1. Mold conveyor comprising a mold inlet area and a mold outlet area, comprising
a frame having mounted therein a supporting grille for supporting a plurality of molds in positions that are moved forward successively, a clamping mechanism which can move longitudinally with respect to the supporting grille and which comprises respective longitudinal clamps arranged on opposite sides along the supporting grille, at least one of the clamps being transversely movable by a plurality of actuators between a clamping position in which the clamps can hold the blocks against one another and a release position in which the clamps do not hold the molds, a reciprocating mechanism for moving the clamping mechanism forward when the clamps are in their clamping position and for moving the clamping mechanisms backward when the clamps are in their release position, wherein the clamps comprise a pair of delivery clamps arranged in the outlet area of the mold conveyor; the reciprocating mechanism comprises a push device arranged in the outlet area of the mold conveyor, the push device comprising respective lug elements articulated to the delivery clamps by means of respective connecting rods for pulling on the clamp and the push device being connected to actuation means providing reciprocating movement to the push device; the push device is a push carriage connected to the actuation means by means of a linear push system comprising at least one linear push element comprising a driving element connected to the actuation means and arranged in an area upstream of the inlet area of the mold conveyor, and a longitudinal push bar connecting the driving element to the push carriage and extending linearly below the supporting grille; the push carriage is guided horizontally in a supporting structure to perform a horizontal forward and backward movement. |
