Abstract

PROBLEM TO BE SOLVED: To prevent the damage or wrinkling of a skin or to prevent the release with a base material resin by pressing the skin over the total length of the edge part thereof by a press ring and spreading a molten resin over the surface of the skin and also ejecting the molten resin even to the outside and subsequently allowing the press ring to retreat. SOLUTION: A skin 14 is set to the cavity surface of a moving mold 10 at a predetermined position. The moving mold 10 is allowed to advance to a predetermined position and the skin 14 is pressed over the total length thereof by the press ring 18 of a cylinder 19. At this time, a space part 20 of about 30mm is formed. A dumpling shaped molten resin is injected into the space part 20 and the moving mold 10 is allowed to advance until a compression flange becomes about 3-4mm to spread the molten resin on the surface of the skin 14 to be closely bonded thereto. Next, the molten resin is also injected into the outside of the space part 20 and the moving mold 10 is allowed to advance to compress the compression flange and the press ring 18 is allowed to retreat while the bonding of the molten resin in the space part 20 and the outside molten resin is achieved.

【0001】 [0001]

【産業上の利用分野】本発明は表皮を型内に配置して一体成形をし、成形体表面の一部に表皮を有す成形体の製造方法に関んする。 BACKGROUND OF THE INVENTION This invention is an integrally molded by placing in a mold the epidermis, to N relating to the process for producing a molded article which have a skin on the part of the surface of the molded product.

【0002】 [0002]

【従来技術】近年、自動車の内装部品には樹脂基材を塩ビレザー等の表皮で表面を被覆したものが使用されていが、この様な内装部品の製造は価格的および見栄え上から表皮を型内に配置して一体成形をすること行われている。 BACKGROUND ART In recent years, the interior parts of automobiles have been used those obtained by coating the surface of the resin substrate with the skin, such as salts Bireza but mold skin from such interior parts manufacturing cost and appearance on It has been made to the integral molding and arranged within.

【0003】その方法を図8ないし図10により説明すると、雌型1内の凹部2に表皮3をセットし、雄型4との間に圧縮代δを残して型閉じを行い、射出ゲート5から金型キャビテイ6内に基材樹脂7となる溶融樹脂を射出し、図10のように圧縮代δを圧縮する方法であった。 [0003] With reference to FIG 8 to FIG 10 the process sets the skin 3 in the recess 2 of the female mold 1 performs mold closing, leaving a compression allowance δ between the male mold 4, injection gate 5 injecting a molten resin as a base material resin 7 in the mold cavity 6 from was a method for compressing the compression allowance δ as shown in Figure 10.

【0004】 [0004]

【発明が解決しょうとする課題】従って前述のような表皮と基材樹脂を一体成形する場合、射出された樹脂の圧力が高すぎて表皮が破損したり、皺ができたり或いは表皮が所定位置からズレたりする等の欠点があった。 OBJECTS OF THE INVENTION It'll solve] Therefore, when integrally molding the skin and base resin as described above may damage the epidermis pressure injected resin is too high, you are wrinkled or or epidermis predetermined position there is a drawback of such or deviated from. また両型を小間隙の型開き状態で溶融樹脂を射出し、圧縮していたので、溶融樹脂がキャビティ末端まで届きにくく、末端に該当する表皮と基材樹脂との接着不良が起きやすく、表皮と基材樹脂の剥離が起きた。 Also the dies by injecting a molten resin in a mold open state of the small gap, so was compressed, impair access to a molten resin cavity end, the epidermis and the base resin adhesion failure is liable to occur between the corresponding to the terminal, the epidermis peeling of the base resin and has occurred.

【0005】本発明の目的は前述のような表皮が破損や皺ができたりする欠点、或いは表皮と基材樹脂の剥離となるような欠点を取除いた表皮を表面の一部に有する樹脂成形体の製造方法を提供することにある。 [0005] Resin molded object having disadvantages skin such as described above or can damage or wrinkles, or the disadvantage preparative except epidermis such that peeling of the skin and the substrate resin portion of the surface of the present invention and to provide a manufacturing method of the body.

【0006】 [0006]

【課題を解決するための手段】前述の目的を達成するため本発明は型開状態の両金型のいずれか一側に表皮をセットした後、他側金型側に設けた押さえリングにより前記表皮を縁部全長に亘って押さえるとともに、表皮面上に他側金型と協動して空間部を形成し、第1の射出装置により同空間部に溶融樹脂を団子状に注入し、次いで前記空間部の溶融樹脂を圧縮し、所定の圧縮代を残して同樹脂を表皮面上に押拡げた後、第2の射出装置により押さえリングが囲った空間部の外側の金型キャビテイに溶融樹脂を射出し、更に前記圧縮代を圧縮することにより金型キャビテイを圧縮するとともに、前記押さえリングを表皮面上から後退させるようにした表皮を表面の一部に有する樹脂成形体の製造方法とした。 Means for Solving the Problems The present invention for achieving the foregoing object after setting the epidermis in any one side of the molds in the mold open state, the by pressing ring provided on the other side mold side with pressed over the skin at the edge entire length, in cooperation with the other side die on the skin surface to form a space portion, a molten resin is injected bunching in the space portion by the first injection unit, then compressing the molten resin in the space portion, after 押拡 clogs the same resin while leaving a predetermined compression margin on the skin surface, the melt outside the mold cavity of the space surrounded the pressing ring by the second injection unit the resin is injected, and further while compressing the mold cavity by compressing the compression allowance, method for producing a resin molded article having a skin which is adapted to retract the pressing ring from the skin surface part of the surface did.

【0007】また第2の射出装置による溶融樹脂の射出後の金型キャビテイの圧縮は第2の射出装置のバルブゲートを開いた状態で行うことを特徴とする前記表皮を表面の一部に有する樹脂成形体の製造方法とした。 Further compression of the mold cavity after the injection of the molten resin due to the second injection device having a skin which is characterized in that in a state of opening the valve gate of the second injection unit on a part of the surface and as the manufacturing method of the resin molded body.
