摘要： Apparatus to practice the method of forming foam molded articles without the defects caused by incompletely mixed reactants in the mold cavity is provided. A mixing chamber bounded by a sidewall portion having injection apertures, an outlet aperture which communicates with the mold cavity and a first ejector piston displaceable within the bore of the mixing chamber is provided. Opposite said outlet aperture is a second ejector piston which is retracted at the start of the mold filling operation to provide a receiving chamber in the mold wall. As the mold filling proceeds, this piston is displaced towards the mold cavity until its end surface forms a planar surface with the mold wall. Optionally, this piston may be displaced into the mold cavity to eject the molded article.

摘要： A process is provided for introducing mixed foamable reactants to a mold. The process involves introducing the reactants into a mixing chamber through injection apertures in its side wall portion. The mixing chamber has an outlet aperture communicating with the cavity of the mold. Prior to introducing the reactants into the mixing chamber, a displacement piston having a smaller cross-section than the mixing chamber is inserted into the outlet aperture of the mixing chamber so that the injection apertures communicate with the mold cavity by means of a generally annular passage.

摘要： An apparatus for mixing and molding a chemically foamable reaction mixture is comprised of a mold with a mixing chamber which has its outlet aperture in a wall of the mold and a displacement piston mounted in the opposite wall. An ejector piston is displaceable within the mix chamber and may be so channelled as to serve as a control piston. This ejector piston is displaceable from a position wherein the injection apertures lie between it and the mold cavity to a position wherein its end surface is flush with the mold wall. The displacement piston is so mounted that it may extend across the mold cavity and intrude into the outlet aperture of the mixing chamber. This displacement piston has a diameter smaller than the diameter of those portions of the mixing chamber into which it protrudes so that when this piston is within the mixing chamber an annular cavity is formed between it and the side walls of the mixing chamber. It is withdrawable to a position flush with the mold wall it protrudes through. This piston may comprise a hollow sleeve and a core which together form a cavity when the sleeve is disposed in the mixing chamber. This piston may be mounted in a mold wall insert which can be moved toward the opposite mold wall to locally decrease the mold cavity width. The mix chamber and displacement piston may also be mounted in opposite walls of a sprue system which communicates with a mold cavity or mold cavities.

Control electronics are provided for controlling the metering units. The controls comprise at least one adjustable control frequency generator for generating signals to be fed to the electro-hydraulic linear amplifiers to control the movements of the metering pistons. A first signal path is provided for conducting signals to at least one of the electro-hydraulic linear amplifiers from a control frequency generator and a second signal path is provided for conducting the control frequency generator signals to all other electro-hydraulic linear amplifiers via an adjustable frequency reducer.
