Abstract
An injection mould for manufacturing fittings ( ) from thermoplastics, which fittings are provided on the inside with at least one annular groove ( ), includes a separable outer mould ( ) and a mould core ( ) which can be pushed into the outer mould ( ). A complementary mould bead for forming the annular groove is configured on the mould core ( ). The injection mould has a cavity which is formed in the area of the annular groove ( ) of the fittings ( ) by a plurality of segments ( ′) that can be assembled together. The outside surface of the portion of the cavity that forms the area of the fitting ( ) surrounding the annular groove ( ) is partly formed by the separable outer mould ( ) and partly by a mould ring ( ) connected to the mould core. The separating surface ( ) of the mould ring ( ) which forms a seam between the mould ring ( ) and the outer mould ( ), terminating at the fitting ( ), has a portion adjacent to the cavity that forms an angle of less than 45° with respect to the longitudinal axis of the mould core ( ).
