Abstract:
An injection molding machine for homogenizing a melt and injecting the melt into a mold, comprising:an injection molding cylinder having a foot end and a head end with a funnel-shaped material supply at said foot end and an injection nozzle connectable with the mold at said head end;a material conveyance unit attached to a drive and movable in the interior of the injection molding cylinder for urging the melt through said injection nozzle;a vibration element connected to said injection molding cylinder for producing a relative movement between said injection molding cylinder and said material conveyance unit for generating a flow of the melt in said injection molding cylinder for homogenizing the melt;a frequency generator operatively connected to said vibration element for adjusting a frequency of vibration of said vibration element such that said injection molding cylinder connected to said vibration element is movable in a resonance vibration; said injection molding cylinder being vibrationally decoupled from the mold while said injection nozzle is connected with the mold.
