〔産業上の利用分野〕
本発明は射出成形方法に関する。さらに詳しくは、貫通
孔を有する樹脂成形品と貫通孔を有さない樹脂成形品と
を同一型内で成形する射出成形方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an injection molding method. More specifically, the present invention relates to an injection molding method for molding a resin molded product having a through hole and a resin molded product not having a through hole in the same mold.
自動車の樹脂製パンパなどにおいては、全体の形状は同
一であるが、車の仕様によりフォグランプなどを設置す
るための貫通孔を設けたものと、このような貫通孔を設
けないものとが必要になるばあいがある。Plastic pumps for automobiles have the same overall shape, but depending on the car's specifications, some have through holes for installing fog lamps, etc., and others do not have such holes. There is a possibility.
従来、かかる貫通孔を有する樹脂成形品と貫通孔を有さ
ない樹脂成形品とを成形するばあいは、それぞれ専用の
成形型を用いて成形するのが一般的である。Conventionally, when molding a resin molded product having such a through hole and a resin molded product having no through hole, it has been common to use dedicated molds for each.
しかし、専用の成形型を製作するのでは成形型の製造費
用が高くつく。However, manufacturing a dedicated mold increases the manufacturing cost of the mold.
この点に鑑みて、本発明は同一型内で貫通孔を有する樹
脂成形品と貫通孔を有さない樹脂成形品とを成形する射
出成形方法を提供することを目的とする。In view of this point, an object of the present invention is to provide an injection molding method for molding a resin molded product having a through hole and a resin molded product without a through hole in the same mold.
すなわち本発明は、同一型内で貫通孔を有する成形品と

填して成形することを特徴とする射出成形方法に関する
。That is, the present invention provides a pair of molds in which a molding space is formed between the molded products and a molded product without the through holes in the same mold. A nest installed on one side of the mold, a first position where the tip end surface of the nest is substantially flush with the inner surface of the one mold, and a gap large enough to prevent molten resin from flowing into the inner surface of the other mold. and a means for moving the nest forward and backward so that the nest can assume a second position in which they are substantially in contact with each other, and when producing a molded product that does not have a through hole, the The molding space is filled with molten resin and molded with the distal end surface moved to the first position, and when a molded product having a through hole is to be molded, the nest is moved so that the distal end surface thereof is moved. The present invention relates to an injection molding method characterized in that the molding space is filled with molten resin and molded while the molding space is moved to take the second position.
入れ子をその先端面が前記他方の成形型の内面にほぼ当
接する位置にくるように移動させ、その状態で射出成形
すれば、貫通孔を有する成形品かえられ、一方入れ子を
その先端面が前記一方の成形型の内面とほぼ同一面にな
る位置にくるように移動させ、その状態で射出成形すれ
ば貫通孔を有さない成形品かえられる。If the insert is moved so that its tip end surface is almost in contact with the inner surface of the other mold, and injection molding is performed in that state, a molded product having a through hole can be replaced. If it is moved to a position where it is almost flush with the inner surface of one of the molds and injection molded in that state, a molded product without a through hole can be obtained.
（発明の効果〕
前記のごとく、貫通孔を有する成形品と貫通孔を有さな
い成形品とを同一型内で成形できるって、両成形品をそ
れぞれ専用の型を用いて成形するばあいにくらべて成形
費用を低減できる。(Effect of the invention) As mentioned above, a molded product with a through hole and a molded product without a through hole can be molded in the same mold, and if both molded products are molded using their own molds, Molding costs can be reduced compared to
また貫通孔を有する成形品をうるばあいに入れ子の先端
面を他方の成形型の内面に完全に当接させないため他方
の成形型の当該内面にキズが付かず、そのため同一型内

型の当該内面に対応する成形品表面に外観不良が生じな
い。In addition, when molding a molded product with a through hole, the tip of the nest is not brought into complete contact with the inner surface of the other mold, so the inner surface of the other mold is not scratched. Even if a molded product that does not have the molded product is molded, no appearance defects will occur on the surface of the molded product that corresponds to the inner surface of the other mold.

The core (3) is moved forward and backward so as to be in a position where it substantially contacts the inner surface (2a) of the core (3) and a position where it is substantially flush with the inner surface (3a) of the core (3). Although the means for moving the nest (5) in this manner is not particularly limited, for example, in the embodiment shown in FIG. 1, a hydraulic device is used. That is, the core (3) has a passage (7) perpendicular to the direction of movement of the nest (5) and reaches below the cavity (6), and a rod-shaped piece (7) extending from the bottom of the nest (5).
8) is adapted to project into the passageway (7'). On the other hand, the hydraulic system (g)) is installed so that its piston rod 01) extends into the passage (7), and an inclined member a2) having an inclined surface (12a) is attached to the tip of the piston rod (old). It is being When the hydraulic system is driven and the piston rod 01) is extended, the tip of the rod-shaped piece (8) of the nest (5) touches the inclined surface (12) of the inclined member 02).
a), so that the nest (5) slides up into the cavity (
2) in the direction of the inner surface (2a). On the other hand, when the piston rod 01) is shortened, the tip of the rod-shaped piece (8) slides down the inclined surface (12a) of the inclined member 02), and the nest (
5) moves away from the inner surface (2a) of the cavity (2). The insert (5) is stopped at a position where the tip end surface (5a) of the insert (5) substantially contacts the inner surface (2a) of the cavity (a) or is substantially flush with the inner surface (3a) of the core (3). To do this, for example, use a stopper to adjust the stopping position of the piston rod.

For example, in order to mold a bumper, the tip surface (5a) of the nest (5) is not brought into complete contact with the inner surface (2a) of the cavity ('2J), as shown in FIG.
) and the inner surface (2a) of the cavity (a) to have a slight gap (G) to prevent the molten resin from flowing in. When it comes into complete contact with the inner surface (2a) of
If a) is scratched and, as a result, a molded product without a through hole is molded using the same mold, a defective appearance will occur on the surface of the product at the portion corresponding to the surface in contact with the insert (5). This tendency is particularly noticeable when grains are provided on the surface of the product. However, the tip surface (5a) of the nest (5)
By providing a small gap (a) between the inner surface (2a) of the cavity (2) and the inner surface (2a) to prevent the molten resin from flowing in, the inner surface (2a) is prevented from being scratched. If the gap (9) is too large, the resin will flow into the gap (0), causing the occurrence of flakes. From this point of view, it is preferable that the gap (0) be about 0.01 to 0.2 mm.
When 0 is at this level, no flaking occurs under normal injection molding conditions, and there is no problem in terms of appearance quality.
貫通孔を有さない成形品をうるばあいは、入れ子（５）
をその先端面（５ａ）がコア（３）の内面（３ａ）とほ
ぼ同一面となる位置に移動させ、射出成形すればよい。If you are using a molded product that does not have a through hole, use the nest (5).
may be moved to a position where its distal end surface (5a) is substantially flush with the inner surface (3a) of the core (3), and then injection molded.
その際入れ子（５）の先端面（５ａ）とコア（３）の内
面（３ａ）とが完全に同一面となるのが理想的である。In this case, it is ideal that the tip end surface (5a) of the nest (5) and the inner surface (3a) of the core (3) are completely flush with each other.
先端面（５ａ）とコア（３）の内面（３ａ）との間に段
差があると、樹脂の流れに影響が出て、その結果入れ子
（５）の先端面（５ａ）と反対側の製品表面に艶ムラが
生じることとなる。しかし実際には入れ子（５）の先端
面（５ａ）とコア（３）の内面（３ａ）とを完全に同一
面とすることは困難である。If there is a step between the tip surface (5a) and the inner surface (3a) of the core (3), the flow of resin will be affected, and as a result, the product on the opposite side of the tip surface (5a) of the nest (5) will This results in uneven gloss on the surface. However, in reality, it is difficult to make the tip end surface (5a) of the nest (5) and the inner surface (3a) of the core (3) completely flush with each other.
本発明においては、前記段差が生じても、その段差が一

That is, when the tip end surface (5a) of the nest (5) protrudes into the space (4) as shown in FIG. 3, the step (81) is 0.1 mm or less, and as shown in FIG. The tip surface (5) of the nest (5)
Step (S) when a) is recessed into the space (6)
If l) is 0.3 mm or less, the uneven gloss will be within the allowable range and there will be no problem in terms of appearance quality. It is a good thing to keep the steps (Sl), (Sl) within the above range by using the moving means of the nest (5) as described above.
