Description of the Related Art Conventionally, silicone rubber has many excellent physical properties such as heat resistance, cold resistance, weather resistance, electrical insulation, water resistance, oil resistance, and chemical resistance. It is widely used as a seal material between an oil pan of an internal combustion engine requiring oil resistance and a crankcase.

・インプレス・ガスケット（ＣＩＰＧ）法である。There are roughly two types of sealing methods using silicone rubber. One advance using a mold of silicone rubber, is molded Impress gasket (MIPG) method of forming a gasket by injection molding, the other one, mating surface of the oil pan that require sealing Apply room temperature curable silicone rubber in a bead shape,
This is a cured impress gasket (CIPG) method in which a seal portion is formed by being left in air as it is.

On the other hand, the latter CIPG method has an advantage that productivity can be remarkably improved because work can be performed at the assembly site of the object to be sealed without restriction on time and place. However, the silicone rubber applied in a bead form generates irregularities or wrinkles on the surface and makes the sealing surface non-uniform, so that a sufficient sealing effect cannot be obtained.

The surfaces are brought into contact with each other to form a smooth shape and heat-cured. For this curing, at least the surface is sufficient,
The interior is not necessary. When the mold 5 is removed,
Since the entire surface of the liquid silicone rubber S is formed into a smooth and convex sealing material 3, if the lid 2 ′ is put on the sealing material 3, perfect adhesion can be obtained and sealing can be performed. In addition, since the silicone rubber flows in using the concave groove 6, it is possible to dispose the silicone rubber in an accurate position, not only to improve the sealing accuracy, but also to reduce the positional deviation during use or when the lid 2 'is repeatedly opened and closed. Since it does not occur, it has excellent durability.

Sealing was performed in the same manner as in the above example except that the container was heated and hardened for one minute, and as a result of measuring the air pressure at which air began to leak from the sealing part when the inside of the container was pressed, the result was 2.5 kgG / cm 2. Was.

ことができる。According to the present invention, a concave groove is formed on at least one of the mating surfaces, a thermosetting silicone rubber is cast into the concave groove in a bead shape, and the surface is heated to form a concave shape. In order to cure smoothly by contacting the concave surface of the mold, CI
Although the PG method is used, a sealing effect equal to or higher than that of the MIPG method can be obtained. In addition, since the silicone rubber is filled by using the concave groove, the silicone rubber can be arranged at an accurate position, thereby improving the accuracy and improving the durability in which the sealing effect is not changed even by repeated use. be able to.
