The invention relates to the manufacture of an optical component and an optical component, and more particularly to a combined lens and a mold apparatus and a manufacturing method thereof for manufacturing the combined lens, and a method of using the combined lens Lens module. [Prior Art] At present, the lens is mostly produced by a multi-cavity and injection molding method. When the lens module is assembled, a plurality of lenses, a lens barrel, a spacer, an image sensor, etc. are placed on the assembly tray, and then They are assembled together in a certain order. This type of assembly requires a high degree of precision. However, the accuracy of the assembly is not easy to control, especially when the lens module uses a plurality of lenses, the alignment of the center of the lens and the coincidence of the optical axes is a critical step. At the same time, a mold can only produce one type of lens at a time to increase the manufacturing cost of the lens module. SUMMARY OF THE INVENTION There is a need for a combination lens to eliminate the misalignment that may occur during assembly. At the same time, it is also necessary to provide a mold for producing the combined lens to reduce the manufacturing cost of the mold. A combined lens comprising a first lens and a second lens, the first lens and the second lens respectively comprising an optical zone and a solid region surrounding the optical zone, the combined lens being integrally formed, the first lens The optical zone is opposite to the optical zone of the second lens of the 6201003167 and has a gap therebetween, and the fixed area of the first lens is connected to the fixed area of the second lens. A mold apparatus for manufacturing a combined lens, comprising: a first mold core and a second mold core, wherein the first mold core and the second mold core form a first semi-closed cavity, and a first module is disposed through the mold The first half closes the cavity to form a closed molding cavity for forming a combined lens. A method of manufacturing a combined lens, comprising the steps of: providing a first mold core and a second mold core; and combining the first mold core and the second mold core to form a first mold core and the second mold core The first half of the cavity is closed; at least one mold core is selected according to the design, and the at least one mold core is installed in the first module; and the distance between the at least one mold core and the first mold core and the second mold core is adjusted; Providing the first module in the first semi-closed cavity to seal the first semi-closed cavity to form a molding cavity; injecting a lens molding material into the molding cavity; cooling; extracting the first module to remove the The first mold core and the second mold: a combined lens. 4: A method for manufacturing a combined lens, comprising the steps of: providing a first-, a core and a second mold; and clamping the first mold and the second mold, between the second and the second mold Forming a plurality of closed cavities; forming a plurality of modules ^ (4), (4) the (four) and a half (four) cavities are sealed to form a molding cavity, and any module of the δ 稷 number module includes at least a die, the at least one die And adjusting the distance between the first mold core and the second mold core; injecting the lens molding material into the second cavity; cooling, extracting the plurality of modules, removing the crucible and the second mold core, and obtaining the combined lens . Compared with the prior art, the combined lens provided by the present invention comprises two mirrors 7 201003167, the non-optical portions of the two lenses being connected, so that it is not necessary to align the centers of the two lenses. The mold provided by the present invention can produce a combined lens comprising two lenses, so that it is no longer necessary to design two molds to manufacture two lenses, which greatly reduces the cost of manufacturing the mold. [Embodiment] Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings. Referring to FIG. 1, a combination lens 10 according to a first embodiment of the present invention includes a first lens 102 and a second lens 104 opposite to the first lens 102. Wherein, the first lens 102 has a first optical zone 1021 and a first fixed zone 1022, and the second lens 104 has a second optical zone 1041 and a second fixed zone 1042. The first lens 102 and the second lens 104 are integrally connected by the first fixing region 1022 and the second fixing region 1042, and the first optical zone 1021 and the second optical zone 1041 are opposed to each other. Referring to Fig. 2, the combined lens 20 of the second embodiment of the present invention is substantially identical to the combined lens 10, except that the combined lens 20 includes three lenses 201, 202 and 203. The three lenses are integrally formed, and the optical zones of adjacent lenses are opposite, and the fixed zones of adjacent lenses are connected. Referring to Figure 3, a mold 30 according to a third embodiment of the present invention is used to produce a composite lens 10. The mold 30 includes a first mold core 301, a second mold core 302, and a first mold module 303. The first mold core 301 has a first molding surface 31 and a side surface 2011, and the side surface 2011 is provided with a U-shaped opening at the edge of the first mold core 301; 8 201003167 The outer mold core 302 has a second molding surface 32 and a side surface 2〇21, the side surface 2〇21 is provided at the edge of the second mold core 302 with a U-shaped opening opposite to the opening direction of the U-shaped opening of the first mold core 3〇1. The first module 303 has a mold core 38 and an extension 35 perpendicular to the mold core. The mold core 38 has a third molding surface 33 and a fourth molding surface 34 opposed to the third molding surface 33. The shape of the molding surface 33 and the fourth molding surface 34 is determined according to the optical design, and the distance between the second molding surface 33 and the fourth molding surface 34 is the distance between the two lenses after molding. If the size of the U-shaped opening of the first mold core 3〇1 and the second mold core is constant, the size and shape of the extension portion 35 are unchanged. 3〇2 Read the picture^Fig. 5 and Fig. 6 'The first mold core and the second mold core: the U-shaped groove of the two mold cores are formed - the semi-closed cavity of the end opening is deleted. The first module 303 is bored in the semi-closed cavity 3〇4. >: The extension 4 35 matches the opening of the semi-closed cavity 3〇4. When the first module = the second molding surface 33 and the fourth molding surface 34 reach the predetermined position, the surface of the epitaxial # 35 is just flush with the side surface (10) of the side edge 302 of the first mold core, and thus the semi-closed cavity The closed gate of the i-shaped module, for example, the second mold, and the first module 303 form a closed cavity 6〇. The lens molding material is injected into the molding cavity 60 through the flow path (not shown) of the first mold core 301 or the first mold core 301 or the first core 301, and is cooled; the first mold core 301 and the second portion are removed. The mold core extracts the first module 303 302 to obtain a combined lens ι. 201003167 First: Γ 'The semi-closed cavity 304 can also be formed in other ways. For example, f 301 has a half of the two-sided opening as shown in this embodiment. 1: 1: The side of the two-die 302 is not open. The mouth, when the two molds σ杈 will also form a half closed cavity. In the seventh embodiment, the mold 4G provided by the fourth embodiment of the present invention is substantially the same as the mold 30 of the third ==. The difference is that the first module:: ^Laren 48 and 49, and one and two molds The vertical outer extension of the female coix seed has two opposing molding faces. The first mold core, the second mold core = 〇 2, the mold core 48 and the mold core 49 cooperate to form a combined lens 2 〇. ^Using the combined mold 3G to manufacture the combined mirror material, firstly, according to the optical design, the first module 403 can be installed with a complex mode according to actual needs.
