The diameter of the outer peripheral end 39 of the smallest diameter of the sleeve 35 is 22 30, and even 22 · 50πωι. On the other hand, as shown in FIG. 2, the care of forming the substrate in the first stage of the optical disc substrate 42 is repeated. The diameter is 221 ° and even 〆40 °: and 'the position (radius) of the outer peripheral end portion 39 on the aforementioned annular projection 33' is provided on the aforementioned inner peripheral die-pressing plate 64, which is larger than the outer periphery of the 锷 65 Position 66 (radius R2) of the end portion, the radial direction of the outer edge of the knitting, or even the surface-if the 'simulated disc base ^ 44 is superimposed on the physical disc substrate 42', the burr 53 of the simulated vehicle substrate 44 must not be Overlapping on the same position on the data disc: the burr 49 of the plate 42. Furthermore, the diameter of the circumferential end 突起 39 of the ring-shaped protrusion is reduced to be smaller than the outer perimeter end 6 of the burr 65 and even the UG_ 'groove ends 48, 52 and the burr. 49,53, can form each other = position that does not R. In addition, regarding the groove surface of the sleeve and the groove surface of the fixed mold mirror panel, _ The mirror surface of the moving mold mirror panel is coated. Next, according to the embodiment of the optical disc substrate forming device 9, the lamination of the optical fiber substrate 42, the artificial silk substrate 44, and the forming of the optical disk substrate 42 will be described. 3. The manufacturing process of the optical disc 40 of the simulated optical disc substrate 44. In the description, the simulation of the optical disc substrate 乜 through the second forming mold 12 is mainly used and can be used for the formation of the data silk substrate 42. First, let's not reveal in the figure The injection device of the butterfly injection molding machine contacts the gate sleeve π of the second molding die 12 and allows the molten resin to be ejected into the groove 32 through the inside of the gate sleeve 18. Let the inside flow concentrically in a radial direction and fill the 1 = 12 μ268173 ^ ”injection molding machine injection molding machine, contact the second molding die 12 gate sleeve i8, let Xuan molten resin pass through the sleeve 18 and then shot the groove 32. Let the groove% The melt-transfer grease filled in the groove 32 flows concentrically in the direction of radiation, and in the cooling and solidification difficulty, the male knife 30 and the female knife 19 perforate the center opening 50 to form a simulated optical disc substrate 44. . Later 'event The tool 11 is fixed to the mold 10_, and then the air blow is supplied to the air blowing groove 36. The air blown from the air blowing groove 36 to the groove 32 has an annular protrusion 33 in the direction of the radiation inside the groove 32, so the air resistance is relatively low. According to the result of strong financial contact based on the direction of Fang Lin, the artificial optical disc substrate 44 can be coated more easily and quickly by removing the film from the groove of the rough-processed mirror panel 22 to open the artificial optical disc substrate, and then it is transported. In the Ming steaming device, the Ming information steaming section 43 is performed without information. In addition, while forming the artificial disc soil plate 44, the data disc substrate 42 and the data disc substrate 42 are also formed by the i-th forming mold 6. When the 41 is closed, the vapor deposition is similarly performed. The bottom plastic substrate 42 of the data disc and the bottom plastic substrate 44 of the emulation disc are each delivered to the bonding device. The information area f of the bottom substrate of the data disc f U1 is coated with an adhesive 45 and then the emulation disc substrate is superimposed. 、 = Red to W extension extension agent 45. At this time, the data optical fiber board 42 is similar to the real optical disc substrate 44, because the positions of the burrs 49 and 53 are not located at the same position. Therefore, the distance between the optical disc substrate 42 and the artificial optical disc substrate 44 does not exceed the second one. This ΐ 'rarely occurs due to the conflict between the burrs 49 and 53 ^ The adhesive 45 passes over the burrs 49 and 53 and does not enter the annular grooves 47 and 51 near the center opening 46 and 50 of M268173. . In addition, bubbles do not occur on the adhesive 45, so that an optical disc 40 having a beautiful appearance can be formed. This creation can be implemented in various changes, corrections, and improvements based on the knowledge of those skilled in the technology industry. In addition, this implementation form can be included in the scope of this creation as long as it does not depart from the main purpose of this creation. For example, a fixed mold can be mounted on an optical disc substrate forming device to form a second mold for simulating an optical disc substrate, a mirror plate having a grooved surface without an information section, and a sleeve forming an annular protrusion. In addition, as for the first forming mold for forming the data disc substrate in the disc substrate forming apparatus, a stamper may be mounted on the fixed mold. In addition, the diameter of the center hole of the mirror panel of the movable mold and the fixed mold can be reduced, and the inner portion of the non-information section can be formed on the surface of the mirror panel, and the annular protrusion can be formed as described above. At this time, an air blowing groove may be formed between the annular projection and the surface of the molding mirror panel without information. Furthermore, the first forming mold for forming the data optical disc substrate and the second forming mold for forming the dummy optical disc substrate may be mounted on the same injection molding machine in the optical disc substrate forming apparatus. In this case, the first and second molding dies may be integrated molding dies, or may be separate dies.
