Abstract:
A vibration applying apparatus associated with an injection molding machine for applying vibrational repetitive movements to a melt of molding materials while the melt is held within a heating cylinder of the injection molding machine, the vibration applying apparatus comprising:a rod having one end received inside the heating cylinder and disposed in the proximity of a nozzle of the heating cylinder;a stationary guide supporting the rod such that the rod is movable back and forth;a rotating shaft being orthogonal to the rod;a drive motor for rotating the rotating shaft; anda cam mechanism acting between the rotating shaft and the rod so as to convert rotary motion of the rotating shaft into linear reciprocal motion of the rod, whereby vibrational repetitive movements are applied from the one end of the reciprocating rod to the melt of molding material.
