It is.

溶融樹脂の射出成形におけるヒケ等の成形不良を防止する目的で、例えば特許文献１に記載の射出成形用金型では、金型のゲート近傍からキャビティの充填末端側に向けて延出するランナ溝部を設け、このランナ溝部内に摺動自在に設けたスライドコアを押圧機構によってキャビティに向けて押し込み可能とし、キャビティに充填された溶融樹脂を当該スライドコアでさらに加圧するようにしている。

Japanese Utility Model Publication No. 5-58248

複数個取りの射出成形用金型において品質が安定した成形品を得るためには、溶融樹脂を各キャビティへバランス良く充填する必要がある。しかし、上記従来の射出成形用金型で複数個取りとし、各キャビティへの充填バランスが均一でない場合、これを均一化するには金型の修正が必要となり手間を要する。
例えば、特開２００５−１３３７７２号公報には、自動車で使用される転がり軸受装置にセンサ付きシール装置が組み込まれたものが開示されている。このセンサ付きシール装置は固定側シール部材と回転側シール部材によって構成されており、このうち固定側シール部材を製造する際に複数個取りの射出成形金型を用いる場合がある。しかし、上述のように金型の修正が必要となった場合、転がり軸受装置の納期が長期化し、追加費用の発生により製品コストが高くなる。 In order to obtain a molded product with stable quality in a plurality of injection molds, it is necessary to fill the cavities with a good balance of molten resin. However, when a plurality of the above-described conventional injection molds are used and the filling balance into the cavities is not uniform, it is necessary to modify the molds to make the cavities uniform.
For example, Japanese Patent Laying-Open No. 2005-133772 discloses a rolling bearing device used in an automobile in which a seal device with a sensor is incorporated. This sensor-equipped sealing device is composed of a fixed-side seal member and a rotary-side seal member, and a plurality of injection molds may be used when manufacturing the fixed-side seal member. However, when the mold needs to be corrected as described above, the delivery time of the rolling bearing device is prolonged, and the product cost is increased due to the generation of additional costs.

本発明はこのような事情に鑑みてなされたものであり、各キャビティへの充填バランスを簡単に均一化できるようにして、製品の納期を長期化させず製品コストを抑えることができる複数個取りの射出成形金型、及びこの金型を用いた転がり軸受装置用センサ付きシール装置の固定側シール部材の製造方法の提供を目的とする。   The present invention has been made in view of such circumstances, and it is possible to easily equalize the filling balance in each cavity, and to reduce the product cost without prolonging the delivery time of the product. It is an object of the present invention to provide a method for manufacturing a fixed side seal member of a seal device with a sensor for a rolling bearing device using the mold.

本発明は上記目的を達成するために次の技術的手段を講じた。
すなわち、本発明は、溶融樹脂が充填される成形空間となる複数のキャビティ部と、射出シリンダーから供給される溶融樹脂を前記キャビティ部へ導く複数のランナー部と、前記複数のキャビティ部と前記複数のランナー部との間に設けられた複数のゲート部とを備える複数個取りの射出成形金型において、前記複数のランナー部に、前記溶融樹脂の流路断面積を変更可能にする流量調整手段が設けられていることを特徴とする。 In order to achieve the above object, the present invention takes the following technical means.
That is, the present invention includes a plurality of cavity portions that become molding spaces filled with a molten resin, a plurality of runner portions that guide the molten resin supplied from an injection cylinder to the cavity portion, the plurality of cavity portions, and the plurality of the plurality of cavity portions. In a multi-piece injection mold having a plurality of gate portions provided between the runner portions of the plurality of runner portions, a flow rate adjusting means for changing the cross-sectional area of the molten resin in the plurality of runner portions Is provided.

上記本発明によれば、溶融樹脂の流路断面積を変更可能にする流量調整手段によって、ランナー部を通過する溶融樹脂の流量を調整することができるので、複数個取りの当該射出成形用金型において、各キャビティへの溶融樹脂の充填バランスを金型の修正無しに均一化することができる。従って、溶融樹脂の充填バランスを簡単に均一化でき、製品の納期が長期化せず製品コストも抑えることができる。   According to the present invention, the flow rate of the molten resin that passes through the runner portion can be adjusted by the flow rate adjusting means that enables the flow path cross-sectional area of the molten resin to be changed. In the mold, the balance of filling the molten resin into each cavity can be made uniform without correcting the mold. Therefore, the filling balance of the molten resin can be easily made uniform, the delivery time of the product is not prolonged, and the product cost can be suppressed.

上記流量調整手段として、例えば前記溶融樹脂の流路へ向かって進退自在とされた可動板と、この可動板を所定位置で止める位置決め手段からなるものとすればよい。
この場合、可動板の流路への進入度合いにより溶融樹脂の流路断面積を変更することができる。また、上記位置決め手段は、例えば上記可動板に設けられた進退方向に長い長孔と、この長孔に挿通された位置決めピンとを有するものとすることができる。 The flow rate adjusting means may be composed of, for example, a movable plate that can be moved back and forth toward the flow path of the molten resin, and positioning means that stops the movable plate at a predetermined position.
In this case, the flow path cross-sectional area of the molten resin can be changed depending on the degree of entry of the movable plate into the flow path. Further, the positioning means may have, for example, a long hole provided in the movable plate and extending in the forward / backward direction, and a positioning pin inserted through the long hole.

上記本発明において、前記ゲート部は、前記射出成形金型に対して着脱自在とされたゲート部材により構成されていることが好ましい。
この場合、部品化された当該ゲート部材を取り替えることにより、ゲート部の形状や流路断面積を変更することができる。従って、上記流量調整手段に加え、当該ゲート部材を取り替えることによっても溶融樹脂の流量調整が可能となり、各キャビティへの充填バランスをより簡単に均一化することができる。 In the present invention, it is preferable that the gate portion is constituted by a gate member that is detachable from the injection mold.
In this case, the shape of the gate portion and the cross-sectional area of the flow path can be changed by replacing the parted gate member. Therefore, in addition to the flow rate adjusting means, the flow rate of the molten resin can be adjusted by replacing the gate member, and the filling balance to each cavity can be made uniform more easily.

また、本発明は、上記の射出成形金型を用いて、転がり軸受装置の固定側軌道輪に嵌合される環状の芯金の内周側に、センサを樹脂で一体化する転がり軸受装置用センサ付きシール装置の固定側シール部材の製造方法であって、前記射出成形金型は、前記芯金に前記センサを一体化する前段階として製作されるセンサ内蔵部材の成形空間となる第１キャビティ部と、前記芯金と前記センサ内蔵部材とを一体化する成形空間となる第２キャビティ部とを有しており、これら第１及び第２キャビティ部に溶融樹脂を同時に流し込んで、前記センサ内蔵部材と前記固定側シール部材とを同時に成形することを特徴とする。
上記本発明によれば、センサ内蔵部材と固定側シール部材が同時に得られるので当該固定側シール部材を効率良く製作することができ、さらに、各キャビティへの溶融樹脂の充填バランスを流量調整手段により簡単に均一化できるため、転がり軸受装置の納期を長期化させず、製品コストを抑えることができる。 In addition, the present invention provides a rolling bearing device in which a sensor is integrated with a resin on the inner peripheral side of an annular cored bar fitted to a stationary bearing ring of the rolling bearing device using the above injection mold. A method for manufacturing a fixed-side seal member of a sealing device with a sensor, wherein the injection mold is a first cavity serving as a molding space for a sensor built-in member manufactured as a stage prior to integrating the sensor with the core metal. And a second cavity portion that becomes a molding space for integrating the cored bar and the sensor built-in member, and molten resin is poured into the first and second cavity portions simultaneously to incorporate the sensor. The member and the fixed-side seal member are formed at the same time.

Since it can be easily made uniform, the delivery cost of the rolling bearing device is not prolonged, and the product cost can be suppressed.

上記のとおり、本発明の射出成形用金型によれば、流量調整手段によりランナー部を通過する溶融樹脂の流量を調整することができるので、各キャビティへの溶融樹脂の充填バランスを簡単に均一化することができ、製品の納期が長期化せず製品コストを抑えることができる。また、本発明の製造方法によれば、転がり軸受装置の納期を長期化させず、製品コストを抑えることができる。   As described above, according to the injection mold of the present invention, the flow rate of the molten resin passing through the runner portion can be adjusted by the flow rate adjusting means, so that the filling balance of the molten resin into each cavity can be easily and uniformly set. The product delivery time is not prolonged and the product cost can be reduced. Moreover, according to the manufacturing method of the present invention, the product cost can be suppressed without prolonging the delivery date of the rolling bearing device.

上記キャビティ部２は、センサ内蔵部材４０が成形される成形空間となる第１キャビティ部２１、及び固定側シール部材２６が成形される成形空間となる第２キャビティ部２２で構成されている。成形の際には、第１キャビティ部２１では、センサｓ等が所定の位置にセットされ、第２キャビティ部２２では芯金３０及びセンサ内蔵部材４０が所定の位置にセットされる。また、第一型１０には、中央のスプルー部５から二手に分かれるようにしてランナー部３が形成されており、各ランナー部３と各キャビティ部２１、２２との間にはこれらを結ぶゲート部４が設けられている。溶融樹脂は、図示しない射出成形機の射出シリンダーから供給され、スプルー部５及びランナー部３を経由して、ゲート部４を通りキャビティ部２１，２２に至る。   The cavity portion 2 includes a first cavity portion 21 serving as a molding space in which the sensor built-in member 40 is molded, and a second cavity portion 22 serving as a molding space in which the fixed-side seal member 26 is molded. During molding, the sensor s and the like are set at predetermined positions in the first cavity portion 21, and the core metal 30 and the sensor built-in member 40 are set at predetermined positions in the second cavity portion 22. The first mold 10 has a runner portion 3 formed so as to be separated from the central sprue portion 5 and a gate connecting the runner portion 3 and the cavity portions 21 and 22. Part 4 is provided. The molten resin is supplied from an injection cylinder of an injection molding machine (not shown), passes through the sprue portion 5 and the runner portion 3, passes through the gate portion 4, and reaches the cavity portions 21 and 22.

各ランナー部３のキャビティ側端部には、それぞれ流量調整手段６が設けられている。この流量調整手段６は、溶融樹脂の流路断面積を変更可能とするものであり、図３（ａ）に示すように二つの可動板７と、この可動板７を所定位置で止める位置決め手段からなるものである。可動板７は所要厚みを有する立方形状に形成されており、第一型１０（図２下側）に形成された凹部１０ａ内で、当該可動板７が流路へ向かって進退自在となっている。   A flow rate adjusting means 6 is provided at each cavity side end of each runner portion 3. The flow rate adjusting means 6 is capable of changing the flow path cross-sectional area of the molten resin. As shown in FIG. 3A, the two movable plates 7 and positioning means for stopping the movable plates 7 at predetermined positions. It consists of The movable plate 7 is formed in a cubic shape having a required thickness, and the movable plate 7 can advance and retreat toward the flow path in the recess 10a formed in the first mold 10 (lower side in FIG. 2). Yes.

The gate member 8 is formed in a block shape, and a gate portion 4 through which the molten resin passes is formed. Accordingly, several types of gate members 8 having different flow path cross-sectional areas and shapes are prepared in advance, and by replacing these gate members 8, the flow path of the molten resin can be changed by changing the flow path cross-sectional area and shape of the gate portion 4. Can be adjusted.

固定側シール部材２５を製造するには、一回目の射出工程で、第１キャビティ部２１及び第２キャビティ部２２に溶融樹脂を同時に流し込んで、センサ内蔵部材４０と固定側シール部材２５を同時に成形し、二回目の射出工程で、芯金３０に一回目の射出工程で得られたセンサ内蔵部材４０を一体化する。このような製造方法とすれば、転がり軸受装置７０の生産効率が向上する。また、上記のように構成された射出成形用金型１としているため、流量調整手段６及び部品化されたゲート部材８によって、射出シリンダーから供給される溶融樹脂の流量等を調整することができ、センサ内蔵部材４０を成形する第一キャビティ部２１や固定側シール部材２５を成形する第二キャビティ２２における溶融樹脂の充填バランスが均一でない場合であっても、金型の修正無しに充填バランスを均一化することができる。すなわち、非常に簡単な作業で充填バランスを均一化することができるようになっているので、固定側シール部材２５の製作に長期間を要さず、ひいては転がり軸受装置７０の納期が長期化せず製品コストも抑えることができる。なお、本発明は上記実施形態に限定するものではなく、例えば、可動板の大きさや位置、スライド機構、及びその固定方法を変更してもよい。   In order to manufacture the fixed-side seal member 25, in the first injection step, molten resin is poured into the first cavity portion 21 and the second cavity portion 22 at the same time, and the sensor built-in member 40 and the fixed-side seal member 25 are simultaneously molded. In the second injection process, the sensor built-in member 40 obtained in the first injection process is integrated with the core 30. With such a manufacturing method, the production efficiency of the rolling bearing device 70 is improved. Further, since the injection mold 1 is configured as described above, the flow rate of the molten resin supplied from the injection cylinder can be adjusted by the flow rate adjusting means 6 and the gate member 8 formed as a part. Even if the filling balance of the molten resin in the first cavity portion 21 for molding the sensor built-in member 40 and the second cavity 22 for molding the fixed-side seal member 25 is not uniform, the filling balance can be achieved without correcting the mold. It can be made uniform. That is, since the filling balance can be made uniform by a very simple operation, it does not take a long time to manufacture the fixed-side seal member 25, and thus the delivery time of the rolling bearing device 70 is prolonged. The product cost can also be reduced. In addition, this invention is not limited to the said embodiment, For example, you may change the magnitude | size and position of a movable plate, a slide mechanism, and its fixing method.
