Description

本発明は、プラスチック製品の成形方法(plastic product forming method)に関し、更に詳しくは、流体プラスチック及び磁気伝導性繊維を含む原材料の固化成形方法に関する。   The present invention relates to a plastic product forming method, and more particularly to a solidification method for raw materials including fluid plastics and magnetic conductive fibers.

従来の製品の製造方法は数多あるが、一部の方法ではプラスチックを原料として製造を行う。プラスチックは製品の製造に用いられるよくある原料であるが、プラスチックの構造強度は求められている強度に未だ達していない。従来の製造方法においては、プラスチック原料に繊維を添加することにより製品全体の強度を強化させている。   There are many conventional methods for manufacturing products, but some methods use plastic as a raw material. Plastic is a common raw material used in the manufacture of products, but the structural strength of plastic has not yet reached the required strength. In the conventional manufacturing method, the strength of the entire product is enhanced by adding fibers to the plastic raw material.

しかしながら、繊維がプラスチック原料中で分布される位置及び角度も製品の強度に影響を与える。従来のプラスチック製品の製造方式の多くは射出成形、押出成形等であるが、現在これら前記製造方式では、流速及び温度を利用して繊維の分布を推測しており、繊維の角度が調整できない。このため、プラスチック製品の機械的性質が掌握できなかった。   However, the position and angle at which the fibers are distributed in the plastic raw material also affects the strength of the product. Many of the conventional manufacturing methods for plastic products are injection molding, extrusion molding, and the like. At present, however, the fiber distribution is estimated using flow velocity and temperature, and the angle of the fibers cannot be adjusted. For this reason, the mechanical properties of the plastic product could not be grasped.

The embodiments described below do not limit the contents of the present invention described in the claims. In addition, all of the configurations described below are not necessarily essential requirements of the present invention.

本発明に係るプラスチック製品の成形方法及びプラスチック製品の成形設備１は、流体の原材料９の固化成形に応用され、原材料９として流体プラスチック９１及び複数の磁気伝導性繊維９２を含む（図１参照）。以下では、先ずプラスチック製品の成形設備１について説明する。流体プラスチック９１は熱可塑性プラスチックである。磁気伝導性繊維９２は、金属繊維、炭素繊維、またはニッケルめっきガラス繊維であり、金属繊維として、ステンレス鋼繊維、鋼繊維、及びニッケル繊維等を含み、炭素繊維として、炭素繊維の表面が金属に被覆されるもの（ニッケルめっき炭素繊維０．７μｍ）及びカーボングラファイト顆粒が堆積されるもの等を含む。   The plastic product molding method and plastic product molding equipment 1 according to the present invention is applied to solidification molding of a fluid raw material 9 and includes a fluid plastic 91 and a plurality of magnetic conductive fibers 92 as the raw material 9 (see FIG. 1). . In the following, first, the plastic product molding equipment 1 will be described. The fluid plastic 91 is a thermoplastic plastic. The magnetic conductive fiber 92 is a metal fiber, carbon fiber, or nickel-plated glass fiber, and includes stainless steel fiber, steel fiber, nickel fiber, etc. as the metal fiber, and the surface of the carbon fiber is made of metal as the carbon fiber. Including those to be coated (nickel-plated carbon fiber 0.7 μm) and those on which carbon graphite granules are deposited.

プラスチック製品の成形設備１は金型１０及び材料供給区２０を備え、金型１０は成形領域１１及び磁気領域１２を含む。磁気領域１２は成形領域１１の周囲に設置され、磁気領域１２は磁場Ｈを発生させ、磁場Ｈは成形領域１１を通過させる（図１参照）。   The plastic product molding equipment 1 includes a mold 10 and a material supply section 20, and the mold 10 includes a molding region 11 and a magnetic region 12. The magnetic region 12 is installed around the forming region 11, and the magnetic region 12 generates a magnetic field H, and the magnetic field H passes through the forming region 11 (see FIG. 1).

成形領域１１はダイコア１１１により形成される。すなわち、ダイコア１１１の内部空間が成形領域１１であり、ダイコア１１１の内部輪郭が成形後の製品の外形となる。成形領域１１は注入口１１２を更に備え、注入口１１２はダイコア１１１の内部空間及び材料供給区２０にそれぞれ接続される。磁気領域１２は、一対のスライダー１２１と、一対の磁石１２２と、一対の仕切りブロック１２３とを含む。スライダー１２１、磁石１２２、及び仕切りブロック１２３は成形領域１１の両側にそれぞれ設置される。仕切りブロック１２３はダイコア１１１に設置されると共にダイコア１１１の内部空間に近接させ、仕切りブロック１２３は磁場を透過させる材質で製造され、例えば、プラスチック、鉄、アルミニウム等である。２つの磁石１２２は２つのスライダー１２１にそれぞれ設置され、磁石１２２は永久磁石または電磁石である。スライダー１２１は成形領域１１の両側に滑動可能に設置される。本発明の好ましい実施形態では、磁石１２２は永久磁石であり、スライダー１２１により成形領域１１の磁場Ｈの大きさが調整されるか、或いは磁石１２２の成形領域１１における磁場Ｈが０になる。   The molding region 11 is formed by the die core 111. That is, the inner space of the die core 111 is the molding region 11, and the inner contour of the die core 111 is the outer shape of the product after molding. The molding region 11 further includes an inlet 112, which is connected to the internal space of the die core 111 and the material supply section 20, respectively. The magnetic region 12 includes a pair of sliders 121, a pair of magnets 122, and a pair of partition blocks 123. The slider 121, the magnet 122, and the partition block 123 are installed on both sides of the molding region 11, respectively. The partition block 123 is installed in the die core 111 and is brought close to the internal space of the die core 111, and the partition block 123 is made of a material that transmits a magnetic field, such as plastic, iron, and aluminum. The two magnets 122 are respectively installed on the two sliders 121, and the magnet 122 is a permanent magnet or an electromagnet. The slider 121 is slidably installed on both sides of the molding region 11. In a preferred embodiment of the present invention, the magnet 122 is a permanent magnet, and the magnitude of the magnetic field H in the molding region 11 is adjusted by the slider 121 or the magnetic field H in the molding region 11 of the magnet 122 is zero.

上述はプラスチック製品の成形設備１の描写である（図２参照）。以下では、プラスチック製品の成形方法の工程を説明する。
工程１において、原材料９が材料供給区２０から成形領域１１に注入される。材料供給区２０には大量の原材料９が保存され、原材料９は注入口１１２からダイコア１１１の内部空間に注入される。 The above is a depiction of the plastic product molding facility 1 (see FIG. 2). Below, the process of the molding method of a plastic product is demonstrated.
In step 1, raw material 9 is injected from material supply zone 20 into molding region 11. A large amount of raw material 9 is stored in the material supply zone 20, and the raw material 9 is injected into the internal space of the die core 111 from the injection port 112.

本発明の好ましい実施形態では、プラスチック製品の成形方法は射出成形の製造方法に応用可能である。よって、工程１は射出成形における充填（filling）工程であり、その原材料９は材料供給区２０のノズル（図示せず）から射出され、注入口１１２からダイコア１１１の内部空間に注入され、ダイコア１１１の内部空間全体に充満される。製造者は原材料９を注射する際に、磁気伝導性繊維９２の流体プラスチック９１における分布位置に対する噴射速度の影響の計算を行う。   In a preferred embodiment of the present invention, the plastic product molding method is applicable to an injection molding manufacturing method. Therefore, the process 1 is a filling process in injection molding, and the raw material 9 is injected from a nozzle (not shown) in the material supply section 20 and injected into the inner space of the die core 111 from the injection port 112. The whole interior space is filled. When the manufacturer injects the raw material 9, the manufacturer calculates the influence of the jet velocity on the distribution position of the magnetic conductive fiber 92 in the fluid plastic 91.

工程２において、磁場Ｈが成形領域１１に形成されることにより、原材料９中の磁気伝導性繊維９２の流体プラスチック９１における位置が調整される。図４に示すように、流体プラスチック９１が成形領域１１に最初に注入されると、磁場Ｈが磁気伝導性繊維９２の位置及び角度に影響を与え、磁場Ｈの方向が左から右になると（図面上での方向にすぎず、現実の方向を制限するものではない）、磁気伝導性繊維９２が常磁性物質である場合、磁気伝導性繊維９２は磁場Ｈの方向に従って回転する。磁気伝導性繊維９２が反磁性物質である場合、磁気伝導性繊維９２は磁場Ｈの反対方向に回転する。製造者は角度の方向調整の必要に応じて磁場Ｈの方向を決定させる。   In Step 2, the magnetic field H is formed in the molding region 11, whereby the position of the magnetic conductive fiber 92 in the raw material 9 in the fluid plastic 91 is adjusted. As shown in FIG. 4, when the fluid plastic 91 is first injected into the molding region 11, the magnetic field H affects the position and angle of the magnetic conductive fiber 92, and the direction of the magnetic field H changes from left to right ( If the magnetic conductive fiber 92 is a paramagnetic material, the magnetic conductive fiber 92 rotates according to the direction of the magnetic field H. When the magnetic conductive fiber 92 is a diamagnetic material, the magnetic conductive fiber 92 rotates in the direction opposite to the magnetic field H. The manufacturer determines the direction of the magnetic field H according to the necessity of adjusting the direction of the angle.

上述したように、本発明に係るプラスチック製品の成形方法は射出成形であり、工程２は圧力が保持される段階であり、原材料９の流体プラスチック９１が流体に保持されることで、磁気伝導性繊維９２が移動及び回転の調整の裕度を有する。製造者は繊維の配向の必要に応じて磁気伝導性繊維９２の好ましい角度及び位置を決定できる。   As described above, the plastic product molding method according to the present invention is injection molding. Step 2 is a stage in which pressure is maintained, and the fluid plastic 91 of the raw material 9 is retained in the fluid, so that the magnetic conductivity is maintained. The fiber 92 has a tolerance for adjustment of movement and rotation. The manufacturer can determine the preferred angle and position of the magnetically conductive fibers 92 as required by the fiber orientation.

磁気伝導性繊維９２の流体プラスチック９１における角度及び位置調整幅は、流体プラスチック９１の粘度係数の影響を受ける。流体プラスチック９１の粘度係数は、その温度及び圧力に関係しており、製造者は成形領域１１の温度及び圧力を調整させることにより、磁気伝導性繊維９２の位置及び角度の調整幅を調整可能である。   The angle and position adjustment width of the magnetic conductive fiber 92 in the fluid plastic 91 are affected by the viscosity coefficient of the fluid plastic 91. The viscosity coefficient of the fluid plastic 91 is related to its temperature and pressure, and the manufacturer can adjust the adjustment range of the position and angle of the magnetic conductive fiber 92 by adjusting the temperature and pressure of the molding region 11. is there.

上述したように、本発明の好ましい実施形態では、磁石１２２がスライダー１２１に設置され、製造者はスライダー１２１を利用して磁石１２２と成形領域１１との間の距離を調整させることにより、磁石１２２の成形領域１１における磁場Ｈの大きさが調整可能である。磁石１２２は電磁石であり、製造者は電力を調整させることにより磁場Ｈの大きさを調整可能である。   As described above, in a preferred embodiment of the present invention, the magnet 122 is installed on the slider 121, and the manufacturer uses the slider 121 to adjust the distance between the magnet 122 and the molding region 11, thereby causing the magnet 122. The magnitude of the magnetic field H in the molding region 11 can be adjusted. The magnet 122 is an electromagnet, and the manufacturer can adjust the magnitude of the magnetic field H by adjusting the electric power.

工程３において、原材料９が固化される。上述したように、本発明の好ましい実施形態では、原材料９は熱可塑性プラスチックであり、ダイコア１１１が冷却されることにより成形領域１１内の原材料９が冷却されて成形され、流体プラスチック９１が固化され、磁気伝導性繊維９２の位置も固定される。   In step 3, the raw material 9 is solidified. As described above, in the preferred embodiment of the present invention, the raw material 9 is a thermoplastic, and the die core 111 is cooled to cool the raw material 9 in the molding region 11 to be molded, and the fluid plastic 91 is solidified. The position of the magnetic conductive fiber 92 is also fixed.

工程４において、固化後の原材料９が成形領域１１から脱離される。固化成形された原材料９が離型され、金型１０中から取り出される。   In step 4, the solidified raw material 9 is detached from the molding region 11. The solidified raw material 9 is released from the mold 10.

工程５において、固化後の原材料９のスループレーン導電率または機械強度が測定される。磁気伝導性繊維９２を製造するための材質は導磁性に限らず、導電性でもよい。よって、磁気伝導性繊維９２が互いに接触すると固化後の原材料９が導電性質を有し、固化後の原材料９のスループレーン導電率を測定することにより、磁気伝導性繊維９２の原材料９における角度を掌握できる。或いは、固化後の原材料９の機械強度を測定することにより、回転後の磁気伝導性繊維９２が固化後の原材料に対する影響を確認できる。   In step 5, the through-plane conductivity or mechanical strength of the raw material 9 after solidification is measured. The material for manufacturing the magnetic conductive fiber 92 is not limited to the magnetic conductivity but may be conductive. Therefore, when the magnetic conductive fibers 92 come into contact with each other, the solidified raw material 9 has a conductive property, and by measuring the through-plane conductivity of the solidified raw material 9, the angle of the magnetic conductive fiber 92 in the raw material 9 can be determined. I can hold it. Alternatively, by measuring the mechanical strength of the raw material 9 after solidification, the influence of the rotated magnetic conductive fiber 92 on the raw material after solidification can be confirmed.

また、製造者は繊維配向テンソル（Fiber Orientation Tensior、 FOT）により磁場Ｈの磁気伝導性繊維９２に対する影響を計算可能である。繊維配向テンソルは、繊維配向テンソルが０である場合、磁気伝導性繊維９２が磁場Ｈの方向に平行し、即ち、磁気伝導性繊維９２が磁場Ｈの影響を受けて方向を転換していない。繊維配向テンソルが１である場合、磁気伝導性繊維９２が磁場方向に垂直になり、即ち、磁気伝導性繊維９２が磁場Ｈの影響を受けて方向を転換している。繊維配向テンソルは磁気伝導性繊維の回転角度の余弦関数の平均であり、その公式は以下の通りである。…ｎは磁気伝導性繊維９２の数量を表し、Θは磁気伝導性繊維９２と磁場Ｈとの夾角を表す。   Further, the manufacturer can calculate the influence of the magnetic field H on the magnetic conductive fiber 92 by a fiber orientation tensor (FOT). In the fiber orientation tensor, when the fiber orientation tensor is 0, the magnetic conductive fiber 92 is parallel to the direction of the magnetic field H, that is, the magnetic conductive fiber 92 is not changed its direction under the influence of the magnetic field H. When the fiber orientation tensor is 1, the magnetic conductive fiber 92 is perpendicular to the magnetic field direction, that is, the magnetic conductive fiber 92 is changed in direction under the influence of the magnetic field H. The fiber orientation tensor is the average of the cosine function of the rotation angle of the magnetic conductive fiber, and its formula is as follows. ... n represents the quantity of the magnetic conductive fibers 92, and Θ represents the depression angle between the magnetic conductive fibers 92 and the magnetic field H.

本発明の好ましい実施形態では、プラスチック製品の成形方法は、固化後の原材料９の断面から繊維配向テンソルの測定を行い、断面に保留される磁気伝導性繊維９２から磁気伝導性繊維９２と磁場Ｈとの間の夾角を直接測定させる。図５に示すように、磁気伝導性繊維９２が測定された断面に残留していない場合、磁気伝導性繊維９２の回転後に生じた孔部により測定を行う。図５は磁気伝導性繊維９２が回転後に生じた孔部を図示し、図５によると、磁気伝導性繊維９２の回転後に生じた孔部はほぼ楕円形を呈し、夾角Θは孔部の長い軸径Ｍ及び短い軸径Ｍが測定されることにより獲得され、且つ機器を使用して測定を行うことにより磁気伝導性繊維９２の垂直中心点Ｖｃ及び水平中心点ｈｃが獲得され、即ち、磁気伝導性繊維９２が存在する位置が獲得される。製造者はこれら前記数値に基づいて次回プラスチック製品を製造する際の磁場Ｈの大きさ及びノズルの流速を調整可能である。   In a preferred embodiment of the present invention, the plastic product molding method measures the fiber orientation tensor from the cross section of the raw material 9 after solidification, and from the magnetic conductive fibers 92 retained in the cross section to the magnetic conductive fibers 92 and the magnetic field H. The angle of depression between and is directly measured. As shown in FIG. 5, when the magnetic conductive fiber 92 does not remain in the measured cross section, the measurement is performed by the hole formed after the magnetic conductive fiber 92 is rotated. FIG. 5 illustrates a hole formed after the rotation of the magnetic conductive fiber 92. According to FIG. 5, the hole formed after the rotation of the magnetic conductive fiber 92 is substantially elliptical, and the depression angle Θ is a long hole. The vertical center point Vc and the horizontal center point hc of the magnetic conductive fiber 92 are obtained by measuring the shaft diameter M and the short shaft diameter M, and by performing measurement using the instrument, that is, magnetic The position where the conductive fiber 92 is present is obtained. The manufacturer can adjust the magnitude of the magnetic field H and the flow velocity of the nozzle when manufacturing the plastic product next time based on these numerical values.

上述のように、本発明に係るプラスチック製品の製造方法は、磁場を利用して磁気伝導性繊維の流体プラスチックにおける角度及び位置の調整を行うことにより、固化後の原材料の磁気伝導性繊維が制御されるため、製造者がプラスチック製品の機械的性質をより簡単に掌握可能になる。   As described above, the method of manufacturing a plastic product according to the present invention controls the magnetic conductive fiber of the raw material after solidification by adjusting the angle and position of the magnetic conductive fiber in the fluid plastic using a magnetic field. Thus, the manufacturer can more easily grasp the mechanical properties of the plastic product.
