ABSTRACT:
An injection molder with two movable molds is composed of a mold-matching device, an injection device, a hydraulic system and an electric control system, which only uses two movable molds, by means of the action of same oil cylinder to continuously complete mold-matching, mold-separating, integrated movement, integrated recession and injection and technological processes without transform of various motions, and wherein, the pressure of the injection is used to lock molds, so the mold-locking force is larger. The molder is short in total length, small in size, compact in structure and low in manufacturing cost, and can be used not only for a plunger injection molder and a screw injection molder, but also for other special injection molders or precision injection molders.
