ABSTRACT:
A molding machine is disclosed which can be used in the manufacture of concrete building elements. A method for the molding of concrete modular units using the disclosed concrete molding machine is also provided. The molding machine is constructed of vertical walls joined to form a single outer frame which is moveable up and down by means of expandable joints such as pneumatic or hydraulic cylinders which allow positioning and vibration of the outer frame. To said outer frame are attached horizontally expandable joints which support at least two mold sides which can be placed in abutment by the action of the expandable joints so as to form the continuous sides of a mold. The bottom side of the sequentially assembled mold is provided by a metal plate to which the aforesaid sides are lowered or attached. Detachment of the mold sides from the said outer frame as a unit allows support of the uncured concrete by the mold sides as an assembled mold during subsequent transport from the molding machine to curing ovens. The outer frame may then be used to assemble another set of mold sides immediately and is not prevented from use until the cementitious material which filled a prior set of mold sides cures sufficiently for the removal of the mold sides Provision is also made for the support of articles to be cast internally in the building elements by means of members attached at one end to the vertical walls of said outer frame, wherein the members may be extended horizontally thru apertures in the mold sides to within the confines of the various molds by a means of expansion and contraction which forms an integral part of the said members.
