DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to an apparatus for molding a lens, and more particularly to a mold set which can guide a core to a core. [Prior Art] As shown in Fig. 1, a mold set of a moldable lens is provided, which comprises a first mold unit 1, and a second mold unit 2 disposed opposite to the first mold unit 1. The first and second mold units 丨, 2 each have a template 101, 201, and stencils 1, 2, 202 disposed on one side of the stencils 1, 〇1, 2〇1, and one of the stencils 102, The internal model of 202 is 1〇3,203. The stencils 102, 202 each have a seat hole 1 〇 5, 205 for the modulating position 1 〇 3, 2 〇 3, and the dies 103, 203 each have a bearing surface 1 〇 6, 2 The crucible 6 and a shaping surface 1〇7, 207 recessed on the bearing surfaces 106, 206. The stencils 102, 202 are oppositely provided with a clamping face 1 〇 8, 208. When the first and second mold units 1 and 2 are joined to each other, a core thickness can be formed between the center points of one of the axes of the molding faces 1 and 7, 207 of the mold cores 103 and 203. . Although the above-mentioned mold set can achieve the purpose of molding the lens, the accuracy of the lens is getting higher and higher, and the machining precision has reached the limit. The traditional mechanical manufacturing and assembly methods obviously cannot meet the precision requirements of the lens. As shown in FIG. 2, there is a prior art precision optical grade injection molding machine for mounting and positioning of a mold set, which comprises a fixed mold base 3, a movable mold base 4 and a movable mold base 4 relative to the fixed mold base. 3 The toggle mode 5 of the switch mode and the mode-locking is generated, and the connection structure of the toggle unit 5 is caused by the manufacturing and assembly 1258416, and the wear and tear causes an error, which causes the movable (four) 4 recording drive to be skewed on the moving path. Therefore, the mold set is also relatively skewed and offset. Then the formed lens will have the problem that the optical axis shown in Fig. 3 is not on the same line (not on the core), and the mirror tilt as shown in Fig. 4 (the light vehicles intersect at a distance)

The yield of the lens can be improved. 2. In the closed state, by the elastic holding action of the elastic members 13, the % of the memory ring connected to the buckle 27 can be axially positioned, and the mold cores 12, 22 can also be held. On the inner side surface (4), it is ensured that the core thickness value between the molded faces 124, 224 of the mold cores 12, 22 does not change. Secondly, in the closed mode state and the memory ring member 3 () is simultaneously fitted on the mold cores 22, 22, the radial limit of the mold core & 22 is utilized by the limit ring member 16, It can be avoided that when the memory ring member 3 is heated and tightened to the mold cores 12, 22, the large diameter end portions 121, 221 of the mold cores 12, 22 are free from the inner side surfaces 142, 242, causing wear. . 4. In the mold opening state, by using the cooling of the memory ring member 3 to make the ring member 30 expand, the inner ring surface 31 and the peripheral edge of the formed lens can be laterally separated. In this way, the surface change due to the lens ejection can be reduced, the defect rate can be reduced, and since the lens periphery has generated 12 5^416 lateral release, the lens has no radial constraint from the top surface 31. Force, so the top cup does not have to wait for the lens to completely eject the lens without affecting it. The brother-face type can shorten the cycle time of lens forming. 5. Using the memory ring member 3G at the same time, the mold core 12, 2 is paired with the core, there is no problem of cumulative tolerance, and a "machine" excludes all the gaps of the design of the mold design σ and juice, and the resulting gap Consideration. In the above embodiment of the present invention, the first mold unit 10, 20 is an injection mold. If the lens material surface; ^ and the use of the secondary enamel, it is to put a true material pre-shaped body on the second early 70 molds, and then the first mold Cuiyuan relative to the first eight early 7G The purpose of the combination is to achieve the purpose of molding. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent change made by the application of the present invention and the scope of the invention. And modifications are still within the scope of the invention patent.
