インサート部材を有するモールド部材及びその製法 技術分野  Mold member having insert member and method for producing the same
本発明は、 インサート部材をインサートしたモ一ルド部材に関する。 背景技術  The present invention relates to a mold member having an insert member inserted therein. Background art
モールド部材のィンサート部材又は部品には、 いろいろな材料及び形 状の部品がインサートされているが、 インサ一ト部材と樹脂との線膨張 係数の差から発生する樹脂へのクラックを回避することは難しい。  Although inserts or parts of the mold member are inserted with various materials and shapes, it is not possible to avoid cracks in the resin due to the difference in linear expansion coefficient between the insert member and the resin. difficult.
そこでこのような解決手段として、 インサート部材と同等な線膨張係 数を持つ樹脂を使用しクラックを回避する方法がある。  Therefore, as a solution to this problem, there is a method of using a resin having a linear expansion coefficient equivalent to that of the insert member to avoid cracks.
また、 インサート部材をインサートモールドせずに、 後工程によりェ ポキシ材等の接着剤でモールド品とインサート部材を硬化接着し一体化 する方法も採られている。  In addition, a method has been adopted in which the molded product and the insert member are hardened and bonded with an adhesive such as an epoxy material in a later step without insert molding the insert member.
また、 予め軟質材でインサート部材を 1次モールドし、 次にその 1次 モールド品をインサート部材として 2次モールドするものがある。  Also, there is a type in which an insert member is firstly molded with a soft material in advance, and then the first molded product is secondarily molded as an insert member.
特開平 5 - 1 2 4 0 5 8号公報では、 樹脂内にガスを注入し、 インサ 一ト品の周辺の一部に空間部を形成させる構成が開示されている。 発明の開示 '  Japanese Patent Application Laid-Open No. 5-124058 discloses a configuration in which a gas is injected into a resin to form a space around a part of an insert product. DISCLOSURE OF THE INVENTION ''
従来のインサート部材をインサートするモールド部材には、 生産性や コス ト及び信頼性の面で問題がある。 例えば、 冷熱耐久性におけるイン サート部材と樹脂の線膨張係数の差から発生する樹脂のクラックを回避 するためには、 インサート部材と同等な線膨張係数を持つ特殊樹脂材を 使用しなければならず、 汎用榭脂材に比べ高コス トになる。 There is a problem in productivity, cost and reliability in a mold member into which a conventional insert member is inserted. For example, in order to avoid cracking of the resin due to the difference in the coefficient of linear expansion between the insert member and the resin in thermal durability, a special resin material with a linear expansion coefficient equivalent to that of the insert member is used. It must be used, which is more expensive than general-purpose resin materials.
インサート部材をインサートモールドせず、 予めモールドしたモール ド品に後工程で一体化する方法ではィンサ一ト部材の位置精度において ィンサ一トモールド品に比べ必然的に精度は悪くなり、 バラツキの少な い高位置精度を必要とするモールド製品には適用できなかった。更には、 後工程が必要となることから生産性でもコス ト高となる。  In the method of integrating the insert member into the pre-molded molded product in the post-process without insert molding, the accuracy of the position of the insert member is inevitably lower than that of the insert molded product, and there is less variation. It could not be applied to mold products that required positional accuracy. Furthermore, the cost is high in productivity because a post-process is required.
予めインサート部材を 1次モールドし、 次にその 1次モールド品をィ ンサート部材として 2次モールドするものでは、 1次モールド.品の樹脂 は 2次モールド品の樹脂の収縮力を緩和させるように軟質な材料を使用 し、 多重成形であることから成形金型費及び成形費もコスト高になる。 樹脂内にガスをモールド充填し、 インサート部材の周辺の一部に空間 部を形成させるものは、 空間の大きさや位置は樹脂の粘度に非常に左右 され、 流動的であり、 安定した空間を確実に所望するインサート部材の 外周, 角部, 突起部, 段差部の近傍に設けることが難しかった。 空間部 が適切な大きさで、 且つ、 適切な位置に形成されているかを外観からは 容易に判断することは出来ない。 更に空間の大きさによりィンサート品 とモールド品との間にがたやずれを有することになるため、 位置精度を 必要とするィンサ一ト成形品には適用できなかった。  In the case where the insert member is pre-molded in advance and then the primary molded product is used as the insert member for secondary molding, the primary mold resin is used to reduce the shrinkage of the resin of the secondary molded product. Since soft materials are used and multi-molding is used, the cost of molding dies and molding costs also increases. In the case where a resin is filled with a mold and a space is formed in a part of the periphery of the insert member, the size and position of the space is very dependent on the viscosity of the resin, and it is fluid and ensures a stable space It was difficult to provide the insert near the outer periphery, corner, protrusion, and step of the desired insert member. It is not possible to easily judge from the appearance whether the space is of an appropriate size and formed at an appropriate position. In addition, the gap between the insert product and the molded product may be displaced due to the size of the space, and therefore cannot be applied to an insert molded product that requires positional accuracy.

まず、 本発明が解決する課題について、 以下に、 説明する。  First, problems to be solved by the present invention will be described below.
第 1 7図に示す構造では、ィンサート部材をインサートモールドせず、 予めモ一ルドしたモールド品に後工程でインサート部材をモールド品に セッ トし、 インサート部材とモールド品の間に設けられている空間にェ ポキシ材の接着剤を塗布する。 塗布したモールド製品本体はエポキシ硬 化させるための熱処理が施され、 硬化したエポキシ材によりインサート 部材と樹脂は強固に接着し一体化する構造となっている。 しかし、 後か ら一体化する方法ではィンサート部材の位置精度においてィンサートモ —ルド品に比べ必然的に精度は悪くなり、 バラツキの少ない高位置精度 を必要とするモ一ルド製品には適用できなかった。 更には、 後工程が必 要となることから生産性でもコスト高となる。 In the structure shown in Fig. 17, the insert member is not insert-molded, and the insert member is set in a molded product that has been molded in advance in a post-process, and is provided between the insert member and the molded product. Apply epoxy adhesive to the space. The applied mold product body is subjected to heat treatment to harden the epoxy, and the insert and resin are firmly bonded and integrated with the hardened epoxy material. But later With the integrated method, the accuracy of the position of the insert member is inevitably lower than that of the insert model, and it cannot be applied to mold products that require high positional accuracy with little variation. Furthermore, since a post-process is required, the cost is also high in productivity.
一方、 第 1 8図に示す構造では、 予めインサート部材を 1次モールド し、次にその 1次モ一ルド品をインサート部材として 2次モールドする。 尚、 1次モールド品の樹脂は 2次モールド品の樹脂の収縮力を緩和させ る為、 軟質な材料を使用している。 しかし、 多重成形であることから成 形金型費及び成形費もコスト高になる。  On the other hand, in the structure shown in FIG. 18, the insert member is first molded in advance, and then the primary molded product is secondarily molded as the insert member. The resin of the primary molded product is made of a soft material to reduce the shrinkage of the resin of the secondary molded product. However, due to the multiple molding, the molding die cost and the molding cost are also high.
第 1 9図は樹脂内にガスをモールド充填する途中に注入口から注入し. インサート部材の周辺の一部に空間部を形成させる構成となっている。 しかし、 空間の大きさや位置は樹脂の粘度に非常に左右されるため、 流 動的であり安定した空間を確実に所望するィンサート部材の外周,角部, 突起部, 段差部の近傍に設けることが難しかった。  FIG. 19 shows a configuration in which a gas is injected into the resin from the injection port while the resin is being filled with the mold. A space is formed in a part of the periphery of the insert member. However, since the size and position of the space are greatly affected by the viscosity of the resin, it is necessary to provide a fluid and stable space in the vicinity of the outer periphery, corners, protrusions, and steps of the insert member, which ensures the desired space. Was difficult.
また、 空間部が適切な大きさで且つ、 適切な位置に形成されているか を外観からは容易に判断することは出来ない。 更に空間の大きさにより インサート品とモ一ルド品との間にがたやずれを有することになるため, 位置精度を必要とするィンサート成形品には適用できなかった。 ' 本発明の実施例を、 以下図面を使用して詳細に説明する。 なお、 本発 明は、 以下の実施例のみに限定されることなく用いられる。  Also, it is not possible to easily judge from the appearance whether the space is of an appropriate size and formed at an appropriate position. Furthermore, because of the size of the space, there is a gap between the insert product and the mold product, so it could not be applied to insert molded products that require positional accuracy. 'Embodiments of the present invention will be described below in detail with reference to the drawings. Note that the present invention is used without being limited to only the following examples.
【実施例 1】  [Example 1]

For this purpose, there are a region having voids and a region formed so as not to generate voids. Further, even if the region is formed so as to have no voids, voids exist when viewed microscopically, but voids that do not contribute to the object of the present invention are not considered.

第 2図はその部分の部分拡大図を示し、 第 3図はその時のインサート 部材 2 a, 2 b形状を示す。  FIG. 2 shows a partially enlarged view of this part, and FIG. 3 shows the shapes of the insert members 2a and 2b at that time.
また、 インサート部材近傍部 4を上面から見た正面図を第 4図にあら わし、 その時の樹脂 1 aとインサート部材 2 a, 2 bの断面図を第 5図 に示す。  FIG. 4 is a front view of the vicinity 4 of the insert member viewed from above, and FIG. 5 is a cross-sectional view of the resin 1a and the insert members 2a and 2b at that time.
尚、 第 3図のインサ一ト部材 2 a , 2 bには上面 1 0 , コーナ, 角部 1 1 , 外周側面 1 2それぞれを有している。  The insert members 2a and 2b shown in FIG. 3 have an upper surface 10, a corner, a corner portion 11, and an outer peripheral side surface 12, respectively.
空隙部 3 a, 3 b , 3 c , 3 dはインサート部材 2 a , 2 bの外周側 面 1 2特にコーナ, 角部 1 1 に設置しており、 空隙部 3 a , 3 b , 3 c , The voids 3a, 3b, 3c, 3d are installed on the outer peripheral surface 12 of the insert members 2a, 2b, especially at the corners and corners 11, and the voids 3a, 3b, 3c ,
3 d形状は予めモールドケース本体 1のモールド金型の駒で製作する。 その駒の空隙部 3 a, 3 b , 3 c, 3 d形状の内側にはインサート部材The 3d shape is manufactured in advance with the mold die piece of the mold case body 1. Insert members inside the gaps 3a, 3b, 3c, 3d of the piece
2 a, 2 bをインサートする形状が彫り込まれており、 空隙部 3 a ,The shape to insert 2a, 2b is engraved, and the gap 3a,
3 b , 3 c, 3 d形状とインサート部材 2 a, 2 bのコーナ, 角部 1 1 及び外周側面 1 2の合わせ面は密接している。 これによりインサ一トモ ールド後、 ィンサート部材 2 a , 3b, 3c, 3d shapes and inserts 2a, 2b corners, corners 1 1 And the mating surface of the outer peripheral side surface 1 and 2 is close. As a result, after the insert molding, the insert member 2a,
2 bのコーナ,角部 1 1及び外周側面 1 2に隣接して空隙部 3 a , 3 b , 2b corners, corners 1 1 1 and voids 3a, 3b,
3 c , 3 dが形成される。 また、 同時に空隙部 3 a, 3 b , 3 c , 3 d それぞれの間に樹脂 l aとインサート部材 2 a, 2 bを連続モールドし た樹脂押え部 9 a, 9 b , 9 c , 9 dも合わせて形成される。 尚、 イン サート部材 2 a , 2 bと樹脂押え部 9 a, 9 b , 9 c , 9 dの間に空隙 は無い。 3 c and 3 d are formed. At the same time, the resin holding portions 9a, 9b, 9c, 9d in which the resin la and the insert members 2a, 2b are continuously molded between the gaps 3a, 3b, 3c, 3d, respectively. It is formed together. There is no gap between the insert members 2a, 2b and the resin holding parts 9a, 9b, 9c, 9d.
通常、 冷熱時に樹脂は収縮するため樹脂内部に線膨張係数の異なるィ ンサート部材があると、 樹脂の収縮が拘束され樹脂内部に収縮応力が働 き歪みが発生し、 場合によってはクラックにいたる。 第 4図の空隙部 3 a , 3 b, 3 c , 3 dは榭脂 1 aの収縮時、 第 6図, 第 7図のように 収縮樹脂部 1 3 a, 1 3 b , 1 3 c , 1 3 dがインサート部材 2 a, Normally, the resin shrinks during cooling, so if there is an insert member with a different coefficient of linear expansion inside the resin, the shrinkage of the resin will be restrained and shrinkage stress will act inside the resin, resulting in distortion and, in some cases, cracking. The voids 3 a, 3 b, 3 c, and 3 d in FIG. 4 are the shrinkable resin parts 13 a, 13 b, and 13 c as shown in FIGS. 6 and 7 when the resin 1 a shrinks. , 1 3 d is the insert member 2 a,
2 b側に収縮するため、 空隙部 3 a , 3 b , 3 c , 3 dは樹脂内部の収 縮応力及び歪みを吸収して緩和することが出来る。 Since it shrinks to the 2b side, the voids 3a, 3b, 3c, 3d can absorb and reduce the shrinkage stress and strain inside the resin.
歪みを吸収して緩和する空隙部 3 a, 3 b , 3 c , 3 d形状において は、 特に限定されないがインサートされるインサート部材 2 a , 2 bの 板厚方向に樹脂を包み込む。 しかし、 少なくともインサート部材上面 1 0などの片面を露出させる必要があり、 インサート部材 2 a , 2 の 外周側面 1 2に対し複数に分割し、 所望する位置に設置する。 空隙部 The voids 3a, 3b, 3c, 3d, which absorb and relax the distortion, enclose the resin in the thickness direction of the insert members 2a, 2b to be inserted, although not particularly limited. However, it is necessary to expose at least one surface such as the upper surface 10 of the insert member, and the insert member 2a, 2 is divided into a plurality of outer peripheral side surfaces 12 and installed at desired positions. Void
3 a, 3 b , 3 c, 3 dはインサート部材 2 a, 2 bの外周側面 1 2に 密接に配置し、インサート部材 2 a, 2 bの形状に沿って一様に設ける。 これは、 厚み方向においては板厚と同じ深さ、 好ましくは板厚以上に大 きく設定する。 尚、 空隙部 3 a, 3 b , 3 c, 3 dの幅方向はインサー ト部材 2 a, 2 bと榭脂 1 aの線膨張係数差を十分回避できる大きさが 設定されていればよい。 インサ一ト部材 2 a, 2 bの外周側面 1 2に対 する空隙部 3 a , 3 b , 3 c , 3 dの設置割合は高いほど緩和効果があ り、 樹脂押え部 9 a , 9 b , 9 c, 9 dは必要最小限で設置するのが好 ましい。 更に空隙部 3 a, 3 b, 3 c, 3 dを収縮応力集中するィンサ 一ト部材 2 a, 2 bのコ一ナ, 角部 1 1に設けることで、 歪みを吸収し て緩和するのに最も高い効果を得ることが出来る。 3a, 3b, 3c, 3d are closely arranged on the outer peripheral side surface 12 of the insert members 2a, 2b, and are provided uniformly along the shape of the insert members 2a, 2b. This is set to the same depth as the plate thickness in the thickness direction, preferably larger than the plate thickness. The width of the gaps 3a, 3b, 3c, 3d is large enough to avoid the difference in linear expansion coefficient between the insert members 2a, 2b and the resin 1a. It only has to be set. The higher the installation ratio of the gaps 3a, 3b, 3c, 3d with respect to the outer peripheral side surface 12 of the insert members 2a, 2b, the more effective the effect is, and the resin holding parts 9a, 9b , 9c and 9d are preferably installed at the minimum necessary. In addition, the voids 3a, 3b, 3c, and 3d are provided in the corners and corners of the insert members 2a and 2b that concentrate the contraction stress, thereby absorbing and relaxing the strain. The highest effect can be obtained.
尚、 コーナ, 角部 1 1の収縮応力集中部はインサート部材 2 a, 2 b の形状により、発生する樹脂の収縮力の歪み量を事前に把握できるた 、 応力緩和に必要な大きさの空隙部 3 a, 3 b , 3 c, 3 dを予めモール ド金型に設定することができ、 所望する位置に容易に且つ、 精密に精度 良く配置することが可能である。  Note that the shrinkage stress concentration portion of the corners and corners 11 can be grasped in advance by the shape of the insert members 2a and 2b, and the amount of shrinkage of the generated resin shrinkage force can be grasped in advance. The parts 3a, 3b, 3c, 3d can be set in the mold in advance, and can be easily and precisely arranged at a desired position.
また、このような空隙は金型形状で決めるためィンサー卜部材の形状, 配列,—個数に制約を受けず、 比較的自由に設計し配置することも容易に 可能である。  In addition, since such a gap is determined by the shape of the mold, the shape, arrangement, and number of the insert members are not restricted, and it is easy to design and arrange relatively freely.
更には、 空隙部 3 a , 3 b , 3 c , 3 dを配置するには、 必然的に金 型とインサート部材 2 a, 2 bは密接に精度良く合わせることになるた め、 インサ一ト部材 2 a, 2 bの金型への位置決めも高精度となり、 結 果的にはモール 後のモ一ルドケースにおいて、 インサート部材 2 a , 2 bの位置精度を高精度に保持することが可能となる。  Furthermore, in order to arrange the gaps 3a, 3b, 3c, 3d, the mold and the insert members 2a, 2b are inevitably closely matched with each other with high accuracy. The positioning of the members 2a and 2b to the mold also becomes highly accurate, and as a result, the position accuracy of the insert members 2a and 2b can be maintained with high accuracy in the mold case after the molding. Become.
樹脂押え部 9 a , 9 b , 9 c , 9 dは、 ィンサ一ト部材 2 a , 2 bの 外周側面 1 2に複数箇所配置するもので、 インサート部材 2 a , 2 bに 対して、 同じ大きさで対称的に設置させていることが好ましい。.  The resin holding parts 9a, 9b, 9c, 9d are arranged at a plurality of locations on the outer peripheral side surface 12 of the insert members 2a, 2b, and are the same as the insert members 2a, 2b. It is preferable to arrange them symmetrically in size. .
同じ大きさの樹脂押え部 9 a, 9 b , 9 c , 9 dが対称的に設置され ることにより、 樹脂押え部 9 a, 9 b , 9 c , 9 dの収縮力はインサー ト部材 2 a, 2 bに対し、 互いに打ち消し合う方向に働き、 好ましくは 互いの収縮力の向きが一直線上であればインサート部材 2 a , 2 bに変 則的な応力を発生させることもない。 結果的にインサート部材 2 a , 2 bのインサートモールド後における、 冷熱収縮時の位置ずれを抑制す ることが可能となる。 Since the resin holding portions 9a, 9b, 9c and 9d of the same size are symmetrically installed, the contraction force of the resin holding portions 9a, 9b, 9c and 9d is reduced by the insertion member 2. For a and 2 b, they work in directions that cancel each other out, preferably If the directions of the contraction forces are on a straight line, no irregular stress is generated on the insert members 2a and 2b. As a result, it is possible to suppress displacement during cold shrinkage after insert molding of the insert members 2a and 2b.
本発明品のモールドケース本体 1の製造方法としては、 特に限定され ないが、 モ一ルドケース本体 1の要求される冷熱耐久性により樹脂の材 質は、 一般の汎用樹脂から特殊樹脂まで幅広く選択することが出来る。 また、金型内にインサートされるインサート部材の材質としては、金属, セラミックス,樹脂、あるいはこれらの材料を組み合わせた複合材料等、 特に限定されない。 更に形状においても角形, 丸形, 多角形, 扇形, 半 円形, 球形, 円柱形, パイプ形, 異形のブロック形、 等自由に選択でき る。  The method of manufacturing the molded case body 1 of the present invention is not particularly limited, but the resin material is selected from a wide range of general-purpose resins to special resins due to the required cooling and heat resistance of the molded case body 1. I can do it. Further, the material of the insert member inserted into the mold is not particularly limited, such as metal, ceramics, resin, or a composite material combining these materials. In addition, the shape can be freely selected such as square, round, polygon, sector, semicircle, sphere, cylinder, pipe, irregular block, etc.
ここで本発明について、更なる詳細を第 1 4図〜第 1 9図で説明する。 第 1 4図〜第 1 6図は本発明の上記空隙が設けられていない構成であり、 インサー卜部材 4 2 a , 4 2 bの外周側面がほぼ全面にわたり樹脂 41 a に包み込まれている。 この状態で冷熱時の樹脂 4 1 a収縮はィンサ一ト 部材 4 2 a, 4 2 bで拘束される為、 樹脂 4 1 a内部に収縮応力による 歪みが増大し、 樹脂 4 1 aが耐えきれず第 1 5図中のようなクラック 4 5が発生し、 樹脂 4 1 aの破壊にいたる。 尚、 第 1 5図中の 44 a , 44 b , 44 c , 44 d , 44 eはインサート部材 4 2 a , 4 2 bをモ 一ルド金型にセッ トするためのインサ一ト押え部を示す。  The present invention will now be described in further detail with reference to FIGS. 14 to 19. FIGS. 14 to 16 show a configuration of the present invention in which the above-mentioned space is not provided, and the outer peripheral side surfaces of the insert members 42 a and 42 b are almost entirely covered with the resin 41 a. In this state, the shrinkage of the resin 41a during cooling is restrained by the insert members 42a, 42b, so the distortion due to the shrinkage stress inside the resin 41a increases, and the resin 41a can withstand. First, cracks 45 occur as shown in Fig. 15 and the resin 41a is destroyed. In addition, 44a, 44b, 44c, 44d, 44e in Fig. 15 are insert holding parts for setting the insert members 42a, 42b in the mold. Show.
• よって、 これを回避する一つの手段としてィ'ンサ一ト部材と同等な線 膨張係数を持つ樹脂を使用しクラックを回避する方法がある。 しかし、 ィンサート部材と同等な線膨張係数を持つ特殊樹脂材は汎用樹脂材に比 ベ高コストになる問題があった。 また、 第 1 7図の様にインサート部材 5 2 a, 5 2 bをインサートモ ールドせずに、 後工程によりエポキシ材 5 3の接着剤で樹脂 5 1 aとィ ンサート部材 5 2 a, 5 2 bを硬化接着し一体化する方法も採られてい るが、 後かち一体化する方法ではィンサート部材 5 2 a , 5 2 bの位置 精度においてィンサ一トモ一ルドに比べ必然的に精度は悪くなり、 バラ ツキの少ない高位置精度を必要とするモールド部材には適用できなかつ た。 更には、 後工程が必要となることから生産性でもコス ト高となって いた。 • Therefore, as one means of avoiding this, there is a method of using a resin having a linear expansion coefficient equivalent to that of the insert member to avoid cracks. However, the special resin material having the same linear expansion coefficient as the insert member has a problem that the cost is higher than that of the general-purpose resin material. Also, as shown in Fig. 17, the insert members 52a and 52b were not insert-molded, and the resin 51a and the insert members 52a and There is also a method of curing and bonding 2b to integrate them.However, in the later integration method, the accuracy of the position of the insert members 52a and 52b is inevitably lower than that of the insert mold. Therefore, it cannot be applied to a mold member that requires high positional accuracy with little variation. In addition, productivity was high because of the need for post-processing.
他にも、 第 1 8図にあらわすように予め軟質材 6 3でインサート部材 6 2 a , 6 2 bを 1次モールドし、 次にその 1次モールド品をインサー ト部材として樹脂 6 1 aで 2次モールドするものがある。 しかし、 この 方法も多重成形であることから成形金型費及び成形費がコスト高になる 問題があった。  In addition, as shown in Fig. 18, insert members 62a and 62b are first molded in advance with soft material 63, and then the primary molded product is used as an insert member with resin 61a. There is a thing to do secondary molding. However, since this method is also a multiple molding method, there is a problem that the cost of a molding die and molding cost increases.
その他、 第 1 9図のように樹脂 7 1 a内にガスをモールド充填する途 中に注入口 7 3から注入し、 インサート部材 7 2 a, 7 2 bの周辺の一 部に空間部 7 4を形成させる方法がある。 しかし、 空間部 7 4の大きさ や位置は樹脂 7 1 aの粘度に非常に左右されるため、 流動的であり安定 した空間部 7 4を確実に所望するィンサート部材 7 2 a, 7 2 bの外周, 角部, 突起部, 段差部の近傍に設けることが難しかった。  In addition, as shown in Fig. 19, gas is injected from the injection port 73 while the resin 71a is being filled with the mold, and a space 74 is formed in a part of the periphery of the insert members 72a and 72b. Is formed. However, since the size and position of the space 74 are greatly affected by the viscosity of the resin 71a, the insert member 72a, 72b that is desirably a fluid and stable space 74 is desired. It was difficult to provide them near the outer periphery, corners, protrusions, and steps of the slab.
以上のような問題点を回避する手段として本発明を開発した。  The present invention has been developed as means for avoiding the above problems.
