摘要： A single screw injection device or extruder sequentially injects skin and foamed plastics melts into a mold to produce structural skin covered foam molded parts free from swirl marks. A single extrusion screw or plasticator selectively feeds, compresses and meters a plastics melt to a first injector for skin melt injection or to a gas injection well where it meters gas flow into the melt, mixes the gas and melt to form a foam and feeds the foam to a second injector for foam melt injection into the mold. A valve controls the flow of the plastics melt and the foamed plastics melt to a single injection nozzle for discharge into the mold. In sandwich molding, a small amount of the unfoamed melt is first injected to form the skin for the molded article and then the valve is shifted to connect the nozzle with the foamed melt from the screw whereupon the injector forces the foamed melt through the nozzle into the mold to overlie the skin melt. The skin melt and the foamed melt are fed through the same nozzle and swirling in the mold is avoided.

摘要： An oven for heating tubular parisons to a target or orientation temperature. A first plenum on one side of the oven and a second plenum on the opposite side of the oven, both exhaust to a common chamber disposed therebetween. The parisons are heated by a high velocity fluid above the target temperature in the zone defined by the first plenum and the chamber and the parisons are tempered by a lower velocity fluid at the target temperature in the zone defined by the second plenum and the chamber.

摘要： A blow molding assembly for thermoplastic resins, used, for example, for the manufacture of bottles wherein parisons are heated in an oven and then transported to a mold station where they are biaxially oriented and blown. The invention is particularly concerned with a transport system operating from the oven to the molds, wherein the spacing between the various parisons being transported by means of picker means can be adjusted so that the parisons may be introduced into molds at a spacing different from the spacing of the parisons in their travel through the oven. The transport system includes means for picking off parisons from a conveyor with a predetermined spacing and means for spreading or narrowing the spacing to match the centerline-to-centerline spacing of the molds.

摘要： A screw for use in the bore of an extruder barrel of a molding machine thermo-plastics material feeder has an intermediate section of circumferentially interrupted helical flights or screw threads with inclined ramps on the leading ends of the interrupted flights or threads effective to flatten unmelted lumps of plastics material for increasing the surface area thereof to enhance heat transfer for expediting melting of the material. The tapered ramps are preferably longitudinally grooved forming shallow pockets gripping the plastics material and shearing the lumps as they are wedged between the ramps and bore of the extruder barrel. The peripheries of the flights or screw threads are spaced from the bore of the extruder barrel to define extrusion gaps therebetween with the gaps diminishing in thickness from the inlet to the outlet ends of the screw section or zone. The screw section or zone is positioned intermediate the ends of the screw to receive the thermo-plastics material in a partially melted condition composed of about 50 percent molten flowable material and about 50 percent of solid material and the flights or screw threads of the section discharge fully melted thermo-plastics material to a cascading mixing section or zone having axially spaced barrier rings with advancing and reversing flight lengths. The reversing flights terminate radially inward from the bore of the extrusion barrel providing shear gaps to mix the molten material with the gaps decreasing in thickness from the inlet to the outlet ends of the mixing section.

摘要： An improvement is provided for plastic molding machinery of the type comprising a plastic melt injection apparatus and a mold. A shut-off valve which provides communication between the injection apparatus and the mold, includes a single elongate passageway and an elongate shut-off piston oriented generally parallel to the flow path and mounted in the passageway by a housing, which housing is supported by a single, streamlined leg so that the plastic melt flows therethrough in a single, undivided flow path. The melt flow path, as defined by the passageway and housing mounted therein has a generally circular transverse cross-section at an upstream station and a generally U-shaped transverse cross-section at a station downstream of the circular station. An aspect of the improvement is a plug-shaped tip formed integrally on the downstream end of the piston for expelling residue and cleaning the outlet port especially in structural foam molding applications. A further aspect of the improvement is an elongate nozzle for molding applications with larger molder sizes that require an extra long injection reach.

摘要： An apparatus for transferring parisons from an oven to a blow mold has the capability of straightening up tilted parisons and gripping them uniformly without flattening the ends. The apparatus includes a gripper with jaws which open wide when opened, thereby providing an entry space between the jaws for a tilted parison as well as an upright parison and which in the closed position form an essentially complete circle about the parison to uniformly grip the same in cooperation with a push piece which moves into the open end of the parison.

摘要： An injection molding machine having a barrel and a reciprocating and rotatable screw disposed therein. A combination heat transfer and stratification device is disposed between the screw and the outlet of the barrel. The device includes a generally tubular portion having radially outwardly extending ribs. The ribs are in contact with the inner wall of the barrel. Heating means supply heat to the portion of the barrel containing the device and heat is transmitted through the rib portions. A process is disclosed whereby plastic is partially melted in the screw section and then stratified for final melting and thereby reduces mixing to provide a mottled appearance or plastic parts containing long fine filaments such as fine wires.
