Description

本発明は、成形体の金型装置および成形体の製造方法に関する。   The present invention relates to a mold apparatus for a molded body and a method for manufacturing the molded body.

従来、真空成形法を用いて成形体を製造する各種の技術が知られている(例えば、特許文献1参照。)。   Conventionally, various techniques for producing a molded body using a vacuum forming method are known (for example, see Patent Document 1).

図8〜図10は、真空成形法を用いた従来の技術を説明する図である。
図8(a)および(b)に示すように、金型装置100は、芯材101および表皮材102からなる車両用内装材103が複数連なる成形体105を成形するものであり、下型106のみで構成される。下型106には、複数の凸部107を有する成形面108と、真空吸引機構111とが設けられる。この金型装置100を用いた成形体105の製造では、複数の凸部107のそれぞれに芯材101をセットした後、真空吸引機構111により複数の凸部107に沿って表皮材102を真空成形する。そして、成形体した成形体105をいわゆるピアス工程などの切断工程に送り、一点鎖線で示される切断位置で表皮材102を切断し、所定形状の複数の車両用内装材103を得る。
8-10 is a figure explaining the prior art using the vacuum forming method.
As shown in FIGS. 8A and 8B, the mold apparatus 100 forms a molded body 105 in which a plurality of vehicle interior materials 103 including a core material 101 and a skin material 102 are continuous, and a lower mold 106. Consists of only. The lower mold 106 is provided with a molding surface 108 having a plurality of convex portions 107 and a vacuum suction mechanism 111. In the manufacture of the molded body 105 using the mold apparatus 100, the core material 101 is set on each of the plurality of convex portions 107, and then the skin material 102 is vacuum formed along the plurality of convex portions 107 by the vacuum suction mechanism 111. To do. Then, the formed body 105 is sent to a cutting process such as a so-called piercing process, and the skin material 102 is cut at a cutting position indicated by a one-dot chain line to obtain a plurality of vehicle interior materials 103 having a predetermined shape.

しかしながら、このような成形体105の製造においては、上記のように切断工程が必要であるため、ピアス型やプレス機などが別途必要であり、製造コストが高くなるという問題がある。この問題を解消するには、図9に示すように、切断部112を備える上型113を追加し、この上型113を成形体105の成形後に下降して、切断部112で表皮材102を切断することが有効である。この場合、ピアス型などが不要であるため、製造コストを低く抑えることができる。   However, in the production of such a molded body 105, since a cutting process is necessary as described above, a piercing die, a press machine, and the like are separately required, and there is a problem that the manufacturing cost increases. In order to solve this problem, as shown in FIG. 9, an upper mold 113 having a cutting part 112 is added, and the upper mold 113 is lowered after forming the molded body 105, and the skin material 102 is moved by the cutting part 112. It is effective to cut. In this case, since a piercing type or the like is unnecessary, the manufacturing cost can be kept low.

また、図8(a)に示される金型装置100においては、真空吸引のみによって成形体105を成形するため、凸部107に沿って表皮材102が十分に伸ばされず、成形品質が低下するおそれがある。このような場合、図10に示すように、圧空機構115を備える上型113を追加することが好適である。すなわち、環状の圧受け部116を上型113に設け、圧受け部116の下端116aと下型106の合わせ面117をシールする。そして、真空吸引機構111により表皮材102を真空成形しつつ、圧受け部116で囲われる密閉空間118に圧空機構115によって加圧空気を供給し、表皮材102を圧空成形する。これにより、表皮材102を良好に伸ばすことができ、成形品質を高めることができる。   Further, in the mold apparatus 100 shown in FIG. 8A, since the molded body 105 is molded only by vacuum suction, the skin material 102 is not sufficiently stretched along the convex portion 107, and the molding quality may be deteriorated. There is. In such a case, as shown in FIG. 10, it is preferable to add an upper mold 113 including a compressed air mechanism 115. That is, the annular pressure receiving portion 116 is provided on the upper mold 113, and the lower end 116 a of the pressure receiving portion 116 and the mating surface 117 of the lower mold 106 are sealed. Then, while the skin material 102 is vacuum-formed by the vacuum suction mechanism 111, pressurized air is supplied to the sealed space 118 surrounded by the pressure receiving portion 116 by the pressure air mechanism 115, and the skin material 102 is pressure-air molded. Thereby, the skin material 102 can be extended favorably and molding quality can be improved.

ところで、品質が高く、しかも安価な成形体が求められる中、真空成形法を用いる成形体の製造には、圧空成形と成形体の切断を両立させる技術が求められている。   By the way, while a high-quality and inexpensive molded body is required, a technique for achieving both compression molding and cutting of the molded body is required for manufacturing a molded body using a vacuum forming method.

特開2004−351937号公報JP 2004-351937 A

そこで、図10に示される金型装置100に切断部を追加する場合について考える。表皮材102を切断部で切断するには、圧受け部116よりも下方に切断部を突出させる必要がある。また、圧空機構115によって、表皮材102を圧空成形するには、圧受け部116の下端116aと下型106の合わせ面117をシールして、密閉空間118を形成する必要がある。   Therefore, consider a case where a cutting part is added to the mold apparatus 100 shown in FIG. In order to cut the skin material 102 at the cutting portion, the cutting portion needs to protrude below the pressure receiving portion 116. Further, in order to perform the air pressure molding of the skin material 102 by the pressure air mechanism 115, it is necessary to seal the lower end 116 a of the pressure receiving portion 116 and the mating surface 117 of the lower mold 106 to form a sealed space 118.

したがって、圧空機構115と切断部を上型106に単に組み合わせて設けた場合、圧受け部116の下端116aよりも下方に切断部が突出することから、圧受け部116の下端116aと合わせ面117がシールされる前(圧空成形する前)に、切断部が表皮材102に接触してしまい、表皮材102が十分に伸ばされる前に切断されることになる。その結果、表皮材102が短く形成されるため、高い成形品質が得られない。このため、圧空成形と成形体の切断を両立できる新たな技術開発が望まれる。   Accordingly, when the compressed air mechanism 115 and the cutting portion are simply combined with the upper mold 106, the cutting portion protrudes below the lower end 116a of the pressure receiving portion 116, so that the lower end 116a of the pressure receiving portion 116 and the mating surface 117 are provided. Before the seal is sealed (before pressure forming), the cut portion comes into contact with the skin material 102 and is cut before the skin material 102 is sufficiently stretched. As a result, since the skin material 102 is formed short, high molding quality cannot be obtained. For this reason, new technical development that can achieve both compression molding and cutting of the molded body is desired.

本発明は、このような事情に鑑みてなされたものであり、真空成形法を用いる成形体の製造において、圧空成形と成形体の切断を両立させ、製造コストの低減および成形品質の向上が実現できる成形体の金型装置および成形体の製造方法を提供することにある。   The present invention has been made in view of such circumstances. In the production of a molded body using a vacuum forming method, both compression molding and cutting of the molded body are achieved, and the manufacturing cost is reduced and the molding quality is improved. An object of the present invention is to provide a mold apparatus for a molded body and a method for producing the molded body.

(Configuration of upper mold 23)
On the other hand, the upper die 23 includes an upper base 41, a pressure receiving portion 42 provided on the lower side of the upper base 41, and a lower end 42a of the pressure receiving portion 42 facing the lower die 22 (referred to as “pressure receiving portion” in the present invention). And a driving means 50 for moving the movable body 43. Further, the upper mold 23 is provided with a pneumatic mechanism 45 and a plurality of cutting portions 46.

圧受け部42は、上部基盤41の下面に設けられると共に上部基盤41の外周に沿って環状に設けられる。この例では、上部基盤41の下方空間を4方向から囲うようにして、合計の4個の板状の圧受け部42(図では、対向する2個の圧受け部42を示す)を設ける。すなわち、4個の圧受け部42によって、4つの側面からなる上型23の外周壁が形成される。   The pressure receiving portion 42 is provided on the lower surface of the upper base 41 and is provided annularly along the outer periphery of the upper base 41. In this example, a total of four plate-like pressure receiving portions 42 (in the figure, two opposing pressure receiving portions 42 are shown) are provided so as to surround the lower space of the upper base 41 from four directions. That is, the four pressure receiving portions 42 form an outer peripheral wall of the upper mold 23 having four side surfaces.

図4に示すように、可動体43は、圧受け部42と同程度の厚みで形成される板状の部材であり、4個の圧受け部42のそれぞれの下端42aに設けられる。4個の可動体43のそれぞれは、駆動手段50により、圧受け部42の下端42aから上型23の外方に向けて(矢印(A)で示す向きに)移動可能である。   As shown in FIG. 4, the movable body 43 is a plate-like member formed with the same thickness as the pressure receiving portion 42, and is provided at the lower end 42 a of each of the four pressure receiving portions 42. Each of the four movable bodies 43 can be moved by the driving means 50 from the lower end 42a of the pressure receiving portion 42 toward the outside of the upper mold 23 (in the direction indicated by the arrow (A)).

駆動手段50は、圧受け部42に固定されるガイド軸51と、このガイド軸51にすべり軸受け52を介して設けられガイド軸51の軸方向に沿って移動可能な支持プレート53と、この支持プレート53の外面に固定されるシリンダユニット55とによって構成される。可動体43は、支持プレート53の内面の下部に固定される。   The driving means 50 includes a guide shaft 51 fixed to the pressure receiving portion 42, a support plate 53 provided on the guide shaft 51 via a slide bearing 52 and movable along the axial direction of the guide shaft 51, and the support The cylinder unit 55 is fixed to the outer surface of the plate 53. The movable body 43 is fixed to the lower part of the inner surface of the support plate 53.

シリンダユニット55は、空圧または油圧で作動するものであり、支持プレート53の外面に固定されるシリンダ56と、このシリンダ56から支持プレート53を貫通して圧受け部42の外面に固定されるロッド57とで構成される。   The cylinder unit 55 is operated by pneumatic pressure or hydraulic pressure, and is fixed to the outer surface of the pressure receiving portion 42 through the cylinder 56 that is fixed to the outer surface of the support plate 53 and the support plate 53 from the cylinder 56. And a rod 57.

なお、圧受け部42とガイド軸51を固定する手段や、可動体43と支持プレート53を固定する手段、支持プレート53とシリンダ56を固定する手段、圧受け部42とロッド57を固定する手段は、ねじ部材による締結を含む各種の固定手段から選択可能である。   A means for fixing the pressure receiving portion 42 and the guide shaft 51, a means for fixing the movable body 43 and the support plate 53, a means for fixing the support plate 53 and the cylinder 56, and a means for fixing the pressure receiving portion 42 and the rod 57. Can be selected from various fixing means including fastening by screw members.

図4では、シリンダ56内にロッド57が没入した状態のシリンダユニット55を示しており、この状態では、支持プレート53が圧受け部42の外面に接近し、可動体43が圧受け部42の下端42aに(圧受け部42の直下に)位置している。   FIG. 4 shows the cylinder unit 55 in a state in which the rod 57 is immersed in the cylinder 56. In this state, the support plate 53 approaches the outer surface of the pressure receiving portion 42, and the movable body 43 moves to the pressure receiving portion 42. It is located at the lower end 42a (directly below the pressure receiving portion 42).

このように可動体43が圧受け部42の下端42aに位置した状態から、シリンダユニット55が作動すると、ロッド57が伸びてシリンダ56が圧受け部42から離れる方向(矢印(A)で示す向き)に移動する。これにより、支持プレート53がガイド軸51に案内されながら、圧受け部42の外面から離れる方向に移動するため、可動体43も支持プレート53と共に矢印(A)で示す向きに移動し、圧受け部42の下端42aから外れる。   When the cylinder unit 55 is operated from the state in which the movable body 43 is positioned at the lower end 42a of the pressure receiving portion 42 as described above, the rod 57 extends and the cylinder 56 moves away from the pressure receiving portion 42 (the direction indicated by the arrow (A)). ) As a result, the support plate 53 moves in a direction away from the outer surface of the pressure receiving portion 42 while being guided by the guide shaft 51, so that the movable body 43 also moves in the direction indicated by the arrow (A) together with the support plate 53. The part 42 is disengaged from the lower end 42a.

圧受け部42の下端42aから可動体43が外れた状態において、ロッド57がシリンダ56に没入すると、シリンダ56が圧受け部42に接近する方向(矢印(B)で示す向き)に移動する。これにより、支持プレート53がガイド軸51に案内されながら、圧受け部42に接近する方向に移動するため、可動体43も矢印(B)で示す向きに移動して支持プレート53の下端42aに戻る。   In a state where the movable body 43 is detached from the lower end 42a of the pressure receiving portion 42, when the rod 57 is immersed in the cylinder 56, the cylinder 56 moves in a direction approaching the pressure receiving portion 42 (direction indicated by an arrow (B)). As a result, the support plate 53 moves in the direction approaching the pressure receiving portion 42 while being guided by the guide shaft 51, so the movable body 43 also moves in the direction indicated by the arrow (B) and moves to the lower end 42 a of the support plate 53. Return.

なお、駆動手段50の構成は、格別に限定されるものではないが、上記のように支持プレート53の動作をガイド軸51で案内する構成を採用することで、可動体43を高い位置精度で円滑に動作させることができる。   The configuration of the driving unit 50 is not particularly limited, but by adopting the configuration in which the operation of the support plate 53 is guided by the guide shaft 51 as described above, the movable body 43 can be positioned with high positional accuracy. It can be operated smoothly.

以上のように、圧受け部42に対して可動体43を移動させることにより、金型装置20では、可動体43を嵩上げ部品として機能させ、成形金型21のダイハイト(型締め状態における上部基盤41から下部基盤27までの距離)を調整する。すなわち、可動体43が圧受け部42の下端42aに位置した状態で成形金型21が閉じると、下型22の合わせ面33に可動体43の下端43a(本発明にいう「可動体の先端」に相当)が当接し、上型23と下型22の間に可動体43が挟まれるため、ダイハイトは、可動体43の高さ方向の寸法h(例えば、20mm程度)を含む大きさになる。一方、圧受け部42の下端42aから可動体43が移動して抜かれた状態で成形金型21が閉じると、下型22の合わせ面33に圧受け部42の下端42aが当接するため、上型23と下型22の間に可動体43が挟まれたときよりも、可動体43の寸法hだけダイハイトが小さくなる。   As described above, by moving the movable body 43 with respect to the pressure receiving portion 42, the mold device 20 causes the movable body 43 to function as a raised part, and the die height of the molding die 21 (upper base in the mold-clamped state). 41 to the lower base 27). That is, when the molding die 21 is closed with the movable body 43 positioned at the lower end 42 a of the pressure receiving portion 42, the lower end 43 a of the movable body 43 (referred to as “the tip of the movable body” in the present invention) is placed on the mating surface 33 of the lower mold 22. ”) And the movable body 43 is sandwiched between the upper mold 23 and the lower mold 22, so that the die height includes a dimension h (for example, about 20 mm) in the height direction of the movable body 43. Become. On the other hand, when the molding die 21 is closed with the movable body 43 moved and removed from the lower end 42 a of the pressure receiving portion 42, the lower end 42 a of the pressure receiving portion 42 contacts the mating surface 33 of the lower die 22. The die height is smaller by the dimension h of the movable body 43 than when the movable body 43 is sandwiched between the mold 23 and the lower mold 22.

図3に戻る。図3に示すように、圧空機構45は、可動体43が圧受け部42の下端42aに位置した状態において成形金型21が閉じたとき、圧受け部42、可動体43、上部基盤41および表皮材シート15で囲われる密閉空間62(図5(b)参照)に、空圧源61から弁63を介して加圧空気を供給し、表皮材シート15を圧空成形する。   Returning to FIG. As shown in FIG. 3, when the molding die 21 is closed in a state where the movable body 43 is positioned at the lower end 42a of the pressure receiving portion 42, the pressure receiving mechanism 42, the movable body 43, the upper base 41, and Pressurized air is supplied from the air pressure source 61 to the sealed space 62 (see FIG. 5B) surrounded by the skin material sheet 15 via the valve 63, and the skin material sheet 15 is compressed and formed.

図4に示すように、切断部46は、複数の凸部31のそれぞれに対応して配置される環状の切断刃である。各切断部46の下端46aは、圧受け部42の下端42aよりも下方(下型22側)に突出し、且つ、高さ方向において可動体43の寸法hの範囲内に位置する。また、凸部31の周縁近傍には、切断部46の下端46aを受ける環状の嵌合溝65が設けられており、各切断部46は、後述する切断工程において成形金型21が閉じたとき、環状の嵌合溝65に嵌合する。   As shown in FIG. 4, the cutting portion 46 is an annular cutting blade that is arranged corresponding to each of the plurality of convex portions 31. The lower end 46a of each cutting part 46 protrudes downward (lower mold 22 side) from the lower end 42a of the pressure receiving part 42, and is located within the range of the dimension h of the movable body 43 in the height direction. Further, an annular fitting groove 65 that receives the lower end 46a of the cutting portion 46 is provided in the vicinity of the periphery of the convex portion 31, and each cutting portion 46 is formed when the molding die 21 is closed in a cutting step that will be described later. It fits in the annular fitting groove 65.

(成形体10の製造方法)
続いて、成形体10の製造方法を図5〜図7に基づいて説明する。
この製造方法は、成形工程および切断工程を含む。
(Manufacturing method of the molded object 10)
Then, the manufacturing method of the molded object 10 is demonstrated based on FIGS.
This manufacturing method includes a forming step and a cutting step.

(成形工程)
図5(a)に示すように、成形工程の第1段階では、芯材12を凸部31にセットした後、クランプ25で保持された表皮材シート15を、真空吸引機構26(図3参照)により成形面32に沿って真空成形する(矢印(1))。すなわち、表皮材シート15を芯材12に圧着させながら、凸部31に沿って伸ばす。
(Molding process)
As shown in FIG. 5A, in the first stage of the molding process, after the core material 12 is set on the convex portion 31, the skin material sheet 15 held by the clamp 25 is removed from the vacuum suction mechanism 26 (see FIG. 3). ) To form a vacuum along the forming surface 32 (arrow (1)). That is, the skin material sheet 15 is stretched along the convex portion 31 while being crimped to the core material 12.

図5(b)に示すように、成形工程の第2段階では、圧受け部42の下端42a(図4参照)に可動体43を位置させた状態で、上型23を下降し(矢印(2))、成形金型21を閉じる。これにより、可動体43の下端43a(図4参照)が下型22の合わせ面33(図4参照)に当接するため、可動体43と合わせ面33(図4参照)とがシールされ、圧受け部42、可動体43、上部基盤41および表皮材シート15で囲われる密閉空間62が形成される。次に、下型22において真空成形を行いつつ(矢印(1))、圧空機構45(図3参照)により、密閉空間62に加圧空気を供給して表皮材シート15を圧空成形する(矢印(3))。この圧空成形により、表皮材シート15が凸部31に沿ってさらに伸びるため、成形面32の形状通りに成形された成形体10が得られる。   As shown in FIG. 5 (b), in the second stage of the molding process, the upper mold 23 is lowered (arrow (2)) with the movable body 43 positioned at the lower end 42a of the pressure receiving portion 42 (see FIG. 4). 2)), the molding die 21 is closed. Thereby, since the lower end 43a (refer FIG. 4) of the movable body 43 contact | abuts to the mating surface 33 (refer FIG. 4) of the lower mold | type 22, the movable body 43 and the mating surface 33 (refer FIG. 4) are sealed, and pressure A sealed space 62 surrounded by the receiving portion 42, the movable body 43, the upper base 41 and the skin sheet 15 is formed. Next, while vacuum forming is performed in the lower mold 22 (arrow (1)), the compressed air mechanism 45 (see FIG. 3) is used to supply pressurized air to the sealed space 62 to pressure-mold the skin sheet 15 (arrow). (3)). By this pressure forming, the skin material sheet 15 further extends along the convex portion 31, so that the molded body 10 molded according to the shape of the molding surface 32 is obtained.

図7(a)に示すように、この成形工程の第2段階では、切断部46が下型22に対して離間した状態で成形金型21が閉じており、切断部46は、表皮材シート15に接触していない。   As shown in FIG. 7 (a), in the second stage of the molding process, the molding die 21 is closed with the cutting portion 46 being separated from the lower mold 22, and the cutting portion 46 is a skin material sheet. 15 is not touching.

(切断工程)
図6(a)に示すように、切断工程の第1段階では、成形体10が成形された後、上型23を上昇させ(矢印(4))、成形金型21を開く。そして、駆動手段50により、圧受け部42の下端42aから可動体43を上型23の外方に移動し(矢印(5))、クランプ25を外して成形体10の両端を解放する。
(Cutting process)
As shown in FIG. 6A, in the first stage of the cutting process, after the molded body 10 is molded, the upper mold 23 is raised (arrow (4)), and the molding die 21 is opened. Then, the driving means 50 moves the movable body 43 from the lower end 42a of the pressure receiving portion 42 to the outside of the upper mold 23 (arrow (5)), removes the clamp 25, and releases both ends of the molded body 10.

図6(b)に示すように、切断工程の第2段階では、上型23を再度下降し(矢印(6))、成形金型21を閉じる。この型閉めでは、図7(b)に示すように、圧受け部42の下端42aが下型22の合わせ面33に当接するため、成形時の型閉め(図7(a)参照)よりも下型22および上型23が接近する。すなわち、切断工程におけるダイハイトH1は、成形工程におけるダイハイトH2(図7(a)参照)よりも可動体43の寸法h(図4参照)だけ小さくなる。これにより、切断部46が表皮材13に接触可能な状態で成形金型21が閉じるため、切断部46の下端46aを嵌合溝65に嵌合させながら表皮材13に食い込ませ(矢印(7))、芯材12の周縁に沿って、表皮材13を所定の外形形状に切断(トリミング)することができる。   As shown in FIG. 6B, in the second stage of the cutting process, the upper mold 23 is lowered again (arrow (6)), and the molding die 21 is closed. In this mold closing, as shown in FIG. 7B, the lower end 42a of the pressure receiving portion 42 abuts against the mating surface 33 of the lower mold 22, so that the mold closing at the time of molding (see FIG. 7A). The lower mold 22 and the upper mold 23 approach each other. That is, the die height H1 in the cutting process is smaller by the dimension h (see FIG. 4) of the movable body 43 than the die height H2 (see FIG. 7A) in the molding process. As a result, the molding die 21 is closed in a state where the cutting portion 46 can contact the skin material 13, so that the lower surface 46 a of the cutting portion 46 is fitted into the fitting groove 65 and bites into the skin material 13 (arrow (7 )), The skin material 13 can be cut (trimmed) into a predetermined outer shape along the periphery of the core material 12.

以上、説明した実施形態の効果について述べる。
本実施形態によれば、表皮材シート15を圧空成形する際は、切断部46を表皮材シート15に接触させず、成形体10を切断する際は、下型22および上型23をより接近させて成形体10に切断部46を接触させることができる。これにより、複数の車両用内装材11を同時に製造する複数個取りの成形体10の製造において、圧空成形と成形体10の切断を両立させ、型費、設備費、製造工数を抑えて製造コストを低減することができる。また、成形面32において大きく伸ばされる高展開部を有する成形体10の製造においても、圧空成形を行うことができるため、高い成形品質を得ることができる。
The effects of the embodiment described above will be described.
According to this embodiment, when the skin material sheet 15 is subjected to pressure forming, the cutting portion 46 is not brought into contact with the skin material sheet 15, and when the molded body 10 is cut, the lower die 22 and the upper die 23 are brought closer to each other. Thus, the cutting portion 46 can be brought into contact with the molded body 10. As a result, in the production of a plurality of molded bodies 10 for simultaneously producing a plurality of vehicle interior materials 11, both compression molding and cutting of the molded body 10 can be performed at the same time, and the manufacturing cost can be reduced while reducing mold costs, equipment costs, and manufacturing man-hours. Can be reduced. Further, in the production of the molded body 10 having a highly developed portion that is greatly stretched on the molding surface 32, since the compressed air molding can be performed, high molding quality can be obtained.

以上、実施形態を用いて本発明を説明したが、本発明の技術的範囲は上記実施形態に記載の範囲には限定されないことは言うまでもない。上記実施形態に、多様な変更または改良を加えることが可能であることが当業者に明らかである。またその様な変更または改良を加えた形態も本発明の技術的範囲に含まれ得ることが、特許請求の範囲の記載から明らかである。   As mentioned above, although this invention was demonstrated using embodiment, it cannot be overemphasized that the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiments.
