The invention relates to the technical field of injection molding equipment, and provides an intelligent injection molding
liquid injection device capable of realizing no bubbles by employing a springmechanism. The device comprises an injection molding
liquid injection device, upper pressing devices are fixedly connected to the left side and the right side of the injection molding
liquid injection device, torque springs are respectively and movably connected to the left side and the right side of the injection molding liquid
injection device through the upper pressing devices, and sound waveblocks are respectively and movably connected to the left side and the right side of the injection molding liquid
injection device through the upper pressing devices. According to the intelligent injection molding liquid
injection device capable of realizing no bubbles by employing the spring mechanism, intermittent touch of a pulling connecting rod is performed through the rotation of a transmission tank, injection molding, stirring and conveying are conducted in a rotating wheel
driving mode, when the device is in a high-load state, a
chassis thereof shakes to a certain extent, the
chassis touches the pulling connecting rod, the pulling connecting rod drives a negative pressure spring to be further compressed in an original working state through a movable
extrusion frame, and a limitingrotating rod is driven to move to the edges of two sides of a transmission rotating rod.
