Abstract (en)
[origin: EP0050819A2] A mold with hydraulic opening and closing for the casting of concrete blocks with four diverging frustoconical elements, comprises a reinforced stationary base and three tilting forms pivoted to said base and each moved by a corresponding hydraulic jack. Three tilting covers are also provided for closing three of the four end openings between the forms, and fast screw tightening means between said forms and said covers, as well as jig locators and dowel pins for centering the various mobile parts of the mold one in respect of the other. The three hydraulic jacks controlling the movement of the tilting forms are controlled by a common hydraulic gearbox.
