Abstract (en)

[origin: CA2298678A1] The aim of the invention is to provide an improved ventilation valve (8), especially for ventilating a mould (5) in the production of umbrella type insulators (1), so that harmful deformation of the moulded body can be avoided during removal from the mould (5). This is achieved by providing the ventilation valve with a rod-like or pin-shaped housing (8.2) with an orifice (8.5) on one of its front faces and by providing a valve body (8.3) on the other front face which is detachably mounted in an axial extension of the valve housing (8.2).
