Patent attributes
An injection mold for producing, from thermoplastic plastic, fittings which have an annular groove on the inside. The injection mold includes an outer mold, divided into a first and second mold half and along a parting line, and a mold core being axially displaceable along a mold half. A complementary mold bead for forming the annular groove is formed by levers carrying ring segments. A slider, which bridges the parting plane of the outer mold and is connected to the second mold half, has guide grooves of differing obliqueness, in which there engage motionally lateral projections both of the mold core and of the actuating element. A guide, which extends the opening stroke of the mold core, is formed at a distance from the parting plane, between the slider and at least the mold core, the guide preferably comprising second, lateral projections and second guide grooves.
