密着性よく形成し得る複合物品の成形方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a composite article in which a molded member and an elastic sealant are integrated, and a molding method, and particularly relates to a composite article in which a molded member and an elastic sealant are integrated, and in particular, an elastic seal is applied to a molded member made of various existing materials. The present invention relates to a method for molding a composite article that can be formed using a simple molding process and with good adhesion.

のふた、栓等があげられる。The composite article according to the present invention refers to a composite of various molded members such as plastics and metals and an elastic sealant, and specifically includes various automobile parts, such as oil pans, hand covers, instrument covers, tail lamps, etc. Alternatively, the lids and stoppers of various containers can be mentioned.
この種の複合物品は従来、シール材と被成形部材とを別

していた。Conventionally, this type of composite article is made by manufacturing the sealing material and the molded member separately and then combining them into a terra assembly.

しかし、この方法では、組み合わせに手間がかかり、傷
つきやすく、密着性に劣り、さらに、シール材と被成形
部材とのシール面精度の影響により充分なシール性が得
られず、かつシール材を手板から打ち抜く際に材料ロス
が生じる等の問題があった。However, this method takes time and effort to assemble, is easily damaged, and has poor adhesion.Furthermore, sufficient sealing performance cannot be obtained due to the influence of the precision of the sealing surface between the sealing material and the part to be molded, and the sealing material cannot be used by hand. There were problems such as material loss when punching from the blank.

、量産性に乏しい等の欠点があった。In addition, a method of applying a liquid sealant to the sealing surface of the molded part using a robot or the like and curing the adhesive has also been put into practical use, but this method has low shape accuracy of the applied bead and also has a small degree of freedom in shape. Furthermore, there were other drawbacks such as it took a long time to cure and was not suitable for mass production.

報参照）。Therefore, as a method to improve the drawbacks of these known techniques, a molding machine equipped with a pair of molds that can be replaced with each other is used, a plastic member to be molded is molded in one of the molds, and then A method is known in which an elastic sealing material is molded on the sealing surface of the plastic member to be molded using the other mold (see Japanese Patent Laid-Open No. 60-52322).

新規に設計する物品には適するが、既存の被成形部材に
対してシール材だけをあとから一体成形することは不可
能であるのみならず、被成形部材がプラスチック成形物
であるという制限もある。In this method, the part to be molded is also molded at the same time, so it is suitable for newly designed products, but it is not only impossible to integrally mold only the sealing material on the existing part to be molded. However, there is also a restriction that the member to be molded is a plastic molded product.

解決されていなかった。In order to improve this, in the method described in JP-A-60-237267, liquid rubber is applied to the sealing surface of the molded member, covered with a covering mold, cured, and demolded to obtain a composite molded product. However, with this method, it is difficult to completely release the air inside the molding cavity.
For this reason, molding problems such as the tendency to form voids and the tendency to form flakes if the coating amount is too large have not been sufficiently solved.

物品の成形方法を提供することにある。Therefore, the purpose of the present invention is to form an elastic sealing material into a molded material made of various existing materials through a simple molding process, quickly and precisely, with good adhesion, and furthermore, without causing material loss. The object of the present invention is to provide a method for molding a composite article made of a material to be molded and a sealing material, which improves the drawbacks of the various conventional techniques described above.

、硬化させることを特徴とする。In order to achieve the above-mentioned object, according to the present invention, a mold is placed over the sealing surface of a molded member having a sealing surface to form a sealing material on the sealing surface. In a method for molding a composite article of a sealing material, a groove is formed on at least one of the sealing surface or a contact surface of a mold that contacts the sealing surface, and a primer layer is formed on the sealing surface, The method is characterized in that a mold is placed over the sealing surface to form a cavity with a groove in these contact areas, and a sealing material is injected into this cavity and cured.

First, a silane coupling type primer is applied to the sealing surface 2 of the head cover 1 to form a primer layer in advance.6 Next, with the mold 4 and the receiving mold 3 open (not shown),
After suspending the oil pan 1 therein, both were closed and silicone resin was injected into the cavity 8 in the contact portion 7 formed by the contact between the sealing surface 2 and the contact surface 5. At this time, when the temperature of the mold 4 was maintained at 150 to 200[deg.] C., the silicone resin was cured into an elastomer in a short time, forming the sealing material 12 shown in FIG. This sealing material 12 was tightly adhered to the sealing surface 2 due to the presence of the primer layer. After curing, when the mold was opened and the oil pan 1 was taken out, a composite article A in which the oil pan (2) and the sealing material 12 were integrated was molded by one molding machine in a short time and with simple operations. (Fig. 8) At this time, of course, the molding accuracy of the sealing material 12 was good,
The molding shape had a high degree of freedom and there was no loss of material. Furthermore, the physical properties of the molded silicone elastomer were excellent and were no different from those of ordinary silicone heat-curing type silicone rubber.
