Zusammenfassung: | PURPOSE:To sufficiently execute cleaning of a die and to prevent the malfunction of an ejecting pin. CONSTITUTION:An air blowing nozzle for a die is formed in the inner part of the ejecting pin 6 and has a passage 6a for continuously supplying air for blowing. Further, this has a nozzle part formed as communicating with the passage 6a to the ejecting pin 6 and set to the positional relation coming to the upper part from the bottom part 4a in a cavity 4 when the ejecting pin 6 projects from pin hole 4a. Then, this nozzle part directs the direction flowing the air for blowing along the bottom face 4a in the cavity 4. By this constitution, when the nozzle part 6b comes to the upper part from the bottom part 4a in the cavity 4 by ascending the ejecting pin 6, the air blown out from the nozzle part 6b flows along the bottom face 4a in the cavity 4 and can be blown off without raising foreign matter. Further, as the air can be blown from a gap between the ejecting pin 6 and the pin hole 4a, the foreign matter hardly invade into this gap. |
