AI Technical Summary
During the use of casting sand box positioning equipment, the upper and lower sand boxes are prone to collision and vibration when they are connected, which affects the positioning stability.
An adjustable casting sand box positioning device is adopted, including a base, a lower sand box, an upper sand box, an L-shaped seat, a vertical shaft, washers, springs, and a T-shaped cylinder. When the upper sand box is moved close to the lower sand box by an electric push rod, the T-shaped cylinder slides on the outer circumference of the vertical shaft and uses the spring to provide elastic support and buffering. Combined with the screw connection between the rotating rod and the pin hole, stable positioning and buffering are achieved.
It improves the stability of the upper and lower sand boxes when they are closed, reduces impact and vibration, facilitates the adjustment and replacement of the positioning device as needed, and enhances the guiding and positioning effect.
