    • A method and apparatus for injection molding of high quality thermoplastic parts is such that a conventional movable mold half is mounted on a movable platen of the injection molding machine, and a special stationary mold half is mounted on the stationary platen. The stationary mold half includes a stationary plate secured to the stationary platen, with the stationary plate including stationary mold inserts. Each stationary mold insert has a stationary mold insert surface. An A-half parting line plate is movably attached to the stationary plate, with the A-half parting line plate being movable with respect to the stationary plate and the stationary mold inserts. A driving device, such as a hydraulic cylinder, is disposed between the stationary plate and the A-half parting line plate, with the driving device driving the A-half parting line plate toward and away from the stationary plate. A control circuit is provided for controlling the driving device to control a movement of the A-half parting line plate with respect to the stationary plate.
    • 用于注塑成型高品质热塑性部件的方法和装置是这样的:将传统的可移动半模安装在注射成型机的可移动压板上,并且在固定压板上安装特殊的固定半模。 固定模具半部包括固定在固定压板上的固定板,固定板包括固定模具插入件。 每个固定模具插入件具有固定的模具插入表面。 一个半分割线板可移动地连接到固定板上,其中A半分割线板可相对于固定板和固定模具插入件移动。 驱动装置如液压缸设置在固定板和A半分割线板之间,驱动装置驱动A-half分型线板朝向和远离固定板。 提供控制电路用于控制驱动装置以控制半分离线板相对于固定板的移动。
