Definitions
- the present invention relates to an optical component manufacturing apparatus that molds an optical component. More specifically, the present invention relates to an optical component manufacturing apparatus that targets small parts (with an outer diameter of 2mn! To 12mm) and high precision (surface roughness Ra20nm or less). Background art
- optical parts such as objective lenses have been manufactured by injection molding of thermoplastic resin such as plastic (for example, see Patent Document 1 and Patent Document 2). Molding optical parts using plastic makes it possible to quickly produce products with uniform shapes, making them suitable for mass production. Optical devices that use plastic lenses are becoming smaller and higher in performance year by year, and the demand for smaller and more accurate plastic lenses is also increasing.
- the multi-cavity mold has one sprue part arranged in the center of the fixed mold, and multiple runners extend around the sprue part. In other words, the lens transfer part is provided symmetrically around the sprue part.
- Patent Document 1 Japanese Patent Laid-Open No. 11 42685
- Patent Document 2 JP 2001-272501 A
- the present invention has been made to solve the problems of the conventional optical component manufacturing apparatus.
- the problem is that it is possible to obtain a large number of small and high-precision optical components, and to ensure good transferability and shorten the manufacturing cycle. It is to provide a manufacturing apparatus.
- An optical component manufacturing apparatus made for the purpose of solving this problem has a fixed mold and a movable mold provided to be movable toward and away from the fixed mold.
- a runner with a projected area of lcm 2 to 12 cm 2 is constructed with the side mold and the movable mold pressed together, and the resin material is passed through the runner to the product transfer section between the molds.
- at least four optical components with an outer diameter in the range of 2 mm to 12 mm and an optical surface with a surface roughness of Ra20 nm or less can be picked up at least by one clamping. It is characterized by being.
- the optical component manufacturing apparatus of the present invention molds an optical component that is small (with an outer diameter in the range of 2 mn! To 12 mm) and high precision (the surface roughness of the optical surface is Ra 20 nm or less).
- This is a molding machine that can pick up at least four multi-pieces by one clamping. Note that the number of multi-chips should be 16 or less in consideration of ensuring good transferability.
- the projected area of the runner portion of a mold for molding such an optical component is defined to be within a range of lcm 2 to 12 cm 2 .
- the runner diameter and runner length are defined to satisfy the above range.
- Tsuma If the projected area of the runner is 12 cm 2 or less, the time required for cooling and solidifying the runner is short. If the projected area of the runner is 1 cm 2 or more, good transferability can be secured. Therefore, by ensuring that the projected area of the runner is within the above range, both good transferability can be secured and the manufacturing cycle can be shortened. Furthermore, since the volume of the runner part is small! /, The material cost of the waste part can be reduced.
- the outer end surface of the transfer member having a rectangular outer shape is attached to the base mold (fixed side mold, movable side mold). It can arrange
- the horizontal and vertical directions of the base mold can be matched with the adjustment direction of the axis deviation. For this reason, it is sufficient to evaluate the eccentricity of the molded product using two orthogonal axes. Furthermore, it is sufficient to adjust the position of the transfer material using two orthogonal axes. This makes it easy to evaluate the eccentricity of the molded product and adjust the position of the transfer member.
- the movable mold and the fixed mold are pressed against each other. It is better if the clamping force is 15 tons (150kN) or less. In other words, because the projected area of a part of the runner is small, the clamping force of the mold is 15 tons at most. Therefore, by applying the present invention to a so-called small molding machine with a clamping force of 15 tons or less, it is possible to save space and energy.
- the runner portion bends within a range of 1 to 3 times until the sprue partial force reaches the gate portion. It is better to have The bent part is a T-shaped branch or bent part. In other words, by providing a resin reservoir at each bend, the flow tip (low-temperature part) of the molten resin can remain in the resin reservoir. Therefore, the resin that flows into the product transfer section is hot and can maintain good transferability.
- a ring-shaped step around the optical axis of the optical component may be provided in the transfer portion of the optical surface of the transfer member.
- an optical path difference providing structure for example, a diffractive lens
- extremely good transferability is required to fill the grease up to the groove caused by the step. Therefore, if the present invention is applied to a manufacturing apparatus that takes a large number of optical components having an optical path difference providing structure on the transfer surface, it is possible to transfer well to the groove.
- the specific structure of the “optical path difference providing structure” is formed by, for example, forming an annular zone adjacent to the outside of the central region in the direction of the optical axis so that the optical path length is longer than the central region.
- the annular zone at the position of maximum effective diameter is formed by shifting in the optical axis direction so that the optical path length becomes longer with respect to the annular zone adjacent to the outside, and the annular zone at a position of 75% of the maximum effective diameter is This is a structure formed by shifting in the optical axis direction so that the optical path length becomes shorter with respect to the annular zone adjacent to the inside and the annular zone adjacent to the outside.
- the invention's effect [0016] According to the optical component manufacturing apparatus of the present invention, by reducing the projected area of the runner portion, both the reduction of the cooling time and the suppression of the transferability are achieved. Therefore, it is possible to obtain a large number of small and high-precision optical components, and an optical component manufacturing apparatus is provided that achieves both good transferability and shortening the manufacturing cycle. ing.

This improves the fluidity of the resin in the mold during molding and transfer, and the releasability (removability) when taking out the molded product from the mold.
- the molding machine 100 of this embodiment is a molding machine for multi-piece production, but for the sake of convenience of explanation, in the following explanation, it will be explained as a manufacturing process of one plastic lens.
- the molten resin flows into the product transfer section 50 through the sprue part, the runner part 52 and the gate part 51 in this order with both molds being in pressure contact.
- the movable mold 2 is separated from the fixed mold 1. Then, the molded product is taken out by an ejector or the like.

- amorphous polyolefin resin include Zeonex (registered trademark: Nippon Zeon) and Apel (registered trademark: Mitsui Chemicals).
- the refractive index of plastic resin decreases with increasing temperature, but the refractive index of most inorganic particles increases with increasing temperature. Therefore, there is a known technology that prevents these refractive index changes by causing these properties to cancel each other.
- inorganic particles having a size of 30 nm or less, preferably 20 nm or less, more preferably 10 to 15 nm are dispersed in the base resin.
- the runner cooling time is shorter than the product section cooling time. For this reason, the runner section cools faster than the product section. Therefore, the cooling and solidifying time of the runner does not affect the product cycle time.
- the projected area of the runner part is larger than 12 cm 2 , the cooling time of the resin in the runner part is longer than the cooling time of the product part. For this reason, it is necessary to ensure the cooling time of the runner section, which increases the product cycle time.
- the projected area of the runner 52 is smaller than 1.0 cm 2 , the runner diameter is inevitably small. Therefore, there is a concern about the poor transferability to the product transfer section 50.
- the projected area of the runner 52 is greater than 12.0 cm 2 , the runner diameter will inevitably increase. As a result, the time required for cooling and solidifying the resin in the runner section 52 becomes longer and the manufacturing cycle time becomes longer. Therefore, the projected area of the runner 52 is preferably in the range of 1.0 cm 2 to 12.0 cm 2 in order to shorten the manufacturing cycle time while ensuring transferability.
- the mold according to the present embodiment includes one sprue part at the center thereof.
- a plurality of runners 52 extend in a direction parallel to and perpendicular to the outer end face of the base mold, with a part of the sprue as the center.

- the sprue part 53 branches into two flow paths (runner part 52). Further, each runner 52 is further branched into two orthogonal flow paths, further branched into two orthogonal flow paths, and further provided with product transfer sections 50 respectively. In other words, the product transfer section 50 is reached by branching the runner section 52 twice.
- the sprue part branches into 53 forces and 4 flow paths (runner section 52). Furthermore, each runner 52 is further branched into two channels in the orthogonal direction, and a product transfer section 50 is provided at the end. In other words, the product transfer section 50 is reached by branching the runner section 52 once.

That is, the temperature of the molten resin flowing in the runner 52 is very high, 200 ° C to 300 ° C. On the other hand, the mold temperature is as low as 70 ° C to 150 ° C. Therefore, the temperature of the resin decreases at the flow front of the molten resin. This temperature drop becomes more pronounced as the runner diameter decreases. Therefore, as shown in Fig.

In addition, the runner length of the runner 52 is short and the transfer to the product transfer section 50 is good. Therefore, it is a molding machine capable of molding a large number of small and high-precision optical parts, and ensuring the transferability and molding cycle. An apparatus for manufacturing an optical component that achieves a shortened key is realized.

Further, the outer shape of the cavity 11 as viewed from the pressure contact surface is rectangular, and the outer end surface thereof is arranged in parallel with the outer end surface of the base mold 13. Therefore, the horizontal and vertical directions of the base mold can be matched with the adjustment direction of the axis deviation. Therefore, it is sufficient to evaluate the eccentricity of the molded product by measuring two orthogonal axes, and also adjusting the position of the transfer member by adjusting two orthogonal axes. Therefore, it is easy to evaluate the eccentricity of the molded product and adjust the position of the transfer member.
