Description

本発明は、樹脂成型金型でネジ孔を有する製品を形成させるためのネジ抜き金型及びその制御方法に関し、ネジ入れ子位置を判別して成型機の射出タイミングを制御するネジ抜き金型の制御方法に関する。   The present invention relates to a screw-off die for forming a product having a screw hole in a resin-molding die and a control method thereof, and control of the screw-off die that controls the injection timing of a molding machine by determining the screw nest position. Regarding the method.

従来、樹脂部品にインサート部品を用いることなくネジ孔を形成する方法が開発されている。図３はその１例として貫通ネジ孔を形成する場合の樹脂成型金型を示す図である。同図において、符号１は固定型２と可動型３とよりなる樹脂成形金型、４はキャビテイである。そして、固定型２にはネジ入れ子スライドユニット５と、該ネジ入れ子スライドユニット５を前後に駆動する図示なき油圧シリンダーが設けられており、該ネジ入れ子スライドユニット５には、ネジ入れ子６が設けられている。   Conventionally, a method of forming a screw hole without using an insert part in a resin part has been developed. FIG. 3 is a view showing a resin molding die when a through screw hole is formed as an example. In the figure, reference numeral 1 denotes a resin molding die composed of a fixed die 2 and a movable die 3, and 4 denotes a cavity. The fixed mold 2 is provided with a screw insert slide unit 5 and a hydraulic cylinder (not shown) that drives the screw insert slide unit 5 back and forth. The screw insert slide unit 5 is provided with a screw insert 6. ing.

そして、前記ネジ入れ子６は軸状をなし、その先端に雌ネジ形成用の雄ネジ７とバリ切り部８とが形成され、後端にはギア９が固定されている。そして、該ギア９はネジ入れ子スライドユニット５に設けられたモータ１０の駆動軸１１に固定されたピニオン１２に噛み合わされている。また、モータ１０には図示なきトルクセンサが設けられ、可動型３にはネジ入れ子６の先端部が挿入される凹部３ａが形成されている。   The screw insert 6 has a shaft shape, a male screw 7 for forming a female screw and a burr cutting portion 8 are formed at the tip, and a gear 9 is fixed at the rear end. The gear 9 is meshed with a pinion 12 fixed to a drive shaft 11 of a motor 10 provided in the screw insert slide unit 5. The motor 10 is provided with a torque sensor (not shown), and the movable die 3 is formed with a recess 3a into which the tip of the screw insert 6 is inserted.

上記のように構成された樹脂成形金型の作用を次に説明する。
先ず、第１工程は、金型１を閉じ、次いで固定型２からネジ入れ子スライドユニット５及び、ネジ入れ子６を油圧シリンダーにより前進させる。この場合ネジ入れ子６はモータ１０により回転されている。次に、第２工程は、ネジ入れ子６を可動型３にタッチさせてからキャビテイ４に対し樹脂成形機により樹脂の射出を開始する。次いで第３工程は金型１が冷却後、ネジ入れ子６を回転させながら後退させてから金型１を開き、製品を取り出すのである。 Next, the operation of the resin molding die configured as described above will be described.
First, in the first step, the mold 1 is closed, and then the screw insert slide unit 5 and the screw insert 6 are advanced from the fixed die 2 by a hydraulic cylinder. In this case, the screw insert 6 is rotated by a motor 10. Next, in the second step, after the screw insert 6 is touched to the movable mold 3, the resin is started to be injected into the cavity 4 by the resin molding machine. Next, in the third step, after the mold 1 is cooled, the screw insert 6 is rotated and retracted, and then the mold 1 is opened and the product is taken out.

そして、前記第２工程において、ネジ入れ子６の前進端は、ネジ入れ子スライドユニット５の油圧シリンダー近接スイッチからの信号を用いるか、モータ１０からのトルクアップ信号のどちらかにより確認する方法が採られている。また、第３工程におけるネジ入れ子６の後進端は、ネジ入れ子スライドユニット５の油圧シリンダー近接スイッチからの信号を用いる方法が採られている。   In the second step, the forward end of the screw insert 6 is confirmed using either a signal from the hydraulic cylinder proximity switch of the screw insert slide unit 5 or a torque-up signal from the motor 10. ing. Further, the backward end of the screw insert 6 in the third step employs a method using a signal from the hydraulic cylinder proximity switch of the screw insert slide unit 5.

ところが、前記第２工程のネジ入れ子６の前進端及び第３工程の後進端を確認するため、ネジ入れ子スライドユニット５の油圧シリンダー近接スイッチからの信号を用いる方法は、確実性は高いが金型構造が複雑となり、金型製作費の上昇、メンテナンスの手間が増大するという問題がある。なお、金型構造を簡単にすると熱可塑性樹脂には使用することができない。   However, in order to confirm the forward end of the screw insert 6 in the second step and the reverse end of the third step, the method using the signal from the hydraulic cylinder proximity switch of the screw insert slide unit 5 is highly reliable. There is a problem that the structure becomes complicated, the mold production cost increases, and the labor of maintenance increases. If the mold structure is simplified, it cannot be used for a thermoplastic resin.

また、前記第２工程におけるネジ入れ子６の前進端を確認するため、ネジ入れ子スライドユニット５のモータ１０からのトルクアップ信号により確認する方法は、ネジ入れ子６と金型の間に異物等がはさまってもトルクアップするため、間違って射出して金型を破損することがあるという問題がある。   In addition, in order to confirm the forward end of the screw insert 6 in the second step, a method of confirming with a torque-up signal from the motor 10 of the screw insert slide unit 5 is that foreign matter or the like is caught between the screw insert 6 and the mold. However, since the torque is increased, there is a problem that the mold may be damaged by injection by mistake.

引き続いて、本発明をその実施例を説明する。なお、本発明は、これらの実施例によって限定されるものでないことは言うまでもない。   Subsequently, examples of the present invention will be described. Needless to say, the present invention is not limited to these examples.

図１は本発明のネジ抜き金型の第１の実施例を示す概略図である。同図において、符号２０は固定型２１と可動型２２とよりなる樹脂成形金型、２３はキャビテイである。そして、固定型２１にはネジ入れ子スライドユニット２４と、該ネジ入れ子スライドユニット２４を前後に駆動する図示なき油圧シリンダーが設けられており、該ネジ入れ子スライドユニット２４には、ネジ入れ子２５と、該ネジ入れ子２５を回転駆動することができるサーボモータ２６が設けられている。   FIG. 1 is a schematic view showing a first embodiment of a screw-off mold according to the present invention. In the figure, reference numeral 20 denotes a resin molding die composed of a fixed die 21 and a movable die 22, and 23 denotes a cavity. The fixed mold 21 is provided with a screw insert slide unit 24 and a hydraulic cylinder (not shown) that drives the screw insert slide unit 24 back and forth. The screw insert slide unit 24 includes a screw insert 25 and the screw insert slide unit 24. A servo motor 26 capable of rotating the screw insert 25 is provided.

そして、前記ネジ入れ子２５は軸状をなし、その先端に雌ネジ形成用の雄ネジ２７と、バリ防止用のバリ切り部２８とが形成され、中間にはギア２９が固定されている。そして、前記ギア２９はネジ入れ子スライドユニット２４に設けられたサーボモータ２６の駆動軸３０に固定されたピニオン３１に噛み合わされている。また、サーボモータ２６にはサーボモータ制御盤３２が接続されている。また、可動型２２にはネジ入れ子２５の先端部が挿入される凹部２２ａが形成されている。   The screw insert 25 has a shaft shape, and has a male screw 27 for forming a female screw and a burr cutting portion 28 for preventing burr at the tip, and a gear 29 is fixed in the middle. The gear 29 is meshed with a pinion 31 fixed to a drive shaft 30 of a servo motor 26 provided in the screw insert slide unit 24. A servo motor control panel 32 is connected to the servo motor 26. In addition, the movable mold 22 is formed with a recess 22a into which the tip of the screw insert 25 is inserted.

上記のように構成されたネジ抜き金型を用いたネジ抜き金型の制御方法を次に説明する。先ず、サーボモータ制御盤３２に対してサーボモータ２６の回転数、回転トルク（入れ子のタッチトルク）、ネジ入れ子の位置を設定する。次に、樹脂成型の第１工程として、予めネジ入れ子スライドユニット２４を後退させておき、金型２０を閉じる。次いで固定型２１からネジ入れ子スライドユニット２４及び、ネジ入れ子２５を図示なき油圧シリンダーにより前進（矢印Ａ方向）させる。この場合ネジ入れ子２５はサーボモータ２６により回転されている。   Next, a control method of the screwing die using the screwing die configured as described above will be described. First, the rotational speed, rotational torque (nesting touch torque), and screw nesting position of the servo motor 26 are set for the servo motor control panel 32. Next, as a first step of resin molding, the screw insert slide unit 24 is retracted in advance, and the mold 20 is closed. Next, the screw insert slide unit 24 and the screw insert 25 are moved forward (in the direction of arrow A) by a hydraulic cylinder (not shown) from the fixed mold 21. In this case, the screw insert 25 is rotated by a servo motor 26.

次に、第２工程として、ネジ入れ子２５を可動型３にタッチさせる。この時、サーボモータ制御盤３２は、ネジ入れ子２５のタッチトルク及び位置とを確認する。もし、タッチトルク及び位置が設定値を満足する時はキャビテイ２３に樹脂を射出する。もし、タッチトルクが満足していても、位置が設定値を満足しない場合は、ネジ入れ子２５の先端が可動金型２２との間に異物を噛みこんでいるものとして樹脂の射出は行わない。   Next, as a second step, the screw insert 25 is touched to the movable mold 3. At this time, the servo motor control panel 32 confirms the touch torque and position of the screw insert 25. If the touch torque and the position satisfy the set values, the resin is injected into the cavity 23. If the position does not satisfy the set value even if the touch torque is satisfied, the resin is not injected on the assumption that the tip of the screw insert 25 is caught in the foreign object between the movable mold 22.

次に、樹脂の射出が終わり、金型２０が冷却後、ネジ入れ子２５を回転させながらネジ入れ子ユニット２４を後退（矢印Ｂ方向）させてから金型２０を開き、製品を取り出すのであるが、この時のネジ入れ子２５の後退端は、サーボモータ制御盤３２により指示され、この指示により、ネジ入れ子ユニット２４は停止される。   Next, after the injection of the resin is completed and the mold 20 is cooled, the screw insert unit 24 is moved backward (in the direction of arrow B) while rotating the screw insert 25, and then the mold 20 is opened and the product is taken out. The backward end of the screw insert 25 at this time is instructed by the servo motor control panel 32, and the screw insert unit 24 is stopped by this instruction.

図２は本発明の第２の実施例を示す図である。本実施例は前実施例とほぼ同様であり、異なるところは、ネジ入れ子２５の後退端を指示するため、該ネジ入れ子２５の中間にフランジ３３が設けられると共に、該フランジ３３に接触したときに作動するリミットスイッチ３４が固定型２１の所定位置に設けられていることである。   FIG. 2 is a diagram showing a second embodiment of the present invention. The present embodiment is substantially the same as the previous embodiment, except that a flange 33 is provided in the middle of the screw insert 25 to indicate the retracted end of the screw insert 25 and when the flange 33 comes into contact with the flange insert 33. The limit switch 34 to be operated is provided at a predetermined position of the fixed mold 21.

このように構成された第２の実施例の作用を次に説明する。本第２の実施例が第１の実施例と異なるところは、ネジ入れ子２５の後退端の検出のみであるので、この部分のみを説明する。図２において、ネジ入れ子２５が後退しフランジ３３がリミットスイッチ３４に当接すると、該リミットスイッチ３４からの信号によりサーボモータ制御盤３２を介してサーボモータ２６を停止させる。これにより、ネジ入れ子２５も停止する。その他の作用・効果は前実施例と同様である。   Next, the operation of the second embodiment configured as described above will be described. Since the second embodiment is different from the first embodiment only in detecting the backward end of the screw insert 25, only this portion will be described. In FIG. 2, when the screw insert 25 is retracted and the flange 33 comes into contact with the limit switch 34, the servomotor 26 is stopped via the servomotor control panel 32 by a signal from the limit switch 34. Thereby, the screw insert 25 is also stopped. Other operations and effects are the same as in the previous embodiment.

以上説明した第１、第２実施例においては、ネジ入れ子の制御に、サーボモータとサーボモータ制御盤を用いたことにより、ネジ入れ子の前進端の位置を確実に決定することができ、樹脂成型品の不良や、金型の破損を防止することができる。なお、本発明は、貫通したネジ孔のみならず、底付きのネジ孔にも応用することができる。   In the first and second embodiments described above, by using the servo motor and the servo motor control panel for the control of the screw insert, the position of the forward end of the screw insert can be determined reliably, and the resin molding It is possible to prevent defective products and damage to the mold. In addition, this invention can be applied not only to the screw hole which penetrated but the screw hole with a bottom.
