ABSTRACT OF THE DISCLOSURE An improved apparatus for blow molding and conditioning synthetic resin containers, comprising two end walls, to which the permanent molds that jointly constitute one forming mold are locked in a removable fashion, these being movable synchronously between an extrusion and a blowing station, powered concurrently in opposite directions by the operating devices. Into the form- ing mold, at the extrusion station, is extruded a tubular element of synthetic resin having notable plastic deformation character- istics which, by compressed air being flown therein, is formed into a corresponding synthetic resin container. To each end wall is locked a bush coupled to a tubular shaft to provide for longi- tudinal translation but not rotation, and the latter is united, in a position equidistant from the bushes, to a coupling sleeve, fixed to a saddle, underneath the said shaft, and slides on guides having a downward inclination from the extrusion to the blowing station. The tubular shaft contains part of the devices for operating the end walls or is an integral part thereof.
