The injection molding instrument, the packing container which has the shedding mechanism which injection molding method and it ejected formed

摘要

As for this disclosure the hole edge part (8) the packing material which picture forming is done (9) the shedding mechanism (20) the instrument which it ejects forms (1a and 1b, 2) being, first side of the packing material which it is related with the aforementioned hole edge part (9a) the part and second side (9b) with the part the hole edge part (8) the mold cavity which is surrounded (7) to form in the hole, the aforementioned mold cavity (7) the entrance for the melted plastic (10) with, on opposite side to the said entrance from the aforementioned instrument the packing material (9) extending the edge air gap in order to be present (11) with it possesses, the aforementioned entrance (10) flows and in the air gap (5) the first machine direction (F₁) from the mold cavity (7) second machine direction to in (F₂) to it regards the injection molding instrument which forms the deflection section. According to this invention, the aforementioned instrument (1a and 1b) it forms the aforementioned first direction (F₁) with the contraction lip which projects to the direction which agrees in general (12) the aforementioned entrance (10) in. In addition as for this invention, the shedding mechanism which injection molding method and it ejected formed (20) it regards also the packing container which it has.
