摘要： In order to feed molten metal to a casting mold with precision while preventing introduction of metal oxide into a cylinder casing, an entire valve box 19 is disposed below a liquid level of the molten metal C inside a molten metal furnace D. A discharge duct 23 is upwardly open at a lower end of a valve-element moving space 24. An inlet duct 22 is open to the valve-element moving space 24 at a position higher than the discharge duct 23. Around an opening of the discharge duct 23 to the valve-element moving space 24, there is formed a lower receiving seat 29 in the form of a ring. A valve element 21 includes a lower contact portion 31 which comes into annular contact with the lower receiving seat 29 in association with a lowering movement of the valve element 21. The molten metal C inside the molten metal furnace D is introduced into a cylinder casing 4 by moving the valve element 21 to an inlet position where the lower contact portion 31 comes into the annular contact with the lower receiving seat 29 thereby to block communication between the discharge duct 23 and an inlet/outlet duct 8.

摘要： A method of injection molding for use with an injection molding machine (10) includes: (a) generating pressurized gas and pressurized moisture within molten plastic as plastic pellets are plasticized in the injection molding machine (10), the pressurized gas and the pressurized moisture having a total pressure defining an internal counterpressure within the molten plastic; (b) pressuring air within a cavity (30) of a mold (22) in the injection molding machine (10) to an air pressure level which is substantially equal to the internal counterpressure in order to counterbalance the internal counterpressure as the molten plastic is injected into the cavity (30), thus providing a substantially pressure balanced molding environment for the plastic; and (c) maintaining the air pressure level in the cavity (30) substantially constant as the molten plastic is injected into the cavity (30). A mold apparatus for use with the method of injection molding includes selectively sealed venting of the mold cavity (30), the vents (42) being configured to maintain a substantially constant air pressure within the cavity (30) as the cavity (30) is filled with molten plastic.

摘要： A method of injecting molten plastic or molten metal into a cavity (120) to form a desired part shape is provided. The method includes: (a) providing pressurized gas in the mold cavity (120) prior to injection of molten material into the cavity (120); (b) generating a melt pressure sufficient to inject the molten material into the cavity (120); and (c) providing a closed loop controller (152) to maintain a controllable difference between the melt pressure and the pressure of gas in the cavity (120) throughout a substantial portion of a period of time during which molten material is being injected into the cavity (120) to improve the conditions under which the material solidifies. By preloading the system with static pressure, conditions are created which allow generation, measurement and real time control of pressure difference profiles during transition of the melt throughout the injection cycle.

摘要： An injection molding system for a metal alloy includes a feeder in which the metal alloy is melted and a barrel in which the liquid metal alloy is converted into a thixotropic state. An accumulation chamber draws in the metal alloy in the thixotropic state through a valve disposed in an opening between the barrel and the accumulation chamber. The valve selectively opens and closes the opening in response to a pressure differential between the accumulation chamber and the barrel. After the metal alloy in the thixotropic state is drawn in, it is injected through an exit port provided on the accumulation chamber. The exit port has a variable heating device disposed around it. This heating device cycles the temperature near the exit port between an upper limit and a lower limit. The temperature is cycled to an upper limit when the metal alloy in the thixotropic state is injected and to a lower limit when the metal alloy in the thixotropic state is drawn into the accumulation chamber from the barrel.
