    • The present invention is directed to an apparatus mounted to a mold (20) for injecting air into a mold cavity (10) and removing exhaust from the mold cavity (10). The apparatus includes a needle rotation restrictor adapted to fit into a counter bore of a blow cylinder body (30), where the needle rotation restrictor has a hole through which a needle (50) can pass. The blow cylinder body is mountable to the mold and has a conduit to the mold cavity (20) and an interface for interfacing with the mold (20). The interface of the blow cylinder body (30) has a counter-bore for containing the needle rotation restrictor. The apparatus further includes a needle (50) having a cross-sectional shape adapted to restrict rotation within the hole of the needle rotation restrictor and passing through the conduit of the blow cylinder body. The needle rotation restrictor is rotatably positioned within the counter bore prior to engagement of the blow cylinder body (30) with the mold (20).
    • 本发明涉及一种安装到模具(20)上的装置,用于将空气注入模腔(10)并且从模腔(10)中排出废气。 该装置包括适于装配到吹瓶体(30)的反向孔中的针旋转限制器,其中针旋转限制器具有针(50)可以通过的孔。 吹塑筒体可安装到模具上,并且具有到模腔(20)的导管和用于与模具(20)接合的界面。 吹瓶体(30)的接口具有用于容纳针旋转限制器的反孔。 该装置还包括具有适于限制针旋转限制器的孔内的旋转并穿过吹瓶体的导管的横截面形状的针(50)。 在吹塑筒体(30)与模具(20)接合之前,针旋转限制器可旋转地定位在沉孔内。
