Abstract: An exemplary mold is disclosed for impregnating a prefabricated condenser core (C) of a high voltage bushing with a liquid resin and includes two mold modules movable against each other and shaped to form an axially symmetric mold cavity. The mold forms a column of cylindrical design, in which the at least two mold modules are arranged on top of each other. A first of the two mold modules can be executed as a hollow cylinder. Two opposing front faces of the two mold modules and a circular O-ring arranged between the two opposing front faces form a first sealing interface of the metal mold. Such a mold can have a very efficient sealing system and allow high pressures to be applied to the liquid resin and a beneficial forming of the condenser core in a device in which the resin is cured according to a specified temperature profile.

Abstract translation: 公开了一种用于用液体树脂浸渍高压套管的预制冷凝器芯（C）的示例性模具，并且包括可彼此相对移动并成形以形成轴向对称模腔的两个模具模块。 模具形成圆柱形设计的列，其中至少两个模具模块布置在彼此的顶部。 两个模具模块中的第一个可以作为中空圆柱体执行。 两个模具模块的两个相对的前表面和设置在两个相对的前表面之间的圆形O形环形成金属模具的第一密封界面。 这样的模具可以具有非常有效的密封系统，并且允许在液体树脂中施加高压，并且在根据特定温度分布固化树脂的装置中有利地形成冷凝器芯。
