ABSTRACT:
A composite insulator-producing lateral type molding apparatus includes a mold body constituted by a first molding unit and a second molding unit, each of said first and second molding units being provided, at an inner peripheral face, with recesses for the formation of a housing constituted by a plurality of shed portions and a axial portion connecting these shed portions, means for opening or tightening the first molding unit and the second molding unit, a pouring passage for pouring a housing-forming material into said recesses, and housing-forming material escape holes. A core member of the insulator is placed between the first and second molding units, the first and second molds are tightened, and the housing-forming material is poured into said recesses to form the housing. The first molding unit and the second molding unit extend laterally, and that the core member is laterally arranged horizontally between first and second molding units.
