JIG FOR TREATING INNER SURFACE OF ELASTIC MOLDING MOLD

摘要

PURPOSE:To obtain a Jig for expanding an elastic molding mold turned inside out by introducing a gas into the mold, readily making a coating film on the surface. CONSTITUTION:A jig for inner surface treatment of an elastic molding mold 12 consists of a ring-shaped body 1 having an L-shaped cross-sectional shape, a disklike or cylindrical inner block 5 which is engaged with the body 1 and has a through hole 6 at the central part and a ring-shape cap 8 which is geared with the inner block 5, can be connected to the body 1 and has a GAMMA-type cross- sectional 1 shape. The body 1 is linked to the cap 8, the elastic molding mold 12 turned inside out is fixed to the bottom of the inner block 5 by the body 1 and a gas is introduced in this state through the through hole to expand the elastic molding mold.
