Summary of the invention
For addressing the above problem, the invention provides a kind of lens mould, improve the machining accuracy of lens mould, exhaust performance is good, improves the yields of major diameter eyeglass finished product.
The technical solution used in the present invention is: a kind of lens mould, comprise upper bolster and die shoe, die shoe upper end is provided with lower eyeglass groove, upper bolster comprise sleeve member with by sleeve member nested submodule benevolence, nested unit inside is provided with the first locating hole, the second locating hole and the 3rd locating hole, submodule benevolence comprises the first locating dowel, the second locating dowel and the 3rd locating dowel, the first locating dowel, the second locating dowel and the 3rd locating dowel are one-body molded, the first locating dowel, corresponding fit the first locating hole of the second locating dowel and the 3rd locating dowel, the second locating hole and the 3rd locating hole, the first locating dowel front end is provided with film trap on show.
In technique scheme, the first locating dowel is column structure, the first locating hole is the cylindrical hole structure corresponding with the first locating dowel, the second locating dowel is polygon column structure, the second locating hole is the polygon cylinder pore structure corresponding with the second locating dowel, the 3rd locating dowel is column structure, and the 3rd locating hole is the cylindrical hole structure corresponding with the 3rd locating dowel.
In technique scheme, the second locating hole is between the first locating hole and the 3rd locating hole, and the second locating dowel is between the first locating dowel and the 3rd locating dowel.
In technique scheme, the first locating dowel diameter and the first locating hole diameter are greater than lens optical face.
In technique scheme, during to sleeve member roughing, on the first locating hole, with screw, sleeve member is oppositely fixed on tool, sleeve member bottom is shaped.
In technique scheme, the 3rd locating hole shapes by jig grinder.
The invention has the beneficial effects as follows: a kind of lens mould of above-mentioned structure, the cooperation of the first locating hole and the first locating dowel is for exhaust, and exhaust performance is good, improves the yields of major diameter eyeglass finished product; The cooperation of the second locating hole and the second locating dowel can be located preferably, and the flexibility of transposing direction, can regulate the center of circle quadrant of lens mould, makes upper bolster and the die shoe center of circle more approaching, guarantees machining accuracy; The 3rd locating hole is processed by jig grinder, can guarantee that concentricity, out of roundness and perpendicularity are in 0.001MM, improves the machining accuracy of lens mould.
Accompanying drawing explanation
Fig. 1 is whole exploded view of the present invention;
Fig. 2 is global sections figure of the present invention.
In figure, 1, upper bolster; 11, sleeve member; 111, the first locating hole; 112, the second locating hole; 113, the 3rd locating hole; 12, submodule benevolence; 121, the first locating dowel; 122, the second locating dowel; 123, the 3rd locating dowel; 2, die shoe; 3, film trap on show; 4, lower eyeglass groove.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
Fig. 1 and Fig. 2 have schematically shown a kind of lens mould according to one embodiment of the present invention.
This kind of lens mould, comprises upper bolster 1 and die shoe 2.Die shoe 2 upper ends are provided with lower eyeglass groove 4.Upper bolster 1 comprise sleeve member 11 with by sleeve member 11 nested submodule benevolence 12.
Nested unit inside is provided with the first locating hole 111, the second locating hole 112 and the 3rd locating hole 113.Submodule benevolence 12 comprises that the first locating dowel 121, the second locating dowel 122 and the 3rd locating dowel 123, the first locating dowels 121, the second locating dowel 122 and the 3rd locating dowel 123 are one-body molded.The first locating dowel 121 is column structure, the first locating hole 111 is the cylindrical hole structure corresponding with the first locating dowel 121, the second locating dowel 122 is regular hexagon column structure, the second locating hole 112 is the polygon cylinder pore structure corresponding with the second locating dowel 122, the 3rd locating dowel 123 is column structure, and the 3rd locating hole 113 is the cylindrical hole structure corresponding with the 3rd locating dowel 123.Corresponding fit the first locating hole 111 of the first locating dowel 121, the second locating dowel 122 and the 3rd locating dowel 123, the second locating hole 112 and the 3rd locating hole 113.The first locating dowel 121 front ends are provided with film trap 3 on show.
During to sleeve member 11 roughing, on the first locating hole 111, with screw, sleeve member 11 is oppositely fixed on tool, sleeve member 11 bottoms are processed, process like this sleeve member 11 and there will not be horn mouth.
The 3rd locating hole 113 is processed by jig grinder, can guarantee that concentricity, out of roundness and perpendicularity are in 0.001MM.
When use is of the present invention, due to mismachining tolerance, film trap 3 on show and lower eyeglass groove 4 there will be bias, by measuring, can know place, center of circle quadrant, and by rotation the second locating dowel 122, make upper bolster 1 center of circle and die shoe 2 centers of circle in same quadrant, thereby guarantee the concentricity of upper bolster 1 and die shoe 2, further improve the optical property of product.And can be by regulating the height of submodule benevolence 12, the thickness of adjustable mirror sheet, is convenient to produce.
Above embodiment is merely illustrative and not limiting to the invention, and the equivalence of doing according to the method described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
