Abstract
PURPOSE: To provide a reinforced exhaust hole by burying a metal plate with an exhaust hole fastened with bolts to a metal die and with multiple bolt holes in a synthetic resin tank by rotation molding and then removing both the bolts and the resin of the opening part.
CONSTITUTION: Bolts are inserted into bolt holes 3 of a metal plate 1 and nuts are screwed up into a metal mold 6 on its inner surface. Then, powder synthetic resin is thrown into the metal mold 6 and heated. A tank is formed by rotation molding. A clearance is formed by nuts 5 between the metal plate 1 and the metal mold 6, filled with the synthetic resin, and the metal plate 1 and the nuts 5 are inserted. When molding is finished, the bolts are removed, the mold is taken out of the tank, the synthetic resin which blocks an exhaust hole is opened. A hose 7 or a blocking plate 8 is clamped by screwing the bolts 4' into the above-mentioned nuts 4.
