Turnover mechanism for rapidly replacing sealing ring of sand casting machine

Abstract

The invention relates to the technical field of sand casting, and discloses a turnover mechanism for rapidly replacing a sealing ring of a sand casting machine. The mechanism comprises a limiting clamping block which is connected with the upper end of the sand inlet of a lower gas storage chamber, a transition plate hinged to the limiting clamping block, a turnover plate which is connected with one side of the transition plate and a nitrogen spring connected with the turnover plate, the lower end of the turnover plate is connected with the upper end of the liner of the sand inlet, the side, back to the transition plate, of the turnover plate abuts against an outer plate of the sand outlet, the upper side of the transition plate is connected with the lower side of the turnover plate througha screw, the lower side of the transition plate is connected with the upper side of the liner of the sand inlet through a screw, the telescopic end of the nitrogen spring is connected with the lateral side of the lower gas storage chamber, and the other end is connected with the turnover plate. According to the mechanism, when the sealing ring is damaged, the screw between the transition plate and the upper side of the liner of the sand inlet is released firstly, the turnover plate is stably rotated through the nitrogen string to take down the sealing ring, and the mechanism can save time andstrength.

Description

technical field [0001] The invention relates to the technical field of sand casting, in particular to a turning mechanism for quickly replacing the sealing ring of a sand casting machine. Background technique [0002] Sand casting is the basic process of foundry processing. Sand casting directly affects the casting effect of the final product. Sand casting machine is a large-scale equipment that needs to be used in the sand casting process, including sand cylinders, upper elbows, upper gas storage bins, and lower elbows. , lower gas storage bin, upper sand box, lower sand box, etc., wherein the sand cylinder is connected to the upper gas storage bin through the upper elbow, and the lower gas storage bin is connected through the lower elbow, and the upper gas storage bin is connected to the upper sand box, and the lower The gas storage bin is connected with the lower sand box. In the sand casting process, the mold is first placed between the upper sand box and the lower sand...

AI Technical Summary

Problems solved by technology

[0003] The sand outlet of the lower elbow of the sand casting machine is provided with a sealing ring, which can improve the sealing performance of the sand blowing of the lower gas storage bin, but when the lower gas storage bin moves up and down, the sand inlet of the lower gas storage bin The lining plate is easy to cause wear to the sealing ring, and the sealing ring is easy to be damaged after a long time. Because the outer plate of the sand outlet and the lining board of the sand inlet are respectively connected with the lower elbow and the lower gas storage chamber by screws, and the two are a whole piece. Large steel plate, heavy weight, very difficult to disassemble, making it difficult to replace the sealing ring
