It consists of putting CD-only-R, DVD-ROM, DVD-RAM, DVD-R, etc. Users of information recording when using optical discs for injection molding. [Previously, the system was directly cooled by a stream of media. In order to add more, each part of the root flow path into the document 6 is to ensure the flow in the mirror to improve the media and technology of the 3 pictures] The disc enters the fixed mold or through the opposite path, which in turn is filled in the rapid forming In order to prevent implementation, the above line of improvements are shown. The total cooling effector on the road of the panel, the cavity panel is used in the mirror panel, and the cavity is filled with the mold. The system is to use the mold mirror panel and the cooling grease to move the substrate. '. So cool. When the mirror panel is formed by injection molding and the master is placed on the movable mold, the mold is provided. In addition, because it is a temperature cycle for melting resin that is ejected from the disc substrate, it is necessary to uniformly cool the formed disc. It is generally known to require "for the optical disk substrate". Among them, Patent Document 1 and even On > form a vortex for 3 or 5 weeks to extend the distance and cooling medium rate. However, in the aforementioned patent, a flow path is formed into a vortex contact area, and a mirror plate of the disc substrate is added, and the fixed mold plate is formed with a molten tree in a cavity. Polycarbonate is used.

Creation description (2) degrees, the length of a flow path will be too long. In order to solve the aforementioned flow path, Patent Document 6 describes that the formed optical disc substrate on the side of the discharge hole is deformed. The solution disclosed in the solution 5 is to extend the total length of the cooling medium flow path on the inner peripheral side and in each of them. The distance and cooling time, due to the flow path on the mirror panel, are in the directions described in Patent Documents 4 and 5. For example, the part divided into the i / 4 discharge hole side will produce the temperature described in 5. This is also a problem when it is complicated. If a tubular flow path is provided, it is difficult to maintain the uniformity of each part. Patent Document 1: JP 2 0 0 1-71 3 5 1 (Patent Document 1, Figure 1, Figure 4, and Figure 6) Patent Document 2: Japanese Unexamined Patent Publication No. 6-8250 Figure 4) Patent Document 3: Excessive length. For example, the temperature of the cooling medium in a flow path will rise excessively, and the temperature of the mirror panel will change, causing problems. The problem of too long is a method in Patent Document 4. Patent Literature 4. Patent Literature is designed as a different system from the outer peripheral side. However, it does not take into account that there are fewer questions about ensuring the contact area between the media and the mirror panel, so the cooling efficiency is not good. In the case where the carrier A is radiated toward each mirror panel, the part on the side of the introduction hole is converted into a single electrode. In addition, in Patent Document 4, the flow paths formed in the outer mold member are different. In Patent Document 6, the introduced cooling medium is not completely discharged due to the temperature. (Second Eye Patent Scope Item 2, No. 5 Patent Application Scope Item 1

In this embodiment, six flow paths are formed on a large part of the mirror plate 31 in a direction intersecting with the cross-sectional direction from the inner peripheral portion 3 1 a to the outer peripheral portion 3 1 j 2; Each of the machine path f 2 and the second flow path 33 has a length of only three turns. In the bathing season, the first flow path 32 and the second flow path 33 are alternately arranged so that the cold = medium flows in the opposite direction, so that the temperature of each part of the mirror panel 3 丄 can be slightly uniform. In the embodiment shown in the fifth figure, the optical disc substrate of 12 ^ === is provided on the first flow path 3 2 and the second flow path 3 3 of the mirror panel 31 1. Panel 31's radial cross-section direction and the flow path width in a direction at a right angle to the cooling medium flow side 2) is formed as 3 5 dragons; however, the visibility of the second machine path is preferably formed between 3 mm and 4 · . In addition, the distance between the bottom of the path 3 2 and the second flow path 3 3 and the cavity surface is 8 ′, but it is preferably formed between 6 mm and 10 mm. In the example shown in Fig. 5, the two flow paths 3 2, 3 and 3 are respectively formed into tertiary vortices; however, the following methods can also be adopted: they are composed of three unified flow paths; The A ± ^ ^ of the different systems of the system are the same as those of the other systems, and the media systems of the other systems are the ones that flow in the opposite direction. In addition, in the foregoing embodiments, the values of all the flow systems are in the present invention φ, * not % Shi M α 1 Li Xi Xi Cheng / 1 ¾ like, Π Tongyuan ί Πί ί layout is limited to tanks. For example, a flow path constitutes. X, can also be in the mirror panel and the system into the following flow path: along

Page 20 M245045 V. Creation Instructions (17) In the circumferential direction, after about a week of weakness, bend the appointment! 80 ° is formed along the inner side of the flow path in a circumferential direction. However, the width of the flow path and the flow path of the mirror panel in the radial section are the same in the above embodiment. Next, a method of using the original optical disk substrate will be described. In the present invention, the mirror panel 5 is set to an average of 120 ° C or even 135t :, MD_R is used in the formation of DVD substrates such as MD-R, and the thickness of the base disc substrate for CD is half. 6 mm, and it is necessary to raise the temperature of the molten resin to be filled, and the temperature of the mirror panel 5 version 20 also needs to be relatively increased. However, if the mirror plate 5 is kept at a warm state in the forming mold of the optical disk substrate, the deformed substrate will be deformed. In the present invention, the temperature of the forming plates p, 17 of the optical disk substrate is used. It is maintained at about 13t, but the temperature of 17 and so on is maintained slightly uniform, so the deformation system in the tangential direction of the sixth plate is maintained within 0.15 degrees. Compared with 0.3 degrees, it shows a good value. [Creation effect] The forming mold of the creative disc substrate includes a mirror surface and a cavity surface. A cold vortex-shaped parallel flow path is formed on the mirror panel, and the parallel body flows in a plurality of adjacent flow paths in the same direction. However, the total contact area of the media and the mirror panel and the 21st page of the flow path, and then the number of the aforementioned methods, etc., are higher than those of the substrate of the shape mold 7 and so on. The remarkable shape in 1 7 is shown by the memetic mirror, which is related to the gauge plate, but in this mirror, the media flow path system contains cold. Therefore, the total extended distance can be confirmed, M245045 V. Creative Instructions (18) At the same time that the cooling efficiency is improved, the temperature difference of the cooling medium in the flow path is higher than a specific value, so as to further suppress the formed optical disc substrate. In addition, the width of each flow path in the direction of the radial section is especially large at 12cm. It is formed between the cavity surfaces of the 3 mm mirror panel to allow uniform cooling of the mirror panel. In addition, the noodles have improved the use of the master to set the shape to 120 ° C or even 135 ° C. In order to deform the length of each flow path, the inlet hole side and the parts of the discharge mirror panel are deformed. On the optical disc substrate, it is efficient to form the front parent fork in the direction of 4 · 5 and each stream size to be 6 mm, and it is effective to transfer the DVD, especially the transfer of DVD discs. Slightly uniform cooling does not occur at the specific value hole side. There are 6 flow paths in the media flow path; the bottom of the path and the front to 10 mm ° are shaped by the shape of the optical disc substrate substrate, even if the mold temperature is generated by the optical disc substrate M245045.
