BLOWING OR STRETCH-BLOWING MACHINE FOR BOTTLES MADE OF POLYMER MATERIAL
A machine for blowing or stretch-blowing bottles or containers made of a polymer material includes molds movable on a transport system. Each mold includes a front, back, and bottom with a first and second half-molds hinged about a hinge axis and a base. Each of the molds includes a mechanism for synchronized actuation of the half-molds and the base independently from the machine's motor, to cyclically form with shaped portions, a closed cavity for receiving a preheated preform and to allow expansion by blowing or stretch-blowing the preform inside the cavity to obtain a bottle or container. The base is wedge-shaped with a horizontal closing surface facing the bottom of the mold, and an inclined surface. The actuation mechanism includes a wedge-shaped element having a surface inclining towards the front of the mold. The inclined surfaces of the base and of the wedge-shaped element are) being slidingly coupled.
