摘要： An apparatus for use in gas assisted injection molding of plastic material so as to form an injection molded product includes a pair of mold members defining when closed a sealed cavity. A first opening is provided in one of the mold members for allowing the injection of a plastic material into the cavity. A device is provided to supply a pressurized gas and a second opening is provided in one of the mold members for allowing the injection of the pressurized gas into the cavity. A probe is located in the second opening and is adapted to be reciprocated therein from a retracted position to an extended position. The probe has a first end adapted to selectively extend into the cavity, a second end, and a longitudinally extending bore which terminates in a port located adjacent the first end. The bore is used to guide the gas into the cavity. A device is provided for reciprocating the probe in relation to the cavity. A control system controls the operation of the device for reciprocating as well as the device for supplying a gas.

摘要： Apparatus for producing an injection moulding of plastics material comprises means for introducing a supply of plastics material, passage means for communicating the supply means to a mould space, and means for introducing a pressurized gas into the plastics material filling the mould space whereby the gas creates a gas containing cavity in the plastics material and for thereafter relieving the gas pressure within the gas containing cavity before the mould is opened. The gas supply/pressure relieving means comprise valve means including a valve port opening directly into the mould space, for opening the gas filled cavity to the atmosphere, a valve member for closing the port, and means to supply pressurized gas to the mould while the valve member is in the port closing position to create the cavity and to maintain the valve port open to the cavity whereby, after a moulding operation has been finished, the supply of pressurized gas can be terminated and pressurized gas in the cavity in the moulding can be vented to atmosphere by opening the valve member.

摘要： A method and apparatus for making a twin-wall internally corrugated plastic structural part provided with a smooth, dense, solid, thin walled, non-cellular skin comprising injecting a thermoplastic or resin material into a pair of closed mold members which define a sealed cavity. A small amount of plastic material is initially injected into the cavity with the material impinging upon and being dispersed over the mold members thereby forming a generally continuous thin skin substantially the mold surfaces. Thereafter, successively and intermittently injecting an inert gas under pressure through one mold member during continued injection of the plastic material into the cavity thereby pressurizing the skin against the walls of the mold cavity and progressively commingling the inert gas under pressure and the inwardly flowing plastic material as both enter the cavity until the cavity is filled with an internal corrugated body integral with and bonded to the skin. Further steps include cooling the twin-wall internally corrugated structural part to permit the same to solidify as an integral unit and venting the mold cavity to atmosphere to relieve pressure from the corrugated plastic structural part. The intermittent injection of the inert gas introduces minute amounts of pressurized gas into the continuously injected plastic material.

摘要： A hot runner nozzle assembly includes a nozzle heater, a hot runner nozzle, a nozzle tip, a nozzle tip seal surrounding the nozzle tip and a connecting element positioned to removably couple the tip seal to the nozzle tip and to create a first contact seal between the nozzle tip and the tip seal and a second annular contact seal between the tip seal and a mold component. The nozzle tip is made or shaped via a sintering process from a metal matrix composite (MMC) material having a first coefficient of thermal expansion. The tip seal is made or shaped from a ceramic based powder material, having a second coefficient of thermal expansion that is different from the first coefficient of thermal expansion. In operation this hot runner nozzle assembly provides an improved heat profile and a reduced leakage at the tip area under a wider operating processing window.

摘要： A gas injecting device for an injection molding machine is equipped at one side of a cylinder of the injection molding machine, and includes a pin inserted into a gas injection hole of the gas injecting device. The pin has flat sections formed around an outer lower portion of the pin to define gaps between the flat sections and an inner surface of the gas injection hole, such that a gas is injected uniformly through the gaps, thereby allowing the gas and a resin to be easily mixed while preventing the resin from flowing backwards through the gas injecting device. An amount of gas injected to a barrel of the injection molding machine is accurately controlled according to a pressure difference between a gas line and the barrel, and time data, allowing an article to be injection molded according to a kind of resin or characteristics of the article.

摘要： A method and system for forming an injection molded plastic part. After the injection of plastic material has started, a volume of gas from a fixed volume reservoir is introduced into the plastic material at a low pressure forming a hollow cavity. The introduction of this volume of gas is initiated when the temperature of the plastic material in the mold has reached a predetermined value. After the mold is filled and packed with plastic, pressurized gas is introduced into the hollow cavity forming the completed plastic part.
