図１〜図４は本発明の第１実施の形態に係るインサート成形部品１０についての説明図である。図１は本発明の第１の実施の形態に係るインサート成形部品１０を示す平面図、図２はインサート成形部品１０を示す縦断面図、図３はインサート成形部品１０の製造工程を示す縦断面図、図４はインサート成形部品１０の製造工程を示す縦断面図である。 1 to 4 are explanatory views of the insert molded part 10 according to the first embodiment of the present invention. FIG. 1 is a plan view showing an insert molded part 10 according to the first embodiment of the present invention, FIG. 2 is a vertical sectional view showing the insert molded part 10, and FIG. 3 is a vertical cross section showing a manufacturing process of the insert molded part 10. FIG. 4 is a vertical sectional view showing a manufacturing process of the insert molded part 10.
図１及び図２に示すように、インサート成形部品１０は、アクリル系エラストマ等の樹脂材製の一次成形部２０と、シリコン系エラストマ等の樹脂材製の二次成形部３０とが積層して形成されている。一次成形部２０には、ベース部２１が設けられている。このベース部２１には、二段（多段）に形成された凹部２２（下段）及び凹部２３（上段）が設けられている。凹部２２には、リチウムイオン電池（インサート部品）４０が実装され、凹部２３には厚さ０．３〜１ｍｍ程度のオレフィンシート材製の断熱部品５０が配置されている。断熱部品５０は平板状のベース部５１を有している。リチウムイオン電池４０の動作保証温度は６０℃であり、６０℃以下に維持することが好ましい。また、二次成形部３０を形成するシリコン系エラストマは成形時の温度が１５０℃程度である。 As shown in FIGS. 1 and 2, in the insert molded part 10, a primary molding portion 20 made of a resin material such as an acrylic elastomer and a secondary molding portion 30 made of a resin material such as a silicon elastomer are laminated. It is formed. The primary forming portion 20 is provided with a base portion 21. The base portion 21 is provided with a recess 22 (lower stage) and a recess 23 (upper stage) formed in two stages (multi-stage). A lithium ion battery (insert component) 40 is mounted in the recess 22, and a heat insulating component 50 made of an olefin sheet material having a thickness of about 0.3 to 1 mm is arranged in the recess 23. The heat insulating component 50 has a flat plate-shaped base portion 51. The guaranteed operating temperature of the lithium ion battery 40 is 60 ° C., and it is preferable to maintain the temperature at 60 ° C. or lower. Further, the temperature of the silicon-based elastomer forming the secondary molding portion 30 at the time of molding is about 150 ° C.
このように構成されたインサート成形部品１０は、次のようにして形成される。すなわち、最初に一次成形部２０を射出成形する。次に、図３に示すように、ベース部２１の形成後に切削等によって凹部２２，２３を形成する。次に、図４に示すように、凹部２２にリチウムイオン電池４０を実装し、その上に断熱部品５０を載置する。この際、接着等によって断熱部品５０とリチウムイオン電池４０を接合する。断熱部品５０は凹部２３内に収まるように配置する。 The insert molded part 10 configured in this way is formed as follows. That is, first, the primary molding unit 20 is injection-molded. Next, as shown in FIG. 3, the recesses 22 and 23 are formed by cutting or the like after the base portion 21 is formed. Next, as shown in FIG. 4, the lithium ion battery 40 is mounted in the recess 22, and the heat insulating component 50 is placed on the lithium ion battery 40. At this time, the heat insulating component 50 and the lithium ion battery 40 are joined by adhesion or the like. The heat insulating component 50 is arranged so as to fit in the recess 23.
次に、一次成形部２０の上部に金型を設置し、二次成形を行って二次成形部３０を形成する。二次成形部３０は板状のベース部３１から形成されている。また、図４中Ｒは樹脂の流動方向を示している。この時、二次成形部３０の材料であるシリコン系エラストマは１９０℃前後に熱せられている。このため、一次成形部２０の断熱部品５０の上面は高温に加熱されるが、断熱部品５０の断熱性によってリチウムイオン電池４０は６０℃以上には加熱されない。このため、リチウムイオン電池４０の動作保証温度を超えることがない。また、圧力についても断熱部品５０によって遮断される。なお、断熱部品５０は樹脂の圧力によって移動することが無いように抑え部品等によって押圧することが望ましい。 Next, a mold is installed on the upper portion of the primary molding portion 20, and secondary molding is performed to form the secondary molding portion 30. The secondary molding portion 30 is formed from a plate-shaped base portion 31. Further, R in FIG. 4 indicates the flow direction of the resin. At this time, the silicon-based elastomer, which is the material of the secondary molding unit 30, is heated to around 190 ° C. Therefore, the upper surface of the heat insulating component 50 of the primary molding portion 20 is heated to a high temperature, but the lithium ion battery 40 is not heated to 60 ° C. or higher due to the heat insulating property of the heat insulating component 50. Therefore, the operation guaranteed temperature of the lithium ion battery 40 is not exceeded. The pressure is also cut off by the heat insulating component 50. It is desirable that the heat insulating component 50 is pressed by a holding component or the like so as not to move due to the pressure of the resin.
また、成形時や成形後にリチウムイオン電池４０に不具合が生じ、封止できなくなり、内部溶液が漏れた場合であっても、断熱部品５０がリチウムイオン電池４０の面積より広く配置されているため、断熱部品５０の外周を回り込まなければベース部３１に達しないため、安全性を確保することができる。 Further, even if the lithium ion battery 40 becomes defective during or after molding and cannot be sealed and the internal solution leaks, the heat insulating component 50 is arranged wider than the area of the lithium ion battery 40. Since the base portion 31 is not reached unless it goes around the outer periphery of the heat insulating component 50, safety can be ensured.
なお、断熱部品５０については、二次成形部３０の熱量を基に熱容量を計算して材料及び厚さを選ぶことが望ましい。また、断熱部品５０が一次成形部２０のベース部３１より上に突出すると二次成形部３０の樹脂が入り込みやすくなるので、突出しない寸法とする。 For the heat insulating component 50, it is desirable to calculate the heat capacity based on the amount of heat of the secondary molded portion 30 and select the material and thickness. Further, when the heat insulating component 50 protrudes above the base portion 31 of the primary molding portion 20, the resin of the secondary molding portion 30 easily enters, so the dimensions are set so as not to protrude.
このように本実施の形態に係るインサート成形方法によるインサート成形部品１０は、二次成形部３０の成形に際して、リチウムイオン電池４０を過度に温度上昇させることがなく、また高圧による影響を受けないため、特性劣化や破壊が起きることを防止できる。このため、リチウムイオン電池４０のインサート成形を実現することができ、腕時計バンドやウェアラブル電子機器への適用が可能となる。 As described above, the insert molded part 10 by the insert molding method according to the present embodiment does not excessively raise the temperature of the lithium ion battery 40 when molding the secondary molding portion 30, and is not affected by the high pressure. , It is possible to prevent characteristic deterioration and destruction. Therefore, insert molding of the lithium ion battery 40 can be realized, and it can be applied to a wristwatch band and a wearable electronic device.
図５は本発明の第２の実施の形態に係るインサート成形部品１０Ａを示す縦断面図である。図５において図１〜図４と同一機能部分には同一符号を付し、その詳細な説明は省略する。 FIG. 5 is a vertical cross-sectional view showing the insert molded part 10A according to the second embodiment of the present invention. In FIG. 5, the same functional parts as those in FIGS. 1 to 4 are designated by the same reference numerals, and detailed description thereof will be omitted.
インサート成形部品１０Ａは、凹部２３の代わりに凹部２４が設けられている。凹部２４の二次成形部の成形時の流動方向Ｒに沿った下流側の壁面の位置は、凹部２４の開口部から底部側にかけて下流側に傾いている。凹部２４には断熱部品５０Ａが挿入されている。 The insert molded part 10A is provided with a recess 24 instead of the recess 23. The position of the wall surface on the downstream side along the flow direction R of the secondary molding portion of the recess 24 during molding is inclined to the downstream side from the opening of the recess 24 to the bottom side. A heat insulating component 50A is inserted in the recess 24.
このように構成されていると、上述したインサート成形方法によるインサート成形部品１０と同様の効果を有すると共に、樹脂の流動によって断熱部品５０Ａに圧力が加わっても、断熱部品５０Ａは凹部２４の内部に食い込む方向に力が加わるため、断熱部品５０Ａが脱落しにくいという効果がある。 With this configuration, it has the same effect as the insert molded part 10 by the insert molding method described above, and even if pressure is applied to the heat insulating part 50A due to the flow of the resin, the heat insulating part 50A is inside the recess 24. Since the force is applied in the biting direction, there is an effect that the heat insulating component 50A is hard to fall off.
図６は本発明の第３の実施の形態に係るインサート成形部品１０Ｂを示す縦断面図である。図６において図１〜図４と同一機能部分には同一符号を付し、その詳細な説明は省略する。 FIG. 6 is a vertical cross-sectional view showing the insert molded part 10B according to the third embodiment of the present invention. In FIG. 6, the same functional parts as those in FIGS. 1 to 4 are designated by the same reference numerals, and detailed description thereof will be omitted.
インサート成形部品１０Ｂにおいては、凹部２３の代わりに凹部２５が設けられている。凹部２５の外周には溝が設けられており、複雑な外郭を有している。この凹部２５には断熱部品５０Ｂが配置されている。断熱部品５０Ｂのベース部５１から下部に突出した突出部５３が設けられている。凹部２５の溝部には突出部５３が挿入される。 In the insert molded part 10B, the recess 25 is provided instead of the recess 23. A groove is provided on the outer periphery of the recess 25, and has a complicated outer shell. A heat insulating component 50B is arranged in the recess 25. A protruding portion 53 projecting downward from the base portion 51 of the heat insulating component 50B is provided. The protrusion 53 is inserted into the groove of the recess 25.
このように構成されていると、上述したインサート成形方法によるインサート成形部品１０と同様の効果を有すると共に、リチウムイオン電池４０の内部溶液が漏れた場合であっても、複雑な形状の凹部２４の外側を回り込む必要があるため、ベース部３１に達することを防止し、安全性を確保することができる。 With this configuration, it has the same effect as the insert-molded part 10 by the insert-molding method described above, and even if the internal solution of the lithium-ion battery 40 leaks, the recess 24 having a complicated shape Since it is necessary to go around the outside, it is possible to prevent the base portion 31 from reaching the base portion 31 and ensure safety.
図７は本発明の第４の実施の形態に係るインサート成形部品１０Ｃを示す縦断面図である。図７において図１〜図４と同一機能部分には同一符号を付し、その詳細な説明は省略する。 FIG. 7 is a vertical cross-sectional view showing the insert molded part 10C according to the fourth embodiment of the present invention. In FIG. 7, the same functional parts as those in FIGS. 1 to 4 are designated by the same reference numerals, and detailed description thereof will be omitted.
インサート成形部品１０Ｃにおいては、凹部２３の代わりに凹部２６，２７，２８が設けられている。凹部２６には断熱部品５０Ｃが配置され、凹部２７には金属材等の伝熱部品６０が配置され、凹部２８には断熱部品５０Ｄが配置されている。凹部２２，２６に比べて、凹部２７，２８の内径が大きく形成されている。すなわち、伝熱部品６０が断熱部品５０Ｃより外側に張り出して形成されている。 In the insert molded part 10C, recesses 26, 27, 28 are provided instead of the recess 23. A heat insulating component 50C is arranged in the recess 26, a heat transfer component 60 such as a metal material is arranged in the recess 27, and a heat insulating component 50D is arranged in the recess 28. The inner diameters of the recesses 27 and 28 are formed larger than those of the recesses 22 and 26. That is, the heat transfer component 60 is formed so as to project outward from the heat insulating component 50C.
このように構成されていると、上述したインサート成形方法によるインサート成形部品１０と同様の効果を有する。さらに、二次成形部３０を形成する樹脂からの熱が断熱部品５０Ｄからリチウムイオン電池４０側に伝わった場合に、伝熱部品６０からベース部２１側に熱を逃がすことができ、リチウムイオン電池４０に伝わる熱量を軽減することができる。 When configured in this way, it has the same effect as the insert molded part 10 by the above-mentioned insert molding method. Further, when the heat from the resin forming the secondary molding portion 30 is transferred from the heat insulating component 50D to the lithium ion battery 40 side, the heat can be released from the heat transfer component 60 to the base portion 21 side, and the lithium ion battery The amount of heat transferred to 40 can be reduced.
図８〜図１０は本発明の第５の実施の形態に係るインサート成形部品１０Ｄの製造工程を示す縦断面図である。これらの図において図１〜図４と同一機能部分には同一符号を付し、その詳細な説明は省略する。 8 to 10 are vertical cross-sectional views showing a manufacturing process of the insert molded part 10D according to the fifth embodiment of the present invention. In these figures, the same functional parts as those in FIGS. 1 to 4 are designated by the same reference numerals, and detailed description thereof will be omitted.
図８に示すように、インサート成形部品１０Ｄにおいては、断熱部品５０の代わりに断熱部品７０を用いている。断熱部品７０は、凹部２３に挿入されるベース部７１と、このベース部７１から二次成形部３０側に突出形成された突出形成部７２を備えている。さらに突出形成部７２から樹脂の流動方向Ｒに平行な向きに形成された鍔部７３が設けられている。 As shown in FIG. 8, in the insert molded part 10D, the heat insulating part 70 is used instead of the heat insulating part 50. The heat insulating component 70 includes a base portion 71 that is inserted into the recess 23, and a protrusion forming portion 72 that is formed so as to protrude from the base portion 71 toward the secondary molding portion 30. Further, a flange portion 73 formed from the protrusion forming portion 72 in a direction parallel to the flow direction R of the resin is provided.
このような断熱部品７０を用いた場合には、図９に示すように、追加の金型（抑え部材）８０によって断熱部品７０が樹脂によって移動することを防止した上で、二次成形部３０のための射出成形を行う。金型８０を取り出した後は、図１０に示すような構造を有するインサート成形部品１０Ｄが形成される。 When such a heat insulating component 70 is used, as shown in FIG. 9, an additional mold (holding member) 80 prevents the heat insulating component 70 from moving due to the resin, and then the secondary molding portion 30. Perform injection molding for. After the mold 80 is taken out, the insert molded part 10D having the structure as shown in FIG. 10 is formed.
このように構成されていると、上述したインサート成形方法によるインサート成形部品１０と同様の効果を有する。また、ベース部７１に触れる樹脂の量を減らすことで、リチウムイオン電池４０へ影響する熱量を軽減することができる。さらに、断熱部品７０が一次成形部２０に加えて、二次成形部３０内にも封止されることから、成形後の強度が大きくなるという効果がある。 When configured in this way, it has the same effect as the insert molded part 10 by the above-mentioned insert molding method. Further, by reducing the amount of resin that comes into contact with the base portion 71, the amount of heat that affects the lithium ion battery 40 can be reduced. Further, since the heat insulating component 70 is sealed in the secondary molding portion 30 in addition to the primary molding portion 20, there is an effect that the strength after molding is increased.
なお、本発明は前記実施の形態に限定されるものではない。例えば、上述した例では、インサート成形部品としてリチウムイオン電池を例示したが、熱に弱いデバイスとして有機ＥＬや、異方性導電膜によって接合した電子製品等であっても、同様に適用できるのは勿論である。この他、本発明の要旨を逸脱しない範囲で種々変形実施可能であるのは勿論である。 The present invention is not limited to the above embodiment. For example, in the above-mentioned example, a lithium ion battery is exemplified as an insert molded part, but it can be similarly applied to an organic EL as a heat-sensitive device, an electronic product bonded by an anisotropic conductive film, or the like. Of course. In addition, it goes without saying that various modifications can be carried out without departing from the gist of the present invention.
