An employed rear mold is comprised of a plurality of mold pieces. The plurality of mold pieces include a first mold piece which forms a first partial internal surface of the internal surface of the rear mold along the entire circumference of the internal surface, and a second mold piece which is located axially forward of the first mold piece and forms a second partial internal surface of the internal surface of the rear mold along the entire circumference of the internal surface. Releasing the molded body includes starting to move the first mold piece rearward in relation to a rear molded portion, and, subsequently to starting to move the first mold piece, starting to move the second mold piece rearward in relation to the rear molded portion, thereby disassembling the rear mold into the plurality of mold pieces.

A method for making reconstituted limestone blocks includes using a batching plant to make a mixture comprising crushed limestone and cement. The mixture may additionally include water and an additive, such as a plasticizer. The batching plant has been modified to be compatible with the mixture. Next, the mixture is transferred from the batching plant to a mobile stamping machine having a mold box, a hopper, and a feed apparatus configured for transferring the mixture from the hopper to the mold box. Finally, the mobile stamping machine is activated so that the mobile stamping machine forms a construction block by transferring the mixture from the hopper to the mold box, depositing the construction block out of the mold box, and then moving to a next location. The mobile stamping machine is configured to produce approximately 100 construction blocks per hour.

A construction apparatus for forming modular construction components is disclosed. The construction apparatus comprises a first shell piece and a second shell piece that define an interior chamber defining a space for receiving a moldable material. The construction apparatus further comprises a separation device to move the first shell piece and the second shell piece from a closed configuration to an open configuration. The construction apparatus further comprises one or more cores within the interior chamber, one or more pins extending within the interior chamber, and one or more retaining plates for retaining the pins on the first shell piece. The interior chamber may be filled with the moldable material in the closed configuration and the moldable material may be cured. The construction apparatus may be shifted to the open configuration by the separation device and the pins and retaining plates may be used to extract the molded block from the first shell piece and/or second shell piece.
