A mold for manufacturing interlocking, dry-cast concrete retaining wall blocks in an upright orientation comprises a mold box comprising two side walls joined to end walls to define a mold cavity, a top face, and a substantially open bottom face. Partitions configured to define a space between adjacent blocks or a space between a block and a side of the mold box extend parallel to the side walls of the mold box substantially from the top face into the mold cavity, to form first transverse portions of the profile of the top and bottom surfaces the blocks which do not include any undercut portion that would impede removal of the mold box in a substantially vertical direction. At least one removable insert comprises insert members which, when positioned in the mold box beneath the partitions, form remaining transverse portions of the profile of the top and bottom surfaces, the remaining transverse portions including at least one undercut portion. The insert members, when in position in the mold box for casting, are substantially in lateral alignment with respective bottom surfaces of at least some of the partitions and can be inserted and retracted through openings in an end wall of the mold box.

The invention comprises a concrete form. The form comprises a first concrete forming panel having a first primary surface adapted for forming and contacting plastic concrete and a second primary surface opposite the first primary surface; a layer of insulating material contacting and substantially covering the second primary surface of the first concrete forming panel; and an insulating blanket adjacent the first concrete forming panel. A method of using the concrete form is also disclosed.

A stacking die comprises a stacked multiple stacking plates and a side plate(s) which fixes the multiple stacking plates in a stacked state, wherein at least one or more processing object(s) is retained in a space(s) formed between the multiple stacking plates. Further, surfaces where the stacking plates and the side plate(s) abut each other are preferably tapered so that they form tapered shapes in a direction opposite to the approach direction of the side plate(s).

A pressure die casting mold for producing a casting which is part of an integral toilet having a body, a water ring, and a tank, wherein the casting, as an integral component, includes the water ring and the tank which is open on the upper side. The pressure die casting mold is composed of at least five molded parts which are interconnectable in a releasable manner, namely of a base part, two side parts having in each case one half of a front wall, a rear wall, and a cover part. The molded parts delimit a cavity which corresponds to the outer shape of the casting. A wedge element, which at least in portions delimits the inner shape of the water tank, is provided on the base part.
