摘要： A gas injector having a retractable nozzle with linear gas feed passage therethrough for a gas assist plastics injection molding machine. The injector interfaces with the injection molding tool and has a nozzle with a tip that, in a forward position, protrudes through a port therein leading into the tool cavity or a runner system leading into the cavity for gas injection during molding. The nozzle tip is connected by a nozzle body to a base that is operatively mounted in an actuator housing. The base is connected to an in-line gas routing extension of the nozzle that projects through the outer cover of the housing. The extension is coaxial with an internal spring that seats on the base and holds the nozzle tip in a gas injection position resisting the force of plastics injection pressure. The base connected nozzle is retracted by combined flux fields of an electromagnet and a permanent magnet mounted within the housing while compressively loading the spring enhancing gas release from the cavity tool separation and subsequent ejection of molded part. The electromagnet is then deenergized since the permanent magnet has a sufficient magnetic force field to, hold the base and the attached nozzle in the retracted position. For return to the gas injection position, the electromagnet is again energized but with the current supplied thereto reversed so flux field of the electromagnet is reversed to negate flux field of the permanent magnet allowing the spring to return the nozzle to the forward position.
摘要翻译：一种气体注射器，其具有可伸缩的喷嘴，其具有用于气体辅助塑料注射成型机的线性气体供给通道。注射器与注射成型工具接口并且具有尖端，喷嘴具有尖端，该尖端在向前的位置通过其中的端口突出进入工具空腔，或在模制期间通向导入腔中的气体注入的流道系统。喷嘴头通过喷嘴主体连接到可操作地安装在致动器壳体中的基座。基座连接到喷嘴的在线气体路线延伸部分，其突出通过壳体的外盖。延伸部与位于基座上的内部弹簧同轴，并将喷嘴头保持在抵抗塑料注射压力的气体注射位置。基座连接的喷嘴由安装在壳体内的电磁体和永磁体的组合磁通场缩回，同时从腔模工具分离和随后的模制部件的排出压缩弹簧增强气体释放。然后，电磁体被断电，因为永磁体具有足够的磁力场，将基座和附接的喷嘴保持在缩回位置。为了返回到气体注入位置，电磁体再次通电，但是随着供给的电流反向，电磁体的磁场反转，从而使永久磁铁的磁场不能使弹簧返回到前进位置。

摘要： Gas transmission plugs are placed in a supporting strip portion in plastics injection mold tooling so that an appropriate gas assist injection location can be readily selected, and mated, with a gas injection nozzle thereby eliminating the requirement for pre-drilling mold tooling with gas injection points and removing the tooling from the press so that a gas injection nozzle can be installed relative to the selected injection location. The plugs can be made from porous metal or ceramic with pores that are so small that plastics cannot enter the plug to cause pore clogging. Also, linear gas transmitting passages can be laser beam drilled through plugs of steel or other material with diameters that are sufficiently minute to prevent entry of plastics melt and resultant clogging.

摘要： Apparatus for pulsating gas-assisted injection molding hollow tubular plastic parts includes the injection of a molten plastic into a mold cavity in an amount less than the cavity volume and in separate molten plastic flows that flow along the cavity and ultimately unite in a solidifying fusion welding state at an interface. A pressurized gas is injected into the molten plastic to form a central void in the molten plastic extending to opposite sides of the interface leaving a voidless solidifying fusion weld section encompassing the interface. The gas pressure acting on the opposite sides of the interface is trapped and then alternately increased and decreased by a separate gas injection that creates gas pulsations that effect shifting of the molten weld section in opposite directions to force intermingling of the plastic molecules therein and across the interface to enhance the strength of the fusion weld section on solidification and eliminate appearance knit lines. Reinforcement fibers may be included in the molten plastic and the shifting of the molten weld section orients a number of the reinforcement fibers generally parallel to each other and transverse to and extending across the interface to thereby enhance fusion weld section strength.

摘要： The invention is a method for producing a heat exchanger assembly including the steps of extruding a plastic and an adhesive from a co-extrusion die into a plurality of tubes spaced from each other with each tube having an adhesive disposed on its exterior surface. A plurality of corrugated air fins are serially fed into the co-extrusion die and spaced from each other by a predetermined space and ejected between adjacent tubes with the corrugations extending transversely between the tubes. The adhesive is then cured to secure the tubes to the air fins. The method proceeds by cutting the tubes at each predetermined space with a guillotine shear to produce a plurality of unified heat exchanger cores. The ends of the tubes of each core are inserted into tube slots in manifolds, and the tubes and manifolds are adhesively secured together to define a heat exchanger assembly.
