摘要： A system is disclosed for a plural component plastics reaction injection molding machine which provides continuous supply and recycling of each of a plurality of liquid components between a mixing head and separate supply tanks for the respective liquid components. The system is designed to use a portion of the respective recycle conduits of the several components as supply conduits to the head, in parallel with the normal supply conduit to the head, during periods of reaction injection taking place in the mixing head, whereby to permit the employment of smaller diameter conduits in the aforesaid portions of the system without reducing the capacity of the molding system. Further economy is achieved by design of the aforesaid portions of the conduit systems to dispose either the supply or recycle conduit concentrically within the other.

摘要： The specification describes a high pressure mixing head for producing a chemically reactive mixture for producing foam articles. An expulsion piston adapted to move in a mixing chamber with inlet ports for the reactive mixture components and with an outlet port is driven by a drive piston. In order to achieve a higher velocity of the expulsion piston in the vicinity of the inlet ports the drive piston is constructed in two parts, an inner piston part and an outer annular piston part adapted to slide on the inner piston part. At the end of the stroke the outer piston part is arrested and the inner piston part continues to move at a higher velocity, a projection at the end of the drive piston moving into a recess. At the beginning of the stroke in the other direction the projection is moved out of the recess by a pressure medium at a high speed until the projection has cleared the recess.
