Abstract
The utility model discloses a kind of mould producing contact lens material, comprise die ontology, described die ontology comprises upper cover and closed type cell body, and described upper cover covers on closed type cell body, described upper cover bottom surface is outer convex arch, is indent circular arc in closed type cell body; The utility model have employed sealed cell body, effectively reduces entering of the material such as impurity and air, substantially increases product qualified rate; Bracing frame is hollow structure, thermal source is directly contacted with bottom cell body, effectively avoids the factor that heat transfer is slow, improve efficiency; The contact lens material edge that the mould adopting the utility model to provide is produced is without seam, more smoothly mellow and full, contacts more comfortable, and save contact lenses raw material with eyeball, reduces production cost; The utility model simple structure, easy to use.
Description
Technical field
The utility model belongs to contact lenses and makes mould applications, particularly a kind of mould producing contact lens material.
Background technology
Contact lenses are used for correcting defects of vision or protect the eyeglass of eyes to be widely known as a kind of being worn on cornea.And the edge of materials that known contact lens molds is produced is seam, and this mould can produce the material had without seam edge." seam " refer to the line or boundary line that are formed by the lens materials of surplus.And this seam can contact with conjunctiva, rough surface can be caused, the uncomfortable sensation of eyeball.
Be still without the production of sewing up contact lens material and there is certain difficulty, comprise as how minimum geometrically left and right displacement and obtain without seam edge without the need to post-processing step.In addition, mould lobe in front and back does not mate and misplaces is produce the major obstacle without seam edge.Finally, before curing, unnecessary lens materials must be removed from eyeglass.
In prior art, supporting construction is compact-type, and thermal source needs to form structure by closely knit, then is delivered to cell body, waste resource, and operating efficiency is extremely low.
Therefore, a kind of mould without seam edge contact lenses is badly in need of to overcome above-mentioned defect.
Utility model content
The purpose of this utility model is to provide a kind of mould producing contact lens material, to solve the contact lenses seam produced in prior art, causes rough surface, wears and makes the uncomfortable problem of eyes.
For achieving the above object, the utility model is by the following technical solutions:
Produce a mould for contact lens material, comprise die ontology, described die ontology comprises upper cover and closed type cell body, and described upper cover covers on closed type cell body, and described upper cover bottom surface is outer convex arch, is indent circular arc in closed type cell body.
Further, the seam crossing between described upper cover and closed type cell body is full seal type.
Further, described outer convex arch and indent circular arc match.
Further, described die ontology lower end is provided with bracing frame.
Further, support frame as described above is hollow structure, and thermal source directly can contact with bottom closed type cell body.
The beneficial effects of the utility model: the utility model have employed sealed cell body, effectively reduce entering of the material such as impurity and air, substantially increase product qualified rate; Bracing frame is hollow structure, thermal source is directly contacted with bottom cell body, effectively avoids the factor that heat transfer is slow, improve efficiency; The contact lens material edge that the mould adopting the utility model to provide is produced is without seam, more smoothly mellow and full, contacts more comfortable, and save contact lenses raw material with eyeball, reduces production cost; The utility model simple structure, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1;
Wherein: 1-upper press cover, 2-closed type cell body, 3-bracing frame.
Detailed description of the invention
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the utility model further.
As shown in Figure 1, a kind of mould producing contact lens material, comprise die ontology, described die ontology comprises upper cover 1 and closed type cell body 2, and described upper cover 1 covers on closed type cell body 2, and described upper cover 1 bottom surface is outer convex arch, be indent circular arc in closed type cell body 2, sealed cell body 2, effectively reduces entering of the material such as impurity and air, substantially increases product qualified rate;
Seam crossing between described upper cover 1 and closed type cell body 2 is full seal type.
Described outer convex arch and indent circular arc match.
Described die ontology lower end is provided with bracing frame 3, space between bracing frame 3 and sealed cell body 2, thermal source can directly be contacted with sealed cell body 2, closed support is adopted, because closed supporting construction thermal source by closely knit supporting construction, then need contact with cell body in prior art, reduce thermal source utilization rate, and the bracing frame 3 in the utility model is hollow structure, effectively avoids the factor that heat transfer is slow, improve efficiency.
Support frame as described above 3 is hollow structure, and thermal source directly can contact with bottom closed type cell body 2.
A kind of mould producing contact lens material that the utility model proposes, saves contact lenses raw material, reduces production cost; And simple structure, easy to use.
Contact lens material is injected sealed cell body 2, cover upper cover 1, heat in an oven.The contact lens material that this mould utilizes the evagination circular arc that matches and interior concave arc to realize as cell body shape.
The utility model have employed sealed cell body, effectively reduces entering of the material such as impurity and air, substantially increases product qualified rate; Bracing frame is hollow structure, thermal source is directly contacted with bottom cell body, effectively avoids the factor that heat transfer is slow, improve efficiency; The contact lens material edge that the mould adopting the utility model to provide is produced is without seam, more smoothly mellow and full, contacts more comfortable, and save contact lenses raw material with eyeball, reduces production cost; The utility model simple structure, easy to use.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
