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

L'invention vise à perfectionner une soupape de ventilation (8), notamment pour ventiler un moule (5) destiné à la fabrication d'isolateurs type parapluie (1), de manière à éviter une déformation préjudiciable du corps moulé lors de l'extraction du moule (5). A cet effet, la soupape de ventilation (8) est constituée d'un carter (8.2) en forme d'aiguille, sur une face frontale duquel un orifice de soupape (8.5) est disposé et sur une autre face frontale duquel un corps de soupape (8.3) est monté amovible dans le prolongement axial du carter de soupape (8.2).
