Abstract

A mould arrangement for shaft rings or the like in which the hat-shaped mould core comprises a core segment consisting of a cover portion with, adjacent thereto, a wall portion which is adapted for displacement horizontally into a closed position completing the shaped contours of the mould core and inwardly into a release position for removal of the form work. The mould core has a fit-in device for the cementing in of projecting elements, above all climbing irons, from the interior into the concrete part which is to be formed and during the shaping process. In addition to the core segment, the fitting-in device has for each climbing iron a housing, a clamping device associated therewith, and a clamping drive common to all these. Together with these parts, the core segment is detachably and exchangeably so mounted on the remainder of the mould core that it can be coupled to or uncoupled from the horizontal translatory drive. Thus, while retaining the rest of the mould core, the core segment can be exchanged for a different one. As a result the investment costs for individual mould cores are substantially reduced.

Dependent claims

A moulding apparatus for shaping concrete parts provided with a plurality of projecting elements to be cemented from inside of the concrete part into the concrete part, said moulding apparatus comprising:

a mould core having a shaped contour, a central axis, a core wall made of a plurality of wall portions, a top cover and a fitting-in device so that during shaped, the projecting elements can be fitted and cemented into the concrete part to be formed, said fitting-in device having at least one core segment forming at least one wall portion of said core wall;
a drive device for moving said core segment relative to the remaining wall portions of said mould core out of said shaped contour into a release position which permits a concrete part to be removed, and back into a closed position in which said core segment fits into said remaining wall portions of said mould core, completing said contour, said one wall portion and said remaining wall portions having mutually adjacent lateral edges whcih are substantially parallel to said central axis of said mould core;
guide members and guides located on and extending from said one wall portion and said remaining wall portions in the region of said mutually adjacent lateral edges, said guide members and guides automatically entering into a guiding engagement with one another upon insertion of said core segment, said drive device actuating two spaced-apart guide members to reciprocate in a translatory manner, and upon insertion of said core segment being automatically coupled form-lockingly in a translatory manner with one wall portion of said core segment;
and
a plurality of housings each having an associated clamping device and an associated clamping drive, one said housing being provided for each projecting element to the cemented in, said core segment together with said housings, said clamping devices and said clamping drive being detachably and exchangeably supported on said remaining wall portions of said mould core.

a mould core having a shaped contour, a central axis, a core wall made of a plurality of wall portions, a top cover and a fitting-in device so that during shaping, the projecting elements can be fitted and cemented into the concrete part to be formed, said fitting-in device having at least one core segment forming at least one wall portion of said core wall;
a drive device for moving said core segment relative to the remaining wall portions of said mould core out of said shaped contour into a release position which permits a concrete part to be removed, and back into a closed position in which said core segment fits into said remaining wall portions of said mould core, completing said contour, said one wall portion and said remaining wall portions having mutually adjacent lateral edges which are substantially parallel to said central axis of said mould core;
guide members and guides located on and extending from said one wall portion and said remaining wall portions in the region of said mutually adjacent lateral edges, said guide members and guides automatically entering into a guiding engagement with one another upon insertion of said core segment, said drive device including two translatory drives supported on said remaining wall portion of said mould core and disposed at a distance from and along side one another,
each of said translatory drives having a moving part and another part, each said guide member being rigidly attached to said moving part of a respective translatory drive and being guided along with said moving part on said another part of said respective translatory drive, said another part being rigidly mounted on said mould core, said drive device thus actuating said guide members through said translatory drives to selectively couple with said core segment to secure the mould core together;
and
a plurality of housings each having an associated clamping device and an associated clamping device, one said housing being provided for each projecting element to be cemented in, said core segment together with said housing, said clamping devices and said clamping drive being detachably and exchangeably supported on said remaining wall portions of said mould core.

a mould core having a shaped contour, a central axis, a core wall made of a plurality of wall portions, a top cover and a fitting-in device so that during shaping, the projecting elements can be fitted and cemented into the concrete part to be formed, said fitting-in device having at least one core segment forming at least one wall portion of said core wall;
a drive device for moving said core segment relative to the remaining wall portions of said mould core out of said shaped contour into a released position which permits a concrete part to be removed, and back into a closed position in which said core segment fits into said remaining wall portions of said mould core, completing said contour,
said one wall portion and said remaining wall portions having mutually adjacent lateral edges which are substantially parallel to said central axis of said mould core;
guide members and guides located on and extending from said one wall portion and said remaining wall portions in the region of said mutually adjacent lateral edges, said guide members and guides automatically entering into a guiding engagement with one another upon insertion of said core segment,
said drive device including two translatory drives supported on said remaining wall portion of said mould core and disposed at a distance from alongside one another,
each of said translatory drives having a moving part and another part, each said guide member being rigidly attached to said moving part of a respective translatory drive and being guided along with said moving part on said another part of said respective translatory drive, said another part being rigidly mounted on said mould core,
each translatory drive being a working cylinder having a continuous piston rod and a moving cylinder housing, said piston rod being rigidly mounted on said mold core, and said moving cylinder housing carrying a rigidly attached associated guide member, said drive device thus actuating said guide members through said translatory drive to selectively couple with said core segment to secure the mould core together;
and
a plurality of housings each having an associated clamping device and an associated clamping drive, one said housing being provided for each projecting element to be cemented in, said core segment together with said housings, said clamping devices and said clamping drive being detachably and exchangeably supported on said remaining wall portions of said mould core.
