この発明は、金属板等の補強材が樹脂成形体に埋設され
た補強樹脂成形体の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for manufacturing a reinforced resin molded body in which a reinforcing material such as a metal plate is embedded in the resin molded body.
合成樹脂製の成形体を補強するため、内部に金属板等の
補−強材を埋設することは知られている。It is known to bury a reinforcing material such as a metal plate inside a molded body made of synthetic resin in order to reinforce it.
例えば、実開昭６４−３３８３１号公報には、ばね性を
有する平板状の芯材を埋設した合成樹脂製軒樋吊り具が
提案されている。For example, Japanese Utility Model Application Publication No. 64-33831 proposes a synthetic resin eaves gutter hanger in which a flat core material having spring properties is embedded.
ところで、上記公報には、合成樹脂製軒樋吊り只の製造
方法については全く記載がないが、このような合成樹脂
製軒樋吊り具を製造するには、この吊り具の形状に対応
した型窩を有する射出成形型を用い、この型窩内に溶融
樹脂を射出充填することにより吊り具を成形する方法即
ち射出成形法によるのが一般的であると思われる。By the way, the above publication does not contain any description of the method for manufacturing synthetic resin eaves gutter hangers, but in order to manufacture such synthetic resin eave gutter hangers, a mold corresponding to the shape of the hanger is required. It seems to be common to use an injection molding mold having a cavity and to mold the hanger by injecting and filling the mold cavity with molten resin, that is, the injection molding method.
しかし、前記の合成樹脂製軒樋吊り具にあっては、内部
に補強材（平板状の芯材）が埋設された構造であり、こ
のような構造体を得るには、補強材の全周を覆うように
樹脂を射出充填しなければならないが、補強材を型窩内
の所定箇所に型窩面から浮いた状態で保持することはで
きないので、実際には何らかの保持体で補強材を型窩内
に保持した状態で溶融樹脂を型窩内に射出充填すること
になる。However, the synthetic resin eaves gutter hanger described above has a structure in which a reinforcing material (a flat core material) is buried inside, and in order to obtain such a structure, it is necessary to remove the entire circumference of the reinforcing material. The reinforcing material must be injected and filled to cover the mold cavity, but since it is not possible to hold the reinforcing material in a predetermined position within the mold cavity while floating above the mold cavity surface, in reality, some kind of holder is used to hold the reinforcing material in the mold. The molten resin is injected and filled into the mold cavity while it is held in the cavity.
従って、得られた成形体−（吊り具）には、この保持体
も成形体に埋設されてしまうので、射出成形のサイクル
毎に保持体を金型にセントしなければならず煩瑣であっ
た。Therefore, this holder is also embedded in the obtained molded body (hanging tool), so the holder must be inserted into the mold every cycle of injection molding, which is cumbersome. .
また、保持体の端面が成形体の表面に露出することにな
り、外観も良くなく、金属補強体の場合には腐食し易い
という問題があった。In addition, the end face of the holder is exposed to the surface of the molded body, resulting in a poor appearance and, in the case of a metal reinforcing body, being susceptible to corrosion.
一方、このような問題を避けるために、成形後に、この
成形体から保持体を取り外し、その空隙を樹脂等で埋め
ることも考えられるが、その作業は極めて煩瑣であると
ともに、後から埋めた部分の体裁、強度は十分なもので
なかった。On the other hand, in order to avoid such problems, it is conceivable to remove the holder from the molded body after molding and fill the gap with resin, etc., but this work is extremely cumbersome and the parts filled later The appearance and strength were not sufficient.
この発明の補強樹脂成形体の製造方法は、上記の点に鑑
み、成形体内に埋設する補強体を型窩内で保持するため
の保持体を成形体内に残すことなく、しかもその保持体
は金型にセットされたままで連続して使用できるように
することにより、補強樹脂成形体を容易に製造できるこ
とを目的とする。In view of the above points, the method for producing a reinforced resin molded body of the present invention does not leave a holder in the molded body for holding the reinforcing body embedded in the molded body in the mold cavity, and the holder is made of metal. It is an object of the present invention to easily manufacture a reinforced resin molded article by allowing continuous use while it is set in a mold.

可能にされた杆体の先端が該補強材の両面を押圧するこ
とにより保持されるものであることを特徴とし、このこ
とによって、前記目的が達成される。The method for manufacturing a reinforced resin molded article of the present invention is to inject and fill a mold cavity with molten resin while the reinforcing material is held at a predetermined position in the mold cavity, thereby producing a molded body in which the reinforcing material is embedded. A method for manufacturing, wherein the reinforcing material is used when the mold is closed;
It is characterized in that the tip of the rod that protrudes into the mold cavity and is retractable from within the mold cavity as the resin is injected and filled is held by pressing both sides of the reinforcing material, thereby: The above objectives are achieved.
この発明方法において、補強材としては、成形体の主体
を構成する樹脂を補強できる強度の優れた金属、繊維強
化樹脂等より製せられた板状或いは成形体とほぼ類催形
状のもの等が用いられる。In the method of this invention, the reinforcing material may be a plate-like material made of metal, fiber-reinforced resin, etc. with excellent strength capable of reinforcing the resin that constitutes the main body of the molded product, or a material having a shape similar to that of the molded product. used.
この発明の補強樹脂成形体の製造方法は、前記したとお

樹脂圧により保持杆が順次後退し、型窩面まで後退する
。従って、補強材の全周に溶融樹脂が行き渡り、補強材
が内部に埋設した成形体が成形される。Since the method for producing a reinforced resin molded article of the present invention has the configuration described above, the reinforcing material is held at a predetermined position in the mold cavity of the mold by pressing it from both sides by the holding rod until the injection filling of the resin begins. As the mold cavity is filled with resin, the holding rod is sequentially retracted by the pressure of the resin and retreats to the surface of the mold cavity. Therefore, the molten resin spreads around the entire circumference of the reinforcing material, and a molded body in which the reinforcing material is embedded is formed.

れる。The fixed mold 1 and the movable mold 2 are closed and the reinforcing member 9 is attached to the holding rod 4.5.
When the mold cavity 6 is held at a predetermined position (FIG. 1), molten resin is injected and filled into the mold cavity 6 through the sprue 3 from the nozzle 10 of the injection molding machine. As the molten resin is injected and filled into the mold cavity 6, it enters the hole 91 of the reinforcing material 9, and the tip part 42 of both holding rods 4.5.
．． 52 comes to be pressed by this resin pressure. This resin pressure overcomes the spring force of spring 7.7, and both retaining rods 4.
5 is its base 41.51 and each mounting plate 11.21
Filling of the resin is completed by retreating to the surface of the mold cavity 6 so as to fill the gap 8.8 between the mold and the mold, and the molded body A, which is a gutter hanger, is formed.

製造できる。Since the method for manufacturing a reinforced resin molded article of the present invention has the above-described configuration, the reinforcing material is held at a predetermined location in the cavity of the mold by being pressed from both sides by the holding rod until filling with resin begins. As the mold cavity is filled with resin, the resin pressure causes the holding rod to retreat to the surface of the mold cavity. Therefore, the reinforcing material is properly held at a predetermined location and embedded within the molded object, so that a resin molded object in which the reinforcing material is embedded can be easily produced.
