Field of the Invention The present invention relates to a molding technique, and more particularly to a lens molding die and a molding method thereof. [Prior Art] Conventional lens lens forming molds include a male mold, a female mold, a mold core, and a runner system. There is only a small amount of holes in the master that can be loaded into the mold, and there is generally only one mold cavity on the mold. The flow channel system includes an injection flow channel, a main flow channel, and a bypass channel. By injecting a plastic liquid from a male mold, the plastic liquid flows through the injection flow path, the main flow path, and the split flow path, and then is cooled into a lens in the mold cavity of the mold. The above method can only form a small number of lenses at a time, which greatly limits the lens yield. In addition, the plastics molded in the runner system are treated as waste, causing great waste. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a lens forming mold and a molding method thereof which are high in yield and capable of saving materials. Mirror - a kind of lens into a beauty, which includes the job of the public Shu Lai. The male model is provided with an injection (four) and a flow passage extending from the miscellaneous orifice. The male mold has at least two upper grooves and at least two lower grooves opposite to the mother. The male mold and the mother mold are provided with a main passage connecting the upper and lower grooves and the charm flow passage. The upper concave body has a plurality of upper cavities, and the concave surface of the lower concave groove is formed with a plurality of lower cavities, and the die-shaped shirt groove is broken and used for forming 6 200948584 - the dough piece is formed into a wealth method, and the financial method includes the steps of the above-mentioned H a lens forming mold; molding the male mold with the mold; injecting the material to be molded, and molding the material to be molded into a job and obtaining the array; cutting the two directions in two directions perpendicular to each other Lens array. Compared with the prior art, the lens forming mold provided by the present invention simultaneously sets a plurality of molding cavities on the male mold and the female mold, and does not need to make a plurality of single linings - the secondary molding of the plurality of lenses improves the production of the lens while reducing The cost. Moreover, it is not necessary to provide a branching passage ‘only need to inject the flow passage and the main flow passage, and the waste formation of the injection molded product is reduced. [Embodiment] Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings. Please refer to ® 1, which is a lens forming mold 1 for providing a molding material into a shape sheet, which may be plastic or glass, in the present embodiment, 雠. The lens molding mold! (10) includes a reciprocal male mold ι and a female mold 20. Referring to Figures 1 through 3, the male mold 1 includes an injection port u and an injection flow path 12 extending from the injection port 11. The upper mold 1 has an upper parting surface 13 , and the upper parting surface 13 is provided with at least two upper grooves 14 and a concave surface 3 communicating with the upper grooves 14 and the main flow path 30 of the injection flow path 12 . 〇1. The at least two upper grooves 14 are symmetrically disposed with respect to the injection flow path 12, and the upper surface of the upper groove 14 is formed with a plurality of upper cavities 15 having a recessed shape. In the present embodiment, the number of the upper grooves 14 is two, and the number of the upper cavities 15 is 25, which forms an array of -5*5. In this embodiment, the upper groove 14 can be integrally formed with the male mold 10, and the upper mold core can also be provided with at least two upper mold cores, and the height of the upper mold core is smaller than the height of the male mold 10, thereby The upper groove 14 is formed between the end faces of the mold face 13 7 200948584. The male mold buckle further includes a first pair of eight-mode ίο^ pairs of cold egg paths 17 for the cooling liquid shaft for fine cooling of the mold G during the injection molding process, which can be a cooling oil cooling oil. The flail includes at least two recesses 21 opposite the upper recess 14 , one by one Γ and the main passage 30 of the boring 12 are concave (four), - a: gamma:: the die face 22 extends and The cold well 23 corresponding to the injection flow path 12 is cooled to the cooling circuit 24. In the present embodiment, similar to the upper recess 14, the female cymbal 2 曰 0 can be integrally formed with the female mold 20, which can also provide a lower recess 21 than the county by providing a lower height. The lower neck 21 is formed with a complex surface. The cavity 15 is corresponding to the cavity 15'. The lower cavity 25 and the upper cavity 15 are combined with the concave and convex surface of the lens. The cold well 23 is the end of the injection flow passage 12, and the cold material of the molded product is affected by the temporary cold material to prevent the cold material from entering the lower groove 21, and the column can be a rectangular parallelepiped. Body or right angle triangular prism. The next: trough phase cold well 23 _ set. The second cold phase path % is used for cooling liquid flow or = the master mold 2 is cooled during molding. The coolant may be cooling water. When the male mold 10 is clamped with the master mold 20, the upper common Forming the complete molding is performed on the molding lens, and the upper concave surface and the lower concave groove 3〇2 are formed in a strip-connecting manner to the main channel of the complete molding bribe. In the process of injection into the ancient k-process, the mold 10 is closed with the mother mold 2, and the hot-melt fluid-like plastic is better than the high temperature and the same as the lower one. (4) Injection Π u injection, through the injection of the flow channel 12 after the mainstream The passage 30^ flows to the complete molding cavity, and finally to the complete molding cavity_cooling molding. At the same time, the coolant in the second cooling circuit 17 and the second cooling circuit % cools the male mold and the female mold by 20 minutes. The male mold 1G rogue W is divided into molds, and the molded product of 8 200948584 can be injected. The lens is taken out and the formed lens is cut in two directions perpendicular to each other to obtain a plurality of lenses at the same time, and waste is formed only in the injection flow path 12 and the main flow channel 3 and the cold well 23 in the process. 4. The lens forming method of the present invention comprises the following steps: Step S100: providing a lens forming die force. Step S200: clamping the male die 10 and the female die 2 when the male die 1 and the female die are When the mold is closed, the upper groove w and the lower groove form a complete molding cavity for molding the lens 0 ❹ Ο step S300. The material to be molded is injected, and the material to be molded is cooled and formed into the complete molding cavity. In the embodiment of the lens, in the embodiment of the present invention, the hot-melt fluid-like plastic is injected into the π U in a warm and high-pressure environment, and after passing through the flow channel 12, the entire surface is formed through the social flow channel 23, and finally in the complete (four) Cooling molding. The material to be molded is in the mirror After the molding die is cooled, an injection molded product is formed, and the injection molded product is included in the injection flow path 12, the main flow path 3〇, and a portion of the complete molding cavity. Step S400: mold opening and obtaining the lens array. The injection molded article is taken out and the waste material is removed to leave the lens array. In the present embodiment, the molded portion in the injection flow path 12 and the main flow path 30 is treated as waste. Step S500: Two perpendicular to each other The lens array is cut in the direction, and the lens under (4) is formed into small squares, which are directly used after being subjected to the mineral film. The lens provided by the present invention is used to form the plurality of molding cavities simultaneously in the male mold 1 and the female mold. 2〇, you can shape multiple lenses at one time without using multiple single-hole molds, which reduces the cost of the lens and reduces the cost. Moreover, you only need to inject the runner 12 and the main channel 30 without reducing the flow. The formation of scraps for injection moldings. 9 200948584 & «Only" "The above-mentioned series of purchases of the patent application scope of this case.
