DK73092A - PROCEDURE FOR INSTALLING A CASTING FORM EQUIPMENT IN A BLOCKING MACHINE, AND A CASTING MACHINE AND PREPARING EQUIPMENT FOR USE THEREOF - Google Patents

Abstract

In concrete block making machines a mould 8 divided into cells is used, and an overlying counter plate 12 with pressure foot plates 16, which can be pressed down in order to compress the concrete mass in the casting cells 10 and to expel the cast concrete fabrications by lifting the mould. The mould 8 is fixed to bottom carriers 24 and the counter plate 12 to an overlying carrier head 6 and accurately centred in relation to one another, which calls for great accuracy when forming holes for clamping bolts, in the same way that clamping of the counter plate is difficult to perform. In the invention a direct pre- centring of the counter plate 12 in the mould 8 is performed, using distance pieces 52, and so that all moulding equipment 8, 12 is inserted into the intermediate space between the carrier head 6 and the mould carrier 24, following which the mould is fixed to the latter. In the insertion a "fluid" engagement is established between interacting holder parts 44, 46 on the top of the carrier head and, after fixing of the mould, pressure cylinders 48 are actuated to draw the holder parts 46 of the carrier head up for clamping of the counter plate in the centred position. The distance pieces are then removed and the equipment can be put into operation. Fitting of the counter plate can thus be easily performed and it is possible to work with very rough tolerances. <IMAGE>
