Abstract

<P>PROBLEM TO BE SOLVED: To provide a method and a device for observing the inside of the mold which enable the clear observation of the foaming behavior of amorphous resins having high transparency and even the foaming behavior of those having low transparency. <P>SOLUTION: A pair of transparent bodies 11 and 12 are incorporated in a mold 1 for injection foaming molding so as to face each other with a cavity 4 between them. Illuminating light emitted from a light source 13 is allowed to enter the cavity 4 from the transparent body 11 through a red transparent plate 17, and the transmitted light is received by a high-speed camera 16 through the transparent body 12. Short-wavelength components in the illuminating light which tend to be scattered easily are removed by the red transparent plate 17, and most of scattered light scattered by spherulites and bubbles generated in foaming are removed by a polarizing plate, resulting in clear images of high-speed camera 16. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明は、射出発泡成形用金型内における樹脂材料の発泡挙動を観察するための型内観察方法および型内観察装置に関する。   The present invention relates to an in-mold observation method and an in-mold observation apparatus for observing the foaming behavior of a resin material in an injection foam molding mold.

射出発泡成形において、金型内における樹脂材料の発泡挙動を知ることは、高品質の発泡成形体を得る上で重要である。そして従来、射出発泡成形用金型内にキャビティに臨んでガラス体を組込み、該ガラス体を通して照明光をキャビティ内に入射し、その反射光を撮像手段(高速度カメラ)で受光して樹脂材料の発泡挙動を観察することが、既に行われている(たとえば、非特許文献1参照)。   In the injection foam molding, knowing the foaming behavior of the resin material in the mold is important for obtaining a high-quality foam molded article. Conventionally, a glass body is assembled into an injection foam molding die facing the cavity, illumination light is incident on the cavity through the glass body, and the reflected light is received by an imaging means (high speed camera). Has already been observed (see, for example, Non-Patent Document 1).

しかしながら、従来、型内観察の対象となる樹脂材料は、ポリスチレン(PS)、アクリル系樹脂、ポリカーボネート(PC)などの透明度が高い非晶性の樹脂に限られていた。これは、反射方式を採用しているため、ポリプロピレン(PP)などの透明度が低い結晶性の樹脂では、照射光の大部分が表面で反射してしまい、内奥部の可視化が困難になることに加え、かりに、内奥部を可視化できても、球晶や気泡による光の散乱によって鮮明な映像(撮像)が得にくいことが原因している。また、前記のような透明度の高い樹脂を対象にした場合でも、板厚方向に多数重なり合って発生する気泡による光の散乱によって鮮明な撮像が得にくく、特に内奥部の観察が困難である、という問題があった。   However, conventionally, resin materials to be observed in the mold have been limited to amorphous resins having high transparency such as polystyrene (PS), acrylic resin, and polycarbonate (PC). Because this uses a reflection method, a crystalline resin with low transparency, such as polypropylene (PP), reflects most of the irradiation light on the surface, making it difficult to visualize the inner part. In addition, even if the inner inner part can be visualized, it is because it is difficult to obtain a clear image (imaging) due to light scattering by spherulites and bubbles. In addition, even when targeting a highly transparent resin as described above, it is difficult to obtain clear imaging due to light scattering due to bubbles generated by overlapping in the thickness direction, and it is particularly difficult to observe the inner part, There was a problem.

本発明は、上記した従来の技術的背景に鑑みてなされたもので、その課題とするところは、透明度が高い非晶性の樹脂はもちろん、透明度が低い結晶性の樹脂であっても明瞭に発泡挙動を観察できる型内観察方法および型内観察装置を提供することにある。   The present invention has been made in view of the above-described conventional technical background, and the subject is clearly an amorphous resin having a high transparency as well as a crystalline resin having a low transparency. An object of the present invention is to provide an in-mold observation method and an in-mold observation apparatus that can observe foaming behavior.

以下、本発明を実施するための最良の形態を添付図面に基づいて説明する。   The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

図1および2は、本発明に係る型内観察装置の一つの実施形態を示したものである。図1において、1は、固定型2と可動型3とからなる射出発泡成形用金型であり、固定型2に対して可動型3を型閉じすることで、両者の間には成形空間としてのキャビティ4が形成される。キャビティ4は、紙面に垂直方向へ広がりを有しており、キャビティ4内には、固定型2内に設けられた、図示を略すホットランナーおよびゲートを経て溶融樹脂(発泡樹脂材)Mが射出(加圧注入)されるようになっている。   1 and 2 show an embodiment of an in-mold observation apparatus according to the present invention. In FIG. 1, reference numeral 1 denotes an injection foam molding die composed of a fixed mold 2 and a movable mold 3. By closing the movable mold 3 with respect to the fixed mold 2, a molding space is formed between the two. The cavity 4 is formed. The cavity 4 extends in a direction perpendicular to the paper surface, and molten resin (foamed resin material) M is injected into the cavity 4 via a hot runner and a gate (not shown) provided in the fixed mold 2. (Pressurized injection).

本型内観察装置10は、可動型3および固定型2のそれぞれにキャビティ4を挟んで対向して組込まれた一対の透明体11、12と、照明光を放出する光源13と、該光源13からの照明光を可動型3に形成した貫通孔3aを経て一方の透明体11に導光する光ファイバーケーブル14と、他方の透明体12から出射された照明光の透過光を、固定型2に形成した貫通孔2aおよび固定型2に付設したミラー15を介して受光する高速度カメラ(撮像手段)16と、一方の透明体11の前面に配置された赤色系の透明板17と、撮像手段16の前面に回転可能に配置された偏光板18とを備えている。なお、各透明体11、12は、ここでは可動型3および固定型2にボルト止めした押え板19によって、対応する型に緩衝体20を介して固定されている。   The in-mold observation apparatus 10 includes a pair of transparent bodies 11 and 12 that are assembled to face each of the movable mold 3 and the fixed mold 2 with the cavity 4 interposed therebetween, a light source 13 that emits illumination light, and the light source 13. The optical fiber cable 14 that guides the illumination light from the other transparent body 11 through the through hole 3 a formed in the movable mold 3 and the transmitted light of the illumination light emitted from the other transparent body 12 to the fixed mold 2. A high-speed camera (imaging means) 16 that receives light through the formed through-hole 2a and a mirror 15 attached to the fixed mold 2, a red transparent plate 17 disposed on the front surface of one transparent body 11, and an imaging means 16 is provided with a polarizing plate 18 rotatably disposed on the front surface. Each transparent body 11, 12 is fixed to the corresponding mold via a buffer body 20 by a press plate 19 bolted to the movable mold 3 and the fixed mold 2 here.

ここで、上記透明体11、12としては、高強度でかつ高耐熱性を有するガラス、たとえば石英ガラスが用いられる。また、光源13の種類は任意であるが、大きな光量が簡単に得られ、しかもキャビティ4内の溶融樹脂Mに対する発熱影響の少ないものを選択するのが望ましい。このような光源としては、たとえば水銀灯がある。また、高速度カメラ16の種類も任意であるが、別途画像解析等を行いたい場合は、高速度デジタルカメラを用いるのが望ましい。   Here, as the transparent bodies 11 and 12, glass having high strength and high heat resistance, for example, quartz glass is used. The type of the light source 13 is arbitrary, but it is desirable to select a light source that can easily obtain a large amount of light and that has little influence on the molten resin M in the cavity 4. An example of such a light source is a mercury lamp. The type of the high-speed camera 16 is arbitrary, but it is desirable to use a high-speed digital camera when it is desired to perform image analysis separately.

以下、上記のように構成した型内観察装置10による型内観察方法を説明する。   Hereinafter, an in-mold observation method using the in-mold observation apparatus 10 configured as described above will be described.

溶融樹脂Mは、前記したようにホットランナーからゲートを経てキャビティ4内に射出され、先端部で発泡を起こしながらキャビティ4内の周辺へ流動する。本型内観察装置10を構成する光源13および高速度カメラ16は、前記したキャビティ4内への溶融樹脂Mの射出に先行して起動されており、溶融樹脂Mの先端部が一対の透明体11、12の間に流入すると、該先端部で起こっている発泡状況が高速度カメラ16で連続して撮影される。   As described above, the molten resin M is injected from the hot runner through the gate into the cavity 4 and flows to the periphery of the cavity 4 while foaming at the tip. The light source 13 and the high-speed camera 16 constituting the in-mold observation apparatus 10 are activated prior to the injection of the molten resin M into the cavity 4 described above, and the tip of the molten resin M is a pair of transparent bodies. 11 and 12, the foaming situation occurring at the tip is continuously photographed by the high-speed camera 16.

本実施形態においては、照明光の入射側の透明体11の前面側に赤色系の透明板17を配置しているので、照明光に含まれる短波長成分が除去される。これによって、観察に有害な散乱光が低減し、その分、高速度カメラ16で撮影された映像(撮像)の鮮明度が向上する。また、高速度カメラ16の前面に偏光板18を配置しているので、キャビティ4内の発泡に伴って生成する球晶や気泡による散乱光に含まれる特定の偏光のみが高速度カメラ16に取込まれ、これによって散乱光の大部分が除去され、その分、高速度カメラ16で撮影された映像(撮像)の鮮明度が向上する。この結果、透明度が高い非晶性の樹脂はもちろん、透明度が低い結晶性の樹脂であっても厚さ方向の内奥部まで鮮明に可視化され、明瞭に発泡挙動を観察できるようになる。なお、偏光板18は、できるだけ鮮明な映像が得られるように回転方向に位置決めする。   In the present embodiment, since the red transparent plate 17 is disposed on the front surface side of the transparent body 11 on the illumination light incident side, a short wavelength component contained in the illumination light is removed. Thereby, scattered light harmful to observation is reduced, and the sharpness of the video (imaging) taken by the high-speed camera 16 is improved accordingly. Further, since the polarizing plate 18 is disposed in front of the high-speed camera 16, only the specific polarized light included in the scattered light due to the spherulites and bubbles generated with the foaming in the cavity 4 is taken into the high-speed camera 16. As a result, most of the scattered light is removed, and the sharpness of the video (imaging) taken by the high-speed camera 16 is improved accordingly. As a result, not only an amorphous resin having a high transparency but also a crystalline resin having a low transparency can be clearly visualized in the depth direction in the thickness direction, and the foaming behavior can be clearly observed. The polarizing plate 18 is positioned in the rotation direction so that a clear image can be obtained as much as possible.
