拉伸吹塑成型机
摘要：
本发明提供一种拉伸吹塑成型机(1)，其具有至少一个吹塑成型台(4)，在吹塑成型台(4)中设置了开口吹塑模(26)、具有阀门部分(12)的可调节吹塑喷嘴(8)、具有拉伸杆驱动系统的拉伸杆(15)，和电子控制单元(20)，布置在吹塑成型台(4)中的电子控制单元(20)装备有选择性利用包括凸轮驱动器和气动驱动器的组合，或电气伺服驱动器和气动驱动器的组合，或仅电气伺服驱动器对吹塑成型台(4)操作的硬件和软件技术。根据方法，在吹塑模锁止阶段开始或期间和放置吹塑喷嘴(8)前，在容器生产工艺中借助电气伺服电机(16)在拉伸吹塑成型机中启动拉伸杆(15)的运动，且拉伸杆(15)已移动到拉伸杆(15)非常靠近地接近预成型坯底部或者接触预成型坯底部的位置，或在放置吹塑喷嘴(8)前已对预成型坯进行了预拉伸。
摘要（英）：

A stretch-blow molding machine 1 having at least one blow molding station 4, in which a split blow mold 26, an adjustable blow nozzle 8 with a valve section 12, a stretching rod 15 with a stretching rod drive system, and an electronic control unit 20 are provided, the electronic control unit arranged in the blow molding station is equipped with hardware and software for selectively operating the blow molding station 4 with a combination of a cam drive and a pneumatic drive, or a combination of an electric servo drive and a pneumatic drive, or only an electric servo drive in the stretching rod drive system. The movement of the stretching rod is initiated in the stretch-blow molding machine in the production process of a container by means of an electric servomotor 16 with the beginning of or during the locking phase of the blow mold and before the blow nozzle 8 is placed, and the stretching rod 15 is already displaced to a position in which the stretching rod 15 is either very closely approached to the preform bottom or contacts the preform bottom, or has even already pre-stretched the preform, until the blow nozzle 8 is placed.
