本発明は螺子孔あきプレート片面へのゴムシー
ル体成形法の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved method of molding a rubber seal body onto one side of a plate with a screw hole.

要にゴムが侵入し、この侵入ゴムの除去が困難で
あり、成形能率の低下が避けられない。 When fastening the plates with screws, as shown in Fig. 1, a seal member 3' is formed and fixed on the surface of the plate 1' surrounding the screw hole 2', and the seal member 3' is formed and fixed between the bolt 4' and the screw hole 2'. may provide strict sealing properties. The molding and fixing of the seal body is carried out by setting the plate in a predetermined mold, but in the conventional molding method, rubber unnecessarily intrudes into the screw holes, and it is necessary to remove this intruded rubber. is difficult, and a decrease in molding efficiency is unavoidable.

ることを特徴とする方法である。 The method of molding a rubber seal body on one side of a plate with a screw hole according to the present invention is a method that can eliminate the above-mentioned disadvantages. A lower mold having a recess for forming a disposable rubber piece and an upper mold are provided, and the screw hole is filled on a plate placed on the lower mold so that the recess for forming a disposable rubber piece is located directly below the screw hole. Place the unvulcanized rubber material on the
This method is characterized in that the upper die is then lowered to form a piece of rubber seal that protrudes downward from the rubber seal body and the plate, and after vulcanization, the piece of rubber is removed by pulling it downward.
以下、図面により本発明を説明する。 The present invention will be explained below with reference to the drawings.

去する。 In FIG. 2, 1 is a plate (for example, made of metal) having a screw hole 2. First, a recess 51 for forming a disposable rubber piece is provided directly below the screw hole 2 of the lower mold 5b.
3 is filled with an unvulcanized rubber material 31, another unvulcanized rubber material 41 is placed on the plate 1 so as to cover the screw hole 2, and then the upper mold 5a is lowered, as shown in FIG. As shown, a rubber seal body 4 is molded and fixed on the surface of the plate 1 surrounding the screw hole 2, and at the same time the screw hole 2 is also filled to form a discarded rubber piece 3 protruding from the lower side of the plate 1. Generally, adhesive is applied to the top surface of the plate in advance, and the sealing body 4 is
to firmly adhere to the plate. The rubber material is vulcanized by pressurizing and heating in this state for a required period of time. Thereafter, the waste rubber piece 3 is removed by pulling the waste rubber piece downward as shown in FIG.
この捨てゴム片３には、突出部３０が存在する
ので、螺子孔からの捨てゴム片の除去は容易であ
り、この捨てゴム片３の除去により、螺子孔２に
不要なゴムを残存させることなく、上記シール体
を成形できる。 Since the discarded rubber piece 3 has a protrusion 30, it is easy to remove the discarded rubber piece from the screw hole, and by removing the discarded rubber piece 3, unnecessary rubber remains in the screw hole 2. The above-mentioned seal body can be molded without any process.
なお、上記において下型５ｂの凹部５１への未
加硫ゴム３の詰め込みを行わずに、未加硫ゴム４
１だけで捨てゴム片３を形成することができるの
は勿論である。 In addition, in the above, the unvulcanized rubber 4 is not packed into the recess 51 of the lower mold 5b.
It goes without saying that the disposable rubber piece 3 can be formed using only the rubber piece 1.
以上説明したとおり本発明に係る螺子孔あきプ

造し得るので、その工業的価値は高い。 As explained above, in the method of molding a rubber seal body on one side of a screw hole plate according to the present invention,
At the same time as the rubber seal body is molded, a piece of rubber protruding into the screw hole is molded, and after the molding, the piece of rubber scrap is removed.Removal of the rubber piece is easy and prevents unnecessary rubber from entering the screw hole. The rubber seal body can be molded on the surface of the plate with screw holes without adhesion, and good products can be manufactured quickly and reliably, so its industrial value is high.
