    • An injection molding apparatus for manufacturing hollow objects, such as plastic e.g. multi-layered preforms, comprising an injection mold (1) with a front (2) and a rear side (3), which is composed of a clamp plate (4) on the front side (2), and a hot runner plate (5), where a manifold (6) is mounted in the hot runner plate, between which a set of injection nozzles (7) is arranged, which are each provided with a central supply duct (8), at the free end (9) whereof an injection gate (10) is provided. Said apparatus is remarkable in that said injection gate (10) is closable by means of a locking rod (11), which is movable herein to and fro through a profiled inner part (12) which is received in a holder (13) around which a heating element (14) is provided into which a primary channel (15) opens for supplying the plastic base material to the injection gate (10). Each injection nozzle (7) is directly removable individually from the injection side (16) of the injection mold at the injection side thereof, and a respective secondary channel (17) is provided separately; and method therefor.
    • 一种用于制造中空物体的注射成型设备,例如塑料 包括具有前侧(2)和后侧(3)的注射模具(1)的多层预成型件,其由前侧(2)上的夹板(4)和热流道板 如图5所示,其中歧管(6)安装在热流道板中,其间布置有一组注射喷嘴(7),每个喷嘴(7)在自由端(9)处设置有中央供应管道(8) 其中设置有注入口(10)。 所述装置是显着的,其中所述注射门(10)可通过锁定杆(11)关闭,所述锁定杆(11)可在此通过形成在其中的保持器(13)内的成型内部部件(12)和/ 提供加热元件(14),主通道(15)打开以将塑料基材供应到注入口(10)。 每个注射喷嘴(7)可以在其注射侧从注射模具的注射侧(16)分别直接移除,并且分别设置相应的辅助通道(17) 及其方法。
