押釦スイッチ用カバー部材11は通常、図２に示したように指を触れるキートッ プ部12と薄肉可動部13およびこれを保持するベース部14とから構成されており、 このキートップ部は指の押圧による伝達に好適な強度および硬度を有するものと され、これは角柱、円柱などの形状に成形されているが、これにはその下面に下 方に僅かに突出状に接点部15が形成されており、これらはその下面の周縁部が前 記ベース部と接合一体化され保持されているが、この柱状のキートップ部本体は 通常、高さが２〜８mm程度、多くのものは３〜７mm程度で径あるいは一辺が５〜 20mm程度の塊状部材とされ、その底面の接点部は径が底面より小さい２〜４mmで 、下方への突出高さが 0.5〜0.9mm のものが中央部に一体に成形されている。As shown in FIG. 2, the push button switch cover member 11 usually includes a key top portion 12 for touching with a finger, a thin movable portion 13 and a base portion 14 for holding the thin movable portion 13, and this key top portion is a It has a strength and hardness suitable for transmission by pressing, and it is formed in the shape of a prism, a cylinder, etc., on which the contact portion 15 is formed on the lower surface in a slightly protruding downward direction. These are held by joining the peripheral portion of the lower surface with the above-mentioned base portion integrally, but the column-shaped key top body usually has a height of about 2 to 8 mm, and most of them have a height of 3 to 3 mm. It is a lump member with a diameter of about 7 mm or one side of 5 to 20 mm, and the contact point on the bottom surface is 2 to 4 mm in diameter smaller than the bottom surface, and the one with a downward protrusion height of 0.5 to 0.9 mm is in the center part. It is molded integrally.
【０００３】 このような押釦スイッチ用カバー部材を製造するための金型は、図３に示され ているようにこのカバー部材の上面側と下面側の形状に対応する表面がそれぞれ 形成された二つの割り金型とされており、この製造はこの金型のキャビティに材 料を圧入することによって行なわれている。 この押釦スイッチ用カバー部材成形用金型21のキートップ部側形成用の上金型 22にはキートップ部に対応する深い凹部23が形成されており、これと組み合わさ れる接点部側形成用金型24には接点部の凸形状に対応する浅い凹部25などが形成 されると共に、キートップ部の下端面の周縁には比較的薄いベース部材が一体に 接合するようなキャビティが両金型間に形成されている。As shown in FIG. 3, a mold for manufacturing such a push button switch cover member has two surfaces each having a surface corresponding to the shape of the upper surface side and the lower surface side of the cover member. The mold is made of two split molds, and the manufacturing is performed by press-fitting the material into the cavity of the mold. A deep recess 23 corresponding to the key top portion is formed in the upper die 22 for forming the key top portion side of the push-button switch cover member forming die 21 , and the contact portion side forming die to be combined therewith is formed. The mold 24 is formed with a shallow recess 25 corresponding to the convex shape of the contact part, and a cavity that allows a relatively thin base member to be integrally joined is formed between the molds at the peripheral edge of the lower end surface of the key top part. Is formed in.
【０００４】 そして、この押釦スイッチ用カバー部材の製造は、シリコーンゴム、天然ゴム 、ＥＰＤＭやＮＢＲなどの未加硫ゴム材料を上記した接点部形成側金型とキート ップ部形用側金型とで形成される割型のキャビティ内で射出成形、トランスファ 成形、圧縮成形などの方法で成形するという成形方法で行なわれている。 しかし、このような割り金型による成形では、上記したようなカバー部材の形 状の特異性から、割り金型を開いたときに成形物が常にキートップ部側形成用の 金型に付着し、これを金型から引き離す操作に人手が要するし、場合によっては その型離れが悪いためにこれを引張ると強度的に弱い薄肉可動部などが破損する などの不都合が生ずる欠点がある。The push button switch cover member is manufactured by using the above-mentioned contact part forming side mold and key top part forming side mold made of unvulcanized rubber material such as silicone rubber, natural rubber, EPDM and NBR. It is performed by a molding method such as injection molding, transfer molding, and compression molding in a cavity of a split mold formed by. However, in molding with such a split mold, due to the peculiar shape of the cover member as described above, when the split mold is opened, the molded product always adheres to the mold for forming the key top portion side. However, there is a disadvantage in that it requires manpower to separate the mold from the mold, and in some cases, the mold separation is poor, so that pulling the mold may cause inconvenience such as damage to thin-walled movable parts, which are weak in strength.
【０００５】 そのため、このキートップ部側形成用金型からの型離れ不良を解消ないし軽減 する方法として、従来例えばつぎの４つの方法が適用されている。 界面活性材系、フッ素系等の離型剤をキートップ部側形成用の金型のみに塗 布するか、もしくは接点部側形成用の金型よりもキートップ部側形成用の金型に 多めに塗布することを一定成形ショット数間隔で行ないながら成形する。 キートップ部側形成用の金型表面には成形品が金型に粘着しにくいテフロン 系の鍍金を施し、接点部側形成用の金型表面には、テフロン系の鍍金よりも金型 に成形品が粘着しやすいクロム、もしくはニッケル系の鍍金処理した金型を用い て成形する。 押釦スイッチ用カバー部材の接点部に該当する位置の側面部の角度を接点部 底面に対して、50〜80°となるような金型を用いて成形する。 キートップ部側形成用の金型の表面粗度が接点部側形成用の金型の表面粗度 に比べ滑らかになるようにブラスト処理を行なった金型を用いて成形する。Therefore, for example, the following four methods have been conventionally applied as a method of eliminating or reducing the mold release defect from the key top portion side forming mold. Apply a release agent such as a surfactant or fluorine to only the mold for forming the key top side, or use a mold for forming the key top side rather than the mold for forming the contact side. Molding is performed while applying a large amount at a constant molding shot interval. The surface of the mold for forming the key top part is coated with Teflon-based plating, which makes it difficult for the molded product to stick to the mold, and the surface of the mold for forming contact points is molded with a mold that is more than Teflon-based plating. Mold the product using a chrome- or nickel-based metal mold that tends to stick to the product. A push button switch cover member is molded using a mold in which the angle of the side surface at a position corresponding to the contact portion is 50 to 80 ° with respect to the bottom surface of the contact portion. Molding is performed using a mold that has been blasted so that the surface roughness of the die for forming the key top portion side is smoother than the surface roughness of the die for forming the contact portion side.
【０００６】[0006]
しかし、この第一の方法には離型剤が成形品に付着してしまうために、後工程 で成形品を洗浄することが必要とされるという不利があり、この第二の方法には テフロン自体が極めて柔らかい素材で容易に磨滅するために、鍍金としての耐久 性がなく、したがって短期間に再鍍金しなおす必要があるという不要がある。 また、この第三の方法には接点部が成形品全体に均一に配置されている場合に は効果があるが、接点部が均一に配列されていない成形品では金型が開いた時に 成形品がキートップ部側形成用の金型の方に付着したり、金型が開いた瞬間に成 形品が破れたりする不利がある。 However, this first method has the disadvantage that the mold release agent adheres to the molded product, which requires cleaning of the molded product in a later step. There is no need for re-plating in a short period of time because it does not have the durability as a plating because it is easily worn away by a very soft material. In addition, this third method is effective when the contact parts are evenly arranged on the entire molded product, but for the molded product where the contact parts are not evenly arranged, the molded product is opened when the mold is opened. Is attached to the mold for forming the key top portion side, or the molded product is broken at the moment the mold is opened.
【０００７】 なお、この第四の方法には金型のキートップ部側形成用金型の掘り込み部と接 点部側形成用の金型の掘り込み部の表面積の比率が65以上：１になると、この方 法のみで成形品を接点部側形成用の金型のほうに付着させておくことが難しくな り、これはブラストの番手を＃60よりも粗くするとその金型を用いて成形された 押釦スイッチ用カバー部材の薄肉可動部のスプリング機能に問題が生じたり、加 工の再現性が保てなくなったりするため、安定に押釦スイッチ用カバー部材を製 造することができないという問題点がある。According to the fourth method, the ratio of the surface area of the dug portion of the die for forming the key top portion side of the die to the dug portion of the die for forming the contact portion side is 65 or more: 1 In this case, it becomes difficult to attach the molded product to the mold for forming the contact part side only by this method. This is because if the blast number is rougher than # 60, molding is performed using that mold. Problems with the spring function of the thin-walled movable part of the push button switch cover member that has been created, and inability to maintain reproducibility of processing, make it difficult to manufacture the push button switch cover member in a stable manner. There is.

本考案はこのような不利、問題点を解決した押釦スイッチ用カバー部材成形用 金型に関するものであり、これは押釦スイッチ用カバー部材のキートップ部側形 成用の金型の表面粗度が、接点部側形成用の金型の表面粗度に比べて滑らかであ り、かつ接点部側形成用の金型のうち押釦スイッチ用カバー部材の薄肉可動部を 形成する部位のみが接点部側形成用金型のその他の部分に比べて表面粗度が滑ら かであることを特徴とするものである。 The present invention relates to a mold for molding a cover member for a push button switch, which solves such disadvantages and problems, and it has a surface roughness of a mold for forming a key top portion side of a cover member for a push button switch. , The surface roughness of the mold for forming the contact part side is smoother, and only the part of the mold for forming the contact part side that forms the thin movable part of the cover for the push button switch is the contact part side. The feature is that the surface roughness is smoother than the other parts of the forming die.
【０００９】 すなわち、本考案者らは押釦スイッチ用カバー部材成形用金型の成形性改善方 法について種々検討した結果、この金型についてはキートップ部側形成用の金型 と接点部側形成用の金型の最大キーにおける凹部の表面積の比率に応じて表面粗 度を適宜変更すると共に、キートップ部側形成用の金型と接点部側形成用の金型 の最大キーにおける凹部の表面積の比率が65以上：１であった場合には、薄肉可 動部を形成する部位の金型表面のみを＃60〜＃100 のブラスト処理をを行ない、 その他の部位には＃60以下のブラスト処理を行った金型を用いると、金型を用い たときに成形品を必ず接点部側形成用の金型に密着させた状態とすることができ ることを見出して本考案を完成させた。 以下にこれをさらに詳述する。That is, as a result of various studies by the present inventors on a method for improving the moldability of a mold for molding a cover member for a push button switch, this mold was found to be a mold for forming a key top portion side and a mold for forming a contact portion side. The surface roughness of the recesses in the maximum key of the die for forming the key top side and the die for forming the contact point side is changed while changing the surface roughness appropriately according to the ratio of the surface area of the recesses in the maximum key of the die for forming If the ratio is 65: 1 or more, blasting # 60 to # 100 is performed only on the mold surface of the part that forms the thin movable part, and blasting # 60 or less is performed on the other parts. The inventors have completed the present invention by finding that the use of a treated mold makes it possible to keep the molded product in close contact with the mold for forming the contact portion side when the mold is used. . This will be described in more detail below.
【００１０】[0010]
本考案の押釦スイッチ用カバー部材成形用金型はキートップ部側成形用の金型 と接点部側形成用の金型とからなる割り型のものとされるが、これは前記したよ うに押釦スイッチ用カバー部材のキートップ部側形成用の金型の表面粗度が、接 点部側形成用の金型の表面粗度に比べて滑らかであり、かつ接点部側形成用の金 型のうち押釦スイッチ用カバー部材の薄肉可動部を形成する部位のみが接点部側 形成用金型のその他の部分に比べて表面粗度が滑らかであることを特徴とするも のであり、これによれば金型を開いたときに成形品が必ず接点部側形成用の金型 に密着した状態で得られ、成形品の離型も容易に行なうことができるという有利 性が与えられる。 The mold for molding the cover member for the push button switch of the present invention is a split mold composed of a mold for molding the key top portion side and a mold for forming the contact portion side, which is as described above. The surface roughness of the die for forming the key top portion side of the switch cover member is smoother than the surface roughness of the die for forming the contact portion side, and the surface roughness of the die for forming the contact portion side is Among them, only the portion of the cover member for the push button switch that forms the thin movable portion is characterized in that the surface roughness is smoother than the other portions of the mold for forming the contact portion side. When the mold is opened, the molded product is always obtained in a state of being in close contact with the mold for forming the contact portion side, which provides an advantage that the molded product can be easily released from the mold.
【００１１】 本発明は押釦スイッチ用カバー部材成形用金型に関するものであるが、この金 型１は図１に示したようにキートップ部側形成用上金型２と接点部側形成用下金 型３とからなり、この上金型２にはキートップ部に対応する凹部４が設けられて おり、この下金型には接点部に対応する浅い凹部５などが設けられている。 しかして、この金型では金型を開いたときに成形品が接点部側形成用金型の側 に密着した状態で得られるようにするために、接点部側形成用金型の表面６、薄 肉可動部の表面７の表面粗さをキートップ部側形成用金型のキートップ部天面形 成部８、側面形成部９の表面粗さよりも充分粗面としておくことが重要であるが 、薄肉可動部形成部位についてはその表面７の粗面粗さを滑らかにしておかない と、押圧荷重が不安定なものとなるのでこの部分のみを他の接点部側形成用金型 の表面６よりも滑らかにしておく必要がある。The present invention relates to a mold for molding a cover member for a push button switch. As shown in FIG. 1, this mold 1 includes an upper mold 2 for forming a key top portion side and a lower mold for forming a contact portion side. The upper mold 2 is provided with a recess 4 corresponding to the key top portion, and the lower mold is provided with a shallow recess 5 corresponding to the contact portion. Therefore, in order to obtain a molded product in close contact with the contact part side forming mold side when the mold is opened, the surface 6 of the contact part side forming mold, It is important that the surface roughness of the surface 7 of the thin-walled movable part is sufficiently rougher than the surface roughness of the top surface forming part 8 and the side surface forming part 9 of the key top part forming die. However, if the rough surface roughness of the surface 7 of the thin-walled movable part forming part is not smoothed, the pressing load will become unstable, so only this part will be the surface of the other contact part side forming mold. It should be smoother than 6.
【００１２】 この表面粗さの決定は成形品の最大のキーの掘り込み部分のキートップ部側形 成用金型の２の凹部表面積と、接点部側形成用金型３の凹部表面積の比率に応じ て決定すればよいが、これらの表面を粗面化するためにはけい砂、鋳鉄グリッド 、スチールグリッド、カットワイヤー、アルミナグリッド、炭化けい素グリッド 、スラググリッドなど（グリッドとは鮮鋭な綾角をもつ粒をいう）のブラスト材 を遠心式ブラスト装置、吸引式ブラスト装置、加圧式ブラスト装置などを用いて 金型にぶつけ粗面化すればよいが、これらのブラスト材はあらかじめ標準ふるい でサイズ毎に粒度を選別したものを用いることがよい。This surface roughness is determined by the ratio of the concave surface area of the key top portion side forming die 2 of the maximum key engraved portion of the molded product to the concave surface area of the contact portion side forming die 3. However, in order to roughen these surfaces, silica sand, cast iron grids, steel grids, cut wires, alumina grids, silicon carbide grids, slag grids, etc. The blasting material (of which there is an angled grain) can be roughened by hitting it with a centrifugal blasting device, suction blasting device, pressure blasting device, etc. It is preferable to use the one in which the grain size is selected for each size.
【００１３】 この接点部側形成用金型の粗面化は、例えば薄肉可動部を形成する部分のみを ＃60のブラスト材で処理し、その他の部分を＃30または＃40のブラスト材で処理 すればよいが、これには最初に接点部側形成用金型の全面を＃60のブラスト材で 処理したのち、薄肉可動部を形成する部分だけをゴムなどの弾性材料でマスキン グし、ついで＃30また＃40のブラスト材で処理するようにすればよい。 なお、本考案の押釦スイッチ用カバー部材成形用金型により押釦スイッチ用カ バー部材を成形するときの最大キーにおけるキートップ部形成用掘り込み部と接 点部形成用掘り込み部の凹部の表面積とブラスト材のサイズについては表１に示 したものが例示される。The roughening of the mold for forming the contact portion side is performed by, for example, treating only the portion forming the thin-walled movable portion with the # 60 blast material and treating the other portions with the # 30 or # 40 blast material. This can be done by first treating the entire surface of the mold for forming the contact side with # 60 blasting material, and then masturbating only the part that forms the thin wall moving part with an elastic material such as rubber. It should be treated with # 30 or # 40 blast material. When the cover member for a push button switch of the present invention is used to mold a cover member for a push button switch, the surface area of the recessed portion of the key top portion forming digging portion and the contact portion forming digging portion in the maximum key is formed. As for the size of the blast material, those shown in Table 1 are exemplified.

つぎに本考案の実施例をあげる。 実施例 キートップ部側形成用、接点部側形成用の両金型の両面にクロムメッキを施し た、最大キーにおけるキートップ部形成用の掘り込み部表面積が3,000cm2、接点 部形成用の掘り込み部表面積が25cm3 である押釦スイッチ用カバー部材成形用金 型に、鋳鉄グリッドをブラスト材として吸引式ブラスト装置を用いて、そのキー トップ部側形成用金型の内面を＃100 のブラスト材でブラスト処理すると共に、 接点部側形成用金型の薄肉可動部を＃60のブラスト材で、またその他の部分を＃ 30のブラスト材でブラスト処理した。Next, examples of the present invention will be given. Example Both sides of both dies for forming the key top part side and contact part side are plated with chrome.The surface area of the dug part for forming the key top part of the maximum key is 3,000 cm 2 , and for the contact part formation Using a suction type blasting machine with a cast iron grid as the blasting material for a mold for molding a cover member for a push button switch with a surface area of the dug portion of 25 cm 3 , the inner surface of the molding die for the key top part is blasted with # 100. In addition to the blasting with the material, the thin-walled movable part of the contact-side forming die was blasted with # 60 blasting material, and the other parts were blasted with # 30 blasting material.
【００１６】 ついで、この金型を用いて押釦スイッチ用カバー部材を 1,000ショット成形し たところ、いずれの場合も成形品は接点部側形成用金型に付着しており、これら の成形品はその薄肉可動部がすべて押釦スイッチの機能を失っておらず、高品質 のものであった。Next, when a push button switch cover member was molded for 1,000 shots using this mold, the molded product adhered to the contact side forming mold in all cases, and these molded products All the thin movable parts did not lose the function of the push button switch and were of high quality.

本考案は押釦スイッチ用カバー部材成形用金型に関するものであり、これは前 記したように押釦スイッチ用カバー部材のキートップ部側形成用の金型の表面粗 度が、接点部側形成用の金型の表面粗度に比べて滑らかであり、かつ接点部側形 成用の金型のうち薄肉可動部を形成する部位のみが接点部側形成用金型の他の部 分に比べて表面粗度が滑らかであることを特徴とするものであるが、このような 金型を使用して押釦スイッチ用カバー部材を成形すると金型を開いたときに成形 品を必ず接点部側形成用の金型に密着して得ることができ、成形品の離型も容易 に行なうことができるし、このものは薄肉可動部による押釦スイッチの機能に問 題の生ずることがなくなるという有利性が与えられる。 The present invention relates to a mold for molding a cover member for a push button switch, which has a surface roughness of a mold for forming a key top portion of a cover member for a push button switch as described above. Compared to the other parts of the contact part side forming mold, only the part that forms the thin-walled movable part is smoother than the surface roughness of the contact part side forming mold and the contact part side forming mold. The feature is that the surface roughness is smooth, but if a mold is used to mold a cover member for a pushbutton switch, the molded product must be used for forming the contact side when the mold is opened. Can be obtained in close contact with the mold, and the molded product can be easily released from the mold. This has the advantage that the function of the push button switch due to the thin-walled moving part does not cause any problems. To be
