Abstract
A method of and apparatus for injection molding of injection molded parts containing imbedded inserts, especially injection molded parts formed of a thermosetting plastic, comprising an injection molding machine equipped with an injection nozzle located at an injection molding position and a divided injection mold having hollow mold compartments or cavities. The injection mold is operatively connected with the injection nozzle and one of the cooperating mold halves is connected with a stationary mold support plate and the other mold half with a movable mold support plate displaceable towards and away from the stationary mold support plate. At an insert element-filling position removed from the injection molding position there is provided means for delivering and introducing the insert elements into the hollow mold compartments. According to the invention, at least two similar mold halves are arranged upon one mold support plate, each of these mold halves is alternately shiftable, transverse to the direction of movement of the movable mold support plate, from a first position, corresponding to the injection molding position, where it is located opposite the other cooperating mold half into a second position, corresponding to the insert element-filling position, where it is located opposite the means for delivering and introducing the insert elements into the hollow mold compartments.
