Abstract

A tubular pipe connector is moulded in an annular cavity between a pref. cylindrical outer mould and a centre block arranged within the outer mould. The centre block includes a stationary cylindrical part and a movable part having a frusto-conical portion around which an elastic ring is located whereby when the movable part is moved (e.g. by a pneumatic ram) towards the stationary part the ring engages a seat on the stationary part and slides along the frustoconical portion and expands radially such that it projects into the cavity and forms an internal annular channel in the pipe connector. After moulding the movable part is moved away so that the ring slides down the frusto-conical portion and contracts thereby allowing the pipe connector to be removed. A number of pref L-shaped metallic feet are posnd. with one branch between the elastomeric ring and the frusto-conical portion and the other branch extending along the radial face of the elastomeric ring which is contacted by the seat, and pref. the two branches are inclined at 90 degrees. The device is simple and allows the pipe connector to be easily removed from the mould.
