A securing device comprising at least one latch (22) and at least one latch mating-element (26) are used on two mutually displaceable mold-casing segments (14, 16) to close or open a mold casing (10) used in manufacturing molded bodies, in particular concrete pipes, said device securing the mold casing (10) in a position of manufacture. The latch (22) is displaceable by means of a drive unit (24) between a locked position wherein it locks up with a latch mating-element (26) and an unlocked position wherein no locking takes place between the latch (22) and the latch mating-element (26). In the invention, the drive unit (24) can be adjusted due to relative motions between the mold casing on one hand and its manufacturing environment on the other as determined by the manufacturing procedures between a ready-to-unlock position corresponding to the locked position of the latch (22) and a ready-to-lock position corresponding to the locked position.
A mold casing (10) for manufacturing molded bodies, in particular for the manufacture of concrete pipes,
Mold casing as claimed in one of the above claims, characterized in that the drive unit (24) preferably comprises a drive rod (24) which is displaceable in the longitudinal direction of the mold casing (10).
Mold casing as claimed in one of the above claims, characterized in that a beyond-the-dead-point mechanism (28) is used to tighten the drive unit (24) as a function of its position in the direction of one of the two positions of readiness.
Mold casing as claimed in one of the above claims, characterized in that the minimum of one latch (22) consists of a pivoting latch (22) pivoting upon actuation of the drive unit (24) and in that the associated latch mating-element (26) consists of a peg (26) which is engaged from the rear by the pivoting latch (22) during said pivoting motion.
Mold casing as claimed in one of the above claims, characterized in that the latch (22) and/or the latch mating-element (26) is fitted with tapered surfaces.
Mold casing as claimed in one of the above claims, characterized in that the latch (22) and/or the latch mating-element (26) is fitted with a mechanism to adjust the tightening between the latch (22) and the latch-mating element (26) in the locked position.
Mold casing as claimed in one of the above claims, characterized in that at least one latch (22) of the securing-device is fitted with a grip portion (36) used for manual actuation.
Mold casing as claimed in one of the above claims, characterized in that several latches (22), preferably all latches (22) are driven by a common drive unit (24).
Mold casing as claimed in one of the above claims, characterized in that it comprises at least two mutually pivotably linked mold-casing segments (12, 14, 16).
