A mold opening and closing device and a mold opening and closing method
ActiveCN116653242BEasy to take modulusRealize the function of turning over the moldGlass productionFixed framePhysics
This invention relates to the field of mold opening and closing technology, and particularly to a mold opening and closing device and method, including a mold station frame, a bottom mold, a frame, a top mold, a fixed frame, a limiting mechanism, a flipping mechanism, a clamping mechanism, and a lifting mechanism. A baffle protruding outwards is provided on one side of the top mold. The flipping mechanism connects the clamping mechanism and the lifting mechanism. The lifting mechanism is connected to the clamping mechanism and is used to drive the clamping mechanism to lift the frame up and down. When the clamping mechanism is in a high position, it can be flipped around the flipping mechanism along one side. The fixed frame is located above the mold station frame. The limiting mechanism includes a first driving member and a limiting plate. The first driving member is located on the fixed frame and connected to the limiting plate, and is used to drive the limiting plate to move up and down towards the mold station frame. The limiting plate restricts the top mold in an upward flipping state. When the limiting plate restricts the top mold, the lifting mechanism in a descending state can separate the frame from the top mold, achieving the function of automatically opening the frame.
