摘要: A method and mold for making an ampule for a needleless or jet injector device. The tip of a core pin is guided into a clearance hole sufficiently large to prevent the tip from hitting the mold cavity. Plastic is injected into the mold and flows into the space between the core pin tip and the clearance hole forming a vestigial nozzle pilot cylinder around and over the ampule nozzle. The ampule is removed from the mold and the vestigial nozzle pilot cylinder is removed to form a finished ampule. A core pin tip is made of drawn wire or is separately replaceable on the core pin. A nozzle of an ampule is cast in place. An ampule is molded with an enlarged nozzle and a separate orifice is installed in the ampule to provide the desired nozzle opening.
摘要翻译: 一种用于制造无针或喷射装置的安瓿的方法和模具。 芯销的尖端被引导到足够大的间隙孔中,以防止尖端撞击模腔。 将塑料注射到模具中并流入芯销尖端和间隙孔之间的空间,在安瓿喷嘴周围和上方形成残留喷嘴先导筒。 将安瓿从模具中取出,并且去除残留喷嘴引导筒以形成成品安瓿。 芯针尖由拉丝制成,或者在芯针上单独更换。 将安瓿的喷嘴浇注到位。 用扩大的喷嘴模制安瓿,并在安瓿中安装独立的孔,以提供所需的喷嘴开口。
