust efficiency is high, and gas is not detained in forming cavity, avoids interiors of products from bubble occur, further increase yields；(3) it adjusts
Whole gasket can be replaced according to production requirement, and a set of molding die is allow to assemble the upper cores and lower die of plurality of specifications
Benevolence reduces the cost of production equipment.
