Abstract
A mold made of steel and intended for manufacturing tubular objects by a centrifugal casting concrete method is formed of two semicylindrical shells having longitudinal flanges to which locking wedges are welded. The locking wedges provided on the two opposing flanges have oblique surfaces cooperating with each other. The oblique surfaces of the locking wedges extend over a plane of separation between two flanges when the mold is in a closed position.
Claims10
A mold for manufacturing tubular objects in accordance with a centrifugal casting concrete method, comprising at least two mold shells which are openable and closeable to each other, each shell having a longitudinal flange extending along an axis of elongation of the mold, the longitudinal flanges of two shells being parallel to each other and opposing each other at two sides of the mold;
- clamping means on said flanges for clamping said shells to each other and including a plurality of locking wedges rigidly connected to said flanges and projecting outwardly therefrom and arranged in pairs on two opposing flanges so that the locking wedges of each pair are interengageable with each other in a comb-like fashion upon a relative displacement of said shells in the direction of said axis, the locking wedges of each pair having oblique surfaces facing each other and cooperating with each other so that the oblique surfaces of the locking wedges of each pair extend in a plane of separation between two shells when the latter are in a clamped position.
