Abstract
The present invention relates to an injection unit of a two-stage injection molding machine having an injection device and a meter device for providing plastic to the injection device. The injection motor of the injection device is secured to the base and does not move along with the injection linkage member so as to decrease the movement momentum and improve the injection response and acceleration capability. Additionally, the injection device can adopt a plurality of injection motors for meeting the injection capability requirement without employing high power injection motors. The length of the injection molding machines is relatively shortened, thus the problem of the prior arts is solved.
