本発明は、樹脂成型品を高精度に成型するために利用される、樹脂製品の精密加工装置と精密加工方法に関する。   The present invention relates to a precision processing apparatus and a precision processing method for resin products, which are used for molding a resin molded product with high accuracy.

樹脂成型品を作る方法には、切削加工と射出成型とが知られている。小型電子部品や光学部品のような精度の高い製品には切削加工が適する(特許文献1)。しかし、量産品については、コストの安い射出成型が採用される。また、射出成型でも高い精度が得られるような技術も各種開発されている(特許文献2)。

Cutting and injection molding are known as methods for producing a resin molded product. Cutting is suitable for highly accurate products such as small electronic components and optical components (Patent Document 1). However, low-cost injection molding is adopted for mass-produced products. Various techniques have also been developed to obtain high accuracy even by injection molding (Patent Document 2).
JP 2005-280200 A Japanese Patent Laid-Open No. 5-309564

切削加工によれば、任意の形状の製品が高い精度で製造できる。しかしながら、切削前に材料を正確に位置決めしてクランプするという準備作業が必要になる。また、自動運転で精密加工ができる切削加工装置は設備コストが高い。従って、生産性向上のために多数の切削加工設備を揃えることは難しい。一方、射出成型は大量生産に適するが、例えば非常に薄い部分、極細の突起部、あるいは先鋭な溝などを有する樹脂成型品は、歩留まりが低下する。また、数ミクロン以下の微細構造を持つ樹脂製品は、射出成型自体が困難である。   According to the cutting process, a product having an arbitrary shape can be manufactured with high accuracy. However, preparatory work is required to accurately position and clamp the material before cutting. Moreover, the equipment cost of a cutting apparatus capable of precision machining by automatic operation is high. Therefore, it is difficult to arrange a large number of cutting facilities for improving productivity. On the other hand, although injection molding is suitable for mass production, for example, a resin molded product having a very thin portion, an extremely thin protrusion, or a sharp groove has a low yield. Moreover, injection molding itself is difficult for a resin product having a fine structure of several microns or less.

本発明は、上記の課題を解決するために、射出成型の利点と切削加工の利点とを併せ持ち、微細構造を持ち生産性の高い樹脂製品の精密加工装置と精密加工方法を提供することを目的とする。   SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, an object of the present invention is to provide a precision processing apparatus and a precision processing method for a resin product that has both the advantages of injection molding and the advantages of cutting and has a fine structure and high productivity.

図1は実施例1の樹脂成型品の精密加工装置の概要を示す説明図である。図2は、図1に示した装置各部の斜視図である。
この図において、図1(a)は、射出機26と固定金型18と可動金型20の関係を示す側面図、図2(a)はこれらの斜視図である。各図に示すように、精密加工装置は、接離自在に合体される固定金型18及び可動金型20とを備える。図1(b)は、移動機構36により、可動金型20を固定金型18から離した状態の側面図である。射出機26は、固定金型18に樹脂通路22を通じて連結されている。可動金型20は移動機構36に支持されている。図2(a)に示すように、固定金型18及び可動金型20の当接面間には、キャビティ16が形成されている。射出機26は、このキャビティ16内に樹脂を射出する既知の機構の装置である。
1 is an explanatory view showing an outline of a precision processing apparatus for a resin molded product of Example 1. FIG. 2 is a perspective view of each part of the apparatus shown in FIG.
1A is a side view showing the relationship among the injection machine 26, the fixed mold 18 and the movable mold 20, and FIG. 2A is a perspective view thereof. As shown in the drawings, the precision machining apparatus includes a fixed mold 18 and a movable mold 20 that are detachably combined. FIG. 1B is a side view of the movable mold 20 separated from the fixed mold 18 by the moving mechanism 36. The injection machine 26 is connected to the fixed mold 18 through the resin passage 22. The movable mold 20 is supported by the moving mechanism 36. As shown in FIG. 2A, a cavity 16 is formed between the contact surfaces of the fixed mold 18 and the movable mold 20. The injection machine 26 is a device having a known mechanism for injecting resin into the cavity 16.

キャビティ16は、射出成型する樹脂成型品と同一外形を有している。キャビティ16は、例えば、図2(a)に示すように複数設けられる。これらはすべて同一形状でもよく、それぞれ異なる形状のものでもよい。もちろん、1組の固定金型18及び可動金型20にキャビティ16を個だけ設けてもよい。   The cavity 16 has the same outer shape as the resin molded product to be injection molded. For example, a plurality of cavities 16 are provided as shown in FIG. All of these may have the same shape or different shapes. Of course, only one cavity 16 may be provided in one set of fixed mold 18 and movable mold 20.

図1(c)は、移動機構36により可動金型20が移動された状態を示す側面図である。図2(b)は、切削装置32の斜視図である。可動金型20は、固定金型18から離れるときに、射出成型された樹脂成型品を固定金型18から離脱させて、そのまま保持する。移動機構36は、固定金型18を切削装置32の設置された位置まで移動させる。切削装置32は、可動金型20に保持された樹脂成型品を切削加工する。切削装置32には、例えば、3軸制御のNC加工機(Numerical Control machining)を使用する。図1(d)は、切削装置32を横置きした例を示す。この場合、移動機構36は、可動金型20を90度回転させて、樹脂成型品を切削装置32に対向させる。   FIG. 1C is a side view showing a state in which the movable mold 20 has been moved by the moving mechanism 36. FIG. 2B is a perspective view of the cutting device 32. When the movable mold 20 leaves the fixed mold 18, the injection molded resin molded product is detached from the fixed mold 18 and held as it is. The moving mechanism 36 moves the fixed mold 18 to a position where the cutting device 32 is installed. The cutting device 32 cuts the resin molded product held by the movable mold 20. For the cutting device 32, for example, a 3-axis control NC machine (Numerical Control machining) is used. FIG. 1D shows an example in which the cutting device 32 is placed horizontally. In this case, the moving mechanism 36 rotates the movable mold 20 by 90 degrees so that the resin molded product faces the cutting device 32.

図1(c)や図2(b)に示す例では、切削装置32に1台の切削工具30が設けられている。切削装置32は、切削工具30を進退させて、可動金型20に保持された樹脂成型品を切削加工する。可動金型20に複数のキャビティ16が設けられていて、複数の樹脂成型品が保持されているときは、切削工具30または、可動金型20を移動させて、複数の樹脂成型品を順次切削加工する。可動金型20と切削工具30とを自由に相対移動させることにより、複雑な切削加工が可能になる。全ての樹脂成型品に対して同一の切削加工を施してもよいし、それぞれ別々の切削加工を施してもよい。後者の場合、基本形状は同じ樹脂成型品を材料にして、複数種類の樹脂製品を連続的に自動的に生産できる。   In the example shown in FIG. 1C and FIG. 2B, the cutting device 32 is provided with one cutting tool 30. The cutting device 32 advances and retracts the cutting tool 30 to cut the resin molded product held by the movable mold 20. When a plurality of cavities 16 are provided in the movable mold 20 and a plurality of resin molded products are held, the cutting tool 30 or the movable mold 20 is moved to sequentially cut the plurality of resin molded products. Process. By freely moving the movable mold 20 and the cutting tool 30 relative to each other, complicated cutting can be performed. All the resin molded products may be subjected to the same cutting process or may be subjected to separate cutting processes. In the latter case, a plurality of types of resin products can be continuously and automatically produced using a resin molded product having the same basic shape as a material.

図2(c)の例では、切削装置32に複数の切削工具30が設けられている。例えば、可動金型20に設けられた8個のキャビティ16と対向する位置に、8台の切削工具30を配置して、各切削工具30を同時に動作させると、同時に並行して全ての樹脂成型品を切削加工できる。もちろん、動作タイミングをずらせても構わない。また、それぞれ別々の切削加工をしても構わない。なお、図1(c)や図2(b)に示すように、可動金型20に加工面が下向きになるように樹脂成型品を保持させた状態で、切削工具30により切削加工を施すと、樹脂成型品の切り屑が自然落下するので、効率よく切削加工ができる。   In the example of FIG. 2C, the cutting device 32 is provided with a plurality of cutting tools 30. For example, if eight cutting tools 30 are arranged at positions facing eight cavities 16 provided in the movable mold 20 and each cutting tool 30 is operated simultaneously, all the resin moldings are performed simultaneously in parallel. The product can be cut. Of course, the operation timing may be shifted. Moreover, you may perform a separate cutting process, respectively. In addition, as shown in FIG.1 (c) and FIG.2 (b), when it cuts with the cutting tool 30 in the state which hold | maintained the resin molded product so that the process surface may face down to the movable metal mold | die 20, it cuts. Since the chips of the resin molded product fall naturally, cutting can be performed efficiently.

この精密加工装置は、例えば、射出成型と切削加工を全自動の流れ作業で行うことができる。このために、切削加工済みの樹脂成型品を排出する処理が必要になる。図1(e)は排出機構34の側面図で、図2(d)はその斜視図である。切削装置32により仕上げられた樹脂製品13は、排出機構34により、可動金型20から外部に排出される。例えば、この排出機構34は、ホッパー34Aとベルトコンベア34Bを有する。切削装置32により加工された樹脂製品13は、可動金型20からホッパー34Aを介してベルトコンベア34B上に落下する。ベルトコンベア34Bは、樹脂製品13を所定箇所に運搬する。   This precision processing apparatus can perform, for example, injection molding and cutting by a fully automatic flow operation. For this reason, the process which discharges | emits the resin molded product after cutting is needed. FIG. 1 (e) is a side view of the discharge mechanism 34, and FIG. 2 (d) is a perspective view thereof. The resin product 13 finished by the cutting device 32 is discharged from the movable mold 20 to the outside by the discharge mechanism 34. For example, the discharge mechanism 34 includes a hopper 34A and a belt conveyor 34B. The resin product 13 processed by the cutting device 32 falls on the belt conveyor 34B from the movable mold 20 through the hopper 34A. The belt conveyor 34B conveys the resin product 13 to a predetermined location.

上記のように、樹脂成型品を可動金型で保持すると、高い精度で樹脂成型品をクランプすることができる。複数の樹脂成型品を一括して高い位置精度で配列し、クランプすることができる。従って、可動金型を3軸制御のNC加工機にセットすると、可動金型と切削工具の相対位置や向きを高精度に制御して精密な切削加工ができる。多数の材料をNC加工機に一つずつセットする作業が不用になる。高精度の加工が必要な部分だけ切削加工すればよいから、全体を切削加工するよりも、生産性が高い。故に、全体として、コストの安い精密部品を製造することが可能になる。切削工具の加工寸法精度は、最新のもので0.005ミクロンというものもある。プラスマイナス数ミクロン以下の加工精度が要求される場合には、本発明の装置が適するということが言える。   As described above, when the resin molded product is held by the movable mold, the resin molded product can be clamped with high accuracy. A plurality of resin molded products can be arranged and clamped together with high positional accuracy. Therefore, when the movable mold is set on a three-axis controlled NC machine, the relative position and orientation of the movable mold and the cutting tool can be controlled with high accuracy to perform precise cutting. The work of setting a large number of materials one by one on the NC processing machine becomes unnecessary. Since it is only necessary to cut only a portion that requires high-precision machining, productivity is higher than cutting the whole. Therefore, as a whole, it is possible to manufacture precision parts with low cost. The cutting tool has the latest machining dimension accuracy of 0.005 microns. It can be said that the apparatus of the present invention is suitable when machining accuracy of plus or minus several microns or less is required.

この装置は、例えば、図1に示した射出機26と固定金型18を1台備え、可動金型20を4台備える。図3(a)の合***置42に、射出機26と固定金型18を配置する。加工位置46に切削装置32を配置する。排出位置48に排出機構34を配置する。射出機26と切削装置32との間には、冷却機構を配置する。各可動金型20は、移動機構36により、合***置42から冷却位置44と排出位置48を経て合***置42に戻るように、それぞれ自動的に循環移動される。これにより、各工程が同時並行して進行する。

Each movable mold 20 is automatically circulated and moved by the moving mechanism 36 so as to return from the merged position 42 to the merged position 42 via the cooling position 44 and the discharge position 48. Thereby, each process advances simultaneously in parallel.

上記の冷却機構は、キャビティ16内に射出された樹脂24を、可動金型20で保持した状態で冷却する。自然放冷でもよいし、ファン等を用いた強制冷却でも構わない。射出成型された樹脂成形品12が可動金型に保持された状態で、できるだけ常温に近づくように冷却する。樹脂成型品の切削加工時の寸法精度を保持するためである。例えば、空気あるいは水等の冷媒を用いて樹脂成形品12を摂氏50度以下まで冷却するとよい。   The cooling mechanism cools the resin 24 injected into the cavity 16 while being held by the movable mold 20. Natural cooling may be used, or forced cooling using a fan or the like may be used. In a state where the injection molded resin molded product 12 is held in the movable mold, it is cooled as close to room temperature as possible. This is to maintain the dimensional accuracy during cutting of the resin molded product. For example, the resin molded product 12 may be cooled to 50 degrees Celsius or less using a refrigerant such as air or water.

また、移動機構36は、可動金型20の上面中央部に連結された支持部材のみ図示されているが、支持部材可動用のレール、稼動制御機構、電動機等を備えているとよい。図3(b)の例には、ターンテーブル状の移動機構37上に、4台の可動金型20を四角柱の側面に固定した機構を示した。各可動金型20は、アーム39により進退する。固定金型18に対向した可動金型20は、固定金型18と合体して射出成型に使用される。切削工具30に対向した可動金型20は、樹脂成型品の切削加工に使用される。なお、移動機構は、例えば、切削工具30が配置された場所で、可動金型20を図示しない加工用テーブルにセットする機構であってもよい。加工用テーブルは、自動的に可動金型20を位置決め固定して、切削工具30と相対移動し、加工精度を維持する。加工用テーブルは既知のNC加工機に使用されているものと同一でよい。可動金型20のいずれかの位置に、切削工具30に対する基準位置を設定するためのマークやピン等の標識を設けることが好ましい。   Moreover, although only the support member connected to the center part of the upper surface of the movable mold 20 is illustrated, the moving mechanism 36 may include a rail for moving the support member, an operation control mechanism, an electric motor, and the like. In the example of FIG. 3B, a mechanism in which four movable molds 20 are fixed to the side surfaces of a quadrangular prism on a turntable-like moving mechanism 37 is shown. Each movable mold 20 is advanced and retracted by an arm 39. The movable mold 20 facing the fixed mold 18 is combined with the fixed mold 18 and used for injection molding. The movable mold 20 facing the cutting tool 30 is used for cutting a resin molded product. The moving mechanism may be, for example, a mechanism that sets the movable mold 20 on a processing table (not shown) where the cutting tool 30 is disposed. The processing table automatically positions and fixes the movable mold 20 and moves relative to the cutting tool 30 to maintain the processing accuracy. The processing table may be the same as that used in known NC processing machines. It is preferable to provide a mark such as a mark or a pin for setting a reference position with respect to the cutting tool 30 at any position of the movable mold 20.

図4は精密加工装置で使用される固定金型と可動金型を示す断面図、図5の(a)は精密加工装置により射出成型された樹脂成型品を示す縦断面図、(b)は樹脂成型品を精密加工した樹脂製品を示す縦断面図である。
以下のような方法により、上記の精密加工装置を使用して樹脂製品13を製造する。先ず、図4(a)に示すように固定金型18及び可動金型20を重ね合わせて合体した状態で、キャビティ16内に樹脂を射出する。これにより、複数の樹脂成型品12を成型する。
4 is a cross-sectional view showing a fixed mold and a movable mold used in the precision processing apparatus, FIG. 5A is a longitudinal cross-sectional view showing a resin molded product injection-molded by the precision processing apparatus, and FIG. It is a longitudinal cross-sectional view which shows the resin product which processed the resin molded product precisely.
The resin product 13 is manufactured using the precision processing apparatus described above by the following method. First, as shown in FIG. 4A, the resin is injected into the cavity 16 in a state where the fixed mold 18 and the movable mold 20 are overlapped and united. Thereby, the some resin molded product 12 is shape | molded.

次に、図4(b)に示すように、可動金型20を持上げて固定金型18から切り離す。例えば、離型剤の調整により、各樹脂成型品12が固定金型18から離脱して、可動金型20に保持された状態になる。その後、複数の樹脂成型品12を保持した可動金型20を、移動機構36(図1)を用いて、図3に示す金型合***置42から冷却位置44に移動させる。そこで、樹脂成型品12を、例えば、摂氏40度程度まで冷却する。   Next, as shown in FIG. 4B, the movable mold 20 is lifted and separated from the fixed mold 18. For example, by adjusting the mold release agent, each resin molded product 12 is detached from the fixed mold 18 and is held in the movable mold 20. Thereafter, the movable mold 20 holding the plurality of resin molded products 12 is moved from the mold combination position 42 shown in FIG. 3 to the cooling position 44 using the moving mechanism 36 (FIG. 1). Therefore, the resin molded product 12 is cooled to, for example, about 40 degrees Celsius.

樹脂成型品を冷却した後、図1(c)に示すように、樹脂成型品12を保持した可動金型20を加工位置46(図3)に移動する。ここで、切削装置32の切削工具30により樹脂成型品12の切削加工を行う。例えば、図5(a)に示す樹脂成型品12では、切削部分12A、12B、12Cについて、微細加工が求められている。突起部14A、14Bは、例えば、幅Wが数ミクロンで高さが数十ミクロンのものである。凹部14Cも同様の寸法の溝である。切削部分12A、12B、12Cを切削することにより、図5(b)に示すような樹脂製品を仕上げることができる。樹脂製品の一部について、射出成型の寸法精度よりも高い面の平坦度が要求されるときにも、切削加工で仕上げることができる。   After cooling the resin molded product, as shown in FIG. 1C, the movable mold 20 holding the resin molded product 12 is moved to the processing position 46 (FIG. 3). Here, the resin molded product 12 is cut by the cutting tool 30 of the cutting device 32. For example, in the resin molded product 12 shown in FIG. 5A, fine machining is required for the cutting portions 12A, 12B, and 12C. The protrusions 14A and 14B have, for example, a width W of several microns and a height of several tens of microns. The recess 14C is a groove having the same size. By cutting the cutting portions 12A, 12B, and 12C, a resin product as shown in FIG. 5B can be finished. A part of the resin product can be finished by cutting when the flatness of the surface higher than the dimensional accuracy of the injection molding is required.

図6は本発明の装置の効果を説明する樹脂成型品の部分縦断面図である。
本発明の装置は、例えば、図の(a)に示すような、幅(W)が0.5μm 以上5μm以下の突起62A、62Bや、あるいは凹部62Cを有する樹脂製品の製造に特に威力を発揮する。例えば、数ミクロン以下の幅の突起や凹部は、射出成型では、図6の(b)に示すように、エッジの部分に空隙66が生じてしまう。樹脂の粘度等の関係で、これ以上の成型が困難である。図の一点鎖線70のように、切削加工すれば、これが実現する。
FIG. 6 is a partial longitudinal sectional view of a resin molded product for explaining the effect of the apparatus of the present invention.
The apparatus of the present invention is particularly effective in the manufacture of resin products having protrusions 62A and 62B having a width (W) of 0.5 μm or more and 5 μm or less, or recesses 62C, as shown in FIG. To do. For example, a protrusion or recess having a width of several microns or less causes a gap 66 at the edge portion as shown in FIG. Further molding is difficult due to the viscosity of the resin. This can be realized by cutting as shown by a dashed line 70 in FIG.

また、図の斜め孔62Dは、金型を対向させて合体させたり引き離したりする構造の射出成型機では成型できない。従って、可動金型に樹脂成型品を保持させて切削装置で加工することで、初めてこのような樹脂製品を製造できる。即ち、切削装置によれば、固定金型と移動金型の接合面に対して垂直でない斜め孔または突起を、自由に形成することができる。   Further, the oblique hole 62D in the figure cannot be molded by an injection molding machine having a structure in which the molds are opposed to each other and are combined or separated. Therefore, such a resin product can be manufactured for the first time by holding the resin molded product on the movable mold and processing it with a cutting device. That is, according to the cutting device, it is possible to freely form oblique holes or protrusions that are not perpendicular to the joint surface between the fixed mold and the movable mold.

以上の方法により、例えば、ポリアセタール、ポリカーボネート、ポリエチレンテレフタレート、ポリアリレート等による樹脂成型品のミクロンオーダーの超精密加工が可能になる。得られた製品は、精密光学部品、電子部品、超小型機構部品等、精密加工を必要とする様々な分野に利用できる。   By the above method, it becomes possible to perform micron-order ultraprecision processing of a resin molded product made of, for example, polyacetal, polycarbonate, polyethylene terephthalate, polyarylate, or the like. The obtained products can be used in various fields that require precision machining, such as precision optical parts, electronic parts, and micromechanical parts.

以上説明した本発明の樹脂製品の精密加工装置によれば、以下のような効果が期待できる。
(1)射出成型により得た樹脂成型品を、切削装置を使用して切削加工し、微細加工が必要な部分だけを仕上げるので、生産性が良く、かつ、高精度の樹脂製品を製造できる。
(2)可動金型に多数の樹脂成型品を保持して位置決めし、切削加工をするので、切削加工前に材料をクランプしたり位置決めしたりする作業を大幅に削減できる。
(3)射出成型の金型を単純な構造にできる。即ち、部分的に細かい溝や突起を設けるための複雑な金型加工が不用で、金型を安価に製造できる。
(4)同一の形状の樹脂成型品を複数射出成型して、切削装置を使用してそれぞれ別々に切削加工すると、複数種類の樹脂製品を同じ生産ラインで生産することかできる。しかも、金型を共通化できるので、設備コストも低減できる。
(5)可動金型を複数台使用して、射出成型、冷却、切削加工、排出、といった工程を連続させ、並行処理をさせると、生産性をより向上させることができる。
(6)樹脂成型品に対して、幅が0.5μm 以上5μm以下の突起や凹部、あるいは、固定金型と移動金型の接合面に対して垂直でない斜め孔または突起を形成できる。これにより、射出成型では不可能だった樹脂製品の効率的な製造が可能になる。
According to the precision processing apparatus for resin products of the present invention described above, the following effects can be expected.
(1) Since a resin molded product obtained by injection molding is cut using a cutting device and only a portion requiring fine processing is finished, a product with high productivity and high accuracy can be manufactured.
(2) Since a large number of resin molded products are held and positioned in the movable mold for cutting, the work of clamping and positioning the material before cutting can be greatly reduced.
(3) The injection mold can have a simple structure. In other words, complicated mold processing for partially providing fine grooves and protrusions is unnecessary, and the mold can be manufactured at low cost.
(4) When a plurality of resin molded products having the same shape are injection-molded and individually cut using a cutting device, a plurality of types of resin products can be produced on the same production line. In addition, since the mold can be shared, the equipment cost can be reduced.
(5) If a plurality of movable molds are used and the processes such as injection molding, cooling, cutting, and discharging are continued and processed in parallel, productivity can be further improved.
(6) A protrusion or recess having a width of 0.5 μm or more and 5 μm or less, or an oblique hole or protrusion that is not perpendicular to the joint surface between the fixed mold and the movable mold can be formed on the resin molded product. This makes it possible to efficiently manufacture resin products that were impossible with injection molding.
