The present invention relates to a two-plate injection molding machine capable of electric mold opening/closing, comprising a machine base, a fixed mold plate, a movable mold plate, and a mold opening/closing device, wherein the mold opening/closing device comprises a mold locking mechanism, a mold moving mechanism, and a mold clamping mechanism. In the present invention, on the one hand, a middle clamping high-pressure cylinder and a plurality of clamping tie rods work together to apply force on a mold, such that the mold is clamped under relatively uniform stress, thereby improving mold clamping accuracy; on the other hand, mold moving and mold clamping can be performed synchronously without pause, such that not only is the process simple and rapid, but the mold positioning accuracy and mold opening/closing repetition precision can be effectively improved. In addition, the opening/closing of the mold can be achieved without a reset action of the clamping tie rods, such that the action is smooth, and the idle cycle (dry cycle) of the injection molding machine itself is also shortened.

Disclosed is a plasticizing power and injection power synergistic high-performance injection molding machine, comprising a casing, a barrel, a screw, a pressure sensor, and a power system. The power system comprises a sleeve, a plasticizing drive member, a transmission member, a connection member, a nut, and an injection drive member; the transmission member is a double-headed screw that has threads that rotate in opposite directions, one threaded section of the double-headed screw matches an inner thread pair of the sleeve, the other threaded section thereof matches an inner thread pair of the nut, and the end part of the other threaded section emerges from the outer end part of the nut. By means of the joint synergy of the different rotation speeds and rotation directions of the sleeve and the nut, the present invention can drive the double-headed screw to move linearly or rotationally to drive the screw to move synchronously. Therefore, the rated power of a motor in an injection unit is greatly reduced as compared to an existing injection molding machine. At the same time, the present invention has a compact structure, and moving parts thereof have little inertia. The present invention responds quickly, can effectively expand the injection molding process window, and improve product stability and yield.
