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.
摘要翻译：在围绕预制的永久插入件注射成型塑料工件时，将第一量的塑料材料注入到一个或多个第一注入腔中，插入件的一部分穿过其中延伸，从而在该部分周围形成相应数量的环形间隔件。在间隔件或间隔件已经固化之后，将间隔物输入的插入件转移到第二注射腔，其中每个间隔件将插入件与相邻腔部分的壁分隔开。然后将第二数量的塑料材料注入到二次注射腔中以通过在包含间隔物或间隔物的插入件周围形成护套来完成工件，所述护套由于注射的二次注射塑料的压力而相互抵消横向运动。

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： A method for injection molding comprises pre-positioning a clamp piston within a cylinder housing to a datum position axially intermediate a clamping position and an unclamped position, the clamp piston affixed to a tie bar, the clamp piston and cylinder housing cooperating to provide a clamp chamber and an unclamp chamber in a clamp cylinder housing on axially opposite sides of the clamp piston for urging the clamp piston towards the clamping and unclamped positions, respectively, when pressurized. Pre-positioning the clamp piston can include leaving a positioning gap between portions of a mold before releasably locking a tie bar to one of the moving or stationary platens, and then advancing the moving platen to substantially close the positioning gap after the releasable locking has been completed. Pre-positioning the clamp piston can include moving a stop member to an advanced position in the cylinder housing, and urging the clamp piston to bear against the stop member before the releasable locking step has been completed.
