- the present invention relates to an injection mold used in the method.
- the side on which the ejector pin is provided when the mold is opened (usually Is preferably left on the movable side). This is because when the molded product remains on the side where the ejector pin is provided, the molded product can be automatically taken out from the mold by the protrusion of the ejector pin, and productivity is improved.
- an ejector device for taking out a preform using an ejector piston that is injected outward by compressed air a large through hole is provided in the center of the ejector piston, and the preform is sucked from the through hole when the preform is cooled.
- an ejector device that makes it possible (see, for example, Patent Document 1).
- the preform is brought into close contact with the cylindrical bush by suction from the through-hole to cool the preform efficiently, and then the ejector piston is injected using compressed air. By doing so, the preform can be taken out from the cylindrical bush.
- An object of the present invention is to advantageously solve the above problems, and an injection mold according to the present invention includes a fixed mold and a movable mold that form a molding cavity when the mold is closed, and the fixed mold. And a material injection means for injecting a molding material into the cavity provided in at least one of the movable molds, and a mold opening provided in any one of the fixed mold and the movable mold A molded product removing means for removing the molded product from the mold later, and a vacuum suction path provided in the mold in which the molded product removing means is provided and capable of depressurizing the cavity. is there.
- the vacuum suction path for decompressing the cavity is provided on the side where the molded product removing means is provided, that is, the mold on which the molded product is to be left when the mold is opened, the vacuum suction path is opened when the mold is opened.
- the dimensions of the vacuum suction path can be designed so that the shape of the vacuum suction path does not remain in the molded product based on the viscosity and injection pressure of the molding material, the suction pressure when performing vacuum suction, and the like. That is, it can be designed so that the molten resin does not enter but the gas can pass.
- the dimension (clearance) of the connecting portion between the vacuum suction path and the cavity can be set to 0.003 to 0.015 mm, for example, preferably 0.00. 005 to 0.010 mm. If the clearance is set to 0.003 mm or more, the side on which the molded product remains when the mold is opened can be controlled more reliably.

It is preferable to be formed. In this way, if the vacuum suction path is formed using a slight gap between the ejector pin and the mold, there is no need to separately provide a hole for the vacuum suction path in the mold. Therefore, it is possible to easily manufacture an injection mold by using an existing mold without significantly remodeling. In addition, since there is no need to provide a separate hole for the vacuum suction path, the occurrence of burrs does not increase.
- the gap between the ejector pin and the die is small, the shape of the vacuum suction path does not remain in the molded product even when the molded product is manufactured using a low viscosity material such as an elastomer. Also, when vacuum suctioning the molded product in the cavity through the gap between the ejector pin and the mold, the suction force is distributed over a wide area along the outer periphery of the ejector pin. Compared to the case where the molded product is sucked, the side where the molded product remains when the mold is opened can be more reliably controlled, and burrs are generated even when the molded product is manufactured using a low-viscosity material. hard.
- the vacuum suction path is formed using the gap between the ejector pin and the mold, the space provided inside the mold necessary for advancing and retracting the ejector pin shows a buffering action during vacuum suction.

- the molded product is sucked under reduced pressure through the gap between the ejector pin and the mold, the molded product is sucked in a direction parallel to the mold approaching / separating direction (mold closing / opening direction).
- the molded product can be removed from the mold more reliably and easily as compared with the case where other molded product removing means such as an air ejector is used. This is because the ejector pin advances and retreats in the approaching / separating direction of the mold, so that the molded product is surely removed from the mold.
- the size of the clearance may be such that the molten resin does not enter but allows gas to pass through, taking into account the slidability of the ejector pin, for example, 0.003 to 0.015 mm. It is preferable that the thickness is 0.005 to 0.010 mm. If the clearance is set to 0.003 mm or more, the side on which the molded product remains when the mold is opened can be controlled more reliably. If the clearance is set to 0.015 mm or less, burrs (trace of vacuum suction) of the molded product can be controlled. Occurrence can be prevented more reliably.
- the clearance is preferably set to 0.005 to 0.010 mm from the viewpoint of improving the reliability on the side where the molded product remains and preventing the generation of burrs.
- the method for producing an injection-molded article of the present invention is a production method using the above-mentioned injection mold, and a mold closing step for forming the cavity by bringing the fixed mold and the movable mold into close contact with each other.
- the molded product When the vacuum suction path is used to reduce the pressure inside the cavity, the molded product is sucked to the vacuum suction path side in the cavity, so that the molded product is provided with a vacuum suction path by opening the mold while vacuuming as in the present invention.

- the suction pressure may be changed between the raw material injection and the mold opening.
- the vacuum suction path for decompressing the cavity is provided on the side where the molded product removing means is provided, that is, on the side where the molded product is desired to remain when the mold is opened. Therefore, the side where the molded product remains when the mold is opened can be controlled with high accuracy by performing vacuum suction of the molded product in the cavity using the vacuum suction path when the mold is opened.

Abstract
Description
なお、上記クリアランスの大きさは、エジェクタピンの摺動性を考慮した上で、溶融状態の樹脂は侵入しないがガスは通過可能な大きさとすることができ、例えば0.003~0.015mmであることが好ましく、0.005~0.010mmであることが更に好ましい。クリアランスの大きさを0.003mm以上とすれば、型開き時に成形品が残る側をより確実に制御することができ、0.015mm以下とすれば、成形品のバリ(減圧吸引の跡)の発生をより確実に防止することができる。なお、成形品が残る側の確実性の向上およびバリ発生の防止の観点からは、クリアランスは0.005~0.010mmとすることが好ましい。
本発明に係る方法に従い射出成形用金型10を用いて射出成形を行った。具体的には、真空ポンプ81でバッファータンク80内を表1に示す真空度に保持しておき、金型10を閉じた際に、例えば成形機からの型閉め信号を受けて第1のバルブ83を開き、第1のバルブ83が開いた状態(キャビティ50内の減圧吸引を行った状態)で成形材料であるエラストマーのキャビティ50への射出および冷却硬化を行った。その後、第1のバルブ83を開いた状態のまま型開きを行い、型開きを行った後に第1のバルブ83を閉じて第2のバルブ84を開き、減圧吸引を解いた状態でエジェクタピン37を用いて成形品を取り出した。ここで、成形は、射出成形機に16個の金型を設置することにより、1ショット(型閉め→材料注入→冷却硬化→型開き→成形品取り出し)あたり16個の成形品を自動で成形できるように行い、1ショットあたり20秒のサイクルタイムで行った。なお、成形時に固定型側に成形品が残った場合には、成形品の取り外しなどに2分間必要であるため、2分間のダウンタイムが発生した。そして、2時間成形を行い、固定型側に製品が残ったショット数、総ダウンタイム、生産個数を評価した。結果を表1に示す。
成形材料の射出および硬化後であって型開き前に第1のバルブ83を閉じて、第2のバルブ84を開き、減圧吸引を解いた状態で型開きを行った以外は、実施例1~6同様にして成形品の製造を試みたが、全ショットで固定型側に成形品が残ったため、自動成形を行うことができなかった。そのため、手取りで成形品の取り出しを行った場合(サイクルタイム30秒)の固定型側に製品が残ったショット数、生産個数を参考までに表1に示す。
