Method for controlling molten metal material leaking in injection apparatus of metal molding apparatus |
摘要 |
A method for controlling a molten metal material in an injection apparatus that includes a cylinder body with a nozzle at a front end, and a discharge opening on a bottom side of a rear portion. Heating means are provided on an outer periphery of the cylinder body and an injection cylinder is inserted onto an injection plunger for a forward and backward travel within a clearance inside the cylinder body. A material melting and supplying apparatus on a top portion of the injection cylinder has a bottom end outlet communicating with a cylinder body supply opening. Molten metal material accumulates from the supply opening in a cylinder front portion by backward plunge travel and is injected by a forward plunge travel. Heating means maintains the temperature of the molten metal material in front and middle cylinder portions and allows a lower temperature in a rear portion providing a seal metal as well as a lubricant.
