Device for poking sand box backwards

Abstract

The invention relates to a device for poking a sand box backwards. The device comprises a cylinder, wherein the tail end of the cylinder is fixed by a base which is formed by a cylinder fixing seat, and the other end of the cylinder is provided with a retracted piston rod; the head of the piston rod is hinged to a bump which is hinged to a positioning base; a supporting position is formed on the outer edge surface of the bump; and the bump is driven by the piston rod serving as a push rod to rotate along a base rotating shaft of the bump so as to form poking force for driving the offset sand box to a set position at the supporting position of the outer edge surface of the bump. In the device, through the driving of the push rod of the cylinder, the force is transferred by the bump and applied to the outer surface of the offset sand boxy so as to poke the sand box backwards.

Description

technical field [0001] The invention relates to a sand box callback device used for adjusting the position of the sand box on the side roller frame before the box closing machine closes the box in casting molding. Background technique [0002] In the casting molding automatic line, when the box closing machine closes the box, it needs to be operated by the manipulator to lift the upper box and transport it to the top of the lower mold line along the horizontal position for positioning, and it is stably closed on the lower mold under the action of the push rod, and then through positioning Pins are further secured. After the binning is completed, the upper and lower boxes leave the binning position together with the track for follow-up operations. [0003] The initial position of the sand box will directly affect the efficiency and difficulty of the subsequent operation. If the initial position can be basically placed as required, the operation efficiency will be greatly imp...

Problems solved by technology

[0003] The initial position of the sand box will directly affect the efficiency and difficulty of the subsequent operation. If the initial position can be basically placed as required, the operation efficiency will be greatly improved; because when the sand box is picked up from the side roller stand , if the positioning of the sand box on the side roller frame is not accurate, the position when picking up the sand box will be different, resulting in inconsistent data every time the box is combined, and the upper and lower sand boxes cannot be combined quickly and smoothly
