Abstract

PURPOSE: A mold for reinforced plastic pipes capable of easy mold releasing, comprising axes movable in the radial direction provided in the radial through-holes of the wall of a tubular material, set pieces attached to the inside ends of the axes, and an outer split cylindrical body consisting of an elastic material.
CONSTITUTION: The set pieces 4 and the axes 2 are moved outward by feeding a pressurized fluid, by inserting a bar into a mold, or by expanding an air bag under pressure from the inside. The split cylindrical body 3 is expanded to enlarge the diameter of the cylindrical body 5 of an elastic material to a given one. A molding material, e.g. continuous glass filaments impregnated with a resin, is wrapped around the body 5 and cured to remove the pressurized fluid, the bar, or the expansion of the air bag. The body 5 is shrunk to the original state due to its elasticity, thus removing the mold from the molded reinforced plastic pipe readily.
