製造に好適な方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method of molding a fluid material such as synthetic resin, cement, or plaster by pressing it in a mold, and at the same time embedding embedded members such as nuts and bolts. According to
Regarding a method for manufacturing a molded article having an embedded member,
In particular, the present invention relates to a method suitable for manufacturing a molded article using a fluid material with high flow resistance, which is a mixture of synthetic resin, cement, plaster, etc. with various reinforcing fibers, aggregates, fillers, etc. as a molding material.

Conventionally, various types of molding using fluid materials have been known. For example, molding devices using cement are disclosed in Japanese Patent Publication No. 49-7045, Japanese Patent Publication No. 54-20209, and the like. Note that these publications disclose apparatuses or methods for manufacturing molded products whose main component is cement.
This does not disclose a technique for embedding metal fittings such as bolts and nuts in a molded product.

ける方法は、成形後の成形物に金具取付穴をあ
け、或いは成形時に金具取付穴を成形し、その穴
に金具を挿入し接着材等で固定する方法が一般的
である。 Depending on the molded product, it may be necessary to embed appropriate metal fittings. Conventionally, the common method for attaching metal fittings to a molded product is to drill a metal fitting mounting hole in the molded product after molding, or to form a metal fitting mounting hole during molding, insert the metal fitting into the hole, and fix it with adhesive, etc. It is.
しかし、この方法では成形工程と金具取付工程
の二工程が必要となり、コストアツプにつながる
という問題があつた。
However, this method requires two steps: a molding step and a metal fitting attaching step, which poses a problem in that it leads to an increase in costs.

となり、クリアランスを多くすると成形材料の流
動圧が高いため、材料が隙間に入り込んで金具が
抜けなくなる。この問題は、特に成形材料の流動
性が悪い場合に顕著に生じる。 To solve this problem, it is sufficient to embed metal fittings at the same time as molding. However, when implementing the method of embedding the metal fittings at the same time as molding, it is necessary to hold the metal fittings at a predetermined position within the mold during the molding operation, and there is a problem in holding the metal fittings. In other words, in the method of providing protrusions or recesses in the mold and fitting the metal fittings into them, demolding becomes difficult if the clearance at the fitting part is small, and if the clearance is increased, the flow pressure of the molding material is high, so the material is forced into the gap. It gets stuck in there and the metal fittings cannot be removed. This problem occurs particularly when the molding material has poor fluidity.
埋設金具を型に固定する方法として磁石の吸着

使用する場合には、高圧プレスする必要があり、
材料の流動圧が高いため磁石の吸着力では金具を
保持することが不可能となる。 Japanese Patent Publication No. 61-34380 discloses a method using the attraction force of a magnet as a method of fixing a buried metal fitting to a mold. However, when using molding materials with poor fluidity, high pressure pressing is required.
Due to the high flow pressure of the material, it is impossible to hold the metal fittings with the attraction force of the magnet.

り、作業性が悪いという問題もある。 In addition, when burying a metal fitting that penetrates the molded product, if the metal fitting is attached to the lower mold, for example, the molding material may get caught between the upper end of the metal fitting and the upper mold, resulting in poor product quality or There are problems such as excessive force acting on the part that contacts the upper end of the metal fitting, causing the upper die to wear out. Furthermore, when embedding a metal fitting with a through hole such as a nut, there is a problem that the molding material gets stuck inside the nut, and to avoid this, it is necessary to temporarily plug the upper end of the metal fitting to prevent molding material from entering. Therefore, there is also the problem of poor workability.

The present invention has a pin hole communicating with the inner surface of the mold in one of two molds that are movable relative to each other so as to approach and separate from each other, and an engagement for holding an embedded member at the tip of the pin hole. A holding pin with a joint is mounted so as to be movable in the axial direction, and the holding pin further includes:
A device is used in which a hydraulic cylinder mechanism for moving the holding pin in the axial direction is connected, and the embedded member is held at the tip of the holding pin, and the holding pin is moved forward by the cylinder mechanism. The embedded member held at the tip of the holding pin is held in the forward position, the molding material is supplied between the two molds, and then one mold is relatively moved closer to the other mold, and the holding pin is moved closer to the other mold. Pressing the molding material while pressing the tip of the embedded member with the inner surface of the mold on the side where the pin is not provided and pushing the holding pin into the mold against the pressing force of the cylinder mechanism,
Next, the gist is a method for manufacturing a molded product having an embedded member, which is characterized by opening two molds and demolding the molds.
本発明の実施に当たつては、二つの型を上下に

According to the above manufacturing method, the molding material supplied between the two molds is pressure-molded by closing the two molds, and at that time, the embedded member is held by the holding pin provided in one mold. The tip of the embedded member is pressed against the inner surface of the other mold, and the holding pin is pushed into the mold against the pressing force of the cylinder mechanism, so both ends of the embedded member are always kept close to the holding pin and the mold. The molding material is in contact with the inner surface, and when the molding material fills around the buried component, the buried component does not move from its predetermined buried position, and the molding material is not caught between the end surface and the mold inner surface or holding pin. In other words, the molding material does not adhere to both ends of the embedded member, and a molded product with a good appearance in which the embedded member is reliably penetrated can be obtained. In addition, when the two molds are closed and pressure molded, the pressing force that acts on the buried member is the pressing force of the cylinder mechanism connected to the holding pin, so there is no possibility that excessive pressing force will act on the buried member. This also reduces wear and tear on the inner surface of the mold that comes into contact with this buried member. Furthermore, when an embedding member having a through hole is embedded through the embedding member, the tip of the embedding member is closed by the inner surface of the mold, so that it is possible to prevent molding material from entering without temporarily plugging the embedding member.

FIG. A pin hole 10 communicating with the inner surface of the mold is formed in the lower mold 4, and a holding pin 11 is provided in the pin hole 10 so as to be movable in the axial direction. An engaging portion 11A that fits into the through hole 2A of the embedded member 2 and holds it is formed at the tip of the holding pin 11. This engaging portion 11
A does not need to fit tightly into the through hole 2A of the buried member 2, and may have some looseness. This makes it easy to attach and remove the buried member 2. Further, a piston rod 13 of a hydraulic cylinder mechanism 12 for moving the holding pin in the axial direction is connected to the rear end of the holding pin 11. In this embodiment, an air-operated cylinder mechanism 12 is used.
次に、上記構成の装置による成形手順を説明す

終的な位置よりも上昇した位置となつている。(2) Move the trolley 3 to the position shown in Figure 2A and position the lower mold 4 under the GRC mortar feeder 6. Thereafter, or before that, the hydraulically actuated cylinder 12 is actuated to advance the retaining pin 11 to the advanced or raised position shown in FIG. 1A, and to engage the embedded member 2 with the retaining pin 11. At this time, the buried member 2 is at a position higher than the final position with respect to the lower mold 4.

It descends while being pushed down against the pressing force by the cylinder mechanism 12. At this time, since upward pressing force (for example, about 7 kg/cm 2 due to air) is constantly acting on the holding pin 11 by the cylinder mechanism 12, the buried member 2 is pressed against the inner surface of the upper mold 8 with the necessary contact pressure. It is also kept pressed against the holding pin 11 with the necessary contact pressure.

嵌合をゆるくしても支障はない。(6) With the lower end of the side mold 9 in close contact with the lower mold 4, the upper mold 8 continues to descend, pressing the GRC mortar and causing it to flow, filling the space surrounded by the upper mold 8, side mold 9, and lower mold 4. (See Figure 2C). On this occasion,
The GRC mortar flows and fills the surroundings and the vicinity of the upper and lower ends of the buried member 2, but as mentioned above, the upper and lower ends of the buried member 2 are strongly pressed against the upper mold 8 and the holding pin 11, so during this time, the GRC mortar Mortar does not enter, nor does it enter into the through hole 2A of the embedded member 2. Therefore, there is no need to temporarily plug the tip, that is, the upper end of the through hole 2A, and there is no problem even if the engagement portion 11A and the through hole 2A are loosely fitted.

防止される。(8) After that, the piston of the cylinder mechanism 12 linked to the holding pin 11 is lowered, the engaging part 11A of the holding pin 11 is pulled out from the through hole 2A of the buried member 2, and then the upper mold 8 is raised. As shown in the figure, the molded product 1 is removed from the lower mold 4 held by the side mold 9. Note that the operation of pulling out the holding pin 11 from the buried member 2 does not necessarily have to be performed before the upper mold 8 rises, and as the molded product 1 moves up away from the lower mold 4, the holding pin 11 is removed from the buried member 2. It may be possible to exit automatically.
However, if the clearance between the engaging portion 11A of the holding pin 11 and the through hole 2A of the buried member 2 is small and the fit is tight, a large force will be applied when pulling out the holding pin 11 from the buried member 2. It is preferable to lower the holding pin 11 and pull it out from the buried member 2 while the molded product 1 is being sandwiched between the upper mold and the lower mold. In this way,
This prevents the molded product from being deformed when the holding pin is pulled out.

As explained above, in the present invention, a holding pin movably provided in one mold (for example, the lower mold) of two molds that are opened and closed for molding is advanced by a cylinder mechanism, and the holding pin is moved forward by a cylinder mechanism. The embedded member held at the tip is held in the forward position, and the molding material is supplied between one mold and the other mold, and then the two molds are closed, and the inner surface of the mold on the side without the holding pin is The molding material is pressure-molded while pressing the tip of the buried member and pushing the holding pin into the mold against the pressing force of the cylinder mechanism, so the molding material fills around the buried member. When doing so, both ends of the buried member are strongly pressed by the mold and the holding pin, so that the molding material is not caught between both ends of the buried member and the mold or the holding pin. It is possible to obtain a molded product with a good appearance in which the embedded member is reliably penetrated without the molding material adhering to the molding material. Furthermore, when the two molds are closed by pressure molding, the pressing force that acts on the buried member is the pressing force of the cylinder mechanism connected to the holding pin, so that no excessive pressing force is applied to the buried member. Wear of the mold portion that comes into contact with this buried member is also reduced. Furthermore, when a buried member having a through hole is buried through the hole as shown in the example, there is no need to temporarily plug the tip of the buried member to prevent molding material from entering, resulting in improved work efficiency. There is.
