Abstract
The invention discloses a ceramic die for producing an optical lens. The ceramic die comprises a male die and a female die matched with the male die, a first groove is formed in the male die, a male die kernel is fixed in the first groove, a second groove is formed in the female die, a female die kernel is fixed in the second groove, a first forming groove and at least three lens feeding ports are formed in the male die kernel, each lens feeding port is communicated with the first forming groove, a second forming groove is formed in the female die kernel, and edge shape of the second forming groove is identical with that of the first forming groove. Compared with the prior art, the ceramic die has the advantages that four lens feeding ports are formed, molten lens raw materials can be injected into a forming cavity in four directions at the same time, and the raw materials in the forming cavity are distributed uniformly, so that quality and qualification rate of the optical lens are improved.
Description
Technical field
The present invention relates to a kind of ceramic die for the production of optical mirror slip.
Background technology
In the prior art, manufacture optical mirror slip and have two kinds of methods: a kind of is traditional polishing, optical mirror slip need to pass through long grinding, polishing and the moulding of clean operation ability, and the eyeglass poor quality of producing, and qualification rate is low. Another kind is mold injection method, carry out rapid batch with ceramic die and produce optical mirror slip, but, existing ceramic die is generally only provided with a charging aperture, inhomogeneous when Raw materials for lenses injection moulding, cause the intensity of optical mirror slip each several part inhomogeneous, reduce the quality of optical mirror slip, therefore, be necessary to provide a kind of new ceramic die to solve the problems referred to above.
Summary of the invention
The object of the present invention is to provide a kind of ceramic die for the production of optical mirror slip that can improve optical mirror slip quality and qualification rate.
To achieve these goals, the technical solution adopted in the present invention is as follows:
A kind of ceramic die for the production of optical mirror slip, the master mold that comprises male model and match with described male model, described male model is provided with the first groove, in described the first groove, be fixed with male die core, described master mold is provided with the second groove, in described the second groove, be fixed with mother module core, on described male die core, offer the first forming tank and at least three eyeglass charging apertures, described in each, eyeglass charging aperture is communicated with described the first forming tank, on described mother module core, offer the second forming tank, the edge shape of described the second forming tank is identical with the edge shape of described the first forming tank.
Preferably, in the time that described male model covers on described master mold, the coincident of the edge of described the second forming tank and described the first forming tank, between the inwall of the inwall of described the first forming tank and described the second forming tank, form molding cavity, the shape of described molding cavity is identical with the shape of optical mirror slip.
Preferably, described eyeglass charging aperture is provided with four.
Preferably, the distance between every adjacent two described eyeglass charging apertures equates.
Preferably, described male model inside is provided with feed pipe, and described feed pipe is communicated with eyeglass charging aperture described in each.
Compared with prior art, the present invention is for the production of the beneficial effect of the ceramic die of optical mirror slip: the present invention is provided with four eyeglass charging apertures, can divide four direction simultaneously toward the interior Raw materials for lenses that injects melting of molding cavity, make the feed distribution in molding cavity even, thereby improve quality and the qualification rate of optical mirror slip.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention for the production of ceramic die one embodiment of optical mirror slip;
Fig. 2 is the structural representation of the present invention for the production of another embodiment of ceramic die of optical mirror slip.
In figure, each mark is as follows: 1, male model; 101, male die core; 102, eyeglass charging aperture; 2, master mold; 201, mother module core; 3, molding cavity.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further described.
Consult shown in Fig. 1 to Fig. 2, the invention provides a kind of ceramic die for the production of optical mirror slip, the master mold 2 that comprises male model 1 and match with described male model 1, described male model 1 is provided with the first groove, in described the first groove, be fixed with male die core 101, described master mold 2 is provided with the second groove, in described the second groove, be fixed with mother module core 201, on described male die core 101, offer the first forming tank and at least three eyeglass charging apertures 102, described in each, eyeglass charging aperture 102 is communicated with described the first forming tank, on described mother module core 201, offer the second forming tank, the edge shape of described the second forming tank is identical with the edge shape of described the first forming tank.
In the time that described male model 1 covers on described master mold 2, the coincident of the edge of described the second forming tank and described the first forming tank, between the inwall of the inwall of described the first forming tank and described the second forming tank, form molding cavity 3, the shape of described molding cavity 3 is identical with the shape of optical mirror slip.
In the present embodiment, described eyeglass charging aperture 102 is provided with four. In the time of concrete application, the quantity of described eyeglass charging aperture 102 also can be adjusted according to actual conditions such as eyeglass sizes.
In the present invention, the distance between every adjacent two described eyeglass charging apertures 102 is equal, and this structural design can make the Raw materials for lenses of melting evenly inject in described molding cavity 3. Described male model 1 inside is provided with feed pipe, and described feed pipe is communicated with eyeglass charging aperture 102 described in each.
Operation principle of the present invention is: in the time that needs are produced optical mirror slip, male model 1 is covered on master mold 2, then toward the interior Raw materials for lenses that injects melting of feed pipe, Raw materials for lenses enters in molding cavity 3 through described eyeglass charging aperture 102, in cavity 3 to be formed, fill after Raw materials for lenses, stop injecting Raw materials for lenses, open male model 1 after cooling, take out optical mirror slip.
In sum, the present invention is provided with four eyeglass charging apertures 102, can divide four direction simultaneously toward the Raw materials for lenses of the interior injection melting of molding cavity 3, makes the feed distribution in molding cavity 3 even, thereby improves quality and the qualification rate of optical mirror slip.
Below schematically the present invention and embodiment thereof are described, this description does not have restricted, and shown in accompanying drawing is also one of embodiments of the present invention, and actual structure is not limited to this. So, if those of ordinary skill in the art is enlightened by it, in the situation that not departing from the invention aim, without the creationary frame mode similar to this technical scheme and the embodiment of designing, all should belong to protection scope of the present invention.
