Device for blow molding containers

A device for blow molding containers, provided with a supporting frame for at least one station for blow molding preforms in order to obtain containers, said blow molding station comprising two lateral bodies and a bottom which are adapted to provide by blow molding at least one container, at least one of said two lateral bodies being movable on command by virtue of means for cyclic opening and closing, with respect to said supporting frame, about an articulation axis which is substantially parallel to an axis of said at least one container, kinematic connection means being provided for kinematic connection between said at least one movable lateral body and said bottom which are adapted to determine cyclically a movement of said bottom along a movement direction that is substantially parallel to said articulation axis, said means for cyclic opening and closing comprising an actuation body which is supported by a connecting linkage configured to be moved with respect to said supporting frame about a pivoting axis which is substantially parallel to said articulation axis, said connecting linkage being kinematically connected to said at least one movable lateral body and being connected, by virtue of a connection assembly, to a contoured body configured to move, with respect to said supporting frame, along a substantially rectilinear movement trajectory, said contoured body defining a cam-like profile configured to be engaged by at least one engagement element supported by said bottom, wherein said connection assembly comprises an actuation appendage which is integral in rotation with said connecting linkage about said pivoting axis, said actuation appendage supporting an abutment body which engages slidingly in a sliding seat which is integral with said contoured body, said sliding seat being extended along a sliding direction which is incident with respect to said movement trajectory and is substantially perpendicular with respect to said pivoting axis.
