The present invention relates to a structure of a molded product formed by using the same.

Description of the Related Art Conventionally, as a method for inexpensively and easily manufacturing a lightweight member such as a circular or polygonal frame in a ceiling-mounted luminaire, urethane foam or the like is molded on a mold such as silicon rubber. The method of molding a desired member by injecting the hard foam synthetic resin material, and foaming and hardening the hard foam synthetic resin material is used.
However, when a molded product formed by simply foaming and curing a rigid foam synthetic resin material is in the form of a thin plate, if a shearing force acts on its thickness, its durability is low and it is easy to It had the drawback of causing rupture.

成されていた。Therefore, in order to improve durability against shearing forces acting in parallel, it has been considered to incorporate a reinforcing material such as a hard resin vertically, that is, in the longitudinal direction of the members. For example, in the circular frame body in the ceiling-mounted lighting fixture, urethane foam before foaming is injected into the circular frame, and a reinforcing material made of hard resin is arranged concentrically with the frame in the frame. After that, by placing a lid on the mold and foaming urethane foam in the closed space formed by the mold and the lid, the reinforcing material is concentrically enclosed with the circular frame. A circular frame body was formed.

点があるものであった。However, in the above-mentioned conventional one, since the reinforcing material arranged in the mold is not fixed in the mold, hard foam such as injected urethane foam is formed. As the synthetic resin material is foamed, it is pressed in the upper surface direction inside the mold, and the pressing force is not uniform on the entire surface inside the mold,
Due to the difference in the pressing force, there is a drawback that the reinforcing material does not become parallel to the frame body itself, or the reinforcing material itself becomes corrugated inside the frame body. That is, in this case, since the reinforcing material is not perpendicular to the shearing force applied to the frame itself in the vertical direction, the reinforcing material cannot exhibit sufficient durability, and the frame itself easily tears. It had the drawback of occurring.

てなるものである。To this end, a rigid foam synthetic resin material is poured into a mold, and a reinforcing material is detachably suspended in parallel and detachably from a lid of the mold by a plurality of fixing members. A lid having is installed on a mold, and in the space closed by the lid and the mold, the hard foam synthetic resin material is foamed so as to include the reinforcing material. For this purpose, a plurality of screws with the crowns protruding in the same direction and the same length in the vertical direction with respect to the reinforcing material are screwed into the reinforcing material at appropriate intervals, and the reinforcing material is reinforced in the vertical direction with respect to the reinforcing material. On the lower surface of the lid of the mold made of silicon rubber, locking nails that are made to project substantially in the same direction as the protruding direction of the screw with the material side as the base portion are arranged at appropriate intervals on the reinforcing material. The screw crown is brought into contact with the engaging member. After the reinforcing material is engaged with the nail, the mold into which the rigid foam synthetic resin material is injected is closed by this lid, and the rigid foam synthetic resin material is foamed so as to enclose the reinforcing material in the closed space. After the material is hardened, the engagement between the lid and the locking nail is released, and the tip of the locking nail protruding on the surface of the molded product is removed, or the upper surface of the lid of the mold The reinforcing material is engaged with the lower surface of the lid body at a desired fixed interval from the lower surface of the lid body by a plurality of locking screws protruding further to the lower surface and arranged at appropriate intervals, and the lid body is used to form the hard foam synthetic resin material. Is closed, and in the closed space, the hard foam synthetic resin material is foamed so as to enclose the reinforcing material, and after the material is cured, the engaging screw is removed from the upper surface of the lid body. This allows the reinforcement to be parallel and straight to the frame. Those formed by manner is included.

となる。With the above structure, even when the reinforcing material installed in the mold is pressed in the upper surface direction when the hard foam synthetic resin material is foamed, the reinforcing material itself is against the lid of the mold. Since it is fixed to the lid so as to have a constant distance, the reinforcing material can always be kept parallel to the mold, and the pressing force in the upper surface direction during foaming becomes uneven. However, since the reinforcing material is fixed to the lid body by the plurality of fixing members, it is possible to prevent the reinforcing material from being deformed into the corrugated shape due to the pressing force due to foaming.

等を充填することが望ましい。As a result, the reinforcing material (3) becomes the lid (8).
It will be held in the formwork (1) in a state of being suspended in parallel with. After that, when the urethane foam (9) is foamed while being pressurized, the reinforcing material (3) and the locking screw (10) are foamed to be contained in the urethane foam (9) that has been expanded and hardened. . At this time, even if a pressing force is unevenly applied to the reinforcing material (3) due to the foaming action of the urethane foam (9), the locking screw (10) is attached to the reinforcing material (3) in places. Are arranged, and they are screwed and engaged with the lid body (8), so that the reinforcing material (3) can be supported against the pressing force thereof, and therefore the reinforcing material (3) itself. Is suspended in the lid (8), that is, is enclosed in the urethane foam (9) that is hardened in a straight line parallel to the form (1). Then, after the urethane foam (9) is sufficiently cured, the locking screw (10) is removed from the upper surface of the lid (8) to separate the lid (8) from the mold (1), The urethane foam (9) hardened from 1) is extracted. The distal end side of the locking screw (10) is incorporated into the urethane foam (9) as the urethane foam (9) is foamed, but the upper surface of the lid body (8) is removed when the lid body (8) is detached. By removing the locking screw (10), it is also removed from the inside of the cured urethane foam (9). Therefore, in the molded frame body (2), the locking screw (9) is removed. It is desirable to fill the space with a filler, etc., because a space will be generated in the screwed portion and the shearing resistance of the frame body (2) itself will be reduced.

れた効果を有するものである。As described above, according to the present invention, when a reinforcing material is incorporated in the molding of a member made of a hard foam synthetic material, the reinforcing material can be attached in parallel and linearly with respect to the lid and can be detached. By fixing, with a simple structure, it is possible to improve the shearing force resistance of the member itself by holding the reinforcing member parallel and linear to the member itself even after molding, especially for the reinforcing material. In addition to using screws and nails in the vertical direction and holding the screws and the like in the molded member, the reinforcing material acts two-dimensionally to increase the shear strength of the member itself. It has an excellent effect that it can be further improved.
