Improvements in injection molding machines for thermoplastics, essentially characterized by the fact that the moving plate moves on guides by mechanical movement, transferred through a non-rotating spindle, attached to its back, whose spindle is displaced by a bearing-nut or rotating sleeve-nut on a plate of the bedplate, by effect of a drive received from an electric driven motor, and comprising in the moving plate portaamoldes or at the front end of the spindle a housing for a piston, which in the end of the advance stroke of the mold plate receives a hydraulic impulse, so that the moving part of the mold is driven in a first phase mechanically by low pressure through the spindle, and in a second phase hydraulically by high pressure to through the piston.
