[0002] At present, with the development of science and technology, optical lenses have been widely used in technical fields such as digital cameras, mobile phones, projectors, and cameras. Optical lenses need to ensure high purity, transparency, uniformity, etc. during the production process. The industry uses various methods to manufacture optical lenses to meet the market demand for optical lenses of different specifications. At the same time, in order to reduce costs and improve efficiency, batch production is carried out to meet the demand for optical lenses.

[0003] Generally speaking, the coating process is one of the important steps in the subsequent processing. Coating refers to the use of physical or chemical methods to deposit a single or multi-layer thin film on the surface of an optical component, and utilizes the interference effect of incident, reflected and transmitted light at the thin film interface to achieve focusing, collimation, filtering, reflection and refraction effects.

[0004] During the coating process, a coating plate is generally used to fix the optical lens, thereby facilitating the coating work. Figure 1 A conventional mold assembly for manufacturing a coated plate is shown. Figure 2 for Figure 1 The coating plate manufactured by the mold assembly includes a structure for forming a lens placement hole 11. The coating plate produced by the mold does not have the function of drainage and cannot meet the actual needs. Therefore, it is necessary to design a mold to produce a Figure 3-4 The coating plate 10 shown has a drainage channel. The coating plate 10 is provided with a lens placement hole 11 for placing an optical lens, as well as a positioning hole 15 and a positioning post 16 for positioning the coating plate. Locking holes 12 and fixing posts 13 are then used to secure the two stacked coating plates 10 together for coating. Furthermore, the coating plate 10 also has a drainage channel, requiring a groove 14 to be provided on the coating plate 10, communicating with the lens placement hole 11, for drainage.

[0032] The embodiment of the present utility model provides a forming die assembly for a drainage coating plate, such as Figure 3-5Shown, including:

[0033] The mold A plate 100 is provided with a first forming seat 110 for forming the fixing column 13 and a second forming seat 120 for forming the positioning hole 15;

[0034] The mold B plate 200, the mold A plate 100 and the mold B plate 200 enclose a coating plate molding cavity 300. The mold B plate 200 is provided with a first molding portion 210 for molding the lens placement hole 11, a second molding portion 220 for molding the groove 14, a third molding portion 230 for molding the positioning hole 15 in cooperation with the second molding seat 120, and a fourth molding portion 240 for molding the positioning column 16.

[0035] The inserting pin 400 is fixed in the mold A plate 100 and is used to form the locking hole 12.

[0036] Two molding seats are provided on the mold A plate 100. The first molding seat 110 is used to mold the fixing column 13, and the second molding seat 120 is used to mold the positioning hole 15. The mold B plate 200 cooperates with the mold A plate 100, and they together enclose the molding cavity of the coating plate 10. The first molding part 210 is used to mold the lens placement hole 11, the second molding part 220 is used to mold the groove 14, the third molding part 230 cooperates with the second molding seat 120 on the mold A plate 100 to mold the positioning hole 15, and the fourth molding part 240 is used to mold the positioning column 16. The inlay pin 400 is fixed in the mold A plate 100 and is used to form the locking hole 12. This mold assembly can produce a drainage coating plate 10 with a specific shape and function. The fixing column 13 and the positioning hole 15 are used to fix the coating plate 10 in a specific position, the lens placement hole 11 is used to ensure the correct placement of the lens, and the groove 14 is used to form a drainage channel for the coating plate 10.

[0037] The principle of the present invention is as follows: a fixing column 13 is formed by the first molding seat 110 of the mold A plate 100, a positioning hole 15 is formed by the second molding seat 120 of the mold A plate 100 and the third molding part 230 of the mold B plate 200, the first molding part 210 of the mold B plate 200 forms a lens placement hole 11, the second molding part 220 of the mold B plate 200 forms a groove 14, the fourth molding part 240 of the mold B plate 200 forms a positioning column 16, and a locking hole 12 is formed in the mold A plate 100 by the inlay pin 400. These components work together to ensure that the coated plate 10 molded by the mold assembly has the required shape, function and precision.

[0038] In some embodiments, the first forming portion 210 is a projection 250 arranged in a rectangular array.

[0039] The bosses 250 are arranged in a rectangular array, which means that they are distributed on the mold according to a certain geometric regularity, which helps to ensure that the molded lens placement holes 11 are also regularly arranged on the coating plate 10.

[0040] Furthermore, a first protrusion 260 is provided on the boss 250 .

[0041] The first protrusion 260 can enhance the fixing stability of the lens in the lens placement hole 11 after molding, provide an additional support point, and ensure that the component will not shift during the molding process.

[0042] Furthermore, the first protrusion 260 is in the shape of a pancake, with a flat top and arc-shaped sides.

[0043] In some embodiments, in the longitudinal extension direction of the mold B plate 200 , the second forming portion 220 is a convex strip 270 connected to each of the bosses 250 arranged in a rectangular array.

[0044] The convex strip 270 is used to form the groove 14 , and the boss 250 is connected to the convex strip 270 , so that the formed lens placement hole 11 is connected to the groove 14 , and liquid can flow from the lens placement hole 11 into the groove 14 .

[0045] Furthermore, the cross-sections of both ends of the protrusion 270 are semicircular.

[0046] The semicircular cross section provides a smooth transition, which helps reduce stress concentration in the material during the molding process and reduces the risk of cracks and defects. In applications where the groove 14 is required to guide the flow of liquid, the semicircular cross section can provide better fluidity and reduce fluid resistance.

[0047] In some embodiments, the first forming seat 110 includes a second protruding portion 130 . The second protruding portion 130 includes a bump 140 with a semicircular cross section. The bump 140 is provided with a cylindrical groove 150 for forming the fixing column 13 .

[0048] The protrusion 140 with a semicircular cross section can form a recessed position in the coating plate 10 , and the fixing column 13 is placed in the recessed position.

[0049] In some embodiments, the second molding seat 120 and the third molding portion 230 are both cylindrical. When the mold A plate 100 and the mold B plate 200 are enclosed, the second molding seat 120 and the third molding portion 230 are docked.

[0050] A through hole can be formed in the coating plate 10 by connecting two cylinders. This structure is simple and improves production efficiency.

[0051] In some embodiments, the fourth forming portion 240 is a circular hole.

[0052] In some embodiments, the needle 400 includes a needle head 410 , which is in the shape of a rectangular parallelepiped.

[0053] The terms and words used in the above description and claims are not limited to their literal meanings, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
