Premolded sleeve mold for extra high voltage cable joint

摘要

PURPOSE: A mold of a pre-mold sleeve for a super-high pressure cable connecting box is provided to easily remove a mold from a molded sleeve by injecting compressed air to the inside of the mold. CONSTITUTION: A mold comprises an outer cavity mold(1), an inner core mold(2) formed in the center of the outer cavity mold, and an upper plate(4) and a lower plate(5) covering the end portion of the outer cavity mold. Air inject holes(3) are formed in the upper and lower portions of the outer cavity mold. If an insulating portion(7) of a sleeve starts to cool, an air inject pipe is connected to the air inject hole. Compressed air is injected from the air inject hole to the inside of the mold. Thus, the outer cavity mold is easily removed from the insulating portion of the sleeve.
