At this time, the rodless cavity of the cylinder is subject to a certain back pressure, and the piston rod is continuously passively pressed back, giving the sand The sand box exerts a reaction force to gradually decelerate the sand box; when the sand box stops completely, the cylinder has a rod cavity for air intake, and the piston rod retracts actively. When the baffle hits the flip plate, the baffle is passively turned up around the rotary axis. , leaving a space for the sand box to pass below it; when the operation of the sand box is completed, the sand box starts again and continues to move from the bottom of the frame to the right; until the sand box completely passes through the device, the cylinder piston rod extends again out, the device returns to the initial state and starts the next box-connecting work.

Compared with the existing technology, the present invention has the following advantages and effects: 1. The structural design is reasonable, and the iron mold is blocked by air pressure buffering, which greatly reduces the inertial impact force of the iron mold and protects the iron mold and The function of the equipment; 2. The device is easy to install, has a simple structure and is highly implementable.
