Abstract
An optical element manufacturing device includes a mold set including: a first shaping mold and a second shaping mold facing each other with a shaping-target material between the first and second shaping molds, and a sleeve located around the first and second shaping molds; and a plurality of stages on which the mold set is conveyed and which heat, press or cool the shaping-target material. The sleeve is conveyed to the stages in such a manner that a conveyance-direction front side of the mold set in an arrangement direction of the plurality of stages has a heat insulation portion with a heat insulation property that is higher than that on a conveyance-direction rear side of the mold set in order to reduce a temperature distribution in the shaping-target material.
Claims12
An optical element manufacturing device comprising:
- a mold set including a first shaping mold and a second shaping mold facing each other with a shaping-target material between the first and second shaping molds, and a sleeve located around the first and second shaping molds;
- and
- a plurality of stages on which the mold set is conveyed and which heat, press or cool the shaping-target material, wherein
- the sleeve is conveyed to the stages in such a manner that a conveyance-direction front side of the mold set in an arrangement direction of the plurality of stages has a heat insulation portion with a heat insulation property that is higher than that on a conveyance-direction rear side of the mold set in order to reduce a temperature distribution in the shaping-target material.
An optical element manufacturing device comprising:
- a mold set including a first shaping mold and a second shaping mold facing each other with a shaping-target material between the first and second shaping molds, and a sleeve located around the first and second shaping molds;
- and
- a plurality of stages on which the mold set is conveyed and which heat, press or cool the shaping-target material, wherein
- the sleeve is conveyed to the stages in such a manner that at least one of horizontal directions, which are orthogonal to arrangement directions of the plurality of stages, has a heat insulation portion with a heat insulation property that is higher than that on a conveyance-direction rear side of the mold set in the arrangement directions in order to reduce a temperature distribution in the shaping-target material.
An optical element manufacturing device comprising:
- a mold set including a first shaping mold and a second shaping mold facing each other with a shaping-target material between the first and second shaping molds, and a sleeve located around the first and second shaping molds;
- and
- a shaping chamber in which a gas intake is formed through which a substitution gas flows into the shaping chamber, wherein
- the sleeve is conveyed to the stages in such a manner that a side of the gas intake in circumferential directions of the sleeve has a heat insulation portion with a heat insulation property that is higher than a side of at least part of other portions in order to reduce a temperature distribution in the shaping-target material.
