Abstract

An apparatus for cleaning plastics forming mold faces comprising composite brushes each consisting of a vibratory brush adapted to be vibrated in a vertical direction or in unspecified directions by a vibrating mechanism, and a rotary brush annularly surrounding the vibratory brush and adapted to be rotated in a horizontal direction, the composite brushes being disposed in opposed relation to the faces of two mold halves, a dirt sucking mechanism having a vacuum source for sucking and removing flash peeled from the mold faces by the vibratory and rotary brushes, and an air blowing mechanism for blowing air against the mold faces to cool the flash so as to enhance the flash peeling action of the vibratory and rotary brushes.
