A molding machine for the production of polygonal structural elements, e.g. concrete squares, comprises an assembly of vertical plates disposed between a pair of end members of a support and defining generally flat mold cavities of the shape desired with respective bottom members and lateral gates.

A molding machine for the production of polygonal structural elements, e.g. concrete squares, comprises an assembly of vertical plates disposed between a pair of end members of a support and defining generally flat mold cavities of the shape desired with respective bottom members and lateral gates. The lateral gates are hinged to the rectangular bottom members at the ends thereof and are interconnected by respective bars so that all of the lateral gates along each side of molded cavities can be swung outward into release position and indeed into mold-closing positions by laterally shiftable carriers on the end members of the support.

A molding machine for the production of polygonal structural elements, comprising: a support having a pair of mutually spaced end members; a pair of elongated mutually parallel rectangular horizontal bottom plates disposed between said end members each adapted to define the bottom of a respective mold cavity having the configuration of the structural elements, said bottom plates having ends along narrow sides of the respective rectangles; respective rectangular vertical plates disposed between said end members and defining opposite walls of adjacent mold cavities, one of said vertical plates serving as a common member separating said mold cavities from one another; jack means on one of said end members and connected to the vertical plate proximal thereto for displacing said vertical plates relative to said members from a molding position, wherein the vertical plates of each mold cavity are spaced apart by a distance corresponding to the width of the respective bottom plate into a release position in which elements molded in said cavities can be discharged, said vertical plates having increased spacing from one another in said release position; means for connecting one of the vertical plates of each mold cavity to the respective bottom plate thereof; respective lateral gates hingedly connected to each of said ends of each of said bottom plates and swingable between closed positions wherein said lateral gates are spread away from edges of the element formed in the respective mold cavity; shiftable respective bars extending between said members and connected to the lateral gates of the mold cavities; and means on said end members for shifting said bars to displace said gates between said mold position and said release position, and each of said bars being guided in said end members by respective grooves for arcuate movement.
