摘要： The problem of wet-cast concrete products getting stuck or being uncontrollably ejected from a flexible mold during demolding is solved by moving the flexible mold through a passage, defined by both a mold-receiving surface and a rotatable mold-support distanced therefrom, while moving an edge of the flexible mold along an unsmooth path that includes at least one sharp point.

摘要： A method for demolding concrete blocks which are cast in a resilient mold supported in a rigid frame, the mold having a top surface and at least one cavity with an opening on the top surface, which cavity holds a cured cast concrete block. The mold has two opposing edges. The demolded blocks are stacked on a collection surface. A support is positioned over the cavity and the mold, the support and the frame are inverted and positioned in demolding apparatus. After two opposing edges of the mold are engaged by the demolding apparatus, the support is withdrawn to allow the mold to sag. The blocks may release from the mold and fall onto the collection surface. If any blocks remain in the mold, a plunger mechanism is pushed against the sagging mold to release the blocks. Guide members may facilitate positioning the blocks on the collection surface.

摘要： In the moulding of cementitious articles, a flexible plastics mould e.g. of LDPE may be used to permit de-moulding of the articles e.g. by flexion of the mould. Moulds filled with hydraulically settable material may be supported in frames configured e.g. with plug and socket formations on upper and lower faces for cooperation with moulds to retain them in position and for cooperation with overlying and underlying frames to permit stacking.

摘要： An assembly for molding and demolding hardened cementitious products comprises a flexible mold and a demolding apparatus. The flexible mold has a top side with separate openings for receiving cementitious material therein for hardening thereof, an opposite closed rear side and a perimeter. The apparatus for demolding the hardened cementitious products from the flexible mold comprises a conveyor, a holding member, a clamp, and a movable member. The conveyor conveys the flexible mold. The clamp grips a portion of the perimeter. The holding member engages the mold. The movable member moves the clamp and the clamped portion of the mold about the holding member thereby disengaging the flexible mold from the cementitious material.

摘要： A form for creating a pattern in uncured concrete during a vertical column casting process includes an end wall and at least one side wall, extending from an edge of the end wall with the side wall and end wall cooperatively defining a corner therebetween. A pliable liner is attached to the end wall and the side wall and operably joins the side wall to the edge of the end wall to define a mold cavity. At least one patterned surface is formed on or in the pliable liner and is operable to form a corresponding pattern into concrete disposed in an uncured form in the old cavity. A notch is formed in the pliable liner and extends along the corner and forms a pivotable joint between the end wall and the side wall to facilitate removal of the form device from about the concrete after the concrete has at least partially cured.

摘要： A method and apparatus for forming a concrete block in form having a resilient insert forming a cavity in which the block is cast and a rigid support for the resilient insert. After the block has cured, the form is inverted. One or more areas of the insert are tethered to the support so that at least a portion of the insert can fall a short distance from the support. The weight of the cast block sufficiently deforms the insert to allow the block to fall free from the insert. When the form is again inverted to its upright position, the insert falls back into the support and returns to its original shape.
