Title: AIR DISCHARGING APPARATUS OF TIRE MOLD
Abstract:
An air discharging apparatus of a tire mold is disclosed. The present invention relates to an apparatus wherein an air nozzle comprising a body and a separable cap having coaxially formed inlet holes for discharging air outside a mold and inserted into and coupled to the body is mounted in the mold so as to easily remove rubber protrusions of a tire and dust thereof when the air nozzle is blocked thereby. The apparatus comprises a plurality of perforations formed through a body of a mold, and an air nozzle mounted in each of the perforations, the air nozzle comprising: a cap and a body separably coupled to each other through a coupling part; a dust collecting part having a gap formed between a lower surface portion of a seating part of the cap coupled into the body and an opposite surface of the body; a plurality of inlet holes which are in contact with the upper side of the dust collecting part and are formed through the seating part of the cap; a guide passage which is in contact with the lower side of the dust collecting part and is provided as a recessed groove formed on an outer circumferential surface of the coupling part; a space part which is in contact with the guide passage and is formed in a lower portion of the coupling part; and a discharge passage which is in contact with the space part and is provided as a through hole formed inside the body.
