Drain shafts moulding with two junction sockets - with cylindrical mould core and two-part cylindrical mould wall

摘要

The apparatus is used for moulding drain shafts with two junction sockets it comprises a cylindrical mould core (1) and a coaxial cylindrical mould wall consisting of two relatively rotatable halves (2a, 3a) which overlap on both sides. Each mould wall half has a socket insert (8) for forming a junction socket, and one of them is fitted with a third socket insert (23). Pref. one of the two halves consists of two rigidly releasably connected portions, one of which bears the socket insert (8) while the other (22) has no socket insert or is provided with the third socket insert. The apparatus provides greater variability with respect to the number and angular spacing of the joint sockets to be formed.
