Abstract
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.
