Mold assembly for forming a seal unit |
摘要 |
A mold assembly for making fluid seals. The mold includes an outside diameter surface on a fixed part and a seal flange support surface on another portion of the fixed part. A seal casing with a shouldered mounting flange having major and minor outside diameters and a radial flange is positioned in the fixed mold part. A movable mold member includes an upper, outer cylindrical surface for engaging the inside surface of the casing major diameter to form a flash barrier which moves during mold closure. Both the fixed mold part and the movable mold part include inwardly directed surfaces defining the mold cavity; the flange support is apertured for the elastomer to flow from the seal body-forming part of the cavity to the heel gasket-forming part of the cavity. The heel-forming cavity part lies between the lower part of the inside surface of the mold and the outer surface of the casing minor diameter.
