用于将预成型的塑料塑型成塑料容器的成型装置
Abstract:
本发明涉及成型装置（1），用于将预成型的塑料（10）塑型成塑料容器（10A），所述成型装置（1）具有多个吹塑点（8）和至少一控制设备（55；55A；55B；55C），所述控制设备用于控制在吹塑点（8）吹塑压力和/或容积流量，其中所述的至少一控制设备（55；55A；55B；55C）包含至少一控制阀（56），所述控制阀（56）带有一控制活塞部件（58），所述控制活塞部件（58）由圆柱形部件（57）引导，依靠圆柱形部件（57）一吹塑空气导管（60）的横截面（59）可以被关闭，其中所述控制设备（55；55A；55B；55C）具有一以电磁方式运行的驱动元件（61；77），以便于对圆柱体部件（57）内的控制活塞部件（58）产生一个位置的改变，并且因而也控制了在成型点（8）上的吹塑压力和/或容积流量。
Abstract(English):

The invention relates to a shaping apparatus (1) for the shaping of plastics material pre-forms (10) into plastics material containers (10A) with a plurality of blow moulding stations (8) and with at least one control device (55; 55A; 55B; 55C) for the control of blow moulding pressures and/or volume flows at the blow moulding stations (8), in which the at least one control device (55; 55A; 55B; 55C) comprises at least one control valve (56) with a control piston part (58) which is guided in a cylinder part (57) and by means of which a cross-section (59) of a blow moulding air duct (60) is capable of being closed, wherein the control device (55; 55A; 55B; 55C) has a drive unit (61) operating in an electromagnetic manner in order to effect a change in position of the control piston part (58) inside the cylinder part (57) and thus also to control the blow moulding pressures and/or volume flows at the blow moulding stations (8).
