【産業上の利用分野】[Industrial applications]

射出成形品を成形後金型から外すことなく加熱溶着して中空品を製作する中空 品成形装置に関する。 The present invention relates to a hollow article molding apparatus for producing a hollow article by heating and welding an injection-molded article without removing it from a mold.

【0002】[0002]

【従来の技術】[Prior art]

射出成形機で目的の中空品を構成する一組のパーツ部品を成形し、各々を可動 型と固定型に残して型開する。金型をスライドさせることにより両パーツ同士を 中空状に組合せ、合わせ目の周囲に再度樹脂を射出してハチ巻状成形により接合 する。 An injection molding machine is used to mold a set of parts that make up the desired hollow product, and the molds are opened leaving the movable and fixed molds. By sliding the mold, both parts are combined into a hollow shape, and the resin is injected again around the joints and joined by bee winding molding.

【0003】 更に詳しく図によって説明する。図10は中空品成形金型43を射出成形機4 1に取り付けたところを示す。可動盤21と固定盤20の間に該中空品成形金型 43を取り付けてある。射出装置42の加熱装置22内に溶融樹脂を可塑化蓄積 し、ノズル23を介して射出することができる。Further details will be described with reference to the drawings. FIG. 10 shows the hollow article molding die 43 attached to the injection molding machine 41. The hollow product molding die 43 is attached between the movable platen 21 and the fixed platen 20. The molten resin can be plasticized and accumulated in the heating device 22 of the injection device 42 and injected through the nozzle 23.

【0004】 図11(1)に於いて説明すると、固定型18は移動可能のキャビティ面を持 つスライド金型47とベース48より成り、L型ブラケット56に取り付けたシ リンダ44により移動可能となっている。スライド金型47には第一のスプルー 45と第二のスプルー46の通路が穿設されている。またパーティング面24よ り可動盤21側が可動型19を構成している。そしてパーティング面24には一 組のキャビティ49,50形成してある。To explain with reference to FIG. 11 (1), the fixed mold 18 is composed of a slide mold 47 having a movable cavity surface and a base 48, and is movable by a cylinder 44 attached to an L-shaped bracket 56. Has become. The slide mold 47 is provided with passages for a first sprue 45 and a second sprue 46. The movable plate 21 side of the parting surface 24 constitutes the movable mold 19. A pair of cavities 49 and 50 are formed on the parting surface 24.

【0005】 更に順を追って説明すると、図11(1)では可動盤21を固定盤20側に移 動させて中空品成形金型43を閉鎖圧締すると共に、加熱装置22のノズル23 をベース48のスプルーブッシュに押し付けて、射出の出来る状態にする。To explain further step by step, in FIG. 11 (1), the movable platen 21 is moved to the fixed platen 20 side to close and clamp the hollow product molding die 43, and the nozzle 23 of the heating device 22 is used as a base. Press it against the sprue bush of 48 and make it ready for injection.

【0006】 図11(2)は樹脂を射出充填したところを示す。樹脂は第一のスプルー45 の通路を通りキャビティ49,50内に充填されている。FIG. 11 (2) shows a state where resin is injected and filled. The resin is filled in the cavities 49 and 50 through the passage of the first sprue 45.

【0007】 図12(3)可動型19を開いて不要となった第一のスプルー51を落とした ところを示す。可動型19にはキャビティ49の成形品が、固定型18にはキャ ビティ50の成形品が保持されている。FIG. 12C shows a state where the movable mold 19 is opened and the unnecessary first sprue 51 is dropped. The movable mold 19 holds the molded product of the cavity 49, and the fixed mold 18 holds the molded product of the cavity 50.

【0008】 図12(4)ではシリンダ44を短縮させてスライド金型47を移動させ、キ ャビティ50を可動型19のキャビティ49と対向させる。In FIG. 12 (4), the cylinder 44 is shortened and the slide mold 47 is moved so that the cavity 50 faces the cavity 49 of the movable mold 19.

【0009】 図13(5)では再び可動型19を閉鎖して、キャビティ49,50の成形品 を中空状に組み合わせる。該成形品には予め個々の接続部外周に逃がし52,5 2が設けてあり、組み合わせた際にリング状の窪み53となる。再び加熱装置2 2のノズル23を固定型18に接触させ射出を行うと、樹脂は第二のスプルー4 6の通路を通り、上記のリング状の窪み53を埋めてキャビティ49,50の成 形品を接続し、中空品54となる。In FIG. 13 (5), the movable mold 19 is closed again, and the molded products of the cavities 49 and 50 are assembled into a hollow shape. The molded product is provided with reliefs 52 and 52 on the outer periphery of each connection portion in advance, and when combined, it becomes a ring-shaped recess 53. When the nozzle 23 of the heating device 22 is again brought into contact with the fixed mold 18 and injection is performed, the resin passes through the passage of the second sprue 46, fills the ring-shaped recess 53, and forms the cavities 49, 50. The products are connected to form a hollow product 54.

【0010】 図13(6)に於いて、可動型19を開き中空品54と第二のスプルー55を 落とす。こうして中空品54が完成する。In FIG. 13 (6), the movable die 19 is opened and the hollow article 54 and the second sprue 55 are dropped. In this way, the hollow product 54 is completed.

【0011】[0011]

【考案が解決しようとする課題】[Problems to be solved by the device]

従来方法で製作した中空品54は始めの射出行程で成形した成形品同士を中空 状に保持しておき、次の射出行程で射出した樹脂により該成形品同士を接続する 過程をとるため、後行程で射出した樹脂は接着するが最初の樹脂同士の接触面に は樹脂が侵入することが出来ず、この部分は隙間の狭いポケットを構成する。こ の中空品を容器として使用する際にはこのポケットへ内容物が侵入し問題を起こ すことがある。 In the hollow product 54 manufactured by the conventional method, the molded products formed in the first injection process are held in a hollow shape, and the molded products are connected by the resin injected in the next injection process. The resin injected in the process adheres, but the resin cannot penetrate into the first contact surface between the resins, and this part forms a pocket with a narrow gap. When this hollow product is used as a container, the contents may enter this pocket and cause a problem.

【0012】 その上二度目の射出で接続するため樹脂を盛り上げる空間を必要とし、デザイ ン上、機構上不便なことがある。このような課題を解決するためにシンプルで、 場所を取らずデザイン上も目立たない接続法を考案する必要があった。Moreover, since the connection is made by the second injection, a space for raising the resin is required, which may be inconvenient in terms of design and mechanism. In order to solve such a problem, it was necessary to devise a simple, space-saving connection method that is inconspicuous in terms of design.

【0013】[0013]

【課題を解決するための手段】[Means for Solving the Problems]

射出成形した中空品のパーツ部品を成形後可動型と固定型に別々に保持させ、 一方の金型をスライドして成形品を対向させ、その中間に熱板を挿入する。可動 型を熱板に押し付けると熱板は押されて固定型寄りに移動し、両方の成形品は熱 板を挟んで押しつけられることになる。この状態で熱板により成形品を加熱溶融 する。溶融後熱板を退避させ、可動型を更に閉鎖し成形品同士を押し付けると容 着して中空品が出来上がる。金型のスライドと熱板の移動のシリンダを同一機構 内に組込んで、一行程で中空品を製造する中空品成形装置とする。 After molding, the hollow molded parts are held separately in the movable mold and the fixed mold, one mold is slid to face the molded product, and the hot plate is inserted in the middle. When the movable die is pressed against the hot plate, the hot plate is pushed and moves toward the fixed die, and both molded products are pressed with the hot plate sandwiched. In this state, the hot plate heats and melts the molded product. After melting, the hot plate is evacuated, the movable mold is further closed, and the molded products are pressed together to create a hollow product. By incorporating the slide of the mold and the cylinder for moving the hot plate into the same mechanism, it will be a hollow product molding device that manufactures hollow products in one stroke.

【0014】[0014]

【作用】[Action]

中空品のパーツ部品に熱板を押しつけて加熱溶融し、中空状に直接容着するの で所謂ポケットは発生しない。また容着部の所要体積は最小済む。その上デザイ ン上の自由度が増す。 Since a hot plate is pressed against a hollow part part to heat and melt it and directly adhere to the hollow part, so-called pockets do not occur. Moreover, the required volume of the attachment portion is minimized. Moreover, the degree of freedom in design is increased.

【実施例】【Example】

図9に本考案の中空品成形装置(以後成形装置と記す)の外観図を示す。そし て従来技術と同一の名称で、同じ使用目的の部品は同一の番号を使用する。可動 側のキャビティ面がスライド構造である可動型19と固定型18のパーティング 面には一組の中空品構成要素であるパーツ部品のキャビティ14,15が設けら れている。シリンダ11により可動型19のキャビティ面がスライドできる構造 になっていて、該シリンダ11を伸長すると該可動型19のキャビティ15が固 定型18のキャビティ14と対向する位置に移動する。 FIG. 9 shows an external view of the hollow article molding apparatus of the present invention (hereinafter referred to as a molding apparatus). Then, the parts having the same names and the same purposes as the prior art use the same numbers. On the parting surfaces of the movable die 19 and the stationary die 18 whose movable cavity surface is a slide structure, a pair of cavities 14 and 15 of part parts which are hollow component elements are provided. The cylinder 11 has a structure in which the cavity surface of the movable die 19 can be slid. When the cylinder 11 is extended, the cavity 15 of the movable die 19 moves to a position facing the cavity 14 of the fixed die 18.

【0016】 また固定型18上側に設けたシリンダ10には、シリンダロッドの先端にL型 の金具を取り付け、その先端には内部にカートリッジヒータ16を組込んだ熱板 13が接続してある。この熱板は成形した中空品のパーツ部品の接合部を加熱溶 融するためのものであり、シリンダ10を短縮すると熱板13はキャビティ14 の位置に移動し、キャビティ部に保持されたパーツ部品(以後成形品と記す)を 加熱溶融する。該熱板13はその表面をテフロン樹脂等でコーティングあるので 、成形品に接触して加熱溶融するも樹脂の粘着は無い。可動型19においては台 盤接触面にはエジェクタピン用孔12が設けてある。このエジェクタピン用孔1 2からピンを挿入して、中空品の突き出しができる。An L-shaped metal fitting is attached to the tip of a cylinder rod of the cylinder 10 provided on the upper side of the fixed die 18, and a hot plate 13 having a cartridge heater 16 incorporated therein is connected to the tip thereof. This hot plate is for heating and melting the joint part of the molded hollow part parts, and when the cylinder 10 is shortened, the hot plate 13 moves to the position of the cavity 14 and the part parts held in the cavity part. (Hereinafter referred to as a molded product) is melted by heating. Since the surface of the hot plate 13 is coated with Teflon resin or the like, there is no sticking of the resin even when the hot plate 13 is heated and melted by contacting the molded product. In the movable mold 19, the ejector pin hole 12 is provided on the base contact surface. A hollow product can be ejected by inserting a pin from the ejector pin hole 12.

【0017】 図1〜図8において本考案の成形装置を使って中空品を作る過程を順を追って 示してある。該成形装置は横型の射出成形機に取り付けて使用する。従って可動 金型は横方向に開閉して使用するが図では記載の都合上横向きに記載し、上下に 移動するような図になっている。それにシリンダ10は本来紙面に垂直に立設さ れているところ説明のため右側面に記入してある。1 to 8 show a process of making a hollow product using the molding apparatus of the present invention in order. The molding apparatus is attached to a horizontal injection molding machine for use. Therefore, the movable mold is used by opening and closing it in the lateral direction, but the drawing is shown in the lateral direction for convenience of description, and the drawing is such that it moves up and down. In addition, the cylinder 10 is originally set upright on the paper surface, and is shown on the right side surface for explanation.

【0018】 該成形装置は射出成形機の可動盤21と固定盤20の間に取り付けて開閉をす る。パーティング面24には製品キャビティ14,15が設けられている。該パ ーティング面24を境に可動盤21側は可動金型19であり、固定盤20側は固 定金型18となっている。固定金型18内部にホットランナ用のスプルーブッシ ュと一体構造のマニホールド25が内蔵され、ランナ26内の樹脂を常に溶融状 態に保つている。またランナ26からキャビティ14,15に通ずるゲート40 は射出時以外は通路を閉鎖出来る機構を備えている。The molding apparatus is mounted between the movable platen 21 and the fixed platen 20 of the injection molding machine to open and close. Product cavities 14 and 15 are provided on the parting surface 24. The movable plate 21 side is a movable mold 19 and the fixed plate 20 side is a fixed mold 18 with the parting surface 24 as a boundary. A fixed mold 18 has a built-in manifold 25 integrated with a sprue bush for the hot runner, and always keeps the resin in the runner 26 in a molten state. Further, the gate 40 communicating from the runner 26 to the cavities 14 and 15 is provided with a mechanism capable of closing the passage except at the time of injection.

【0019】 固定型18の側面にはシリンダ10が設置されており、ピストンロッド先端に L型金具を取り付け、その先はピン構造のジョイントに保持されたバー27を経 て熱板13が支持されている。シリンダ10が伸長した状態で熱板13は退避し た位置にあり、可動型19を開いてシリンダ10を短縮すると熱板13はキャビ ティ14の位置に来る。またバー27はピン構造のジョイント28に保持されて いるため熱板13に横方向からの力が働いた場合、僅かの移動が許容されている 。The cylinder 10 is installed on the side surface of the fixed die 18, an L-shaped metal fitting is attached to the tip of the piston rod, and the tip of the cylinder 10 is supported via a bar 27 held by a pin structure joint. ing. The hot plate 13 is in the retracted position with the cylinder 10 extended, and when the movable die 19 is opened to shorten the cylinder 10, the hot plate 13 comes to the position of the cavity 14. Further, since the bar 27 is held by a joint 28 having a pin structure, a slight movement is allowed when a lateral force is applied to the hot plate 13.

【0020】 可動型19はキャビティ面を構成するスライドブロック32とエジェクタピン 34を収納するスペーサブロック31より構成される。それぞれの各ブロックの 境界面はライナー29,30で保護されており、ライナー29,30はスライド する際の摺動面となる。スペーサブロック31に取り付けたシリンダ11のピス トンロッドはL型金具を介してスライドブロック32に固定されている。図3の 様に可動型19を開いてからシリンダ11を伸長させるとスライドブロック32 は移動してキャビティ15の位置はキャビティ14の位置と対向する。The movable die 19 is composed of a slide block 32 forming a cavity surface and a spacer block 31 accommodating an ejector pin 34. The boundary surface of each block is protected by liners 29 and 30, and the liners 29 and 30 serve as sliding surfaces when sliding. The piston rod of the cylinder 11 attached to the spacer block 31 is fixed to the slide block 32 via an L-shaped metal fitting. As shown in FIG. 3, when the movable die 19 is opened and the cylinder 11 is extended, the slide block 32 moves and the position of the cavity 15 faces the position of the cavity 14.

【0021】 可動型19のキャビティ15には、エジェクタピン56がコイルばね28に後 退方向に付勢されてその先端はキャビティ15に面した位置となるように保持さ れている。またスペーサブロック31にはエジェクタプレート35に保持された エジェクタピン34がコイルばね33により後退方向に付勢されて保持されてい る。In the cavity 15 of the movable die 19, the ejector pin 56 is biased by the coil spring 28 in the backward and backward direction, and the tip of the ejector pin 56 is held in a position facing the cavity 15. Further, the ejector pin 34 held by the ejector plate 35 is held in the spacer block 31 by being biased in the backward direction by the coil spring 33.

【0022】 次に作動の説明に移る。図1は成形装置を閉鎖して固定型18のスプルーブッ シュに加熱装置22のノズル23を押し付けて樹脂を射出して成形を行ったとこ ろを示す。ノズル23から射出された樹脂は温度を樹脂の溶融点に制御されたホ ットランナー用のマニホールド25内のランナーを通り、二手に別れてゲート4 0,40を通りキャビティ14,15に充填される。Next, the operation will be described. FIG. 1 shows that molding is performed by closing the molding device and pressing the nozzle 23 of the heating device 22 against the sprue bush of the fixed mold 18 to inject the resin. The resin injected from the nozzle 23 passes through the runner in the hot runner manifold 25 whose temperature is controlled to the melting point of the resin, and is divided into two parts to fill the cavities 14 and 15 through the gates 40 and 40.

【0023】 図2では射出終了後冷却を終え成形装置を開いたところを示す。キャビティ1 4は可動型19の雄型部の抜き勾配を大きくして固定型に成形品が保持されるよ うに留意している。キャビティ15は可動型19側を逆テーパーのアンダカット にしておき、成形品が可動型側に保持されるように留意してある。FIG. 2 shows a state where the cooling is completed after the injection is completed and the molding apparatus is opened. It is taken into consideration that the cavity 14 has a large draft of the male part of the movable mold 19 so that the molded product is held in the fixed mold. The cavity 15 is undercut with a reverse taper on the side of the movable die 19 so that the molded product is held on the side of the movable die.

【0024】 図3はシリンダ10を短縮して熱板13をキャビティ14の位置まで移動させ た状態を示す。実際は前にも説明したようにシリンダ10はキャビティ14の上 部に設置してあり、上方から下降してくることになる。それ故図面上でバー27 の長さに違いが有るが実際上は矛盾はない。FIG. 3 shows a state in which the cylinder 10 is shortened and the heating plate 13 is moved to the position of the cavity 14. Actually, as described above, the cylinder 10 is installed in the upper part of the cavity 14 and descends from above. Therefore, there is a difference in the length of the bar 27 on the drawing, but there is practically no contradiction.

【0025】 図4は可動型19をゆっくり閉鎖してキャビティ15の成形品の接合部37を 熱板13に押しつける。バー27はピン構造のジョイントに保持されているため 熱板13は固定型18側に押され、キャビティ14の接合部36に接触する。即 ちキャビティ14,15の成形品の接合部36,37を熱板13に押しつけ、当 該部分を加熱溶融する。該接合部36,37はRを付した形状で、熱板13を押 し付けた際に潰れてもハミ出しの起きない様に配慮されている。In FIG. 4, the movable mold 19 is slowly closed and the joint portion 37 of the molded product of the cavity 15 is pressed against the hot plate 13. Since the bar 27 is held by a joint having a pin structure, the hot plate 13 is pushed toward the fixed mold 18 and comes into contact with the joint portion 36 of the cavity 14. Immediately, the joints 36 and 37 of the molded products of the cavities 14 and 15 are pressed against the hot plate 13 and the portions are heated and melted. The joints 36 and 37 have a shape with a radius R, and are designed so that the humming does not occur even if the hot plate 13 is crushed when pressed.

【0026】 図5では成形装置を開き、可動型19の成形品の接続部37を熱板13から引 き離す。熱板13は横方向の押しつけ力が取れて可動型18の成形品の接続部3 6から離れて中立の位置に戻り、次にシリンダ10を伸長して該熱板13を金型 から退避させる。In FIG. 5, the molding device is opened, and the connecting portion 37 of the molded product of the movable mold 19 is separated from the hot plate 13. The hot plate 13 receives a lateral pressing force and returns to the neutral position away from the connection part 36 of the molded product of the movable mold 18, and then the cylinder 10 is extended to retract the hot plate 13 from the mold. .

【0027】 図6は可動型19を再度閉鎖して加熱溶融した成形品の接続部同士を押し付け た状態を示す。接合部36,37は加熱溶融しており。押し付けられて溶融部が 接着し、中空品38となる。この方法では接合部を均一に溶融しており接着ムラ がおきて内容物が漏洩する心配はない。FIG. 6 shows a state in which the movable mold 19 is closed again and the connecting portions of the heat-melted molded products are pressed against each other. The joint portions 36 and 37 are heated and melted. When pressed, the melted portion is bonded to form a hollow product 38. With this method, the joints are melted uniformly and there is no risk of leakage of the contents due to uneven adhesion.

【0028】 図7は接続部が冷却固化するのを待って可動型19を開く。中空品38は可動 型19側キャビティの逆テーパによるアンダーカットの結合が固定型18のキャ ビティの結合より強くしてあり、可動型19に保持され抜けてくる。In FIG. 7, the movable mold 19 is opened after waiting for the connection portion to cool and solidify. In the hollow product 38, the undercut coupling due to the reverse taper of the cavity on the movable die 19 side is stronger than the cavity coupling of the fixed die 18, and the hollow article 38 is retained by the movable die 19 and comes out.

【0029】 図8では、可動型19を開き可動盤21の開き限度まで開くと、成形機側に内 蔵のエジェクタ装置機構のエジェクタピン39にてエジェクタピン用孔12から エジェクタプレート35を押すことにより、中空品38は成形装置より外れ、下 に落下する。In FIG. 8, when the movable die 19 is opened and the movable platen 21 is opened to the open limit, the ejector plate 35 is pushed from the ejector pin hole 12 by the ejector pin 39 of the ejector device mechanism housed on the molding machine side. As a result, the hollow product 38 comes off the molding device and falls downward.

【0030】 以上で成形のサイクルが一周することになるが、この成形装置内に複数組の中 空品を作る機構を組込んで、同時に複数個の中空品を作ることは可能である。ま たホットランナをやめてストリッパープレートとリンク,チェーンによる通常の コールドランナ法式の採用も可能である。Although the molding cycle goes around once as described above, it is possible to simultaneously manufacture a plurality of hollow products by incorporating a mechanism for manufacturing a plurality of hollow products in this molding device. It is also possible to discontinue the hot runner and adopt the normal cold runner method using stripper plates, links, and chains.

【考案の効果】[Effect of device]

中空品のパーツ部品(成形品)に熱板を押しつけて接合端を加熱溶融し、溶融 した部分を互いに押し付けて中空状に直接容着するので所謂ポケットは発生しな い。また容着部の所要体積は最小済む。その上デザイン上の自由度が増す。 Since a hot plate is pressed against a hollow part (molded product) to heat and melt the joint ends, and the melted parts are pressed against each other and directly adhered in a hollow shape, so-called pockets do not occur. Moreover, the required volume of the attachment portion is minimized. Moreover, the degree of freedom in design increases.
