摘要： In an integrated system, plastic articles are produced in a pressure-molding machine and transferred therefrom to pallets at a receiving station. These pallets are entrained by a first branch of a conveyor which carries them through a temperature-conditioning station to an aftertreatment station in which a finishing operation such as blow-molding is performed upon the articles by a mold with which each pallet is temporarily consolidated. The pallets subsequently carry the finished articles to a discharge station and, upon their removal, are returned empty by a second conveyor branch to the receiving station.

摘要： In injection-molding a plastic workpiece about a prefabricated permanent insert, a first quantity of plastic material is injected into one or more first-shot cavities through which a portion of the insert extends, thereby forming a corresponding number of annular spacers around that portion. After the spacer or spacers have solidified, the spacer-carrying insert is transferred to a second-shot cavity in which each spacer holds the insert separated from the walls of adjoining cavity sections. A second quantity of plastic material is then injected into the second-shot cavity to complete the workpiece by forming a sheath around the insert incorporating the spacer or spacers which are steadying same against lateral movement due to the pressure of the injected second-shot plastic.

摘要： A nozzle for the introduction of liquefied plastic material into a mold has a channel terminating at one end in an injection orifice and adjoining at its other end a reduced bore serving for the guidance of a valve pin slidable with all-around clearance in that channel, the pin having a rear extremity projecting from its guide bore. A passage for the admission of liquefied molding material under pressure enters the channel at its junction with the reduced guide bore, rearwardly of a set of skew fins of the pin serving for additional guidance thereof in the channel and for imparting relative rotary motion to the flow and the pin. The orifice is blocked at the end of an injection operation by a pusher acting upon the projecting rear extremity; it is unblocked, upon withdrawal of the pusher, by the pressure of the molding material in the channel upon a forwardly facing annular shoulder of the pin.

摘要： A nozzle for the injection of liquefied plastic material into the gate of a mold cavity has a tubular metallic body forming a sprue, the outer surface of this body being in contact with an annular heater in the shape of a closed shell whose interior is filled with a matrix of compacted MgO powder having one or more resistance wires embedded therein. The heater is held in position by a nut, threaded onto a gate-side extremity of the body, against a shoulder or a tapering surface portion thereof and is separated by an air space from a surrounding supporting structure.

摘要： An injection gate of a mold cavity comprises an elongate valve rod which passes axially through a flow channel for molten plastic material and is guided in an extension of a thin-walled steel cylinder open at its opposite end toward an adjoining manifold plate. The rod extremity remote from the gate is secured to a tubular neck of a piston inside the cylinder whose stroke length is a fraction of the axial height of the cylinder's interior, a clearance around this neck providing space for drooling plastic while the length of the neck and of the peripheral cylinder wall serves for thermally insulating the manifold plate from the flow channel. The piston has a head sliding within an internal annular shoulder of the cylinder wall, proximal to the manifold plate, which is traversed by axially oriented bores communicating with the aforementioned clearance whereby pressure fluid such as compressed air can be selectively admitted from conduits in the manifold plate to either side of the piston head for reciprocating same together with the valve rod. A plurality of such valve-control pistons can be connected to these conduits in parallel for simultaneous actuation by the air pressure applied thereto.

摘要： An injection molding machine includes a base, a stationary platen fixed to the base for holding a first mold section, and a moving platen for holding a second mold section. The moving platen is slidably supported on a platen slide surface fixed to the base and moveable along a machine axis between a mold closed position, in which the moving platen is drawn towards the stationary platen, and a maximum daylight position, in which the moveable platen is spaced axially apart from the stationary platen by a platen opening. The machine further includes a carriage support structure slidably supporting a stack mold carriage for holding a mold center section. The stack mold carriage is translatable parallel to the machine axis between a carriage advanced position and a carriage retracted position spaced axially apart from the carriage advanced position by a carriage stroke length. The carriage support structure includes a pair of beams removably fixed relative to the base, the beams extending parallel to the machine axis and spaced apart from each other by a lateral spacing, each beam having a beam length that is less than the platen opening and greater than the carriage stroke length.

摘要： An injection molding machine can include a base, a stationary platen fixed to the base for holding a first mold section and a moving platen for holding a second mold section. The moving platen can be slidably supported on a platen slide surface fixed to the base. The injection molding machine can also include a stack mold carriage for holding a mold center section. An actuator can be coupled to the stack mold carriage for translating the stack mold carriage along the machine axis towards and away from the stationary platen, the actuator comprising a driven member coupled to a carriage connection portion. The carriage connection portion can transfer motion from the driven member to translation of the stack mold carriage. The carriage connection portion can be joined to the stack mold carriage at an elevation below the platen slide surface.
