The utility model relates to mould kernel field, particularly relates to a kind of cavities in the manufacture of optical lenses

Technical background: existing optical lens is more of the molding, but mold molding, the mold will there is a large number of air, and the presence of air will affect the optical lens forming, increase the rate of optical lens of the defective goods, reduce the production of optical lenses quality and market competitiveness. Though some of the existing optical lens production mold also has the function of exhaust, but the structure is complex, exhaust effect is still not ideal. So you need to design a simple structure, easy to exhaust the optical lens mold to solve the above problems. The utility model in the mold cavities, by setting on the mould kernel exhaust structure to solve the above problems, and the exhaust of simple structure, easy to implement, this too low. Technical implementation elements: the utility model proposes the cavities in the manufacture of optical lenses, solves the existing optical lens production mold exhaust structure complex and the defects of exhaust effect is not ideal. Of the technical scheme of the utility model is that: a mould kernel used in the manufacture of optical lenses, including the cavities and the lower mold, mold cavities including on column and described on the die, the die head connection on the column of the front end of upper die, die on the front end for arc convex, described the cavities including lower die column and lower die, the die head connection in die column on the front end of the die head front for cooperate with arc convex concave arc, the side of the column of upper die and lower die column are set up with annular exhaust grooves, column of upper die and lower die column annular exhaust grooves on their connection with to the end of a column of upper die and lower die column exhaust duct. Further, described in the column of upper die and lower die column are described for the circular column. Described further, described in the column of upper die and lower die the end of the column are set up several fixed bolt hole. Described further, described in the column of upper die and lower die column of the front end is greater than the end. Beneficial effects of this utility model: the utility model in the side of the column of upper die and lower die sets with annular exhaust grooves and exhaust, simple structure, low adult, but good exhaust effect; In addition, the front end of the column of upper die and lower die column set to greater than the end, and more help to the exhaust, exhaust effect is good. Illustrated instructions in order to more clearly this utility model example existing technology or the technical proposal, the following described for example or existing technology in the appended drawings of the need to use introduce simply, clearly, described below the appended drawings is just some of the utility model example, for the field common technical personnel, on the premise of not giving creative labor, can also according to the appended drawings for other appended drawings. Figure 1 for the mould kernel structure schematic diagram; Figure 2 for the mould kernel structure diagram. Concrete implementation way of the following will be combined with the appended drawings of the utility model implementation, this utility model implementation case clearly and completely describe the technical scheme of obviously, described the implementation of the case is just a part of the utility model implementation example, rather than the implementation of all cases. Based on the example of the utility model, the field common technical personnel under the premise that did not make a creative labor for all other cases, all fall within the scope of protection of the utility model. Refer to figure 1 2, a mould kernel used in the manufacture of optical lenses, including cavities mould kernel under 1 and 2, described mold cavities 1 including on column 11 and 12 on the die and the die head 12 connected, in the front of the upper die column 11, 12 front-end for arc convex on the die and the cavities 2 including lower die die under 21 and 22, 22 connection next die die head column under 21 on the front end of the die head and front end to cooperate with arc convex arc concave, column 11 of upper die and lower die column 21 are circular column, column 11 of upper die and lower die 21 the front end of the column is greater than end, column 11 of upper die and lower die on the side of the column 21 are set in annular exhaust grooves, annular exhaust groove can be a circle, also can be more circle, according to the need to set up, 21 column 11 of upper die and lower die column annular exhaust grooves on their connections to the upper die column 11 and 21 tail exhaust duct lower die column 4. Upper die and lower die column column 11 in which there are several fixed bolt hole that the end of the 21 5, fixed bolt hole on the 5 used to mould kernel cavities under 1 and 2 on the mould. The utility model has simple structure, low adult, but good exhaust effect. Described above only for the better implementation of the utility model case, is not used to limit the utility model, all within the spirits and principles of the utility model, for any modification, equivalent replacement, improvement, etc. , shall be included within the scope of protection of the utility model. Technical features: 1. A mould kernel used in the manufacture of optical lens, whose character is: including the cavities and the lower die, mould cavities including on column and described on the die, the die head connection on the column of the front end of upper die, die on the front end for arc convex, described the cavities including lower die column and lower die, the die head connection in die column on the front end of the die head front for cooperate with arc convex concave arc, the side of the column of upper die and lower die column are set up with annular exhaust grooves, column of upper die and lower die column annular exhaust grooves on their connection with to the end of a column of upper die and lower die column exhaust duct. 2. As right request 1 stated the cavities in the manufacture of optical lenses, whose character is: described in the column of upper die and lower die column are described for the circular column. 3. As right request 1 stated the cavities in the manufacture of optical lenses, whose character is: described in the column of upper die and lower die column described in which there are several fixed that the end of the bolt hole. 4. Claim 1 - Any mentioned in item 3 of cavities in the manufacture of optical lenses, whose character is: described in the column of upper die and lower die column described front end are greater than the end.
