Heated medium supplying method and structure for secondary molding of resin molding component

摘要

A hot-air supply structure ( 1 ) comprises a hot air generator ( 20 ) and a housing ( 15 ) formed in the neighborhood of a hot-air inlet ( 81 ) of a molded component M in a die ( 10 ). A nozzle ( 21 ) is formed at the forward end of the hot-air generator, and an ejection port ( 211 b) is formed on the side wall portion of the forward end needle unit ( 211 ) of the nozzle. The housing includes a support hole ( 151 ) in the nozzle, a relief hole ( 152 ), a flow path communication passage ( 153 ) and a bypass ( 154 ). The ejection port is movable between a first position to discharge the cool or warm air into the atmosphere through the bypass from the relief hole and a second position to introduce hot air into the flow path ( 8 ) of the molded component through the inlet ( 81 ) and the passage ( 153 ).
