Moulding device for concrete moulded articles

摘要

The invention relates to a moulding device for concrete moulded articles, in particular lower parts of sewer shafts, with an outer formwork 1 and an inner formwork 2 which enclose a mould cavity 3 corresponding to the shape of the moulding, can be moved relative to the outer formwork 2 in an axially delimited manner by lifting means and can be fixed in a mould-operation position in the outer formwork 2 by locking means. To reduce in particular the manual work for form-stripping the moulding, which is necessary in the case of known moulding devices, while retaining a possible relative movement of the inner formwork 1 before removal of the outer formwork, the lifting and locking means of the mould device are formed by hydraulic lifts 16 which can be locked in the mould-operation position of the inner formwork (Fig. 1). <IMAGE>
