Description of the Invention (1) [Application Field of the Invention] The present invention relates to a mold device for forming a compact disc such as a CD (compressed disc) or DVD (digital video disc). . [Description of known technology] Optical discs are generally formed by resin injection molding on their substrates. In this molding, the fixed mold and the movable mold which are respectively installed on the fixed plate and the movable plate of the injection molding machine are closed, and a product cavity is formed between the fixed mold and the movable mold. Injection of the molten thermoplastic resin, which is a molding material, into the product cavity. After the resin (ie, the optical disc) in the product cavity is cured in a mold adjusted to a specific low temperature, the fixed mold and the movable mold are injected into the cavity. Open and remove the formed disc. Furthermore, in order to form a specific low temperature of the product cavity in the mold, a temperature regulating passage for passing a cooling liquid is provided in the mold. However, in the forming of optical discs, high dimensional accuracy is required. However, as described above, during molding, molten resin is injected into the product cavity and filled at high speed, and a coolant is used to adjust the mold to a specific low temperature. Cooling and solidification, because the resin shrinks during cooling, etc., the thickness may not be maintained properly. This is because in the conventional mold device, the distances between the temperature adjustment path and the surface of the product cavity are all the same, so the temperature management of the surface of the product cavity may be insufficient, and as a result, the temperature distribution on the surface of the product cavity will not be formed. Causes of unevenness. In such a mold device, for example, at a location where the temperature adjustment path is dense, the average cooling capacity per unit area of the product cavity needs to be reduced. Conversely, in the case where the temperature adjustment path is relatively sparse, the Chinese paper standard (CNS) A4 specification (210X297 public envy) is applicable to the paper size.

At the position of the invention description (2), because the average cooling capacity per unit area of the product cavity is lower than the average 値, it must be improved The average cooling capacity per unit area of the product cavity. Therefore, at such positions where the mold temperature is not uniform, an improvement in temperature adjustment is expected. In view of this, in order to solve such problems, the purpose of the present invention is to provide a mold temperature that can optimize the product cavity. A mold device for forming a disc that improves the dimensional accuracy of the disc. [Summary of the invention] The reason is that the present invention is characterized by having a mold body with a fixed mold and a movable mold disposed opposite to the fixed mold, forming a product cavity between the fixed mold and the movable mold, and simultaneously An optical disc forming mold device provided with a temperature-adjusting passage for flowing cooling liquid in the body; wherein, at a position where the average cooling capacity per unit area of the product cavity is reduced according to the temperature-adjusting passage, the distance from the surface of the product cavity to the temperature-adjusting passage is reduced. The distance is increased, and at a position where the average cooling capacity per unit area of the product cavity is increased according to the temperature adjustment path, the distance from the surface of the product cavity to the temperature adjustment path is shortened. According to this structure, the cooling capacity is adjusted at a position where the average cooling capacity per unit area of the product cavity is increased or decreased according to the temperature adjustment passage, and the temperature distribution of the product cavity is optimized, and Improves disc size accuracy and more. Among them, it is best that the temperature-adjusting path is groove-shaped, and the distance is set to the distance between the bottom surface of the temperature-adjusting path that forms the groove and the surface of the product cavity. 0 This paper size applies to Chinese National Standard (CNS) A4 specification (210X 297 (Mm) --------- Approval of clothing-(Please read the notes on the back before filling this page) Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, printed by the Consumers' Cooperatives -5- 537959 A7 B7 V. Invention Note (3) (Please read the precautions on the back before filling in this page.) According to this structure, the mold is cooled by circulating a coolant through a groove-shaped temperature-regulating passage. In addition, because the temperature adjustment path is grooved, the distance can be set easily and accurately. Furthermore, it is preferable that the temperature control channel is formed concentrically with the product cavity to form a plurality of the same, and the distance is increased while communicating with the temperature control channel portion located on the inner side. According to this structure, the distance from the surface of the product cavity to the temperature-regulating passage at the communication path portion where the average cooling capacity per unit area should be reduced is increased. As a result, the disadvantages caused by excessive cooling in the communication path portion can be solved. Furthermore, it is preferable to shorten the distance at the outer periphery of the product cavity. According to this structure, the distance from the surface of the product cavity to the temperature adjustment path is shortened around the outside of the product cavity at a location with a large amount of heat radiation. As a result, the temperature distribution in the product cavity with a large amount of heat dissipation can be set to be uniform.

Description of the invention (1 Prepared state 'the distance between the bottom surface of the grooves forming the 3rd and 6th temperature adjustment passages 41 C and 41F' and the surface of the product cavity 3A C, compared with the bottom surfaces of the grooves 41A, 41B, 41D, 41E that form the other first, second, fourth, and fifth temperature adjustment passages, the distance from the surface of the product cavity 3A is shorter. Similarly, in the mold core block 24 In addition, the first to sixth temperature adjustment passage sections 45A, 45B, 45C, 45D, 45E, and 45F are also used to form the temperature adjustment passage 45. Therefore, the third temperature adjustment passage section 45C and the sixth temperature adjustment passage located at the outermost sides The portion 45F is designed to be opposed to the periphery of the product cavity 3, and the distance E between the bottom surface of the grooves of the third and sixth temperature adjustment passage portions 45C and 45F and the surface 3B of the product cavity is more than that of the other cavity. 1, 2, 4, 5 The front ends of the grooves of the temperature adjustment passages 45A, 45B, 45D, 45E and the surface of the product cavity 3B are short. In the second embodiment, the product filled in the product cavity 3 The resin in the cavity 3 is cooled by the coolant through the temperature-adjusting channels 41 and 45. At this time, there is generally a large amount of heat radiation around the periphery of the product cavity 3. Therefore, it is necessary to improve the cooling capacity of the coolant. In contrast, the third and sixth temperature adjustment passage sections 41C, 41F, 45C, 45F located at the outermost side and the product The distances C and E between the cavity surfaces 3A and 3B are shorter than the distances D and F of the other temperature regulating passages 41A, 41B, 41D, 41E, 45A, 45B, 45D, and 45E. According to the second embodiment, The distance from the surface of the product cavity 3 to the temperature adjustment path is formed to be shorter at the periphery of the product cavity 3. As a result, because the heat transfer distance of the coolant around the product cavity 3 will be shortened, so products with more heat dissipation The cooling capacity around the periphery of cavity 3 will be relatively increased, and the temperature distribution of cavity 3 of the product can be set to be uniform.
