Concrete pipe manufacturing mould - has socket locking devices coupled together and to central locking mechanism

摘要

Concrete component manufacturing mould is partic. for concrete pipes, and has a sleeve split in the lengthwise direction and a central locking mechanism on the outside to close the gap thus formed before pouring. A lower socket locking mechanism has a number of locking devices spaced round the socket end of the mould, and swinging on axes parallel to that of the mould between the release and working positions. The locking devices (5, 6, 7) are coupled to each other and to the central locking mechanism, and an eccentric shaft (18) can in turn be coupled to them. This shaft can be extended to the socket end of the mould, having a lever (19) coupled by links (20, 21, 22) to the locking devices.
