PURPOSE:To dispense with the reversal of a form at the time of demolding and to easily perform demolding. CONSTITUTION:A concrete product molding apparatus is equipped with a pair of the side plates 16 attached to both side parts of a palette 13 by a clamp mechanism 14 bent outwardly at the upper parts of the molding inner surfaces thereof, the core frame 17 arranged between both side plates, the end plates 18 provided so as to be allowed to face to the end parts of both side plates, the horizontal materials 20 arranged in a horizontal direction along the outsides of the side plates and supported at both ends thereof by the end plates 18 and the arm materials 21 pivotally provided to the horizontal materials at one ends thereof and the side plates at the other ends thereof. By moving the end parts along the horizontal materials forwardly and rearwardly, the gaps between both left and right end parts of both side plates can be converted to a closed state and an opened state. When the side plates are relatively raised with respect to the end plates, both side plates are raised by the revolution of the arm materials while moved outwardly. |
