摘要： An accumulator extrusion head assembly for producing a parison having at least one stripe extending longitudinally thereof comprises an extrusion head body member having an opening extending inwardly from a nozzle outlet end and a mandrel positioned in the body member to define a generally annular extrusion chamber terminating in an annular outlet nozzle. An annular ram is mounted in the extrusion chamber and has a forward end positioned for reciprocation toward and away from the outlet nozzle. A first supply extruder is connected to the body member through first passages for supplying a first extrusion material to the annular extrusion chamber. A second supply extruder is also connected to the body member through second passages for supplying a second extrusion material to the annular extrusion chamber. The second passages include a supply outlet in the forward end of the ram for providing a radially continuous stripe of the second extrusion material to the annular extrusion chamber and, a connecting passage for maintaining a flow connection between the second extruder and the supply outlet during reciprocation of the ram.

摘要： An injection molding apparatus includes a plasticizer (A) for plasticizing plastic pellets. An accumulator head (B) includes a plasticized material receiving entrance (40) for receiving the plasticized material. A mandrel (14) is disposed centrally within the outer body such that an annular cavity (12) is defined therebetween. A ram assembly (16) is mounted in the annular cavity for longitudinally reciprocating motion therein. Reciprocation of the ram assembly urges accumulated plasticized material through a downstream die (C). The ram assembly includes an outer ram member (30), an intermediate ram member (34), and an inner ram member (36). The ram members define a first passage array (60) between the intermediate and outer ram members and a second passage array (70) between the inner and intermediate ram members. The first and second passage arrays are operatively connected with the outer body plasticized material entrance to receive plasticized material therefrom and are operatively connected with the outer body cavity to discharge concentric annular flows of plasticized material thereto.
