Abstract
Die Seitenwände (3) der Form (1) weisen Aussparungen (10) auf, in denen jeweils ein Formkern (9) zur Anbringung von Vertiefungen (7) an den Aussenseiten eines mit dieser Form hergestellten Betonformsteines angeordnet ist. Die Formkerne (9) sind um eine horizontale, parallel zu den Formwänden verlaufende Schwenkachse (13) an den Aussenseiten der Form schwenkbar gelagert. Über einen Schwenkantrieb (19,20), der beispielsweise aus einer Schrägschlitzsteuerung besteht, sind die Formkerne (9) durch die Aussparung (10) hindurch in das durch die Formwände (3) begrenzte Formnest (2) hinein- und zurückschwenkbar. Dabei dienen die inneren Begrenzungskanten der Aussparung (10) als Abstreifer, die beim Zurückschwenken des Formkerns (9) eine Selbstreinigung aller mit dem Beton in Berührung gekommenen Flächen des Formkerns bewirken. Dadurch werden die Zeitintervalle für die Reinigung der Formkerne erheblich verlängert und eine saubere und glatte Oberfläche des fertigen Betonformsteines (5) gewährleistet. The side walls (3) of the mold (1) have recesses (10), in each of which a mold core (9) is arranged for making depressions (7) on the outside of a concrete block made with this mold. The mold cores (9) are pivotally mounted on the outer sides of the mold about a horizontal pivot axis (13) running parallel to the mold walls. The mold cores (9) can be pivoted back and forth through the recess (10) into the mold cavity (2) delimited by the mold walls (3) by means of a swivel drive (19, 20), which consists, for example, of an oblique slot control. The inner boundary edges of the recess (10) serve as wipers which, when the mold core (9) is pivoted back, cause self-cleaning of all surfaces of the mold core that have come into contact with the concrete. This considerably extends the time intervals for cleaning the mold cores and ensures a clean and smooth surface for the finished concrete block (5).
