本発明は補強板材、例えば合板を備えた成形品
の成形方法の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the method for forming molded articles with reinforcing plate material, for example plywood.

泡となつて発生し、成形品内に散在して外観を損
うばかりでなく強度的にも問題となつていた。 Conventionally, the molding method for molded products equipped with reinforcing plate materials such as plywood has been to place plywood of a desired size on the molding surface of a male mold on which glass fiber has been laid, and then place glass fiber mat on top of it. A female mold is then fitted onto the male mold, and then a synthetic resin is injected between both molding surfaces to form a predetermined molded product. However, because the injected resin comes into direct contact with the plywood placed on the molding surface of the male mold, residual air in the plywood's holes generates bubbles, which are scattered inside the molded product and spoil the appearance. However, strength was also a problem.
本発明は上記欠点を解消する補強板材を備えた
成形品の成形方法の提供を目的とするものであ
る。 The object of the present invention is to provide a method for molding a molded article equipped with a reinforcing plate material that eliminates the above-mentioned drawbacks.
以下、本発明の実施例を図面に基いて説明す
る。 Embodiments of the present invention will be described below with reference to the drawings.
図中、1,2は夫々雄雌型を示し、この雄雌型
1,2の夫々の接触部分には、成形品である例え
ば浴槽Aの外面を形成する凹部5ならびに浴槽A
内面を形成する凸部6が形成され、その両凹凸部
5,6の対向面を成形面aとなしている。 In the figure, reference numerals 1 and 2 indicate male and female molds, and the contact portions of the male and female molds 1 and 2 include a recess 5 that forms the outer surface of a molded product, for example, a bathtub A, and a recess 5 that forms the outer surface of a bathtub A, for example.
A convex portion 6 forming the inner surface is formed, and the opposing surface of both the concave and convex portions 5 and 6 serves as a molding surface a.
そして、上記雄型1の成形面aに添わしめてガ
ラス繊維マツト3を敷設する。 Then, a glass fiber mat 3 is laid along the molding surface a of the male mold 1.
而る後にそのガラス繊維マツト3を添わしめた
浴槽A底壁7裏面上に樹脂で包被した補強板材4
を載置する。 After that, a reinforcing plate material 4 covered with resin is placed on the back side of the bathtub A bottom wall 7 to which the glass fiber mat 3 is attached.
Place.

は完成する。 The reinforcing plate material 4 serves as a reinforcing part for the bottom wall 7 of the bathtub A, etc., and is formed of plywood, and is coated in advance with polyester resin or NC-finished with polyester resin to form a coating 8. Smooth out the wood grain. Next, a glass fiber mat 3 is placed so as to cover this reinforcing plate material. Then, the female mold 2 is placed on the male mold 1 on which the reinforcing plate material 4 is placed.
The molds are matched, polyester resin is injected through the injection hole 9, and the molds are released after a certain period of time to complete the molded product.

説明は成形品が浴槽Aである場合について述べて
いるが、浴槽Aにのみ本発明の成形方法は適用さ
れるのではなく補強部材4を備えた成形品ならば
あらゆるものを対象としている。 Therefore, since the reinforcing member 4 such as plywood is covered with polyester resin in advance to crush the grain of the plywood, even if the resin is injected, residual air remaining in the grain of the plywood does not become bubbles. Although the above explanation describes the case where the molded product is the bathtub A, the molding method of the present invention is not applied only to the bathtub A, but can be applied to any molded product provided with the reinforcing member 4. There is.

非常に大である。そして成形品の歩留りは著しく
向上し、その経済的効果は非常に大である。 As described above, the present invention involves placing a reinforcing plate material covered with resin on the molding surface of a male mold on which glass fibers are laid, covering the reinforcing plate material with a glass fiber mat, and then The female mold is fitted into the mold, and then a synthetic resin is injected between the two molding surfaces to form the desired molded product, so even if the injection resin is injected, the wood grain of the reinforcing plate will be crushed by the enveloping film beforehand. Because of this, the residual air in the wood grains does not form bubbles in the walls of the molded product, and it does not impair the appearance or weaken the strength, which has a great practical effect. In addition, the yield of molded products is significantly improved, and the economic effect is very large.
依つて所期の目的を達成し得る。 Thus, the intended purpose can be achieved.
